After learning that trogatotoxin can delay the attack for several hours, Yang Guang and others determined that the Komatsu restaurant that Professor Sun had visited before the accident was the poisoning site. After collecting the evidence, Yang Guang proved to Director Zhang that Sugimoto Co., Ltd. was the organization behind the poisoning of Mr. Sun and deliberately stealing major scientific and technological secrets in our country.
Director Zhang asked Yang Guang to take a long line to catch big fish.After dinner at Yamashita, he secretly met Kumamoto. He told Kumamoto Sugimoto Co., Ltd. that he had been targeted by the national security department, and Kumamoto needs to cooperate with the plan to start the action.
