Morbius' New Spirit Lock!

Besides Forbidden Growth, Lin Yuan was more interested in Peak Sturdiness.

Although it required an increasing amount of spirit qi, vitality, and wood-elemental energy to nurture the Perfect Touch Wisteria, using an increasing number of resources could be used to make the vines sturdier and stronger.

This was a low-cost method for people who did not lack resources.

A spirit qi professional had a limit to the number of feys he could contract. Hence, only by focusing on unlocking the potential of every fey could they increase their power to the greatest extent.

This was the path that Lin Yuan was going down.

Liu Jie was confused when he saw the way Lin Yuan's eyes were shining as he stared at the Perfect Touch Wisteria, but Yi Huailong managed to guess what was going through Lin Yuan's head.
