Zhao Yi observed by the Blue Jelly Swamp for several days, ensuring the Blue Crystal Radio operated normally, and after confirming there were no abnormalities in the reusable production molds, he set off back to the capital.

Linglong was resting, and upon seeing Zhao Yi return, her eyes lit up immediately.
"Your Highness, you've finally returned!"
Seeing Linglong's overjoyed expression, Zhao Yi asked curiously, "What happened?"
He remembered that when he left, Linglong was delighted to finally have a break, happy enough to wish Zhao Yi would stay outside longer.
In just a few days, Linglong's attitude had completely reversed, which was quite strange.
