Zhou Cang was completely impressed by Qingcang's performance just now.
The scene just now could be said to have refreshed his knowledge and was also very thrilling.
If you want to rush through Tongguan, which is full of cannons.
How much courage does that require?
How much mental toughness does it require?
In his opinion, all of this is impossible.
But in the end it seems.
Qingcang also really succeeded.
They passed Tongguan safely.
"Commander, you see it's smoke.
They lit it."
Zhou Cang pointed at the wolf smoke behind him and said.
It was the smoke of the wolf, and they actually lit the wolf smoke.
Qing Cang nodded to express his understanding and switched the swamp air boat to autopilot mode.
He understood the significance of the smoke.
Cao Jun wanted to notify the defenders downstream and let them intercept the two of them.
This is probably the fastest way.
But no matter how difficult it is ahead, he will try to rush forward.
Qingcang picked up the map and looked at it.
Starting from Tongguan, the entire Yellow River became narrower and narrower.
Especially when reaching Hangu Pass, the average width of the entire river channel does not exceed 200 meters.
This is a huge test for him, because if there is Cao Jun guarding near Hangu Pass.
Then, they will control the entire river at a very small cost.
They will stop their progress with extremely small numbers and maximum power.
Regarding how to overcome this problem.
Qing Cang has no initial thoughts yet.
Or wait until you reach Hangu Pass.
Maybe he has some ideas.
Zhou Cang was still waiting for Qingcang's reply.
Seeing that Qin Chang was deep in thought, he asked again: "Commander, look at the smoke, what should we do?"
"I know they lit up the smoke, but we can't stop them.
The smoke has already reached the air, and it's too late to stop them.
As the saying goes, when soldiers come, they will be blocked, and when water comes, the soil will drown them.
When we encounter the enemy, we should make other plans."
It's too early to think about anything now.
Only when you actually encounter the enemy and understand the environment on the spot.
Only then can he make a more accurate judgment.
Seeing this, Zhou Cang didn't know what to say.
He sat quietly on his seat and looked at the scenery around him.
In addition to sighing, he also sighed.
He couldn't even imagine such a speed, but he learned it today.
Who would have thought that it only took one day to reach Tongguan?
Well, this was completely impossible before Hangu Pass is dozens of kilometers away from Tongguan.
Such a distance, with the speed of the swamp air boat, it would take about twenty minutes to reach.
Their journey went smoothly, about twenty minutes later.

They passed the small pass without encountering any obstacles, but they were 500 meters away from Hangu Pass.
The swamp air boat stopped.
Qingcang knew what it meant when the inflatable boat stopped.
It actually meant that there was danger ahead.
It’s so dangerous that even autonomous driving can’t predict it, and you can’t walk.
You can only survive through the numbers in Qingcang's eyes.
Qing Cang was not in a hurry, and immediately picked up the telescope and looked at the Korean troops guarding Hangu Pass.
Hangu Pass is located in Wangduo Village, 15 kilometers north of Lingbao City, Henan Province, and about 75 kilometers away from Sanmenxia City.
It is located on the "Chang'an Ancient Road" and is close to the bank of the Yellow River.
It got its name because it was locked in a canyon and was as deep and dangerous as a letter.
Hangu Pass is located on the plateau to the west, Juejian to the east, Qinling Mountains to the south, and the Yellow River to the north.
It is one of the earliest Xiongguan fortresses built in my country.
It was built in the Spring and Autumn Period and the Warring States Period.
It is the throat of Luoyang in the east and Chang'an in the west.
It is known as "the sky opens in the middle of Hangu Zhuangguan, and thousands of valleys are shocked to the north." " said, it has been a battleground for military strategists since ancient times.
Therefore, it is reasonable for Cao Jun to set up heavy troops at Hangu Pass.
Based on ancient history.
After Cao Cao established Tongguan, he abolished Hangu Pass.
It now seems that since Tongguan was just established, the geographical location of Hangu Pass is still very important.
It can be understood that Cao's army did not all withdraw from Hangu Pass.
No matter what the real historical facts are, they can't break Qing Cang's determination to break through.
In the field of view of the telescope, the entire river has been blocked by a large number of ships.
At the same time, Cao's army was stationed on both sides of the river.
The difficulty of crossing Hangu Pass is much higher than that of Tongguan Pass.
After all, Chongtong Pass used a surprise attack, and Cao Jun was unprepared to rush through the pass.
But it was different at Hangu Pass.
Cao Jun was already prepared, and the pass he had to rush through was much thinner and longer than Tongguan.
When Qingcang arrived at Tongguan in the morning, he took on two tasks.
One was to break through Tongguan, a legendary level of difficulty, which rewarded 80 days of health points.
The second was to break through Hangu Pass, an epic level of difficulty, which rewarded 120 days of health points.
Judging from the difficulty levels of the two, breaking into Han Valley is indeed much more difficult.
If they want to get through with just one ship, it won't be enough to make a leap.
Air ships cannot withstand the bombardment of cannons, especially for well-prepared cannons.
At this time, someone on Cao's defense line looked at the swamp airship and smiled.
"Everyone, get ready, give the passers a good meal.
Set up the cannon and give them a taste of our power."
At this order, a large number of people began to set up cannons.
The formation of Cao's army frightened Zhou Cang into confusion.
Because he knew that the range of the cannon was much more than 500 meters.
They were in an awkward position.
If they fired the cannon.
There were nearly 500 cannons with their barrels facing them.
Once fired.
Then they may be left here forever.
Cao's army at Hangu Pass was much smarter than Tongguan.

Tongguan was more frequently raided, while Hanguguan was more prepared and had more firepower.
And the length of the river they occupy is longer.
The narrow river was full of Cao Jun, layer by layer.
What also made him despair was that there was no mud at all on the edge.
It becomes more difficult for Qingcang to fly over.
If there was silt, it would be impossible for him to pass through the two to three hundred meters long guards.
Cao Jun thought they could stop Qing Cang's actions.
Then they are wrong.
They didn't know that Qing Cang had a heaven-defying existence.
He has a large number of weapon systems and other things.
At this point he already had an idea.
"Since I can't pass the pass by force, I have to find another way to remove all obstacles.
I don't believe it.
There is no way to pass the Hangu Pass."
He made a decision immediately.
So he opened the mall.
His hand began to slide rapidly, while Zhou Cang who was standing by looked dumbfounded, wondering if Qingcang was doing something crazy or not, but he didn't dare to say anything, so he just watched patiently.
Qingcang ignored Zhou Cang and clicked on the mall.
He saw a column with options for transforming an air ship.
He quickly clicked on it.
There was a function that could be transformed into an air submarine.
The points at the back were 90 points.
In other words, he has to spend 90 points to modify his air ship.
“Submarines are interesting, it’s you” He clicked on the options and finally pressed OK. 90 points will be deducted directly.
The entire swamp airship is undergoing transformation at an alarming rate.
It made a clicking sound, as if something was shifting.
"What happened Commander, what happened?"
Zhou Cang's whole person was in a sluggish state.
Originally there were some windows for air transmission and so on.
But at that moment, everything was wrapped, leaving only the window in front of the cab.
In Cao Jun's opinion, this was a strange ship.
There were originally some white beings, but at this moment, the entire ship turned directly into black.
These people looked in panic, what happened to the air ship there?
someone shouted.
"What's going on?
What's going on with the ship?
He's changing colors."
"It must be blessed by gods."
"Who are the people in the boat?"
"It's terrible."
Some people are on the edge of their seats because they have never seen anything like this.
This is far more terrifying than that.
Suddenly the whole black ship slowly sank, yes it was sinking.
After just a while, it disappeared from Cao Jun's sight.
Cao Jun didn't know, and Zhou Cang didn't know either.

What happened?
Especially Cao Jun and the others shouted: "The ship has sunk, it has sunk" The boat is gone.
So where should they hit.
A so-called general here shouted: "If you want to see people alive, you will see corpses if they die.
Come here.
Send out a diving team.
Then I will fish them out."
There were five or six hundred people here jumping into the Yellow River.
They were all people with excellent water skills.
They swam desperately to the place where Qing Cang disappeared. at the same time.
Zhou Cang was also very frightened in the boat.
He shouted: "Commander, the ship is sinking.
Commander, you go first.
Commander, hurry up."
I have to say that his loyalty is quite high, under such unknown circumstances.
He could let Qing Cang go first.
Qingcang smiled: "It's okay.
Look, if we sink, there won't be any water coming in.
There won't be any danger."
"This is" "Now, it's not called an airship.
You can call it a submarine."
"submarine"
"For you, it can be understood as a boat moving in the water."
Zhou Cang seemed to understand but Qingcang didn't pay attention to him anymore.
Although it is a submarine, it is very simple.
Not like modern submarines.
The system only made some airtight modifications to the swamp air boat, and the fan at the back was still retained.
At the same time, the fan also becomes a propeller.
It also improves some of the sinking functionality.
Qingcang doesn't have high requirements, as long as it can be used, it doesn't matter what its function is.
The water in the Yellow River is very turbid.
Looking through the glass, it looks gray and yellow.
The water is full of yellow silt.
Yellow water is not good for vision.
But this does not seem to affect the submarine's walking, because it also has a set of automatic driving functions.
"We're leaving."
Qingcang pressed the autopilot mode, and the air submarine began to move forward.
He said: "This submarine can't last longer than half a stick of incense, so we must get out of the water before half the stick of incense burns out."
Because these modifications are only temporary, it cannot stay in the water for a long time, and the oxygen inside is not very sufficient, so they must come out for air every once in a while.
But half a stick of incense is enough time.
Enough for them to survive Cao Jun's blockade.
The Yellow River was flowing rapidly, and a large number of Cao's troops rushed into the Yellow River.
They try to find out what happened to the submarine.
But the submarine disappeared as soon as it entered the water, and no matter how hard they searched, they couldn't find it.
They changed four or five groups of people, but could not find the whereabouts of the submarine.

Someone shouted: "There is no way we can find the whereabouts of the ship."
"It's like they suddenly disappeared, just disappeared."
As soon as this was said, no one believed it, because they clearly saw that the submarine had indeed sunk to the bottom of the water, only in their eyes.
When more than 10,000 people saw this scene, how could they just say no and be gone?
Little did they know that Qing Cang was already heading downstream under their noses.
Fortunately, the water here is quite deep.
If it were shallow water, they might be trapped here.
The leader here suddenly shouted.
"We must fish them out no matter what.
You all have to go into the water.
I will conduct a large-scale search from here to ten miles down.
I must find the ship.
Even if I dig the ground three times, I will still find them."
Come."
He didn't believe that Qingcang just disappeared.
But indeed he has disappeared.
He ordered nearly ten thousand people to go into the water to find Qingcang.
Everything that happened above had nothing to do with Qing Cang below, but one person was very excited, and that was Zhou Cang.
He hadn't seen anything like this.
I feel very novel.
"It's really amazing that this boat can still swim in the water.
Commander, you are really a god.
Apart from being a god, I really can't find any other words to describe Qing Cang."
Yes, Qingcang is a god in their eyes.
An invincible god-man, today he once again refreshed Zhou Cang's knowledge.
Qing Cang didn't taboo too many things.
Anyway, Zhou Cang knew it, so it didn't matter.
This swamp air submarine walked for about ten minutes.
Just now it slowly emerged from the water.
They had already pushed Cao Jun far behind.
Cao's army upstream was already completely busy, looking for the whereabouts of Qing Cang and others.
But how could they find them if they were searching like this?
Even if the Yellow River water was drained, it would be impossible to find them, because they had already left here and headed downstream.
At the same time, they will not release the smoke until they find the airship, because they cannot be sure where they have gone and who the smoke is for.
This also gave Qing Cang and the two men temporary safety, and they would not be unduly targeted by Cao Jun.
In this way, you can easily cross Hangu Pass.
An epic mission was completed just like that, and 120 days of health were obtained.
He clicked quickly.
Because there is a task completion reminder.
He pressed two tasks.
After clicking the button, he gained a total of 200 days of health.
Deduct 90 days and modify the health value.
He made a huge profit this time for 110 days.
There are two more passes to pass, one is Sishui Pass and the other is Guandu.
Sishui Pass is about 170 kilometers away from him, and it takes nearly two hours to reach it.

Now he has passed two relatively difficult passes, Sishui Pass
The difficulty should not be great.
Once you safely cross Sishui Pass, Guandu can be reached in no time
