The Emperor had gone through multiple shocks in just the last few minutes.
First, Alex had somehow taken away the entirety of the Azure Dragon's treasure and body, something even he was incapable of.
Then, he had declared war against him and his empire. That was something the prophecy had said would happen, but it hadn't completely happened, so there was some solace there.
After that, Alex had brought out a ship full of thousands of people, ready to fight in the war that had just been declared. Their soldiers were surrounding the ocean, waiting for any army from the Southern Continent trying to sneak in, but to his surprise, they were already there.
Then, there was the surprise that Alex had given him with the trade. The techniques he had been presented alone had been something of a great shock, but what was more shocking was the fact that they apparently came from an individual from the higher realms who called himself the Alchemy God.
