Wen Jing looked at Lin Feng in a daze.

"In fact, we don't need to deliberately improve the earth's aura environment, which consumes too much energy." Lin Feng said.

"Oh." Wen Jing nodded, she was only responsible for the research of science and technology, and she had never cared about energy things, because since she started researching, Lin Feng's energy supply has never stopped, and it is inexhaustible.

Lin Feng smiled.

Although he is not afraid of waste, there is no need to be so extravagant, and it is slow to improve his aura in doing so.

"According to the efficiency of each cosmic energy conversion device, test a suitable range and build an independent cultivation room." Lin Feng nodded, Wen Jing was not stupid and instantly understood, the same qi poured into a small balloon could make it inflate to the fullest, but it couldn't even bulge when poured into a large balloon.

The difference is significant.

Eight cosmic energy conversion devices are enough to build eight cultivation rooms, which can be set up as a single cultivation room, a double cultivation room, a ten-person cultivation room, and a hundred-person cultivation room. In this way, the efficiency is much higher than blindly improving the aura of the earth.

"Okay, I see." Be quiet and make sense.

Lin Feng smiled: "You just continue to study, and I will arrange for Huang Tian to take over the construction of the cultivation room." ”

Good steel has to be used on the blade, and talents like Wen Jing keep her busy with trivial affairs, which is too worthless. In the only one year she has been on Earth, she has already given herself three surprises, first the XX-level defense system, then the 50% simulation of the Yin Ke 25 series spaceship, and now she has cracked the cosmic energy conversion device.

One person is worth a million soldiers.

…

Sun Shengren, who is as famous as Wen Jing, does not contribute so much.

He is extremely obsessed with the power of science and technology, and is not interested in other fields of science and technology, Lin Feng understands that people like him and Wen Jing belong to the 'Frankenstein' type. If you force them to do something they don't want to do, it won't have much effect, but let them start with interest and keep studying, maybe they will give themselves a lot of surprises.

"What is the effect of the Huaxia Type I spiritual power liquid developed by Shengren?" Lin Feng asked.

"It's very good, it's 75% higher than the effect of the best spiritual power liquid in country M at that time." Zhou Zhengyi said: "Although it is still unrealistic to break through the title level with Huaxia Type I Spirit Power Liquid, the cultivation speed can be increased a lot. ”

Lin Feng nodded.

Developed from scratch. It's much slower and more troublesome than cracking.

Wen Jing is standing on the shoulders of giants, but Sun Shengren can only rely on himself to slowly explore, and he can't help him in this aspect, the research of science and technology can not be completed in a day or two, after reaching the galaxy level, scientific and technological research can be carried out for thousands of years.

"Is he still researching spiritual liquid?" Lin Feng asked.

Zhou Zhengyi smiled bitterly: "I'm studying the laser cannon." ”

"Uh......" Lin Feng was stunned.

Zhou Zhengyi shrugged: "I persuaded him, but he said that his research on spiritual power liquid was inspired. ”

Uninspired?

Lin Feng laughed and laughed: "It's okay, let him play freely." ”

"That's all it can be." Zhou Zhengdao.

Lin Feng smiled: "Don't be harsh on him. What materials he needs, conditions, as much as possible to meet him. ”

"I understand." Zhou Zhengdao.

Looking at Lin Feng, Zhou Zhengyi said, "How long is it?" ”

"More than two months." Lin Feng knew what Marshal Justice was asking.

"Not over yet?" Zhou Zhengyi's eyes were blazing.

Lin Feng shook his head: "Far from it." ”

Zhou Zhengyi took a long breath and smiled: "I thought that after the mass extinction was over, the crisis on the earth would be resolved, it seems... It's that I'm too optimistic. ”

"It's not a good thing to be optimistic." Lin Feng said with a smile.

"That's all it can be." Zhou Zhengyi said: "What I can do is to help you take care of the rear, so that you don't have to worry about the future." ”

"That's enough." Lin Feng said.

…

Day after day. Month after month.

Lin Feng cherishes every day on earth, because the distance and the separation of his relatives are getting closer and closer. Although he was very reluctant in his heart, he had his responsibilities and obligations, and how much strength he had needed to bear as much pressure as he could, Lin Feng was not afraid, because he knew very well that these were all for the future. For the sake of the planet.

Xiao Yu successfully became his apprentice, the first apprentice.

Lin Feng didn't give him too difficult an assessment, although he wanted to comprehend the Nine-Style Purple Thunder Sword Technique, but there was a lot of room for tactfulness, and comprehension was also comprehension. All comprehension is also comprehension. If Xiao Yu couldn't do it in three months to comprehend the fur, he would naturally not be able to take him as an apprentice.

Although he didn't have much hope, Xiao Yu's sword skills gave him quite a surprise.

In three months, he has fully comprehended the first seven styles of the Nine-Style Purple Thunder Knife Method, and the part of the last two styles has been comprehended, which is already quite good in terms of time and efficiency, of course, this has a lot to do with the similarity of his personality to Xiang Yu, and cultivating the Purple Thunder Knife Method will get twice the result with half the effort.

"I don't have high requirements for my apprentices, you can not be strong enough, but you can't not work hard."

"You must not be a traitor, the eldest husband can do something and not do something, he can do it recklessly, but he must not violate his conscience and do things that hurt nature and reason, understand?" Lin Feng looked at Xiao Yu, who knelt on the ground respectfully, clenched his sword, and was overjoyed: "Yes, teacher." ”

Lin Feng nodded lightly.

For the selection of his first apprentice, he is still very satisfied in general, he can see his former self from Xiao Yu's body, and he also believes that his sister's vision will not be wrong.

…

Time flies.

In the blink of an eye, Lin Feng stayed on Earth for another whole year.

From the return of the Zhan Wu Ji in January 106, to the big wedding on January 1, 107 of the Zhan Wu Ji, and then to the current January 1, 108 of the Zhan Wu Ji, the first anniversary of the marriage, Lin Feng let go of his cultivation time and accompanied his family and Ling'er well.

In his heart, home always comes first.

Relatives are the strongest force in his heart, and if he loses them, then everything he has will be meaningless.

"Brother, next time you come back, remember to bring me the beast eggs~" Lin Yuer said.

"Don't worry, Ah Feng." Lin Zhan smiled.

Mother Ji Ruhua hugged gently and said in her ear: "Protect yourself." ”

"Hmm." Lin Feng nodded, hugged his eldest brother Lin Zhan and his younger sister Yu'er one by one, and finally came to his wife Ling'er, looking at the beautiful face with a strong smile on her face, Lin Feng gently hugged her into his arms, there was no need to say anything more at this moment, a thousand words were in it.

At this moment, time seemed to stand still.

There is not much sentimentality of parting, with the improvement of strength, the life span is getting longer and longer, when the life span is only a hundred years, the separation of one year and two years is very long; But when the lifespan grows to 10,000 years or more, a year or two actually passes in the blink of an eye.

Bidding farewell to his family, Lin Feng stepped into the Hanging Gardens of Babylon alone.

Return to Nemer!
