Tang Li pulled Qi Yihan to the backyard because she wanted him to see the herbs she planted in the backyard.
Ever since they moved in, she had specially turned a piece of land into a garden for the herbs and used a Spirit Gathering Formation and Concealing Formation to keep them from being seen.
As long as Tang Li did not activate the formation, no one could see what was inside.
When he saw the herbs in front of him, Qi Yihan was a little surprised. "These herbs look good."
"Not really." Tang Li was still not satisfied. "Although I used a Spirit Gathering Formation here, the place is too small and the formation is too small. After the island's infrastructure is built, I'll set up a larger Spirit Gathering Formation on it and plant all the herbs we collected. When these herbs absorb the spiritual energy, they will slowly evolve into spiritual objects."
