Zhang Yan stopped laughing and stared at Long Yu seriously, "Actually I didn't fight with all my strength, too. This time we'll see who is stronger."

Before the sound of his voice had died away, an overwhelming power burst out from his body. The disciples of Green Gang closer to Zhang Yan were scared by his momentum and took a few steps back, but Long Yu just snorted and also released strong power to play against him.

Five spiritual energy cyclones were rotating fast in Zhang Yan's Dantian and the spiritual energy inside his body was transferred from his Dantian to his arm quickly. Soon he slammed his fist into Long Yu's chest with all his strength.

Long Yu also spared no effort to mobilize all of his spiritual energy and rose to the challenge. Two fists collided with a "bang", which was like two rushing elephants colliding with each other. The surrounding disciples were frightened out of their wits by the deadly impact.

However, the two people didn't get hurt at all after one strike. They kept fighting with a dozen strikes, focusing on no technique or skill but physical strength. They were like two giant beasts in a hand-to-hand combat, which shocked the bystanders.

Even Hong Yuan stared with astonishment. He didn't expect that Long Yu had made so great progress in cultivation strength. If he got punched, he would be badly hurt. What shocked him more was Zhang Yan, a newcomer of outer court disciple. He could be matched with Long Yu in physical strength and even prevailed. It was a miracle.

After giving dozens of punches, Zhang Yan became more energetic and excited as if he was a born fighter. Long Yu, on the contrary, tried not to be outdone by Zhang Yan but soon he realized how terrific Zhang Yan was. He thought he was inferior to the boy in physical strength for the first time.

After landing another punch, Long Yu obviously felt his lack of physical strength. His strength didn't reduce at all but Zhang Yan's strength increased. It casted Long Yu into doubt on Zhang Yan's increasing power, "Does he fight with not all his strength?"

Long Yu understood that he must be defeated in three moves if he kept fighting in the old way, so he was forced to make a kill shot. He changed his hand move from clenched fist to open palm. Meanwhile, the spiritual energy inside his body was running in a special way. Immediately, he gave a punch to Zhang Yan in the fist at a lightning speed.

When Zhang Yan's fist hit against Long Yu's palm, he felt Long Yu's strength raised by two levels instantly. Unexpectedly, he was thrown away by the punch for one meter away until he stood firm. His right arm was almost broken by the strike.

Long Yu lost his momentum after giving the punch, which demonstrated that he had expended lots of spiritual energy on this move.

Zhang Yan opened his eyes wide and asked uncertainly, "Is it martial skill?"

"Yes!" Long Yu answered haughtily with his head thrown back, "It is the superior martial skill of human level, Great Strength Vajra Palm. You should take pride in forcing me to use martial skill. I have never applied it to any fight with outer court disciples except you."

"Martial skill!"

Long Yu's answer astonished other disciples again. Martial Skill, created by some benevolent masters of martial community, was a way to use cultivation. It was similar to martial technique in levels but rarer than the latter.

Martial technique of human level was widely available in the market if you had enough power and money, however, the lowest martial skill of human level was priceless even outer court disciples of the saint martial land, Qingyuan School, had no access to it. In the school, only inter court disciples were qualified for the cultivation of martial skill.

Zhang Yan didn't anticipate that an outer court disciple had cultivated martial skill even of superior human level. It was unbelievable! However, the more advanced the martial skill was, the more spiritual energy a cultivator had to spend. It seemed that Long Yu couldn't give more punches like the first one.

Waving his arms, Zhang Yan believed that he could accept more punches. As soon as Long Yu was drained of his spiritual energy by launching attacks, Zhang Yan would win. Therefore, with a purpose, he was squaring off, really to fight.

Long Yu stared at Zhang Yan, "You got spine. Why did you fight with me after knowing about my martial skill?"

Zhang Yan snorted, "So what? Is martial skill unrivaled? Without enough cultivation and perception, how effective your martial skill would be? How many punches you can land just like the first one?"
