"Yes, the main danger is the Raging Rats, you are not here at the right time, these days of the year are the mating time of the Raging Mouses. ”

"What is the mating period?" Zhang Yu asked puzzledly, although Elder Liu gave some comprehensive information about the spirit stone cave, he did not write about the mating period of the berserk rats.

"There was once an alchemist who went to catch more than a dozen rats to study in order to study rampaging rats. There were more than a dozen outer disciples around him, and he knew that less than ten minutes after catching the rats, he saw the gray tide, and none of the people in the group ran away, they all died. In the end, someone specially investigated this matter and found that it was the mating period of rampaging rats, and the speed and strength of the rats at this time were greatly increased, and many times everyone avoided messing with rats at this time. Wang Lao said with palpitations.

"I see!" Zhang Yu nodded.

The two chatted for a while about the situation in the Black Iron Castle, and suddenly saw a little white light in the distance.

"Alright, we're almost past the barrier. Wang Lao said with a smile on his face.

At this moment, Zhang Yu suddenly remembered Lin Xueyue's voice in her mind, and she said, "We overheard someone talking about it just now, and things are in trouble!"

"I'm a little dizzy, I'll go down and rest for a while. Zhang Yu made a reason, said goodbye to Wang Laoman, and came to the cabin.

The cabin was full of goods, Zhou Fat'er was lying in the hammock and falling asleep, while Feng Chengyue was practicing the iron cloth shirt next to him, and hurriedly greeted Zhang Yu when he saw him come down.

"You keep practicing, I just drank some wine and go lie down for a while. Zhang Yu said with a smile, he lay down in the hammock and closed his eyes and pretended to sleep, but he was asking Lin Xueyue what happened to them.

"We were curious to look at each of the boats, and we heard your name mentioned, so we looked at them curiously, knowing that they were going to kill us on the first day. Lin Xueyue slowly narrated.

"A line of heaven?" Zhang Yu frowned, he recalled the map in the data, and finally remembered the information of the first line of heaven, the first line of heaven is very close to the Black Iron Castle, about a hundred miles away, and the cultivators of the foundation building period will arrive in a few moments at most.

It is as if the earth has been split by a knife, and the cliffs on both sides are towering, and the middle is very narrow, and the narrowest part of the distance is only ten meters.

There are many crevices and caves on both sides of the cliff, which makes Zhang Yu have to think that if he encounters a gray tide, he will really die.

"What else did they say?"

"No, do you want me to find a way?" Xiao Hei stuck his head out next to him and said with a sinister smile.

"No, don't mess around here, you can spy on them to see who they come into contact with, maybe you can find out something. Zhang Yu was silent for a moment and said.

"Look at me. Xiao Hei estimated that he was too bored, and disappeared into the air with excitement.

At this moment, it was getting brighter and brighter outside, Zhang Yu opened his eyes and walked up to the deck curiously with Feng Chengyue, and unexpectedly found that this was Xintiandi.

The tunnel has shrunk a lot, and countless fluorescent stones are installed on the tunnel walls, like a galaxy, shining with a faint light, illuminating the surroundings.

"Hehe, you see that there is Lantian Transit Station in front. Wang Laoman walked out and pointed ahead.

As soon as Zhang Yu and the others looked, a huge city appeared in front of them, the entire underground was hollowed out, and countless floating boats were floating in mid-air, transporting supplies in and out.

The fleet soon docked in the city, and Zhang Yu and the other outer disciples who had just come here were all gathered, and each of them distributed a jade slip, which recorded the situation of the spirit stone mine.

After Zhang Yu absorbed the contents of the jade slip, he silently supplemented the complete information, according to the notice above, they will be repaired here for a few days, and everyone will go to the assigned post.

"They're coming......" At this moment, Zhang Yu heard Xiao Hei's voice in his ears, he turned his head to look, and saw several outer disciples of the sixth layer of qi refining walking towards this side, one of them was a little familiar, but when he was fighting with Liu Qingfeng, that person followed behind, could it be that this group of people was Liu Qingfeng's people?

"Isn't this Zhang Yu, the first place in the selection competition?hahaha, you actually won Liu Qingfeng, it's very awesome!" said a short disciple with his arms crossed and laughed.

"What's awesome, the third layer of qi refining, actually mixed with the black iron castle, I think it can live for a week at most." Another tall disciple said triumphantly.

"You ......" Feng Chengyue and Zhou Fat'er were furious, and just wanted to speak, but were stopped by Zhang Yu.

"You don't need to take care of these things, as far as I know, even the death rate of the sixth layer of qi refining is the ninth layer. Zhang Yu said lightly.

"Paralyzed, you ......" The big disciple was furious when he heard this, and he just wanted to make a move, but was stopped by his companion.

"Don't be like him, we still have important things to do......" The short disciple said as if he were looking at Zhang Yu and the others as if they were dead. The tall man suddenly realized, spat on the ground with a disgusted expression, and the group turned away.

"Keep up,......" Zhang Yu said coldly, and Xiao Hei disappeared into mid-air in an instant.

"Boss, they're bullies. Zhou Fat'er said angrily.

"If I have the strength of the sixth layer of qi refining, I am guaranteed to beat them. Feng Chengyue gritted his teeth and said.

"Okay, I promise they'll be taught a lesson, let's go get the equipment first!" Zhang Yu said with the corners of his mouth slightly upturned. Perhaps believing in Zhang Yu's judgment, the two of them didn't continue to mumble, and followed Zhang Yu to get the equipment.

Every disciple who arrives here will have standard equipment, and only inner disciples have the right to configure their own equipment.

When they came to the quartermaster camp, they saw many outer disciples lining up to receive equipment, and they also hurriedly lined up behind.

After about ten minutes, a set of leather armor, a long knife and a shield were handed out to them, in addition to this, there was also a backpack containing some elixirs and equipment to stop bleeding.

The long knife is carved with a sharp formation, the shield has a solid formation, the long knife can instantly split the body of a rampaging mouse, and the shield can also resist bites. And the leather armor inlaid with the defensive formation and the light formation can protect the body from damage.

"This set of equipment is worth at least 20 intermediate spirit stones, and the sect is really generous. The fat man excitedly turned over and over the equipment, and kept stroking it with his fat hands.

"Of course you're generous, you're selling your life!" Feng Chengyue said angrily.

"Okay, let's familiarize ourselves with the equipment first, and don't rush around when the time comes. Zhang Yu said with a smile, and they returned to the temporarily arranged dormitory, and then put on the equipment.

"Do you think I'm handsome?" said the fat man proudly.

"Handsome, handsome cricket!" Zhang Yu said with a smile, the fat man became proud for a while, and only after half a ring did he realize that something was wrong.

I had dinner at noon, and in the afternoon, Zhou Fat'er was called away by the medical team, saying that he had to learn medical skills and had to be trained, but in fact, these trainings were for outer disciples.

It is enough to treat minor injuries and illnesses directly, and it can also save resources.

Feng Chengyue also went to the training ground to practice the iron cloth shirt, and Zhang Yu stayed in the dormitory, because Xiao Hei had new news.
