When he saw that square seal, Gu Yuan immediately remembered that this was the "gift" that Wei Xuanyi had received from the Holy Monument when he graduated from the Martial Arts Academy before.

However, before, Wei Xuanyi didn't know the use of this square seal, but now, she was able to control it flexibly, it seems that during the time she was not in Star City, Wei Xuanyi had studied this square seal carefully.

After all, it is a gift from the Holy Monument, how can it be bad? Look at Ge Fei, who was invincible with the bow given by the Holy Monument, and the children next door were crying.

At this moment, from the square seal that emitted a streamer, Gu Yuan felt a surging energy surging in crimson, like a giant beast from the desolate wilderness, bringing an endless sense of oppression.

With a "boom", the phantom fell, completely suppressing the black shadow, and in a trance, Gu Yuan and the others seemed to hear the screams of the black shadow.

However, observing Wei Xuanyi's expression at the moment, it can also be seen that maintaining Fang Yin's form at the moment is still quite a big drain on her.

In an instant, the brilliance dimmed, the phantom disappeared, and only the corpse of the crystal square seal was pressed to the ground, and as for the black shadow, it had turned into a pool of black viscous liquid at this moment, completely losing its vitality.

Gu Yuan swept away the strong light, a sense of weakness swept over, and he stumbled under his feet, almost falling.

Kong Baihe walked a few steps quickly, and wanted to take a closer look at the square seal, but Wei Xuanyi stretched out his hand, and the square seal returned to his hand.

"What kind of magic weapon is this? It's amazing! Let me see. Kong Baihe approached.

"Look at what, look!" Wei Xuanyi glanced at him, put away Fang Yin, and hurriedly walked to Gu Yuan's side, holding his arm, "How is it, are you okay?" ”

Gu Yuan shook his head, looked at Wei Xuanyi, and said with a smile, "Have you found a way to control that seal?" ”

"Well, do you like it? I'm sending you! Wei Xuanyi took out the square seal again.

Kong Baihe was almost not.

Okay! I can't even look at it, Gu Yuan just asked, are you going to give it to him?

It's okay to be different, but it can't be so outrageous, right?

"Actually, I didn't know what this thing was for at first, but then my grandfather told me that I could try it by infusing it with true yuan and then dripping it with blood.

I tried it, and this thing was recognized, and a lot of things appeared in my head, such as control essentials and formulas. Wei Xuanyi explained with a smile, "This is called the Demon Seal, right?" ”

"Awesome!" Gu Yuan gave a thumbs up.

Wei Xuanyi's Demon Suppression Seal was indeed extraordinary, and thinking back to the sense of oppression he felt just now, Gu Yuan could only exclaim twice.

"Do you want it or not?" Wei Xuanyi urged.

"No...... Keep it for yourself. Gu Yuan couldn't cry or laugh, "This is a baby, you put it away, don't be accidentally robbed by others." ”

"Got it!" Wei Xuanyi pursed his lips and put away the Demon Suppression Seal again.

Bao Mingchuan and others slowly recovered.

They walked up to them and looked at the black, viscous liquid on the ground, their faces horrified.

"That's what it is...... The monster? ”

Kong Baihe looked at Gu Yuan's somewhat pale face at this time and said, "How is it?" Do you want to take a break first? ”

"No, you don't." Gu Yuan waved his hand, took two quick steps, summoned the door of sacrifice, and sacrificed the demon soul of the shadow demon.

Kong Baihe was quite emotional.

"Gu Yuan is really a good and conscientious person, obviously so weak, and he is still in a hurry to get on the clock......"

Wei Xuanyi glared at him fiercely.

And Bao Mingchuan on the side, when they saw the door of sacrifice, they once again showed a look of surprise.

"This ...... What kind of immortal means is this! ”

Hearing such a discussion, Gu Yuan's heart was quite strong.

It wasn't until the golden sacrificial gate turned into brilliance and returned to Gu Yuan's body that he found a place to sit down and gasped for breath.

After that, the demon soul was sacrificed, and the dust was settled.

Fortunately, this shadow demon is just like Luo Yin said before, good at concealment, and his strength is average, if his combat power is also off the charts, I am afraid he will have to become one of the most difficult monsters Gu Yuan has encountered so far.

Gu Yuan looked around and suddenly became puzzled.

"Where's Bai Ming?"

"Here's it." Bai Ming suddenly appeared at the door of the art museum, looked at it for a while, and then walked in.

This one walked and muttered.

"It's scary...... This battle of yours is too scary......"

Gu Yuan saw that he was coming in from outside, and said in surprise, "When did you go out?" ”

"When that seal comes out." Bai Ming shook the windbreaker on his body, "I'm afraid that I will be accidentally suppressed." ”

Speaking of this, Bai Ming snorted, looking a little apprehensive.

Gu Yuan looked at Bai Ming's cautious appearance at the moment and laughed.

"Everyone is their own person, what are you afraid of......"

"That's what I said, but the two of you, one can kill me, and the other can sacrifice me by the way, who is not afraid." Bai Ming didn't have a good airway.

This is really sending the Buddha to the West.

Immediately, Bai Ming said again: "This shadow demon, the strength is average, it is also a C-level monster, it is this concealment and speed, it is too scary, if I have this means, my strength can be improved a lot." ”

Gu Yuan was also pondering at the moment.

The demon soul of the shadow demon has been sacrificed by himself, but he doesn't know what spiritual energy he can get from it.

Both the speed and the wonderful stealth ability seem to be good......

After resting for a while, Gu Yuan got up and left the art museum with Bai Ming.

As for the rest of the things, it was Bao Mingchuan and they solved it.

Back in the café, Gu Yuan sat on a chair and talked to Zhou Zhen about the situation of the shadow demon.

Zhou Zhen was amazed.

"Shadow Demon ...... This kind of monster is rare. ”

Anyway, he was unheard of and unseen.

When Gu Yuan elaborated, Zhou Zhen was also recording and preparing to archive.

After Gu Yuan finished speaking, Zhou Zhen also nodded.

"Okay, it's not too early, you should go back and rest early, and we'll talk about it tomorrow."

Whether it was Gu Yuan's "strong light" or Wei Xuanyi's "square seal", the consumption of the true yuan in their bodies was very large, and Zhou Zhen could see it at a glance.

In comparison, Kong Baihe's condition seemed to be very good, so Zhou Zhen arranged for him to drive Gu Yuan and Wei Xuanyi back together.

Driving the car, Kong Baihe sighed a little.

"It's obviously a case that we solved together, how do you feel that I'm paddling?"

"There will be a time for you to perform in the future." Gu Yuan, who was sitting in the co-pilot, smiled.

Kong Baihe's fingers tapped lightly on the steering wheel, turned his face to look at Gu Yuan, and quickly turned his head to look ahead.

"Gu Yuan, we are also our own people now, the strong light in the art museum before...... Don't you tell me about it? ”

Gu Yuan closed his eyes and was silent for a long time, and suddenly launched a soul torture on Kong Baihe.

"Do you believe in light?"

"......" the corners of Kong Baihe's mouth twitched, "I don't believe it." ”

"He who does not believe in the light is not worthy to know."

"Then I believe it."

"He who believes in the light...... You have the answer in your heart. ”

Looking at Gu Yuan's tired appearance of being too lazy to speak at this time, Kong Baihe only had five words in his heart.

You can't die!
