After a brief analysis, Li Feng found that this poison was obviously eroded by everything from the sea, land and air. The earth, ocean, air, and ubiquitous toxins caused this polluted world.

At present, all the plague demon kings in the waters have been killed, and the earth has just been eliminated forever. The increase in toxins in the air means that there is a more powerful plague demon king who is constantly creating a large amount of toxins into the air.

How to find this one, Li Feng just feels the wind. If he wants to spread better, the other party should choose the most powerful place for the place to settle it.

Close your eyes and feel the direction of the wind blowing.

That's there!

After opening his eyes, Li Feng had already aimed at this goal. It was this towering mountain with several relatively low mountain passes in the middle of its continuous mountains. The powerful wind kept blowing from these mountain passes. Li Feng now has sufficient reason to suspect that these mountain passes have his own goal this time.

Looking over, you can still see some blurry outlines. Use teleportation back to the location of the cave just now, which belongs to the foot of the mountain, making it clearer.

Looking up, at the end of one side of the mountain, there was a canyon-like terrain that looked very much like the wind vent that Li Feng imagined. Maybe it was there, and Li Feng, who had a hint of expectation, decided to explore first.

It belongs to the end of the mountain, and there is no consideration of how the surrounding monsters are. This time, Li Feng tried his best to travel for speed. The main reason is that the time is still a bit late, and he wants to set up camp before dark or conduct a certain degree of investigation. He doesn't want to engage in night combat, and compared with humans and animals, night combat is definitely a disadvantage for humans.

“There is a problem here!”

Just as he was rushing around the foot of the mountain, after a long distance, Li Feng happened to use his perception to explore the surroundings. Anyway, he didn't plan to fight again today, so he could still squander his mental and physical strength.

There was an ordinary mountain in front of me, but my perception kept telling me that there was something inside. Even if I were separated by a large number of rocks, I could feel the terrifying toxins inside.

What exactly is it? Li Feng carefully stroked the mountain in front of him, but had even more strange perceptions.

Li Feng has touched the rocks of a mountain many times. It is just that kind of normal rock feel. Although he cannot describe the touch of a rock, he can clearly feel it. Or in other words, he can know what the touch of a rock is, but no one can describe it.

But the piece in front of me felt like frosted glass, and it was rustling and not the feeling that the mountain should have.

With a bang, Li Feng attached Han Bing to his fist and punched the "rock" in front of him.

Only a crisp sound was heard, and the "rocks" in front of them shattered and fell on the ground one by one.

It's really a material like frosted glass, hiding the contents inside.

There is a door more than three meters high inside, with five concave marks on the door. If you gently stroke these marks, you can feel that it has a certain magical sense. It should be necessary to have extremely five keys of similar shapes, and the material must be symmetrical before the door will be opened.

Five pieces...the five major plague demon kings... Could it be that what key would be dropped if the plague demon kings were killed? Li Feng was full of questions.

But I didn't notice any drops before. I didn't care whether there was any drops. When Li Feng thought of this, he felt a bad premonition in his heart.

In short, the location here may be related to the final leader, and it is 80% possible that the final leader is here. The rich toxins transmitted from the inside really make Li Feng feel terrified.

Continue to act according to the original plan, and after another period of running, I successfully arrived at the location of the gorge.

As a result, when Li Feng first arrived, he discovered that the mission goal was not necessary to find it.

There was a wide stream of water in front of me. When Li Feng sniffed it a little, it had the unique smell of sea water. Then this place was connected to the sea I saw before, not a river.

There was a steep gorge in front of me, and a huge eagle-shaped creature was living on the cliff.

The eagle stood there, looking around from time to time, and then dealing with the matter in front of him.

There are all kinds of birds around him carrying various things for the eagle, and there are many things. Li Feng can see dead branches, shells, dead leaves, thatch, soil blocks and other things.

These things are all filled with toxins. Compared with the previous few, this eagle is not picky about food at all and collects all the toxins.

There were some bottles and jars in front of me, and the eagle sucked poisons and placed them in various bottles and jars. Covered with the lid. Although it did not have human hands, its sharp mouth was quite flexible. It shook it with its claws a few times, and then placed it there in exquisite detail.

Then find a bottle that should be the one that was stored before, open the bottle mouth, and aim it at the gas released from the outside. Open more than ten bottles in a row, and after releasing the breath inside, clean up the toxic substances in it, so that an empty bottle is obtained and other toxins continue to be placed.

After all the gas in the bottle was released, it flapped its wings to let the transparent gas spread along the force and spread towards Li Feng.

It was obvious that the poison gas was a little more vicious, and the blood that continued to fall had a sharp increase. Then it slowly returned to normal again, and these toxins were brought to everything around by the wind.

This plague demon king relies on this method to gradually pollute the air and the toxins become deeper and deeper.

Should I take action now? Looking at the gradually falling sun, Li Feng hesitated.

I originally thought that the last plague demon king would be difficult to deal with. Other plague demon kings all appeared in pairs, but they appeared alone, which must be very powerful. So at the beginning, I decided to stay for tomorrow to solve the problem, so I could restore my energy or something.

But now it seems that the main advantage of this plague demon king is that he can fly, and the geographical location of the canyon is quite dangerous. If he wants to attack this guy, it may be really difficult for most people.

But who is Li Feng? He is an invincible magician. Just this guy, he has a few ultimate magic and doesn't believe that this guy can survive. Even if he doesn't use ultimate magic, gravity is enough to drink a pot. The flying unit is generally low in defense, but its flexible air figure is very difficult to hit. Especially for some melee bloodlines, he is really desperate for such an existence.

But I just consumed quite a lot of mental power. If I really didn't kill successfully, I was afraid I would fall into danger.
