Su Ping, with the help of the perspectives of the Spiritual Rats White and Grey,
was the first to remotely behold the mushroom cloud slowly rising above the Taoist temple.
Although this mushroom cloud wasn't as exaggerated as the special effects in movies, it certainly showcased the potency of the explosives.
The Taoist temple on the mountain had almost instantly turned to ruins the moment the mushroom cloud soared into the sky.
Many wooden structures caught fire, adding flames and black smoke to the mushroom cloud.
Su Ping was not surprised by the appearance of the mushroom cloud.
Given a sufficient quantity, even black gunpowder could create a mushroom cloud.
Not to mention that Su Ping had used the sweet gunpowder praised by many civilian military organizations.
Moreover, the explosion occurred in a relatively enclosed underground chamber, so with the right timing and location, such an effect was within reason.
