Gu Ding's decision to challenge Senior was not made on a whim. When he was defeated on Constlac, he made up his mind to defeat Senior the next time they met. He did not expect the opportunity to come so soon.

Gu Ding did not dare to slack off in the face of Senior. After all, he and Liliath had been suppressed by Senior the last time they fought together. If Senior had not stopped in time, he would have been imprisoned in the Federation Prison.

Ultimate Arts Level 7 and Rage Attack Level 2 were activated at the same time. Gu Ding stepped forward with a Silent Step and instantly appeared in front of Senior. He threw a Steel Fist with all his might and did not hold back.

Gu Ding's figure was slightly thin in front of Senior, who was nearly two meters tall. However, no one dared to doubt his combat effectiveness, including Senior himself. Senior had seen Gu Ding's strange martial arts countless times in videos. He knew how terrifying Gu Ding's punch was. Defense was not the best choice against such a powerful attack. Senior chose to attack. He turned his palm into a knife, and his palm, which was twice the size of Gu Ding's, swung out like a sharp blade.

Fist against palm!

When Senior's palm, which had turned into a knife, collided with Gu Ding's fist, the sound of metal clashing could be heard. A huge force came from his palm, and he immediately retreated. He was a little shocked. Generally speaking, his special ability, Blade, could cause damage to his opponent even when their strength exceeded his. However, the collision with Gu Ding just now made him realize that Gu Ding's martial arts not only had a strong amplification effect on his attack, but it also had a terrifying effect on his defense. It made Gu Ding's body look like it was made of gold and iron.

This special effect was naturally brought about by Righteous Body. Under Ultimate Arts Level 7, Righteous Body had a tenfold increase in defense and a special effect of hardening the skin. Ultimate Arts was a comprehensive martial arts that had no flaws in both attack and defense.

Gu Ding naturally would not give up on chasing after Senior. He stepped forward with a Silent Step again, and with a flash of his body, he appeared in front of Senior again. Gu Ding had chosen to attack head-on both times. He wanted to suppress his opponent with his strength.

Senior activated his Defense Level 2 and swung his hand again, aiming for Gu Ding's neck. He was planning to exchange blows with Gu Ding. His Cell Index had exceeded the limit of a Rank 7 Gene Body. It was thirteen thousand points. After activating Level 2 Defense, his defense would double. The collision between the two of them allowed him to determine that Gu Ding's attack was close to twenty thousand points of Cell Index strength. However, it did not exceed twenty thousand points. Therefore, Gu Ding would not be able to pose a threat to his Level 2 defense for the time being.

Gu Ding was a little surprised by Senior's method of fighting with his injuries. However, he was not afraid. Whether it was Ultimate Arts, Rage Attack, or Combat Armor, the increase in defense and attack power was the same. With Gu Ding's current Cell Index of 320 points, the ten-fold increase from Ultimate Arts, the three-fold increase from Rage Attack, and the two-fold increase from Combat Armor, his defense and attack power were comparable to a martial arts practitioner with a Cell Index of 19,200 points. He was still a distance away from Senior's 26,000 Defense Points after activating Level 2 Defense. However, Senior's Attack Power was no match for his.

However, the neck was a vital part of the human body. Even though Gu Ding did not intend to defend himself, he still stepped aside and dodged the attack. Due to the angle of the attack, his Steel Fist instantly changed to Terminating Finger and hit Senior's heart on the left side of his chest.

Senior's moves were not as flexible as Gu Ding's. Due to Gu Ding's dodge, his knifehand landed on Gu Ding's left shoulder blade and only left a shallow scratch on Gu Ding's body. However, Gu Ding's Terminating Finger had hit him squarely in the heart. Although his defense was strong enough to block Gu Ding's attack, the impact on his chest still caused his heart to stop abruptly, and he felt dizzy. He immediately retreated, worried that Gu Ding would continue to attack him. While he was dizzy, he would not be able to fight back.

Gu Ding was a little surprised to see that Senior could still move freely after being hit by his Terminating Finger. Terminating Finger was a point-to-point attack. When the attack power was the same, it was more destructive than other moves. Moreover, Gu Ding had attacked Senior's heart with the purpose of making him lose his combat effectiveness. However, he did not expect Senior to be so tenacious that he could withstand the attack and did not seem to suffer much damage. For a Rank-7 Gene Body, Gu Ding's attack just now was almost fatal.

"Don't forget, his Cell Index has exceeded the limit of an ordinary Rank-7 Gene Body. Moreover, he has a Level 2 defense ability, which can double his defense. If you don't use Damage Stacking, your attack will cause very limited damage to him, "Neptune reminded Gu Ding.

Only then did Gu Ding realize that he had read Senior's information before, but Gu Ding had overlooked this point because Senior did not show his full strength in the last battle. He did not use Damage Stacking earlier because he was worried that he would accidentally kill Senior. After all, an ordinary Rank-7 Gene Body only had a Cell Index of ten thousand points at most. Gu Ding's attack of nearly twenty thousand points was lethal enough. If he used Damage Stacking, there was a high chance that he would accidentally kill Senior.

After knowing that Senior had a Level 2 defense ability, Gu Ding was slightly relieved. He immediately activated Damage Stacking and chased after Senior.

For the third time, he chose to attack head-on. Steel Fist violently blasted out with the force of breaking the wind.

The chaotic heartbeat in Senior's chest had not calmed down yet. When he saw Gu Ding rushing toward him, he dared not fight head-on. However, his body was not as agile as Gu Ding's, so he could not avoid it. In desperation, he could only overlap his arms and forcefully withstand Gu Ding's Steel Fist to prevent Gu Ding's attack from hurting his internal organs.

The punch landed, and the curse effect of Damage Stacking was also planted. Senior was blasted away by the punch. Although his arms were numb, his body was not affected much. With the help of the recoil from the punch, his figure retreated again. He quickly adjusted his breathing, trying to get his heartbeat back to normal as soon as possible.

However, Gu Ding obviously did not intend to stop there. He suddenly exerted force in his legs, and the bricks under his feet instantly shattered. His figure was like a swift cheetah as he sprinted forward and appeared in front of Senior again in an instant.

He swung his fist again. It was still Steel Fist, and there was nothing fancy about it. This was the simplest attack, but it was also the most violent attack.

Senior, who had not yet stabilized his body, once again folded his arms. He wanted to defend against the blow again and buy more time for his heart to beat wildly. However, this time, he made a wrong decision.

After the damage was stacked, Gu Ding's fist force had reached a terrifying level. The moment it collided with Senior's arms, it crushed the bones in his opponent's arms as easily as crushing dry weeds and smashing rotten wood. The tremendous force slammed into Senior's chest and broke eight of his ribs. Senior's internal organs also suffered a strong shock, and his heart stopped beating again at that moment. A stream of bright red blood spurted out of his mouth, and his body flew backward weakly. Then, he fell heavily to the ground and completely lost consciousness.

The onlookers had thought that the battle would last longer. Based on the previous fight between the two, neither of them had been able to break the other's defense, and the damage done to the other was very limited. However, the scene that had just happened was something that no one except Lilliath and Biggie had expected.

After checking Senior's injury and finding that Senior's heartbeat was very weak, Gu Ding immediately asked Neptune to dial the emergency number.

"Hello, is this the emergency center? There's an Army senior colonel at the port who's seriously injured. Please come over as soon as possible, he won't be able to hold on for long. " After hanging up the call, Gu Ding took out a bottle of E-grade cell repair agent, pinched open Senior's mouth, and poured it in.

Once again, the scene was recorded on video and posted on Skynet.

After Senior was carried into the ambulance, Gu Ding left the port with Lilliath and Biggie, rented a car, and rushed to the auction venue.
