Normally, cultivating a second-grade spiritual plant to maturity takes one or two years, sometimes even longer. Lu Xuan, however, lacked the patience to wait for the Yellow Cloud Mushrooms to mature naturally. Thus, he decided to use the Green Wood Source Energy to speed up the process.
Although Green Wood Source Energy was extremely rare, Lu Xuan now had the Spirit-Absorbing Grass Pearl, which he had obtained from the white light orb of the Hidden Origin Grass. If he consumed too much Green Wood Source Energy, he could replenish it by absorbing the Spirit-Absorbing Grass Pearl. Since the Yellow Cloud Mushroom was only a second-grade spiritual plant, the amount of Green Wood Source Energy required wouldn’t be excessive. With this in mind, Lu Xuan felt confident in using it liberally.
