Zhao Yongjun had prepared this for Xia ruofei before he left the country the last time. It was for emergency contact.
The SIM card was anonymous, and even the phone was custom - made. Zhao Yongjun's father, Zhao Cheng, was a senior leader in the military. The military had a large number of orders for custom - made secret phones every year, so it was not difficult for him to get one or two custom - made phones.
After the call was made, Zhao Yongjun picked up after a few rings.
There was a hint of worry in his voice.""Brother, did you encounter any trouble?"
This phone was prepared for emergency contact. If Xia ruofei had returned to China, he would not have used this number to contact him. Now that he was using this number, he was most likely still abroad and might have met with some trouble, which was why he was a little anxious.
