Refining Weapons

With that supreme Hongmeng creation energy, Yin Lan turned back time and returned to 48 million years ago. At this time, in the Shanlan Continent, spiritual power cultivation only had a history of ten thousand years. There were no spiritual techniques to increase the speed of cultivation and avoid the risks of cultivation. There were no attribute transformation techniques suitable for different people, and there were no powerful taboo spiritual techniques, fusion spiritual techniques, or sacrificial spiritual techniques. The level of weapon refining at this time was still in the Bronze Age. There were no spiritual power-driven vehicles, no impact cannons, and even a portable communicator had to be purchased at an exorbitant price. As for the originator of alchemy, he was still sprouting in his mother's womb... In this year of his previous life, Yin Lan was sixteen years old. On this day in his previous life, his father was beaten to death and one of his legs was broken. That kind-hearted girl who was forever sealed in the depths of her memory was also forced to swallow the potent glycerin oil, and then died of the poison. She withered and withered in her most beautiful years... After rebirth, he doesn't want any regrets! Book club group: 458829120
