After repeatedly analyzing the living debris in the cabin several times, Leo was unable to find any new clues inside, so he transferred the analyzed object to the liquid.

Originally, Leo thought that these liquids were very special and had complex components, so he placed the analysis of liquid components after living debris in the cabin. However, the analysis result surprised him because he found that the composition of these liquids was not complicated and should be a nutrient solution extracted from the body of biological high-energy substances.

In fact, he is also very familiar with this nutrient solution, because every time he participates in a battle, biochemical people who encounter fatal damage on their bodies need to soak in this nutrient solution to repair body damage. The only function of this nutrient solution is to stimulate the body's self-healing or other basic skills, so that creatures using this nutrient solution can improve their physical fitness in a short period of time.

However, he still did not understand what the final effect of this nutrient solution after use is, because the formula of this type of nutrient solution is slightly different, and the effects are completely different. Some nutrient solution repairs soft tissue damage in the body, some nutrient solution repairs bones and nerves damage, and some nutrient solution can even repair damaged brain cells.

The only thing he can be sure of at the moment is that this nutrient solution is specially made for living rooms, because for the human body, the biological energy contained in this nutrient solution is a bit too strong, so thick that it is similar to poison.

He didn't take a lot of nutrient solution from the ship before. After several tests, he almost used up. He went to the metal boat in the Kingdom of Ing. Unfortunately, the nutrient solution in the living cabin on the ship had been consumed. The living cabin, which had lost the nutrient solution, seemed to be in hibernation and appeared as dead wood as a whole.

This discovery also made Leo more certain that the nutrient solution, the ability of living cabins and ships to pass through the gray fog sea has some inevitable connection.

It was just a little strange to Leo, because if these two living compartments were really related to the possibility of ships passing through the gray fog sea, then they should be careful of this secret. After all, this is related to whether the Kingdom of Ing can control maritime hegemony during the period when the gray fog has not dissipated.

But the fact is that the defense on the metal boat is very slack, so loose that it is not only Leo who enters the metal boat like entering his own castle, but even other spies who rushed from all over the Viron continent were like walking around their back gardens and drilling in and out of the metal boat.

Leo only went to the metal ship twice and encountered at least seven people of different forces sneaked into the metal ship to find the secret of the ship passing through the gray fog sea. The entire metal ship was as defenseless as a sieve. Even the guards on the ship needed to infiltrate the forces that infiltrated the ship and triggered conflicts, and then they found that someone had sneaked into the ship.

This relaxed defensive state almost made Leo suspect that the direction he inferred was wrong. The two very abrupt wooden living compartments actually had nothing to do with the ship's passing through the gray fog sea. The ship's ability to pass through the gray fog sea actually came from some extraordinary object worn by the senior management of the ship such as Sean Donald.

However, this idea was quickly overturned by Leo. He still firmly believed that his inference was correct and decided to use the nutrient solution and living debris on his hand to do some experiments.

Although Leo did not have much of this special nutrient solution on hand, only a small test tube, and he did not know what the formula of this nutrient solution was and could not make new nutrient solution, it did not stump him. With a little nutrient solution as the original base material, he had a way to increase the amount of this nutrient solution on hand through the common supplement method used by the Earth Federation Medical Soldier.

Although medical soldiers will try every means to carry enough medical supplies in every battle between the front-line troops of the Earth Federation, often as the battle deepens, the supply line breaks, and the supplement of medical supplies is far lower than the consumption. For this reason, medical soldiers have to use all the materials that can be used to increase the medical supplies at hand.

The supplement method of the Medical Soldier is a supplement method specifically used for various types of nutrient solution. You only need to have a minimum content of nutrient solution reagent on your hand, and this supplement method can increase the nutrient solution reagent by hundreds of times until the basic components of this reagent change due to the combined supplement solution.

On the battlefield, the raw materials used by the medical soldiers to make supplement liquid were countless corpses on the battlefield. Leo naturally did not use this raw material that seemed extremely evil to anyone. He took some useful materials from Sylvia's warehouse, and then made some supplement liquid in his laboratory, successfully replenishing the total amount of special nutrient solution on hand.

Afterwards, he tried to soak the living debris in the cabin on his hand in the nutrient solution and feel every change that the living debris absorbed the nutrient solution.

At the beginning, after the living fragments absorbed a large amount of nutrient solution, there was no change worth paying attention to. However, after the nutrient solution was absorbed to a certain total amount, some sarcoma-like variants began to appear on the surface of the living fragments. Because the living fragments themselves are not large, these sarcoma look more like some meat bumps.

Not long after the formation of the sarcoma, the sarcoma began to dry up and decay, turning into a layer of skin hanging on the living fragments, and then blended into the skin of the living fragments, turning into a wood texture that can almost be messed with, and even the interior is similar to wood.

Just when the sarcoma saccharide completely turned into a woody epidermis, Leo felt that the living fragment was emitting a pheromones outwards. This pheromones were like pheromones produced by some creatures in the universe for the right to reproduction in order to define their territory, and were all emitting some signal outwards.

After discovering this clue, Leo told Sylvia about his discovery. In order to further understand the details of this pheromone, the two of them left the castle and came to a relatively secluded place in the suburbs, and reused the nutrient solution to cultivate living debris.

The scene that Leo saw before appeared in front of the two again. Leo's spiritual network and spiritual vision also recorded every detail of the changes in the living fragments, and also used a universal recorder to capture the biological information waves generated when the pheromone was emitted.

Although Sylvia, who was standing by, did not master every change of this living fragment in all aspects like Leo, she sensed more intuitive content when the living fragments produced pheromones.

"Warning! This is emitting a warning." Sylvia suddenly said without a head or end.

Leo turned his head and looked at Sylvia in confusion.

Sylvia explained in more detail: "Just just now, the blood of the Abyss Demon Dragon on me received a warning, which was directly transmitted to my mind. I could feel that the warning should be published by a very powerful existence, and I also instinctively feel that if there is no need, I should not provoke the source of this warning."

"Pheromone, the warning you received should be from the pheromone made by the living fragment just now." Leo quickly found the reason and said with a smile: "It seems that this should be the reason why the ship can create an illusion of a powerful existence through the gray fog sea, forcing away the monsters hidden in the gray fog."

"It seems a bit risky to do this." Sylvia frowned and said, "If you encounter some more powerful existences, this warning will become a lucky thing."

"Impossible." Leo denied Sylvia's view, looked at the analysis report of the biological information waves generated by pheromones by the universal recorder, and said: "This pheromone is very strange. It creates an illusion that any organism that perceives pheromone will have an illusion that is closer than itself and cannot conflict with it."

The reason why the general recorder gets the results so quickly is that there are just a few similar biological waves in the comparative database of pheromone biowaves on the general recorder. Some organisms in the universe will specially create this illusion to avoid dangers, so that the actual extremely weak body can survive and reproduce in the cruel cosmic environment.

"So that's how it is, it's amazing." Sylvia heard about something like this for the first time, and showed a novel look on her face. Then she looked at Leo with some confusion and said, "You should be more sensitive than me, why don't you feel it at all?"

"Because this pheromone is ineffective for me." Leo responded calmly, but there was still a hint of doubt in his eyes.

In the universe, pheromone biological waves are the most commonly used attack and defense methods for creatures on some planets. They caused a lot of trouble when the Earth Federation opened up colonial planets. A colonial star riot in the early Earth Federation was also because the Biochemical Warriors were affected by the pheromones and produced negative emotions such as violence, destruction, etc., and eventually created a riot that shocked the Earth Federation.

After that riot, the Earth Federation also realized that biochemical people did not completely lose the emotions and desires of normal people as they thought. This kind of emotions and desires are just hidden in the brain and can be stimulated through pheromones and other means.

This discovery is definitely not a good thing for the Earth Federation, because the reason why biochemical people can be promoted and used to replace normal humans to engage in various dangerous tasks and tasks is mainly because biochemical people have no emotions and can faithfully execute any orders, or even let them commit suicide.

But now it is discovered that biochemical people actually have emotions, and this emotion can be stimulated, which makes the senior officials of the Earth Federation wonder whether one day all biochemical people will gain human emotions and launch a military coup to overthrow humanity notice.

Although he became afraid of biochemical people, the Earth Federation did not intend to abandon all biochemical people. Because the Earth Federation has become accustomed to the extremely labor and combat power of biochemical people, biochemical people has become an unforgettable part of the Earth Federation. Therefore, the Earth Federation government can only significantly increase the biochemical people's control devices, and biochemical people can also give up all the organs that can sense pheromones, which completely loses the ability to sense pheromone biowaves.

This is also the reason why Leo is confused. As a biochemical warrior in his previous life, he naturally gave up his ability to perceive pheromone biowaves, but now he has not performed similar operations. In this way, he should be able to sense everything Sylvia sensed at that time.

But in fact, he did not sense any biological wave warning, but only felt the pheromones themselves. This either means that the organ sacking surgery is not as simple as he thought. It is just a surgical procedure, and even the soul is affected, or it is possible that some problems occur in the organs that are now sensible to the pheromones.

Compared to the latter guess, Leo thinks that the former soul-influence hypothesis may be more reliable, because there is not only one organ designed by pheromone, but hundreds of organs, most of which are neuronal cells, and some other organs are also separate sensory organs. It is reasonable to have problems with one or several, but all organs have problems, and this situation is infinitely close to zero.

Just as Leo and Sylvia found the reason why the ships in the Kingdom of Ing were able to pass through the gray fog, a huge, harsh sound suddenly came out of the gray fog on the distant sea.

The huge sound instantly covered the entire Langdall Port and its surroundings. Everyone was frightened by the huge sound and looked at the sea where the sound came.

Immediately afterwards, they saw a fuzzy figure that was so huge that half of its body had penetrated into the clouds in the sky appeared in the gray fog. The figure tried to get out of the gray fog, but was blocked by some force. Finally, it let out an angry roar, and then gradually disappeared into the gray fog.

Although all this happened suddenly, the process was relatively long. And everyone who saw this scene was very clear about the purpose of the huge figure in the gray fog, which also aggravated the inexplicable panic brought by the huge figure.

After all, before this, people in Randall knew that there were some monsters in the gray fog. Those who rashly entered the gray fog would become food for those monsters. However, no matter how terrifying the monsters were, most people almost thought that those monsters had no wisdom and were more like wild beasts.

But now they knew that the monsters in the gray fog were not only as majestic as gods, but also had normal wisdom. What made them even more frightened was that the monsters in the gray fog seemed to intend to come out of the gray fog, which was definitely bad news.

"Is it because of us?" On the hill outside the suburbs near Black Castle, Sylvia couldn't help asking Leo as he watched the huge figure gradually disappear into the grey fog.
