His Majesty's Bride. - Chapter 32: State of Emergency.

A skilled thief gets a system in an Alternate Wizarding World. The system seems useless in the beginning since he hasn’t unlocked any features. But…

[The very first feature of the System has been unlocked.]

[Congratulations. You’ve unlocked the class feature. Due to your existing skills and experience, you have gained the Special Class "Arcane Thief" as your starting class. There’s nothing an Arcane Thief can’t steal. The more you steal, the more your Class will progress.]

[The fields of expertise include:

— Stealth Magic
— Wards
— Traps
— Enchantment
— Pickpocketing
— Knife/Short-Sword Wielding]

Wait…this is just the first feature?

Zhou Qi was reborn countless times before the end.

Every time, it doesn’t end well.

Monster invasion, natural disaster baptism, twisted rules, world destruction…

He is familiar with the survival laws of all environments, he is the doomsday walker, the lonely savior.

However, it is also a poor worm trapped in place.

What is the truth of the end? Are human struggles really meaningless? What does his existence mean?

… Zhou Qi thought about these questions and woke up again from his dream.

When the strangeness came, he made all preparations numbly.

but–

The end did not come this time.
