"You have a sharp tongue, I hope your strength can be as sharp as your words!"

Mu Tianxing gritted his teeth, his face full of disdain. What qualifications did this guy have to be so calm in front of him?

"Let's end this battle!"

Gu Yuan muttered, and then his feet shot out.

He took the initiative.

Gu Ting in the room was still tied up tightly in place, unable to move.

But she could see the scene outside through the door.

"Is this guy crazy? How dare he take the initiative to attack?"

Gu Ting found it unbelievable. This guy really surprised her.

"If I'm not mistaken, the blood-red flame on his body should be a demonic fire, right? But demonic fire should only be produced by level five demonic beasts. Without three Spirit Kings, it is impossible to take down the demonic fire of a level five demonic beast. Who is this guy?"

Gu Ting has now begun to doubt Gu Yuan's identity, thinking that he might not be as simple as he seems. However, Gu Ting really doesn't know if there is any big family with the surname Gu nearby. Even if there is, they are just some very small families, which should not be possible.

"It seems that we need to send someone to conduct a thorough investigation after we return. I'm curious about this guy's true identity."

Gu Ting murmured, then frowned, looking at the two people fighting in the yard with some worry.

As for Gu Yuan, Gu Ting didn't feel that she had any friendship with him after only knowing him for two or three days. It was just that Gu Ting didn't like to owe others anything, and she still owed Gu Yuan a favor.

Gu Yuan saved her. If it weren't for Gu Yuan, she might have really died in the desert. This is something that cannot be forgotten.

Moreover, the cause of today's incident was Gu Ting herself. If Yuwen Feng had not exaggerated the matter and told Mu Tianxing about it, they would not be fighting together now.

"I hope nothing happens to you, otherwise I will be the one feeling guilty!"

Gu Ting was speechless and just watched the two people in the yard playing games.

boom--

A loud roar was heard, and the two figures quickly separated and retreated in opposite directions.

The stone slabs under his feet burst, and Gu Yuan steadied himself. Looking at the completely deformed Lingyuan heavy sword in his hand, he felt heartbroken and secretly horrified at the same time.

The Lingyuan heavy sword was severely deformed and many cracks appeared on it. It looked like it was completely useless.

However, the Lingyuan Heavy Sword is a fourth-grade spiritual weapon, and it was produced by the system. However, in this moment of confrontation, it was deeply deformed by Mu Tianxing's physical strength. It can be imagined how abnormal the physical strength of this guy Mu Tianxing is.

"Hehehe, your weapon is broken, so feel free to use whatever tricks you have."

Mu Tianxing looked at his hands. Although he had destroyed Gu Yuan's heavy sword, he also paid an unknown price.

The red flames on the heavy sword were actually not that easy to deal with. Mu Tianxing's hands were charred black, and even had a fragrance coming from them. There were several places where the wounds were so deep that the bones were visible, and the injuries were not light.

But relatively speaking, it was Gu Yuan who suffered the loss.

Although Gu Yuan felt sad, there was nothing he could do. After all, this fourth-grade spiritual weapon was just a fourth-grade spiritual weapon, and it was not something that would last forever. Since it was destroyed, he would have to find a better one in the future!

Thinking of this, Gu Yuan felt a little better.

Gu Yuan raised his head and looked at Mu Tianxing, a dangerous look flashed in his eyes, and said: "It seems that your physical strength is very strong. It just so happens that I have trained my own body, so I want to try a physical contest to see how strong you are!"

"Huh? Comparing physical strength with me? Hahahaha, are you dreaming?"

Mu Tianxing laughed out loud. What a joke! He, Mu Tianxing, was of stone attribute and had never stopped practicing his physical defense since he was a child. Apart from this, his attack was equally terrifying. It could be said that he was truly capable of both offense and defense. So how could this Gu Yuan compare with him?

"Can you give it a try?"

Gu Yuan put away the scrapped Lingyuan heavy sword in his hand. After all, it had been with him for many years and needed to be treated well.

Then Gu Yuan looked at Mu Tianxing, turned his head, and said to Mu Tianxing: "I have never believed in evil. The more impossible something is, the more I firmly believe that it will happen!"

"Oh? You mean you can defeat me?" Mu Tianxing asked with a sneer.

"Haha, let's wait and see!"

Gu Yuan twisted his feet and his body shot out. The spiritual energy in his body seemed to have exploded, instantly increasing its output by several levels and gathering madly towards Gu Yuan's entire body.

“Ahh!”

Looking at the attacking Gu Yuan, Mu Tianxing clenched his fists again, and then rushed forward at night.

boom--

boom--

The sound of fists colliding continued to ring out. Gu Yuan's fists, arms, elbows, and even legs turned into his own weapons, beating Mu Tianxing fiercely.

Mu Tianxing was calm and fearless. He confidently defended himself and let Gu Yuan bombard him.

"snort--"

Mu Tianxing punched Gu Yuan's crossed arms, and Gu Yuan felt a burning pain in his arms.

Shaking his hands, Gu Yuan grinned. He had to admit that Mu Tianxing's physical strength was truly terrifying.

The fate of the Lingyuan heavy sword also proves this point.

Gu Yuan slowly spread out his hands, and then a blood-red flame ignited on his body.

"Next, let me see which one is stronger, your defense or my Red Flame!"

The red flame seemed very spiritual in Gu Yuan's hand, sometimes turning into a small snake, sometimes into a small bird, coiling or standing in Gu Yuan's palm, which was quite pleasing.

But Mu Tianxing didn't think so. When the red flame appeared on Gu Yuan's body, he had been on guard against this thing. Although he knew that Gu Yuan's strength was lower than his, Mu Tianxing still didn't dare to be careless.

Because he knew that whoever underestimated the demon fire would suffer.

Of course he understood the power of the demon fire. Being able to refine a demon fire would bring absolutely terrifying improvement to his own strength.

Apart from anything else, Mu Tianxing's father had refined a demonic fire by chance, and with this, he successfully became the great elder of the Mu family, and he was the only one who could rival the clan leader in strength.

This is the charm of the demon fire.

So when Mu Tianxing saw the demon fire in Gu Yuan's hand, his first reaction was actually jealousy.

Why can he possess this magical thing while I can't?
