Lin Qinghe said: "This is a cave, there is nothing in it, but I saw a raised button on one wall. ”

Lin Zilu nodded slightly, "Press it and try it." ”

"Hmm."

Lin Qinghe pressed it lightly, and he heard the sound of zaza, and a hole door was exposed on the stone wall.

A halo shot out of it, and the man inside walked in and closed the door.

This is a secret room with bright light, there is nothing in the secret room, it is also empty, Lin Qinghe walked around it and said, "There seems to be nothing here." ”

Lin Zilu said: "Don't you notice, is there any difference here?" ”

"Different?"

"Hmm."

"Nope."

Lin Qinghe answered very truthfully, she really didn't notice any difference between here and outside.

Lin Zilu said: "I can feel that time passes much faster here than outside. ”

"Huh?" Lin Qinghe couldn't help but look around, "I didn't find anything wrong." ”

Lin Zilu said: "Ten years here, maybe only one year outside." Perhaps, it is a year here, and only one day outside. ”

Lin Qinghe blinked, "Really? ”

"Of course."

"That's really good, let's practice here for ten or eight years, and it's only been a few days outside."

Lin Qinghe said happily, if this is the case, if he practices well here, his internal strength will definitely grow rapidly, so why worry about those who don't return to the Sword Sect?

Lin Zilu said: "Am I worried about the people who don't return to the Sword Sect? ”

Lin Qinghe nodded, "However, if we get out of here, we don't have to worry about it anymore." ”

Now the gap between Lin Zilu and them is not big, and if you stay here for a while and practice diligently, you will definitely surpass them.

Lin Zilu said: "Yes, we can take advantage of this time to practice more here, and when we go out, maybe it will be a long time later." ”

The two of them said to do it, and immediately practiced here, if they were hungry, it didn't matter, they could take the pills, although there were not many pills on Lin Qinghe's body, but there were a lot of pills in Lin Zilu, and the pills in his ruins were enough for them to eat here for a hundred years.

And it's only ten days out there at most.

In this way, Lin Zilu is still very confident in defeating those old guys outside.

After staying here like this for a few days, they relied on taking pills to replenish their physical strength every day, and time passed day by day, but neither of them noticed it, and they kept practicing every day.

This is the best place to retreat, it is extremely difficult for outsiders to enter, and those guys who do not return to the Sword Sect must still be guarding outside.

Lin Zilu had been in retreat before, so with a little guidance to Lin Qinghe, Lin Qinghe also understood the essentials of the retreat.

The two of them have been practicing here for almost a full ten years, ten years, and only a few days outside.

And the two of them did not feel the passage of time at all, and generally speaking, people who were immersed in retreat would not be aware of it at all, and ten years was just a snap of a finger for them.

Lin Zilu asked: "Rushuang, you ......"

"Zilu, I like it when you call me He'er."

"He'er?" Lin Zilu was slightly stunned.
