"How many keys do you think there will be?" Liu Yifan looked at the Seven Holy Sect disciples patrolling and guarding below for a while, and asked casually.

Zhang Ning was also carefully observing the guards, looking for a gap that he could sneak into, and when he heard Liu Yifan ask, he hesitated for a moment and said, "There are nine." ”

Liu Yifan frowned slightly when he heard this, this answer was not what he expected, but what was the conviction in Zhang Ning's tone, did the other party know?

"How can you be sure that there are nine?" Liu Yifan wondered.

"I came to my father once before, and my father was not worried about the person who wanted to be locked up here, so he said that he would personally send him to the Ice Purgatory. ”

"This was originally not in accordance with the rules, but the city lord of Yuan saw that my father personally spoke, so he did not refuse. When Lord Yuan took the key, his movements were very hidden, and I just accidentally saw that he took one from a bunch of keys. ”

"I don't see the number, I can only be sure that it must be more than just one. As you can see, there are nine doors in this Ice Purgatory, so of course there will be nine. ”

"Could it just be that it's just with the other keys? Actually, there is only one door to open the door?" asked Liu Yifan.

In the past, when the house was still open with a key, there was everything from car keys to various doors in the house.

"In such an important place as Ice Purgatory, the key must be kept alone. Besides, as the city lord here, I don't think he needs to carry any other keys besides the Ice Purgatory, right?"

“...... Also. Liu Yifan also knew this possibility, and he confirmed it just now, but he still hoped in his heart that what Zhang Ning said was wrong, and how good it was to have only one key.

But before Liu Yifan was ready to accept that there should be nine keys, Zhang Ning's words surprised him again.

"Actually...... Strictly speaking, I think there will be eighteen keys to open the door. At that time, only half of the key that City Lord Yuan took out was in the hands of the person who took us to the Ice Purgatory. Only two keys together can open that door. ”

“......”

Liu Yifan didn't know what to say, he was thinking about stealing the key to save people, although it was difficult, it was not impossible, but now it seems that he is a little naïve.

If the keys all look very similar, you need to know a specific code to tell which one opens which door...... Wouldn't he have to steal them all?

This was already difficult enough, but now the keys had to be combined in pairs to be used, and once they were kept separately, he could collect them all if he wanted to......

Liu Yifan only felt that his head was bigger.

No wonder Zhang Ning was so positive when she heard about Wei Zhongdao's affairs, she already knew this, probably because she wanted to spy on the situation of those keys through Wei Zhongdao.

If only they could find out what doors those keys could open, they would be able to steal them with a purpose, instead of being as ignorant as they are now.

As for who holds the key, it is not difficult to estimate that it must be four of the nine Dharma protectors of the Seven Holy Sects guarding here.

Liu Yifan looked at the four big tents that were a hundred steps away from the nine-story pagoda, located in the east, west, north and south directions, which were much larger than the four in other tents.

"Liu Gongzi, have you found out?" Zhang Ning suddenly asked.

Liu Yifan knew what the other party was asking, and he just saw that he was about to tell Zhang Ning, but the other party spoke first: "I guess they used to wander around outside the plug, and this kind of guarding in one place is not suitable for them." ”

Zhang Ning nodded, she actually thought the same way, after observing for a long time just now, she found that although there were many disciples of the Seven Holy Sect patrolling, they were all loose, and from time to time they would deviate from the best patrol route, making a lot of gaps and blind spots.

As long as they could avoid the area illuminated by those bonfires and ensure that they were not discovered by the disciples of the Seven Holy Sect guarding the city walls, it would not be too difficult to sneak into those four tents.

Liu Yifan and Zhang Ning glanced at each other, and the two began to crawl down in unison, they wanted to confirm whether the four tents were just a trick, or if they were really the places where the four Dharma protectors lived.

If the four Dharma Protectors are indeed there, then the key is not on the other side, and each person is holding a few of them, all of which need to be known.

Wei Zhongdao hasn't come yet, even if he comes, it's still difficult to say whether he can rely on the other party, in these are unknown situations, many things still need to be confirmed by his own eyes, and he can be prepared for all kinds of possibilities.

It's one thing to see the loopholes between these patrols before, but it's another thing to actually want to get through them undetected.

The speed of the two sneaking was not fast, and it took a short time to stop and go before finally touching the vicinity of a camp.

Zhang Ning was looking around, Liu Yifan cut a gap with a knife, looked inside, and by the faint candlelight in the tent, he didn't see a person.

signaled to Zhang Ning that there was no one here, let's change another one, and the two began to sneak towards another camp.

The Seven Saint Sect disciples who had avoided several patrols, and as soon as the two of them approached the tent, they saw two black shadows silently flashing from the back of the tent.

One with a gun and one with a bow on his back and both dressed in night clothes, these two Liu Yifan and Zhang Ning have also seen each other, they are the two people they saw behind the low wall earlier, but they didn't expect to meet here again.

The two people on the opposite side didn't know that they had been seen before, and when they saw someone suddenly appearing at this moment, they were shocked and subconsciously raised their guns and bows, preparing for a battle.

When he saw Liu Yifan, Zhang Ning and the two of them in the same outfit, he also thought of something, the man with the gun didn't speak, but just left with the man with the bow as soon as he gave his hand.

I didn't care too much about the distance before, but at this moment, at close range, Liu Yifan and Zhang Ning could see that it was a man who used a gun and a woman who used a bow.

Watching the two of them leave, especially the woman with the bow who had been looking at this place with a vigilant gaze before walking away, Liu Yifan Jue's person looked a little familiar.

"With a bow, it's still a woman...... Could it be Sun Shangxiang?" Liu Yifan flashed this thought,

He and the other party have been sharing the same bed for several days, although it is only pretended, but it is not close contact, and many details that cannot be observed at a distance will be noticed.

Especially that vigilant look, he has seen it many times, he shouldn't be wrong!
