"This is it?" Blue River looked in the cave with some curiosity.

Fang Yan pointed to the stone wall on the side and said, "It's that this stone wall is strange, we have been attacking here for seven days without any effect, and it is still intact." ”

"Something interesting." Lan He stepped forward, looked at it carefully, and said, "This formation is indeed very powerful. ”

Fang Yan asked, "Seniors also know formations?" ”

"It's just scratching the surface." Lan He smiled: "But if you want me to crack this formation, it can only be by force." There is no other way. ”

"Can it be broken by force?" Fang Yan looked a little nervous, if this formation couldn't be broken by force, he could only go back to Ziyan to help. Naturally, it didn't matter if he asked her for help, but this waste of time made him feel a little distressed.

"There is no formation in the world that cannot be broken by force, it just depends on whether these forces can be stronger than the maximum pressure that this formation can withstand. As long as the energy is strong enough, no matter how terrifying the formation is, it will not escape the fate of rupture. Lan He said: "Your previous attack was obviously something that this formation could withstand, so there was no change in your attack for seven days. What's more, you paused in the middle. ”

"Pause?" The corners of Fang Yan's eyes jumped fiercely, "Senior, what does this mean?" ”

"This formation is extraordinary, if you want to break it, you must keep attacking in the same position, and the attack cannot be strong or weak. The same power must be maintained to attack continuously. Otherwise, if you stop in the middle of the attack, even if you attack for a few days and nights in a row, it won't have much effect. ”

"Non-stop?" Fang Yan gasped, "This formation is so strong, even if we can resist continuous attacks for seven or eight days, the vitality in our body can't support it for such a long time." ”

"Therefore, if you want to break through such a formation, you can only find more people, and the more people you have, the better. Only in this way can it be possible to attack the slope. Lan He said: "I think that the person who arranged this formation has also calculated that it is difficult for me to gather so many of them to appear here. After all, it was really just a coincidence that we had four late-stage existences at a time this time. In other words, it is a great fortune to be able to get two together. And you tried it just now, and the two of you joined forces, and it was not enough to break it. ”

Fang Yan asked cautiously, "What about ...... Senior, do you think if the four of you join forces, you will be able to break it? ”

"Just try it." Lan He took a deep breath, turned his head to Han Shan and the black-robed old man and said, "Do you decide to take a break first, start tomorrow or start now?" ”

"Listen to you." The black-robed old man said, "It's no problem to start now, we don't consume much. ”

Lan He said, "Then let's start now." Starting earlier and ending sooner, I'm already a little impatient to get back to my normal life. ”

"Let's get started." The black-robed old man didn't hesitate any longer and stood beside him.

Han Shan and Lan He also walked over, and the four of them stood in a row, their palms stretched out at the same time, and four Yuan Qi flashed out from their palms, and then met in mid-air.

"We have to gather all four forces to attack together." Lan He said: "Maximize the power of our attacks, and it may be possible to break through this formation." ”

The other three nodded, their minds moved slightly, and the four Yuan Qi were entangled in mid-air, and after a while, they went straight to the stone wall.

"Boom!"

A loud sound shook in the cave, if it weren't for the fact that the strength of the dialect was not low, I am afraid that it would be directly stunned by this sound. But even so, it was a rumbling in his mind, and it took a while to calm down.

A steady stream of vitality kept pouring out from the palms of the four people in the Blue River, gathering together and landing on the stone wall half a zhang away in front of them. Fang Yan looked at the same place for a moment, and the stone wall was still unusual, and it looked no different from before.

He frowned unconsciously, then sighed softly and turned his head to walk outside.

The strength of the four people in Blue River is much stronger than him, and the attacks released by the four late-stage existences, even if the target is not him, but the powerful pressure is not something he can resist, and the time just now has consumed nearly half of his vitality, where does he dare to continue to stay.

"Stop."

Before Fang Yan's footsteps stepped out of this stone room, Lan He's voice suddenly sounded, and then, the pressure in the stone room disappeared instantly. All four stopped attacking.

"What's wrong?" Fang Yan quickly retreated, and subconsciously looked at the stone wall, but the stone wall was no different from before.

"It's a bit of trouble." Lan He said: "If this continues, even if we can destroy this formation, I'm afraid this stone room won't be able to keep it." ”

Fang Yan was stunned: "What do you mean?" ”

"The pressure released by the four of us is too strong, and the other positions of this stone wall are not protected by formations, they can't withstand it, and they may collapse." Lan He said: "The people who arranged this formation are not simple, they have already calculated this. ”

Fang Yan's face suddenly became a little difficult to look at.

Lan He said: "However, this also tells us that with the energy of the four of us, we can break this formation. It's just that we don't know if the things behind this can be saved after destroying this formation and after this cave collapses. ”

"Is there a way?" Fang Yan asked.

"Unless there is one more person to protect this stone chamber, I'm afraid there is no way."

"One more?" The corners of Fang Yan's mouth twitched, "At this time, where can I still find people?" And this cave is too small, and the two spirit beasts outside can't enter at all. ”

Lan He spread his hands and said, "It's not impossible if you want to attack, but I can't guarantee you that the things behind this can still be used." Lan He said: "After all, we don't know what is behind this, and if it is something very fragile, it will be troublesome." ”

The dialect was silent.

Lan He didn't say anything more, and waited patiently for his reply.

"Can you set up a formation to block it?" Fang Yan asked suddenly.

"Formation?" Lan He was slightly stunned, and after thinking about it, he said: "The formation is naturally possible, but we have to see how powerful the formation is." If it's too powerful, it's useless. ”

"It should be possible to resist some of your pressure." As soon as Fang Yan's palm flipped, a wooden box appeared in his palm, "I'll arrange it first, and if it doesn't work, I'll think of other ways." ”

The four of Lan He didn't say anything, they just stood in place and watched him arrange the formation.
