In this cave, there is the light of the night pearl, and Wang Heng'er has also found out the method to dissolve the toxicity of the Yuan Energy Fruit and refine it into the energy he needs, so that his life can be maintained for a while. After he ate the two Yuan Neng Fruits, he felt that the Yuan Force of Xiu Nei was often agitated, which showed that his Yuan Power had increased a lot, and in order to dissipate some of the Yuan Power in his body, he often practiced the Taiyu Sword Technique, so that the essence of the Taiyu Sword Technique was further understood.

It's a little weird, since he wanted to catch a few bats for dinner, and followed their flying shadows to practice the last move of Taiyu Swordsmanship, the bats have never appeared, maybe they found out about Heng'er's behavior, are they afraid that Heng'er can really catch them as food?

The usual loneliness was restored to this cave.

Heng'er knows his situation very well, this kind of life, after all, cannot be long-term, and finding the exit of the black hole is the only way out.

He looked up at the top of the hole, and there was no light on it, and he really didn't know how deep the hole was!

He searched for his memories of the time he fell, and he learned that when he fell, it was not a straight line, but a few turns before falling to the hole.

He had eaten the Yuan Neng Fruit, and his physical strength had doubled, and he was ready to climb up again, hoping to find an exit. As long as he sees the slightest light from the outside world, he can find the exit.

So, he once again used light skills and now climbed upwards. As the higher the climb, the brighter the night pearl became, and finally the light of the night pearl disappeared under the cave. The top of the cave entered the endless darkness again, the more he climbed, the greater the depth of the darkness, and finally he couldn't even see the most basic cave wall, he struggled to climb in the darkness for a while, still couldn't see a little hope of light, at this time his physical energy was greatly consumed, if he climbed up again, it was likely to lose strength for a while, causing the danger of falling downward, he had nothing to do, so he had to return to the same place.

He came to the platform and looked at the glowing night pearl in a daze. However, after this climb, he deeply realized that it was almost impossible to climb up to find the hole of the hole.

At this time, Wang Heng'er was exhausted and didn't know what to do.

But he thought again: "Since someone comes in and can carve words on the wall of the cave, and leave a secret book of martial arts in this cave - Taiyu Swordsmanship, it means that this place must not be far from the outside world." ”

"There must be a passage to the outside world, but so far, I haven't found it. ”

"I don't believe that I can't find an exit, and when I return to the light of day, I'll be trapped here!"

Wang Heng'er rested for half a pillar of incense, he mustered up confidence, and practiced the Taiyu swordsmanship, while practicing, he suddenly had a whimsy, if he could raise his inner yin gong to another level, to reach the second level of the dantian of the inner yin gong, and then use the Taiyu swordsmanship to gather the yuan force on the small copper sword, with his own strength, use the small copper sword to continue to dig into the rocks in the cave cliff, maybe he can open up a way out to the outside world.

He stopped practicing the sword, and thought that the toxicity of this Yuan Energy Fruit could be discharged from his body by practicing the Taiyu Sword Technique, and his energy could be turned into already there, although it had not been ten days, could he eat another Yuan Energy Fruit to replenish his own energy, increase his own Yuan Force, and launch an impact on the Dantian Duo of the Inner Yin Gong?

"Anyway, it's better to try, than to be here and just wait for death. ”

For this reason, in order to improve his inner yin skills and open up an exit to the outside world, he jumped into the Yuan Neng Grass again, picked two Yuan Neng Fruits at once, and returned to the stage.

He didn't have any appetite at all, but because of that kind of eagerness, he still ate the two red yuan energy fruits one by one, and quickly ate the two red yuan energy fruits.

After swallowing the two Yuan Energy Fruits raw, they quickly flipped the Taiyu Sword Technique, expelling its poison and refining its energy quickly.

This time, he played a full set of Taiyu sword techniques, as before, unconsciously he was surrounded by a cloud of purple-red mist, first very thin, then heavier and heavier, this time the purple-red mist was thicker than before.

After a long time, the purple-red mist gradually thinned out, and finally disappeared completely.

At this time, Wang Heng'er felt that the lower dantian was burning like fire, and there was a powerful yuan force in the lower dantian impacting his whole body, and his body seemed to explode immediately, making him miserable and wanting to cry without tears.

"At the beginning of the detoxification, you used that ray to expel the poison, and now you have practiced a full set of Taiyu sword techniques, and all the toxins have been turned into mist and discharged, boy, why did you eat two Yuan Energy Fruits at once? There is too much energy in your body, and there is a danger of energy explosion. ”

This is the text that Gu Xia showed in his head, Heng'er only then remembered that before doing all this, he should ask Gu Xia if it was feasible, he really regretted this behavior, but the matter has come to this, then the only way to ask him is the solution.

"What then?" asked Heng'er eagerly.

"You quickly raise the Inner Yin Gong Dantian to a heavy, use your own Yuan Force to confront the Yuan Force generated by the two Yuan Energy Fruits, and force the Yuan Force generated by the Yuan Energy Fruit to rush outward back to the lower dantian and suppress the explosion of its energy. This text came to mind.

He got Gu Xia's reply, and he followed the prompt, sat cross-legged, quickly raised the Inner Yin Gong to the first level of the dantian, and used his own Yuan Force in the opposite direction to the Yuan Force generated by the Yuan Energy Fruit, and rushed out of the body against the Yuan Force generated by the fruitless Yuan Force.

With the help of Gu Xia, after several battles, the Yuan Energy Fruit generated the Yuan Power Fruit finally returned to the Lower Dantian, and the pain in his body as if it was about to explode was slowly relieved.

As the body expanded, the feeling gradually disappeared, but I felt that the burning sensation of the lower dantian was worse than before. Heng'er wanted to see what was going on in his lower dantian, so he activated the inner vision method and probed into his lower dantian.

I saw a sea of fire in the lower dantian, which was formed by the energy that forced back the yuan force, and the lower dantian showed the yuan baby, holding a fiery Zhu Dan formed by the yuan energy fruit in one hand, and threw it into the fire, the fire gradually weakened, and the Zhu Dan inhaled the fire and became more and more red. The Yuan Infant picked up the red Zhu Dan, merged them together, and after kneading them with both hands, he swallowed them together, and the Yuan Infant immediately shone brightly, and gradually changed from the Yuan Infant to a rabbit.

"Boy, you have been blessed by misfortune, you have been promoted from the first dantian to the second dantian. Heng'er's mind appeared with the words of Gu Xia.

Wang Heng'er was overjoyed when he saw this strange image and the words that Gu Xia appeared, his inner yin skill had really risen to the next level, and the dantian was double, it was really as he wished.

He stopped looking inward, opened his eyes, and under the illumination of the night pearl, the projection of a rabbit in the lower dantian on his body was clearly visible on the cave wall.
