At this moment, seeing that oil could be burned, Yan Xiao immediately thought that this oil could be used as a new fuel.

However, as soon as she thought so, Yan Bei shook her head and denied: "This kind of oil can be used as fuel, but with our current level of technology, it cannot be widely used in life." ”

So, Xiao Nizi, it is impossible for your ideas to come true in the moment.

The development and utilization of oil is a very huge project. With the current level of social science and technology, let's wait another one or two hundred years.

"But ......" Just when Yan Xiao felt great regret, she changed her words and said: "It can be used in military affairs, but it is still possible at present." ”

Now that the heroine has explosives on her side and oil on her side, it depends on who moves faster is the winner in this war.

"How? The daughter is dull, and she hopes that her mother will mention it more. Yan Xiao asked excitedly.

"No hurry!" Yan Bei raised his hand and raised his eyebrows at Caisang and the others, signaling that they could pour water.

Four buckets of water were ordered at any time, and as soon as they were instructed, the envoys immediately lifted the buckets and poured them on the burning fire.

At first, they thought that if the water was poured on it, the fire should be extinguished.

Unexpectedly, the fire did go out for a moment, but before they could turn around, it actually burned.

The envoys were stunned, for this was the first time they had seen a fire that could not be extinguished with water.

"This, this...... How can this be?" The envoy exclaimed.

I don't know if I remembered some demons and monsters, and my face turned pale one by one.

This can't be some kind of monster tainted with evil spirits!

Thinking so in their hearts, they could see that Her Majesty the Empress was still standing on the flower bed and looking at it calmly, and several female envoys did not dare to say this.

However, Cai Sang was more calm, in the end, it was the empress's personal female officer, seeing that the four people were stunned, they hurriedly shouted: "Fool who has no knowledge, don't retreat quickly!" ”

“...... Yes, yes, yes! The four of them were taken aback, did not dare to stay any longer, and retreated tremblingly.

As soon as they left, Yan Xiao immediately wanted to ask the reason, but before she could speak, a sharp "ghost scream" took the lead and grabbed ahead of her.

"Ahh Your Majesty! ”

"What's wrong with you, Your Majesty? You idiots, don't hurry up and save people! ”

"Water, water, water, get water! Come on, save the driver! ”

As soon as General Ling entered the courtyard, he saw Yan Bei standing in the midst of the fire, and he was so frightened that he was called a six gods without a master, and he opened his mouth to shout for help while rushing up.

But, shouting and shouting, she suddenly realized that something was wrong.

Why is Her Royal Highness here and not showing a trace of panic?

Also, there are female officers and guards around, why don't you come forward to help?

Among them...... Could it be that the princess wants to force the palace?!

Old General Ling paused, inexplicably feeling that he had the truth.

However, why is His Majesty still smiling at her, surrounded by fire, shouldn't she shout for help?

"Old General Ling?"

"Old General Ling!"

Cai Sang shouted twice in succession, and seeing that she still didn't answer, she deliberately accentuated her voice and shouted again.

At last, the old lady turned to look at her.

"The old general misunderstood, Your Majesty is fine, the big guy is doing the test."

Hearing Caisang's explanation, and seeing everyone's appearance of covering their mouths and smiling, the old general Ling, who reacted later, turned red and asked:

"Testing?"

Isn't it forced palace?

"Test." Cai Sang nodded heavily and replied in the affirmative.

Old General Ling felt that today's embarrassment should make Her Royal Highness the Empress laugh for a year......

Yan Bei jumped down from the flower bed, directly picked up the empty buckets on the ground, and covered them upside down on the fire, and without oxygen, the burning fire gradually extinguished.

"Old General Ling, I found something good, and I was about to ask you to come and see it." Yan Bei said with a smile.

Old General Ling was still a little embarrassed, but seeing that the black liquid was very magical, he made a gesture of asking for advice, and said with a wry smile:

"Please ask Your Majesty for advice!"

"It's easy to say, there are a lot of people outside, let's go inside and talk about it." Yan Bei glanced at Caisang, who immediately nodded and stepped forward to lead everyone into the house.

The remaining oil in the yard, Yan Bei specially called Shi Wu and asked him to take care of it temporarily.

Shi Wu only felt inexplicable, after all, this kind of big secret would not be accessible to people like him at all.

But the emperor's order cannot be violated, since His Majesty has ordered, then he can only honestly take care of the remaining oil.

Before entering the house, Yan Xiao took a special look at him and saw that he was competent, so he was relieved to enter the house.

In the past, she would never have had so much to do, but this time the oil was too important, and she had to pay more attention.

However, is this really the case?

The answer Yan Xiao himself didn't know, and he didn't want to know.

Regarding the use of oil, Yan Bei can casually come up with a hundred schemes, this kind of thing is unknown to Yan Xiao and the others, but she can't understand it anymore.

With her magical head, Old General Ling didn't have to worry about anything at all, just obeyed the arrangement.

Yan Xiao is the same, she doesn't understand this thing, but as long as it is something ordered by someone who understands, she just has to do it.

Of course, this is only temporary, and soon Yan Bei will write a simple manual for Yan Xiao to study carefully.

After all, she can't stay in this world for a lifetime, and it is better to teach people to fish than to teach them to fish, and she still understands this truth.

By the time everything was arranged, it was already evening.

Yan Bei had dinner alone, and began to write a manual for using the oil in his head.

The candlelight in the room was bright, and it was written, and I didn't know if I was sleepy, Yan Bei suddenly felt that the things in front of him were a little trance.

"Grandma, grandma......"

Ay?

How did she hear someone screaming?

What's it called?

"Grandma!"

Well? Grandmother?

A thought suddenly flashed into his mind, Yan Bei's hand holding the pen suddenly froze, and a drop of ink fell down the tip of the pen on the white rice paper, exploding a black flower.

"Grandma! Dango is hungry! ”

Hiss~

"Xiao Duo, did I forget something very important? For example, leaving a child in the space and forgetting to take it out ......"

Xiao Duo looked angrily: You know that you still have to ask me!

"Hurry up and release the little ball!" Xiao Duo urged.

Yan Bei glanced at Yin Chou on the beam of the room, and then glanced into the bracelet space, the pink and tender dumplings were lying on the blue grass, two small black eyes looked at the sky blankly, and the two tentacles pulled the empty storage bag around the neck, and there was a can in it.

"Grandma...... Tuanzi is so hungry, grandma, are you done with your business? If you're done, you'll have to come to the dumplings early. The sensible and pitiful little whisper of the danzi.
