Hearing this, Yun Shan didn't need any further urging and gleefully took out his cell phone.
He brought up Lin Jinyun's phone number and laid it in front of Di Wu Hui.
To prevent Di Wu Hui from not being able to see the number due to blurry old vision, Yun Shan considerately pointed and said, "Here, this is the Lin Family Head's mobile number, do you recognize Arabic numerals?"
Yun Shan was genuinely worried.
The Di Wu Family was actually divided into two groups now.
One group, like the Mu family, was engaged in business and had formally integrated into the secular world.
The other group, which included people like Di Wu Hui, had divination talent and stuck to their old professions, with no shortage of interactions with the Ancient Medical field and the Ancient Martial World.
These people didn't have much contact with modern society, and some of their habits were no different from ancient people.
What if they didn't recognize Arabic numerals?
