Why did France sign the Sean Bruen Treaty with Prussia?

While Napoleon was at war with Russia and Austria, Prussia, which wavered between advantages and disadvantages, was temporarily stabilized by Napoleon, but under the instigation of Britain, Friedrich William III, a general worker, wanted to take advantage of the opportunity of two tigers to pose as an arbitrator and prepare to act as a mediator between France and Russia and Austria. If France does not accept Prussia's mediation, Prussia will join the war on the side of the anti-French alliance. When Special Envoy Wang Pu went to the French army station with this final disc-shaped mediation document for France, he got the news that the French army won a total victory, the Austrian army compromised and the Russian army retreated halfway. Special envoy Haugwick flexibly changed the last course to congratulate the victory. Napoleon knew all about it. But he took advantage of the situation and suggested signing a treaty with Prussia called alliance with France. In fact, he was a slave of France. Because the negotiation place was in Austrian Shawn Bruen Palace where Napoleon lived, the history of the treaty was called Shawn Bruen Treaty. In this way, an envoy who threatened Napoleon brought Prussia a very unfavorable Franco-Prussian Covenant.
