Threat

The four spears flew around Alex, each independently controlled by him. 

'That's a little bad,' he thought. Unlike the octopus skill from the Yao family where you controlled 4 different limbs all at once while remaining in a simple spherical barrier, this technique had no defensive aspect to it at all.

All you did was control the four spears while also focusing on defense at the same time.

"Whatever, let's try it out."

He sent the spears flying in four different directions, attacking four different people at once.

The four of them fought the spear with the aid of their friends and quickly destroyed the four spears.

Alex made four more and sent them to attack. He was judging the strength, durability, and other various properties of the spears he was making.

It was a Heaven Grade skill, so it wasn't weak at all. However, having to control all four of them made it a little worse than it really was.
