"This is Poison Flame Ivy. ”

Zhang Ning looked at the city wall covered with vines, and said in a solemn tone: "I heard that anyone who is locked up in the Ice Purgatory will be poisoned by the cold poison once their skin is cut by the thorns on this vine. ”

These Liu Yifan has also heard that the effect of the poison will also change according to the length of time that person stays in the ice purgatory, the longer the time, the more powerful it is, it is said that people who have been in the prison for more than eighteen days, once they come into contact with this poison, it can instantly freeze people into ice cubes!

This poison ivy not only prevents the people inside from escaping, but also has a great impact on those who want to enter before climbing the wall.

It's not just the dense thorns that make it impossible for people to get their feet, once they are carelessly cut through the wound, as soon as they enter the ice purgatory, they will have a fire poison attack.

In the extreme cold of the Ice Purgatory, if you don't use internal force to suppress it, the fire poison will soon spread throughout the body, and finally the blood in the body will evaporate and die.

Even if internal force is used, the longer it stays inside, the more internal force needs to be consumed to suppress it, which means that the strength that a person can exert is constantly being reduced from the moment he steps into the Ice Purgatory.

Although this reduction will stop when you get out of the Ice Purgatory, your strength will not be restored immediately, and the fire poison in your body will take time to dissolve.

At this time, if you encounter the guards outside the Ice Purgatory, there is no time to resolve it under the scuffle, and with the continuous consumption of internal force in the battle, it will only lead to the fire poison in the body that cannot be suppressed, either the fire poison will burn you to death, or you will be captured.

It can be said that this arrangement of Ice Hell City makes it impossible for the people in the Ice Purgatory to get out, and it is useless for the people outside to enter, and it is an excellent place to be imprisoned.

Although the other sects also have their own places to detain people, they are too simple to even put on the table, so for those who still have use value and are worried that they will be rescued, each sect finally chooses to lock people up in Ice Hell City.

This makes Ice Hell City have a connection with many sects, which is why it has only been established for ten years, and it has become famous among the ranks of famous sects, in addition to the strength it has, this Ice Purgatory is also the most critical point.

Liu Yifan looked at the poisonous vine, he was not afraid of this kind of thing, but what about Cai Yan?

How many days she has been imprisoned in it Liu Yifan is still uncertain, but I think it will not be less than nine days.

This kind of fire poison and cold poison should be easy to get rid of in normal times, but there is no grass and no medicine around him now, and he doesn't know what to bring in.

It means that within less than nine days, when he rescued Cai Yan from the ice purgatory, he could choose to climb the wall to leave, and if he had been looking for nine days, he could only bring people out through the gate of the inner city!

The difficulty of the former is not clear for the time being, and the way the latter takes people away from the city gate, unless Wei Zhongdao can cooperate, otherwise it is impossible.

"Let's go, let's go up and have a look. Liu Yifan threw Zhang Ning two thick cloths and motioned for the other party to wrap them in his hands.

As for the scratched body, it doesn't matter, anyway, they are not going to enter the ice purgatory today, they are just here to investigate, as long as the fire poison is not stimulated by the cold, it can be easily dissolved when they return to the inn.

Zhang Ning also knew this, as soon as he took the cloth and wrapped it, he saw a black shadow flashing in the distance out of the corner of his eye, and hurriedly said, "It seems to be someone!"

When Liu Yifan heard this, he hurriedly followed Zhang Ning and the two of them hid behind a low wall nearby.

After a while, two men appeared, also dressed in masked night clothes, one of them carrying a bow and the other holding a spear.

The two of them went from far to near, without stopping at all, and climbed directly towards the city wall full of poisonous vines.

As for whether the two of them were going to save people, or whether they were here to investigate first like the two of them, or if they were doing something else, I don't know, Liu Yifan and Zhang Ning, who saw this scene behind the low wall, turned around and left here in unison.

The two thought of changing directions, lest the two of them make any noise, and it would be bad if they were still involved.

Dodging the two teams of Seven Holy Sect patrol disciples, Liu Yifan and Zhang Ning came to the city wall on the other side, and before the two of them could think about climbing up, they heard an extremely subtle "hiss".

When I looked up, I vaguely found that there seemed to be a figure climbing up on it, probably because I was accidentally stabbed by the thorn of the poisonous vine just now, and this is the sound.

Liu Yifan and Zhang Ning were helpless, they could only think of climbing in other places, and as soon as they quietly approached the city wall, they saw a black shadow not far away doing the same thing.

When Liu Yifan found the other party, the other party also noticed them, but when he saw that the two of them were also wearing night clothes, the original guard was lifted a little, and he climbed the wall by himself without paying much attention to the two of them.

Looking at that reaction, it is probably not the first time that I have seen someone who is dressed the same as him and has the same purpose.

“...... There are so many people in the middle of the night. Liu Yifan didn't know what to say.

glanced at Zhang Ning and found that the other party was also looking at him, and the surprise and astonishment in his eyes were no less than his.

Both of them are thinking about how to rescue people who are important to them, and now it seems that Liu Yifan and Zhang Ning are not the only ones who want to save people.

changed another place, this time no one else was found, Liu Yifan and Zhang Ning began to climb up, just to avoid being scratched and stabbed by the stinger, lest the smell of blood be smelled and exposed, and the speed of the two of them couldn't get up.

I don't know how long it took, but the two of them finally climbed to the top of the city wall with a lot of thorns in their clothes, hid behind the battlements and looked inside.

After observing the route patrolled by the disciples of the Seven Saints Sect on the city wall for a while, and after finding a flaw, the two of them hurriedly reflexively entered, silently running from that flaw to the other side of the city wall.

They had barely run halfway when a dark shadow suddenly flipped over from outside the other side of the city wall and ran in their direction.

It may be that the person just paid attention to the disciples of the Seven Holy Sect around him, and when he found that there were two more people in front of him, his body suddenly froze somewhere.

Liu Yifan and Zhang Ning were also frightened by each other's sudden appearance, but looking at each other's night clothes, they immediately guessed that this person was probably going to investigate, and he was going to go back, right?

The man was also obviously relieved after seeing that he was not a disciple of the Seven Holy Sect, and continued to run over without stopping, but when he passed by the two of them, the man put his hands on the two halberds on his waist, looking guarded.
