When Wu Qiong saw Fu Hongyan going away, she became anxious at that time. She was thousands of miles away, afraid that she would be killed by robbers or wild beasts on the way.

He hurriedly shouted:

"Wait a little longer!"

Fu Hongyan frowned and turned her head. Wu Qiong held it in for a long time before saying:

"I will help you kill Yang Shuo. Can you take me back to Chang'an?"

Fu Hongyan said almost without thinking:

"I think you don't have martial arts skills. You can't help me, so you can only drag me down. If you ask Chang'an, you'd better go east earlier. You may be able to go there before winter."

Wu Qiong had already expected this situation, so he took another step forward and said:

"I know spells."

"Spell?"

"Booming the sky, but you have to prepare three things for me."

"What?"

"Saltpeter Charcoal Sulfur."

Fu Hongyan thought for a while and said:

"I don't have that much time, and I don't believe what you said."

"Then you can give me a glass of water and a piece of paper, and I'll show you the simplest spell."

After Wu Qiong finished speaking, Fu Hongyan thought about it and nodded.

There is a water cup in the room, and it is not difficult to buy paper, as long as you have money, it is enough.

Not long after, Fu Hongyan came back with the paper.

Wu Qiong did a simple physics experiment.

Fill the water cup, the paper fits seamlessly onto the water cup, and…turn the water cup over.

"How did you do it? Why is this paper..."

Fu Hongyan looked at the phenomenon in front of her incredible way. Although the water cup was turned upside down, the water did not pour out, and the paper did not fall down. It looked like paper blocking the water in the teacup.

"Haha, now I believe it. I definitely can't tell you how to do it, but this is the simplest. The thunder fire I mentioned is amazing. It's used well. Kill a Hulu eight hundred miles away."

Wu Qiong closed her eyes and started to blow, while Fu Hongyan frowned and said in confusion:

"Isn't it a thunder?"

"Uh, it's okay to call it, it doesn't matter. Go and prepare, I'll let you open your eyes."

...After an hour...

"This is the clothes, this is the sloppy head, this is the boots, you can change it."

Fu Hongyan put a bag of clothes in front of Wu Qiong, and then put another bag of things, which is what you need.

"Thank you. Please avoid it for now."

Wu Qiong hugged Fu Hongyan, but Fu Hongyan asked immediately:

"Why? This spell process cannot be shown to others?"

"Uh, no, I want to take off my clothes..."

Fu Hongyan was stunned, then turned around and walked out.

Wu Qiong was busy in the room. He first changed a set of clothes to make himself look less strange, and then mixed gunpowder and put it in a bamboo tube.

After finishing his work, Wu Qiong looked at the simple gunpowder he had just made in front of him nervously.

To be honest, although he has consulted a lot of information and watched videos, he has a very rich theoretical knowledge, but it is the first time he has really started to operate it. Wu Qiong really can't say how much this can be achieved.

In addition, there are no professional tools on hand, so I can only use original tools to weigh them, and even the leads are simply made with candle wicks.

Then put the whole thing into a small piece of bamboo tube, leaving the part where the lead is at one end.

So we made firecrackers, the first firecracker in the world made of gunpowder.

This lethality is probably not very big, but the noise is probably not small. Wu Qiong only needs to make a big noise to prove that she really knows the so-called "spells". I believe Fu Hongyan will bring her. After all, assassinating Yang Shuo is definitely not an easy thing.

As for why Fu Hongyan assassinated Yang Shuo and came to Yumen Pass, Wu Qiong guessed that Yang Shuo might have escaped, and Fu Hongyan followed him, which is a relatively high possibility.

After all, Wu Qiong thought about it. If it were Yang Shuo, he would run away as soon as possible. Don’t run away and wait to die?

Everything was ready, Wu Qiong walked out of the room with the bamboo tube. Fu Hongyan hugged her arms and leaned against the door frame and waited quietly. When she saw Wu Qiong coming out, she stood up and heard Wu Qiong say:

"We have to find a wide open place. This inn will definitely not work, it will scare people."

After Wu Qiong finished speaking, Fu Hongyan nodded and then said:

"Come with me."

Fu Hongyan took Wu Qiong all the way away from the inn. Wu Qiong changed into clothes. When he walked out, no one would give strange gazes.

He looked like an ordinary ordinary person, but his clothes were quite inconsistent with Fu Hongyan.

The two of them came to an open space. The so-called open space was just a few trees. There were no people around, but there was a market not far away, with people coming and going, which was about a hundred meters away.

"It should be big enough here. Please use the thunder you mentioned. I'll see if it's powerful and can walk with me."

After Fu Hongyan finished speaking, Wu Qiong nodded, then took the firecracker far away, then took out the prepared fire stick and lit the lead.

Without the obstruction of candle oil, Wu Qiong once again poured some gunpowder on the wick. Although the burning speed was not very fast at this time, it was not too slow.

But in Fu Hongyan's opinion, it's still a bit too slow:

"Is this the sky-bang thunder? Why did it burn..."

Before she finished speaking, Wu Qiong had already covered her ears and then heard:

【Bang--!】

With the loud noise, the ignited gunpowder exploded and Wu Qiong used gunpowder to stuff the bamboo tube slowly!

Fu Hongyan was shocked by the sudden loud noise, and even took two steps back. Wu Qiong was mentally prepared. Moreover, during the Chinese New Year when he was a child, he listened to this thing a lot all day long. Although he couldn't put it out when he grew up, this bamboo firecracker, compared with those modern big guys, such as sky thunder, loud cannons, etc., is nothing?

Wu Qiong held his hands together and laughed:

"How about it, is it okay for me to use the thunder in this primary version of Tianlei?"

Fu Hongyan looked at Wu Qiong, then looked at the bamboo tube that was blown in half. If there were no swords to cut, the human power would have been constantly making bamboo tubes. This thunder bombarded the sky was blown in half at once?

However, the crowd not far away was attracted by the loud noise, and someone vaguely heard:

"What sound?"

"I don't know."

"Is it thundering?"

"It doesn't seem like it's thunder, does it mean that the Thunder God?"

Fu Hongyan hurried forward and grabbed one of Wu Qiong's arm and said:

"Go away."

Wu Qiong also knew that it might be a bit inappropriate to be seen by ordinary people or officials, mainly because the time and place were inappropriate. Then he explained it and explained it, so he followed Fu Hongyan to leave the so-called open space.

The two walked to the street, and the pedestrians on the street were looking at the place where the firecrackers were just set off, and their faces were filled with gossip.

Have they ever heard such a loud sound? There are thunders, but thunders are not like this.

Wu Qiong walked beside Fu Hongyan and said:

"How? Look at my trick, can I help you? Actually, I honestly tell you that this thing is of great use, and it is more useful than killing Yang Shuo. It doesn't matter whether Yang Shuo dies or not. My sky-blasting thunder must be delivered to Chang'an as soon as possible. Uh, that is, if you send me to Chang'an, the emperor will definitely reward you with great reward! Do you understand?"

Wu Qiong began to tempt and said in a scrupulous manner, but Fu Hongyan just asked:

"Who are you?"

Wu Qiong smiled and bowed:

"In the lower Wu Qiong, the smart man with the number one in Tianzi."
