For a self circulating ecosystem, the importance of a producer who can adjust the yield according to needs is beyond doubt. Under the coercion and inducement, plant spirits can blossom and bear fruit in one day.


    With the self circulation system of fertilizer, there is no pressure to establish a small ecosystem, and there will be no such situation as wandering around the earth, which can not establish a complete ecological cycle without the whole planet.


    Five hundred cubic meters of space, converted into a size of about 8 × eight × The cube space of 8 is still a little large for the current satellite, but this volume of storage space can be manufactured. Although the cost is frightening, it can achieve the goal of one-time and integrated transportation of the ecological module to space.


    In such a conversion, it''s not difficult for them to escape Douluo, but Chengying didn''t tell Xuedi all about it. She just said that he had a way back. Just like Xuedi, she won''t trust Chengying without reservation, and so does Chengying.


    "Well, please test your body data. We will customize your school uniforms according to the data." Luo Shan led them to a physical examination room.


    Naturally, the first measurement is height and weight. Douluo mainland does not have a weight scale. The principle of lever is still known, and the platform scale is relatively accurate.


    Soul masters are a profession that doesn''t taboo their weight, because most soul masters have a good figure, and Ma Hongjun is out of the question.


    So the test teacher directly reported the height and weight


    "Wu Changsheng is 1.71 meters tall and weighs 67 kilograms."


    "Lintian Qian Xun, 1.68 meters tall, weighs 51 kilograms!"


    "Ah! Damn, it''s more than a hundred kilograms! "


    "Why is the pound here as heavy as yours?" Ice emperor asked on the spirit channel.


    This is a private channel with the studio.


    "I don''t know. This may become the largest academic pit in history. One meter on the earth is one thousandth of the distance from the equator to the north pole, that is, one thousandth of a quarter of the earth''s circumference. Therefore, some people say that they travel 80000 miles a day.


    As for Douluo... This is an academic pit. Douluo is about the same size as the earth, or the same, so the meter here should also be calculated according to one millionth of the equator to the North Pole.


    So the conclusion is quite puzzling. Who formulated this set of measures? I also want to know that it may have something to do with the guy who pit the cloud herders and turn them into soul beasts. "


    "Wait, you''re talking about length units! What I just asked was Jin? " Ice emperor''s reaction was half a beat slow.


    "Little fool! Think about how the unit of weight came from? " The film broke her head.


    "Ah... Forget, as long as the box is one tenth of a meter square and filled with water." The ice emperor stuck out his tongue.


    "Next, Cheng Xue, height... Er... 1.25 meters, weight 25 kilograms, children, are you also an exchange student?" The physical examination teacher has a strange expression.


    Anyone would be surprised to see six-year-old Laurie appear in the team of exchange students.


    "Yes! Uncle, look! This is my student ID card! " Said snow emperor also winked at the physical examination teacher. Looking at the skillful cute action, it was obvious that he was a recidivist.


    "Does she usually do the same?" Chengying whispered to the ice emperor.


    "How do I know? I haven''t been to the human world with her." The ice emperor''s face was shocked by the spirit.


    "Next! Chengbing, come to uncle. Yes, don''t move on the scale. OK! He is 1.31 meters tall and weighs 29 kilograms. "


    "Next, the photographer, um... Are you from the same family? All right, this way, let me see! He is 1.29 meters tall and weighs 27 kilograms. There are no other children! "


    ……


    "Hahaha! I''m taller than you! " The ice emperor stretched out his hand and touched Chengying''s head with the same expression as his big sister.


    "Damn it! It doesn''t grow as fast as diced beans! Girls really develop early! HMM... wait, if the human shaped Xiaobing is not xiaodouding, isn''t it possible... "Looking at the shadow with his face gradually becoming salty and wet, if the ice emperor can do it, he will press him into the wall.


    "All right! The physical data test comes here first, followed by the strength test. The college will arrange corresponding teaching programs for you according to your strength, so please don''t keep your strength. " Luo Shan said, releasing the soul ring.


    Two yellow, three purple and two black are not the best ratio, but the cultivation of soul saint has been very strong in this era.


    "Everyone can attack me, and I will give an evaluation according to the attack intensity."


    "Lintian! According to the student number, you come first! "


    When she was called to her name, even if there was a good figure, she came out and saluted Luoshan, politely said, "I''ve offended!"


    After that, he picked up a thick rocket on his shoulder, pulled the trigger and brushed it without hesitation! When the rocket shot out, the people in Luoshan were stupid and rolled to avoid for the first time.


    In the roar, an ancient tree with a history of 300 years turned into fragments. Luo Shan touched the cold sweat on his forehead and said, "I didn''t let you attack with hot weapons! Use martial spirit! Wu Hun, do you understand? " Luoshan roared.


    After the first mainland high-level soul fighting competition, the misunderstanding that the Duke of tulip accepted the family of rockets and artillery gradually disappeared. Luoshan naturally can see what rockets are.


    Although soul masters are disgusted with this weapon, they have to choose to use it because of their strong crisis.


    "Oh... I see. I''m sorry." Lintian apologized obediently and released four soul rings, two yellow and two purple. At the same time, white ears and tail grew on her head and behind her. It looked like a white fox. Of course, it could also be a Samoye


    This time her attack was much more regular. The two tails were thrown as darts, and there was a big gap in power compared with rockets, which was easily resisted by Luoshan.


    "It''s very good. I have the strength of grade 5 at least. Work hard. I can assess the qualification of the inner hospital by the end of this year. Next!"


    The performance of the next students was not very satisfactory. After all, Shrek college had just been established, and there were not many talented students enrolled. Elder sister Lintian was already the most talented.


    This can''t help but make Luoshan feel a little proud. In terms of the quality of exchange students, they still have the upper hand in Tiandou Royal College, which is a matter of face!
