Although it took four-fifths of his Immortal power to collect the Immortal blade, Peter Brown was extremely satisfied. With this Immortal blade, Peter believed that as long as he wielded it, his combat power would soar dramatically. Of course, Peter wouldn't use the Immortal blade lightly since it consumed too much Immortal power.
In the Immortal Realm, where Immortal power was abundant, using the blade wouldn't be an issue as he could constantly replenish his power. However, the Cultivation World was entirely different; there wasn't much Immortal power here, and using a little meant there was less available. Peter felt that his current Immortal power would be enough for only about two or three swings of the blade in the Cultivation World.
Riding on the Immortal blade, Peter flew through the sky. Although it consumed some of his Immortal power, the feeling was incredible.
Immortal tomb!
