A module full of bugs
(Note: This chal has remote instance)
Show me your runes.

Hint:
1. No intended vulnerability in the bzImage/kernel, please exploit the userspace chal binary.
2. As the challenge's name implies, you need to focus on the `syscall` aka rune in this challenge. Find a way to **weaken the dark dragon's power** once your character becomes strong enough.
3. All syscall numbers(系统调用号) used in the intended solution are under 200 and relatively well used.
Before working on the real-world challenge, let's warm up first. Write your C program to read /flag. Please have a look at `README` in the attachment first.

Have you ever PWNED a real-world project? Write your mips assembly to get /flag. Please have a look at `README` in the attachment first.
