Shoot once, change places—that's what Lin Fan had in mind. The so-called guerrilla tactics were the fruit of countless martyrs' experiments.
[Chaos Secret Realm Accumulation: Two thousand years of mana.]
"Huh?"
A single opening of the Secret Realm draws in nearly a hundred Immortals, yet it only accumulates two thousand years of mana.
And these two thousand years of mana are already the result after subtracting what the Realm itself consumes to operate.
Sigh!
This was a failed experiment. If it had been better planned beforehand, the harvest wouldn't have been so small. At the very least, it should've yielded four to five thousand years of mana.
Of course, part of the reason was also that no prodigies had entered. If there were prodigies, the mana emitted during their battles would be far more terrifying. But this Secret Realm was so obscure, and the Immortal Treasures inside were sparse; the truly valuable ones, he was reluctant to place inside.
