The Research Institute building of lengwei group is like a hard turtle shell. On the surface, it is not very grand, but the real space used by the research institute is underground.

    Lengtian was very surprised when he received a communication from his brother on Thursday that he was going to come to the Research Institute. He had been waiting at the door early on Saturday morning. Until Lengfeng''s aircraft appeared on the apron in front of the Research Institute, lengtian still felt that it was a little untrue.

    Lengfeng put the aircraft into the space link before running to the place where lengtian stood. Unexpectedly, his eldest brother came out to pick him up so early.

    "Good boy, I thought you said you were coming to brush me." how much his brother hates this institute, lengtian also knows that Lengfeng hasn''t stepped here since he was young, not to mention that he took the initiative to say he''s coming.

    "I just want to see it on a whim." Lengfeng rubbed his nose and said with some guilt.

    "Xiaofeng, are you a second level spirit?" lengtian walked in with Lengfeng, and suddenly felt that the spiritual power emitted by Lengfeng was more mellow.

    "Yes, just promoted yesterday." after soaking in the medicine pool last night, his mental strength finally couldn''t hold down. Fortunately, the time of a week came, and Lengfeng let it go.

    However, when he really became a second-class spiritual person, he knew how big the gap between the two was. Not only did the five senses become more sensitive, but also his spiritual power had a qualitative change. No wonder the students in the college didn''t look up to him.

    "Congratulations, why don''t you say, I didn''t prepare a gift for you."

    "Hey, hey, didn''t I come directly to ask you for it? Just give me a soul armor." now, needless to say, the price of the armor produced by the alliance is almost provided to the military. Other people may not pass the application for a long time. Lengfeng has the cheek to ask lengtian to open a back door for him.

    Listen, but Lengfeng wants the soul armor. Lengtian is still very happy. Does this mean that his brother doesn''t reject the identity of the spirit, "OK, I have a ready-made soul armor. The level is not high enough for you to use level 3."

    Leng Tian thought of a soul armor he tried to make some time ago. Because he tried to make it himself for the first time, the materials selected were relatively simple. However, Lengfeng is only level 2 now, and it is not suitable for soul armor with too high operation level.

    Unexpectedly, the eldest brother was so easy to talk. Lengfeng rubbed his palm and asked, "does the eldest brother have a ready-made mechanical pet, the one who can chat?"

    Lengfeng thought of Xiao a who said he wanted a little partner. That little guy is very talkative. Unfortunately, he is busy studying every time he enters the space and has no time to accompany it.

    "Mechanical beast pet? No." lengtian is a little strange. Lengfeng wants the cute thing that Omega likes, and soon looks at his brother with a teasing face, "it''s not meant to please any Omega!"

    "Ah? Well, that''s right!" Leng Feng wanted to refute, but he could only nod his head and admit it. It''s better to say that he wants to please Omega than to say that he wants to please a mechanical animal pet.

    "Now only ordinary mechanical pets can be seen on the market. In the past, mechanical pet animals were able to live by energy stones. Now the energy stones of the alliance are in short supply, and most of them are used in mecha and warships. Products that need to consume energy stones and have no practical effect, such as mechanical pet animals, have been eliminated."

    In recent decades, the energy mining stars of sea micro galaxies are often destroyed by crazy Zerg and monsters, resulting in an increasing shortage of resources of sea micro galaxies. The crystal nuclei needed by powers are more and more difficult to collect because of the increasing number of crazy monsters.

    Energy mining areas are decreasing. In order to concentrate their strength, the alliance''s energy stones have long been controlled by the forces of major legions. Only those with powers can join the army to get more resources and equipment. Even if there are a small number of energy stones on the market, one of them has been fried to the sky high price of 10000 stars.

    If it weren''t for the Empire, the situation would be the same. I''m afraid the life of the Federation would be even worse. However, resources have been reduced again and again. Sooner or later, the two sides will fight to seize energy mining stars.

    Leng Feng also remembered that the book mentioned that due to the shortage of resources, the federal technology and quality of life were regressing. Suddenly he thought of another question, "does soul armor consume energy stone very much?"

    "Otherwise, why do you think the soul armor of machine armor is only sold to the military? A high-level machine armor can use up an energy stone in four days, and a low-level one in ten days. Now the soul armor you see in your college is just a model." the soul armor they provide to Xingmeng college is only for practice, and has no attack power at all.

    "It''s OK to stop production." so Leng Feng is also calculating in his mind. In the future, he has to save more star coins to buy energy stones. As for the mechanical animal pet, he can only think of another way. Fortunately, he has been able to make class E soothing agent. When he goes to the pharmaceutical association to certify an E-class pharmacist, he can sell it directly on the star network.

    Lengtian saw that his brother had been drooping his head and thought he was unhappy. "If you want big brother to make one for you, but after a while, you don''t have to worry about the energy stone when I''m busy. Can we afford it?"

    Lengwei group has been trading with the military. The energy stone is not as rare as others. It is not a mechanical beast pet. An energy stone can be used for many years.

    Leng Feng looked at lengtian''s side face with a complex look. The big brother always made him feel guilty every time, "big brother, you are too kind to your brother."

    "What''s the matter? Don''t forget that I brought you up when you were a child." lengtian suddenly heard his brother say such disgusting words. He couldn''t adapt for the moment. He raised his hand and rubbed each other''s short black hair to hide his embarrassment.

    "Also said, when I was a child, you were only a few years old, and I would have been tossed to death by you without my grandmother." Leng Feng thought that lengtian in his memory was not so gentle when he was a child. A dead child took his brother to play superman all day.

    "Hehe, you still remember!" lengtian didn''t expect Lengfeng to remember things so long ago. His smile was embarrassed and stiff on his face.

    Leng Feng was very conscientious and didn''t embarrass him any more. "How are you recently? Why do I feel your breath is still very unstable."

    It has been a week since he went to school. Lengtian has been fine by using the soothing agent, but his energy is obviously more violent than others. In particular, he is now more sensitive to the second level mental power, and the agitation in lengtian can''t hide from him at all.

    "Yes?" lengtian didn''t feel much. It seemed that his energy was always more active than others. He was used to this situation.

    "Where did you buy your soothing agent?" Leng Feng always felt that there was something wrong. The energy riot during Leng Tian''s promotion was certainly not accidental. His current state is like a precursor.

    "Cathartic? The cathartic used by our family has always been arranged. Every time we go back to my room, we have a medicine box." although lengtian doesn''t understand why his brother suddenly asked about cathartic, he still has questions to answer.

    "Do you have any with you? Give me some." when lengtian said this, Lengfeng was even more worried. In addition to his grandmother, the Leng family was taken care of by his second uncle and aunt. If that person arranged lengtian''s soothing agent.

    "What do you want a soothing agent for?" Leng Tian looked at his brother with some confusion. His soothing agent is only suitable for gold powers. What does Lengfeng want this to do.

    "I''m learning refining medicine recently. I want to ask you for some to go back and decompose. When I succeed, I''ll pack your dredging agent for you." now I''m not sure if there''s a problem with the dredging agent, Lengfeng can only find an excuse to prevaricate it.

    "The breeze is getting stronger and stronger. I don''t take it with me now. I''ll take it back to the dormitory for you later." every time I come to work in the Institute, lengtian will bring enough soothing agents. It doesn''t matter to take some to my brother for research.

    The research institute sure enough has heaven and earth. After saying these words all the way, they finally came to the floor of the mecha exhibition hall. Lengfeng followed lengtian through the card changing process, and then they saw the place where the legendary high-grade mecha was collected.

    Lengfeng felt that he was like entering a museum. Starting from the first mecha that had been in some years, nearly 100 sets were set up in the whole exhibition hall. This vision is like watching a classic car in the old era develop into a luxury car in the new century, but what is put here is not a car, but a more cool and sophisticated mecha.

    After lengtian''s consent, Lengfeng opened his head and took pictures and videos of the mecha like a hick who has never seen the world. He will like it when he sees Mo Yan next time.

    Leng Tian took his younger brother to see it one by one, and consciously took up the work of a tour guide. He introduced to him the R & D time and performance of each mecha, what events he had participated in and what awards he had won. Leng Feng turned into a reporter and videographer to interview and shoot all the way.

    In the early years, most of them were machine armor. Later, the figure of soul armor gradually increased. Lengwei group has been established for some years. In addition to recording the development history of machine armor, it also records the development track of the world.
