Lin Chenxing, who was drifting on the black mud swamp with the advantage of his body skills, unsurprisingly heard a muffled sound from behind him.

The figure remained unchanged, his head was slightly deflected, and with the help of his afterglow, Lin Chenxing saw that Liu Feibai, who was covered in black armor, was straight into the black mire, reaching his chest, and was still slowly sinking.

"It's okay, this depth is okay!"

After briefly confirming the situation, Lin Chenxing couldn't care about anything else, and the moment he borrowed his strength, he used his long sword to constantly provoke black mud and pour it on his body.

After repeating it several times, he was covered in stinky mud, not even the wounds on his face and body. The smell blended in with the smell of rotting plants pervading the swamp.

Just when Lin Chenxing was running wildly, Liu Feibai was still stuck in the black mire and couldn't get out.

According to the Blue Star people, this black mud is one of several types of non-Newtonian fluids, and it belongs to the type that eats soft and does not eat hard. To put it simply, if you stir hard, the black mud of the swamp will be thinner and less forceful, which is why ordinary people fall into the swamp and the faster they struggle. This property and its twin brother, the non-Newtonian fluid, which becomes extremely hard when subjected to force, fall into two extremes.

It is unlikely that Liu Feibai knows what a non-Newtonian fluid is, but he understands the fact that the more he struggles when he falls into the black mud, the deeper he falls.

Although as the second son of the Liu family, he had never been to this fog swamp where pickled toad catchers were mixed before, but he grew up in Lishui Town since he was a child, so he naturally knew these basic common sense.

Now he couldn't be sure how deep the black mud edict was under his feet, and he didn't dare to act rashly. In this situation, even if he has great strength, he can't move, unless his current strength can burst the entire black mire with a single blow.

Black Armor has a strength bonus to him, which allows him to gain extremely fast speed on the ground with the help of strong recoil force, but this recoil force needs to be generated by his body movements, which means that he must have a power point.

This is different from the propulsion system of jet aero engines or Iron Man armors, and if it is a jet propulsion system that directly uses high-temperature air or ion currents to generate thrust, this black mire may not be trapped.

For example, if the knees and ankles of the Iron Man armor are directly welded to death, so that he cannot bend and jump, he can still move and even take off through the jet thrusters on his feet, but if the knees and ankles of Liu Feibai's black armor are fixed to make him unable to jump, then he can only stand in place obediently. It is difficult to say which of the two modes of promotion is better and stronger, but the environment in which they are applicable is different.

"Lin Chenxing, I want you to die!"

Lin Chenxing, who had already run out for a distance, heard Liu Feibai's angry shouts, and knew that this guy should not be able to catch up for a while. Otherwise, there is no need to roar so angrily.

"Huh, you want to kill me? The next time you encounter it, you can't tell who wants who's life! ”

With a cold snort, the injury was affected, and Lin Chenxing hurriedly covered his lips with his hand and forcibly held back the blood in his mouth. If he left a trace and was found by the big black dog smelling it again, then he would be dead.

Taking out the foggy swamp map he had obtained in Lishui Town from the storage space, Lin Chenxing confirmed the direction with the skills he had learned from He Nan and the others, and set off again. In this foggy swamp, there is no daylight or tall trees to be seen, and if you accidentally get the wrong direction, it will not be fun.

When Lin Chenxing was retreating strategically here, a group of people on the other side also heard Liu Feibai's angry shout.

"Haixin, that seems to be Childe's voice just now, right?"

"That's right! However, there should still be some distance, and I can't hear it clearly. ”

"Go see?"

"So what are you waiting for? Walk! ”

Immediately, a team of five people hurriedly followed the voice towards Liu Feibai's position, shouting all the way, looking all the way.

"Childe!"

"Childe, where are you?"

"Childe!"

Liu Feibai, who was stuck in the black quagmire and didn't dare to move, finally waited for his own people, and hurriedly shouted: "Here, hurry!" ”

"Childe, why are you ......" Liu Haixin, who was in the lead, followed Liu Feibai's guidance and kept searching, but suddenly stopped.

"Brother Liu, what's wrong?" The person behind saw Liu Haixin stop and asked puzzled.

"Look at the reed leaves ahead."

"Shhh

"How can Childe be in the black mire? It looks like this is still an old pit! ”

"What a word, quick, weave rope out of reeds!"

"Childe, wait a minute, we'll be here right away!" The clever ghost is very clever and didn't say, "Childe, I'll save you right away."

Liu Feibai knew that his subordinates should have discovered the black mire. Just because he hasn't been here himself doesn't mean that none of his men have been here.

"Okay, hurry up!" Liu Feibai is not in a hurry, this time, even if he didn't dare to move, he had already sunk to the shoulder position.

"Childe, wait a minute."

Soon, the two straw ropes of sufficient length were made, and Liu Haixin volunteered and said, "I'll go, you fix the rope on the side!" ”

"Yes, Brother Liu."

The two ropes were fixed on the side, Liu Haixin tied a straw rope by himself, carried the other rope head with him, and carried it into the range of the black mud swamp.

In fact, this black quagmire is not so terrible for experienced martial artists, even if it is this kind of old pit, it is big and deep, but as long as the body is not too bad, and the strength and speed are well controlled, it is no problem to walk on it in a short time, at most, it is not over the surface of the feet and calves.

Liu Feibai: It was because he was defenseless and smashed directly into the black mud from the air, and the huge impact made the black mud suddenly thin, so he fell into it and couldn't move. If his body style is not the type that uses explosive power to go straight, it is really not certain whether Lin Chenxing can walk away today.

"Childe, I'll tie it up for you!"

Carefully came to the area where Liu Feibai was, and Liu Haixin wrapped another rope around Liu Feibai's shoulder blades that were still exposed a few times and tied them tightly.

"Si'er, you pull slowly!"

"Haole, Brother Liu!"

As the rope slowly tightened, Liu Feibai slowly got out of the black mud with the force of pulling. But Liu Haixin on the side suddenly realized that something was wrong.

Slightly stunned, Liu Haixin finally found out that something was wrong, he was a little stunned and pointed to Liu Fei's snow-white robe as white as new, and stammered: "Childe, you ...... Your clothes ......"

Liu Feibai's face did not change and said, "Pull me out first!" ”

"Yes, yes, Childe!"

As Liu Feibai's whole person was pulled out of the black mud, another figure appeared under his feet, which was a black wolf.

The people in the distance didn't notice anything abnormal, but Liu Haixin, who was on the side, saw that when his son was just pulled out of the black mire, he seemed to be molting all the time, a layer of black skin, very similar to the black mire, and now the child's feet were completely submerged into the back of the black wolf, as if they were growing together.

Suddenly, Liu Haixin seemed to feel a cold wind coming from nowhere, cold to the bone, and his teeth began to chatter when it was cold.

With the joint efforts of everyone, Liu Feibai and the black wolf successfully broke away from the black mud edict, followed by a strange looking bangs.
