At the beginning, his wife came to him, and he became rich by selling kidney treasures.

Facing the angry Wen Yan, Ren Hao walked into the mansion as if nothing had happened, smiled and said, "Isn't this normal? How does that saying go? The magistrate is more important than the common people. If the common people die, they can be transferred from other places. But if he, the magistrate, dies, then this position will be passed on to someone else."

"This bastard, if I can go back alive, I will make my royal brother chop off the head of this dog official." Wen Yan was so angry that he pounded the door of the mansion and followed him into the mansion.

Although the population of Heyang Prefecture had long been depleted, there were still some leftover food and other supplies in the prefecture.

Ren Hao asked everyone to rest on the spot for a night to get enough rest, and then to divide into batches to mix in with the merchants early tomorrow morning, and take shortcuts to bypass the God of War Pass and attack the Wei army camp directly.

In order to make the raid successful, Ren Hao also purchased a large amount of sugar from the merchants who came to Heyang.

This era is different from the era in which Ren Hao lived before. In the world in which Ren Hao lived before, granulated sugar, which was refined from cane sugar, was not available until the Tang Dynasty.

But the reason why Ren Hao was able to have Sucrose so early in the era he traveled to was all thanks to the dedicated research of Lin Nanfang.

They didn't refine the so-called elixir of life from molasses, but they did refine granulated sugar that was sweeter and purer than sucrose.

In ancient times, sugar was made from sugarcane or malt. Malt sugar was produced in abundance in the Northern Wei Dynasty, while granulated sugar was produced in abundance in the Han Dynasty and Linnan.

The Northern Wei Dynasty was unable to grow sugarcane due to its terrain, and traveling merchants from all over the country would purchase large quantities of sugar and resell it in the Northern Wei Dynasty.

The silver earned from reselling sugar in the Northern Wei Dynasty was used to purchase salt, iron, tea, etc. and to exchange them for gold, silver, jewelry, livestock, etc. in the Western Regions. The bandits, posing as traveling merchants, would plunder weak small tribes or Hu merchant caravans, capturing strong Hu men and young and beautiful Hu women, and finally returning to Hanjing via the Qinxi King's fiefdom to sell them.

The sugar that Ren Hao bought in large quantities was not for eating, but for making homemade firecrackers.

What did the friend say?

One saltpeter, two sulfur, three charcoal, add a little sugar and make Big Ivan.

Saltpeter can be scraped directly from the broken wall, charcoal can be burned directly, and as for sulfur soil, if there is none, some dry soil can be used to fill the gap.

Ren Hao filled discarded pottery jars with the mixed materials, and then rolled the oil-soaked hemp cotton into strips and placed them in the jars.

This simple first generation of large firecrackers has been completed.

The reason why Ren Hao wanted to make big firecrackers was to successfully destroy the Wei River above the Wei army.

If they relied solely on manual labor to destroy the Wei River channel and divert the water from the Wei River to flood the Wei army besieging the Zhanshen Pass, it would take a week even if 10,000 people dug the ground day and night without eating or drinking.

Therefore, this strange strategy of launching a surprise attack on the Wei army camp, digging up the Wei River and flooding the Wei army to relieve the siege of the Zhanshen Pass was actually to use people as bait to die in order to relieve the siege of the Zhanshen Pass.

These are the words that Ren Hao did not say at that time. Anyway, it would not be their turn to die.

But it was also because of this that he miscalculated and did not expect Xu Qing to personally lead this death squad.

If they want to survive now, they must destroy the Wei River. Otherwise, facing the returning 500,000 Wei troops, their 10,000 men will be unable to escape even if the Overlord is still alive.

In order to test the power of the firecrackers, Ren Hao found a secluded corner and used a fire stick to light the hemp cotton hanging outside the altar.

As the hemp cotton burned, Ren Hao immediately ran to a distance, squatted down and covered his ears.

About ten seconds later, there was a loud bang, and a big hole was blown out in the wall made of stone and mud.

This thunder-like sound also attracted Wen Yan, Xu Qing and others.

They looked at the big crack in the wall, their eyes filled with confusion.

"Ren Hao, was it you who caused that thunder-like noise just now?" Wen Yan walked up and asked.

"I made it." Ren Hao nodded, very satisfied with the power of this big firecracker.

After all, even though there is no sulfur in it, it can still have such great power and make such a loud noise, which is really unexpected and surprising.

"Brother Ren Hao, what is this thing you made? Why does it sound like thunder?" Xu Qing asked curiously, and others also cast curious glances at him.

Ren Hao immediately held up a large homemade firecracker and introduced it to everyone, giving it a very loud name.

Thunderbolt.

"It's really a name like thunder."

"With this thing helping us, it's like the God of Thunder descending to earth." Xu Qing and Wen Yan both praised it with awe.

As for the other soldiers, although they didn't understand the principle, the problem was solved anyway.

When everyone was resting at night, Ren Hao worked overnight to make the thunderbolt.

During this night, Ren Hao created more than a hundred thunderbolts in one breath.

In order to facilitate the transportation of these thunderbolts, Ren Hao took out several carts that had not been taken away from the mansion and used them specifically to transport these thunderbolts.

In order not to attract the attention of the Wei army, Ren Hao hid the thunderbolts on the lower level of the cart, and used the upper level to place pottery jars filled with sugar, and covered it with two layers of straw mats.

Ren Hao and Xu Qingwenyan disguised themselves as merchants selling sugar, and each of them brought fifty Beijing soldiers as their entourage and retainers.

As for the remaining Beijing troops, Ren Hao asked them to drop their weapons and blend in with the merchants, and follow them through the shortcut.

After all, without weapons, this can greatly reduce suspicion.

"It's easy to fool people without weapons, but how are we going to raid the Wei army camp? We can't fight them with bare hands." Wen Yan asked doubtfully, and everyone else looked at Ren Hao.

Ren Hao had already thought of a plan and said, "There must be a lot of weapons in the Wei army camp. I will use thunderbolts to create some noise, and you can take the opportunity to grab them."

"This is the only way for now." Wen Yan nodded, and according to Ren Hao's plan, they split up and took shortcuts along the small paths between villages to head to Wei.

Because the Zhanshen Pass was besieged by 500,000 Wei troops, the villagers in the nearby villages moved out early. They thought the Han Dynasty was about to end, so they took their families and went directly to the Wei State.

When the sun was about to set, all the soldiers gathered in the woods three miles away from the Wei army camp.

The scouts' investigation showed that it was just as Ren Hao had said, with 500,000 troops besieging the Zhanshen Pass, and there were only less than a thousand garrisons stationed in the Wei army camp.

Ren Hao said to the soldiers, "I will take three people to find a way to get close to the Wei army camp. As soon as you hear the sound of thunder, rush into the Wei army camp with all your strength."

"Yes." The soldiers all obeyed the order.

Ren Hao took Wen Yan and three Beijing soldiers with him, and asked Heifeng to tow a cart to the Wei army camp.

When they were less than 300 meters away from the Wei army camp, they were stopped by two Wei soldiers guarding the entrance of the camp.
