The white light flashed in Xiao Yu's hand, and there was a black suitcase.

He put the suitcase on the ground, opened it, and took out a few small pieces of very well wrapped Type B explosives, which were very stable and could be detonated normally even in the rain.

When he was in the training base, Xiao Yu and Li Qiang had simply learned the knowledge of installing and detonating explosives, and they were naturally not a problem for this kind of simple work similar to opening the mountain.

Looking at the mountain wall in front of him, Xiao Yu's divine sense immediately probed over, like an X-ray perspective machine, and saw through the specific thickness of the mountain wall.

His Xuantian Lu had broken through to the second layer since he fused the 'Foundation Building True Essence', and his divine sense was much stronger than before, and he could already cultivate one or two secret methods of divine attack recorded in the Xuantian Lu, and it was naturally easy to detect the thickness of this mountain wall.

Xiao Yu's eyes flashed, his brain was running rapidly, and he suddenly calculated several optimal tipping points for placing explosives.

He took out the dragon and tiger three-section stick from the storage bag, opened it, and hit it hard more than a dozen times, and the solid mountain wall was beaten to stone chips, and several small pits immediately appeared.

Xiao Yu used the dragon and tiger three-section stick as a drill pipe to come in handy, put one end of the three-section stick on the small pit, and the stick head was wrapped with a thick layer of heaven and earth vitality as a drill bit, and used his divine sense to urge the heaven and earth vitality to rotate quickly, and after a while, he drilled several small holes that were a foot deep.

Carefully put the explosives in and set up the detonator.

Everything was ready, Xiao Yu dodged far away and pressed the button of the wireless detonator in his hand.

I only heard a loud 'boom', as if a thunderclap sounded in the sky, a large piece of mountain rock was blown away, and a swarthy hole was exposed in front of Xiao Yu.

"Sure enough, it's here!"

Seeing this swarthy hole, Xiao Yu's head slammed to the ground, as if something had suddenly exploded in his head, and his head was splitting.

He walked towards the mouth of the cave in despair, and he knew that there must be a long passage in the hole, and at the end of the tunnel was a gate made of stainless steel that was more than two feet thick.

That gate separates life and death into two worlds.

The moment he stepped into the cave, Xiao Yu tore a 'ghost light talisman' in half, and a hazy ghost light lit up, illuminating a radius of five or six meters around Xiao Yu.

To Xiaoyu's surprise, this dark light is bright but not dazzling, and the lighting effect is very good.

Xiao Yu touched the stone wall of this road as he walked, and a familiar and unfamiliar feeling arose, and he even found the marks left on the stone wall by himself with a knife before.

Along the way, although this road is only more than 100 meters, it feels like a whole century to Xiaoyu.

All the memories of this road were all connected, ten years, a whole ten years, Xiao Yu counted the carvings on the stone wall, and burst into tears.

Ten years of spring, summer, autumn and winter, ten years of flowers falling and blooming, Xiao Yu can't believe that he has actually stayed in this dark underground base for ten years, if it is not for the 'shadow' to sneak out of the base with him occasionally and play in this valley, God knows, he will not become a madman.

He didn't know how Shadow got the code to open the door, and to him, Shadow was both intimate and mysterious.

Sometimes, they had fantasized about whether they could escape from the valley, but they also knew that it was only a matter of thinking, and that at the cave leading to the valley, there were twenty or thirty well-trained guards guarding them 24 hours a day, armed with guns, and if anyone left the valley, they would be killed.

Unconsciously, Xiao Yu had come to the stainless steel gate, which may have undergone some kind of special treatment, and in the humid environment of the corridor, there was not a single rust spot on the whole body.

Xiao Yu's heart beat violently, and he knew that as long as he opened this door, the underground base he had been looking for for a long time would appear in front of his eyes.

There is a cipher plate on the door, and the small red light on it is still on, as long as you enter the code to open the door, you can open the door.

However, how could Xiaoyu know what password? When I sneaked out with Shadow, Shadow entered the password to open the door.

Looking at this heavy door, an irrepressible anger rose from Xiaoyu's heart, and it was it that blocked himself and the 'shadow' back then.

With a clear drink, Xiao Yu's right fist had already slammed into the gate, and the gate did not move at all.

Xiao Yu was furious.

"Gather your strength!"

The Heaven and Earth Yuan Qi in the Yongdao frantically converged towards Xiao Yu, and in a few seconds, Xiao Yu's momentum reached its peak.

"Seven Illusions of Fiction and Reality!"

Xiao Yu's right fist was wrapped in a thick cloud of heaven and earth vitality, and he slammed towards the gate fiercely, and the powerful energy that exploded when he punched out made several terrifying sonic booms in the air.

This is the most powerful killing move that Xiao Yu can perform at present, and this is also the biggest gain in the battle with the old guy of the White Bone Gate yesterday.

At that time, the 'Seven Illusions of Void and Reality' were displayed only after the addition of 'Blood Evil' and 'Gathering Qi', and the body's functions were greatly improved.

And now, Xiao Yu can perform the 'Seven Illusions of Reality and Reality' with only the 'Gathering Qi Decision', which shows that after his successful foundation building, his physical fitness has also been greatly improved.

'Bang! A loud bang sounded in the corridor, and the energy wave formed by the Heaven and Earth Yuan Qi after the violent impact was like a shock wave after the explosion of a bomb, stirring in all directions in the corridor.

There was only a tiny dimple on the surface where the stainless steel gate and the fist met, and there was no sign of collapse at all.

'Bang! Bang! Xiao Yu slammed into the 'Seven Illusions of Reality and Reality' with two more fists, and except for two more small depressions on the door, he still didn't move, as if mocking Xiao Yu's ignorance.

When the power of 'Gathering Qi Decision' dissipated, Xiao Yu's anger was also vented with these punches, and he couldn't help but curse himself in his heart, what is the strength of a big living person and a dead thing?

However, he was also shocked by the power of his punches, after the Heaven and Earth Yuan Qi replaced the internal force, the power of the virtual and real changes greatly increased, and the increase was almost five times that of before!

No wonder, Lao Li Tou once said that a second-order body refiner can compete with a cultivator in the foundation building period, this sentence is not groundless, it is stronger than King Kong's body, plus the assistance of heaven and earth vitality, this kind of physical attack power is really too amazing.

However, even though the alchemist's physical attacks were very powerful, it was useless to deal with such a two-foot-thick steel gate.

Xiao Yu stopped doing anything, took out the black suitcase, and glued all the Type B explosives inside to the door.

After installing the detonating device, Xiao Yu withdrew from the corridor, he knew that the power of this explosion was absolutely extraordinary, and he still had to be careful.

Pressed the blast button, a muffled sound came from inside the corridor, Xiao Yu felt the earth as if it trembled violently, and after waiting for a while, a compelling qi Lang erupted from the mouth of the Yongdao, along with the qi Lang, as well as several large stones at the entrance of the cave.

Entering the Yongdao again, Xiao Yu couldn't help but be a little worried about whether the strong explosion just now would collapse the entire Yongdao. Although he had calculated in detail the angle at which the energy would be released after the explosion when he placed the explosives, he could not guarantee that the calculations would not be biased.

Worried along the way, when he came to the stainless steel gate, Xiao Yu finally relieved himself, the stainless steel gate had been blown up and fell inside, and the mountain wall of the Yongdao was basically not damaged except for some gravel.

The entrance to the underground base was already naked in front of Xiao Yu.

According to the excitement, stepping through the gate, Xiao Yu walked slowly, to Xiao Yu's surprise, the entrance was very clean, and there was no scene of corpses everywhere as he imagined.

Xiao Yu couldn't help but wonder in his heart, what is going on? Could it be that the bloody killing night of your dream was not real? However, this underground base and this stainless steel gate really exist.

The light of the 'ghostly light charm' illuminated a button-like thing on the wall, Xiao Yu's heart moved, he reached out and pressed it, and there was a 'buzz' sound, as if he had touched some switch, and a large piece of silver-white light sprinkled down from the top of his head, illuminating the entire entrance.

Xiao Yu found that this underground base seemed to be built entirely of a silver-white metal, which was not the same as the material of the steel gate, and it looked like it was a little harder than the steel gate, and the steel gate was obviously installed later.

Walking along the corridor at the entrance, a feeling of familiarity and familiarity flooded through Xiao Yu's heart.

The underground base is very large, like a labyrinth, but for Xiao Yu, it seems to be a familiar road, and even the elevator to the next floor can be easily found.

In this underground base, every place he went, every time he touched something, there was an extra memory fragment in his mind.

These memory fragments flew and circled in his mind, and some related memory fragments were combined in pairs to form a larger memory fragment, and these larger memory fragments were constantly combined with other memory fragments, and Xiao Yu's memory was recovering at an alarming speed.

"This is where the mecha is stored, and I remember, my 'Hami' mecha is stored here!"

At this time, Xiao Yu was standing in a huge training ground, which was about twenty meters high, surrounded by forty or fifty small rooms, and in Xiao Yu's memory, these small rooms stored mecha of different sizes and styles.

Xiao Yu's first 'Yumi' type mecha was stored in the second room from the left, and the only 'God of Killing' was stored in the innermost room, which was the only room in the entire training ground with a combination lock, and no one could enter except for a limited number of people.

But now, the doors of these rooms are all open, and there is no trace of any mecha in sight, not even the room where the 'God of Killing' is placed.

Xiao Yu felt that his head was uncomfortably swollen, although his memory was recovering little by little, but the scene in front of him made him puzzled.

When he was at the base, there were no less than 30 boys who learned to control mecha with him, and every day in this training ground, more than 20 mecha ran back and forth, and the scene was extremely lively.

The place where Xiao Yu toddled in his first 'Hami' mecha was also here, and he remembered that he was the slowest among the boys, and when those boys could drive the 'Blue Shadow' mecha, he couldn't even control the 'Hami' proficiently.

And when they tried to control the 'Green Shadow', they were already able to drive the 'Moon' all over the field.

But now, these people seem to have disappeared mysteriously, and anything that can give Xiao Yu clues has also disappeared mysteriously, for Xiao Yu, even seeing the skeletons all over the ground is much better than looking at this empty field.

Although Xiao Yu was not on the right path with those boys in the past and was often bullied by them, at this moment, he wished to be able to meet one of them and inquire in detail about the ins and outs of the matter.

"Anyone? Anyone?!! ”

Xiao Yu shouted loudly as he walked, hoping to find a survivor in this closed underground base, but these efforts were all in vain, and the entire underground base was like a dead city, without half a life.
