This mark was very hidden and its technique was extremely strange, so that his mental power was never discovered.

In fact, when Qin Chen activated the Qinglian Demon Fire to cover his whole body, he had already noticed some weirdness. However, at that time, he focused on the dark red ghost beast, which made him not pay attention.

In addition, the mark remained on his sleeve, not on his body.

"What a cunning guy."

If the other party left the mark on him, Qin Chen would probably have discovered it long ago, but if it was left on his sleeve, Qin Chen would not burn his body with the green lotus demon fire for no reason. Instead, he would protect his clothes, so he could not find it immediately.

"Mr. Chen, what's wrong?" At this time, the black slave also looked over and said in a deep voice: "Did the other party leave a mark on us?"

He is not an idiot. Judging from the previous conversation between Liu Ze and the others, and Qin Chen's performance, he also understood that he should have been tracked down, otherwise the other party would not have been able to find him so soon.

Qin Chen nodded.

And at this time he had already figured out that the opportunity for the other party to make a mark should be when he gave the pills in Kurozuma Square.

No wonder Liu Ze took the initiative to compensate them for the pills, and the pills were not only placed in the medicine bottle, but also packaged them in a jade box.

It seems that my hands and feet should be on the jade box.

"This despicable guy, I will sooner or later know what regret means." The black slave said with a cold look on his eyes.

Then he said to Qin Chen: "Mr. Chen, since you have found the mark, you will destroy it. I should have it. In this way, I see how these two guys can track us."

"no."

Who knew that Qin Chen actually shook his head.

He looked solemn and said in a cold voice: "You can't throw away the mark now, and the most important thing now is that Liu Ze and Jiu Moxin actually know where we are going."

Qin Chen's tone was heavy.

This is what he is most worried about. With Liu Ze's cultivation level, once he passes by the underground ruins mentioned by the black slave, he may not be able to find clues.

If so, then the situation is dangerous.

Thinking of this, he hurriedly turned to look at the black slave and said in a deep voice: "Black slave, I have a task to you, but there will be some dangers."

"Your Madam Chen, you said that the black slave will definitely complete the task." The black slave was very decisive.

After so much experience, he also understood that it was too difficult to break through to the sixth-level martial master with his own experience, but it is very likely that it would be very simple to follow Qin Chen.

"good."

Qin Chen didn't say anything else. He carefully casted out a series of restrictions, stripped off the tracking marks on his sleeve, took out a jade box, and put it in.

Next, he also found out the tracking marks on the black slave, and also stripped them out with a forbidden system, and put them in the jade box.

"This is the two tracking marks that Liu Ze made before. I need you to take this jade box and quickly leave here and go in the direction of the quilt. The farther the better." Qin Chen handed the jade box to the black slave and said in a deep voice.

"Do you want me to lead Liu Ze and the others away?"

The black slave immediately knew Qin Chen’s purpose and said in confusion: “But if I leave, how could you find that underground ruin?”

"Didn't you give me a map? Moreover, you have marked the specific location on it. Although there is an extremely powerful hidden formation, with this information, it is still easy for me to find that place, not to mention that there is a spirit-seeking insect on me. The spirit-seeking insect is extremely sensitive to genius treasures. As long as you arrive at the place, you will not find the location of the forbidden area."

After the black slave surrendered to Qin Chen, the spirit-seeking insect naturally came to Qin Chen's hands.

"I understand." After thinking for a while, the black slave immediately understood that this method really worked.

The only question is whether he can escape Liu Ze and the others' tracking.

"You don't need to take this jade box and run all the time. You just need to lead them away enough distance and put the jade box on some blood beasts in the Black Death Swamp, and you can get out." Qin Chen said.

The black slave's eyes lit up instantly: "I understand."

Just like the previous mud dragon, he just threw the jade box into the mud dragon's mouth, and Liu Ze and the others would naturally be able to track the whereabouts of the mud dragon, and he would be able to escape smoothly.

After discussing the plan, Qin Chen injected a force of the green lotus demon fire into the black slave's body.

"The most dangerous thing in this black death swamp is the ghost beast. You have the Demon Banner and the power of the green lotus demon fire that I injected into your body. Even if you encounter the ghost beast, there will be no danger. Once you throw away Liu Ze and the others, you can find a place to hide. After I get Ku Yunzhi, I will come to you as soon as possible."

"Hehe, Mr. Chen, don't worry. This place is very close to the underground ruins I discovered. Lao Hei, I have been here a few years ago and have been exploring for a long time. I am very familiar with the terrain here. It is not so easy for Liu Ze to catch me. Since that's the case, Mr. Chen, I will leave first."

After the black slave finished speaking, he immediately came out of the hidden formation and flew quickly towards another direction, and his figure quickly disappeared.

It was hundreds of miles away.

"Um?"

Liu Ze, who was heading southeast, suddenly stopped.

"President Liu, what's wrong?" Jiu Moxin also stopped in shock.

Liu Ze frowned, looked at the disc in his hand, and said in confusion: "The tracking marks on those two guys can sense them again."

"This..." Jiu Moxin was stunned: "What should we do?"

Liu Ze thought for a moment and said in a deep voice: "The location of the tracking mark is near before. It should be that the two of them entered a strange place, or some reason, which caused the instrument to not detect the tracking mark. Later, after leaving that place, the signal appeared again."

"But what's strange is that this time they didn't come southeast, but went northeast."

Jiu Moxin suspiciously: "Can they discovered the tracking mark?"

"It's impossible." Liu Ze shook his head and said confidently: "My tracking mark, even the sixth-level martial master, may not be able to detect it. How could the two fifth-level martial masters discover it? It should be an accident."

Speaking of this, Liu Ze grinned: "Let's go, let's go there immediately. Let's let them escape before, this time, they will not be so lucky."

After the words came, Liu Ze and Jiu Moxin changed directions and quickly flew towards the location of the moving tracking mark.

Qin Chen waited for a while in the concealing formation before putting it away and rushing towards the east.

Half an hour later, Qin Chen had arrived near the location marked by the black slave on the map.

“It’s near here.”

After putting away the map, Qin Chen flew for a moment, a lake suddenly appeared in front of him. It was said to be a lake, but it was actually just a larger water sieve.

"It's here."
