Zhou Tong had a lot to share with Zhou Heng, mostly about some interesting matters regarding the Zhou Family, especially Zhou Yanran. Clearly, Zhou Tong harbored deep "resentments" toward this clan sister, and he was quite fearful of her, involuntarily shuddering whenever her name came up.
To scare the Little Overlord like that, could Zhou Yanran actually be a witch?
Actually, instilling fear in someone doesn't always require fierceness, just look at Huo Tian. Doesn't Black Donkey act like a mouse when he sees a cat around her?
Zhou Tong specifically discussed with Zhou Heng the precautions needed for advancing to the Sunshine King, a breakthrough to a Great Realm, signifying a qualitative leap from Bright Moon to Red Sun.
The two talked for at least four or five hours before Zhou Tong finally escorted Zhou Heng back to the starship of the Lian Family. He didn't disembark and directly set off, like Zhou Heng, he too preferred to avoid social interactions.
