Liu Yilin yelled and hurriedly leaned against Ning Beichen in fear.
If water is Luo Yingying's weakness, then snakes are Liu Yilin's nemesis. As soon as she sees a snake, she will feel weak all over.
"You are the snake, your whole family is a snake, and I am the dragon."
The head stuck out said angrily.
This thing is quite vindictive, and it has learned and applied what Ning Beichen scolded it before.
"Dragon? This thing is a dragon. It's so ugly!"
After hearing that it was not a snake, Liu Yilin was not so scared anymore.
"roar!"
Although the black dragon is a dragon, it became angry when it heard that he was ugly. Different species, in the eyes of the black dragon, humans are the ugly creatures.
A roar of a dragon!
Suddenly, the surroundings were filled with wind and clouds, and black mist spread, instantly trapping Ning Beichen and the others.
"There is something strange about this black mist. Don't separate, everyone should come closer to me."
Ning Beichen and Luo Yingying shouted at the same time.
Liu Yilin and Ye Lanxin immediately leaned towards Ning Beichen, and the four of them leaned together. However, the black mist around them filled up quickly. No matter how they retreated, they could not leave the scope of the black mist.
"Damn it, it's the black dragon. It must have been caused by the black dragon."
Luo Yingying shouted angrily.
She had been tricked by the black dragon before, so she was very angry with it.
"No, we are trapped in the black fog, and...and I feel like something is wrong with my body."
Ye Lanxin said with fear.
"Me too."
Liu Yilin and Luo Yingying spoke at the same time.
"Is it poisonous?"
Ning Beichen himself didn't feel anything was wrong, but Luo Yingying, Liu Yilin and Ye Lanxin all felt something was wrong, so there must be something wrong.
"But if it's poison, then why is he fine?"
Ning Beichen couldn't figure it out. Could it be that this poison only targets women?
"Get out!"
Ning Beichen slashed at the black mist with his sword. Since he did not join forces with Luo Yingying, what appeared was a black sword light.
The sword light that was a hundred feet long missed in the black mist, but it did not hit the black dragon and disappeared into the black mist.
"Come out, get out of here, you ugly thing!"
Ning Beichen shouted loudly and kept swinging his sword at the black mist.
"Hahaha, it's useless, human. You are no match for me here. The black mist is filled with poison."
The voice of the black dragon came from the black mist.
"Hmph! Don't scare me. I know you are trapped under that black river and can't get out at all. Otherwise, you would have come out and killed us long ago."
Ning Beichen said coldly.
"So what? I can't come out and kill you, but I can control the black mist so that you can never leave this place!"
After a while, the sound of the black dragon came.
"Black Jiao, we have not offended you, we just want to pass through this place. Why are you targeting us? Calculating that you want to use us as food, our size is probably not enough for you to stuff between your teeth. Do you find it interesting?"
Ning Beichen said.
This time the black dragon did not respond, and Ning Beichen was extremely worried when he saw Luo Yingying and the others seemed to be in pain, and their bodies were very hot.
He tried giving them detoxifying pills and using his own internal power to force the poison out of them, but to no avail.
Ning Beichen cares more about them than himself.
"Okay, Black Dragon, you win, what do you want to do?"
Ning Beichen stood up and said loudly to the black mist.
"I want you to do something for me. As long as you help me, I will not only let you go, but I will also drive you directly to the exit."
After a while, the sound of the black dragon came from the black mist.
"No, Ning Beichen, this black dragon clearly has bad intentions."
At this time, Liu Yilin and the others spoke in unison.
"What happened?"
Ning Beichen ignored them and asked Heijiao if it was not something difficult to accomplish, Ning Beichen would be willing to do it for the safety of Liu Yilin and the others.
"It's very simple. There is a formation under the Black River. There are eight chains in the formation. You only need to enter the formation and cut off these eight chains."
The voice of the black dragon came.
"If I'm not wrong, these eight chains are what trap you, right? How do I know that you won't go back on your promise after I cut off the chains?"
Ning Beichen said calmly.
"There is no way, you can only believe me. It is true that as you said, you have no ill intentions towards me. Even if you serve me as food, it is not enough for me to eat, so I can't find any reason to deal with you.
.”
Black Dragon said.
"Ning Beichen, don't trust it. Once it gets out of trouble, we won't be able to do anything if it goes back on its word."
Luo Yingying said.
"I know, but I can't let it hurt you. I know what to do, so don't worry."
Ning Beichen sent a message to the three of them.
For Ning Beichen, if he could save them by taking a gamble, he would definitely take the gamble.
But Ning Beichen is not easy to deceive or bully.
"I can promise you, but you have to swear with your soul that you will not embarrass us after you get out of trouble, otherwise the sky will strike with thunder and you will die without a burial place."
Ning Beichen said to Heiwu.
The eyelids of the black dragon hiding in the black mist twitched several times. This human boy was too sinister. In fact, Luo Yingying and the others' worries were not unreasonable.
The black dragon really thought about killing the four of them after escaping from the trap.
But now Ning Beichen made him swear a poisonous oath to help him, which made Black Dragon's plan come to nothing.
For cultivating or non-human cultivating creatures like them, if you swear a poisonous oath with your soul, you must keep your promise, otherwise, the poisonous oath made will definitely come true.
For the black dragon, there is no need to consider whether to kill them to vent its anger or to escape from the trap. It has been trapped in the abyss of the ancient road for countless years, and it desperately longs for freedom.
So compared to freedom, Black Dragon doesn't need to make a choice at all.
"I, the black dragon, swear to the sky here that once I get out of trouble, I will never make things difficult for you four, and I promise to send you safely out of the ancient road. If you violate the oath, I will strike five thunders from the sky and die without a burial place!"
Not long after, the voice of the black dragon came from the black mist.
"No, I have to see you swear with my own eyes. Otherwise, how do I know you didn't lie to us?"
Ning Beichen said dissatisfied.
"Okay, I promise you."
Although the black dragon is angry, it has no choice. In order to be free, it can agree to any conditions, but the premise is that this human being can really get it out of trouble.
Soon the black mist surged, and not long after, a huge dragon head appeared in front of them.
"I, the black dragon, swear to God..."
Black Jiao renewed the oath he had just made with his own soul in front of Ning Beichen.
