David. Charles dedicated most of his life to biology, and when he was 7 years old, the first sight of the floating spots under the microscope doomed him to be trapped in this life, meditating in the genetic sequence at the age of 15, and rampage between cells at the age of 30.

At the age of 40, he made a name for himself in the world of biology, and now, scholars from all over the world gather in this lecture hall just to listen to a David class, and in just two hours with this slightly rickety 55-year-old bearded old man, he can blow in the laboratory with his colleagues for months.

David slowly closed the notes, after a period of silence, thunderous applause, the chairs of the shaking classroom clicked, in the eyes of the students in the audience, this is a feast for the biology community, and in David's eyes, this is at most a boring recitation, annoying lights, boring words, this kind of applause rings 10,000 times is meaningless, David did not say thank you, just bent his waist, and slowly walked out of the noisy classroom

Fifteen years ago, the 40-year-old David was already a rising star in the field of biology, like an all-knowing and all-powerful man who conquered the criticism of countless predecessors in the industry, however, he was about to embark on the pinnacle of academia, but he stopped at one question, the blind spot of evolution, a demon in front of ancient and modern scholars, a mystery without answers... The origin of mankind, the blank period of 150w years seems to be a terrible black hole, which cannot be entered or escaped.

As usual, David walked into that quiet café at 3 p.m., ordered a cup of coffee in the most inconspicuous corner, and the sunlight through the frosted glass spread out on the tabletop, mingling with the aroma of coffee, David liked to think in such a hazy atmosphere. Next week is the birthday of his uncompetitive son, but David doesn't want to bother with this at all, in his eyes, anything other than academic is useless.

The coffee here is very good, a little bitter, but every sip can leave a strong aroma, no need to struggle to aftertaste, enough to refresh. David took a sip, licked his lips, and opened the notebook that had followed him for many years, the fluffy leather wrapped in yellowed pages, and the scribbled handwriting recorded David's 15 years of almost crazy pursuit of answers to the origin of mankind, from pride to confusion to despair. Now that he was old, his brain, which had been spinning for more than 50 years, was overwhelmed, and David knew that in a few more years, his genius mind would grow darker and darker, and he would never again be able to touch the secret that no one had ever set foot in.

David was unwilling to give up, only the answer to the origin of mankind was worthy of his brilliant life, otherwise, he would be nothing more than a second Darwin, another failed coward.

It was getting late, and on another fruitless afternoon, David put away his notes in frustration and was about to get up, when a woman sat in front of David,

She claimed to be a biology professor, a student of Dr. C, of course, David had never heard of Dr. C, but in conversation with the girl, David found that many of Professor C's views were very bold, and vaguely, he seemed to have grasped a key to open the treasure. Just at the end of the conversation, the girl handed David a letter. In the letter, Dr. C claimed that he had some ideas about the origin of mankind and wanted to communicate with David, and David happily agreed

......

......

Just as David was looking forward to meeting Professor C, an unmarked military helicopter flew into a no-fly area of the Indian Ocean. A deafening roar was accompanied by churning water, and a helipad rose from the sea. The helicopter slowly descended, and Dr. C stepped off the plane. More than a dozen task forces armed with nuclear bombs quickly surrounded the unarmed hunchbacked uncle. After some instrument testing, the soldiers escorted Dr. Cai into the huge underwater fortress.

3,500 meters below the surface of the water, 1.5 meters thick titanium-rich metal is under enough pressure to destroy any hope, there is no light, no sound, more than 400 people work in this impregnable underwater prison, just for one thing, looking at an old man.

As the name suggests, this man is very old, too old to be imagined by everyone. In his almost endless life, the old man has never been more excited. In the last 55 years, the old man has been in a state of euphoria all the time, sometimes laughing, sometimes crying, pulling off his long scabbed hair one by one, suddenly jumping up and throwing himself to the floor, or frantically hitting the steel wall for weeks in a row, his eyes bloodshot without sleeping, and his long-term almost masochistic behavior only left a shallow bruise on his body.

Dr. C walked through the hallway full of monitors and pressure sensors to the deepest part of the room, and after a full-body scan, the door opened, and the old man in the room was roasting his right hand on the fire, his hair covering his face, but not the excitement that burst from his scarlet eyes. When he found Dr. Cq coming in, the old man frantically used his hands and feet, crawled to the doctor, pointed to his right hand, which was still steaming but not burned, and said, "Behold, the skin is red, and it hurts." After saying that, he laughed wildly, rolled on the ground, hit his head on the floor frantically, and threw tears and saliva on the ground.

Dr. C took out a watch, pointed to the shortest hour hand and said, "There are 24 hours left, and this needle turns twice."

The old man got up from his knees from the ground, took the watch tremblingly, stared at the dial and let out a beastly cry, muttering an incomprehensible language, his tear-soaked hair tangled and leaking out of the old man's face, much like David Charles.

The sound of the old engine of the bus was drowned out by the heavy rain, and the roads in the suburbs were always muddy in this weather, and the six-hour drive and the heavy rain did not affect David's anticipation in the slightest, and a voice told David that this conversation was the key to unlocking the secret of human origins. When the doorbell rang, it was Dr. C, who had crossed half the world to meet David in such a short period of time, and of course, no one would have imagined that since the moment David was born 55 years ago, he had been designated as an extremely important containment object, designated S-021.

David omitted all politeness and eagerly began Dr. C's academic discussion, and the conversation gradually got better, until Professor C made a point about the origin of human intelligence, and David was shocked and speechless.

The evolution of organisms itself has no direction, and accidents will become inevitable in a long period of time, and the surviving organisms will bring the mutated genes to the next generation, and the survival of the fittest will be shaped into a vector line similar to evolution, but what if there is a guide that has been formed in the evolutionary journey, a finished product that has undergone a long evolution, and a brain and wisdom with a huge brain capacity stand in front of the creatures at the evolutionary level. David's mind seemed to explode, because if there would be no fork in the road, and there would be no accident, a guide would turn everything into a necessary result, and all doubts would be solved. But another question arises, how did this wizard come about? David cast a puzzled look at Professor C.

Professor C did not explain, but asked David to make a choice, abandon his current life, search for the ultimate answer to the origin of humanity, or like all losers, bow his head and admit defeat on the road of knowledge. David didn't have the slightest doubt about this strange choice, the answer that he had been entangled for a lifetime was in front of him, and he naturally wouldn't give up and chose the former.

Professor C took David to open a corner wooden door, in the center of the small room was a strange old iron machine similar to an armchair, the back of the chair was inlaid with this dial, rusty, a few hands trembling and about to fall off, Professor C motioned for David to take off his clothes and sit on, David did so with a hint of doubt, Professor C turned around and pulled a switch similar to the electric switch of the last century, the dial slowly rotated, faster and faster, shaking the whole machine as if it were about to fall apart, David wanted to stand up, but was pressed on his seat by an invisible pressure, a puff of smoke slammed, the vibration stopped, and the machine scattered to the ground, and David was gone.
