Xia Wuqi's home is naturally incomparable to Zhao Ji's family, after all, it is a green brick and grass house, and when Zhao Zheng sneaked into the house, a warm current suddenly entered his heart. In fact, Xia Wuqi's family is not much better, but after all, it is much better than the dilapidated house that leaks wind and rain everywhere.

"Whew...... Damn, it's not good to say that this house is too well sealed, and I'm blind! ”

After Zhao Zheng sneaked into the house, he swept his hand in front of his eyes, and found that he couldn't even see a shadow, and he couldn't help but think of his experience in the ancient tomb.

"I don't know if they'll find my body......," Zhao Zheng muttered.

Zhao Zheng didn't think that he was dead in his previous life, but everything in front of him was flesh and blood so real, so that Zhao Zheng had to accept the reality.

"!"

Zhao Zheng shook his head fiercely, and after shaking the distracting thoughts in his heart out of his mind, he got busy.

Fortunately, Zhao Zheng had professional training in this area in his previous life, so although he did not know the structure of the house, it did not have much impact on his actions.

Zhao Zheng stretched out his hands, stepped on the ground, moved forward little by little, and after his hands touched the wall, he groped along the root of the wall little by little.

One-inch, two-inch, three-inch......

Zhao Zheng groped forward like a turtle, and he didn't know how long it took, and finally stopped in front of a wooden table. While one hand slowly pulls the drawer out, the other hand has already reached inside. After rummaging in the drawer for a while, a greasy feeling came from my fingertips, and I pushed my fingers to the tip of my nose, and a faint smell of paraffin wax entered my nose.

"Candles!"

I touched it in the drawer again, and a candle and two flints were taken out by Zhao Zheng.

"Da Da Da ......"

With a few flint crashes, the originally black hole-like house was instantly enveloped in a flash of orange light.

"Whew...... It's good now......"

Zhao Zheng threw the flint onto the table, and then began to look at Xia Wuqi's blue brick and grass house.

Xia Wuqi's house is not much different from Dr. Liu's house, but there are more things in the house and it seems slightly crowded.

After Zhao Zheng had a general understanding of the situation in the house, several bulging sacks next to the earthen stove caught his attention.

"Damn, hey!

The sacks were not sealed, and Zhao Zheng recognized the nitrate and sulfur in two of the bags at a glance.

After dividing the saltpeter and sulfur into two parts, Zhao Zheng blew out the candle, and then crawled out of the window with two sacks and ran home.

Zhao Zheng, who returned with a full load, looked at the two bags of battle results piled on the ground with an excited face, but within a few minutes, melancholy quietly crept up on his little face.

"Damn, I have rice, but I can't find a pot to cook it! Hiss...... You can't use a guy who eats, right? This...... How can this be refined......" Zhao Zheng suddenly felt that one head was two big.

The refining of nitrate and sulfur is simply a pediatric existence for Zhao Zheng, but he is stumped by the refining equipment. Looking at the few guys in the family who were used to eat, Zhao Zheng racked his brains and couldn't come up with a reason, and an extremely familiar sense of despair arose.

Zhao Zheng is not a person who is good at compromise, but the reality of the situation makes him have to make concessions, "Alas...... It seems that this is the only way to go......" Zhao Zheng said with a bitter smile helplessly.

After grinding the nitrate and sulfur stone into powder, Zhao Zheng immediately began to make a fire to boil water to smelt the nitrate, and as he stirred over and over again, the bottom of the pot, the fine white particles were gradually separated. Fortunately, there was a pile of good firewood at home, and it was not until dawn that half a bag of nitrate was completely separated by Zhao Zheng.

Against the backdrop of the stove fire, Zhao Zheng looked at the few catties of potassium nitrate of extremely poor purity that had been separated from the sack and grinned incessantly.

"Hey...... If you have this, then everything else is fine! Zhao Zheng wiped his little face that had been smoked into black charcoal and muttered to himself.

Potassium nitrate and sulfur have been prepared, Zhao Zheng took out the soot in the stove again, because of the firewood burned in the middle of the night, the quality of the soot is naturally much better than before. Since there was no weighing balance, Zhao Zheng had to reconcile and experiment little by little by feeling. Fortunately, the ratio of black gunpowder is simple, and after two or three tests, the most primitive home-made black powder was "developed" by Zhao Zheng.

As expected, the purity of the raw materials used to make gunpowder was too low and the manufacturing process was so poor that the quality of the gunpowder was poor, and its combustion effect was even worse. Looking at the gunpowder burning at such a low rate on the ground, Zhao Zheng frowned and shook his head repeatedly.

Obviously, the gunpowder made at this stage seems to be unable to meet Zhao Zheng's needs for shocking scenes.

"Shhh...... What can I do? You can't just throw all this gunpowder away and redo it! ”

Zhao Zheng looked at the whole sack of black powder in front of him in a daze, and after a long time, a flash of light suddenly flashed in his originally dull eyes!

Zhao Zheng racked his brains to recall things related to the explosion in his mind, and suddenly a flash of inspiration flashed in his mind, and the red episode of watching the movie "Mine Warfare" kept flashing in his mind. Zhao Zheng slapped his leg hard, and said excitedly: "Hey! Damn, how did I forget it! ”

Ignoring the pain in his thighs, Zhao Zheng stuffed the gunpowder into the flue of the kang and disappeared impatiently into the night rain. About an hour later, Zhao Zhengliu carried a large clay pot stolen from nowhere in his basket and staggered back home.

"Huhu...... I'll go! This rain is neurotic, endless ......" Zhao Zheng scolded angrily while carefully putting down the clay pot.

Since the day Zhao Zheng entered the army, landmines have become the most feared weapon. It is said that "recruits are afraid of artillery, veterans are afraid of machine guns", but in Zhao Zheng's eyes, whether it is a veteran or a recruit, there is no difference in the fear of landmines.

Zhao Zheng wiped the rainwater off the jar, poured black powder into the jar and compacted it, and finally sealed the mouth of the jar with sediment, and a simple mine was made by Zhao Zheng.

Looking at the huge and round earthen "mine" in front of him, Zhao Zheng couldn't help but smile bitterly, after all, he could never have imagined that a military commander of Group T, who gave the highest priority to equipping the country's advanced equipment, would stay up all night and struggle for a "mine" that he didn't know whether it could explode.

"Alas...... I hope you don't throw the chain to Lao Tzu when the time comes......" Zhao Zheng couldn't stop praying in his heart.

Unconsciously, the sky was already white, and Zhao Zheng was stuffy at this time cleaning up the pots and pans and earthen stoves that he had "ruined"; Outside the house, the streets and alleys were empty, and the rain that had been falling for a day or two seemed to have begun to have a declining force, and gradually lost its previous arrogance; Outside the city, in the upper reaches of the Zhu River, the soldiers and civilians of Zhao State, who had not slept all night, were still working together to fight the flood tenaciously......
