Natalie, a witch with big eyes full of shock, was shocked in her heart.

But then, her upright figure followed closely behind the two, although she was extremely shocked in her heart, and the two of them kept coming to mind to inhale and sniff through their noses at the same time.

But following the two of them, she still couldn't believe what she saw.

"Impossible! It doesn't make sense! I'm thinking nonsense!"

"My brother's sense of smell is the strongest, which is one of the key reasons why he is called the Red Dog by other demons, because his sense of smell can help him hunt down enemies in all kinds of harsh environments. “

"This kind of ability, among the demons, there are many people, but if you talk about the strongest, my brother is undoubtedly the one who stands at the top, his sense of smell, can distinguish all kinds of smells, even if ordinary demons can't smell at all, he can. “

"But why did Chen Yongsheng move before him?"

"Is it luck? Impossible! When the Beast Spirit Martial Artist uses the aura to propel his body to accelerate forward, unless he has already determined that it is in this direction, how can he move first?"

"How did he know for sure?"

"Like my brother, is it through the sense of smell?"

"Could it be?"

"This guy who came to fight the princess is obviously targeting me, the ground is not shaking, the walls are not shaking, there is no abnormal vibration in the water, and there is no fluctuation of aura."

"In the winding drainage system, even if Chen Yongsheng can see through, he probably won't be able to see through all the things behind the concrete walls, so how did he do it?

"Smell! It must be smell! In such an environment, only the sense of smell can find the opponent's position!"

"Could it be that Chen Yongsheng's sense of smell is stronger than my brother's? How is this possible? This is absolutely impossible!"

Natalie, a witch with a graceful figure, followed with shocked eyes, behind the two.

At this time, in order to avoid collisions, he had jumped into the sewer, and the handsome grinding man who was tracking from the other side, his mood at this time was even more shocked than that of the witch Natalie.

At the beginning, he really instinctively thought that Chen Yongsheng moved before him, just by luck.

But next, a couple of forks in the road.

He's already found out.

Every time he wanted to change direction,

Chen Yongsheng will be one step ahead and change direction in advance.

"Is he also proficient in smell?"

"Impossible! Beast Spirit Warriors have always been very good at distinguishing smells, and they are particularly bad at taste analysis, unless they are the kind of people who have the talent of strange beast spirits, otherwise under normal circumstances, they can distinguish more than 100 kinds of flavors, and this ability to track the enemy with subtle smells is achieved by distinguishing the odor molecules in the air, this is my proudest talent, how can he do it?"

Thinking in his heart, the handsome demon began to try, deliberately half a beat slower,

That is, every time he reached a fork in the road, he did not make any preparations to change direction, not only did there be no change in his body, but even the change in aura was hidden by him.

But as the chase unfolds.

In his heart, he was more and more shocked.

"I don't think it's possible, but it can't be wrong!"

"This Chen Yongsheng has a sense of smell that is not lost to me!"

"Only by being able to clearly distinguish from the air which odor molecules are left by the enemy, can he make such an accurate judgment in the dark, impossible, absolutely impossible, I am the strongest in this regard!"

Majin brothers and sisters, at the same time with shocked eyes.

Looking at the hint of the purple shock value of the two of them, Chen Yongsheng's heart was also helpless.

"Shock from Natalie the Witch, +100+100+100+100!"

"Shock from Majin Eric, +100+100+100+100!"

The purple shock value of the two brothers prompted, one after another, which made Chen Yongsheng very helpless.

As the strongest veterinary physician on the planet, Chen Yongsheng knows all about any animal.

Take the human sense of smell, for example.

Theoretically, the human sense of smell can distinguish more than 1 trillion scents.

But usually, the environment in which you live will be mixed with various flavors, and too complex tastes, well, will affect the normal judgment of human beings.

So gradually, the human sense of smell has become less acute.

But even so, the least sensitive person can distinguish 80 million scents.

And people with a real keen sense of smell can distinguish 1 trillion total smells through their sense of smell.

It's just that more often than not, people like to attribute the taste to their liking or disliking it, and nothing else.

There is no way to distinguish the destination of particularly light flavors.

And Chen Yongsheng exchanged the god-level talent in the Heavenly God Plan, the Nose of the Heavenly God, after smelling the incense.

In the past, I just felt that it smelled good or bad, or it was relatively close, the smell of a certain object.

It has become a clearly visible floating in the air, odor molecules.

And as long as Chen Yongsheng focuses on one of the flavors.

This kind of smell does not emerge from the thousands of smells in the air.

Not only can it be clearly distinguished.

At this moment, it is more like a small plane with smoke, in the air, leaving his ins and outs, that is to say, unless this guy gets rid of all the smells, even if he escapes to the ends of the earth, he will not be able to escape Chen Yongsheng's tracking.

So, at this moment.

underground, within the drainage system, the role of the eye is small,

The perceptual effect of Reiki is also extremely limited.

The guy who snatched the little wild cat and the fat tiger was very careful, and was obviously completely prepared.

The only thing that can continue to track them is the smell.

In such a situation, if it had been placed before, Chen Yongsheng would definitely have a black eye, and he didn't know what to do at all, so he could only be at a loss.

But now it's different.

Chen Yongsheng can track the enemy's whereabouts very clearly.

This kind of power, which seemed to have mastered everything, made Chen Yongsheng suddenly understand a little reason, why Eric, the brother of the demon brothers and sisters, was so arrogant, because this ability was really too powerful in a specific environment!

Thoughts are only a moment, just a few breaths.

Within the underground drainage system, three people who had been chased for at least a few kilometers came to a sewage fork again.

And this time, Chen Yongsheng felt very clearly that among the originally tracked flavors, there was a particularly slight taste, which went to the left side, and the originally tracked flavor went to the right side.

It feels like this person who escaped, after throwing his clothes, shoes and hat, to someone, or something, and told them to go to the right side, and this person, the golden cicada broke out of his shell and went to the left.

But at the same time as Chen Yongsheng's decision, the demon Eric had already gone straight to the right side, and the witch Natalie was also suddenly excited, following behind his brother.

"There's a tremor, the bastard is ahead, he can't run!"
