It's a night of no rest for Maureen. He went to the wooden box and squatted down. If Chu didn't find the key, could he break the wooden box open?

all is quiet at dead of night. After all, in this silent night, the sound of smashing the box will be particularly abrupt.

But if he didn't break the box, Maureen would never be at ease. What exactly is in this box?

In the end, Maureen didn't break the box. It may be that he thought that the night was too quiet, but any action he made would reverberate in the whole valley. So he didn't do it.

I don't know when he fell asleep on the box. Maybe it's because his nerves are too tight and tired during this period of time.

By the time he woke up, it was already bright outside. Chu Yinglong's key may not have been found, because at this time, he did not see the king of medicine or Chu Yinglong asked him to go.

If you don't find the key, just wait. After all, the box is so big that you can't run away, because now Maureen has a very important thing to do.

He remembered that when he came back last night, he found that all the little black insects in the bottle had died. The inexplicable dead insects make Maureen flustered.

Now he has to go to the sulfur pool to have a look.

Before, he and Yao Wang sealed the whole sulfur pool with big stones. He had to move the big rocks before he could get in.

Just as he put his hand on the stone, his hand drew back. He was afraid that the big stones were covered with the little black insects. For a moment, he hesitated.

What can we do? Maureen lingered outside the cave for a long time. He wants to see what he can avoid.

All of a sudden, he thought that when he used the tranquilizer before, these little black insects were very slow. Yes, yes, yes. Tranquilizers.

When I used tranquilizers before, I found that these things moved a lot more slowly. But he used to use water, and now he needs powder.

So he went back to the lab, put the powder of tranquilizer powder and water mixture evenly on his hands and bare arms, and then moved the big stones.

Fortunately, when the big stone moved away, he did not find any small black insects on the stone. Until he came to the sulfur pool. He just slowly discovered the trace of those black insects.

The water in the pool is almost eaten by them. It should be said that the water gushing from the bottom of the pool can't keep up with the feeding speed of the little black insect.

And compared with what we saw last time, the number of these insects seems to have increased. Maybe it's because there's a tranquilizer spray around, so these little black bugs don't have much activity.

Of course, it is also possible that the water in the sulfur pool is drying up, so the insects are not very active.

Anyway, there is no sign of the bug spreading around the sulfur pool. That's a good start. At least Maureen doesn't have to worry about bugs.

Through observation, Maureen found that these little black insects were still very strong, and the signs of life were very complete, which was very different from what he had brought back before.

In order to study why the insects he brought back died, he put them into two different containers.

He made a very dense hole in the top of one of the utensils for the insects to absorb oxygen, while the other was completely sealed.

He took the two utensils back to the lab together. At the same time, in order to prevent the spread of small black insects, he put the two containers into a large sealed box.

He put the sealed box directly on the test bench. He needs to observe whether these things will die because of lack of oxygen, or because of something else.

But this observation will take a while,. When he came back with the bottle, it took him three days to find that the insect had died.

Now he doesn't have the time to wait. He thinks that if he doesn't speed up, Chu Yun may be too late. What can he do?

If you want to get the experimental results, but don't want to wait, maybe Maureen has only one way now, that is to vacuum.

He pumped out all the air in the bottle, so that the oxygen in the whole bottle gradually disappeared. And then see if the bugs die slowly because they don't have oxygen.

Because he just wanted to prove that these bugs would die without oxygen. So just take all the oxygen out of the sealed little jar.But the experiment made him find that these little black insects are still alive and kicking.

Maureen has been watching, these little black insects do not seem to lose oxygen, and become slow, or dying. On the contrary, they all behave the same with oxygen.

What on earth caused the little black bug to die? Maureen was particularly surprised that if it had nothing to do with oxygen, there would be some external factors.

Thinking of this, Morin can only take the dead little black bug to the laboratory for research.

Unexpectedly, when he was dealing with the little black insects, he found something like alum in their bodies.

Alum? Maureen wondered why there was alum in the body of these insects? In Molin's lab, alum has never been used before.

So it's impossible for these insects to suck alum in the lab. But he did find alum in the insect's body. Who put alum here.

Since Maureen has doubts, he must find out. So he took the whole box and did the same research.

Sure enough, inside the box bar, he also found the existence of alum.

There is alum on the box, which means that the person poured alum into the box. But who is it?

Maureen tried to think back to the people who had come to the medicine house these two days, and after thinking about it, only he and the king of medicine had touched the box. Who else would touch the box but the two of them?

Is the person who puts alum into insects the king of medicine? Molin did not believe that if the king of medicine wanted to harm Chu Yun, why would he work with him to study the antidote for Chu Yun?

Moreover, if the king of medicine really wants to destroy the evidence, he can't be so stupid that he can be suspected
