The negotiations did not occur at the EO headquarters. Instead, the wilderness in the outskirts had been chosen. According to Lu Shu's analysis, EO might be quite worried that these experts would destroy the EO headquarters if the talks did not go the way they wanted.
It did not matter who would eventually win. If the EO headquarters were flattened because of this, it would be very embarrassing for them.
Even if the large organizations destroyed their headquarters, what could they do? EO was very strong. There were no other organizations in South Africa who had two Class B experts like them. But the problem was, these two Class B experts were no match for the large organizations.
