After summer vacation, Lin Xiao found a summer job to earn money.

But when he was taken to his workplace, he was stunned.

The workplace is actually on an alien battlefield, fighting against insectoid creatures.

Beneath the crimson sky lies an endless alien desert, filled with roaring insectoid creatures, tattered mechs, and enraged mercenaries.

In order to make money, Lin Xiao had no choice but to join the war.

Two months later, the federal order was issued.

"Four-star mercenary Lin Xiao, your outstanding tactical talent and courage have earned you everyone's recognition. You are hereby appointed as the commander of the First Battle Group!"

Lin Xiao stood at attention and saluted, but his tone was full of apology:

"I appreciate the federal government's support, but I cannot accept this appointment."

The commander was taken aback: "Reason?"

Lin Xiao said helplessly, "Because I have to go back to school."
