After being divorced, the concubine became the first lady

Saltpeter, the main ingredient in making gunpowder.

Chu Jinjin's biggest reliance should be knowledge far beyond this era, but she knows in her heart that every world has its own development rules. Just look at hot air balloons. Things that are common in later generations are almost equivalent to bugs here. .

She didn't want to have too much influence. Everything was a double-edged sword.

It is different now.

The emergence of zombies has caused panic in the world, leaving almost no resistance.

Zhan Qin was stunned for a moment: "Okay, I will go find him when we get down the mountain."

Of course he didn't know what Chu Jinjin wanted to do, but he didn't ask. This was absolute trust and he would do it immediately.

Chu Jinjin didn't hide it: "I want to make a weapon that can destroy the Northern Desert Army."

Saltpeter regulations are stricter than weapons.

Chu Jinjin asked her father to ask before. The current method of making saltpeter is rough and difficult. It takes white sediment from places like salt lakes and heats it. It is mainly used to make fireworks.

Although it has not yet been applied to weapons, the imperial court understands the explosive damage of saltpeter. It is not difficult to obtain a small amount of it in large quantities. Ordinary officials, let alone ordinary people, cannot do it.

Chu Jinjin picked up a branch and simply drew a model of a simple bomb.

In fact, according to development, it shouldn't be too long before saltpeter is used in warfare.

Zhan Qin was so shocked that he forgot about his beauty: "This, can it explode like this?"

"In my last life, this could only be regarded as the most basic weapon." Chu Jinjin understood his shock very well. The era of hot weapons versus cold weapons was almost a dimensionality reduction. There once was a huge country. With a population of hundreds of millions, they were frightened by a few foreign guns and were forced to cede territory and pay compensation.

Although it is related to the corruption of the court at that time, we can still see the horror of hot weapons.

The war came too quickly.

Chu Jinjin didn't have time to develop more weapons, so the method was very simple. Make a basic bomb and throw it down from the hot air balloon.

Not for dealing with zombies.

The only weakness of a zombie is its brain, which will not die even if it is burned to carbon.

The one to deal with is the Northern Desert Army.

The dark clouds above Zhan Qin's head seemed to be split by a thunderbolt, and the world was sunny again. He saw hope again and murmured: "So, Jinjin, your plan is to go to the Northern Desert first to buy time for us?"

Chu Jinjin stood on tiptoe and gave him a kiss: "That's right."

The morning sun seemed to be shining gold all over the ground. She had not yet put on her men's clothes, half of her strong chest was exposed, and she looked extremely handsome.

She went to the Northern Desert and got close to Mu Wei for the first time to find out what kind of relationship he had with the outsider.

Where did the zombie virus come from?

Chu Jinjin had an intuition that this world was different from the apocalypse. Since the zombie virus could come out of thin air, there should be a way to eliminate it.

For example, there are plants whose names I still don’t know.

It’s not in the apocalypse, and it’s not seen by any imperial doctor. How did it come about? If they are alive, and if they can be grown in large quantities, then zombies are nothing to fear. When the time comes that they are no longer afraid of biting, they will lose their biggest threat.

Judging from Mu Wei's reaction, this plant should be controlled by the time traveler.

Second point, buy time.

Xiao Huai has little hope. Chu Jinjin's biggest feeling for him now is that he is a bit weak and does not have the courage of an emperor.

If he has enough attitude, then Chu Jinjin will definitely go all out. She can modify bombs, hot air balloons, and various siege equipment.

It can only be said that Xiao Huai lost perhaps the biggest opportunity in his life.

Zhan Qin's face was filled with sunshine, and he said with a smile: "Jiedu will be crazy with joy, Jinjin, you may not know what this means to him."

Chu Jinjin curled her lips: "What don't you know? Doesn't he just want to take over the world? As for his true identity, he can tell it if he likes. It's okay if he doesn't tell it."

Chu Jinjin is not sure whether Jiedu will be a good emperor, but at this stage, there is no other choice, at least better than Xiao Huai.

Zhan Qin did not follow the analysis, and he did not care. As long as he could be with Chu Jinjin, anyone could be the emperor. He stared at the drawings on the ground in silence for a moment: "Come with me to see him. I'm afraid it will take a long time." Just make it clear.”

It's not as simple as Chu Jinjin thought.

Of course a certain amount of saltpeter is fine, but in a war, the more the better.

As far as he understood, the imperial court only had so much saltpeter inventory. As Yuan Tianyou, it was no problem, but it would definitely alarm Xiao Huai.

When the war breaks out, the secret of saltpeter cannot be hidden, and there is no way to explain it by then.

Chu Jinjin had already thought of this. He was Zhan Qin's father. How could he harm him? Chu Jinjin made a gesture: "What I mean is to force him to go with him."

With Chu Tianyou's guilt towards Zhan Qin, he could even risk his life, but Zhan Qin's request to come to his door was a mere saltpeter, so how could he disagree.

When the saltpeter is obtained, find an opportunity for him to come to the Chu family and go to Black Eagle Village together.

Zhan Qin: "."

Chu Jinjin took his hand and said, "Let's go and see what happens."

The capital city in the morning was still bustling and lively.

But if you look closely, you can still find the difference.

More than a hundred people who were bitten have turned into corpses. The imperial court has sealed off the nearby area and strictly prohibits anyone from entering. However, there is no airtight wall in the world, and various speculations have spread among the people.

Someone heard a hairy scream late at night.

There are also some relatives of ordinary people who want to visit, many of whom have some connections, but they have tried their best not to get any information about them, let alone see their relatives.

Without an imperial edict, no one can do it.

In this way, the unknown panic spread quietly.

What happened?

The Chu family medical clinic was full of people, some were seeking medical treatment, and more were buying medicine.

The people didn't know, but the officials knew that these medicine buyers came well prepared, and they were all buying medicine to treat wounds.

Chu Jinjin sighed softly.

If the end of the world is really coming, the most important thing to stock up on is food and other supplies that can be stored for a long time.

You should send a letter to Jie Du and ask him to make preparations in advance.

Black Eagle Village is like a small country, self-sufficient, but the more oil, salt and herbs, the better.

The Prime Minister's Mansion is very close to the Imperial Palace.

This is Chu Jinjin’s first time here.

When the servant at the door saw Zhan Qin coming down from the carriage, he immediately came to greet him respectfully.

He knows how important Zhan Qin is in the master's heart now.

Before the compliment could be uttered, Zhan Qin turned around and helped out a young woman considerately.

servant:"."

If I guessed correctly, it was definitely the evil star.

Chu Jinjin might not have imagined how much of a shock it would be when she directly grabbed the prime minister's wife and went to the palace to complain.

Is this what normal people do?

Zhan Qin didn't look at him at all: "Is Mr. Yuan in the house?"

The servant wiped his sweat, and his attitude could not be lower: "Master Qi, I have entered the palace, but my wife and the second young master are here. Look."
