The matter of Russia's two demigods was merely an interlude. After a night's rest at the hotel, Chen Yu was prepared to help the Russians summon the ship-girl of the Peter the Great.
All the necessary preparations for summoning the ship-girl were explained beforehand by Chen Yu to the Russians, and they had already been completed in advance. Chen Yu only needed to perform the final step of the summoning.
Even though all countries had their eyes on Chen Yu's technology, he wasn't worried about the technology leaking at all.
The Russians may have learned which preparations to complete in advance, and even obtained the magic array diagrams drawn by Chen Yu for summoning the ship-girl, but they still didn't understand how to summon a ship-girl.
