It must be known that Lu Shutang is not only Zou Tianjin's nephew but also He Kao's schoolmate and friend.
Due to his work, He Kao happens to have access to the Huish Stone Trading Group and is involved in the Huishishi Brand project collaboration, which makes him the key figure connecting all these clues due to his understanding of the company's situation.
As for whether He Kao himself has the ability to break the sealed restrictions, it doesn't matter as long as he can find such an expert.
In that scenario, the Ancestral Hall would probably have to investigate He Kao and the "mastermind" related to him. Many of his secrets might be exposed, and even if they weren't, there would be much he couldn't do anymore.
But none of this happened.
Luckily, Lan Jiwan's discovery meant that He Kao became the first person to notice something wrong with Shi Yun Road on the surface, thereby preventing the conspiracy and redirecting the Ancestral Hall's investigation focus overseas.
