Until he felt that the energy in his body was full again, Lingfeng found that his mental power seemed to be more condensed than before. Although this feeling was not very obvious, there were still benefits to regular exercise.

In order to engrave the inscription dominoes, the two stayed in the space for another day. As soon as they left the space, Lingfeng’s light brain sounded. Seeing that it was Lingtian calling, they quickly clicked to answer, "Big Brother?"

"Where did you go, Xiaofeng? There is no signal with Moyan's communication channel." Lingtian couldn't help but ask curiously as soon as he connected. He has been looking for both of them for a day.

"We are in the isolation room, brother is looking for something to do with me?" Ling Feng changed the subject with some guilty conscience.

"You and Mo Yan's mecha have come out. I just want you to come to the research institute whenever you have time." The new mecha Lengtian's tone was a little excited.

"So fast? Mo Yan and I will be over tomorrow." Lingfeng was a little surprised, but he didn't expect that Lingxi Cheng and Lingtian would make the mecha in more than two months.

"What's the matter?" waited until Lingfeng hung up the communication stranger before speaking.

"Big brother said that our new mecha has come out, let's go to the research institute tomorrow." Lingfeng said to Mo Yan with bright eyes. The diamond essence came out in the hands of the old man and the big brother. I don't know what it will look like. Listen His eldest brother's tone should be better than that of the imperial batch.

"Okay." A light flashed in the eyes of Mecha Mo Yan.

The next day, Lingfeng went to see Grandma Ling, and then went to Jiang’s house with Mo Yan. Maybe it was Monday because of Monday, and because his uncle and Jiang Yue were not there, Ling Feng gave two little tortoise shells wearing red ropes. Aunt, Ling Lan liked these two small and cute tortoise pendants, and immediately put them on the baby's neck.

Looking at the two babies wearing dominoes made by themselves, Lingfeng felt a sense of indescribable satisfaction. He played with the two little guys for a while before leaving from Jiang's house.

It was almost noon when they arrived at the Lingwei Research Institute, but the two of them didn't bother to eat, and followed Lingtian to the mecha room to see their new mecha.

They have returned to the Federation for more than two months, and Lingtian hasn’t seen Lingfeng for more than two months. I was really shocked to see it today. The breath on my brother's body is quite different from before, "Xiaofeng, Are you promoted again?"

"I just promoted the previous two days." Although the aura on her body has been reduced, she didn't notice it in Aunt Jiang just now. Unexpectedly, the eldest brother discovered it at a glance, and Lingfeng did not hide it.

When he got the affirmative answer, Lingtian's mood suddenly became a bit complicated. He was sure that the time for Lingfeng to reach the fifth rank was later than him. He is still at the elementary level now, but his younger brother has directly broken through a rank position. This kind of advancement speed really makes him. People feel desperate, remembering that his father once told him that his younger brother is a sss-level talent. At this moment, he can truly appreciate the difference in talent.

After Lingtian sighed inwardly, he remembered another thing, "I heard that you traded the formulation of the fertility aid with the Federation?"

"Well, the eldest brother stays in the research institute, the news is still very clear." Lingfeng nodded calmly, anyway, it is not a big deal.

A few days ago, the federal government was in charge of contacting him to purchase fertility aids and found him, and Lingfeng took advantage of the trend to mention his intention to trade the formula. Although the federal government's request to Lingfeng was unexpected, it was the temptation of the fertility formula. It's still very big, and after discussing it, I quickly agreed.

"Actually, my father and I have other methods. You don't need to exchange such precious formulas." My brother used the fertility formula for four places to go to the Tiandi Galaxy. This incident surprised Lingtian at the same time. I felt ashamed, and felt like I was holding back my brother.

The result of the final negotiation between the Empire and the Federation was that 50 people from each side were sent to the Tiandi Galaxy. Although grandma helped them solve a problem, it was still a bit difficult for the 50-placed family to occupy four.

"It's not too precious. I was able to sell such high prices on the black market because I was in the empire, and the things were rare and expensive." Inheritance, a recipe is sold as soon as it is sold.

"Although this is the case, the formula of the medicine that can improve conception is still very rare." Lingtian doesn't know the medicine, and the fertility agent seems to him to be very magical.

"Actually, the fertility agent is not so mysterious. Its principle is to remove the rich energy and impurities in the Mi Qingzi and the egg, so that the two can be more easily combined. In the final analysis, it is to return the two substances to the most primitive form. As soon as omega is combined with heat itself, the pregnancy rate is very high. On the contrary, although beta-taking this drug also increases the probability of conception, the effect is not as obvious as omega." Lingfeng has already thoroughly studied fertility agents, but did not feel that How mysterious.

He talked eloquently here, but Lengtian, who was walking with him, was blushing and sighed inwardly, his younger brother was indeed a pharmacist, and he didn't change his face when he talked about this kind of thing.

Mo Yan is also the first time he has heard of the reason that fertility agents can increase conception. Sure enough, he said that, the mystery of fertility agents has also been unveiled. If other senior pharmacists hear this, it is estimated that they will pass again. A formula can be developed soon.

Several people were talking about Guangnao's electronic notification sound suddenly sounded, and when Lingtian saw the name displayed on Guangnao, he was a little helpless, but he still answered, "Hello, I am Lingtian."

"Marshal Liu, fortunately, my father is still in the R&D room... so... please wait for me to come right away." Lingtian said a few words to hang up the call, and said to the two apologetically, "Look. I can't accompany you to see the mecha. Xiaofeng knows where the mecha room is. Go ahead with Mo Yan!"

"Is the eldest brother in a hurry?" Lingfeng seemed to have heard Marshal Liu just now. These marshals of the Federation are hard to see on weekdays, and they don't know why the other party suddenly came to look for the eldest brother.

"Those people in the Legion knew that the ore we exchanged had developed a batch of mechas, so they wanted to buy them from Lingwei. My father had already said that this batch of materials would not be sold, so they invited the old man from the family out. I can't wait to buckle a frame back from Lengwei. My father was so annoyed that he hid in the R&D room." The burden of his father hiding and receiving these people fell on him alone, and Lengtian could only bite the bullet and refuse.

"Then eldest brother, you should be busy, let's go and see it by ourselves." Lingfeng didn't expect that it was because of this incident. Hearing Lengtian's tone accusing him that the old man was hiding, he still felt a little want to laugh.

However, the number of mechas that can be made with this batch of materials is limited, and they have other plans. It is impossible to sell them. Moreover, Ling Wei has a contract with the current three legions. If the three legions are sold, they can’t care about one or the other to avoid injury. To be kind.

Seeing that Lingtian hurried away, Lingfeng continued to the mecha room with strange words. The mechas of the two of them were placed alone in an empty room, and the two mechas were standing side by side, not yet painted. 'S body is still the cold original metal color, just like the soul armor that Lingfeng had given to Lingfeng.

However, these two are obviously not comparable to Lengtian's trial work, regardless of the design material details are much better than Lengwei's latest mecha.

Mo Yan was attracted by the mecha in front of him, and couldn't help but reach out and touch it, and suddenly felt that he couldn't put it down.

The two played a battle with the new mecha in the mecha room. Lingfeng found that compared with this soul armor, the one he used before could be called an entry-level one. If this soul armor appeared a year ago In front of him, Lingfeng estimated that he couldn't control it either.

Accompanying Mo Yan tried the feel of the new mecha. Seeing that he still wanted to practice for a while, Lingfeng left the mecha room alone and went to the research and development room to find Ling Xicheng.

Although Ling Xicheng was trying to avoid trouble, he did have something to do. When Lingfeng arrived in the research and development room, he discovered that Ling Xicheng was testing the feasibility of the new starship design. The people in the entire research and development room were very happy. Busy, seeing that he just nodded and greeted each other in a hurry, Lingfeng felt that he had come at an untimely time.

Just when Lingfeng was considering whether to withdraw first, Ling Xicheng stopped him, "Xiaofeng, why are you standing there."

"Dad, I think you are busy, or wait until you are finished." Lingfeng scratched his head and said.

Just now, Ling Xicheng noticed the changes in Lingfeng at first glance. Although he was surprised, he didn't show it on his face, "Go to my office."

Just as things came to an end here, Ling Xicheng asked the associate professor in the R&D room to help him take a look, and he took Ling Feng back to the ground floor office, "Have you seen the mecha?"

"Look, I just came from the mecha room. The performance of the new mecha is good. It is much more flexible than what we saw in the empire. Mo Yan will still be reluctant to let it go." The smile deepened.

Mo Yan seemed very excited today, just like a kid who just got a new toy.

"You like it." Seeing his son's happy appearance, Ling Xicheng couldn't help but smile a little. He called the door of the office and then asked, "I heard that you used the formula of the fertility agent to exchange four places with the Federation?"

"Yeah." Lingfeng sat down in the swivel chair in front of the desk, "Anyway, I'm going to the Tiandi Galaxy and leave the formula behind. People in the Federation say that in the future, the fertility agent will be strictly controlled like the awakening agent."

"You think it's okay." When Ling Xicheng heard his son say this, he was relieved and a little bit reluctant. "Is there anything wrong with you coming to see me?"

"It's something." Lingfeng took out a potion box and pushed it in front of Ling Xicheng, "There are four A-type heavenly longing potions here. They are potions that can help the sixth-level ability break through the barrier and advance. Everyone can only If you take it once, if you fail, this medicine will no longer be effective, so use it carefully."

"This potion can really help the sixth-level ability person to break through? How could you have it?" Ling Xicheng almost stood up when he heard Qing Lingfeng's words.

As the empire exchange team came back for a long time, there was a lot of rumors about Lingfeng selling yang potions in the empire. Seeing that Lingfeng took out the potion box, he thought that he had made some weird potion. It came out, but I didn't expect it to be this kind of medicine that was even worse than the source-breaking agent.
