After Transmigrating Back, I Return to the Village to Plant a Moyun Vine

The Grand Fortune sent Chen Wanhe to another world to struggle for five years. At last, he saved enough for a ticket home. Back on Blue Star, he thought everything that had happened during his transmigration would vanish without a trace. But to his surprise, the System he'd worked alongside for five years defied its own basic rules to preserve his memories, and even gave him a tree. 【Chen Wanhe's Tree: All plants within its range receive bonus effects】 Its basic effects include accelerated growth, improved survival rates, increased yields, and better quality. It can also improve plants' ability to adapt to their environment, making them drought-resistant, acid-resistant, and salt- and alkali-tolerant... After upgrading, it can withstand temperatures as low as minus 120 degrees and endure heat up to 800 degrees? Is it trying to get him to grow potatoes on Mars? Heavens as my witness! All he wants is to grow a few things and help everyone earn a tiny bit of money. Wait, The System even sent a little gift across dimensions. And it's a seed. 【Cloud-Piercing Vine: A defensive plant. Once mature, it can be made into a small war machine】 !!!
