Jiang He might have transmigrated to a world of Qi and martial arts, but the System that he got only provided him with... seeds. 
"Hold on, System. Aren't these just... peas? Not only are they inedible, but I'm supposed to throw them far, far away?" 

Everybody is Kung Fu Fighting, While I Started a Farm

In his farm, a crisp System Notification jingled in Jiang He's head when he reached out to pluck a jadelike superior-grade spirit stone from a spirit stone tree.

"One superior-grade spirit stone would have earned me a thousand Farm Points before my farm leveled up, but it's now just one hundred… even in total, the entire spirit stone tree would only earn me ten thousand points."

Of the nine factions, only the Unbounded Demon Sect compensated Jiang He with one demi-immortal item, three premium-grade sage items, and two thousand superior-grade spirit stones. The other seven factions each paid him one demi-immortal item, three premium-grade sage items, and one thousand superior-grade spirit stones, making it a total of eight demi-immortal items, twenty-four premium-grade sage items, and nine thousand superior-grade spirit stones.
