5V voltage is still too weak, Zheng Fa opened his cell phone and searched online for a long time.
Finally, he found a treasure for Cultivation—a variable transformer!
After placing an order with a local merchant, Zheng Fa headed out towards the classroom.
As he entered, he noticed a slight change in the classroom—right next to the main door near the blackboard, there was a new sign that read: "XXX days until the college entrance exams!"
Tang Lingwu was standing underneath the sign, holding a stack of number plates with red numbers on a white background.
The classroom was crowded, with students clustering in small groups, chatting.
But most of the students' eyes occasionally drifted towards the numbers in Tang Lingwu's hand, as if those little squares held significant meaning.
When Zheng Fa reached his seat, his best friend Wang Chen was slumped on the desk, not even greeting him. His expression was similar to most in the classroom, slightly anxious.
