This underground world couldn't see the sky, but he didn't know where the faint light was coming from, so Zhuo Yu could barely see what was around him! They unconsciously left the wet soil covered with blood, which made him feel much better.

Zhuo Yu didn't know where to go with Li Feng, and Li Feng didn't say anything, in short, now Zhuo Yu has treated Li Feng as an elder.

"Brother Li, do those people of the evil clan fight each other as soon as they meet?" Zhuo Yu asked, if this was the case, it was hard for him to imagine how this group of guys had lasted for so many years.

"It used to be, it wasn't now! Now they have a system to fight, they are divided into several factions and gathered together, and every now and then there will be a big battle, and those who die will be used as food!"

A kind of nausea suddenly surged into Zhuo Yu's heart, and he muttered: "This is war! Let the stronger survive and let the weak die, it seems that this must have been taught by the Demon Dragon Guard!"

"Demon Dragon Guard?" said Li Feng.

Zhuo Yu briefly talked about this matter, and let Li Feng know that the Demon Dragon Guard was not a good thing.

"Brother Zhuo, what are you looking for, where to put it?" Li Feng asked again.

Zhuo Yu shook his head and said, "I don't know, I just know that the thing is placed here, about what it is, I promised a person, I can't talk to others." Please also forgive Brother Li. ”

"It's okay!, but the strength of those guys of the evil clan is not weak, it is difficult for me and you to compete with them, now we should first blend into their territory, find a place to settle down, and then slowly inquire about the location of that thing, and at the same time improve your strength!" Li Feng smiled, he could understand Zhuo Yu.

"Brother Li, don't you go back to where you came from, then what have you been eating?" Zhuo Yu asked, because the kind of soil that Li Feng ate only had in one place.

At this time, Li Feng took out a small bag from his bosom and poured out a few mud pills, which were black, as if they were made of a kind of black soil.

"It takes a month to digest one pill completely, and I still have hundreds of pills here, enough to eat for a long time!" Li Feng laughed.

The corners of Zhuo Yu's eyes twitched slightly, originally he thought that eating mud was like eating and stuffing it into his mouth, but it turned out that he was just eating mud pills, and what surprised him the most was that a person like Li Feng who had a strong body could last for a month by just eating one pill!

This mud pill was like a panacea in his eyes at this time.

"Brother Li, can you give me a pill to taste?" Zhuo Yu also felt a little funny when he said this, and actually asked someone else to ask for mud pills to taste!

"Of course you can, this kind of thing is everywhere in that place!" Li Feng laughed, grabbed a handful and handed it to Zhuo Yu.

After Zhuo Yu took it, he took out a storage ring and handed it to Li Feng, and said, "Brother Li, this is my little heart for you, you drip blood on it, and then your spiritual power will seep into it......"

Zhuo Yu has a lot of storage rings, and it is nothing to give a strong wind, and Li Feng listened carefully how to use this magical thing, and he was also very excited after arriving at this storage ring.

"It's amazing, it's so convenient, it's so ......big inside," Li Feng said with a big mouth, because he hadn't heard of the storage magic weapon at all, his things were all carried with him, and if there were some big things, he had to find a place to hide them.

Zhuo Yu smiled, picked up a black mud pill the size of a little finger, sniffed it, and then asked the tree spirit with his spiritual power: "Sister tree spirit, what is in this mud pill?"

"This dirt...... If I'm not mistaken, this soil has been soaked for a long time in something called life force, so it contains a wealth of life force! How did such an abundant life force come into being in this underground world? Could it be that people like Li Feng were infected by this life force to get rid of that evil consciousness?"

Life force, Zhuo Yu never figured out what this thing was! he stuffed the black mud pill into his mouth......

The taste of the mud pill was not good at all, he frowned and swallowed the mud pill, to his surprise, an indescribable feeling of comfort suddenly spread throughout his body, making him suddenly refreshed, that wonderful and refreshing feeling kept flowing, until the fatigue of his body was eliminated, until he felt full of strength, this feeling was not so strong!

Is this the power of the life force?

Seeing the surprised expression on Zhuo Yu's face, Li Feng smiled and said, "It's not bad! I can eat one pill so that I don't have to go hungry for a month." ”

Zhuo Yu nodded, this kind of thing was much better than the recovered pills he refined!

"The greatest benefit of life force is to make life itself active, replenish all kinds of deficiencies in the life body, and let life survive better! I used a lot of life force to repair the serious damage in all parts of Tsukihime's body, including the wound of the soul! If you get the nourishment of life force for a long time, and then tap the potential of life itself through some ways, then sooner or later you will reach a peak!" said the tree spirit with emotion.

Zhuo Yu looked at Li Feng with a smile on his face, and only felt that behind his smile, he must have endured many unbearable pains that ordinary people could not bear, so that he now has great strength! If you pay, you will be rewarded, Zhuo Yu is more and more determined to follow the idea of this Li Feng cultivation, and he wants to quote the path taken by Li Feng and open up his own path.

Just as Li Feng said, that mud pill couldn't be digested for a while, and Zhuo Yu could feel that the mud pill was exuding a trace of weak life force.

Zhuo Yu followed behind Li Feng, and after running fast for ten years, he saw a huge mountain appear in front of him! Although this mountain is not high, it is very large, and there are many large and small holes on this mountain, and Zhuo Yu can see some people coming in and out from those holes.

"The inside of this mountain is empty, and there are those evil people living in it!" said Storm.

"So, this is considered a force?" Zhuo Yu asked, built in the belly of a mountain, if the battle is fierce, the entire mountain will be destroyed, and it will be impossible to escape.

"This should be a heart eater, only eating hearts and internal organs, and the overall strength is quite good!" Li Feng nodded and said.

"Do they have to eat every day? If they only eat offal and eat it every day, how can so many people give them food?"

"The number of those demons is very large, and they multiply and grow quickly, so there are quite a few people who can get food! The mountain you see now can only be entered by some people with strength, and those who don't have strength are wandering outside, either being eaten or eating others!"

Hearing this cruel way of survival, Zhuo Yu could only sigh: "How were they all born? Being able to reproduce in large numbers in such a cruel living environment shows that the breeding method of the evil race must be unusual." ”

"You still don't have to know this breeding method, you know that they will breed quickly!" Li Feng's face suddenly showed a disgusting expression, he knew that Zhuo Yu felt very disgusted about eating human flesh, and in his opinion, that kind of breeding method was even more disgusting.

Although Zhuo Yu was curious, but now he quickly closed his mouth and didn't ask any more, knowing too many things was also a pain.

Li Feng and Zhuo Yu had already come to a huge hole, and at the entrance of the cave there were four big men with naked upper bodies, their faces were handsome and ugly, the muscles on their bodies were abrupt, and they carried a huge knife behind them, and it could be seen that they had a certain strength.

When the four of them saw two neatly dressed people coming, their brows immediately furrowed, and they saw Li Feng take out two small bags and hand them over, these are two hearts!

This is the entrance fee, the four big men nodded with great satisfaction, and let Zhuo Yu and Li Feng in.

After entering inside, Zhuo Yu breathed a sigh of relief, he knew that Li Feng brought him in to familiarize him with the things here, and by the way, he inquired about that thing.

"Brother Li, it turns out that you have already collected those hearts!" After Zhuo Yu killed those bloodthirsty ants, he did not take their corpses, and now he feels a little pity, because that heart is equivalent to "money", as long as there is money, it is easy to do things anywhere!

"I've only taken a few, if I'm worried about not having them, I can kill a few here, there are a lot of people here, who knows, no one will track them down!" Li Feng laughed in a low voice.

Entering the belly of the mountain was a large pitch-black passage, with a faint white light in the distance, when he and Li Feng passed through this passage, Zhuo Yu was stunned, he suddenly felt that it was like an ant nest in it, and there were large and small holes everywhere.

He and the wind entered the belly of the mountain, and there was a faint light in it, which was illuminated by fluorescent stones, and it was very empty, and the walls of the huge mountain belly had been dug out of many caves, and those people and evil tribes lived in it.

What made Zhuo Yu feel unbelievable was that these evil clans actually knew how to strike iron to make weapons, and there were still many ores under this deep ground, and Zhuo Yu didn't need to think about it to know that it must be those demon dragon guards who taught them forging skills.

On the ground of the mountainside there are stalls of all sizes, most of which sell weapons and bloody bones and corpses......

Zhuo Yu suddenly wanted to vomit, he took a few deep breaths, and didn't let himself vomit, if he hadn't seen it with his own eyes, he couldn't imagine that there would be a place where human flesh was put out for sale like pork, and there were many body parts.

Seeing Zhuo Yu's face, Li Feng hurriedly took Zhuo Yu away, away from this place full of stench, Zhuo Yu looked at these evil people, they actually set up stalls in a very orderly manner, and walked around the streets, these heart eaters look no different from humans, the only difference is that they are dressed very simply, but there are some things made of unknown materials on their bodies, and there are no women in this heart eater!

How can you have a child without a woman?Zhuo Yu was curious about the reproduction of this Heart-Eater, but he was afraid that if he found out, he would destroy his stomach.

"This is hell!" Zhuo Yu snorted and honestly followed behind Li Feng.
