Of course, these gains are not the most important.
The coolest thing is!
The Pure Fire Blood Lotus has already taken root in the Tao Ancestor Blood River, thriving with life, and can continuously absorb various nutrients to nourish itself and grow robustly.
This means that even if Fang Zhixing does nothing, a vast amount of merit will continuously pour into his body, causing his cultivation to rise every moment.
Of course!
His transformation from a Tribulation Immortal to a Merit Immortal comes with losses alongside gains.
For example, before, he had the Blood Heavenly Tyrant Demon Body, allowing him to gain memories and skills of cultivation from others by consuming their blood.
Now that he is a Merit Immortal, possessing the Pure Fire Blood Lotus Merit Golden Body, he no longer needs blood, and those capabilities naturally disappear.
Fang Zhixing is not particularly concerned about this.
