Wu Xi looked at Yu Su and pleaded, "Yu Su, don't be angry."
If Yu Su left in anger, no one would be able to treat her son's illness.
If not for the two elders, Wu Xi would have chased Chen Ci out of the ward.
Yu Su smiled. "It's fine. It's quite simple to prove if there's a worm in his brain. I'll do a simple ritual and use a catalytic talisman to guide the worm to the surface of his skin. Then, you'll be able to see the shape of the worm."
She paused for a moment and said, "However, the patient will be in some pain during the casting process."
Yu Su could only lure it to the surface of his skin and could not really lure it out.
One of the great advantages of catalytic talismans was that it could allow the worm to move slowly whilst it is in a deep sleep and finally appear without alerting the person who planted the worm.
It did not hurt Hu Rui as well.
