The cornerstone platform had to give an answer to Tang Zhen's request. This was one of its obligations.
No matter how powerful it was and how it controlled the operations of the entire war zone, it would still answer the questions of a level 1 cultivator seriously.
Of course, if there was a problem of paying, the cornerstone platform would be very principled and would not care if they did not pay.
However, when it came to Tang Zhen's questions, even if the value of the answer was high, the cornerstone platform would rarely charge.
Firstly, Tang Zhen's identity was extraordinary. He had a higher level and special treatment. He could enjoy free consultation services.
Secondly, he had enough merit points, but the rewards he received were limited. If the cornerstone platform was too stingy, Tang Zhen could also be more calculative.
The main reason was that the target of the charging system was low-level cultivators. It was also to encourage them to keep improving.
