"100 reward points for one person, not much, it should be regarded as the main god reimbursing us for a day's travel expenses." Zhang Haolin finished his work and rejoined Wen Yu, who was hiding not far away: "Next, I will find a laboratory for studying liquid metals, and I hope that the bankruptcy of Cybertron will not affect this laboratory." ”

"It's so boring, you take the book out and I'll read it for a while."

"When I figure it out and go out with you at night, you can think about where you want to go, and if you can't think of it, it's also a good option to go directly to open a room and discuss life."

"Hmph—"

Liquid metal, unlike bionic computers, is at best an excellent new material, not a major discovery that is so mysterious that it needs to be kept secret from the public, even without hacking software, just a search in a search engine can easily find a lot of relevant literature and laboratory information.

……

What makes people speechless is that because it is not a confidential thing, Zhang Haolin has run into trouble - there are too many laboratories to study liquid metal, and some are trying to study and improve this material; Some people want to find out the principle and develop better peers, and more are exploring the practical application value of liquid metal in production and life...... The massive number of search results dazzles the reincarnators.

Zhang Haolin was defeated, and honestly opened the auxiliary software provided by the main god, and conducted an intelligent search with the keywords "solidification", "liquid metal" and "laboratory", and finally narrowed down the search results.

The next step is to narrow down the target again, Cybertron's scientific department is under the covert control of John Connor, a magnetic particle robot sent by Skynet from the future. It will certainly be the first institution to start working on the solidification of liquid metal, and with the large amount of relevant information brought back by the T-3000, the relevant laboratories operated by it should be the most advanced...... So. Add the keyword "Cybertron" and it should be more precise.

After half an hour of tossing, Zhang Haolin finally chose the target - Cybertron funded the next university's affiliated laboratory, which had been conducting experiments on solidifying liquid metal, and was progressing well. Although the project has been discontinued after the bankruptcy of the company. But the people working on the project are definitely still ......

By the time the list of laboratory directors and core experimenters was clarified, it was already dark, and it took two days anyway. Zhang Haolin decisively put away the computer and pulled Wen Yu to see the night view of San Francisco.

――

A room full of lab equipment, a doctor-like white coat, hoods, goggles, rubber gloves, suit pants and leather shoes sticking out of the hem of the coat...... It took Zhang Haolin a little time to find this laboratory, but it didn't take any effort to find someone. The project to solidify the liquid metal was halted because of a rupture in the source of funding. However, the laboratory is not affiliated with Cybertron. It was still running as usual, and there were not even any personnel changes here within a month, and when it was time to go to work, all the technicians who should have come arrived in the laboratory one by one and began to tackle another scientific research project.

Fortunately, I didn't force my way over to find someone after dark last night, and I slept again this morning......

"Hello Doctor, we are...... Well, expatriates from the Light God Corporation. Come and visit the lab, if there is a suitable project. I can invest in supporting you. After being tossed overnight, Wen Yu's legs were still a little sore, fragmented, and clumsy in a panic, anyway, under the effect of tenfold crushing mental ability, the other party would believe what she said: "We want to see the progress of solidifying liquid metal in your laboratory, please ...... Show us how. ”

"Solidifying liquid metal?" The person in charge of the laboratory repeated with some surprise: "Ah...... It's a pity, that project has already progressed, but Cybertron has been hit by a terrorist attack, and such a big company is bankrupt when it says it is bankrupt...... If you want to see it, you'll have to wait a minute, and I'll have a couple of students take the devices back out. ”

"Okay, we're not in a hurry." Zhang Haolin nodded very politely, stood aside, watched the students who had helped the doctor go in and out, and soon moved in a large pile of equipment that looked very simple, assembled and assembled, and became a tall and strange complex instrument.

……

"If I don't want to fully understand it, I can explain to you in the simplest way possible how it works to solidify liquid metal - the existence of such a thing as liquid metal is to use the interaction between the constituent components to weaken the bond between the microstructures, so as to maintain a liquid state at room temperature." The slightly hypnotized laboratory head explained to Zhang Haolin while watching his subordinates assemble the instrument: "Therefore, it is very simple to let it solidify: electric field, magnetic field, laser ...... Whatever you do, re-strengthen the binding energy in the microstructure, and it can be solidified smoothly. ”

"Well, it sounds simple, but what about the difficulty of the experiment?"

"The difficulty is that at the beginning, we can make liquid metal through mutual inhibition and binding between components, and if we force it to solidify by violent means, it will produce delamination - this instrument uses the electric field curing method, which cures the liquid metal and then removes the electric field, so that about one-third of the liquid metal can no longer return to its original state, and it becomes a mixture of liquid metal and solid particles of each component......

"You mean, curing will cause some of the liquid metal to deteriorate?"

"That's right, Mr. John Connor is also a science student, and Mr. John Connor, who used to come to check on our lab, is also a science student, and he is most comfortable with this kind of investor, not only will he not interfere with the experiment like a layman, but sometimes he can give constructive suggestions." The doctor said with some emotion, "Our original idea was to stop the deterioration of the curing process, but Mr. John Connor gave us a new idea-"

"What?" Familiar names suddenly appeared in the conversation, and Zhang Haolin's voice was raised a lot: "John Connor gave you a new idea?" ”

"yes, what's wrong. It's a pity that such an excellent character is said to have died in a terrorist attack, alas......"

John Connor returned to this era after being controlled by the future Skynet, and the new ideas he gave were the practical solutions adopted by the future T-1000 nine times out of ten. Unexpectedly, the mechanical reincarnation left himself with excellent liquid metal. Skynet sent myself a door-to-door use method again! Zhang Haolin was so excited that he wanted to laugh out loud at the moment, and he suppressed his emotions, and he asked unhurriedly: "Hmm." What a new idea? ”

"In order to keep the liquid metal unchanged in the process of curing at room temperature, we already had some theoretical ideas, but we have not been able to make any progress in experiments, this idea requires a lot of energy to forcibly inhibit delamination, but the energy that inhibits delamination will conflict with the energy that promotes curing, resulting in an exponential increase in the energy required for this process...... The amount of energy required for liquid metal to solidify with zero deterioration is astronomical. The doctor continued to explain in a slightly admiring tone, "And Mr. Connor's idea is not to prevent deterioration. Rather, at the moment of re-liquefaction after curing, the energy field is used to instantly eliminate the delamination phenomenon......"

It took a while to understand the information, and Zhang Haolin understood a little: "I understand." This means that solidifying the liquid metal causes the liquid metal to deteriorate, but we don't prevent the deterioration, but reverse the deterioration after re-liquefaction, just like a battery. The chemical composition of the interior is not the same when fully charged and when it is empty. Is the material composition of liquid metal different in the solidified and liquefied states? ”

"Yes, every decuring is actually equivalent to reproducing liquid metal from the deteriorated ingredients." The doctor nodded affirmatively: "Although this solution is troublesome, it is the most energy-saving and practical method, as long as the proportion of deterioration is reduced by improving the liquid metal composition, and finally the solid-liquid state can be easily switched at will." ”

"Well, I see." Zhang Haolin nodded, the instrument had been installed. Just wait for the trial. One of the experimenters had already retrieved a jar of liquid metal, but a few liters each. But it was so heavy that it needed to be held to move, and several people came to the side of the instrument, watched the experimenter use an external computer to set the parameters and start the power supply.

"Let's see, let's use a little bit to demonstrate." The doctor took out some liquid metal and placed it in the groove of the instrument, and with a slight humming sound, the small pool of liquid metal was slowly converted into a solid state in the electric field. In Zhang Haolin's magnetic scanning, the magnetic field in this liquid was slightly enhanced, the structure changed rapidly, and the position structure between molecules and atoms quickly condensed and fixed, and after a while, it turned into a solid.

"You can touch it, but it's better to wear gloves." The doctor takes the tray out and pulls out the piece on top.

"It's okay, it's not poisonous anyway." Zhang Haolin received it in his hand, indeed, the puddle that was like mercury before has now become a hard piece, except for the slight heat, it is similar to an ordinary iron piece.

With a single force, the "iron sheet" was slightly bent and broke like a piece of shortbread.

"How can it be so brittle, shouldn't the malleability of metal be very good?"

"After taking out the electric field, the part that has not deteriorated will quickly begin to liquefy, and the part that has deteriorated is not a whole, but a layer." "It's not that the solidified liquid metal is broken, it's that it's that the different compositions are separated by different degrees of strain, and you can wait until it's completely melted to see how it's different from the unspoiled liquid metal," the doctor said. ”

Some of the warm solid tablets gradually became cold and soft, and after more than ten seconds, they completely turned into a puddle, and used the ability to control the liquid not to leak out of the fingers, Zhang Haolin pinched a little bit with his fingers and rubbed it hard.

It feels like sand has been added to the water, and the texture is extremely poor because it is mixed with an indescribable roughness to the touch, which should be smooth.

"Those fine particles are the raw materials that have been precipitated by metamorphism, and now this large pool is put back into the instrument and reversed, and the liquid metal can be obtained again."

"Hmm." Gently pouring the things in the palm of his hand back into the tray, relying on his ability to clean up some of the remaining injuries, Zhang Haolin asked with some doubts: "So, isn't the experiment completely completed, and the liquid metal can be switched freely between solid and liquid states, why do you still say that the experiment is only a little progressive?" ”

"There are two other problems, although small, but difficult to deal with - it is too slow to restore the deteriorated liquid metal to the required components, and it is not possible to achieve 100% reversal for the time being...... "A metal that can freely change its solid and liquid state at room temperature, especially in electrical machinery...... For example, the changes that can be caused by bearings, detectors, joints, and other fields are amazing, and you can know if you think about it on your knees - but if it takes several or even dozens of hours to transform between different states, and each transformation causes loss, then it has no practical or commercial value at all. ”

"I see, if it's converted too slowly, and the loss is greater than the normal frictional loss between solid elements, it really won't be useful." Zhang Haolin wants to master the ability to solidify liquid metal, and he wants to change swords, plate armor and other parts for attack and defense at any time during the battle, but if the transformation takes a few to disappear, it will also consume the material...... That's still a hair.

"We still need a lot of money to improve the liquid metal and electric field control equipment, and if it succeeds, even if it only collects royalties, we can lie down and enjoy it for a lifetime, you see...... Interested in making some investments? ”

"Well, let me observe the process of re-converting the metamorphic material into liquid metal."

"No problem."

In Zhang Haolin's senses, the impurity particles in the liquid metal slowly dissolved at an imperceptible speed under the action of the special electric field, and remixed together to become liquid metal.

This process is very slow, and Zhang Haolin also patiently senses the phase transition of the liquid metal, and at the same time thinks in his mind, how to control the magnetic field to perform equivalent operations?

Wen Yu was bored on the side, sitting on a rotating chair next to him playing the trick of turning in circles, curiously looking at everything in the laboratory, but he didn't know that he had also become a scenery in the laboratory, and several young experimenters stared intently at the pretty visitors, and even forgot to do their work.

There are still twenty hours before they leave this world, and they can carry out research unhurriedly, but a little trouble has come to them-Wen Yu was looking at an experimental record on the table, and suddenly sensed something, stood up and walked to the window, his fingers opened the shutter blades and looked downstairs, and then became nervous: "Haolin, there are policemen downstairs!" ”

"Huh?" The man didn't react immediately, and only remembered after a while: their identity in this world is more embarrassing, and they are being hunted down!

"You can find a way to delay me for a while, I'll figure out the curing and decuring principles and I'm leaving!"

"Okay, you hurry up." Wen Yu reluctantly left the window and walked towards the door: "How can I drag it......"

Zhang Haolin reached out and picked up the tray in the instrument, poured out the first generation of liquid metal in it, took out about a spoonful of HJ-Y alloy from the ring and put it into the container: "Use this directly for testing, I'm in a hurry!" ”

"Uh-huh-" The doctor was responsive to potential funders, and although he couldn't see anything unusual about what the other party had come up with, he obediently began to set the parameters of the instrument.
