Just like before, in the Jiazi formation, the power of the second-class Taoist soldiers was all bestowed on the Jiazi divine general, but because he himself was only level six, which was the peak of gold, he had not been able to reach the seventh level of returning to the void. As a result, even though the power lent to him by these Taoist soldiers was actually far beyond his reach, he himself had not reached that level, resulting in him being unable to exert the power of the seventh level of returning to the void.

Therefore, at this time, no matter how great the cost, he needed to gather a large amount of Yin energy on these Taoist soldiers, so that they could directly increase their strength to the seventh level.

Even at this time, Xu Luo did not continue to collect those ghosts on a large scale into the Ghost Gathering Banner, but directly killed them and harvested a large number of ghost beads.

Because at this time he needed to use the pure yang power in the Yin Soul Pearl to bless these gods and generals, so that they could improve their strength.

If they want to generate yang from yin and directly reach the level of returning to emptiness, they need to transform the yin energy in their bodies into yang energy, which requires a large amount of pure yang power for baptism.

If they were allowed to practice slowly on their own, it might take hundreds or even thousands of years to complete this process.

Because the practice of Taoist soldiers is itself a very difficult task and requires a lot of resources to consume, this is why ordinary people simply cannot afford to support Taoist soldiers.

But now with the Yin Soul Orbs, this process can be shortened greatly. As long as there are enough Hero Soul Orbs, this process can even be completed in an instant.

Xu Luo is extremely ambitious and wants to directly elevate all of his Taoist soldiers and generals to a level above Return to Void.

Therefore, although the number of Yin Hun Pearls he collected at this time was not small, it was obvious that there was no way to improve all of them. So at this time he was just collecting them silently, accumulating the number of Yin Hun Pearls in his hands little by little, waiting for the day when there were enough, and then he would improve the strength of these generals under his command at once.
