In the dead of night, a shadow suddenly flickered within Chen Yang's base, and then with a flick of the wrist, a letter shot out, embedding itself into the iron door.
The commotion immediately alerted the guards inside the base, who hurriedly came to investigate, but they could only see that one letter. When they turned and looked around, the vast night was empty of any people.
On the envelope, it was written:
To President Chen.
—— Left by Xiao Yaozi.
The nine words, bloodstained, were written with fresh blood, exuding a strange and terrifying aura.
The guard widened his eyes, feeling horrified, and quickly sent out a signal. The entire base instantly buzzed with activity; countless experts poured out, but they couldn't find any traces at all. It seemed the person who sent the letter had escaped.
Helpless, they could only take the letter off the iron door and deliver it to Chen Yang.
