"Is this the Demon Source Crystal?" Shen Lang was shocked.

He read the statement about the Demon Source Crystal in the Qianyuan Record of Emperor Xuan. This thing is the supreme treasure that demon cultivators dream of, and is even more valuable than the Yuyang Thunder Crystal.

The Demon Source Crystal contains extremely amazing pure demonic energy. The magic cultivator absorbs the demonic energy in the Demon Source Crystal to practice, which will greatly increase the power of his own martial arts.

Moreover, the Magic Source Crystal is also the top-level material for refining magic weapons. After ordinary magic weapons are mixed with the Magic Source Crystal, their power can be increased by at least twice!

Due to the various characteristics of the Magic Source Crystal, this kind of thing has no market value and is one of the extremely precious materials in the cultivation world.

The Demon Source Crystal has not appeared on Yunjian Continent for thousands of years, and Shen Lang has taken a big advantage. He really didn't expect that there was such a thing in this ancient beast.

Obtaining a magic source crystal is a good omen for Shen Lang and Su Ruoxue.

After the big octopus died, a large amount of black ink poured out of the body, and a large area of ​​lake water was dyed black and the surroundings became pitch black.

The black ink is highly poisonous, and Shen Lang immediately removed the transformation and pulled Su Ruoxue's arm. He pinched his single finger and condensed the sword and shield to cover the two of them, and inspired the Holy Yang War Qi to defend against the erosion of the ink.

The two of them did not stay and quickly passed through the broken space in the air from the bottom of the lake. When they reached a safe distance, Shen Lang accidentally discovered something was emitting light in the dark lake water.

"Hey, what is that?" Shen Lang's face changed, and he was about to dive into the water to see what was going on.

"Be careful!" Su Ruoxue showed a hint of worry on her pretty face.

There can be terrifying ancient beasts like big octopus at the bottom of this lake, and maybe there are any other dangers.

"Don't be afraid if I'm here." Shen Lang patted the woman's shoulders and said, "Xue'er, why don't you leave the bottom of the lake first and I'll go down alone to take a look."

"I am not that timid yet, I'll be with you." Su Ruoxue held Shen Lang's hand tightly and curled his lips, as if he was a little complaining that Shen Lang always liked to act alone.

"Okay." Shen Lang scratched his head, then pulled Su Ruoxue, and the two of them dived to the bottom of the lake.

The ink overflowing from the octopus's corpse had spread under the lake, and the shield formed by the sword shield and the Holy Yang war energy protected the two.

Shen Lang flew towards the place where the light shone at the bottom of the lake. The more he dived, the more the Yin and Demonic energy spreading in the bottom of the lake became heavier, and I don’t know how it was produced.

Soon, the two finally dived to the bottom of the lake.

"Is this?" Shen Lang showed curiosity.

There are traces of formations under the lake!

It is a star-shaped formation, about a range of about a hundred square meters, made of a large number of black stones, carved with a large number of golden runes, which are complex and mysterious.

In the center of the formation, there is a small stone pillar. There is a bowl-shaped groove on the top of the stone pillar. A milky white round bead is placed in the groove, roughly the size of a ping-pong ball.

It was this milky white bead just now, emitting a gorgeous white light, giving people an extremely magical feeling.

Originally, this white bead would not shine easily, but it might be that the ink spreading at the bottom of the lake stimulated the object, causing the object to react.

Shen Lang could clearly feel that there was no black gas within a hundred meters around the white bead, and the ink was isolated.

It has such amazing protection against the filthy aura, and this thing must be a treasure!

After looking around the star formation and not finding any danger, Shen Lang couldn't help but reach out and tried to get the white round bead.

"Young Master, don't take this thing easily!"

Xiaorou flew out from the spirit beast bag on Shen Lang's waist, turned into a stunning girl, and grabbed Shen Lang's arm with an anxious expression.

Shen Lang felt a stern, immediately withdrew his hand, and said in surprise: "Xiaorou, why are you coming out?"

Su Ruoxue glanced at Xiao Rou who suddenly appeared, frowned and said, "Shen Lang, who is she?"

"Xue'er, she is the spiritual beast I told you before. The six-tailed heavenly fox can transform into a human form." Shen Lang immediately explained.

"Sorry, I was anxious just now." Xiaorou's pretty face turned red, and she also felt that it was inappropriate to happen like this. She immediately bowed to Su Ruoxue and said, "Xiaorou, I have seen Sister Su."

Su Ruoxue felt relieved and nodded, "Xiao Rou, don't be polite. I heard Shen Lang talk about you, you have helped him many times."

While saying this, Su Ruoxue looked at Xiaorou a few times.

This girl, who is transformed into a six-tailed fox, is a bit beautiful and charming. Her skin is as white as snow, her facial features are delicate and graceful, and her white hair is long and drooping to her waist. Especially her beautiful legs, she looks particularly slender and attractive.

Unexpectedly, the spirit beast in Shen Lang's mouth could become such a stunning beauty, and after spending so many years with Shen Lang, Su Ruoxue suddenly felt a little uncomfortable.

Although Su Ruoxue has a strong desire to possess Shen Lang, she doesn't mind Xiaorou's existence. Even if Xiaorou is as beautiful as a fairy, she is just Shen Lang's spiritual beast, and there is no need to be jealous.

Shen Lang asked about the serious matter and frowned and said, "Xiao Rou, you are so nervous. Is there anything wrong with this formation?"

"Young Master, take a closer look at the bricks and stones at the bottom of this formation." Xiaorou reminded.

As soon as he finished speaking, Shen Lang and Su Ruoxue immediately looked underground.

Indeed, a trace of black air was slowly overflowing from the stones on the ground around the formation. Although the black air was dissipating very slowly, you could still feel the continuous flow.

The amount of black gas dissipated was very small, so Shen Lang did not notice it immediately before.

"Can the black gas at the bottom of the lake dissipate from the bottom of this formation?" Su Ruoxue raised her eyebrows.

Xiaorou nodded slightly and said, "Sister Su is right, it's true. This foul air will not easily dissipate after it overflows. Over time, a large amount of black air will spread to the bottom of the lake. It is not surprising that there are ancient beasts like big octopus. If Xiaorou guessed correctly, the formation at the bottom of the lake should be a reinforcement formation that seals the large array."

"Reinforcement formation?" Shen Lang was a little confused when he heard this. This was the first time he heard this statement.

Xiaorou explained: "Young Master can understand that after a seal formation is established, in order to prevent the formation from being unstable, a reinforcement formation is set up on its edge to increase the binding force of the overall seal formation. In ancient times, you human monks liked to use this method to suppress powerful demons!"

"It is very likely that there is a seal formation in this Holy Scar Canyon that suppresses the large demons! What the young master saw was the reinforcement formation attached to the seal formation. Moreover, under this reinforcement formation, the demonic energy was leaked, and it is believed that the seal formation had reached its limit." Xiaorou frowned slightly.

Shen Lang and Su Ruoxue looked at each other, and the Holy Scar Canyon was indeed extraordinary.

However, whether there is a demon sealing is not their business. Shen Lang pointed to the milky white beads on the groove of the stone pillar and asked curiously: "Xiao Rou, what is this white bead?"
