Ou Yenuo And Ou Chen's Past, Blazing Flame Mountain's Origin, Someone Is Asking For Trouble

"Heavenly Thunder Weapon Quenching Technique? A forbidden technique?"

Chu Kuangren was surprised by the book that he was reading.

Ou Yenuo noticed the book in his hand. "This technique is a forbidden technique from my master. It remains a theory because it's too dangerous. No one has dared to test it out."

His explanation intrigued Chu Kuangren even more, and the latter continued reading. 

Quenching was a necessary step in forging.

The energy or material used for quenching varied from many mystical options.

Some used the coldest ice, some used the hottest flame, and some used the clearest water.

That Heavenly Thunder Weapon Quenching Technique, as its name suggested, required the heavenly thunder, which was the lightning bolts from the Heavenly Tribulation!

The stronger the Heavenly Tribulation, the better, but that was not the most dangerous step.
