"Where did the origin of life begin, as in the theory of evolution, the so-called 'natural selection, survival of the fittest'? Or is it the so-called 'God made all things' in the mythology of various countries? There are many theories, but for the initial evidence of life, everyone tacitly agrees to one theory - the Cambrian explosion of life.

It was about 542 million years ago to 530 million years ago on the earth's calendar, which is considered to be the beginning of the Cambrian period in geology.

For the long history of life on earth, the appearance of these life forms is tantamount to appearing overnight, which is also the origin of the Cambrian explosion of life, and in these life forms, a variety of new creatures and organs have evolved, especially two organs can be called artifacts in the environment at that time, one is the eye, the other is the spine ......"

On a dreary summer afternoon, Yan Hua glanced at the slides on the big screen in front of the stage, and lamented in his heart: "It's just a few minutes late, and I didn't expect to miss the course I wanted to listen to. ”

However, as an orphan, Yan Hua has always adhered to the attitude of life as it comes.

Although the current class is not the course I want to listen to the most, for Yan Hua, who is very interested in working and studying, every credit, even if he is no longer interested in the current course, Yan Hua still listens carefully to the old professor's class, while staring at the big eyes of the strange shrimp on the slide, while trying to make notes that I don't know if there are any useful notes.

"Buzz~Buzz~" A slight vibration came from his pocket, Yan Hua first glanced at the old professor who was talking in the direction of the blackboard, and saw that the other party had no intention of turning around for the time being, so he carefully took out the mobile phone in his pocket.

"At half past three in the afternoon, 103 of the comprehensive laboratory building, come over to help move a few equipment."

Yan Hua flipped out the message and took a look, but found that it was not the news that his roommate asked to bring food as he expected, but a message from Teacher Zhang from the school laboratory.

"Okay! Roger that! ”

Yan Hua thought about it, it happened that the end time of this class was a quarter past three, and it would take less than ten minutes to put away the books and go to the laboratory by himself, so he should have been in time, so he moved his fingers quickly and replied to the information.

After Yan Hua replied to the message, put away his mobile phone again, and began to listen to the class, but I don't know if it was because he heard that he could access the test equipment he had never seen before, or because the weather was getting hotter again, Yan Hua felt that his attention gradually flew away from the class.

"Bell bell bell ~" The bell for the end of class finally rang, Yan Hua quickly packed up the textbooks, ran out of the classroom with a smoke, and went towards the comprehensive laboratory building.

"I wonder what kind of high-tech test equipment it is this time?" Yan Hua ran all the way to the comprehensive laboratory building, thinking with anticipation, "Our university is also one of the best schools in South China, and the test equipment should not be much worse this time, but I just hope that this time Mr. Zhang can let me touch it with my own hands in addition to letting me observe the debugging." ”

Maybe it was because the weather was too hot, and it was another strenuous exercise, and by the time Yan Hua came to the gate of the comprehensive laboratory building out of breath, he was already sweating profusely.

"Whew! Odd! Although my body can't be said to be at the level of an athlete, I have been working all year round, so why is it like this? Yan Hua carried his schoolbag, put his hands on his knees and gasped, and couldn't help but have some doubts about his physical fitness.

"Yan Hua! This way! Just when Yan Hua was still breathing, he suddenly heard someone in the experimental building shouting about himself, and when he looked up, it was indeed Teacher Zhang.

Yan Hua saw Teacher Zhang waving to him, and there were several one-person-high cabinets parked beside him, guessing that the test equipment contained in it was probably the test equipment that Teacher Zhang mentioned before, so he couldn't help cheering up and replied: "Here!" ”

"Huh! It's pretty punctual! I was just thinking that the teaching building is not close here, and I am afraid that you will not have time to come? When Teacher Zhang saw Yan Hua walking to his side, he didn't think that Yan Hua's clothes were completely soaked with sweat, so he raised his hand and patted Yan Hua's shoulder, and said with a smile as if he was treating a junior.

Yan Hua looked at the middle-aged man in front of him and said with a hippie smile: "That's!" This is a task assigned by you, Mr. Zhang, how dare I slack off? ”

Seeing Yan Hua's exaggerated expression, Teacher Zhang couldn't help but smile and scolded: "Don't come with me for this!" I've never seen you so active, but I think you just want to see the new test equipment this time. ”

Seeing that his attempt was exposed, Yan Hua was not embarrassed, but he smiled, and Teacher Zhang also smiled when he saw Yan Hua like this, turned sideways to a wooden box beside him, held up a corner and said to Yan Hua: "Okay! Don't talk about it, come over to help, try to put the instrument away as soon as possible and then debug it preliminarily, and invite you to have a meal when you're done. ”

Seeing this, Yan Hua also walked to the opposite side of Teacher Zhang, stretched out his hand to hold up the other side of the wooden box, but found that although the weight of the box was not light, it was not too heavy.

Yan Hua couldn't help but ask, "Teacher Zhang, what kind of test instrument is this time?" It seems that the volume on the outside is larger than the previous fluorescence microscope, but the weight is much lighter. ”

The teacher cautiously walked over a step and replied: "You are asking the wrong person this, this time the instrument is not handled by me, but Mr. Ling received a project from the Chinese Academy of Sciences, and moved it directly from there, so he didn't ask outsiders to help carry it, it all depends on the school itself." ”

"Teacher Ling?"

Teacher Zhang was carefully carrying the instrument in front, and after hearing Yan Hua's question, he casually explained: "Yes! It is Mr. Ling, who just arrived at our university this year and has already obtained a double doctorate degree at a young age, and now he seems to have an elective course called "Modern Biological Organ Evolution and General Technology" in his sophomore year. ”

Yan Hua was stunned for a moment, and then realized that the course that Teacher Ling and she taught in Teacher Zhang's mouth seemed to be the elective course that she missed.

"Sure enough, modern biotechnology is more suitable for me, and I can get in touch with the latest technology products just after the beginning of school." Yan Hua couldn't help muttering in her heart after hearing Teacher Zhang's words, and she was even more annoyed that she was lying in bed on the morning of the course selection.

Teacher Zhang naturally didn't know Yan Hua's inner activities, and said to himself: "Teacher Ling is now debugging the preliminary equipment in the laboratory, just wait for us to move these big guys in to debug no problem." You kid has an eye for luck today, not only has you come into contact with the new equipment, but you can also see the big beauty up close! ”

In the face of Teacher Zhang's ridicule, Yan Hua felt a little embarrassed, because Teacher Zhang's words reminded him that the real reason why he was in bed on the morning of choosing a class was actually because he happened to meet Teacher Ling at school the afternoon before yesterday, and then had insomnia at night.

Thinking of this, Yan Hua's face gradually warmed up, and at the same time, he had some small expectations in his heart.

"Mr. Zhang, I have already debugged the preliminary equipment, and now I just need to link the living security warehouse...... Hey? Who is he? Just when Yan Hua and Teacher Zhang were about to arrive at the door of the 103 laboratory with the suitcase, a nice voice suddenly came from the laboratory.

Yan Hua looked over the wooden box in front of him, who knew that he couldn't take his eyes off after just one glance, his hair coiled up like a dark cloud, his delicate and flawless face like jade, and under his slender and beautiful eyebrows like willow leaves, there was a pair of autumn eyes hidden under the glasses, and his slender figure was matched with a white coat, which was a little less cold and arrogant than the last glimpse, but more intellectually beautiful.

As a modern person, Yan Hua has also come into contact with many beauties known as goddesses on the Internet, but Yan Hua can pat his chest at this time and say that the one in front of him is the real goddess in his mind.

"Oh! He is a work-study student in the school, named Yan Hua, and I usually ask him for help in the laboratory, so this time I asked him to come over to help. Teacher Zhang turned his back to Yan Hua and introduced to Teacher Ling.

"Hello Teacher Ling! I'm a sophomore...... I'm here to help...... Ahh Yan Hua reacted at this time, and wanted to salute Teacher Ling, but forgot that he was still carrying the box in his hand, and he felt a little hurried for a while, which also made Yan Hua's face even redder.

Maybe it's an illusion, after Teacher Zhang introduced Yan Hua, Teacher Ling's eyes when he looked at Yan Hua had relaxed a lot, and when he saw Yan Hua's embarrassment again, the corners of his mouth couldn't help but bend slightly, and he no longer looked at Yan Hua, who was already comparable to a monkey's butt, and nodded at Teacher Zhang: "Hmm! Thank you for your hard work, Mr. Zhang, I've vacated the place, let's move things in! ”

Teacher Zhang responded, signaling Yan Hua, who was silent because of shyness, to follow and then stepped into the 103 laboratory, as soon as he entered the laboratory, Yan Hua found that the scene in the laboratory was very different from the layout in his previous impression.

Laboratory 103 has a small barricade room for biological specimens, so even though the sun is blazing outside, the inside of the lab is still cold, no different from usual.

The change is that the tables, chairs and benches that were still in the laboratory are gone, and the fluorescence microscope that was originally placed next to the laboratory podium has been moved to the corner, freeing up a large open space.

In the clearing, there were now three devices that looked like medical monitoring equipment, and there was a gap between them about two adults side by side, and some cables protruding from the instruments were arranged in an orderly manner, apparently to be connected to the so-called life-support pod in the box in front of him.

The commissioning and installation work is naturally completed by Mr. Ling, and Mr. Zhang and Yan Hua are only responsible for removing the wooden planks of the life-support cabin and putting it in the designated position, during which the position must be adjusted and fixed under the guidance of Mr. Ling, which can be said to not stop for a moment.

Taking this opportunity, Yan Hua saw the appearance of this life support capsule clearly, but to Yan Hua's disappointment, the life support cabin in Mr. Ling's mouth was very different from what he had thought of in science fiction works before, neither like the cylindrical incubator filled with the so-called nutrient solution in Resident Evil, nor the half-open cockpit-like appearance in Star Trek, but instead looked like a metal capsule standing on the ground.

If it weren't for the fact that Mr. Ling kept connecting the cables to this "capsule" and debugging them one by one, there were constantly high-tech signal lights on or off on this "capsule", and Yan Hua wouldn't have been able to figure out what kind of life support cabin this thing was.

"That's it! The next step is to test the stress start-stop device. Teacher Ling took his eyes off the light screen in front of him, glanced at Yan Huawei who was standing in front of the life support cabin, and smiled slightly, "Next, I want to ask classmate Yan for a favor, I don't know if it's okay?" ”

Facing the goddess's request and looking at the goddess's smile, Yan Hua suddenly felt full of energy, and tried to straighten his back and said, "Teacher Ling is polite, if you have anything to help, just say it." ”

Teacher Ling saw Yan Hua's posture like a male peacock, and the smile on his face became a little more obvious, and said: "It's nothing, I will start the hatch of the life support cabin for you to lie in in a while, and then turn off the external power, then you just need to knock the position of the hatch in front of you to see if the hatch can be opened." ”

"This is to test the backup safe energy of the instrument, which will not be dangerous." Teacher Ling added softly.

Yan Hua already felt that his brain did not belong to him when he saw Teacher Ling's smile on him, and he already had a longing for this high-tech machine that came out of the Chinese Academy of Sciences, so he nodded without thinking about it and walked into the wide open hatch in front of him.

But Yan Hua didn't expect that it was this nod that made his life change even more drastic than earth-shaking.
