The morning sun shone shyly on the earth with a lazy atmosphere.

Early in the morning, Xue Tiezhu shouted out the battalion recruits to hurry up and train them.

There are only two days left before the three-day period, and Xue Tiezhu's heart is like a fire.

Looking at the sleepy-eyed recruits, Xue Tiezhu was angry, and pointed to the military tent where Lin Bai was lit all night and shouted-

"See, people who are more handsome than you work harder than you, so why don't you train hard?"

Suddenly, the recruits responded loudly as if they had been beaten with chicken blood,

"The county order is mighty, the county order is mighty!"

After Lin Bai divided the troops and divided the squad, the training effect of the recruits was improved again, and it was more targeted than before.

In addition, the three-day period was imminent, and everyone breathed a sigh of relief in their hearts, after all, this was the first time they had been issued a war letter since they entered the camp, and it was a matter of honor and dignity for all, as well as the comfort of the people of Qingshan.

So they don't dare to lose, and they don't want to lose.

A breath of murderous blood permeated the barracks, a disappointed reprimand, an unwilling roar again and again, the trembling body was still holding on, and the figure who fell to the ground was still desperately moving forward......

The heart is surging, infinite passion, waving a thousand waves in the wind, and the young man is undefeated and enthusiastic!

It's just that Lin Bai was worried that if they knew that the so-called war book was just a scam, would they all chase themselves seven or eight streets with kitchen knives?

In the military tent, Lin Baiqiang held on to a pair of 'I want to cultivate immortals, boundless power' eyes that were about to close, and stared at the pile of black powder and yellow powder powder on the table.

Next to the powder, there are equations written in black and white that are very foreign to this world.

What KNO, S, C.

It just looks a little weird.

After all, it was the first time for Lin Bai to write equations with a brush.

Lin Bai carefully poured the powder into the jar, then closed the lid and plugged the gap, leaving only the gap of a fuse.

Ignition.

Zizizi......

Under Lin Bai's gaze, the self-made fuse flashed brightly and burned towards the jar like an electric snake.

However, with a snort, only a little black smoke came out of the jar.

Lin Bai: "......"

Ahhh

Lin Bai frantically opened the lid and found that the gunpowder inside, which had not yet been successfully prepared, had not burned completely at all.

The lid fell to the ground, and Lin Bai sat down on the chair with his buttocks, his eyes blank, and he began to doubt his life.

Chemistry, why is it so hard......

Lin Bai died on the trim.

One night passed, and several experiments ended in failure due to the poor proportion.

At the beginning, Lin Bai, who was just holding the mentality of trying, made it clear in the end that he would never give up until he reached his goal!

Looking at the paper again, Lin Bai patiently analyzed it again.

This carbon is not wrong, and sulfur is also fine, but potassium nitrate is a little uncertain.

Could it be that there are three oxygen anionions in the nitrate?

Try it.

Well, in this case, it's two parts saltpeter, three parts carbon and one part sulfur.

Mix well, wrap on paper and place in jar.

Ignite.

Lin Bai's heart slowly moved to the inside of the jar as the fuse burned, and he followed his head closely.

Then, boom, the lid was directly rushed into the air, and Lin Bai's face was also blown to the ground like black charcoal.

However, Lin Bai laughed directly.

Hahahaha!

The emperor lives up to his wishes, I, Lin Bai, finally succeeded!

I developed gunpowder in another world, and I, Lin Bai, am simply a genius!

The strange noise was drowned out by the neat shouting outside.

This kind of joy that no one could share made Lin Bai feel a little pale.

Or...... Making a splash?

Increase the amount a bit, half a jar should be enough.

Lin Bai found two more stones to compact the gunpowder, and then closed the lid and lit the fuse.

But when Lin Bai thought about it, he felt a little dangerous again.

So the jar was placed under the chair, and Lin Bai sat on the chair with confidence.

On the school training ground, one by one the sergeants were in full swing for physical training.

I heard a loud bang—

Lin Baisheng had nothing to love and flew into the sky in despair.

"Oops, my waist flashed. ”

Many of the sergeants who were training were startled by the loud noise.

But when they came back to their senses and looked in the direction of the explosion......

"Look, the county order is in heaven!"

"Really, why did the county order run into the sky?"

"Could it be that someone threw it up?"

"Nonsense, didn't you see that our county order has been practicing all night? This is obviously a great achievement of the county order, and it can already take off on the ground!"

Xue Tiezhu scolded solemnly.

When everyone heard this, their eyes instantly lit up with envy.

"Wow! The county order martial arts are unparalleled in the world!"

"The county order is unique in the world, reaching the peak!"

"The county order is mighty, and the county order is domineering!"

Lin Bai fell in front of everyone, looking a little embarrassed.

"County ......"

The cheers stopped abruptly, and everyone looked at Lin Bai, who was lying on the ground and was constantly covering his face, and the atmosphere was slightly embarrassing......

"What are you doing in a daze? Why don't you hurry up and send the county order to the hospital?!"

......

Fortunately, my Lin Bai cultivation is profound, and my blood is vigorous, and the little copycat bomb can only up to the sky.

In the martial arts stage, due to the increase in qi and blood, the physical fitness will also improve rapidly, and the toughness of the skin is several times higher than that of ordinary people in previous lives!

Therefore, in this human trial, the bomb did not bring much substantial harm to Lin Bai.

It's to be embarrassed in front of the recruits...... My Lin Bai's little heart can't stand it a little.

After learning from the pain, Lin Bai immediately discovered the problem of insufficient lethality of the bomb, and the root cause of this problem was because the strength of the shell material was not enough.

If you replace the shell with an iron shell, and add some iron needles and iron pieces to the gunpowder, you will feel that the damage will be off the charts!

Not to mention, I, Lin Bai, have always been a resolute man.

In the military tent, Lin Bai broke the iron with his bare hands and directly pinched a piece of iron into a round ball.

After the gunpowder was loaded, Lin Bai walked out of the military tent with a strange big iron ball and walked majestically to the backfield.

Along the way, many curious soldiers followed Lin Bai, and even Xue Tiezhu, a training madman, also followed.

In the backfield, Lin Bai asked someone to dig a pit that could hold the iron ball, and then buried the bomb in it with his own hands, and ordered everyone to retreat.

Everyone couldn't help but wonder in their hearts?

So what is an iron ball?

The county order buried it in the soil and told us to retreat?

What's wrong? Is the iron ball going to be fine?

But seeing that Lin Bai found a torch, he lit the fuse with trembling hands, and then ran away with a bang.

Everyone was puzzled, only to see the fuse getting closer and closer to the fireball.

Huh, what's that? It's a novelty.

Someone was curious and wanted to go up and test it, but in an instant, there was a loud bang-

Boom! Dusty, dark sky!

Everyone felt that a large flame suddenly appeared in front of them, and when the fire dissipated, the dust settled.

On the backcourt, the pit that was originally only the size of a fist has become a huge pit several feet wide!

Hiss......

Everyone couldn't help but gasp.

Silence frightens everyone.

What the hell is this?

It seems to be just an iron ball, how can it burst out with such power?

Unless, this iron ball is from the hands of the secret weapon master of the Tangmen in Shuzhou.

Could it be ...... The county commander locked himself in a military tent and studied hidden weapons all night?

"It turns out that the county order is studying hidden weapons!"

But such power......

"Is this the legendary world's number one secret weapon?"

Suddenly, there was a tsunami of cries -

"The county order is mighty!"

"The county order is domineering!"

Lin Bai lightly slapped his hand twice and stroked the hairstyle that had been messed up because he was running too fast.

After the matter, the clothes are gone, and the merit and fame are deeply hidden.

I, Lin Bai, am so bullish and low-key.
