Since Rezen still insisted on accepting these missions in Krome Underground, the staff didn't try to dissuade him again. He only gave a bit of advice as he felt that it was a pity if Rezen dies
However, since he was this confident, what more can the staff do? All the students in Tryst Academy are more or less geniuses in the outer walls. They naturally have their own pride and if the staff insist on trying to stop Rezen, that might just incur the latter's wrath
As such, the staff handled the procedure and recorded the mission acceptance using Rezen's student token before returning it to him. The staff also gave Rezen another token while saying "Just imbue this token with a bit of your mana. It will automatically record the number of contaminated spiders that you kill. Even a wisp of mana will enable it to work for a whole day. Don't forget to activate it! Only when the token is activated will your kills be counted!"
