Marvel City? No, It's Super God!

On Christmas Eve in Bern, Su Wei finds himself transported both physically and spiritually into the Marvel world, waking up beside the corpse of his doppelganger who had just died. As the half-brother of the villain Killian and the marginalized second shareholder of A.I.M., he absorbs the residual soul to gain memories, but he is by no means as cowardly and easily bullied as the original. He is not a savior hero, nor will he repeat the villain's mistakes, but rather aims to be a ruthless leader with principles, rewriting the predetermined fate with his own hands. The 'Myriad Heavens Black Technology System' unexpectedly binds to him, unlocking countless creations in the tech mall, with reputation points becoming the capital for his rise. T-virus serum, mind-control chips, high-frequency blades, intelligent medical robots... He selects top-tier artifacts, using technology as a blade to carve a path to survival in the cracks between capital and power. Unknown to all, deep within his consciousness lies a portal that the system cannot detect, visible only to the soul, fueled by reputation, allowing free travel between myriad worlds. On the surface, he is a tech upstart rising through black technology and the hidden helmsman of A.I.M.; in the shadows, he is a lone traveler absorbing the essence of countless worlds. One reputation, dual use—while others are still fighting for Earth's hegemony, he has already set his sights on the endless star sea. This Christmas Eve marks the end of the original, but the beginning of the legend of the ruthless leader Su Wei. — Description from novelcodex.org
