"Under the Ice Peak?" Yang Yi's eyes suddenly rolled, and he suddenly came to his senses, "The four ice peaks are connected to the four points of a square, and such a standard square building like a measurement can only be established by a cultivator." ”

While muttering to himself, Yang Yi recalled the locations of the four ice peaks in his mind, and connected them with threads. Match it with the length it deserves.

Could this be ......

Suddenly, as if he remembered something, Yang Yi immediately connected the files of the underground top-secret base of the Demigod Academy.

Top Secret Base No. 1, a top-secret base deep into the deepest part of the earth.

Yang Yi immediately made a major discovery, the range of these four ice peaks is exactly the same as the range of the No. 1 top-secret base in the Lost Land in the top secret archives of the Demigod Academy, and Yang Yi had explored the construction materials of all the territories before establishing his own territory, and he found that no matter how huge the underground base of the cultivator is, as long as it does not go deep into the water, there will be more than four emergency ventilation pipes, perhaps because the cultivator is too dependent on oxygen, or maybe it is to be prepared for danger in times of peace, this design has been passed down and has almost become a symbol of the cultivator's territory。

Wouldn't the four ice peaks happen to be four ventilation ducts, and the Demitheon Academy was indeed very clever in sealing the territory and closing all four ventilation ducts at the same time, sealing all possible entrances and exits, and building the best identification signs to facilitate opening in the future.

"The monster doesn't even keep a record of the exact location of the demithet's secret documents. Yang Yi muttered to himself as he smiled, knowing that the demigod academy was not a rule, and it would not be difficult to find any closed top-secret base in the future.

Three hours, if it is usually blinked, it will pass, but at this time Yang Yi is anxious, after all, he has just been attacked, if there is another assassin at this time, Yang Yi has no other way but to wait for death.

Fortunately, Yang Yi's worries did not happen, and for three hours, there was no sound except for the howling cold wind, and even the demon beasts seemed to be extinct, and not a single one appeared.

Activating Yangyi, Yangyi quickly came to the collapsed ice peak.

Despite the collapse, the ice peak still covers a vast area, and Yang Yi stands on it as small as an ant.

But with the help of the little jellyfish, Yang Yi quickly found the location of the vent, and it was here that the little thing entered the territory.

Enduring the severe pain in his body, Yang Yi's mind moved, and his true qi burst out of his body to form claws in an instant, which was temporarily used as a digging tool.

After a few claws, a stone-sealed passage appeared in front of Yang Yi.

The vent is very large, at least there is no problem for Yang Yi to enter, but at the vent, there is still a heavy stone door tightly closed, here is different from the main entrance, here there is not even a handle, it is completely open inside.

However, everything is difficult to Yangyi, he has a top-grade flying sword, and there is an indestructible top-grade flying sword.

The flying sword quickly pierced into the stone gate, and in front of Yang Yi, the hard stone gate was like a piece of bread, and each sword would bring up some crumbs.

The stone gate is five meters thick, and it may take a long time to completely open it with a flying sword, but at this time, Yang Yi has no choice, if he wants to recover, if he wants to escape the pursuit of one after another, he must enter the territory.

The special environment in the Lost Land made it impossible for Yang Yi to work for a long time, two hours, Yang Yi and himself insisted on two hours at most, and then had to rest for up to three hours.

However, Yang Yi has been comforting himself, after all, victory is in sight, and he can only speed up himself.

The iron pestle was sharpened into a needle, and Yang Yi was busy for a day before the stone door was opened in its entirety.

All the Shenyuan was released, and Yang Yi slowly fell downward, monitoring every move of the ventilation passage at any time.

At this time, as long as a territory guardian circle is opened, Yang Yi has no hope of escaping.

landed quickly, for two hours, just when Yang Yi's patience was about to wear off, his feet finally fell firmly to the ground,

Pushing open the thick stone gate that was hidden, Yang Yi sighed happily, if there is still a stone gate here, then Yang Yi will welcome another day of hardship.

Entering the stone gate happened to be a warehouse, and through the warehouse, the scale of the passage suddenly became smaller.

Shen Yuan didn't have any signs, but Yang Yi suddenly felt uneasy, and simply took out a pair of icicles from the Ice Splitting Demon Beast again.

The passage connects the various rooms of the underground base, but in such a large territory, the complexity of the passage is unimaginable, and without the help of an accurate topographic map, it can be said that it is impossible to find a place to heal with your feet alone.

Yang Yi didn't want to walk through the underground base with his feet, he wanted to find the nearest room and look for the structural diagram of the underground base.

Having made up his mind, Yang Yi quickly walked towards the passage.

Without strong external stimuli, the top-secret base that has been completely closed will not have any guardian arrays, which is also the most reassuring thing for Yangyi.

"Boss, that little thing is not far from here. "The little jellyfish has never stopped monitoring small things, and the Shenyuan of their own Shenyuan silk thread can even be accurate to centimeters.

Ten minutes away, Yang Yi saw a fork in the road, and according to the hint of the little jellyfish, where is the place where the little thing is.

Being able to catch small things and find topographic maps at the same time, Yang Yi will certainly not give up on things that kill two birds with one stone.

Walking forward quickly, at this time, the true qi in Yang Yi's body had basically recovered, and the severe pain in his left arm and his whole body had also been reduced a lot.

In the Territory Passage, each fork in the road is a separate space, perhaps the size of a small town.

As soon as he turned the corner, a breath of death rushed towards him, Yang Yi suddenly transported the true qi in his body to wrap his whole body, and with a movement of his mind, the true qi surged, and the silver claws also appeared on his right hand.

One-minute, two-minute, three-minute......

Five minutes passed, and the breath of death continued to be heard, but there was still no sound in the darkness at the end of the passage.

Walking forward slowly, Yang Yi bent down slightly, the claw of his right hand placed in front of him, ready to attack or retreat at any time.

The passage is getting wider and wider, and gradually Yang Yi can't even perceive the walls on both sides, and the front is even more ethereal, Yang Yi's Shenyuan is only within a hundred meters, and Yang Yi has not found any objects within this hundred meters.

At this time, Yang Yi was already completely confused, as long as he took any wrong step, the half-hour journey might be in vain, and he would return to the passage again and explore again.

But thanks to the little jellyfish, with his divine element for small things, Yang Yi believes that he will be able to find something.

Walking forward vigilantly, Yang Yi did not dare to relax a step.
