บท 597: Breaking Through One Hundred in Two Seconds, the Powerful Energy Stone Engine! Part 3

"The engine doesn't need to be replaced. The battery life is acceptable for now, and as long as we bring extra energy stones, we can successfully explore the terrain!"

The main components of the whole climbing car, the tire and engine were both solved, so there was no need to delay the manufacturing process further.

Immediately, they replaced the prototype version of the climbing car with new energy stone batteries. Su Mo drove while Ai Jianfeng and Lu Kuan were the passengers as they quickly headed toward the village. 

…

"Was it a success?" 

In the underground shelter, Su Wei, who was still researching the robot, raised her head in surprise as she saw the three return with joy and hurried forward to ask.

"Yep…

"The engine and tire issues have been resolved. What's left is to solve the material issue!"

Su Mo met with the robot that had a happy expression.

He was startled and became a little embarrassed.
