"Sister Shuang, let's go, let's go up. Along the way, see if there is anything different around you. Chen Kai looked up at the mountain peak, and said to Luo Shuang.

Luo Shuang retracted his gaze and looked at Chen Kai beside him, and couldn't help but nodded, "Hmm." Know. ”

Then the two of them began to climb the mountain together, and in the process of climbing, the two of them had been paying attention to the surrounding qiqi, and Chen Kai had already stimulated his spiritual sense and directly probed into the mountain to investigate.

However, his spiritual sense could only cover a radius of thirty meters around him. If his spiritual sense could directly envelop the entire mountain, it would be simple, where there was anything unusual, he could directly sweep it with his spiritual sense, why did he need to look for it slowly like now.

More than two hours later, Chen Kai and Luo Shuang had already reached the top of the mountain, but they still didn't find anything. Chen Kai was not discouraged, he and Luo Shuang rested a little on the top of the mountain, ate something, and then continued to look for the other side of the mountain.

After more than half an hour, Chen Kai was suddenly stunned, and then turned his head sharply to look at a very steep rock wall on the right. His brow furrowed, and he walked straight towards the rock wall.

Seeing this, Luo Shuang next to him immediately looked at Chen Kai with a puzzled look, hurriedly followed, and asked, "Chen Kai, what's wrong?" Got a discovery? ”

Chen Kai didn't look back, just raised his hand and waved at Luo Shuang, signaling her not to disturb herself first. Immediately afterwards, Chen Kai walked to the rock wall and stretched out his hand to stroke it carefully.

After a while, Chen Kai took two steps back, looked up at the steep rock wall, and then turned his head to Luo Shuang, who was looking at him next to him, and said, "Sister Shuang, you step aside first." ”

Although Luo Shuang didn't know why Chen Kai told her to retreat, she still responded without the slightest hesitation: "Oh, okay." Then he immediately stepped back to the side, looking at Chen Kai with curiosity.

Seeing that Luo Shuang had retreated, Chen Kai refocused his gaze on the rock wall in front of him. Then I saw Chen Kai pinch the seal with both hands......

There is something strange about this rock wall. Because Chen Kai's spiritual sense had no way to penetrate this rock wall to investigate the situation inside. Just now, it was precisely because the spiritual sense swept this rock wall and discovered this that Chen Kai would come over and take a closer look.

Chen Kai completed the legal decision in the blink of an eye. A 'Starlight Spell' struck directly at the rock wall.

Rumble!

The Starlight Spell smashed on the rock wall, causing the mountain to seem to shake slightly, but the moment the rock wall was hit by the Starlight Spell, Chen Kai's spiritual sense clearly found that a defensive shield-like power was stimulated from the rock wall, resisting the power of the Starlight Spell, so that the rock wall was not damaged in the slightest.

Chen Kai's eyes froze, staring at the rock wall in front of him with a satisfied smile. Now he was completely sure that this rock face was truly unusual.

Luo Shuang on the side also saw the situation just now, and saw that Chen Kai's starlight spell had not even damaged half of the rock wall, so he was taken aback, looked at Chen Kai and asked, "Chen Kai." What's going on? ”

Chen Kai glanced at Luo Shuang and said, "It's okay, it should be the power of the defensive formation just now." I'll use the magic weapon to keep bombarding later, and just blast that formation directly. ”

Chen Kai didn't know what kind of defensive formation was hidden in the rock wall, so he could only use brute force to crack it by the most stupid method. Thinking about it, if this is really left by Qin Shi Huang, this formation has been more than 2,000 years old, and the remaining power will not be so strong.

"Oh, then I'll wait for you right here." Luo Shuang responded. She knew that she basically couldn't help at this time, so she simply watched from the side.

"Hmm." Chen Kai nodded to Luo Shuang. Immediately, the bronze bell was directly sacrificed. Then he activated his true qi and cast a spell to activate the power of the bronze bell to bombard the rock wall......

While! Dangdang!

The loud and majestic sound of the bell resounded between the mountains in an instant, and the bell body that had risen to a diameter of a few feet slammed into the rock wall, knocking the whole mountain to tremble.

However. However, the defensive shield in that rock wall kept activating to resist the impact of the bronze bell, and it was impossible to destroy the rock wall itself.

Time passed imperceptibly, and most of the true qi in Chen Kai's body had been consumed. However, at this moment, the defensive formation in the rock wall still showed no signs of being breached.

It seems that the defensive formation inside the rock wall is indeed not simple. It was much more difficult to break through this formation than Chen Kai had imagined just now.

Because the rock wall could shield the spiritual sense, Chen Kai's spiritual sense could not penetrate into it to investigate the situation of the defensive formation. Naturally, there is no way to break the formation directly. The only way he could do it now was to rely on brute force to break the formation.

It's just that when Chen Kai turned around and began to use the True Yuan to urge the bronze bell, the defensive formation was still unbreakable. Until Chen Kai's True Yuan was consumed, the formation was still not broken!

This made Chen Kai frown.

And because there is not much true yuan and true qi left in the body. He could only stop for a while, put away the bronze bell, and stepped aside to prepare to meditate to restore the true yuan.

Seeing this, Luo Shuang couldn't help asking, "Chen Kai, can't that formation be broken?" ”

"Well, that formation is much stronger than I thought. It's not so simple to break through from the outside by brute force. Chen Kai responded.

"So what to do?" Luo Shuang asked.

Chen Kai said: "I'll restore the true yuan first, and then think about it later, if I can find another way." Otherwise, you can only continue to try to see if you can break the formation. ”

"Well, then you quickly recover the true yuan, and I will help you protect the Fa."

"Good!"

At that moment, Chen Kai sat down cross-legged on a stone beside him and began to urge the mental method to restore his strength......

Half an hour later, Chen Kai's strength was completely restored. He walked over to the rock wall again and looked at it carefully for a while, then his heart suddenly moved, and he directly took out the golden puppet from the mustard seed space of Tianxingyan.

Originally, Chen Kai was going to try to see if he could break the defensive formation by controlling the golden puppet, but when he took out the golden puppet, an unexpected change occurred.

I saw a white light suddenly lit up at the center of the golden puppet's eyebrows, and then, the Taiji Yin Yang Fish Jade Pendant that was originally sunk in the depths of the golden puppet's eyebrows actually emerged on its own, and also shot out a light intertwined with yin and yang and hit the rock wall......

Chen Kai was completely stunned when he saw this scene. Especially when there was a sudden tremor on that rock wall, and then a large piece of the rock wall disappeared directly, revealing a large hole, I was even more surprised.

"Could it be that jade pendant is still the key to unlock the defensive formation here?" Chen Kai thought in surprise in his heart, and at the same time, his eyes involuntarily looked at the Taiji Yin Yang Fish Jade Pendant at the center of the golden puppet's eyebrows.

At this time, the jade pendant had gradually disappeared into the depths of the golden puppet's eyebrows with a halo of light, and disappeared.

Luo Shuang was also startled when she saw a big hole suddenly appear in the rock wall in front of her, and she didn't know what was going on at all. I just saw that Chen Kai had just taken out the golden puppet, and then I saw that a light suddenly shot out from the forehead of the golden puppet and hit the rock wall, and then the rock wall underwent such a change.

"Chen Kai, this is ......" Luo Shuang couldn't help but speak.

Chen Kai shook his head at her and said, "I'm also surprised. Just now, I was just going to use the golden puppet to try to see if I could break the formation, but I didn't expect such an unexpected change to occur. ”

"But if nothing else, that Taiji Yin Yang Fish Jade Pendant should be the 'key' to open here."

As he spoke, Chen Kai had directly swept his spiritual sense into the cave. This time, Chen Kai's spiritual sense was not blocked out again, but went into the cave smoothly.

Chen Kai's spiritual sense could only extend a distance of about thirty meters, and within the extension of his spiritual sense, the cave was completely a deep tunnel, and there was nothing else.

As for the rock wall of the cave, it is still blocked by a layer of power. It seems that the formation itself should be arranged inside the rock wall of the cave tunnel.

"Keys?" Luo Shuang was stunned, obviously she didn't expect that the ancestral half of the jade pendant in her family would actually be the key to open here!

"So, let's go in now?" Luo Shuang asked.

Chen Kai shook his head and said, "Wait a while, I'll control the golden puppet to go inside first to see the situation, so as not to have any organs or killing arrays, talismans and the like." ”

After all, he didn't know anything about the situation inside, and his spiritual sense couldn't investigate the situation inside the stone wall of the cave, and he didn't know if there was any hidden mechanism or anything like that, could Chen Kai not be cautious?

"Well, good!" Luo Shuang nodded in response.

Chen Kai sat down directly on the ground next to him at the moment, and then invaded a spiritual sense into the golden puppet and entered the jade pendant in the control hub.

Then Chen Kai took the golden puppet and stepped into the cave......

The inside of the cave was dark, but the vision of the Jin puppet was not affected in the slightest, and the situation inside the cave that Chen Kai saw was almost no different from the outside, and all of them could be seen clearly.

Walking in all the way, although he was controlling the puppet of the Jin people, Chen Kai still maintained enough vigilance and was very cautious. At the same time, from time to time, he stomped the ground with his feet, or scratched the rock walls on both sides with the palms of his hands.

The purpose of this is naturally to test whether there is a mechanism.

Chen Kai himself may not be afraid of ordinary organs, but Luo Shuang can't compare with him. For the sake of Luo Shuang's safety, Chen Kai naturally had to be cautious.

Unconsciously, Chen Kai had already taken the Jin puppet into the cave for about 100 meters, but he never found anything.

The tunnel was confirmed to have been excavated by hand, but nothing else has been found.

There are no mechanisms, no murals or writing on the rock wall, and there is nothing else in the tunnel, so it is just a smooth tunnel to enter...... (To be continued......)
