It would take a long time to use the spiritual root seed to control a Nascent Soul creature and completely control it.
It was even harder to control a monster of this level. Currently, he had never succeeded.
Previously, in the deep sea near the Armored Troll Island, Jiang Li had risked his own injuries to capture an Armored Troll equivalent to the Soul Formation realm.
The other party had been heavily injured by him and was on the verge of death, and he had been locked in the coffin since then. With Jiang Li's personality, he naturally would not waste anything useful.
During this period of time, he had been using the spiritual root seed of the Nine Nether clone to try and control this guy to turn over a new leaf.
Unfortunately, no matter how he tried, he failed.
