C250 Self-digging Extra This Chapter Is Free of Charge

Dear Rachel:

When you see this letter, I should be in the middle of a mission.

If nothing unexpected happens, this letter will be given to you by Ning Hai.

Ning Hai is my friend. You may not have heard of him, but you may not be able to find out about him from my other friends. Because he is engaged in a confidential job, "Ning Hai" may not even be his real name
