Flying Sword or Throwing Knife?

The experiment had succeeded!

But Chu Fei did not immediately focus on the floating sheet of copper. Instead, he stared at the Wisdom Tree Seed within his consciousness space.

Yet the Wisdom Tree Seed had already become sluggish again, slowly rotating at its leisure.

Chu Fei watched for a long time without seeing the slightest change. In the end, he could only softly say, "Thank you."

Only then did Chu Fei turn his attention back to the sheet of copper before him: two centimeters wide, thirty centimeters long, and two micrometers thick.

At just two micrometers thick, the copper sheet truly was as thin as Cicada Wings—Cicada wings were only one to five micrometers thick.

A sheet of copper this thin felt as though a hard breath could blow it apart. Yet this very sheet was now extraordinarily tough.

Chu Fei picked it up and waved it around. It was as hard as a steel plate, yet exceedingly light.

However, the energy contained within the copper sheet was slowly dissipating, and it was gradually softening. Once Chu Fei injected more energy into it, it began to strengthen again.

After some thought, Chu Fei took out his broken saber. It was made from Atomic Array material.

He swung the copper sheet down. With a sound like wood being cut, the seemingly fragile copper sheet sliced into the broken saber like a steel blade, cutting two centimeters deep into its edge.

The broken saber, which should have been hard, was like wood instead. The saber was only 4.2 centimeters wide in total!

And that was without Chu Fei putting any force into it.

He pulled it out and swung with force...

With a clang, the saber was cut cleanly in two.

Chu Fei looked at the gleaming cut and felt genuinely shaken.
