As soon as Charlie said there was a way, Hamid immediately asked with excitement: “Brother, what good way do you have, hurry up and teach me!”

Charlie asked him: “I remember you said that you seemed to have purchased a batch of thermal imagers?”

“Yes!” Hamid hurriedly said: “I spent a lot of money to buy a batch of Russian-made thermal imagers, all military grade, one can be exchanged for a Mercedes-Benz car, if you had not helped me to solve the funds, I certainly can not afford these.”

Charlie said: “That’s good, you are now building civil engineering and are vigorously developing infrastructure. There should be a dedicated demolition team, correct?”

“Yes there is.” Hamid said: “I use blasting to open mountains and dig holes here. Generally, I drill holes in the rock and bury explosives, and then excavate manually after blasting.”

Charlie asked him, “Is the detonation method electronically controlled?”

“Yes.” Hamid answered affirmatively: “The electronic controls are each equipped with a detonator. After laying the wire, a twist on the switch will detonate it.”
