The reunion between old friends was suddenly interrupted by a stiff voice, and the atmosphere was suddenly extremely awkward.

Li Xun stopped, looked at the middle-aged man in a combat uniform who didn't seem to make any expressions, and didn't see the slightest clue, but saw that he had a bulging bag on his waist, which should be a gun.

But Li Xun's nose twitched, but he smelled a kind of engine oil mixed with bloody breath from him. Not only that, but I also smelled potassium nitrate, charcoal from his body.

Just smelling these breaths, Li Xun immediately subconsciously took a step back, this man is dangerous.

From the engine oil mixed with the smell of blood, it is not difficult to analyze that he has at least a dagger or a sharp knife on his body, which has killed many people. Only a knife that has killed people will leave a smell of blood on it. And this is a good knife, because only a good knife will be applied with knife oil on a regular basis.

This kind of knife oil is similar to engine oil, the main purpose is to prevent rust, and make the blade always shiny like silver, will not produce a dull feeling, sharp abnormal, it is easier than other knives to insert into the human body, without being stuck in the muscle.

And the potassium nitrate and charcoal shocked Li Xun's heart, and he only felt that he was a madman.

The smell of the gun is mainly made up of nitrate, which is the smell of burned nitrate, not the smell of this potassium nitrate.

With two chemical elements, potassium nitrate and charcoal, there is only one possibility for this combination.

This man was carrying a grenade, or an area of destruction weapon such as an explosion.

How can anyone carry a bomb with them, and even fewer people carry grenades. The soldiers of the Siberian Tiger Special Operations Brigade did not dare to carry them with them, and they were all put into multifunctional combat waterproof backpacks, which were strictly controlled and strictly preserved.

This kind of thing is too lethal, and under normal circumstances, how dare anyone carry it with him.

If you accidentally go off the fire, there is absolutely no living mouth within a radius of more than 100 square meters.

This man actually carried it with him, and if Li Xun hadn't smelled the smell, he wouldn't have even been able to see where he was hiding with just a pair of eyes.

He was wearing a loose combat uniform, except for a slight bulge on his waist, and there was not the slightest hint of that kind of large-scale lethal weapon hidden on his body.

You have to be far away from this kind of person.

Li Xun is not afraid of being hostile to him, but what he is afraid of is that if there is a conflict with him, he will drag you to the end. In other words, I am afraid that the things on his body will accidentally go off, how wrongful this is, and I will panic.

On the other hand, Li Xun's inadvertent behavior of opening a safe distance also attracted the attention of Captain Zhang, and his eagle-sharp eyes swept Li Xun, but his heart was even more shocked than Li Xun.

Because he saw that Li Xun's eyes flashed with astonishment at that moment, and then he saw Li Xun's eyes scanning his body full of doubts.

Just seeing Li Xun's expression, Captain Zhang was a little shocked. Could it be that he sees what's in me?

It's impossible, and his own hiding methods are extremely skillful. Sometimes when accompanying an important person on a private visit, on the one hand, you must carry a weapon with you to protect the safety of others, and on the other hand, you must not let others know that you have a weapon, so as not to cause unnecessary trouble.

Therefore, Captain Zhang's method of hiding things can't even be found out by airport security.

Could it be that this kid can see it at a glance?

Even if he didn't see where he was hiding, but he could see that he had it in him, it was a terrible thing.

For a while, Captain Zhang also subconsciously turned around and faced Li Xun in a more nervous way, although he was holding Expert Xu with both hands, his legs and muscles in his body were ready to fight at any time.

In the flash of light, Li Xun and Captain Zhang have clashed several times, and no one knows about all this.

Expert Xu looked at Captain Zhang who was standing between him and Li Xun, and his face immediately sank: "Xiao Zhang, what do you mean?"

Captain Zhang replied expressionlessly: "The river is dangerous, you can't approach it." ”

"Oh, can't I even see my old friend? Outsiders say that our Chinese Academy of Sciences has an old-fashioned brain, I found that your brain is even more old-fashioned than ours, this time you have made a major discovery, it would have been an exciting good thing, can you not be so disappointed?"

Although Expert Xu complained, he also said it tactfully, and he didn't really get angry, because he knew Captain Zhang's identity, after all, it was also for their good.

Captain Zhang said, "You can't go to the river, but I'll allow you to ask your old friend to come over." You must stay at a safe distance of more than fifty meters from the river. ”

Expert Xu sighed helplessly, and beckoned to Li Xun apologetically: "Li Xun, are you coming, I haven't seen you for a long time, you come." ”

Li Xun glanced at Captain Zhang defensively, but in an instant, he put on a smiling face again, and walked around Captain Zhang in a safe way.

One old and one young, their hands clasped together.

Expert Xu kept holding Li Xun's hand, and said excitedly: "Oh, I haven't seen you for almost ten years since I said goodbye last time, right? ”

Li Xun actually had some emotion: "Yes." Is Professor Qu okay?"

When Expert Xu heard this, he was silent for a moment, but his eyes turned red, and tears began to roll. This emotional appearance stunned everyone. This high-ranking expert Xu can be an old friend with Li Xun, which already stunned everyone, and what is even more shocking is that the friendship between the two is still so deep?

Li Xun was stunned and asked tentatively, "What's wrong?"

"Alas, eight years ago, as soon as our expert group returned to Beijing, Lao Qu had a heart attack. Before the plane got off, it drove to the west at an altitude of 10,000 meters. ”

Li Xun sighed: "It's a pity." ”

Instead, Li Xun approached Expert Xu again, and was about to whisper, when Captain Zhang suddenly stepped in and said coldly, "Please keep your distance from Expert Xu." ”

Li Xun hadn't reacted yet, but Expert Xu couldn't hold back any longer, and exploded on the spot: "Enough, do you have a problem, you, I know that you work hard to do security work, and your nerves are tight, but you can't be a soldier, I'm here to investigate and study, not to be under your house arrest." ”

As soon as Expert Xu became angry, the members of the expert group who came with Lao Xu immediately surrounded him, some persuaded him not to be angry, and some followed Captain Zhang not to be so rigid.

In an instant, Captain Zhang seemed to have become the finger of a thousand people, but his face still did not change.

Li Xun glanced at him and approached Expert Xu again, but this time Captain Zhang pretended not to see it, it seems that what this Qianfu is pointing to still has an effect.

Expert Xu pricked up his ears, but only heard Li Xun ask: "How is that little beast?"

When Expert Xu heard this, his face immediately changed.

PS: This is the first chapter of today, and there is another chapter at noon and in the evening. Three more, can it be regarded as a plus change? There are two reasons, first, it just happens to be a transitional chapter. Second, you're pushing me too hard and asking me to work more all day long, so I can only sleep a few hours less.
