It used the power of the copper box fragment.
Just as Wang Dadong was being swept toward the seabed by the Great Squid King, he used the copper box fragment again.
But he had to use the power of the copper box fragment as little as possible, so he didn't directly let the copper box fragment save him; instead, he hoped the copper box fragment would give him some good luck.
Thus, he was able to float to the surface near the submarine and was coincidentally carried to the two women by passing dolphins.
This wish was definitely much smaller than asking the copper box fragment to directly save him.
However, even if it was smaller, it was certainly with side effects.
When he inhaled Ghost Incense, he had already used the copper box fragment once, and now it hasn't been long, and he used it again.
The side effects of the fragment might appear very soon.
But compared to dying, what's bearing some side effects?
