Accidents always happen inadvertently.
Yu Taixu had totally underestimated Wugu Hou's power. Due to the huge gap between their ranks, even though Yu Taixu had a Supreme Fairy Weapon, he still lacked the strength to fight back. Similarly, although the Pool of Thunder Tribulation was a Heavenly Fairy Weapon, Wugu Hou's power was too strong for it to confront him alone. Due to these factors, a united front was the best solution.
If the Pool of Thunder Tribulation, a Heavenly Fairy Weapon, could successfully combine with the Great Constellation Palace, it would be possible to use up to eighty percent of the original power from the Great Constellation Palace in an instant. Although it could only strike once, that would be enough.
