The two things that Leach had placed were a failed alchemy product.

Although alchemists have a certain talent for magic, they are obsessed with alchemy, but they do not have much time to strengthen themselves.

In order to ensure their own safety and that the results of alchemy will not be violently robbed, alchemists generally have two options.

One way is to hire thugs with a lot of money, but this choice has a certain risk, after all, people are separated from their stomachs, so this method is generally only chosen by those alchemists who have a backstage, except for the first method, the other method is to rely on the alchemists themselves to make trap beasts and alchemy creatures.

However, although the trap beasts and alchemy creatures are not as loyal and fearless as humans, they also have the great disadvantage of being difficult to carry around. Because of this, trap beasts and alchemist creatures are generally used by alchemists for the defense of their laboratories, and as for what materials need to be collected in the wild, they either have to pay a large bounty or hire someone.

In order to prevent this embarrassment from persisting, some alchemists wanted to invent a portable trap beast or alchemy creature.

In the beginning, the alchemists tried to simplify and shrink the various parts of the Trap Beast as much as possible, but although they succeeded in creating a very small Trap Beast, due to the reduction of many materials, the new miniature Trap Beast was very different from what was expected in terms of agility, defense and attack power, and completely lost the meaning of the existence of the Trap Beast, and became a toy-like existence.

After the first failure, and realizing that it would be impossible to make a breakthrough in the field of Trap Beasts unless a new metal smelting technology appeared, the alchemists set their sights on alchemical creatures again.

Since the demonic beast that is used as the prototype will be damaged to the brain during the refining process, the intelligence level of the alchemy creatures is not high, and they cannot receive complex instructions at all, which is why the alchemy creatures will only stay in one place and ignore any intruders outside their territory.

In order to make alchemy creatures easy to carry, alchemists took a detour at first, wanting to choose those smaller magical beasts as materials.

Any experiment has to be gradually deepened from simple to difficult, so at first, the alchemists only experimented with low-level magical beasts, but what they didn't expect was that the first step of the experiment was extremely difficult.

The low-level demonic beast couldn't bear the pain of the refining process at all, and died before it was over.

Helplessly, the alchemists had no choice but to hit the idea on the mid-level demonic beasts.

However, the problem comes again, the vast majority of the size of the demonic beasts is directly proportional to their strength, and the few abnormal ones are either scarce and difficult to catch, or they are particularly difficult to deal with, and the experimental materials have not been found, let alone the success of the experiment.

I have to say that to be an outstanding alchemist, in addition to love and talent, you also need to have an unbridled imagination.

Unable to find smaller beasts, alchemists began to think about how to make the larger beasts smaller.

Alchemists, immersed in the passion for developing new realms, do not even think that their new subject is no longer within the realm of human beings.

You must know that after tens of millions of years of evolution, a species has basically been stereotyped, and it is impossible to change the form formed by tens of millions of years in just a few decades or even a few years, unless it is a god.

As a result, naturally, after torturing countless demonic beasts to death, the alchemists had to admit that this matter was not within their power.

At this point, some of the alchemists who had been full of passion at the beginning finally came to their senses and withdrew from the study, but there were still a considerable number of alchemists who were happy to overcome the difficulties.

After countless failures, the alchemists who still insisted on it came up with a new idea: why did the alchemy creature have to be based on the monster, why couldn't they create a new alchemical creature that had never existed in this world?

As mentioned earlier, alchemists have a certain talent for magic and a certain understanding of magic, and what inspires them is the high-level magic of the water system, summoning the water element.

The water element, as the name suggests, is a magical creature composed of the magic elements of the water system, without life, and will only act according to the will of the summoner, and the most important thing is that no matter how high or low the spiritual power is, the summoned water element is about the same size as a human being, and the difference is only the level of combat effectiveness.

From the above points, it can be said that except for the water element, which is not an alchemical creature but is summoned by magic, the rest fully meet the requirements of alchemists.

From this point of view, the alchemists began to invite mages from the water system to join the ranks of research, and when the research process hit a bottleneck, they invited mages from other departments to participate.

Originally, according to the idea of the alchemists, they wanted to develop an alchemical creature similar to the water element, but the water is invisible, and if it is not driven by considerable spiritual power, it cannot be fixed into a certain shape at all, and this alone rejects all alchemists, let alone want to make a "bodyguard".

Water doesn't work, so look for things that have a fixed form. Then they thought of trees.

This was inspired by the fact that in ancient times, the elves possessed the War Treants, a combat weapon similar to alchemical creatures.

Unfortunately, it backfired, although the trees were tangible, they were fragile in their own texture, and no matter how they were strengthened, they could not meet the minimum requirements of the alchemists, and those who met the requirements became a problem, and in the end, they were not able to do so.

After ruling out an option again, it occurred to some alchemists that they seemed to be able to use the ubiquitous rocks as raw materials.

However, in this way, the portability of the new alchemy creature has become an issue again.

Then some alchemists proposed that they didn't need to make a finished product like a trap beast, they only needed to make a core, and when needed, embed the core into the rock, and the "bodyguard" they needed would appear, and they didn't have to carry a big man around at all.

The new proposal was accepted by the vast majority of alchemists, and the research was allowed to proceed once again.

In order to achieve the desired effect, alchemists first need a power source, and since they are only making a core, it is best that the power source itself can be made into a core.

Then, the core of the earth-based demonic beast became the best choice.

After countless trials and improvements, the rock golem was born.
