Chen Fei's face showed a look of surprise, because he suddenly found that there was a very small thing in the spatial ring, which he had not paid attention to before, and had been ignored in the past.

As soon as his mind moved, this very small thing appeared in the palm of his hand.

It's a kind of millet that seems to be a seed that exudes a special aura.

"System, what is this thing? Is it the seed of the elixir of heaven and earth? ”

Chen Fei's face showed joy.

"It should be a fourth-level heaven and earth elixir seed." The system said, "In the universe, on those green planets, if you can find the elixir of heaven and earth, it is basically the first-level heaven and earth elixir, and the second-level is the rare water chestnut." Only through guò special cultivation, or genetic repair, can the quality of the heaven and earth elixir be improved. Unexpectedly, this turned out to be a seed of a fourth-level heaven and earth elixir. Perhaps, Chu Mengyao used this space ring to contain the precious heaven and earth elixir and dropped a seed, but she didn't notice it. Otherwise, she wouldn't have given you such a precious heaven and earth elixir. ”

"She has taken my three heaven and earth elixirs, and she is not willing to send me a heaven and earth elixir?"

Chen Fei was stunned.

"It's not easy to cultivate a high-grade heaven and earth elixir." The system says, "And every heaven and earth elixir has a special function. Therefore, any kind of heaven and earth elixir is very precious to those powerful martial artists, and they are not willing to give it to others. That invisibly may make the enemy stronger...... For a strong person like Chu Mengyao, she can cross the universe and search for heaven and earth elixirs in the universe. Therefore, when she went to any planet, she regarded the elixir of heaven and earth on that planet as her own. Because she has the strength to get. She got three heaven and earth elixirs on the earth, and then gave you a space ring, mainly to see Li Qingzhao's face. Otherwise, the space ring will not be given to you either. At that time, when the Yu Clan was transitioning to the cultivation civilization, the four evil gods had occupied countless heaven and earth elixirs...... Ordinary people can't get it. ”

Chen Fei was still a little incredulous, but he remembered the indifferent aura emanating from Chu Mengyao's body, which was a kind of contempt, a kind of confidence, and a kind of pride.

Then he realized that what the system said was true.

Even, he can speculate on a lot of things.

When Chu Mengyao came to the earth, he immediately discovered the two spiritual elixirs of heaven and earth that emitted spiritual energy that countless Wang Lian and Chen Fei had planted in the greenhouse.

So, she didn't hesitate to take it.

There is no guilt in the slightest.

As for the three mushroom-type heaven and earth elixirs, since Chen Fei did not cultivate and cultivate them on a large scale, and did not exude any heaven and earth aura, and there was nothing too strange, she did not find it.

Then she used her great magical powers to find a genius for cultivation on the earth, and found that Li Qingzhao could inherit her mantle, she was overjoyed, and she wanted to accept Li Qingzhao as an apprentice.

Li Qingzhao is not an ordinary girl, she has a firm heart and will not be confused by the strength and magic of the other party.

Therefore, Chu Mengyao had to say the crisis of the earth before Li Qingzhao gave in and was willing to be her apprentice, but the premise was to let Chu Mengyao protect the earth for a while.

Chu Mengyao arranged a large array to block the leakage of heaven and earth's spiritual energy.

Li Qingzhao came to say goodbye to Chen Fei, and Chu Mengyao had a kind attack and gave Chen Fei a space ring.

But she didn't notice the seed of some kind of heaven and earth elixir that fell from the space ring.

"I'm lucky." Chen Fei was secretly happy in his heart, and his eyes were burning as he looked at the seed of this heaven and earth elixir, "I don't know what this heaven and earth elixir does?" system, you repair the genetic defects of this seed. ”

As soon as his words fell, the repair began.

About an hour passed, and the voice of the system sounded in Chen Fei's mind, "The repair has been completed, and the genetic defects have been repaired six times, so that the genetic perfection of this heaven and earth elixir has been increased to 47%, it should belong to the sixth-level heaven and earth elixir." ”

"Sixth-level heaven and earth elixir?"

Chen Fei's face showed a look of ecstasy, and then he asked suspiciously, "How come it is that only ten genetic defects can be repaired?" ”

"This heaven and earth elixir has been specially cultivated, and the genetic perfection is already very high, and it is very close to the limit, so it can only be repaired ten times. It's the limit. The system explained.

"The cultivation civilization is really powerful, and it can even improve the quality of the heaven and earth elixir."

Chen Fei was secretly shocked in his heart, "If that's the case, then can they also improve people's cultivation qualifications?" ”

"Improve people's cultivation qualifications? I guess they can't. Otherwise, there would be no need for Chu Mengyao to search for a successor to the mantle all over the universe. The system analysis says.

Chen Fei nodded, still puzzled and surprised in his heart, what method did they use to improve the quality of the heaven and earth elixir?

You may have to go to the Aquarius system to find out.

He walked into the villa and planted the seed of this elixir of heaven and earth in the soil of a flower pot. Then he stared with anticipation written on his face.

But to his surprise, this seed did not grow at all.

Nothing has changed.

"What's going on? The system has repaired the genetic defects, and it should have the ability to grow rapidly. ”

Chen Fei's face showed too many doubts.

"Perhaps, the growth conditions of this heaven and earth elixir are very special." The system said, "The Yu clan has also obtained many kinds of heaven and earth elixirs, and some of them are not planted in the soil, maybe they are planted in water, or they may be planted on special minerals, or they may have special requirements for the composition of the air. ”

"Could it be that this is the elixir of heaven and earth planted in water?"

Chen Fei was in good spirits, and immediately grabbed the seed of this heaven and earth elixir, drove back to Feige Pharmaceutical, and entered the greenhouse. Throw this pill of heaven and earth elixir into the water of a pond.

However, nothing has changed from this seed.

Soon Chen Fei did more experiments, but the seeds still could not germinate.

He had to put the seeds away, and a special thought also surged in his heart, maybe Chu Mengyao knew that the space ring had such a seed of heaven and earth elixir, but she knew that there was no way to cultivate it on the earth, so she ignored it.

He sat cross-legged and began to cultivate, while he detached a part of his consciousness and pondered it.

It is not too difficult for me to improve the technology of the earth and create super powerful technological weapons and mechas, because I have a system left to me by my father, which systematically records the technological civilization of the Yu Clan. However, it is very difficult to improve the strength of the earthlings, after all, they only have a hundred years.

Gradually, however, his face showed a calm look.

It seems that he has found a good way to quickly improve the combat power of the earthlings.
