To be honest, Gao Jie's soldiers were not optimistic about using gunpowder to blow up the city wall.
Although black powder can be ignited as a boost, the real power is the cannonballs and marbles.
It was common practice to bombard city walls with heavy artillery, but it was unheard of to directly use gunpowder to blow up the city.
However, Gao Jie is their commander-in-chief, so the soldiers will naturally not question their commander's orders.
It's just that more people are looking forward to the development of the situation with a spectator mentality.
Jin Yuhe on the top of the city was even more confused by the enchantment array set up by the Ming army.
Digging more than a dozen tunnels at the same time, the Ming army wanted to take a multi-pronged approach But the problem is that it takes a long time to dig tunnels.
It can easily take a month.
How much energy does it take to dig more than a dozen tunnels at the same time?
How could the Ming army launch a frontal attack under such circumstances?
In the final analysis, hole attack is only an auxiliary method, and it often achieves miraculous results when combined with frontal force attack.
But if you give up the frontal attack and rely solely on acupoint attacks, you will be easily targeted.
Logically speaking, Gao Jie can be considered a general, but he doesn't understand such a simple truth.
Jin Yuhe couldn't figure it out and simply stopped thinking about it.
Anyway, the more stupid tricks Gao Jie made, the better it would be for Jin Yuhe.
The small mounds piled up by the Ming army were not far from the city wall, so Jin Yuhe could clearly see the movements of the Ming army soldiers.
He saw the soldiers of the Ming army carrying the coffin into the tunnel, and thought that they must be trying to hollow out the city foundation, use the coffin to support it, and then burn the coffin with fire to cause the city foundation to collapse.
But is the coffin a bit too big?
Generally, this effect can be achieved using only wooden piles.
And there is no need to transport the coffin in so early.
Jin Yuhe immediately ordered the soldiers stationed inside the city wall to be on standby at any time.
As soon as the soldiers in the water tank heard the noise, they would divert water into the tunnel and drown the bright dogs.
However, what Jin Yuhe found difficult to understand was that these Ming soldiers evacuated one after another shortly after carrying the coffin into the tunnel.
Jin Yuhe's eyes were as wide as cowbells, and he couldn't believe what he saw.
As far as he knew, it would take at least ten days and a half to completely excavate the city foundation.
The Ming army only spent two or three days digging tunnels.
How could it be possible to excavate the city foundation if the tunnel was dug so shallowly?
Even if Gao Jie is old and confused, don't the other generals in his army know how to give him some advice?
Before Jin Yuhe could laugh at Gao Jie's stupidity, he heard a loud boom.
The ground seemed to tremble, stones and rubble flew, and smoke and dust rose up, making people look gray and gray.
Jin Yuhe was choked and coughed, and lay on the ground under the protection of his soldiers.
After a while, when the smoke and dust dissipated slightly, he stood up shakily.
Could it be that the ground just shook?
Although Jin Yuhe has not personally experienced earthquakes, he has heard stories from the elderly.
It is said that when an earthquake occurs, the ground will completely crack, and whether it is a simple house where ordinary people live, or a mansion full of carved beams and paintings of princes and generals, they will all collapse.
The scene just now was so similar to what it looked like during the earthquake.
"General Jin, look, the city wall has collapsed."
A soldier with sharp eyes saw through the smoke and dust a huge gap in the city wall more than ten steps away.
The gap was three feet wide.
This section of the city wall collapsed inward.
Although it did not completely collapse, there was a slope for soldiers to charge.
Jin Yuhe was shocked.
If the Ming army used this sudden slope to launch a charge, it would be difficult for the Green Camp Army under his command to withstand it.
"Quick, go to the gap and repair an inner wall."
The only solution for now is to build an inner wall before the Ming army launches its charge.

This temporarily built inner wall is definitely not as strong as the city wall itself, but it is better than nothing, and it can always cause some difficulties to the charging Ming army.
Amid Jin Yuhe's roar, the green battalion soldiers of the Qing army drove their strong men to the gap to build the inner wall.
They had just arrived at the gap, and before they had time to move the rocks and giant trees, they heard another loud roar.
Immediately afterwards, the ground trembled, stones and sand flew, and smoke and dust rolled up and filled people's eyes and mouths.
It's exactly the same as the scene just now The green camp soldiers and strong men were frightened and fell down one after another holding their heads.
When they were able to open their eyes, they found another gap in the city wall about one hundred and fifty steps away to the east.
Jin Yuhe's face on top of the city was already pale.
Before he could give instructions, he heard loud noises one after another.
In less than half a stick of incense, there were more than a dozen loud noises.
The ground trembled with each sound, followed by bricks and rubble flying and yellow dust billowing.
After all this, a huge gap will appear on the city wall.
After all this was over, at least two or three gaps appeared on every wall of Kaifeng City.
Although it was not riddled with holes, it was still very scary.
"What the hell is this?"
Jin Yu and Zhi were furious.
He refused to accept it.
If Gao Jie hadn't been lucky for three or two months, he wouldn't have had the chance to capture Kaifeng City.
But after this series of earthquakes, the majestic Kaifeng City seemed to have turned into a little lady wearing only a thin veil.
Facing a strong man like a wolf and a tiger, wouldn't it be like being crushed under her?
Could it be that God wants to kill me?
Jin Yuhe gritted his teeth and was still ready to fight to the death.
The trapped beast is still fighting, he must not give in so easily.
Jin Yuhe's ability to command on the battlefield is still very strong.
Under his command, 30,000 Green Battalion soldiers were divided equally to guard every gap.
There is definitely no time to build the inner wall now, but the city wall has not completely collapsed, and the green battalion soldiers can still have a certain advantage in the city.
Although there are more than a dozen gaps, each one is not particularly wide, and one or two thousand people are enough to guard it.
Gradually, Jin Yuhe also calmed down.
He found that the situation was not so bad that he could not control it, and he did not need to rush to kill himself with a knife.
What surprised Jin Yuhe even more was that the Ming army did not seem to be in a hurry to launch an offensive.
This gave Jin Yuhe ample time to deploy his troops.
In the large tent of the Ming army not far away, Gao Jie was also stunned with surprise.
"Your mother, the gunpowder in the coffin is so powerful."
He first ordered the soldiers to dig a tunnel and send coffins filled with gunpowder into the tunnel to bury them just for show and to make the emperor look good.
In his opinion, a coffin of gunpowder could not shake the solid city foundation.
Who would have thought that after igniting the fuse, dozens of loud noises would be heard one after another, and the whole city of Kaifeng would feel like the sky was falling and the earth was falling.
After the yellow dust dispersed, more than a dozen gaps appeared on the walls of Kaifeng City, announcing the success of the improved hole attack.
However, Gao Jie was not mentally prepared at all, so he did not immediately order the soldiers to attack after the city wall was blown down.
It was Li Chengdong who stepped forward and reminded: "Commander, please give the order to attack the city
