As the sword and stone rubbed, the fire splashed.

Seeing this, Yuan Bao lost no time in catching the spark foam that fell from the black water.

As those star-like sparks fell on those black waters, there was a 'boom' and quickly burned.

Seeing this, Mo Junyi's eyes widened, and he was surprised.

And Yuanbao grinned at the corner of his mouth and smiled like a fool.

"What is this black water?"

Although I don't know what this black water is, it's just that looking at the black water that burns quickly as soon as it touches the Martian foam, and burns so vigorously, gradually, Mo Junyi also understands the role of this black water.

Seeing this, the corners of Yuanbao's mouth grinned, nodded affirmatively, and said.

"It's oil, a liquid that burns up at a little bit, and it's very powerful, and it's precious to us! I can't think of it here. If we had this oil, we could use it as a barrel for explosives. ”

Looking at the constantly burning black water, Yuanbao's eyes lit up.

Although in the past, she was just an ordinary student, every day was three points and one line, and life was very simple.

It's just that the grandfather who adopted her is not a simple person.

It is said that the grandfather who adopted her was a retired soldier and had a lot of books in his study.

Many of those books are about weapon making, explosives, gunpowder traps, and so on......

At that time, when she was idle and bored, she liked to look through the books he left behind.

Because she thinks those books are much better than those in the library outside.

I read a lot, and the contents of those books are all memorized in my head.

Now, looking at these black waters, the ingots suddenly had an idea, and they really wanted to make explosive barrels.

If she had this oil, she would be able to make the Weapons Department make iron drums full of oil according to her design, and when the time comes, these things will be the most advantageous weapons against the enemy!

The more I thought about it, the more excited I became.

Compared with the young man whose face was full of excitement and excitement, as if he had seen a treasure, his bright eyes seemed to be full of sunshine, shining brightly, so dazzling.

Although, Mo Junyi also felt that this black water might be a treasure, but for him, it was just like that.

It's just that now looking at the young man's excited appearance, the corners of Mo Junyi's mouth couldn't help but hook slightly......

……

Because of the discovery of this oil, Yuan Bao was very excited, and he just wished that he could have a Ruyi door of Doraemon, and he could return to the barracks at once.

Although, Mo Junyi subconsciously didn't want to return to the barracks so soon, and wanted the two of them to be together simply, but after seeing that the young man was excited and excited since he discovered this black water, like a little bird, Mo Junyi was helpless and had to speed up.

So, at dusk, the two of them finally returned to the barracks.

When the ingots returned to the barracks, the entire barracks was boiling.

Everyone was overjoyed, especially chasing the wind.

As soon as they saw the ingots coming back, their eyes kept falling on the ingots, ignoring the existence of Mo Junyi.

"Yuanbao, are you alright? Last night, when the enemy army attacked, I saw the enemy army sneaking up on you from a distance, and I only hated that I was too far away from you, so I could only shout for you to be careful. Finally, seeing you flee on horseback, I was relieved and worried. Plus you didn't return overnight, I also looked for you all night, I thought something happened to you, fortunately, you're fine......"
