Tang Zhen's control of his strength could be described as extremely wonderful.
The sharp scalpel in his hand flashed nimbly, and in an instant, the head of the strong man from the ice Bear Alliance was split open.
He took out the purple electric short sword and carefully carved on the pale skull. He appeared to be very serious.
It did not take long for a strange formation to appear on the skull of the brawny man, covering the entire surface of the skull.
After putting down the purple lightning short sword, Tang Zhen took out a soft purple metal and pulled it into a thin thread.
This was a special metal from the world of loucheng. It was one of the main materials used to forge mo weapons. It had extremely good conductivity and was many times better than silver!
After inlaying this kind of fine thread in accordance with the carved pattern, Tang Zhen carefully made a small hole in the center of the array.
