What Old Tang mentioned about verification naturally had to do with Xiaoxuan.
And when it comes to conducting experiments, the Thousand Mechanism Pavilion is professional at it now.
Various venues and equipment are all fully available, and safety is well guaranteed, too.
After all, half of the things developed by the Thousand Mechanism Pavilion tend to explode.
After rigorous repeated comparative experiments, Zhang Ze and the others discovered several characteristics.
First, activating Xiaoxuan's intelligence only requires two Big Heads.
Second, the Big Head's intelligence only increases after Xiaoxuan becomes smarter.
Third, the Big Head doesn't need to be too close to Xiaoxuan; they just need to be within a 500-meter radius centered on Xiaoxuan for the effect to occur, but it can't be blocked by a spatial magical artifact.
Fourth, after Xiaoxuan and the Big Heads revert to their innocent states, they still retain the memories from when they became smarter.
