Ji Changming nodded and said, "The situation is very bad. The asteroid surface contains various rich metal components, of which heavy metals account for about one third. The density of the asteroid itself is very high, even the probing spacecraft was almost destroyed by its gravity. Fortunately, the technology of the United States is good enough to complete this detection mission. According to our preliminary calculations, at least the explosive power of seven thousand nuclear bombs is required to deviate the asteroid's orbit from the Earth's direction. Seven thousand! This number means that you must directly participate in the final action. Intercontinental missiles will serve as the first wave of attack, and you will be the second."
