After the group walked into the stone gate, the stone gate closed again. And all means of communication seem to be blocked, that is, if you want to get out, you can only go forward, and there should be another exit ahead.

People walked along the passage, and the dark and deep passage did not know how far, first downward, then level, and half a day later came to an underground world. It is said to be an underground world, but the top is covered with fluorescent stones, which illuminates the entire underground space not so dark.

Xia Yu followed the divination and followed the flow of people, looking around at this space, which was very similar to the architecture of Middle-earth at that time, but it was very different from Middle-earth, and it should be another branch of the ancient clan.

As the aura became more and more intense, everyone had come to the depths of the underground space. A stone bridge crosses the front, and in front of the stone bridge is a stone tablet with a description of the underground space in the ancient language. Xia Yu knew the language of the ancient race, but the mechanical race and the cosmic humans were also familiar with the language of the ancient race.

Everyone looked up at the stone tablet in front of them, and it turned out that this was a place of trial within the ancient clan, called the Eighteen Bridges. The eighteen bridges of the ancient clan, those who pass can obtain the ancient clan body refining exercises and physical skills inheritance.

The first to reach the bridge were the mechs, who didn't seem to feel anything, and just crossed the first bridge and walked forward. Looking at the human vassals again, as soon as they stepped on the bridge, their faces immediately turned red, as if they were carrying a mountain, and they were taking difficult steps one by one. After walking a few steps, he stopped.

As the human race walked on the bridge, Xia Yu also followed the first bridge. Just as Xia Yu stepped on the first bridge, he felt as if he was spying on him again, and then the aura around him squeezed his body like a spirit, making it difficult for him to move. Xia Yu hurriedly picked up the Heaven Swallowing Overlord Body Technique, and after feeling better, he continued to take a few steps forward.

Several human feudal powerhouses walked very slowly, but at least they could move forward, but the mechanical clan walked over as if nothing happened. Xia Yu, who was a little puzzled, took the initiative to ask.

"Lord Divination, why don't those cybtrons have any pressure at all?"

"Their mechanical clan is artificial intelligence, although they can simulate the human body and use spiritual skills or physical skills, but after all, they are not life, and this place is not suitable for them." Diviner said.

"Just like the second universe, even if everything can be simulated, all creation is based on reality, intelligent in itself but not life after all." Xia Yu said secretly.

Divination Hou looked at Xia Yu with a relaxed face and continued.

"This so-called Eighteen Bridges should not be based on physical strength, but to test the progress of the trialist. That is, from the first time you stepped on the stone bridge, the Gu Clan already knew what strength your body was in, as long as you can improve your body in the process of moving forward, then you can continue to move forward. ”

Xia Yu used the Heaven Swallowing Overlord Body Technique while following the divination and walked forward. But after a while, the divination stopped.

"Xia Yu, I can't do it, you continue, even if those mechanical clans reach the end, but because they are not life, there should be no gain, you have a good foundation, there is more room for improvement, you go ahead and try!"

Xia Yu left the divination waiting, and walked forward alone, catching up with the human people in a few steps, but those human feudal lords seemed to be in trouble on the first bridge. One of them's body exploded directly, and then he took out a righteous corpse, and after the soul entered, he was able to make great strides soon.

"It seems that the ascension of the righteous remains is also recognized, as long as the physical strength of the person who confirms the soul increases, he can move forward, and the righteous remains are also counted!" Someone said.

As a result, many of the feudal lords who used the righteous remains were replaced with stronger righteous remains. Quickly crossed the first bridge. Xia Yu also walked across the first bridge with everyone.

Then came the second bridge, the pressure increased again, Xia Yu simply sat down directly, and after practicing for a long time using the Heaven Swallowing Overlord Body Technique, he felt that the pressure was less, and then continued to move forward.

The aura of this second bridge is even richer, Xia Yu's cultivation here is twice the result with half the effort, and with the soul of his own origin spirit, all the aura is even closer to Xia Yu.

Xia Yu was meditating and cultivating on the third stone bridge, and the aura around him penetrated into Xia Yu's body like life, and Xia Yu grinned in pain. This Heaven Swallowing Overlord Body Technique is good for anything, but the cultivation process is too hard, especially under this hundreds of times the rich aura, the pain is also doubled and intensified.

By the time Xia Yu walked to the Fourth Bridge, some of the human feudal lords had already stopped, sat in place, and were cultivating with the help of spiritual energy, obviously there was no better righteous corpse to support them to continue to move forward. Xia Yu found a place to continue meditating and cultivating.

Halfway through, the cybborgs had already turned back. Looking at the strong people of the human race, analyzing the current situation. The cyborg people also discovered that they couldn't get this so-called ancient clan inheritance. Even if the mechanical family reaches the end point, it will not be able to open the box. So an ultimatum was given to the human race.

"We'll wait for you at the end of the stone bridge, and if you have the ability to come up and open the box within a year, we cybbs will share it with you. If not, we will destroy this place of trial. Come on! After saying that, these powerhouses of the mechanical clan left directly.

Humans look at each other's embarrassment, and they also know the meaning of the mechanical race's approach, since we mechanical people can't get it, then we humans can't let it get it. Within the specified time, human beings can complete the inheritance, and everyone can still talk about it. If it can't be done, the mechanical family will directly flip the table, and no one will be able to take advantage of it.

The existing feudal level powerhouses, those who rely on the righteous remains can no longer advance an inch when they reach a certain level. The rest of the feudal lords who did not have righteous remains were advancing while cultivating, as slow as a snail, but it was only Xia Yu, a B-level life, which impressed everyone.

"Xia Yu boy, you leave us alone, rush forward directly, if those mechanical clans have bad intentions for you, you run back directly, we will cover you!"

"Boy, you shot our Caesar Army, if you want to live, go and get that inheritance back, and then!" That Taurus Hou actually threw Xia Yu directly a C-level battle knife. Although it's just a regular quality, it's a lot of money, at least hundreds of thousands of amethyst.

"Xia Yu, if you can go up and get the inheritance, those mechanical clans will definitely not let you go, you find a way to delay time, as long as you can come down, we will protect you safely." After Feng Tianhou finished speaking, he threw another piece of C-level armor and gave it to Xia Yu.

"Okay, I'll do my best, you guys just practice hard here, a year's time, it's not bad to practice well, goodbye!" Xia Yu put away the gifts of these people and walked forward here.

A month later, Xia Yu had already walked to the sixth bridge, meditated and practiced on the bridge with his knees crossed, and half a month later, he walked across the sixth bridge. But when it came to the seventh bridge, it took twenty days of cultivation to cross the bridge.

Three months later, Xia Yu had already arrived at the Tenth Bridge, and the pressure here made Xia Yu feel like his flesh and blood were about to be separated. During the cultivation, the gums were bitten out of blood. If it weren't for the soul strength enough, he might have fainted in pain.

Half a year has passed, Xia Yu has reached the twelfth bridge, according to the progress, Xia Yu feels that it is really impossible to spend the eighteen bridges in the remaining half a year, the more he goes to the back, the greater the pressure of the aura, and the time he needs to refine and absorb is getting longer and longer.

Seven months later, Xia Yu arrived at the thirteenth bridge, at this time Xia Yu could no longer move forward, not because the pressure was too great, but his body had reached the limit, if he continued to move forward now, he must break through to the third stage of the Heaven Swallowing Overlord Body Technique, and cry blood into a river. Once he broke through, Xia Yu's body would be the first to reach the level of C-level life.

Xia Yu's whole body cells were saturated again at this time, and the cells that had just changed their genes in order to survive were facing the challenge of life and death again after just over a hundred years. Some of the cells have been directly burst by the aura. But the aura was still infused as usual. Xia Yu's face changed red, and the corners of his mouth had begun to contain blood. But it's still insisting, if you can't persevere, then the body will become resistant, and it will be even more difficult to break through next time.

The bastard also stood by Xia Yu's side at this time, watching Xia Yu's performance, worrying about him vigorously. A day later, Xia Yu's seven orifices began to bleed. The soul also ached. Two days later, blood beads seeped out of Xia Yu's skin, and Xia Yu could no longer speak at this time.

Three days later, Xia Yu was dripping with blood, and before the blood on the surface of his body dried up, new blood seeped out of his body. The pain can no longer indicate Xia Yu's current state, a heart of death was born in Xia Yu's brain, yes, it was too painful, Xia Yu thought of death, but as soon as this thought was born, it was forcibly pressed back by Xia Yu, although he was covered in blood, but Xia Yu leaked a smile.

Xia Yu, who was smiling, continued to devour the aura around him, Xia Yu felt that his blood was about to run dry, but the devouring continued. Just when Xia Yu felt that his consciousness was beginning to be chaotic, he felt that his body was slowly changing, yes, those stubborn genes had begun to succumb.

Even though only a small fraction of the body's cells have chosen to succumb to the genes, they are changing their order so that they can accommodate more of the aura. But this is a good start for Xia Yu, more and more cells choose to change, and in order to survive, they are forced to change their genes. Xia Yu's entire body has also undergone drastic changes.

A week later, on the thirteenth bridge, a humanoid creature wrapped in black-red slime was like the center of a tornado, and the already rich aura around it was attracted by something, and it frantically burrowed into the humanoid body. After a long time, the aura regained its calm, and the pair of black eyes on the flesh also shone brightly.

"It's finally time for the third stage, so the road ahead will be much easier!" Xia Yu, who opened his eyes, said to the bastard.

"Great, you've finally survived, I'm afraid you won't be able to hold on or someone from the middle of the cyborg will come!" Bastard said worriedly.

"Huh, automaton? Now that my physical body has reached the level of C-level life, even if the soul strength is still B-level, it is not so easy for those cybbers to deal with me! Xia Yu said with a smile.

Then, Xia Yu took out the water from the storage bracelet, cleaned himself, and looked at the golden body, Xia Yu felt stronger than he had ever been. Putting on the C-level armor sent by Feng Tianhou, Xia Yu continued to walk forward.

The fourteenth bridge, Xia Yu felt like a spring breeze, the fifteenth bridge, Xia Yu did not have any difficulty, and the sixteenth bridge, Xia Yu felt the pressure, but he also persevered. On the seventeenth bridge, Xia Yu walked a lot harder, and after half a month of cultivation in the middle, he finally reached the eighteenth bridge.

On the eighteenth bridge, when Xia Yu was halfway there, he had already seen the cyborg people on the other side of the bridge and behind those people there were three stone boxes, and these cyborgs were meditating on the stone boxes. Xia Yu ignored it, and just meditated in the middle of the eighteen bridges.

"In four months, I'm going to raise my physical body to the highest state, and when the time comes, I'll have the ability to protect myself when I face the cybani." Xia Yu sighed in his heart.

So Xia Yu took advantage of the rich aura of the eighteenth bridge to cultivate. The slightest aura is like a dragon, and it continues to nourish Xia Yu's C-level body.
