In the west, deep in the cracks of the sinkhole......

Yu Tiancan felt as if he had entered another world.

When he first arrived, Yu Tiancan was deeply shocked by the environment here.

There have been famous foreign directors who have filmed the movie "The Underworld", but the scenes in it are completely different from what he has seen.

Deep underground, there are dry riverbeds, hideous and dangerous rocks, and caves are built in all directions, like a city hidden underground.

On the first day he came, the prison emperor directly healed Jing Huaiying's injuries.

"I'm not a doctor, but I know what makes a person healthy." The Prison Emperor's answer was very bland. Without any medicine, he healed a man who had been seriously injured with his own hands. And it seemed like a common thing to him, and it was not worth showing off.

After all, Jing Huaiying is also a master of rebirth, and with the help of the Prison Emperor, it didn't take long for her body to fully recover.

As for Yu Tiancan, he had no time to rest at all, and the strange patterns carved on the stone walls of the cave attracted all his attention.

The prison emperor brought Yu Tiancan here and let it go.

And after Jing Huaiying recovered from his injury, he went to visit the prison emperor once, I don't know what the prison emperor talked about with him, after he came out, he frowned, looking like he was meditating.

Yu Tiancan didn't know how many hours had passed, but he felt that his stomach was empty, and he found the prison emperor hungry.

"By the way, I almost forgot. You still need to eat, wait for me here. The Prison Emperor left a sentence and turned to leave.

Twenty minutes later, the Prison Emperor walked into the cave with a wild boar and a bundle of wild vegetables.

"Where did you find that?" Yu Tiancan asked in surprise.

He hadn't been to a few caves surrounded by lava or steep and difficult to navigate, and he had walked everywhere. In such a hellish place, it's nice to be able to catch a mouse, not to mention the shiny boar and fresh vegetables.

"Outside." The Prison Emperor sat down, smiled and said, "The last time I went out was in winter, and this time I went out, I found that a levo-willow had grown at the mouth of the sinkhole this time. ”

"Uh......" Yu Tiancan really didn't know what to say, they had only climbed less than half of the path in their lives. And the prison emperor walked back and forth in twenty minutes, and brought back sumptuous things, looking not red in the face and not beating in the heart, as if he had gone out to the vegetable market for a short walk.

"These things should be enough for you and Jing Huaiying to eat for a few days. Let's hope we don't stay here for too long. ”

"Aren't you going to eat?"

"For me, the food wasn't perfect. And there is also a slight poison in pork. The Prison Emperor shook his head and said, "You see that floating in the air contains all kinds of elements that the human body needs. Frankly, I haven't eaten in three or four months, and I occasionally feel hungry, but I don't need much food. ”

Yu Tiancan was speechless again, and secretly thought: "Have you been lonely for a long time and are you looking for someone to show off your skills?" ”

"You eat first, I still have something to think about." After the Prison Emperor finished speaking, he turned around and left.

"Wait, the meat is raw, how can I eat it!" Yu Tiancan hurriedly called the Prison Emperor.

The Prison Emperor paused, turned his head and glanced at the wild boar, and said, "It's ripe now." ”

"Who are you coaxing?" Yu Tiancan said in disbelief, and as soon as he finished speaking, he suddenly smelled a fragrance, and looked down to see that the whole pig weighing more than 200 catties was not only cooked, but even the skin was already burnt.

Yu Tiancan laughed, finished eating, and looked in the stone cave at the bottom of the shaft, there were many lines on it, as if the amount of information that he had not been exposed to in the past ten years was in front of him, and he was hungry for learning.

There was no sun and moon in the cave, Yu Tiancan's eyes were deep, his eyes were red, his eyes looked a little crazy, and in his deep eyes, there seemed to be a fire bursting.

"Mr. Yu, your body is too weak. The soul relies on the body, and if you don't increase your physical element, you will never be able to fully comprehend Tianyan. ”

Yu Tiancan turned his head to look, and at some point, the Prison Emperor had already walked behind him.

"You sue me, the method of heavenly performance can also enter the rebirth, but it's a pity that I haven't understood it thoroughly." Yu Tiancan sighed with emotion and said, "This must be the site of the tattoo civilization seven thousand years ago." ”

He walked over to a blue-brown wall, touched the strange and changing lines, and pondered.

"It should be 30,000 years ago, after the ancients evolved into new people, that their wisdom could create these things." The Prison Emperor calmly caressed the rock wall, his fingers hooked, and he easily left a mark on the rock, extending one pattern, with some strange law, matching the other.

"No wonder I feel that these marks are very light, it turns out that you carved them." Yu Tiancan said, his heart trembled.

The cave they were in was more than ten meters high, and there were strange stones hanging from the top of the cave, and the gourd-shaped cave was more than 2,000 square meters, but every place was carved with lines, even on the hot stone slabs under their feet.

The stone slabs in the cave were cracked into dozens of pieces, some of which were cracked and the cracks were as wide as two meters, and from time to time a stream of magma burst out of the cracks in the ground, hitting the ground and making a snorting sound, and the heat was rising.

Those places, Yu Tiancan didn't dare to approach at all.

He was already tired and sweating, and his hot mind was dizzy, but after the Prison Emperor came over, he felt like he had turned on the ultra-high-power air conditioner, and the temperature naturally dropped to a very comfortable temperature.

The Prison Emperor stood there quietly, like an ultra-high-power central air conditioner, automatically adjusting the temperature to the comfort of Yu Tiancan's body.

"It's just a rule." The Prison Emperor's voice clearly fell on Yu Tiancan's ears: "They used tattoos to find patterns and seek evolution, but as a result, simple things became more and more complicated. ”

"What do you mean?"

"The law of qiē in the world is actually very simple, it is just an empty word. But once it has a beginning, just like a tree sprouts, it will grow branches, and the more branches it extends, the more complicated it will become. The same goes for tattoos. There seemed to be a detachment in the Prison Emperor's tone: "I don't need a tattoo to be reborn, and I prove it." The stone wall lines on the mountain wall should have been useless for a long time. ”

Speaking of this, the Prison Emperor touched it casually, and the stone patterns on the rock wall were stroked by the palm of his hand, and became very smooth.

"Then why did you let me come?" Yu Tiancan asked puzzledly, "What are you asking me to come over?" ”
