The three national leaders originally thought they would meet Yan Fei first, to confirm the specific procedures of the surrender ceremony and the content of the surrender document. Unexpectedly, they did not meet Yan Fei at all and were directly sent to the ceremony site for signing the surrender agreement.
The surrender ceremony was held in Dream Island's largest conference center, a high-tech venue meticulously crafted by Dream Island with equipment whose sophistication far surpasses Earth's technological level. It has just been completed and hasn't been officially unveiled, yet its first public appearance became the site for the signing ceremony marking the end of World War III.
