Some people have been here, and it is full of stones and dirt, and the traces of other people's walks are indelible.

However, Wu Yi saw that the footprints were only the footprints that went out of the cave, but there were no footprints that entered, which showed that this person had been in the cave all along, and only came out after the bloody mouth monster rushed out.

Then there are no traces inside, I'm afraid it has been erased, but it doesn't matter, small traces can erase big ones, and big traces are afraid that they are not so easy to cover.

After entering the cave, there are some traces in the cracks of the stones inside, that is, the traces left by those black beetles. Those beetles must have lived in these crevices for a long time.

However, Wu Yi did not see the beetle larvae in these crevices, and no other traces appeared, indicating that these beetles were very likely to have migrated here.

And when they leave the area where they lived, they have lost their original fertility, so the total number of beetles that have been relocated here should not change.

It's just that what Wu Yi doesn't know is why these beetles have become the catalyst for the resurrection of the Bloody Mouth Monster. Wu Yi now knows too little information, and he can't find out what is wrong with it.

Of course, the investigation that Wu Yi wanted to do was far from over, and continuing to walk into this cave, Wu Yi found some small holes, and it took a person to bend down to get into them.

Of course, not all holes need to be entered by Wu Yi, he only needs to find a place with some traces of wear and tear to enter.

Of course, there was only one such cave, and it didn't take long for Wu Yi to find it. Wu Yi summoned his green-haired phantom beast, and this little guy looked very happy.

Since Wu Yi was afraid that his identity would be exposed, he rarely summoned the green-haired phantom beast in public, and today Wu Yi explored the way first, and there was no one around him, so Wu Yi summoned the green-haired phantom beast.

This green-haired little guy jumped up and ran in front of Wu Yi, for Wu Yi's very crowded passage, for this little phantom beast, there was not the slightest pressure at all.

Of course, if he encounters danger, Wu Yi will not be very worried at first, and Wu Yi is very confident in the green hair's ability to resist blows.

It didn't take long for Wu Yi to find that the green-haired little phantom beast had come to an end and stopped, and the little guy's mood was very relaxed.

Indicating that there was no real danger inside, Wu Yi half-bent over and crawled over, and found that this place was an egg-shaped space, with blue powder on the stone walls.

In the middle position, there is a wooden disc, there should be something to rest here, Wu Yi carefully touched the powder on the wall, and found that he had not seen such a thing.

At the same time, the king, who had fled to the outskirts of Wujiao Mountain, saw a stone in his hand turn from white to red, and he knew that someone had entered his trap.

So he crushed the red stone in his hand, and Wu Yi, who was still in this egg-shaped hole, suddenly felt a large amount of heat around him, for such a sudden situation.

Wu Yi was already at a loss, he and his phantom beast Green Hair both sensed the aura of danger, and Green Hair's perception of danger was a hundred times more sensitive than Wu Yi's.

So at this time, the green-haired jelly-like body suddenly swelled several times, and instantly wrapped Wu Yi in his body.

And at this time, Wu Yi could see through the green-haired translucent body that the blue powder he had touched just now was instantly burning.

This egg-shaped space instantly became a furnace, enveloping Green Hair and Wu Yi in it, and this flame continued to burn out of the cave.

However, the power of this flame burned fast and extinguished very quickly, and before Wu Yi could react, he could no longer feel the burning sensation around him.

This is all the credit of the green hair, of course, the air here has been burned out, and Wu Yi, who was wrapped in the green hair, actually found that the green hair can also produce oxygen in the body.

It's just that it's very weak, and he can barely use it by himself, and Wu Yi doesn't dare to move at this time.

Because of the movement, Wu Yi found that one more movement would consume more oxygen, and it was better to sit there and breathe slowly. In fact, Wu Yi did the same.

The energy of this flame did not produce the power of the explosion, so Wu Yi felt that the place at the exit should not have collapsed, and he was waiting for the oxygen to slowly flow into the cave again.

Moreover, Wu Yi was also able to communicate with Green Hair through mental induction, knowing that Green Hair's state at this time was not very stable, and it could not be maintained for a long time.

Because the green hair at this time was the oxygen needed in his body, and a part of it was given to Wu Yi's body, so Wu Yi did not have a lack of oxygen for the time being.

Of course, they are interdependent now, but it was the same before, but now it is something like reliving it.

At this time, outside the entrance of the cave, Pojun Hongsha was looking at the black entrance with a worried face, and a fire dragon suddenly appeared here just now, and everyone knew that something might have happened inside.

Pojun Hongsha also wants to go down and take a look at the situation inside, but she also knows that this is a very dangerous thing, and her life safety is not only responsible for herself, but also for her country.

So she tried to restrain her urge to enter and take a look, but ordered her men to find a few dead branches, light them and throw them into the hole.

If the flame goes out, there is still no air inside, and if the dead branches continue to burn, it means that there is already air inside, and you can enter it to check the situation.

After waiting for about twenty minutes, he found that the dead branches could continue to burn, so he immediately organized people to enter it, and he was also very worried about Wu Yi's safety.

So despite the obstruction of his subordinates, they also wanted to enter it, but after compromise, the broken army red yarn could only hide at the back of the team, and after entering it, they found that the traces inside had disappeared.

On the stone walls of the cave, only a large amount of black remained, like the ashes of the pot after the iron pot had been baked. These people didn't walk a few steps, and most of them were already looking dusty.

And the person who walked in front immediately became vigilant, because he noticed a strange green thing in front of him.
