Lightning Protection: Two male protagonists! ! Two male protagonists! ! Two male protagonists! ! (Say important things three times, straight men don't come!!) + Don't follow the timeline + Cheng An is a human-shaped "explosive" + Pay attention to the party but not the party + The author's writing style is poor, it is essentially a CP article written by a female channel! Shuang Jie, Tie Zuo Cheng You Railway thought that his adopted son just went to major in command. Five years, no news. All he ever received was "the students are safe and studying normally." Until that day, an encrypted file was placed on his desk: a technical special operations officer, codenamed "Explosives", a graduate with a direct PhD in ammunition engineering and explosive technology, and the chief designer of new explosive equipment for the entire army. In the file photo, the young man with short hair, wheat-colored skin, and small tiger teeth at the corners of his mouth was looking at him quietly. He has signed and approved countless equipment applications, used the "Worker Bee" series of equipment countless times, and praised the "genius designer" countless times. Little did he know that all the explosives that helped him clear the way on the battlefield were made by his adopted son. Cheng An licked his tiger teeth, stood behind Yuan Lang, and grinned at him: "Hey, captain, long time no see."
