After about ten moves like this, Gu Dan's face suddenly changed, and he looked at Zhang Dachuan in shock.

Because he suddenly found that Zhang Dachuan's speed was getting faster and faster.

Before, he was still barely following his own style of defense and counterattacking, blocking an average of five punches to return a punch, but now he has completely achieved one punch for one punch with himself.

What's even more terrifying is that his punch strength is also stronger than one punch, as if there is no limit.

Gu Dan thought of a possibility, so he became more and more frightened:

He's improving, he's improving in battle!

How is this possible?

He has only entered the Bone Refining Realm for two days, and the realm may not be stable, and now he is still making progress in battle, which is simply unreasonable!

How can there be such a person in the world?

Weakness, you must find his weakness, otherwise if you continue like this, you will definitely lose!

Collecting his mind, Gu Dan took advantage of the gap between the attacks and began to look for Zhang Dachuan's weaknesses.

Martial artists in the Bone Refining Realm, because of the different positions of bone refining, will cause a situation similar to "unbalanced development" in the body: for example, people who focus on refining leg bones will have weak upper limb strength; People who focus on refining their left arm will obviously lose a lot of weight on their right arm, and so on.

In normal combat situations, this kind of weakness will not affect the overall situation, but in the confrontation of the same realm with equal strength, it is very important to find the weak point of the opponent.

Because two martial artists of equal strength, if they really don't die, they will fall into a very long tug-of-war situation...... There were once two martial artists in the middle stage of the Bone Refining Realm, and when they were each other, they fought for a day and a night before they were exhausted.

So if you want to solve it quickly, Gu Dan must find Zhang Dachuan's weakness.

Taking a deep breath, Gu Dan cheered for himself in his heart while fighting Zhang Dachuan:

"He's just started refining his bones, and his weaknesses should be obvious, just feel the strength of his left and right hands and feet."

"Calm down, be calm, there must be flaws."

However, after more than a dozen moves in this way, Gu Dan found in despair that he couldn't tell whether Zhang Dachuan was refining the hand bone or the leg bone, whether it was the left or the right.

Zhang Dachuan's limbs are completely identical, and they all have extremely strong destructive power.

He has no shortcomings!

After realizing this, Gu Dan's heart fell to the bottom.

Is it really going to lose today?

Thinking that he would lose to a junior who had just entered the Bone Refining Realm for less than two days, Gu Dan was angry and even a little frightened.

If it weren't for Ning Hao's order, he wouldn't want to be an enemy of Zhang Dachuan even if he was killed.

With such a distraction, Gu Dan's hand moved half a beat slower, and Zhang Dachuan, who had just withdrawn his fist, instantly lit up and seized this once-in-a-lifetime opportunity.

With a shout, Yunbu moved instantly, with his toes as the axis, his waist and hips exerted force, and he turned around with his body, and he actually came behind Gu Dan.

Then, Zhang Dachuan rounded his fist and smashed it into his cheek.

Gu Dan reacted quickly, and Xiao Xiaobu forced his body half to the right, and at the same time crossed his hands on his chest to make a blocking posture.

It was the first time since he started fighting that he had given up attacking and switched to defense.

Rumble!

A huge force struck, Gu Dan felt like he was hit by a speeding truck, and the whole person was blown out by Zhang Dachuan's punch, and his back was slammed against the cement pillar, and his eyes were full of pain.

didn't have time to catch his breath, the figure in front of him flashed, and Zhang Dachuan had already caught up with him, hitting Gu Dan's door with a heavy fist.

Gu Dan subconsciously raised his right arm to block, but the next moment, Zhang Dachuan turned his fist into a claw and grabbed Gu Dan's right wrist fiercely.

With a "hey", Zhang Dachuan showed Gu Dan a creepy smile:

"Finally caught."

"What?"

Gu Dan was shocked and desperately wanted to withdraw his right hand, but Zhang Dachuan's palm grabbed Gu Dan's right wrist like an iron tong, no matter how hard he tried, he couldn't shake Zhang Dachuan away.

Finished.

Gu Dan thought desperately.

The next moment, Zhang Dachuan's thunderous fist smashed towards Gu Dan's left shoulder.

Because his right arm was restrained, Gu Dan could only meet it with his left fist.

But his left fist has not been tempered, compared to the powerful right arm, how can he block Zhang Dachuan, who is full of fire and has a steady stream of power?

After blocking the three punches, Gu Dan was shocked to find that in his left arm, there was a strange internal strength that was crispy and numb at some point.

Whenever this numbness appeared, his accumulation would be interrupted, and he would have to rebuild his strength.

This is exactly the thunderous internal strength of Zhang Dachuan's thunder fist.

Different from the basic martial arts of the Ning family mastered by Gu Dan, the Thunder Fist is an extremely clever boxing technique, in addition to punching like a thunderbolt, it will imperceptibly turn the cultivator's internal strength into a thunderous internal strength containing the power of thunder in a long period of time.

This internal strength is magnificent, extremely fierce and domineering, can drive away all evil and filthy things, can suppress all yin and evil spirits, and punch out, the demon will retreat.

Of course, Zhang Dachuan, who has only practiced thunder boxing for a few days, can't exert one-tenth of the power of thunder boxing now, but he does already have a weak thunder internal strength in his body.

And when the two of them bombarded with their fists, these thunderous internal forces collided with Gu Dan's internal strength, and then dissipated into the air.

The spilling out thunder internal energy had silently invaded Gu Dan's arm at this time, stimulating the muscles and nerves in his arm like an electric current, interfering with his movements.

Although this kind of interference is only about a thousandth of a second, in the life-and-death struggle, this time is enough to make and break the tide of the battle.

Finally, when Gu Dan raised his left fist again to block Zhang Dachuan's attack, the numb thunderous internal strength shattered Gu Dan's fist that had gathered strength.

Zhang Dachuan shouted, and the thunder fist slammed into Gu Dan's chest without hesitation, blasting him out like a cannonball.

Gu Dan screamed and slammed into the wall of the factory, smashing the cement wall skin on the wall into dense cracks, like spider webs.

"Poof!"

Gu Dan spat out a mouthful of blood, and the world was spinning in front of him.

He was in pain everywhere in his body, but his chest was jammed, he only felt that his breathing had to use the strength of feeding, his heart was pounding and beating wildly, and the rushing blood was about to squeeze his brain.

Before he could adjust his breathing, he felt his body light, but it was Zhang Dachuan who came to him in an instant, and then kicked him high and flew away.

Gu Dan was like a sack, thrown up three meters high, and then fell heavily on the hard ground, making a "pop" sound.

Gu Dan struggled and wanted to get up from the ground, but as soon as his arms supported his upper body, a huge force came from his back, and he was trampled under his feet.

Zhang Dachuan looked at Gu Dan condescendingly, the corners of his mouth hooked slightly, and let out a contemptuous mockery:

"Now, do you still think you can kill me?"
