A huge muffled sound sounded from the place where their fists collided. A visible air vibration was emitted along with the sound, triggering a huge air wave. It blew up the dust in the martial arts arena and enveloped the two of them.

After the dust dissipated, the surrounding audience discovered that Brax was still standing in the center of the arena with a trace of caution. Chu Nan had retreated to a corner of the arena and was looking down at his right hand with a thoughtful expression.

The audience looked around, their faces revealing undisguised shock.

When Brax said that he had the strength of a fourth-stage Internal Breath expert, many people still did not believe it.

This was because although Brax looked much older than Chu Nan, he was only in his early twenties and was not much older.

Possessing the strength of a fourth-stage Internal Breath Realm at his age was extremely rare, and there were not many on the entire Purple Cloud Planet.

However, just from his punch just now, it had already sufficiently displayed that he already had the ability to completely release his Internal Breath. He had definitely reached the level of a high-level Internal Breath Martial Artist. It was really possible that he was already a fourth-stage Internal Breath Martial Artist, far surpassing most of the young martial artists present who had signed up to participate in the test.

However, this “vast majority” did not include Chu Nan.

Although Chu Nan had already proven his strength in the West Cloud Planet’s martial arts competition, no one had expected that he could actually face a punch from a fourth-stage Internal Breath Martial Artist like Brax. It looked like he was only at a slight disadvantage and was losing at all.

Did this Chu Nan’s strength really increase so ridiculously in such a short period of time? From being able to only take a full beating when facing a third-stage Internal Breath Martial Artist like Maruk, had he become strong enough to face a fourth-stage Internal Breath Martial Artist now?

If this was true, it was too unbelievable!

Chu Nan ignored the various thoughts of the surrounding people. He looked at his right hand and pondered silently.

He had indeed not put much effort in the first punch that he had launched just now. He had only casually thrown a punch. Apart from not wanting to listen to Brax’s nonsense and use this punch to trigger a battle, he had deliberately not used any martial technique to punch like this.

When this punch was thrown, he instantly felt that he had indeed changed very clearly from before.

Such a casual punch had nothing to do with the Hong Clan’s Long Fist, and its posture was far from perfect. However, he could easily mobilize his Internal Breath to attach to it, causing the force of this punch to be as high as 1277.716127 kilograms.

This had already greatly surpassed the special fist technique that he had used in the past. After complementing it with his powerful data ability, he could only use the most perfect posture to mobilize the strength he could unleash after his Internal Breath.

It was obvious that after opening all the meridians in his body, his Internal Breath could circulate throughout his body according to his will. The greatest effect on him was that he no longer needed to be fixed to a few moves and postures like before to unleash the greatest power.

The current him could easily mobilize his strongest Internal Breath with a raise of his hand. He was much stronger than before.

However, this also made Chu Nan discover his problem.

He had really grasped too few external martial techniques at the moment. Although the Hong Clan’s Long Fist was extremely special and could help him mobilize his Internal Breath to assist before he became an Internal Breath Martial Artist, this fist technique itself lacked variations and was completely not exquisite. It could be used to fight others head-on, but it was simply impossible to rely on his moves to obtain an advantage.

Before this, the reason why Chu Nan could gain the advantage in every enemy in the external martial arts competition was because he had an extremely powerful data ability that could instantly determine every detail of his opponent’s body and respond.

However, this response was undoubtedly too passive. When Chu Nan wanted to take the initiative to rely on his moves to obtain an advantage, the difficulty was extremely high.

Just like earlier, Chu Nan had deliberately not used the Hong Clan’s Long Fist because he wanted to test the experience he had learned from Xue Zhengming and see if he could obtain a major breakthrough in external martial techniques.

However, when he threw a punch, he immediately knew that there was a huge problem with this punch. It was completely disorderly, and then he was indeed struck by Brax’s powerful counterattack.

Fortunately, Chu Nan had comprehended the principle of “if the momentum is not halted, the strength can’t be exhausted” from Xue Zhengming. When he threw his punch, he had already held back a portion of his strength. When he saw that Brax’s fist was difficult to block, he instantly changed his move and used the Sitting Horse Stab Fist to block it.

If not for the fact that his Internal Breath had fused into his entire body and he could easily mobilize it with his mind, because he was caught off guard earlier, he would definitely not have had the time to mobilize his Internal Breath. Then, after being struck by Brax’s shocking two tons of punch, even if he did not vomit blood and die on the spot, he would have broken his arms and legs and directly lost his combat strength.

A fourth-stage Internal Breath Martial Artist was indeed different from a third-stage Internal Breath Martial Artist.

Although Chu Nan was completely passive when facing Maruk, he at least had the strength to resist.

However, if the Chu Nan at that time encountered the current Brax, he would definitely not have the strength to resist and would be instantly killed.

This Brax was clearly much stronger than the transformed man who also claimed to have the strength of a fourth-stage Internal Breath Realm!

“Fortunately, I haven’t been idle these few days. Otherwise, I would really have nowhere to cry if I was beaten home by this guy before the first assessment passed.”

Chu Nan smiled and took a deep breath. He stopped thinking, took a large step forward, and threw another punch.

Seeing Chu Nan’s punch, Brax and the surrounding crowd frowned.

Chu Nan’s punch was much stronger than the first one. It had more or less become decent, but it still looked extremely rough and was not much stronger than an entry-level martial artist.

The surrounding crowd could not help but feel puzzled.

Chu Nan had clearly used a decent fist technique in the martial arts competition earlier. The punch that he had changed his move earlier was also shocking, powerful, and had a calm bearing. Why did he have to use such a rough fist technique that was no different from a layman when he took the initiative to attack?

Brax was also puzzled, but he was still fighting Chu Nan in the arena and did not have the time to think too much. He only sneered and threw a punch back without holding back.

Seeing that his punch was aimed at the huge gap left by Chu Nan’s fist technique and was about to hit him, Chu Nan changed his move in time and threw another punch at Brax’s fist.

Boom!

A muffled explosion that was much louder than before spread throughout the entire arena, shaking the ears of the audience until they buzzed. The weaker martial artists, such as Chu Xiaoxi, could not help but cover their ears.

Then, everyone was surprised to discover that Chu Nan only took a step back this time. He stabilized his body and threw another punch at Brax.

This punch looked a little more decent than the previous two punches, but it was still not organized.

Brax threw a punch back, but Chu Nan changed his move again and blocked the punch without showing any weakness.

Boom! Boom! Boom! Boom!

Explosive sounds continuously sounded from their fists that collided, fully showing how intense the battle between Chu Nan and Brax was.

However, the surrounding crowd became more and more puzzled the more they looked. The doubts in their minds accumulated deeper and deeper.

What was Chu Nan doing?
