Once you find the general direction, the next thing will be easier. .
Li Yao, Long Yangjun, Li Jialing, plus the two newly born "information beings", and of course the two little guys' toys, the ultra-miniature psychic puppets as small as ants and the wild bee-shaped ones that can fly freely.
The psychic puppet set out immediately, exploring along the existing cracks and mines in the direction of the special ripples.
Every three hours, stop and start the "vibration ripple scanning and grabbing magic weapon" again to relocate the source of the vibration.
Sure enough, the ripples became stronger and clearer, indicating that their direction was not wrong.
According to the increasing series of ripples, the direction and height could be further fine-tuned.
Gradually, they left the towns where ordinary people gathered underground.
Those areas rich in spiritual energy and life were far away, and they really entered the absolute darkness of "darkness and dead silence".
This is a life restricted area where even underground savages have no access.
Tunnels and mines have gradually become narrower and cut off.
Only strange-shaped natural cracks can allow people to barely pass through.
In many places, it is even necessary to use giant divine soldiers to forcibly clear the way to find new cracks.
If it weren't for the two super masters Li Yao and Long Yangjun who were at the front, consuming spiritual energy at all costs, and running so recklessly, they would never have been able to find the right path, and they would have been trapped alive in the rock formations.
In this way, they held their breath and sneaked in the darkness for more than twenty-four hours, and finally saw a glimmer of light.
Using the bone-shrinking technique to shrink the body to the limit, and after struggling to get through a natural crack that was not much thicker than a poisonous snake, the front suddenly opened up, but it was an artificial tunnel with a diameter of at least thirty to fifty meters, and it was so dark that it was unknown where it led.
This tunnel is wide on both sides and narrow on the top and bottom, and is oval in shape.
The surrounding rock walls can clearly show traces of artificial excavation.
However, after tens of millions of years of erosion, it has gradually become smooth, as if wrapped in a hard slurry shell. .
"This tunnel was not dug now."
Li Yao analyzed the height at this moment through the barometer, "We have descended to more than 24,000 meters underground.
In many places, this is the dividing line between the crust and the mantle.
I didn't expect that there is a scale at such a deep distance.
Such a huge artificial tunnel exists.
"Come over and look at the traces on the rock walls on both sides of the tunnel.
It's best to reach out and feel it.
Do you feel if there are any fine spiral lines?
Those should be traces excavated by some kind of shield machine or giant drill.
Judging from the size of the traces, From the looks of it, it doesn’t look like the same type of magic weapon from the Pangu or Nuwa tribe is too small.”
Long Yangjun was the first to understand what Li Yao meant.
Most of the thirteen member races of the Pangu Civilization Alliance are huge carbon-based life forms.
They are often twenty to thirty meters tall or even higher, making them towering giants.
Therefore, if the shield machine, excavator, crusher, etc. of the Pangu or Nuwa tribe should be larger in size, then the size of the traces excavated should also be much wider.
In many prehistoric ruins, including the Kunlun Secret Realm, the remains of similar magic weapons from the Pangu and Nuwa tribes have been unearthed, so both Li Yao and Long Yangjun knew the dimensions of similar magic weapons very well.
"Do you suspect that this artificial tunnel was dug by humans?"
Long Yangjun thought for a while and said, "It's the emperor or the Son of Blood God from ten thousand years ago!"
"If your guess is correct, then it is very possible."
Li Yao nodded and said, "Assuming that the army of the Emperor and the Son of the Blood God is really looking for something under the Tianji Star, it is natural to dig a sufficiently spacious artificial tunnel to transport a large number of troops and even destructive magic weapons in, and the Black Star Now that Emperor Wu Yingqi knows this secret, there is no need to foolishly build his own tunnel from scratch.
As long as he finds the tunnel used by the emperor or the Blood God Son, he can easily reach the 'target'."
"That makes sense."
Long Yangjun released his spiritual thoughts to explore for a moment, then led everyone to the middle of the tunnel, pointed at the indentations on the ground and said, "Come and touch this."
Li Yao knelt on one knee and carefully rubbed the uneven ground, feeling countless jagged bumps.
"It's crawler tracks, very, very wide, heavy-duty tracks, and there are six of them in a group.
It's some kind of crawler-type transport vehicle with an astonishing load capacity."
Li Yao said, "If it were ten thousand years ago, the army of the Emperor or the Son of Blood God would have crushed them, the traces would have been eroded by time long ago, and they would never be so 'fresh'.
The traces of these tracks were within the last year and a half." , it was left after repeated crushing!”

Now, they were finally sure that their judgment was correct.
As for the height of the tunnel, which is only thirty to fifty meters, but the diameter of the working surface of the super giant shield machine is hundreds of meters, this obvious "contradiction" is not a big problem.
The super-giant shield machine, a steel behemoth that seems to be unparalleled, is extremely fragile on the other hand.
The ultra-high-speed operation time is measured in seconds.
If it is not necessary, it can take one second less to start.
One second.
It is the most efficient way to break down the super giant shield machine into thousands or even tens of thousands of components and magic units, transport them to the work site through crawler-type load-bearing vehicles, and then assemble them on-site for use.
Knowing that this artificial tunnel must lead to Black Star Emperor Wu Yingqi's "trump card", then, after continuing to hold his breath and sneak for more than two hours, he heard the vague "rumbling" roar of hundreds of thousands of waterfalls coming from the front, It was not surprising at all to see groups of Royal Guards armed to the teeth.
Not to mention Li Yao and Long Yangjun, even Li Jialing, a little golden retriever who had just completed a course of strengthening treatment, could easily defeat these imperial guards.
But there was no need to alert others in this way, and they chose a safer approach.
Everyone was hibernating in the dark corner of the artificial tunnel.
Li Yao used the "Fierce Dragon" to drill a small hole as thick as a finger in the rock wall, leading directly to the busy work site ahead.
Then Li Xiaoming and Li Wenwen controlled a large number of mechanical ants, following the Climb all the way through the small hole and send back the scanned images and ripples, so that everyone can share the vision of these mechanical ants.
The images transmitted back by the Xiaolong and the Mechanical Ant made their breathing stagnant and they almost didn't scream in surprise.
The underground space at the end of the artificial tunnel is too huge, too vast, and too "vast".
Li Yao has seen countless huge underground spaces, including initially seeing a silver "ocean" underground on the Skeleton Dragon Star.
But all the underground spaces combined are not as shocking as the void in front of you.
The diameter and height of this underground space are at least ten times that of the large iron factory, and can accommodate dozens of underground towns.
It is like a miniature black hole embedded inside the Tianji Star, constantly swallowing up all the surrounding rock formations.
Looking around, the surroundings are covered with spiral staircases and platforms, as well as huge caves that are opened horizontally on the rock wall, like some kind of intricately constructed honeycombs and ant nests.
Some "ant nests" are the barracks of the Royal Guards.
Next to the barracks, interlocking crystal cannon positions and various three-dimensional defense systems are set up, which can be described in four words as "water cannot enter"; other "honeycombs" are assembled and The factories that repair TBMs are all large in scale.
Li Yao controlled the Xiaolong and carefully adjusted its direction.
All the way down, he saw that on the platform near the bottom of the huge cavity, there were indeed several super-giant shield machines that were digging and crushing non-stop.
There were also people around them.
Following hundreds of large, medium and small shield machines, the contrasting shapes are like giant beasts hunting with their children.
It is absolutely impossible to open up such a vast underground space in just one and a half years with just these few shield machines!
Li Yao's mind was spinning, and then he stopped laughing, laughing that he was too stupid.
Of course, such a "vast and boundless" space was not dug by Black Star Emperor Wu Yingqi alone.
In all likelihood, as Long Yangjun said, it was the emperor or the Son of the Blood God.
The troops dug out, Wu Yingqi just inherited the work of his ancestors and continued to dig. boom!
boom!
boom!
Boom boom boom!
At this moment, they heard very regular explosions coming from deep in the underground space.
"Are they firing cannons to crush rock formations?"
Long Yangjun asked Li Yao in a low voice.
"no."
Li Yao put his ears and cheeks against the rock wall, felt it carefully for a moment, shook his head and said, "We use the ripples and feedback released after the crystal bomb explodes to scan the structures deeper underground."
This method of holographic scanning using ripple feedback is a conventional method for underground exploration.
Judging from the layout of the corrugated emission source, the cultivators first used a super giant shield machine to dig out a relatively shallow tunnel in all directions underground, spreading it out in a radial pattern, and then installed a set of special crystals at the end of each tunnel.
Use stone bombs to scan the sky like a "net all over the sky".
In other words, no matter what Wu Yingqi asked them to look for, there was no breakthrough yet, they were just firing shots aimlessly.
Upon discovering this, Li Yao breathed a sigh of relief.
"At least a whole regiment of Imperial Guards has been deployed here, and judging from the fact that they are constantly building new barracks and fortresses, the size of the garrison will continue to expand."

Li Yao narrowed his eyes and carefully analyzed the ultra-clear images sent back by the Xiaolong, "No wonder Li Linghai attaches so much importance to the Imperial Guards.
He has been flirting with and secretly colluding with the Imperial Guards for a long time.
Let me just say that most of the Imperial Guards have no fighting ability.
The battlefield is full of soldiers and generals who are on the verge of collapse.
No matter how loyal they are, recruiting them will not be of much use.
"It turns out that Li Linghai or Wu Yingqi had no intention of letting the Royal Forest Army go into battle to kill the enemy, but they used them as 'engineers'.
This is quite appropriate."
Li Yao scanned around and found no trace of any masters within his sight range.
His heart moved and he said with a smile: "What do you think will happen if we suddenly rush down and kill a guy?"
