Zhang Che's spirits immediately rose upon thinking of that possibility.
As of now, he could only control the red sword to attack within a dozen meters or so. If the red sword was any further than that from him, there was a possibility of their mysterious spiritual link being interrupted. This greatly affected the sword's effectiveness.
After a bunch of experiments, Zhang Che found out that the sword's killing potential was not inferior to the Scarlet Meteorite Huge Sword at all. The only lacking part was having no skill attack.
Since this thing was obviously not a beast card equipment, the two were evidently two different types of objects.
However, if Zhang Che's guess was right, and the mysterious energy he obtained from killing those strange creatures was the key to controlling the swords, then he might really be able to kill someone from a thousand miles away in the future!
