So that earlier line about summoning a dimensional creature was wrong.

The Mysterious Phone classifies it as a separate grade from Mythical. You can see this with Banana Fairy's Terror stat window.in 1075.

Where was it stated there are only ten slots for the ranking?

One only gets pushed out of the rankings if they get kicked out of the top 100, not when someone surpasses them. In previous cube battles, one could lose their position from being challenged, but that feature is not available in this one. The positions that would have "Zhou" in the name would be Zhou's Weakest Disciple (Ming Xiu), Zhou's Disciple Feng Qiuyan, Zhou's Disciple Qin Zhen, Zhou Wen's Brother (Zhong Ziya), Zhou Wen's Eldest Brother (Liu Yun), and Zhou Wen.

He needed to get a dimensional creature, not a Companion Beast. The goal was to extract physical materials from the bad luck creature to make a Mythical Serum for Wang Chan. You cannot do that with a Companion Beast, as they are primarily composed of Essence Energy.

What?

The person who owed him ten companion eggs was Irjarr, not Lucas. Lucas went to go retrieve the reward, but got caught up in a battle with Henry Cape. Soon after, Medusa broke out and the city became chaotic. Zhou Wen went to go hunt her down and left the day after.

Lance, the guy who used energy skills like a fighting game combo, was pretty friendly with him. Zhou Wen does not have zero friends in the Six Hero Families.

Neonate is in her name, which means child. It makes sense that she is small.

It's certainly true that most Companion Beasts are fairly unintelligent. It's even remarked upon a bit that some perform worse than the dimensional creatures they came from. Evolvables, or mythicals, tend to be more intelligent and not as obedient. The Tiger Soul General was always weird even before becoming evolvable, but that's probably due to the Mysterious Phone's fusion powers.
