But it's very easy to use.Our cement is environmentally friendly and non-toxic.It has passed green certification from the European Union and other countries.Can withstand high temperatures above 5000 degrees Celsius.Even if you go to Antarctica to dig a well, it won't freeze.If a nuclear bomb hits your well,It remains motionless!The Rocket Army never thought of this.The new generation of intercontinental ballistic missile silo-specific cement that has been stuck in the neck of a bear for many years.It was actually conquered by a famous township enterprise!A few days later,Zhang Tong was stunned."I bet you are really using it to dig wells. How come the Type 101 cement from our factory has become a first-class confidential and scarce strategic material?"Rocket Army: "Civilian use must be lowered!"The township cement factory was transformed into a private military enterprise by accident.
