It took a day for Shi Leiyin to quickly switch between human and spherical shapes. This is actually very easy, after completing the human form, Shi Leiyin has a fixed memory of the composition of the body. This ability to immobilize memories was noticed by Shi Leiyin after conducting flight training. Originally, Shi Leiyin has always had the situation that the shape of his body often remains in the spherical shape after his initial compression of the body, and in Shi Leiyin's opinion, it is because he subconsciously thinks that the slime should be this spherical shape. After changing his physical state to a certain extent due to the need for flight training, Shi Leiyin realized that his spherical body seemed to be memorized by his body. With just one thought, the body can change from any form back to spherical shape.

However, Shi Leiyin didn't take this situation to heart at that time, and it wasn't until after completing the humanoid state that Shi Leiyin considered the complexity of the humanoid form and the time it took to establish the humanoid form, and then he thought of whether he could let his body remember the humanoid form like a memory ball shape.

The experiment was very successful, under the deliberate guidance of Shi Leiyin, the body naturally remembered the form of the humanoid, and the memory of the spherical form was not forgotten, now only one thought of Shi Leiyin, you can switch between the two forms of the human and the spherical at any time, but in the process of changing from the spherical type to the human form, a very small part of the energy will be consumed, and the change from the human type back to the spherical type is not required.

The only thing that became a problem was that Shi Leiyin forgot to adjust his head when he memorized the humanoid - because the head has no bones and muscles, Shi Leiyin did not refine the head that adjusted the humanoid state, so the head of the humanoid state that was memorized by the body was a slime head similar to his own spherical body.

For this reason, Shi Leiyin could only specially make a permanent bone mask and wear it on his face when he changed into a human form, avoiding the trouble of refining and adjusting his face. However, this bone mask is not very well received, as it is fully covered and has only two skull-like eye holes. Nicknamed by Zilde, who had seen Danatos' distress, Danatos's brainlessness - slimes were originally brainless, Zilde said.

After having the mask, Shi Leiyin also considered the issue of clothing after transforming into an adult. Although there are no gender characteristics that need to be concealed in the human appearance, it is always not okay to run naked or anything, especially when there are three boys and girls around whom, regardless of their actual age, look absolutely underage on the outside.

The hooded cloak was an item that had been left with him before, and in order to avoid accidentally breaking it, Shi Leiyin bought a few extra sets in addition to the one he and Zilde were wearing, as a backup in case of emergency. And these sets of useless cloaks have become the material for Shi Leiyin's costumes.

It's not that Shi Leiyin hasn't considered the appearance of directly using the slime body to form a costume, but the slime body is not a universal machine, and the energy consumed by using the slime's body to simulate an ingredient like cloth and silk actually exceeds the need to form metal armor. At the same time, if you don't concentrate on your clothes, your body will soon assimilate the clothes from the outside and turn them into skin. The transformation of the metal armor, although it can avoid the previous problems, will make the body very heavy - it needs to absorb a large amount of additional metal components to build a metal armor of sufficient size, and Shi Leiyin cannot wear bikini armor.

Although it is a hassle and a waste of energy to construct clothes from one's own body, it does not cost Shi Leiyin too much energy to use the slime trait to fuse and transform the cloth into his stomach. Although Shi Leiyin has not thoroughly studied the operation of the Devouring Fusion ability, he has been able to use some of his abilities to simply modify the objects that have been swallowed into his body - it is not too difficult to sew the cloak into clothes and pants according to his own ideas.

Due to the limited materials and the limited level of tailoring, Shi Leiyin actually made a blouse similar to a long-sleeved shirt for his humanoid body, a pair of trousers, and a pair of cloth shoes with leather shoe style from leftover scraps. 'It's okay to be able to cover your feet, it doesn't matter if you feel comfortable or anything," Shi Leiyin said.

Cover most of your body with clothing, a mask, and a hooded cloak over it. After humanization, even if Shi Leiyin makes some combat actions, he will basically not reveal his identity as a slime, but three days is not enough for him to maintain his human style when fighting.

When fighting with the White Speed Dragons, Shi Lei Yin is still very accustomed to using his slime fighting style - a tentacle may suddenly appear in any position on his body and knock the White Speed Dragon into the air that pounces on him, or suddenly the tentacle turns into the claws of the Lemut Spider and splits the White Speed Dragon trying to contain his tentacles in half. And the body is bent and changed at an angle that violates ergonomics, and can even twist left and right into an S shape to avoid the attack of the White Speed Dragon.

Of course, in addition to the combat strength of the physical body, Shi Leiyin also has a weapon that is specially used in the humanoid form. It was a longsword made of ice. After using the Rushing Flow* Extreme Intent and the Elemental* Fusion, Shi Leiyin actually had some thoughts about making a sword on his own. It's just that the slime uses a sword or something that is really uncoordinated and redundant, after all, the sharpness of the Lemut spider legs that he has changed is far greater than that of ordinary swords. It wasn't until he completed his humanoid form that Shi Leiyin considered the feasibility of using weapons again when he was considering what method to use in his humanoid form, and this was the ice sword.

At first, the sword made of ice was influenced by the Ice Dragon Sky Dance, but after the actual production, Shi Lei Yin found that because the contact time with the Ice Dragon * Sky Dance was too short, let alone simulating the powerful magic of the Nine Dragons Fort, it was impossible to make a magic ice sword that could release ice archery. So Shi Leiyin turned the direction of production to the ice sword itself.

Sharpness and tenacity are one of the most important indicators of a sword, and there is no big problem with the sharpness of the sword made of ice, when the blade part of the ice sword is refined and arranged at the level of ice crystal, the ice sword is only one step away from sharpening the iron like mud, at least the ordinary iron sword will only leave a white mark on the trunk of the frozen soil tree, and the ice sword can be cut off without even spending money. However, in terms of toughness, the ice sword is a little far behind, the ice sword made of ordinary ice is very brittle, and it is okay when using the sharpness of the blade to slash, but the spine of the sword is very easy to shatter when it is impacted. Therefore, Shi Leiyin chose to use special ice cubes to make an iron sword. The ice cube that previously constituted the Ice Lotus where the Ice Dragon * Sky Dance was located was Shi Leiyin's first choice, but after losing the magic support of the Ice Dragon * Sky Dance, the toughness of this ice has decreased, although it is still much tougher than ordinary ice, but compared to the metal used by ordinary sword makers, the toughness is much worse. As a result, Shi Leiyin chose to use the ice crystals reconstituted in his body to make an ice sword.

The ice element crystals absorbed by Shi Leiyin in the ice lotus are very tough, so in addition to the ice element itself being absorbed by Shi Leiyin, the composition of this ice element crystals has also been memorized by Shi Leiyin's body. When reconstituted in Shi Leiyin's body, due to Shi Leiyin's deliberate control of the consumption of magic and energy, the tenacity of the ice elemental crystals decreased slightly due to the decrease in density, but Shi Leiyin used another method to compensate for this - the structure of Shi Leiyin's jaw was applied to the structure of the ice crystals forming the ice sword.

The bone structure of the jaw of the Crashing Dragon is originally characterized by lightness and hardness, and the bone structure has a special spatial structure like a honeycomb, and the jaw is much lighter than it looks when it is hard. And Shi Leiyin used a similar structure to form the sword body part when he was constructing the ice sword.

In the end, the ice sword made by Shi Leiyin was not only sharp and hard, but also very light, which was very suitable for a layman like Shi Leiyin who made a sword.
