He literally forces WonPil to leave his job and to come with him every day, for some trainings the same way as what he made XinLan do, when he was a child. At least he knows for sure that that works to prevent the formation and accumulation of negative energy inside of him, which is what leads to catastrophic events.
In WonPil's case, that energy accumulated wildly during the time in jail and his completely dissatisfying job is not a good way to unleash his energy.

Lani takes WonPil to train in his house, so that they have plenty of space outside, don't risk to harm others and they can use the gravity room,.if needed.
Doing those things with WonPil unavoidably makes Lani kind of fond of him, since he connects WonPil with XinLan.

As promised, as soon as he comes across LiHao again, he convinces him to meet him at the stand the next day to see some new products in preview, but actually warns ZhongLi so that he can go to meet him.

Convinced by She'er's optimism, he decides to try to meet the King for real and hear what he has to say. After all, if he won't like the response, he can simply disappear. That's the positive side to live in a totally isolated and remote house.

He closes his stand and follows She'er to the palace when he goes, so that he won't have to book an appointment and possibly have to wait for his turn, he prefers to be abuse of people's hospitality and kindness!!

He waits outside the throne room while She'er speaks to the king himself, just waiting for his turn.

After returning home, he can determine that Cyno's conditions are stable enough for him to return to the others. Lani doesn't really fancy to have people around himself and his son, even if Cyno is from another world and would have no way to mess up with XinLan, thus he is very eager to send the patient off.

Lani teleports Cyno back to TiHao's fortress and just leaves right away. He has given the General the medicines he still needs to take and some instructions on how to ensure to recover quickly.
Unlike ever seen before, Cyno is wearing some properly covering, thick clothes and boots, that Lani had to provide to avoid the patient to fall back sick two hours after dismissing him.

After some time, ZhongLi has to go to warn Lani that due to the new developments, the visit to Lianxi is going to last longer than they had initially planned.
Since Lani has to return to his son, he leaves a portal open inside of Chan's house, warning ZhongLi that it will stay open till morning and then it will shut on its own. He also warns TiHao about the delay, so that nobody will get worried.

With that done, ZhongLi is free to wander around on his own for a bit.
