It is no exaggeration to say that Andrew's Lab is one of the strongest laboratories in the five star fields. Although Ronnie has been invaded by a large-scale ironclad cockroach, Andrew's laboratory is still impregnable, but this is not a problem for a refiner, especially when there is no one to guard it.

Zhou Sen melted a hole, and then swaggered in.

Zhou Sen knew Andrew's lab well, and he cut off all surveillance and automation weapons first.

After entering the laboratory, Zhou Sen drove all the way to the warehouse, and he felt fortunate that the laboratory not only had no problems with the energy supply, but also the password authority he had was also valid. Of course, Zhou Sen doesn't care if it's effective or not, as long as he has the ability to smelt gold and iron, no security system can stop him, but if the password permission is valid, he will be more relaxed.

When Zhou Sen entered the warehouse and looked at the dazzling array of experimental materials on the shelves, he was in a daze.

Zhou Sen spent his childhood and adolescence here.

The sleeping memories seem to be suddenly clear, familiar faces, familiar people, familiar machines, and bottles of familiar reagents......

……

Zhou Sen stood at the door of the warehouse for five minutes before he woke up from his remembrance, shook his head, got rid of the distractions in his brain, and began to collect the materials he needed with a clear goal.

Zhou Sen has prepared a list long ago.

When he came to Andrew's lab, Zhou Sen cleared out most of the materials in order to make room for the space button, leaving only gold, and gold took up the least space.

Metallic materials.

Inorganic non-metallic materials.

Polymer materials.

Composites......

In the Middle Ages of the Old Earth, humans did not make much progress in separating the elements, but alchemy emerged during this period.

In the early days, the alchemists used very simple devices, such as stills, milk bowls, etc., and those simple devices were the origin of chemical instruments.

The alchemists were the pioneers of modern chemical experimentation, from the search for the elixir of immortality to all sorts of magical and strange experiments, and they were all looking for the so-called "philosopher's stone", a substance that could turn ordinary metals into gold, and the early alchemists were convinced of this.

To this day, scientists don't know exactly what that dreamlike thing is, it may be more than one substance, it could be a "stone", some historians speculate that it is mercury sulfide, but no one has been able to confirm this hypothesis.

Of course, in addition to the impracticalities, the alchemists did do many important chemical experiments, although these things were not what they wanted to do in the first place, but they succeeded in extracting all kinds of metals from various ores, and most importantly, they created many acids, which became the building blocks of industrial chemistry in later generations.

The early alchemists gathered the knowledge gained from the experiments and tried to systematize them, believing that the four elements of fire, earth, water, and air were interrelated and were the technical substances that made up nature, and they wanted to use these four elements to establish a logical theory.

Although some of the theories of alchemists are no different from fantasy, in some ways it can be called the prototype of the modern periodic table......

Zhou Sen's attempt to combine refining with science was not a whim, but a deliberate one.

Zhou Sen thought that the ability he possessed was actually the ability possessed by the alchemists of the ancient earth era, so he consulted a large number of historical records of alchemists, and he found that arsenic, antimony, and bismuth, the three elements belonging to the same family, were discovered by alchemists, and nothing was found for a long time since these three elements were discovered.

In the seventeenth century, humans have discovered thirteen elements, but there is no record of the age of their discovery and the name of the person who discovered them, which is obviously not in line with scientific experiments, and the only explanation is that alchemists did it.

Zhou Sen guessed that the alchemists at that time were just to complete their goals, and did not make a system, resulting in the alchemists being unable to pass on, and in the era of the Big Bang of ancient earth science and technology, human scientists have realized these problems and began to sort out the modern periodic table, and made great contributions to the development of science and technology, laying a solid foundation for human science and technology.

Ancient alchemists are actually similar to ancient Chinese medicine, they do not have a perfect theoretical system, and they cannot be copied, completely relying on the personal experience of doctors to hang the pot came out, until the rise of human science, some experience began to be replicated and promoted on a large scale, and it was applied on a large scale under the impetus of the power of science and technology.

Strictly speaking, refiners and alchemists are the predecessors of human technology, and now, it is completely feasible to combine human technology and push it back to ancient refining and alchemy, and it is relatively easier, after all, the development of human science and technology to this day, the application of materials science has reached its peak, and there is no need to explore in the dark like ancient refiners and alchemists.

Whether it is refining or alchemy, its essence is the combined application of materials science and chemistry.

In the next week after entering Andrew's laboratory warehouse, Zhou Sen used the method of refining weapons to refine some powerful weapons, including the most primitive nuclear bomb and hydrogen bomb of mankind.

For Zhou Sen, it is very easy to use the knowledge he has to create a powerful weapon, even if it is a weapon to destroy a planet, it is not difficult, and the most difficult thing is to make the weapon miniaturized and easy to carry.

The most important thing is not to hurt yourself when using weapons, this is a technical job.

Zhou Sen actually knew very little about refining weapons, and the only way he could do it was to use his ability to refine weapons in science and technology.

Now, the problem that Zhou Sen needs to solve is to create a weapon that releases huge energy in a very small range, that is, to limit the killing space of this weapon when it is used, so as to avoid affecting innocent people and himself, which is similar to the directed energy weapon developed by human beings, also known as beam energy weapon, which is a weapon that uses a certain way to produce extremely high energy density on the surface of the object, so as to lay down the damage of personnel and electronic equipment, weapons and other handbags, and produce powerful lethality.

Because of the different carriers, there are many types of directed energy weapons, including laser weapons, microwave weapons, particle beam weapons, sound wave weapons, radio frequency weapons, and so on. It uses the energy of lasers, microwaves, particle beams, sound waves, etc., to produce comprehensive effects such as high temperature, ionization, radiation, and sound waves, thereby causing damage to the target.

Zhou Sen stayed in Andrew's laboratory to do experiments mainly because there were not only all kinds of experimental materials, but also a variety of test equipment, which were not expensive and could not be bought with money.

As long as there is equipment, it is easy for Zhou Sen to create directional weapons, but the problem is that he has to make these weapons by refining weapons, because, only in this way, he will be able to make a large number of weapons for himself anytime and anywhere in the future to compete with the gods, instead of sitting back and waiting for death......
