Long ago, Tai Sui had already reached Third Rank Peak. Later, after Chen Mobai achieved Nascent Soul Formation, he appreciated its hard work and contributions and gave it the opportunity to advance.
Now that Tai Sui has transformed in form, it's clearly at Rank-4.
In terms of level, it's equivalent to a Nascent Soul Cultivator.
Although without a cultivation method, its combat power isn't as strong as Zhou Shengqing, it can easily suppress Rank-3 demonic beasts and Golden Core Cultivators.
"How did it pass the Heavenly Tribulation?"
Chen Mobai motioned for Tai Sui to come over and checked its form after the transformation, to see if he could tailor a cultivation method for it.
"Reporting to master, it merely took one bout of heavenly thunder and passed with ease."
The answer came from Zhuo Ming, as Tai Sui, having just transformed, was still learning to speak and couldn't say much yet.
