This was the Heaven Measuring Metal Ruler, and it had been forged by the Metal Element Saint all those years ago. It was a genuine Saint Tool!
The moment this ruler appeared, endless golden light descended. The great power of heaven and earth was also drawn, condensing the endless power of heaven and earth, which pressed down on the Heavenly Dao Flames.
If this Heavenly Dao Flames had not been weakened, then even the Saint Tool would not be able to suppress it. This was a terrifying flame that could burn a Saint to death in the first place.
However, the might of the Heavenly Dao Flames had already been weakened, so it was no match for the Saint Tool.
However, the Heavenly Dao Flames was still the Heavenly Dao Flames. Although the Heavenly Dao Flames could be suppressed, it wasn't so easily extinguished. It could only extinguish the flames bit by bit. This wasn't something that could be done in a short while, but would take at least eight to ten days, or even longer.
