Mu Hongxi also mentioned his unverifiable speculations in the book.

Mu Hongxi mentioned that he believes the Blood Jade Space might be able to upgrade indefinitely. However, it requires "merit points." As long as one continuously increases their "merit points," the Blood Jade Space can continuously upgrade, but Mu Hongxi doesn't know to what extent it will upgrade to its limit.

He also mentioned that "merit points" become increasingly difficult to obtain as time goes on, especially during times of peace and prosperity, when merit points are scarce and opportunities to perform great acts of merit are very limited.

Unless it is a natural disaster or a chaotic time, it is easier to gain great merit by saving people or the world.

Mu Hongxi guessed that this was why the Blood Jade Space always opened when a major disaster was about to occur.

Based on Mu Hongxi's guess, Mu Qingyu felt that what he said made sense.

Mu Hongxi's greatest contributions at that time were building bridges and roads to develop his hometown and helping the poor and needy. Apart from that, in times of peace and prosperity, he couldn't accomplish anything greater.

But for Mu Qingyu, zombies wreak havoc on the world, so killing zombies is protecting the world and its living people, which is naturally a meritorious deed.

In this apocalyptic world, with countless zombies everywhere, Mu Qingyu's merit points indeed increased rapidly as she killed zombies!

For the Blood Jade Space, the apocalypse was actually the best opportunity for it to upgrade.

This blood jade space and its host are somewhat interdependent.

This made Mu Qingyu quite excited—there are so many zombies in the world, if she gradually eliminates them all, what kind of incredible existence will the space become?

It's important to know that the upgrades of the host and the space are synchronized.

Mu Qingyu kills zombies to upgrade her space, and the space in turn upgrades Mu Qingyu's physical abilities and superpowers, complementing each other to become stronger!

This realization ignited a surge of excitement in Mu Qingyu! Kill zombies! We must kill zombies! She was also eagerly anticipating where the space upgrade would end!

However, Mu Qingyu also found paper and pen. As the third member of the Mu family to open the Blood Jade Space Bracelet, she, like her two ancestors, recorded her identity and the opportunity to enter the Blood Jade Space on the blank page after Mu Hongxi.
