Old Man, Where Do I Park My Car?

"Success. Want to give it a try?"

Xuan Ziwen held a wrench in his hand. He had just crawled out from beneath Mystic Ice, having finished modifying it.

Its theoretical speed on level ground could reach the flying speed of a Soul Saint. Its flight speed was about the same as a Soul Saint's as well, but if it entered Limit Realm speed while airborne, it could reach the level of a Soul Douluo.

It was a top-tier Level-7 Soul Tool. And if they did not care about the Spirit Fragments, it could even be considered a Level-8 Soul Tool.

"But what did you make this for? If you wanted one, you could have just taken a Flying Soul Tool."

Xuan Ziwen asked Jiang Bai.

Whether for long-distance or short-distance travel, this Mystic Ice was inferior to a Flying Soul Tool that could fly directly.

Flying was always faster than running, right?

"Compared to this, I want everyone to be able to use it. How does the cost of a Level-7 Flying Soul Tool compare to this?"

Jiang Bai asked.

"Mm, naturally, a Level-7 Flying Soul Tool costs more."

Xuan Ziwen said.

Compared with a Level-7 Flying Soul Tool, this car was far cheaper to make.

A Flying Soul Tool had to account for many things: airflow, jet angles, the pressure its wings could withstand, and all sorts of other factors.

That was how researchers were. The Soul Masters using aircraft up front only needed to consider whether they could fly, while researchers like them had many more things to consider.

"If we exclude the energy source and flight capability, the cost of one Level-7 Soul Tool could equal seven or eight cars."

Xuan Ziwen answered. This was only a rough estimate. If they optimized the materials and power system
