Chapter 1638: Training on Odor Tolerance in a Biogas Tank

Qin Yuan quietly observed the actions of the group of young people behind the hillside. Based on their actions, he could see that Duan Jinglin and Bai Chenyang were indeed analyzing the tiny traces he left behind, which was exactly the effect he wanted.

A few minutes later, Bai Chenyang and a few others quietly approached the other side of the hillside, wanting to surround Qin Yuan. Seeing their caution, Qin Yuan decided to give them a head start.

He slid down from one end of the hillside and used the terrain to get behind them. He approached quietly and stopped behind Duan Jinglin silently, with his fingers gently resting on his shoulders.

"Your actions are good, but not enough." Qin Yuan whispered. Duan Jinglin turned around suddenly, but Qin Yuan had already jumped up and escaped from their encirclement, leaving only a series of complex footprints and a trace of wind.

Duan Jinglin was a little annoyed by Qin Yuan's trick again, but he knew that this kind of training was to improve their reaction ability and tactical level. He calmed down and led the team members to replan the search route.

Qin Yuan went around to the other side and used the uneven terrain to constantly change his position, making it impossible for Yue Ming and others to predict his movements. He skillfully used the slopes, tall grass and shrubs to randomly change his hiding place, and every step was carefully calculated.

In the process of constantly changing positions, Qin Yuan always kept an eye on Yue Ming and others. He considered everyone's strengths and weaknesses and paid close attention to their performance during the search.

With the advantages of physical fitness and familiarity with the terrain, he kept trying to guide the group of young people into the trap he set.

In the jungle on the edge of the cliff, a shadow flashed in the tall grass. This was a trace of Qin Yuan's figure deliberately exposed. Seeing this scene, Duan Jinglin hurriedly signaled everyone to adjust the direction.

But when they carefully advanced in that direction, Qin Yuan had quietly gone around to another hidden place. He wanted to use these illusions to test their judgment and execution.

A few minutes later, Bai Chenyang identified some clues again, and everyone quickly adjusted the search formation. However, Qin Yuan had already predicted their reaction and calmly chose a route opposite to their expectations, and once again went around from the flank to their rear.

"Stay alert and pay attention to the movements around you!" Duan Jinglin whispered.

Yue Ming and others nervously searched for the movements around them, everyone's nerves were tense, and sweat slid down their cheeks.

Just as they adjusted their formation and advanced in a relatively ideal way, Qin Yuan's figure once again appeared silently on the other side of them.

Qin Yuan used the cover of tall grass and bushes, sometimes lurking, sometimes suddenly appearing, and crossing their line again at a very fast speed. This series of actions further highlighted his agility and accurate predictive ability.

Duan Jinglin and Bai Chenyang tried to save their energy. They knew that the training with Qin Yuan was a protracted battle, but even so, fatigue and pressure caused their team to begin to show subtle flaws.

After Qin Yuan's figure flashed in the grass, Yue Ming and others nervously accelerated the search. They gradually approached the location where Qin Yuan had just appeared, but found that it was just a carefully forged disguise.

A thick mushroom stone was arranged like a human figure. The breeze blew and the grass leaves swayed gently, as if mocking them.

In just a few minutes, Yue Ming and others gradually entered Qin Yuan's sight. They obviously raised their vigilance and were no longer eager to blindly chase, but steadily advanced little by little.

This change made Qin Yuan nod in his heart. Duan Jinglin led the team to advance slowly but firmly. Every step was carefully designed and judged, trying not to give Qin Yuan any opportunity.

Passing through the jungle with complex terrain, Qin Yuan once again cleverly ambushed behind a dense bush. After he initially judged the possible route of the other party, he quickly arranged simple but appropriate traps at several key locations.

The team approached Qin Yuan's possible position cautiously, without noticing the thin line under their feet. With a "pop" sound, a bunch of dry grass was suddenly pulled up, and a small smoke burst out. Yue Ming's pupils shrank, and he immediately commanded the team members to dodge: "There is a trap, be careful!"

The smoke spread, and they dispersed at the fastest speed, bypassing the trap, while Duan Jinglin and Bai Chenyang tacitly assigned tasks in the huge bushes and gradually advanced.

From their pace and movements, it can be seen that more and more vigilance and experience are being formed, but they are still in the trap carefully designed by Qin Yuan.

Their steps are getting more and more careful, but the feeling of fatigue gradually invades everyone's body. Duan Jinglin's tense nerves have not relaxed for a moment. He knows that Qin Yuan is still around them and may appear again at any time.

A piece of grass spread behind the bushes, making it look like a natural extension of vegetation. Duan Jinglin accidentally stepped on it, and suddenly felt empty under his feet and lost his balance instantly.

He reacted quickly, leaning his body sideways, supporting the ground with one hand, barely avoiding the trap, but this momentary mistake exposed his location.

Qin Yuan did not miss this opportunity. He jumped out of the bunker at lightning speed, his feet lightly skimmed over the grass, and approached Duan Jinglin almost silently.

Before Duan Jinglin could stand completely, Qin Yuan's hands had already clasped his shoulders like iron clamps. Then, Qin Yuan pushed him hard, and Duan Jinglin staggered back a few steps and fell into the low-lying area next to him.

After Duan Jinglin fell into the low-lying area, the others immediately reacted and rushed towards Qin Yuan. Qin Yuan seemed to disappear out of thin air and blended into the surrounding environment again.

"Everyone, don't spread out, stay in formation!" Bai Chenyang reminded in a deep voice. He knew that he could not compete with Qin Yuan alone. Only with tacit cooperation could he have any hope of catching Qin Yuan's traces.

Qin Yuan disappeared into the bushes again, and Yue Ming and others became more nervous. They knew Qin Yuan's ability, both tactically and psychologically, and they should not take it lightly.

Although they were fully prepared, Qin Yuan could always catch them off guard in the most unexpected place.

Duan Jinglin stabilized his body, climbed up from the low spot, and rejoined the team. His eyes became more determined, as if he did not lose confidence after being attacked by this plan, but instead stimulated his potential and fighting spirit.

They advanced carefully along the path with complex terrain, repeatedly examining every suspicious terrain and various subtle traces that Qin Yuan might have left.

Quietly observing their actions, Qin Yuan was thinking about his next move. Although Duan Jinglin and Bai Shenyang's performances were already quite outstanding, there was still a gap compared with his actual combat experience.

The two sides were in a stalemate in this state. It would be wrong to call it a stalemate. It was more accurate to say that Qin Yuan was toying with them with his absolute strength.

As Qin Yuan left more and more traces, they gradually felt something strange. Although Qin Yuan would leave traces to seduce them before, he only stopped there.

Unlike now, it seemed to be guiding them somewhere.

"The instructor seems to want us to go somewhere? Do you want to follow?"

Zhou Jin was the first to ask the question. He couldn't make the decision alone and had to ask other people's opinions.

After thinking about it, several people decided to follow up and take a look. Judging from these traces, it shouldn't be a trap.

Qin Yuan guided them all the way, and they soon came to a strange place. It didn't look like anything special. The only difference was that the air was not very good.

Just when a few people were confused, Qin Yuan suddenly appeared in front. Seeing their vigilant looks, Qin Yuan blew the whistle.

The word "gather" came out of his mouth, and Yue Ming and others gathered as quickly as possible. They didn't know why Qin Yuan did this, because the training was obviously not over.

Then, Qin Yuan pointed to the ground not far away and asked, "Do you know what is over there?"

Since it was still late at night and there was not much light around, it was impossible to see clearly what was on the ground.

Seeing that several people were silent, Qin Yuan suddenly had a bad smile on his face. It was also because of the lack of light that no one saw his bad smile.

"That's the biogas pool. You need to stand here until dawn. No one can leave without my order during this period!"

When they heard the word biogas pool, they actually understood it somewhat. After all, they had experienced this kind of training before, and it was not unfamiliar.

Soon, Qin Yuan removed the things covering the methane pool. Suddenly, a strong pungent smell hit his face. Even in such an open place, the smell was still unacceptable.

Yue Ming and others were seen frowning, but they still stood tall and silently endured the smell.

Qin Yuan did not leave. Not only was he standing here, but his expression did not change at all, as if he could not smell the smell at all. He could even speak without changing his expression in this environment.

"It seems this is not the first time you have done this kind of odor tolerance training, so you don't need to explain too much."

As he spoke, he walked around a few people. Perhaps because he was gradually getting used to the smell, everyone's expressions were not as ugly as before.

Qin Yuan naturally understands why this is the case. This is a self-protection mechanism of the human body. When the time in a certain environment reaches a certain level, the nose will gradually adapt to the smell and no longer find it unpleasant.

But as long as you leave this environment and come back, even if it is only for ten seconds, your nose will smell that smell again.

Therefore, Qin Yuan wanted to let them receive this kind of stimulation for a long time, either by letting them leave and come back again and again, or by using new smells to cover up the previous smells and let their noses adapt to the environment again.

I originally thought that this training was the same as before, and it was almost done by this time, but I didn't expect that Qin Yuan suddenly took out a can of herring from his backpack.

Judging from the movement of him taking the canned herring, it seemed that there were many other things in the backpack, which made people feel nervous.

Qin Yuan slowly opened the can of herring, and immediately, a strong rancid smell spread quickly, mixing with the original stench of the biogas pool, creating a more complex taste impact.

The surrounding air seemed to become heavier in an instant, and every breath was like inhaling the smell of corruption, which was unbearable.

Yue Ming and others remained motionless and stood upright. Although their brows had long been furrowed, the soldiers' will and discipline allowed them to persevere and not make any other reaction.

Qin Yuan observed their performance with a sneer on his face, obviously very interested in their tolerance. He slowly exposed more canned herrings to the air, and the mixed stench became more and more intense. Strong.

"The next step is the critical moment." Qin Yuan said coldly, his voice low and full of intimidation, "You must learn to stay calm and focused in any harsh environment."

He continued to patrol around them, each step like a blow to their will. The rancid smell of the can did not diminish, but seemed to gradually increase.

The smell stimulated every nerve ending, forcing Yue Ming and others to constantly adjust their breathing rhythm to avoid being knocked down by the sudden nausea.

The sound of footsteps echoed clearly and rhythmically in the silent night sky. With every step Qin Yuan took, the strong stench in the air seemed to become more unbearable.

Yue Ming and others stood in place, still maintaining the posture of a soldier, but their eyes were no longer simply endurance, but a kind of calmness that was almost transcendent. This was a state that could only be reached after countless painful training.

Qin Yuan walked around Yue Ming and deliberately stopped in front of him for a while. The close-range smell impact caused a layer of fine sweat beads on Yue Ming's forehead, but he did not lose his composure because of this, and still stood straight.

Everything on the training ground was immersed in this dirty environment, and every breeze could only increase the transmission of this terrifying mixed breath. Qin Yuan's deep and low voice sounded again, breaking the deadlock at this moment.

"This is not the worst environment on the battlefield," he said. "This is just the beginning."

Qin Yuan stopped at a distance that would make any normal person collapse with a can of herring in his hand, observing everyone's expressions.

Although it was not obvious, the torment in their hearts could be seen from the slightly trembling nose and tense facial muscles. This was what Qin Yuan expected. He needed them to not only remain calm in the extreme environment, but also to think and act.

He raised the can higher and shook it gently, making the strong stench seem to double.

The air was completely filled with this pungent smell, and every tiny movement affected the surrounding air, like raising layers of invisible waves of stench.

Yue Ming's expression was still firm, but the sweat on his forehead was sliding down his cheeks, and the sweat condensed behind his chin and dripped on the ground, forming drops of transparent traces.

He still maintained a standing posture with his back straight, like a stubborn statue. He knew very well that this was not only a challenge to his physical limits, but also a mental test. Every second of endurance was tempering his will.
