On this day, it was the second to last day of Tang Susu's mission. As usual, she came to the gate to clock in.
This was also a loophole that she had discovered earlier. While it was said that she would need to guard the gate for 20 days, it didn't mention how long she needed to guard the gate every day. As a matter of course, Tang Susu chose to slack off. She would just walk around the gate once a day and call it a day.
Most of the time, she would hunt the T2 zombies and extract their Crystal Cores.
She found that the four Crystal Cores that she had put into the Energy Reservoir had begun to change visibly.
The gray-white Crystal Core was the lowest grade and had the most obvious change. The impurities in it were already removed, and it became a pure-white Crystal Core.
