These black fogs are also poisonous, and he feels that it is these black fogs that cause damage to the environment, not damage to the atmosphere, after all, the ground in the atmosphere is so far away, and after they deal with the big bugs, they can see the aura that the big bugs have become to repair the atmosphere.

No matter how you think about it, the only possibility is that the layer is actually a protective layer built by the big insects, and the protective layer absorbs the ultraviolet rays in the sun and becomes useful nutrients for them.

They come out at night, not only to absorb the nutrients in the protective layer, but also to use the gambling gas they produce to keep the protective layer running normally.

However, after they are purified, they will become aura and destroy the protective layer, so that the protective layer will weaken little by little until it finally disappears.

Mu Wanqing fell silent, as Jiang Yuze said, it was not the atmosphere at all, but the protective layer, she also knew that the atmosphere could not be so close to the ground, and standing on the ground, how could she see the atmosphere?

"That's right, it is indeed a protective layer built by insects, when the big insects opened the spatial teleportation channel and came to this world, the first thing they did was to build a protective layer to prevent the sun from causing damage to them.

The sun I am talking about is what you call ultraviolet rays, and those big insects are afraid of the sun, and they can't survive under the sun, and they don't come out until night.

The bad environment here has improved in recent years, because of the purple ore, the purple gas in the purple ore can play a destructive role in the protective layer, but the purple gas in the purple ore alone is not enough, the teleportation channel must be closed, so that the big insects can't come over. ”

An old man walked out slowly and gave some simple explanations, letting Mu Wanqing and Jiang Yuze know that what they guessed was the truth.

Mu Wanqing and Jiang Yuze subconsciously became vigilant when they saw the old man of the fairy wind bones, and Jiang Yuze also asked, "Who are you?" ”

"It doesn't matter who I am, the important thing is that we all have a common purpose, which is to destroy the protective layer built by the big bugs, destroy the teleportation channel, and make the world normal." The old man said.

"Old gentleman, listen to you, you have been fighting here alone for a long time, so have you found the purple ore?" Mu Wanqing asked.

"It's purple ore found, but it's very rare, and there are only two left on me at the moment." The old man replied, his eyes were full of worry, he knew the role of purple ore, but once the purple ore was exhausted, then there would be no way to deal with the big insects, and then the environment here would deteriorate again.

From the current point of view, Mu Wanqing knew that the old man was not an enemy, so she took two pieces of purple ore and threw them to the old man: "We all have some purple ore on us, and we can deal with it for a while." ”

"Thank you, since you still have purple ore on you, then I will get rid of you here for the time being, I also have to help my companions, this teleportation array is available in the four directions of southeast, south, and northwest, and there are seven teleportation arrays in each direction, arranged according to the direction of the seven stars."

The old man told them what he knew, lest they be caught off guard by these big bugs.

"There are four directions, southeast, northwest, and ......" Jiang Yuze's face became solemn, all he and Mu Wanqing could feel was this direction, since it was in all four directions, why couldn't he and Mu Wanqing feel it?

Could it be that they didn't cultivate enough, so they couldn't feel it? Or is it something else?
