He couldn't possibly come here without some preparation. His greatest advantage in facing these people was that they had no idea about his background. They only saw him as an ordinary official, which was what he always portrayed. His file had been altered by his father before his arrival, concealing his background. These people thought that as long as they controlled him, they could control the overall situation, not knowing that he had already informed his father before coming here. However, it would still take some time for his father's rescue to arrive. One day, two days, or three? If he could hold on for this period, he might be able to escape the danger.
Of course, he could not reveal his identity, as that would startle the snake in the grass. Although it would make these people wary of him, it would also give them time to prepare, and the magnitude of this matter was stunning. One misstep might lead to complete failure.
