Traveling through the famine, there is space for the daughter-in-law of the farm

Lu Shifu took off a shriveled gourd from his waist and gave it to his subordinates, "According to this ratio, let's make a few explosive bags and try them out."

The subordinate was surprised at what he said. He picked up the gourd and looked at it carefully, and saw some small and imperceptible words on it.

The subordinates suddenly realized that no wonder, as soon as Lu Shifu arrived at the boundary of Quanzhou City, he immediately asked everyone to go to the river to salvage gourds.

It turns out that they have an internal agent in Quanzhou City.

The subordinate carefully copied down the formula, and soon ordered someone to bring in some charcoal that was with the army, and carefully made explosive packets according to the proportions of the formula.

Lu Shifu waited for less than an hour. His subordinate put a freshly baked explosive bag under his eyes and said loudly, "General, the explosive bag has been made!"

Lu Shifu took the lit fuse and quickly threw it forward.

Thinking of the power described by the informant, I subconsciously hid back.

The soldiers followed him and hid behind him.

Ten seconds passed and there was no response.

A minute passed and still no response.

Lu Shifu frowned suddenly. Could it be that the informant was discovered and deliberately leaked false information to him to delay him from leading troops to attack the city.

Two minutes have passed, and there is still no response from the explosive pack!

Lu Shifu almost believed that he had been cheated.

The defenders of Yan State were so weak, and Zhangzhou and Jingzhou were captured so easily. If they really had such powerful weapons, they would have taken them out long ago.

With a surge of anger, Lu Shifu looked in the direction of Quanzhou City, planning to attack the city immediately.

"Bang--"

The explosive bag actually exploded.

The movement wasn't particularly loud, but it did explode.

Just as Lu Shifu was about to unite his army to attack, he was bombed back.

He took another explosive bag, lit it, and threw it out.

After waiting for almost five minutes, the explosive package exploded.

The explosion time is slow and the power is not great. It is far different from what the informant described in the letter.

The soldiers were quite happy. Throwing something small could actually blast the soil several meters high.

Although the response is a bit slow, it is already a good defensive weapon for defending the city.

When they attacked the city, they could also use catapults to launch catapults into Quanzhou City, or forcefully blow open their city gates.

Lu Shifu was covered in tendons and nearly two meters tall. He looked brave and foolhardy. In fact, how could he be an ordinary person who could cross the Chaoyuan Mountains in one fell swoop and capture Zhangzhou and Jingzhou with dangerous maneuvers?

Intuiting that there might be something wrong with the formula, he picked up the gourd, looked at it carefully, and asked his subordinates: "Have you sieved the saltpeter and sulfur?"

The subordinate Xiaoji pecked at the rice and nodded, "General, I've sifted everything carefully!"

Lu Shifu looked at the two words engraved on the gourd again, "purify".

The subordinate looked confused, "Isn't purification just about sifting the saltpeter and sulfur more carefully?"

Lu Shifu understood this just now, but the explosive packs they made were not effective, so something must have gone wrong.

There are no problems with the other steps, so only the word "purification" remains unclear.

When Lu Shifu was worried, a soldier walked up to him with a smile and said, "General, my hometown is close to the sea. I boil the seawater to extract crystal salt. We also call it purification. I don't know if that's what I mean."

Lu Shifu's eyes suddenly lit up, and he slapped the soldier's shoulders twice, "Go ahead and give it a try. If you succeed, I'll give you a credit!"

The soldier nodded and bent down to purify the saltpeter and sulfur. After a while, he finally got the saltpeter and sulfur with pure color and no impurities.

Lu Shifu was very satisfied and said that he would be credited with one merit.

The soldier successfully turned into a flower, and was ordered by Lu Shifu to make explosive packets.

The soldier followed the steps and an hour later, he produced an enhanced version of the explosive bag.

Lu Shifu ignited it with great expectation. As long as the explosive worked, he could blow open the Quanzhou city gate and the underground river gate and launch an attack before the food and grass were completely exhausted!

The explosive package drew a perfect arc in the air, and for one second, it didn't explode!

Two seconds...didn't explode...

One minute...it finally exploded...

After purification, the time for the explosive package to explode was indeed shortened, and the power and sound became extremely loud.

Although there is still a certain distance from what was described on the letter, but after comparing the two, the effect is already good.

The soldiers were very happy, and Lu Shifu was also slightly satisfied. However, as everyone knows, if you want to increase the power of explosives, the most important thing is to control the proportion of explosives.

Qiu Yanwen did not dare to alarm Zhao Yunning and the others to test the explosion, so this ratio was only written by his guess.

If Lu Shifu had seen the explosive packets made by Zhao Yunning, they would never laugh.

Liang Jun worked overtime, and within an hour, he made hundreds of explosive packets from dozens of kilograms of sulfur and saltpeter charcoal.

The subordinates looked at these explosive packs and asked with some worry: "General, we have explosive packs, but Quanzhou City must have prepared a lot of them. Is it too risky to launch an siege now?"

Lu Shifu looked in the direction of Quanzhou City and sneered, "We are the strongest warriors who are brave and good at fighting. How can we be resisted by a group of pretty boys? As long as we blow up the city gate, Quanzhou City will be ours!"

Lu Shifu was so confident that he naturally inquired and confirmed that there were only 50,000 defenders in Quanzhou City, and they also had 50,000 soldiers and horses!

As long as you dodge the initial wave of attacks, it will be easy to capture Quanzhou City.

Zhao Yunning was on the attic, controlling a stealth drone.

The thermal camera completely transmitted Lu Shifu's plan to attack the city into her five-D goggles.

Zhao Yunning came to the city wall and said to Zheng Duo and Liu Congzhen, "The latest news is that in half an hour, Lu Shifu will lead his army to the city and launch an attack. They also made a batch of explosives, which will allow the former army to attack the city.

The Chinese army flanked the entrances of various rivers in Quanzhou, and asked Li Sheng and Zhu Zhaoying to take precautions respectively."

Zheng Duo and Liu Congzhen didn't have time to think about where Zhao Yunning got the news, and quickly prepared to meet the enemy.

Zhao Yunning also picked a good position, picked up his sniper rifle, and waited for Lu Shifu to enter.

The princess is a noble person, not only is she not delicate, but she takes control of the overall situation and stands with them on the city wall to face the enemy.

Even though she hadn't done anything yet, it had greatly boosted morale.

After the common people found out, they all marveled at the princess's courage and courage. She was worthy of the blood of the True Dragon and Heavenly Lady!

It was really time to fight a real war. Shopkeeper Qian believed that they would win, but he still felt a little uneasy in his heart.

Zhang Mayi glanced at him, his eyes hot and firm, "The princess is the lucky star sent by God to save us! And with the blessing of Long Ze, Liang Jun will definitely never come back!"

Everyone has something to do during this time. Shopkeeper Qian hasn't heard Zhang Mayi say this for a long time. When he suddenly heard him say this, he thought of Zhao Yunning's past difficulties and the overwhelming blessings that could not be resolved, and he immediately felt worried.

Gone inside.

Suddenly, the sound of galloping horse hooves was heard in the distance, and the people's hearts were once again raised, and everyone was on alert.

Zhao Yunning used infrared sniper rifles to clearly see Lu Shifu, the leading leader, calmly aroused the corner of his mouth, "The horse is here!"
