The time with his family was short-lived, and at noon the next day, he needed to set off to inspect the northern region. However, Jiang Yuan didn't have the sadness of parting, because it didn't take too long for him to travel all over the north, so it was easy to come back, and the time was only delayed in finding the fourth-order mutant beast and killing it.

Fourth-order king-level mutant beasts, they have a strong sense of territory, such as the Blood Flame Wild Lion, which occupies the area of Qinglong Mountain, so there will be no second fourth-order king-level beast here.

However, for the sake of absolute safety, Jiang Yuan still came to Qinglong Mountain as the first stop, and casually cooked three mutated creatures at the peak of the third order, officially announcing the occupation and development of Qinglong Mountain by Gangtie City.

Taking out the map and determining the direction, Jiang Yuan began to set off towards the next location.

The Black Water Swamp is another new landform formed after tomorrow, and similarly, there is a fourth-order king beast entrenched in it.

The Blackwater Swamp is near Dragon God Island, only ten kilometers away from Dragon God Island, which can be said to be dangerous for the humans in Dragon God Island.

This Blackwater Swamp located on the south side of Dragon God Island was the first fourth-order forbidden area that Dragon God Island asked him to settle, in addition, there was also a fourth-order forbidden area with a king beast on the north side of Dragon God Island.

Although he was absolutely confident in his abilities, Jiang Yuan still did not directly teleport into the swamp.

No matter how you say this, it is also a king-level battle, if you are not careful, it is death, if you are easily killed like this, you are looking for death.

Jiang Yuan came to the sky outside the swamp, and habitually directly used the giant wood, like Sun Wukong's wishful stick, and stabbed directly into the swamp.

The giant tree is something that can hurt the fourth order, and of course, in a special realm, it can be easily destroyed.

A group of people living in the giant wood forest, Jiang Yuan told the alliance search and rescue team the general location, and they should be able to find them quickly.

The search and rescue team of the alliance is a newly established unit of the North China Alliance, which is subordinate to the presidium and is reorganized by the previous exploration teams of each city.

The weight of the giant tree was so great that even in this extremely buoyant swamp, a large hole was smashed out. The swamp fluctuated for a while, and the giant trees plunged deep into it, followed by a brief lull.

With such calm, Jiang Yuan not only did not approach again, but hid away again.

If something goes wrong, there must be a demon!

Sure enough, in the next second, the surface of the swamp suddenly exploded, and a huge black-gray toad appeared in front of him.

The black-and-gray giant toad was the size of a heavy muck truck, with a tubular poison sac on its back, apparently a jetting device. It had four eyes, round and round, and its body was undulating, with large expanses of muddy water being blown in all directions.

There was also a foul smell that came out of it, and this stench almost covered up all the smells, and the first time Jiang Yuan asked, he immediately ran farther away, but his face was still smoked and turned green!

With his current knowledge, he really couldn't imagine what words could be used to describe this kind of taste that makes people go directly to the immortals!

Jiang Yuan originally wanted to see what kind of attack principle the poison sac behind this thing was, but now he lacked the interest to stay here for even a second longer, so he decided, flashed over and killed it, and then quickly walked away!

As if feeling threatened, the highly poisonous toad looked at Jiang Yuan, violently agitated its back, and two poisonous water balls flew up, but instead of hitting Jiang Yuan, they collided in the air, and the two exploded in the air!

"! Damn! Jiang Yuan quickly flashed away in a matter of seconds, and then looked back at the space.

At this time, above the swamp, a black fog was filled, and the figure of the highly poisonous toad was completely lost, the black fog was not an ordinary fog, but a poisonous gas that emitted a foul smell, and this area was completely shrouded in poisonous gas.

The realm space of the first order of the king was only more than 1,860 meters in radius, but the poisonous gas range of this highly poisonous toad had reached more than 3,700 meters, obviously, this was a terrifying existence of the second order of the king!

At this moment, Jiang Yuan was also unsure if his spatial blade could cut through the skin of this king-level mutant beast.

Moreover, he couldn't enter this stinking space realm, and he didn't know if he could live close to it. It's more likely that he hasn't completely approached yet, and if he hadn't killed the highly poisonous toad, he himself would have been turned into pus by the poisonous mist!

For the experiment, Jiang Yuan grabbed a half-dead second-order mutant insect and threw it into it, throwing it on the periphery.

Suddenly, the shell of the mutant insect began to quickly turn into pus, and the poisonous gas entered its body, corroding from the inside out, and completely blending into the mire!

What can I do about this?!

The first fourth-order mutant beast that went out to exterminate actually made itself deflated, and if people knew about it, their image would be completely ruined!

Of course, he didn't have the urge to rush straight in.

Jiang Yuan took out some more things, temporarily sealed his nose and mouth, and took them to the periphery of the poisonous mist space to start the experiment.

In the end, he found that all meat, biological cells and other things were eroded, and metal was corroded very quickly, but he found that the poisonous gas had no corrosive effect on plastic, and large pieces of plastic did not appear to be corroded in it.

The plastic bags are also not corroded!

He put another piece of meat in a plastic bag, put it in the poisonous mist, and after a while, it didn't change!

It seems that plastic can isolate this toxic fog. This is the conclusion reached after the Jiang Yuan experiment.

So, he rummaged through the space carefully, and actually found an oversized plastic bag, and he didn't know what the big black plastic bag was used for.

Jiang Yuan didn't care about this, so he put himself in, tied it up from the inside, and sealed it with a large tape.

With his current physical fitness, he has no problem not breathing for half an hour, and now, he doesn't need that long.

Using perceptual space and teleportation, Jiang Yuan quickly came to the depths of the poisonous fog and found a highly poisonous toad that was breathing poisonous gas with a large mouth exposed.

"Looking" at it breathing that extremely corrosive poisonous gas so easily, Jiang Yuan couldn't help but admire: "How resistant to corrosion this body is!" ”

After sighing, Jiang Yuan shook his hand and slashed at it with two spatial blades!

"Gollum!!"

The poisonous toad jumped out of the swamp violently, and the two wounds on its head, which were neither shallow nor deep, were bubbling with thick green blood, and this blood, as soon as the poisonous mist was touched, turned into white smoke and disappeared!

The damage of the space blade to this guy is limited, after all, he is only a first-order king, and this toad is a second-order existence, Jiang Yuan no longer hesitated, and used the strongest attack method-

Space shattered!
