"What's wrong?" Seeing his appearance, Luo Ziyi and Liu Yinyin, who had just relaxed, also became nervous inexplicably.

Fang Yan's lips moved, but he didn't know what to say, and he was very anxious.

"I really got it right with his crow's mouth." Ziling shook his head a little helplessly, and said bitterly: "There is really danger here. ”

"What danger?" Luo Ziyi and Liu Yinyin said nervously: "There won't really be pressure, right?" ”

"It's more dangerous than stress." Ziling smiled bitterly and said, "Oxygen." ”

"Oxygen?" Liu Yinyin was stunned for a moment and asked, "What do you mean?" Not enough oxygen here? ”

Ziling said: "If you feel it carefully, you will know that the oxygen here is slowly decreasing. ”

Luo Ziyi and Liu Yinyin's faces suddenly turned a little blue, neither of them expected that they had just escaped from the tiger's den and entered the wolf's den again.

"Don't worry, these pressures are not decreasing quickly, we have a lot of time." Fang Yan let out a long breath, where can he take care of so much, and directly searched along the surrounding rock walls.

"Hey, aren't you afraid of being stressed now?" Ziling asked.

"There is so much management now, even if there is no pressure, we can't hold on for too long." Fang Yan carefully searched the surrounding rock walls, "There are so many people now, and in two hours at most the oxygen here will be exhausted." ”

"Two hours?" The corners of Ziling's mouth twitched slightly, "Isn't it too exaggerated?" ”

"There's only going to be less and not more."

Ziling slapped his forehead and got up to look around.

Liu Yinyin and Luo Ziyi didn't dare to sit anymore, and stood up one after another.

The four of them were on one side of the rock wall, and no one spoke again, and even the little demon phoenix could sense that the atmosphere in this cave was a little solemn.

However, time passed slowly, and half an hour passed, and they searched almost the entire rock wall, but they found nothing. Not to mention any mechanism, not even a single obvious trace was found.

"It's not going to be a dead end, is it?" Ziling suddenly thought of something, and exclaimed, "The owner of this forbidden land didn't just deliberately lure us here and kill us, right?" ”

"If he really wants to kill us, he will have the opportunity at any time, and he won't have to work so hard." Fang Yan glared at her and said, "Think about it, if we don't come in here, if we are still outside now, what will happen now?" If we were still out now, everyone would have to face at least six or seven spirit beasts, do you think you can hold on? ”

Ziling stuck out his tongue and wondered, "Then why is there nothing here?" ”

Fang Yan rolled his eyes: "If it is so easy for us to find out, he doesn't have to trap us here, wouldn't it be easier to just let us out?" ”

"So what now?" Ziling sat down directly on the ground, looking like he didn't plan to waste any more time on this rock wall.

"How do I know?" Fang Yan swept his gaze back on the rock wall, walked to the rock wall behind Zi Ling and continued to search, "Let's find it first, and then talk about it when Zi Yan wakes up, if it really doesn't work, let's attack it hard." ”

"Whew! Bang! ”

As soon as he finished speaking, a loud noise rang out from the side, startling him.

The sound came from the rock wall he had just left, but when he looked back, he saw nothing.

"Huh?" Ziling let out a soft sound, and his palm moved again, and two more rays of vitality fell heavily on the rock wall.

"What are you doing?" The tongues were shocked.

"Didn't you say you couldn't do it and attack hard?" Ziling looked at him innocently, "I'll try to see if the hard attack works." ”

Fang Yan was shocked and angry, seeing that her attack did not bring any serious consequences, but he didn't bother to say anything more, and walked towards the rock wall, asking, "How much force did your attack use?" ”

"I didn't dare to push too hard, maybe four or fifty percent." Ziling replied.

The rock wall is as smooth as before, where can I see any signs of attack?

Fang Yan struggled for a moment, and finally stretched out his palm and slammed it towards the rock wall.

"Bang!"

After a loud bang, he opened his mouth wide and withdrew his fist with a strange expression.

"Hahahaha......" Ziling laughed, unable to squeak.

"Are you alright?" Liu Yinyin looked at him with amusement.

Fang Yan waved his hand, and after a while, he pulled out the cold air and said, "This rock wall is too hard, right?" Not only was it okay to punch down, but it almost broke my hand. ”

"I don't have the vitality to help it, you dare to reach out directly, it's really stupid." Ziling was merciless and sarcastic.

Fang Yan ignored her and stood aside thoughtfully.

"What are you thinking?" Ziling asked.

"Remember when you were outside?" Fang Yan said: "When we were outside, if it weren't for the fact that you were unwilling to keep fighting against that energy shield, we wouldn't have discovered the entrance to that formation so quickly. If we find that entrance any later, we'll probably not be able to get here. ”

Ziling was confused: "So what? What do you want to say? ”

"I'm wondering if this place is the same as the energy shield outside, and it needs to be attacked consistently." Fang Yan said: "If this is the case, if we don't attack now, it may be too late later." ”

"Do you want to attack or not?" Ziling asked impatiently.

The dialect didn't speak, and sent an attack directly at each of the other three rock walls.

"Bang bang bang!"

Three attacks landed on the rock wall, leaving no trace.

The dialect immediately decided: "One person attack a rock wall and see if he can find something." ”

"If we continue to attack like this, will this cave collapse?" Liu Yinyin asked in a low voice.

Fang Yan smiled bitterly: "If it collapses or there is still a glimmer of life, if we continue to do it like this, it will be a dead end." ”

"Then let's do it." Without saying a word, Ziling launched an attack towards the nearby energy shield, and the power of the attack was slowly increasing, but even if she landed on this rock wall with all her strength, the rock wall did not leave any traces.

"It's kind of weird." Ziling muttered, but the attack in his hand was much faster.

After sending out a few attacks to no avail, Fang Yan hesitated for a while and directly took out the divine weapon. Then gritted his teeth and flicked towards the rock wall in front of him.

"Whew!"

The majestic vitality fell on the rock wall in the blink of an eye, and a sound that almost pierced everyone's eardrums sounded in the cave, but the rock wall was still unscathed.

"Choke, choke!"

The vitality energy reflected back by the rock wall flew down in all directions, almost seriously injuring Luo Ziyi and Liu Yinyin, but fortunately, Ziling quickly protected them behind him.
