When Li Jing opened his eyes, he became Li Jinglong during the Battle of Jingnan. The 500,000-strong army had just been defeated by Zhu Di.
Emperor Jianwen's death edict had arrived outside the tent. He touched the blueprint of the flintlock gun in his arms and smiled bitterly: "Will you be sent to hell if you travel through time?"
"The Universal Military Industry System is activated." A cold mechanical voice sounded, "It has been detected that the host is in a desperate situation. Gift package for beginners: primary gunpowder improvement technology."
That night he blew up Zhu Di's granary and used homemade grenades to drive back his pursuers.
Three months later, at the Baigouhe battlefield, Zhu Di looked at the "Shenji Battalion" arrayed opposite and was confused: "Why can Li Jinglong's fire blunderbuss fire continuously?"
What made him collapse even more was behind - in the telescope, Li Jinglong was smiling at Yan Jun: "His Royal Highness, would you like to taste the taste of depleted uranium armor-piercing bullets?"
