The organ used by the Snow Slime to move in the snow at high speed is only one when used by the Snow Slime itself, and it runs through the entire body of the slime. Although the slime originally did not have the concept of head and tail, after having this organ, the snow slime subconsciously made the suction mouth become the head and the jet port became the tail, so as to maximize this ability.

When this organ was obtained by Shi Leiyin, firstly, this was the ability to devour and fuse, and secondly, Shi Leiyin had the energy and physique far beyond that of the second-order slime, so Shi Leiyin could place this organ in any part of the body at will, and it could be placed in more than one.

This inhalation and ejection organ immediately reminded Shi Leiyin of how the jet engine on the plane works, so while thinking about the way to strengthen it, the first thing that came to mind was to hang symmetrically like the engine on the wing. However, due to the fact that Shi Leiyin's default body is hemispherical and does not have a part like wings to hang the jet organs, in desperation, Shi Leiyin can only appear these two organs directly on both sides of his body, so that two cylinders appear next to his round body. But then the problem arises, Shi Leiyin, who is accustomed to a round body, can barely adapt to the redundancy brought by these two jet organs when moving normally, but when carrying out jet high-speed movement, he can't control the balance and direction well at all, and because of the use of two jet organs, the memory brought by the snow slime core basically has no reference value, so Shi Leiyin hit the ice wall under the cliff very miserably.

Having learned a lesson, Shi Leiyin had no choice but to give up his idea of a twin-engine, and honestly follow the memory of the Snow Slime to use the single-jet method. Moving the jet organ back to the central axis of his body, Shi Lei Yin carried out various realizations on the snow according to the memories and experiences devoured, carefully experiencing the feeling of the jet organ when it was running, and at the same time trying to transform the memories absorbed by the snow slime into his own ability.

The problem of the disconnection between Shi Leiyin's body instinct and Shi Leiyin's consciousness has always been a problem that Shi Leiyin can't solve. But the existence of the same problem makes Shi Leiyin's body adapt to the ability before his consciousness when he gains additional abilities, which he already knew when Shi Leiyin first obtained Harpy's ability, and he has not yet figured out the operation structure of Harpy's cannon, but he can already use the wind cannon to attack. And now that Shrayin is able to use the memories from the Snow Slime to use the jet organs, but cannot use the dual jet organs autonomously, it is also a manifestation of the disconnection between the body's instinct and consciousness. Of course, it is difficult to predict whether this disjointed situation will be good or bad for Shi Leiyin, and Shi Leiyin has never thought of solving it completely, after all, even when he was a human being, Shi Leiyin never thought of figuring out how the organs in his body worked.

After an hour on the ice, Shi Leiyin had a general understanding of how to use the jet organs, and also found that if he increased his output, he could still use this ability to run up on the ice surface like a vertical cliff. It's just that Shi Leiyin hasn't strengthened this organ yet, so he can only move up less than twenty meters, and there is no way to completely climb to the top of the cliff.

In the process of continuous acceleration and deceleration, Shi Leiyin also confirmed that the speed of this ejection organ is based on the ejected gas, and the ice and snow mixture is more like a condensate. In addition to the function of inhaling air and ice and snow, the front swallowing port also has the purpose of controlling the direction of travel. The air, snow and ice that are inhaled into the organs will accelerate within the organs and then shoot out at high speed from the rear of the jet, creating the momentum that propels the body forward. In terms of basic principle, it is really not much different from a jet engine, except that the process of accelerating the gas is not through guò turbocharging, but incomprehensibly bio-supercharging. Shi Leiyin deliberately paid attention to the process of the gas passing through the guò organs, and found that when the three parts of the gas passed through the guò, the gas accelerated and pressurized, and at the same time, the organs consumed the body's energy and there was a heat phenomenon that was enough to quickly dissolve the ice and snow. It's just that the structure and shape of the organs of these three parts are different, and they only shrink and expand rapidly when they work, so that Shi Leiyin, who does not have enough biological knowledge, is completely unable to understand and explain the reason for the pressurization effect, and the only thing that can be confirmed is that when the body strengthens and increases the energy of those parts, it can affect the speed and flow of the air jet, greatly increasing the thrust generated by the jet organs.

Without the slightest hesitation, Shi Leiyin strengthened the composition of the entire organ, originally in order to ensure that the organ can work completely normally, Shi Leiyin perfectly reproduces the shape and strength of this organ in the body of the Snow Slime, which is why Shi Leiyin uses it, the speed will be reduced. After confirming that the strength of the organ can affect the speed, Shi Leiyin directly strengthened the strength of this organ to a few points stronger than the body itself that he usually uses, and focused on increasing the compression and heat resistance of the three parts that are biopressurized - even if he doesn't know how it works, Shi Leiyin at least knows that those three parts are the most important.

After adjusting the output, the jet organ greatly increased Shi Leiyin's movement speed on the snow, and even in the case of maximum output, Shi Leiyin obviously felt that he had basically left the ground, which also meant that the limitations of the snow were no longer self-solving after increasing the output. With the lesson of hitting the wall in the previous time, Shi Leiyin spent nearly an hour more to adapt himself to the maximum speed of 100 meters per second after the enhancement, and then according to his aerodynamic knowledge in his previous life, he slightly changed the aerodynamic form of his body, turning into an elliptical shape similar to the front large and small rear of the wing crosssection.

As Shi Leiyin expected, with a strong thrust and an appearance that could provide lift from the air, Shi Leiyin flew smoothly without spreading his wings. Although the flight attitude in the air is not stable, it is actually in the form of a slime and performs a braking flight in the air. Prior to this, Shrayin had also flown before, but either by using unpowered gliding, or by simply transforming into a harpy form and flying with wings and magic. The former can only fall from top to bottom, and the latter's transformation consumes a huge amount of money, and it is indeed the first time that it can fly up and down in this way, and the consumption is far less than that of the transformation.

Shi Leiyin had no intention of going back to sleep, and in high spirits, he directly chose to continue to grasp his new abilities. Slowly stabilize your flight attitude, and adjust your flight speed and steering speed within a limited range. From the control of energy, Shi Leiyin can confirm that the current flight method, even if it uses the maximum speed that cannot be turned, the consumption is far less than the consumption of transforming into a Harpy or Lemut spider, not even a tenth, but the speed is much faster.

The only drawback is that there is no way to replenish ice and snow in the air to cool the jet organs, and relying on Shi Leiyin's own cooling capacity can only support a maximum of half an hour of flight. Of course, if Thunder is willing to spend mana to create and use the Ice Elemental ability that he has acquired for a short time, he can maintain his maximum flight speed until his mana is exhausted.

It took another two hours for Shi Leiyin to finally control his flight posture in the air, and he could steadily accelerate in a certain direction or make an emergency turn. However, on the contrary, his appearance in the air is close to the appearance of a missile, intentionally or unintentionally. Although the body still maintains a streamlined shape that is large in the front and small in the back, there are four more cross-shaped tail fins behind it. Through these four tail fins, Shi Leiyin can stabilize his flight altitude at high speed, and at the same time, he can also quickly carry out nearly 90 degrees of steering in the four directions of up, down, left and right.
