The sudden roar did not make Lu Chen fall into panic and uneasiness anymore, on the contrary, when this roar sounded, he found that his senses suddenly increased several times at this moment. That wasn't what it looked like when you were practicing Qi from the fifth to the sixth layer, this was clearly an extremely obvious leap.

The true element of the mana of a monk in the Qi training period exists in the form of a gaseous state, and from the stage of Qi training to foundation building, it is necessary to continuously condense the mana and slowly transform the gas state until it becomes a liquid state, which is the master of the foundation building period. And the process from gaseous state to liquid state, only the seventh layer of qi can feel a little bit. This is a change in the fundamental quality of the true element of mana, and it is precisely this realm that can control the flying sword......

"Seven layers of Qi training?" Lu Chen looked at his hands in disbelief, the pain just now had long since disappeared, but what he had gained was infinite strength and incomparably majestic mana.

"This is less than the time for tea, and you will reach the seventh layer of qi training? Damn, even if you can't eat Blue Leaf Xinzhi in the future, it's worth it, now is the right time to reach the seventh layer, this time Li Yangchao is here, I, Lu Chen, am not afraid of ......"

In the excitement, Lu Chen's eyes faintly flashed with bright light, like two strong lights in this dark cave......

"Huh?"

Lu Chen, who was excited, didn't know how to be good, glanced at it lightly, and suddenly in the deepest corner of the cave, there was a little blue and white color beating, as if it was a blue fire in the middle of the night, extremely mysterious.

Lu Chen was bold, moved over step by step, and first tapped a little with the tip of the long sword, and the hard touch immediately spread from his fingers to his wrist and extended to his whole body.

"Is it a stone?" Lu Chen thought for sure.

Since there was no danger, Lu Chen's courage gradually grew, and he slowly walked to the shimmering blue and white stone and squatted down to take a look.

The stone was very strange, the blue and white color was not very obvious, and it was embedded in the cracks on the surface of the cave, only the pointed end was exposed, obviously only the head was exposed, but Lu Chen could still feel an extremely strange and pure aura coming from the stone.

"Huh?" Lu Chen looked at the place where he had just picked the Blue Leaf Mushroom, and then looked at the four walls of the cave, and suddenly found that there were three slender traces starting from the tip of this stone and spreading to the place where the Blue Leaf Leaf Mushroom had just grown.

After pondering for a while, Lu Chen suddenly understood: "No wonder there will be blue leaf heart mushrooms here, it seems that it must be the lingzhi here that absorbed the essence of this stone and transformed into blue leaf heart mushrooms for many years." Isn't this stone already in existence for a hundred years?"

Thinking of this, Lu Chen's eyes began to glow.

It is not difficult to guess that if the essence of this mysterious stone can be formed, and the breath on this stone is still so pure after at least a hundred years, the value of this stone should be far greater than that of Blue Leaf Ash.

"The value of Blue Leaf Xinzhi is 100,000 spirit stones, and this stone ......" Lu Chen almost didn't dare to think about it.

"No matter...... This thing must be a treasure, take it first and then talk about ......"

Thinking of this, Lu Chen clenched the hilt of his sword and gently slashed a few times in the cracks in the ground, the surface of the cave was not too hard, so as not to be afraid of the stone being damaged, Lu Chen deliberately dug a small pit near the surface and dug the stone out of the ground.

The blue and white stone has a cold feeling, as if it is a cold and piercing ice breath. Lu Chen took it in his hand and dragged it, and looked at it steadily......

"Well, it's about the size of a palm, with a round tip at the top...... If the underside is also pointed, it is a prism. ”

I checked it in my hand, it was very heavy, and it was estimated that there was at least two or three catties of weight, obviously the density of this blue and white stone was extremely high, and the texture was also very good.

After looking at it for a while, Lu Chen was about to put it away, but when he took the stone to his chest and was about to take out the Qiankun bag, suddenly a black light flashed out from his chest. This black light was obviously emitted by the jade pendant on his chest, and Lu Chen was slightly stunned. At this moment, the blue and white stone that he had just gotten in his hand suddenly stuck tightly to the jade pendant......

Follow......

The blue-and-white color begins to fade...... Lu Chen clearly felt that the pure aura in the blue and white stone was passing wildly, and it did not cause too much turmoil in the cave, obviously, his jade pendant was absorbing the energy of this stone......

"I ...... I...... Damn, don't ......"

It was something more valuable than Blue Leaf Xinzhi, and his jade pendant was obviously like a bottomless pit, and the blue and white color on the stone that was tightly attached to it was fading very quickly. If the jade pendant is allowed to absorb it like this, it will not take long at all, and this stone is estimated to be wasted......

Lu Chen shouted anxiously, desperately grasping the blue and white stone and the jade pendant with both hands, trying his best to separate the two stones. It's just that no matter how hard Lu Chen tried, in the end, he even used his strength to eat, and he still couldn't separate the two.

As a result, Lu Chen could only scold but impatiently watched the color of the stone getting darker and darker...... Eventually, it turned into a gray, ordinary rock.

"Pop ......"

The blue and white stone lost its color, and naturally lost its previous pure aura, as if an ordinary stone automatically detached from the jade pendant and fell to the ground.

Lu Chen's eyes widened, and bloodshot began to spread under his white eyes: "My baby, ......"

After a few breaths of silence, Lu Chen finally crawled on the ground with a sad face, watching the stone that should have been priceless become an ordinary stone, Lu Chen's hatred: "The good baby is gone." ”

"Damn Jade Pei, what the hell are you? Lu Chen stood up angrily, ripped off the jade pendant, and clenched it in his hand hard, angrily wanting to crush it.

Of course, Lu Chen has already seen the sturdiness of this jade pendant, not to mention that he, a monk in the Qi cultivation period, is helpless with the jade pendant even if he used to be Chen.

What is this jade pendant that can make him murderous and implies that he doesn't know what secrets? What is it hidden? Lu Chen has no way of knowing, except that he is a relic left by his mother, in Lu Chen's eyes, it is simply an ordinary jade pendant. But it was this jade pendant that made him lose a treasure that should have been priceless today......

"Boss, are you a human or a ghost?" Lu Chen took the jade pendant and put it in front of him, and roared at a loss.

Obviously, no matter how annoyed, angry, or even insulting Lu Chen was, Yu Pei would not give him any response at all.

Turning it over and over again, Lu Chen almost threw the jade pendant to the ground and stepped on two feet. And at this time, when Lu Chen's resentful eyes suddenly swept to the jade pendant, he was suddenly stunned, he found that the three cracks that originally existed on the jade pendant suddenly disappeared, and the place where there should have been a crack became extremely smooth at some point......

"Hmm? What's going on? Could it be that it absorbed the energy of the stone, and the jade pendant repaired itself?"

Lu Chen noticed something strange and thought about it carefully, but in the end it was still in vain. But this discovery made him no longer have the frustration he had just had......

The jade pendant is a relic of the mother, and you must keep it well, and this jade pendant is not useless. At the beginning, if it weren't for his help in the Great Zhou Dynasty, it would have been impossible for him to kill the seriously injured Li Silkworm, and the amazing murderous aura originated from the jade pendant.

"The jade pendant is weird, since the blue and white stone can be repaired by the jade pendant itself, it is better to go back to Lin Hongjin and ask, if you get two more blue and white stones, you will definitely be able to repair the jade pendant back. Well, that's it......"

With a plan in mind, Lu Chen looked around, and when he saw that there was nothing else around, he got up and left the cave.
