Craftsman: "Great, we've finally made some progress."

"I didn't expect that the research on gunpowder would make such great progress on our first visit."

"It can actually create a crater."

"Yes, I remember the last test. Although the gunpowder exploded, it didn't create a crater at all."

"It has no lethality at all."

"It's amazing to think that we made this gunpowder so lethal with just a few minor adjustments."

"Very good."

Qi Pan: "Record the data. After dinner, you can take a short rest."

"Further adjustments to the gunpowder ratio will be made in the afternoon."

"This time, we were able to successfully make the gunpowder explode, and it has a certain degree of lethality, which proves that our research direction is correct."

"As long as we make targeted adjustments, we can try to expand the explosion range of the gunpowder."

"It would be best if we could blow up this entire area and turn it into a deep pit."

Qi Pan pointed at a mountain and said, "As a final test result, I'm going to blow that mountain down."

The craftsmen looked in the direction of Qipan's finger.

Suddenly I felt the pressure doubled.

Just now I felt happy and excited because the gunpowder exploded successfully and had a certain degree of killing power.

It became heavy in an instant.

This pressure is extremely great.

It would be so easy to blow up such a huge mountain.

The ratio of gunpowder needs to be carefully considered.

If there is still one gunpowder bag that cannot be exploded, how many gunpowder bags are needed?
