Chapter 303 Is Topology Difficult?

After registering for the English speech contest, Chen Yu checked online and learned about the competitions he could register for. Unfortunately, most of them were not suitable for him to participate in, such as entrepreneurship competitions and other design competitions. Contests, advertising contests and the like are completely incompatible with him. He did find some competitions that he could sign up for, but unfortunately, because those competitions had too little influence or for some other reason, he didn't trigger any system tasks after signing up.
