Lin Mo was dissatisfied with the three new interrogators because he still thought the higher-ups would send some real heavyweights his way.
If it were those people, he would have had a better chance of negotiating his terms.
After all, whether it was handing over secret intelligence from various countries or their top-tier technological products, it was definitely a matter of negotiation under the right conditions.
If the rank wasn't high enough, there was simply no way to negotiate effectively.
The three people at the door were not too pleased with Lin Mo either because they had thought Lin Mo was such a difficult character to deal with, but from his first reaction, he didn't seem as tough as they had anticipated.
On the contrary, he seemed very communicative.
As interrogation experts who had seen countless criminals, they could often tell a great deal just from the first glance.
