Before that, Lin Feng only continuously improved himself by absorbing the energy in the crystal, but when he reached the bottleneck, he couldn't absorb the energy in the crystal.

But after hearing what the old man said, Lin Feng suddenly understood a truth.

Holding the green pill in his hand, Lin Feng was thinking about injecting the energy in his body into the green pill, and at the same time extracting the energy from the green pill.

In this way, what Lin Feng absorbed was the relatively advanced energy of the green pill. Then transmit those low-level energies in the soul to the green pill, so that the energy in the soul in Lin Feng's brain is gradually purified.

This is like doing hemodialysis, expelling bad low-level energy with impurities and absorbing high-purity energy. With the continuous absorption of energy, Lin Feng felt that the energy in his soul was gradually increasing.

And when the old man started to absorb the power of Lin Feng, he just looked at him with a smile. He didn't show any surprise because Lin Feng took out the green pill representing the fourth-level zombie.

Time passed by every second, and the energy in Lin Feng's mind became stronger and stronger. The energy in the green pill produced by the fourth-level zombies is quite mellow, tens of millions of times higher than that of ordinary white crystals. In front of the green pill energy, the energy in the white crystals that Lin Feng absorbed before can be regarded as garbage.

"boom!"

I don't know how long it took, but Lin Feng felt a shock in his head, and a monstrous energy came out from the soul, stretching all the veins in Lin Feng's body. This comfortable feeling has never been seen before.

Cultivator Level 8!

Lin Feng, who hadn't made any progress for nearly a month before, was guided by the old man's words. Lin Feng raised his cultivation to level 8 cultivator with only one green pill.

After reaching level 8, Lin Feng felt that he was definitely not at the same level as before, and there was definitely a watershed between level 8 and level 7.

If the energy fluctuation of a level 7 practitioner is like water released from a water pipe, then a level 8 practitioner is like a stream.

No wonder it was at the Beishan base before. Even Yang Tianlong couldn't catch a move. Now Lin Feng understands that level 7 practitioners and level 8 practitioners are definitely not at the same level.

Lin Feng, who was a level 7 practitioner before, had difficulty dealing with level 4 zombies, so now if he faced a level 4 zombie again. Lin Feng is confident that destroying it is as easy as killing a third-level zombie before.

After entering the end of the world for two full months, Lin Feng unexpectedly reached a level that no one else could reach in three years. A level 8 cultivator, he finally stepped onto the top of the pyramid at this moment.

"Thanks!"

Lin Feng, who came back to his senses, bowed deeply to the old man in front of him, and this thank you also came from the bottom of his heart.

If there is no this old man in front of you. Lin Feng was still struggling to figure out the bottleneck of level 7 practitioners. It was precisely because of the old man's words that made Lin Feng clear and let him know the way to break through this bottleneck.

The current Lin Feng would definitely not think that the old man in front of him was just an ordinary person. Before that, he wondered why the old man dared to live alone in this wilderness.

After the old man helped Lin Feng break through the bottleneck, he realized that the humble old man in front of him was a real strong man. If it weren't for that, you wouldn't know how to break through the bottleneck.

"Young man, you are being polite. Good people are rewarded. This should be my reward for eating your sauced beef."

Seeing Lin Feng bowing to him, the old man did not evade, but said with a smile.

It is precisely because Lin Feng is different from others that the old man helped him break through the bottleneck. As early as when Lin Feng approached this courtyard, the old man already knew that he was a level 7 practitioner.

People who passed by here in the past saw the old man living here, except for being curious. After seeing the vegetables he planted and the poultry he raised, they all became interested in the autumn wind.

For those people, the old man beat them out unceremoniously. Even for some people who have no greed, no one will chat and eat with the elderly in this dilapidated courtyard.

Seeing Lin Feng today, the old man thought that he would be like other people, as a high-level practitioner, he would look aloof.

But Lin Feng didn't, he just asked for a bowl of water to drink, and then chatted with him.

The old man knew that Lin Feng was curious about him living in the yard alone. But if there are more curious people, the old man will not care.

But what the old man didn't expect was that Lin Feng would actually take out the sauced beef while eating.

Meat is a rare food in this apocalypse, so a small piece of sauced beef is worth fifty white crystals. And he was just an ordinary old man who couldn't be more ordinary. Just giving Lin Feng a ladle of water and a plate of vegetables grown by himself, the other party was able to produce such a valuable sauced beef. The old man thought that Lin Feng's character was still good.

If it were someone else, let alone a stranger, even friends might not be able to offer such valuable things.

Fifty white crystals, that can only be produced by fifty first-level zombies. Although the old man knew that the young man in front of him was a level 7 practitioner, even this was not an excuse to casually give fifty white crystals.

It was because of Lin Feng's generosity that the old man felt that Lin Feng was a more down-to-earth person. Unlike others, who came here specifically to make him raise those chickens.

"You're being polite, old man. If it weren't for what you said just now, I don't know how long it would take me to improve."

After hearing what the old man said, Lin Feng said sincerely.

What he said was true, if the old man's words hadn't given Lin Feng an epiphany, he really didn't know when he would be able to reach the 8th level of cultivator.

Even if the energy of the sun in the underground world can be slowly absorbed by Lin Feng, he still doesn't know how long it will take until he reaches level 8 cultivator.

At this level, it will be much safer in this apocalyptic world. Compared with the level 7 practitioners in almost every base, Lin Feng will be a higher level than them.

"Cultivation, don't be in a hurry. Sometimes it's useless to be anxious. The best way to practice is to truly understand the true meaning of energy."

Looking at Lin Feng in front of him, the old man said simply.

Hearing the old man's words, Lin Feng's heart was shocked. The old man was telling him the essence of cultivation.

The purpose of practicing is to comprehend energy, but as for how to comprehend energy, the old man didn't say, and Lin Feng didn't know how to ask.

"Thank you, old man."

Feeling the huge energy fluctuations on his body, Lin Feng said to the old man again.

"When one day you reach my level, you may truly understand what energy is."

Suddenly, a terrifying energy fluctuation that Lin Feng had never seen erupted from the old man's body. This kind of energy made Lin Feng feel terrified from the bottom of his heart.

Soul Cultivator!

Suddenly thought of something, Lin Feng blurted out. (To be continued.)
