Chen Mo had many ways to kill Barricade, but his goal was not simply to eliminate a Decepticon. He regarded his opponent as a sparring partner, intending to improve his control over his strength through battle.
Nothing could improve his mastery of his own power faster than actual combat!
Therefore, Chen Mo did not draw the indestructible King's Sword. Instead, he put on the Iron Man suit, transformed into an iron warrior, and engaged Barricade head-on in close combat, relying on the suit's powerful defense and mobility!
As for why he did not simply fight with his own strength, it was because Chen Mo was not yet powerful enough to directly withstand a Transformer with his flesh and blood!
Although his incredible speed, teleportation, telekinesis, and other abilities could keep him undefeated—and even allow him to kill Barricade—they went against his original intention of training in close combat.
Chen Mo's physical abilities had now reached ten times those of an ordinary person, but against a massive Transformer, he was still at an absolute disadvantage in terms of strength. His body was not tough enough to withstand a Transformer's attacks either. Chen Mo had no desire to test just how powerful his healing ability had become; he did not want to end up in such a miserable state.
The Iron Man suit, however, was currently the most suitable piece of supporting equipment!
Powered by machinery, the Iron Man suit's strength already exceeded Chen Mo's own physical power. Combined with his formidable strength, twelve times that of an ordinary person after Riot's enhancement, it was barely enough to contend with the tremendous power of a massive Transformer.
Furthermore, the Iron Man suit forged from Adamantium possessed incredibly powerful defenses, enough to withstand all kinds of Barricade's attacks and ensure Chen Mo's safety!
