"So now we've discovered two unknown enemies.
One intends to destroy the world, and the other intends to save it. They chose our capital as the battlefield, resulting in tens of thousands of casualties among our people!"
Rex suddenly stood up and said in a loud voice,
"Now, who can tell me where these two unknown enemies are?
What will their next move be?
This time, we've suffered more than 60,000 casualties. What about next time? Eighty thousand? One hundred thousand? Or do we have to sacrifice all our citizens?"
The CU agent beside him whispered,
"Maybe we only have one enemy?"
"No!"
Rex Lee stared at the other person seriously and said,
"No matter whether he's trying to save the world or the earth, when he chose our country as the battlefield, he became our enemy!"
"What other clues do we have now? I want definite ones! The real enemy, not that invisible and intangible devil!"
The agent beside him stood up helplessly and said,
"On the battlefield, the high temperature of the thermobaric bomb basically destroyed all possible clues. We found the possible origin of them from the six robots they left behind."
It was a tiny steel stamp mark inside the robots after they were completely disassembled;
"Laiyang Steel Pipe Factory."
...
"Mr. Song, we're here."
Hearing this, Song Han, who had been deep in thought with his eyes closed, shook his head, which was still a bit dull from the lingering effects of alcohol and hadn't fully sobered up. He got out of the car, and an old and somewhat dilapidated factory building came into view.
"Laiyang Steel Pipe Factory."
Standing at the gate of the factory area, Song Han looked at the sign above and remained silent for a long time.
"What's wrong, Mr. Song?"
Song Han came back to his senses and said out of the blue,
"I always feel that this factory and I seem to have a special connection."
Saying this, Song Han shook his head and followed Luo Xiang inside.
"By the way, how long do we have to follow him?"
After traveling thousands of kilometers from Shancheng to Dongshan in a day, the members of the Third Squad looked at the figure walking into the factory with a lot of questions in their minds.
"Until he goes abroad."
Number Three rubbed his eyebrows wearily. In contrast to the target who was picked up and sent by car all the way and could sleep soundly on the plane, their team had been staying up all the time with their nerves highly tense.
The team member beside him shook his head and said,
"Can't we just deport him directly? Look at what he's done all day. He went to Shancheng to drink and then came to Dongshan for inspection.
He just looks like an ordinary rich kid."
"By the way, why did he have to go to Shancheng to drink with that chef?
Isn't the barbecue in Dongzi attractive enough?"
Song Han's actions not only puzzled them but also made Wang Wei in the newly established Category III Command Center of Country X highly nervous due to Song Han's strange behavior.
When Song Han suddenly returned to the country, Wang Wei even thought that there was some crisis in the country, which made him mobilize the entire military region in Shancheng.
Although it turned out to be a false alarm in the end, as long as Song Han didn't leave Country X, Wang Wei didn't dare to relax his mind.
At this time, Song Han didn't know that he had been expelled from the human race by Dongda University. At this moment, he was inspecting this production workshop that had just been put into use not long ago.
This was a huge workshop covering an area of hundreds of thousands of square meters.
Inside the workshop, one confusing piece of equipment after another was constantly running, making a harsh sound like tearing tape, "sizzle sizzle".
Workers wearing anti-static suits fixed the prepared square high-oriented pyrolytic graphite plates with a side length of 20 centimeters on the assembly line from the raw material inlet. As the assembly line turned, the graphite plates were sent to the separation port. Then, a substrate coated with glue was pressed tightly underneath. When the assembly line started to turn and the substrate began to rise, the harsh tearing sound started to ring out continuously.
The two assembly lines flowing in opposite directions at both ends kept repeating the tearing process on the substrate that had torn the graphene sheet for the first time. In fact, the assembly lines that filled all the space in this huge workshop alternately were just one line.
In their continuous operation and alternation, they repeated this tearing process two million times.
At the end of the assembly line, beside the feeding port of the graphite plate, the substrate that had been torn two million times was automatically heated by 20 degrees and then soaked in the nearby water tank.
After being oscillated by ultrasonic waves for a while, it started to flow again. After being evenly sprayed with glue for replenishment, it entered the cycle process again.
The graphene flakes floating in the water tank accumulated at a visible speed in this flow.
Luo Xiang looked at Song Han, who had a serious expression, and asked in confusion,
"Boss, it's just some graphite powder. Is it really necessary to be so troublesome?
To rush the construction period, this production workshop cost us nearly one billion. Normally speaking, for such a simple assembly line of machines, a cost of 300 million would be considered high."
"The simplest is always the most efficient."
Ignoring Luo Xiang's complaint, Song Han looked at the nearly ten grams of finished products separated out in a short while and nodded in satisfaction.
This assembly line was designed and formed by Song Han after thinking for a long time when the system issued a task because he wanted a kitchen knife that could cut through iron like mud.
Compared with many large-scale preparation methods of graphene mentioned by the system, such as organic synthesis method or chemical vapor deposition method, etc.
Based on the processing accuracy and production capacity at the end of 2008, unless he could patiently break through all the paths one by one.
Otherwise, this simple assembly line was the world's first large-scale production equipment for graphene and also the only assembly line with the ability to process molecular structures for mankind.
The van der Waals force inside the graphite plate that had been repeatedly pyrolyzed and processed by high orientation had been destroyed. When it was torn for the first time on the assembly line, the high-pressure adhesion of the machine further destroyed the van der Waals force inside the graphite plate.
Spraying super-high-viscosity cyanoacrylate evenly on the constant-temperature substrate, using the adhesive force of the glue, which was another form of van der Waals force, to destroy the van der Waals force between the graphites of the high-oriented pyrolytic graphite plate was a bit like using magic to fight against magic.
It was the same method used by the person who first discovered graphene, a two-dimensional material, but Song Han further sublimated this method and upgraded it all with the existing top processing technology.
With the combination of these two aspects, the processing process that theoretically required three million times of repeated tearing was finally shortened to two million times.
Finally, in the highly hydrogenated water, the graphene on the glue substrate was peeled off by ultrasonic oscillation.
At this time, the more regular-structured graphene would naturally float on the hydrogen-rich water with the smallest buoyancy on earth currently, while the graphene whose layers did not reach the standard would naturally sink under the agitation of ultrasonic waves.
Song Han pointed to the nearby water tank and said,
"All the staff around this hydrogen-rich water need to pay attention to safety and not carry even a trace of static electricity. In the subsequent replication of the assembly line, the oscillation tank should be processed separately in a single room."
"Ah? We still need to build more? How many should we build?"
"Ten!"
After a brief inspection, Song Han flew away silently again.
As soon as Song Han left, a large group of experts immediately swarmed into this huge production workshop.
Watching Song Han board the plane to go abroad using an identity that no one knew whose it was, Wang Wei in the Category III Command Center also let out a long sigh of relief.
"Have you found out yet? Why did he go to Shancheng? I don't believe he just went there to drink and eat skewers so simply!"
Liu Xi handed Wang Wei the final conclusion after several rounds of discussions by the expert group. Wang Wei looked at the report in his hand and asked in confusion,
"PTSD (Post-Traumatic Stress Disorder)? Can aliens also get the psychological diseases that only humans on earth can have?"
"Boss, do you think there's a possibility that he's really a human from the future?"
Wang Wei sneered and said,
"You want me to believe in time travel? I still think the third kind of contact conclusion drawn by the expert group is more reliable."
Liu Xi shrugged and didn't argue but asked,
"Since he's so dangerous, why don't we control him?"
"Do you think I don't want to!"
Wang Wei said helplessly,
"He's still something we can see and touch. What about his enemy?
Until now, we still don't know what that alien is.
If you offend this only person who can fight against the other side, and if that unknown alien causes a tragedy like what happened in Country C in our country, or simply comes to destroy the earth again, what can we use to stop it?
All kinds of weapons except nuclear weapons were used in the war in Huashi, but the other side was still alive and kicking.
Do you think we're stronger than Country C now?"
Wang Wei looked at the plane flying away on the screen and shook his head helplessly,
"Since he doesn't want to have too much contact with us, we can only try our best not to disturb him.
Unless he's willing, who on earth can force him now?"
