Li Xingyuan had successfully built the foundation, and slowly stood up, feeling that his eyes and ears were so clear for the first time.

Aura, this indescribable and incomprehensible thing that cannot be understood by any known science, circulates in Li Xingyuan's brand-new meridian network, unlike the artificial nerves made by polyethoxythiophene, the artificial meridians bring Li Xingyuan a complete kind of life type improvement, whether it is strength, speed, or something else - he looked at the Optimus Hand, which was shrouded in a layer of white light, which was echoing the aura in Li Xingyuan's body.

Thinking about what happened a day ago now is like a world away.

After Li Xingyuan sighed, he saw the corpse of the old man in Mai on the side, his eyes were complicated, if the old man in Mai hadn't come to the door at the beginning, he would not have had the opportunity to get the immortal, and if there was no old man in Mai or any of the people in the walker's release, he might not have the possibility of leaving, thinking of this, he flattened the body of the old man in Mai, and saw the old man in Mai with a smile on his face, looking like he had no regrets, and in addition to the pure jun with the sword handle left, there was also a booklet in his hand.

Li Xingyuan took out the booklet and took a look, but it was a book - "Sacrifice Sword"!

Although the two of them do not have the name of master and apprentice, they also have the reality of master and apprentice.

Li Xingyuan put down the booklet and saluted the old man in sackcloth sincerely, and he didn't plan to cut open the old man's body, take out his man-made meridians again, and take them to the lottery.

Now, we have to think about how to get out of this sword immortal's sleeping place.

Li Xingyuan looked around left and right, but could only see the boundless darkness, he tried to take two steps outside, and it didn't take long to find that it was already cold and bottomless water, he held his breath and stared, and then a fierce man plunged into the dark water.

He's diving.

In the absence of an oxygen tank and any cyber modifications, the limit of human breath-holding is approximately twenty-two minutes.

This is also without any movement.

Anyone who has ever swam knows that swimming is far more difficult than moving on land, and to put it bluntly, the human body structure is designed for land movement after all, and swimming is just a brave attempt made by humans as land animals for amphibians.

But the monks are different.

After Li Xingyuan entered the water, he immediately choked on a large mouthful of water, and the water poured ferociously into his stomach and trachea, making him struggle violently because of the pain in his lungs, but when he continued to go down in the process of struggling, when his lungs were all filled with water, Li Xingyuan choked out a mouthful of blood, and then opened his golden eyes.

He began to be able to breathe freely in the water.

As a backup respiratory system, the artificial meridians are put into operation.

It is efficient, cold, and extremely fast to restore the operation of Li Xingyuan's body functions, the aura replaces oxygen and begins to supply energy to the entire body, and it is obviously much stronger than oxygen, although the aura is a thin thing in today's atmospheric environment, it is still enough to ensure the operation of Li Xingyuan's body.

This is the reason why monks who have just completed the foundation building operation are called the 'Bigu Period'.

Theoretically speaking, as long as the body is implanted with artificial meridians, and the body participates in the aura circulation between heaven and earth, then all external objects are no longer needed by the body, as long as there is aura, then the monks can not eat, drink, sleep or even breathe, and become the so-called 'people of qi eating' in the Sutra of Mountains and Seas, and the so-called 'qi eaters live as gods' is this reason.

And the deeper you go to the depths of cultivation, the greater the gap with human beings, until in the end, you become an 'immortal'.

In the dark water, Li Xingyuan began to move in the direction of the water gushing out—he had noticed before that the water in the entire Sword Immortal's sleeping place was not stagnant water, but living water.

Since it is living water, then there must be a passage with the outside world.

Li Xingyuan sank in it, like a big black fish, floating in the dark, if he didn't implant artificial meridians, not to mention suffocation, even hypothermia would have killed him, but now he was completely unaffected, and it didn't take long to discover where the flowing water came from.

The designer of the place where the sword immortal sleeps doesn't know who it is, but he skillfully controls the speed and flow of the seawater pouring in outside, and filters out the impurities, Li Xingyuan saw a set of exquisite equipment composed of a water filter and a flow controller, he stood at the outlet of the flowing water, and found that the flow here was smaller than he expected, and there should be several such machines in the entire ovoid building.

Li Xingyuan calmed down, changed the angle of his body shape in the water, stepped on the device, and then raised his Optimus Hand, which lit up with a burst of blue light, and then slammed it down.

The equipment buzzed, and was smashed and distorted by the complete destructive power of the Optimus Hand, and the entire equipment let out a wail, Li Xingyuan slowly waited for the aura to recover, and then with another punch, the entire equipment was completely destroyed, and Li Xingyuan was instantly washed out of several meters by the influx of seawater, and he turned over several times before stopping.

The balance between the internal and external pressure between this place and the outside world has been destroyed, and a large amount of seawater has poured in from the equipment that Li Xingyuan destroyed, Li Xingyuan floated in the water, slowly waiting for the seawater to fill the entire ovoid building, and the artificial meridians in his body also stirred the aura, making his body further adapt to the sudden change in water pressure.

Li Xingyuan wanted to wait until the water pressure was completely calm before leaving the oval building, but under the water, he suddenly heard a loud muffled sound, and the whole building began to tilt downwards - it couldn't sink with the ovoid building! Otherwise, Li Xingyuan will really sink to the bottomless abyss! Even a monk with man-made meridians would never be able to survive under that kind of water pressure!

Li Xingyuan kicked the water and walked towards the water hole, a large amount of water was still pouring in, the power of the water was so huge, it almost squeezed Li Xingyuan's whole person, but Li Xingyuan gritted his teeth, and could almost hear the sound of his bones breaking under the pressure of the water, and finally left the building with the flowing water before the oval building completely collapsed.

At the moment when Li Xingyuan left, he heard a muffled sound again, he didn't have time to look back, for fear that he would be swept up by the water pressure of the sinking ovoid building and sink into the abyss, and the whole person desperately swam outward, and when he finally swam to a safe place and looked back, he saw that the place where the sword immortal was sleeping was like a huge, black egg, slowly sinking to the bottom of the sea.

Before Li Xingyuan could breathe a sigh of relief, he saw that there was something swimming in the bottom of the sea, it was huge, full of fluorescent, snake-like things, disturbed, and was going up from the bottom of the sea.

Is that...... Dragons?
