Battle for Mars

He China chose the difficult mode when he was reincarnated. As an orphan, he lived with his grandmother. He finally graduated from college and started working, but he could not afford a house due to high housing prices and his girlfriend left him. Moreover, because of unfair compensation from the developer, He China and his grandmother were brutally murdered by 11. When He Zhongguo was reborn, He Zhongguo suddenly found himself on Mars, with a biological robot body, carrying many of the world's most advanced technological capabilities, and discovered that Mars was still an era of cold weapons in feudal society. He Zhongguo was glad that he finally chose the easy mode for this reincarnation. When he discovered that magic and fighting spirit were flying everywhere on Mars, physical training and secret techniques emerged one after another, and conspiracies and tricks were endless, He Zhongguo discovered that in this life, he had chosen a super difficult mode. Unwilling to be reconciled, He Zhongguo created hot weapons and launched a world war involving magic and technology, hot weapons and cold weapons, and finally unified Mars.
