After Grenade-Throwing Senior Immortal had bulldozed the garden behind the villa back then, he had built a simple sunroom. In it, he had planted different types of hybrid spirit grass which he used in his research.
Since he was a kid, his dream had always been to be the father of hybrid spirit grass in the cultivation world.
He had been trying to develop a kind of poor man's spirit grass that would be easy to plant and could rapidly gather the spirit energy of heaven and earth, which could be used by children from poor areas who had no cultivation resources.
Long before he had moved to Wenxian Garden, Grenade-Throwing Senior Immortal had already been busy with this research.
Unfortunately, there were a lot of technical issues with hybrid spirit grass, and two months ago, he had become stuck in a bottleneck in his research. Since then, he hadn't made any further breakthroughs.
