When the blueprint for advanced nuclear fusion technology in the parallel universe Earth-7 was projected on the sky without any warning, the world fell into a crazy "analysis competition." Materials scientist Lin Jianshen was the first to discover the potential for fatal radiation leakage in technology, and Earth-7 scientists who concealed this flaw are causing radiation cracks to appear in real space. Under the threat of "knowledge backlash", Lin Jianshen broke the technological monopoly mentality and united 97 countries around the world to establish the "Transverse Technology Ethics Alliance", using the earth's "controllable nuclear fission" safety data as a bargaining chip to seek radiation control solutions. This game related to the survival of mankind eventually gave birth to the "Cross-Dimensional Technology Sharing Convention", which placed every analytical technology under the framework of "all human security assessment". This is a war without gunpowder, where the stakes are the future of hundreds of millions of living beings, and what is won is the most profound interpretation of scientific responsibility.
