Returning to the Wu family, although Li Shan wanted to hear some information about the Wu family, the Wu family acted secretly, most of them were secret reports, and occasionally hearing one or two was just innocuous information.

Unconsciously, a month passed, and Li Shan didn't figure out what the martial arts family was busy with.

However, Li Shandao was not idle, the gunpowder had already been developed, but Li Shanke did not tell Wu Sansi directly. Rather, the process is not only dangerous, but also prone to failure. Therefore, no one can enter his work territory.

In order to match his lies, Li Shan also specially created two small-scale explosions. One is to let Wu Sansi see the power of gunpowder, and the other is to make others dare not enter his scope of work.

As for Qing'er, every day Li Shan would spare an hour to give her a lecture, and then assign a certain amount of homework. Later, Li Shan would take Qing'er to study some small experiments in addition to "work".

Qing'er is very interested in Li Shan's strange ideas, learns quickly, and has an open mind.

Later, Li Shan simply did not invent it himself, but put forward some opinions of the construction bank, let Qing'er explore it by herself, and Li Shan was responsible for revising and guiding.

For example, what they're doing right now, hot air balloons.

"How is it possible for something so big to fly?" Qing'er took the drawings given by Li Shan.

"This is just a theoretical calculation, because it has not been measured in practice, and the data may be a little inaccurate. But it's still possible, remember what I told you about air expansion and contraction, and buoyancy. Combining these two considerations, it is clear that this is not impossible. ”

"Okay, then I'll just try it, and make the small ones first." Qing'er knew that Li Shan was not chasing after the wind, so she happily accepted his suggestion. I took the drawings and prepared to make them.

"Haha, Li Shan, how is your palm thunder made?" Wu Sansi didn't know when he came behind Li Shan.

"Back to the master, it's basically finished, just wait until the fermentation of the materials is completed before you can use it." Wu Sansi had inquired about Li Shan's production method many times before, and Li Shan was overwhelmed. made up a set of production methods and told him, Wu Sansi probably heard it in a fog, and he didn't know what was going on.

"That's good, the more powerful one has to be made more quickly." Wu Sansi seemed to be in a hurry, which made Li Shan faintly feel that something big was about to happen.

"Door master, there's news from Wu Tianzong." A servant came to report with a carrier pigeon in his hand.

Li Shan has seen Wu Sansi receive a number of carrier pigeons in the past few days, so there must be a very tricky matter, otherwise with Wu Tianzong's intelligence and status, there is no need to ask Wu Sansi.

Wu Sansi took the letter scroll on the pigeon's leg and looked at it. His expression also changed, and he smiled at Li Shan: "You go and get busy, I won't bother." After saying that, he turned around and left.

Li Shan didn't dare to follow, because Wu Sansi's residence was heavily guarded, and he didn't know martial arts, so it was impossible for him to eavesdrop. But Li Shan also has a way.

Seeing Wu Sansi walking away, Li Shan also hurriedly ran in the other direction.

pigeon house,

Li Shan quietly looked at the steward in the carrier pigeon room. It is already impossible to intercept the information sent by Wu Tianzong, but if you can intercept the message that Wu San's thoughts are going to send. It's also a good choice. But how can you deceive the steward of this pigeon house?

Li Shan looked at the steward in the carrier pigeon room, and was anxious, Wu Sansi would spread the news in a while, and he didn't have much time.

Just when Li Shan was scratching his ears and cheeks, he saw Qing'er coming to the carrier pigeon room with a carrier pigeon.

"Steward Wang, this is a carrier pigeon from the northeast. You can take it. Qing'er sent the pigeon to Steward Wang.

"Hey, Howler." Steward Wang put the carrier pigeon in the cage and pasted a note with "Suzhou" written on it.

"Miss Qing'er, I have something to do temporarily, please take care of this place for me first. I'll be back in a moment. Steward Wang held his hand on his stomach and seemed to have a stomachache.

"Hey, Steward Wang, are you okay? Why don't you go see the doctor, I'll take care of you here. "Qing'er is still very enthusiastic.

"Hey, thank you Miss Qing'er then." The king's steward was overjoyed, and hurriedly ran out.

Li Shan was overjoyed when he saw this, the others Li Shan was really unfamiliar, and he didn't move. But Qing'er is different, this is a pillow when she is sleepy.

Originally, the pigeon room in Li Shan's laboratory was not very far, and Li Shan came to the pigeon room as if he was wandering around.

"Hey, Qing'er, why are you here?" Li Shan's expression of surprise was actually complete because he knew that Qing'er was here.

"Master, why are you here? I'm helping Steward Wang take care of the pigeon house. ”

"Didn't I tell you to hurry up and get the materials ready for the hot air balloon? I see you want to be lazy again, how can this work? Li Shan deliberately said with a straight face.

"What, it was the master of the door who sent the carrier pigeon to me and asked me to send it, and I was going to go back after sending the carrier pigeon, but the king steward suddenly said that he was in a hurry, so I will help him take a look here." When Li Shan trained her as a master, Qing'er was very weak and would not solve the problem by force, but only fought on the basis of reason.

"What's so nice about this pigeon house? You hurry up and get the materials for the hot air balloon ready, I'm here to watch Steward Wang, hurry up. Li Shan said very strongly.

"Ah, that's okay, but you have to watch it, and you must wait for the king's steward to come back." Qing'er was still a little uneasy, but she couldn't disobey Li Shan's words.

"Okay, can your master do this well? Hurry up, I'll have to punish you if you don't prepare well in the afternoon. Li Shan looks like a strict teacher on the surface, but in fact, he is a thief with a weak heart, and he just hopes to take Qing'er away quickly.

watched Qing'er take two steps and turn around to leave the pigeon room.

Li Shan hurriedly took out the cage with the note "Suzhou" written on it before, and found a cage with a note on it "Northeast" to swap the carrier pigeons inside.

"Miss Qing'er." As soon as Li Shan finished this matter, he listened to the voice of the king steward outside the door, "Master Li, why are you here?" What about Miss Qing'er? ”

Steward Wang was not too surprised to see Li Shan.

"Ah, Qing'er was called over by the door master, and it happened that I slipped here without anything, so Qing'er asked me to watch here for a while, saying that I must wait until the king steward returns." Li Shan said with a smile.

"That's really Master Lao Li." Steward Wang still has to be respectful of people who wear samurai uniforms.

"Steward Wang, the master of the door has a letter for you to send out, and it is to the northeast." While he was talking, a servant took the letter and went into the pigeon room.

"Okay, I'll send it." The king's steward, while agreeing, was going to get the carrier pigeon.

Li Shan casually took a cage with a northeast strip and handed it to the Wang steward, and the Wang steward thanked the cage when the cage arrived, and took out the carrier pigeon, tied the letter pipe to the pigeon's leg and prepared to fly.

"Then I'll take my leave." Li Shan: This is ready to retire.

"I still have something to do, so I won't send it." Wang was in charge of affairs, and he was busy releasing carrier pigeons, and he didn't care about Li Shan. went out one step ahead of Li Shan.

Li Shan saw that Steward Wang was not paying attention, and quickly took out the carrier pigeon in the cage of "Suzhou", kicked it into his arms and left.

In addition to the pigeon room, Li Shan went straight to the backyard. Because this is the place where the carrier pigeon landed, Li Shan knew that what Steward Wang was holding was not actually a carrier pigeon that was sending a message to the northeast, but a carrier pigeon that flew back from the northeast, so he had to intercept this carrier pigeon as soon as possible.

Sure enough, as soon as Li Shan arrived in the backyard, he watched a carrier pigeon fly twice in the air and then landed, pecking at the grass in the backyard.

Li Shan hurriedly went over to catch the carrier pigeon, liking that there was no one around, Li Shan cat hid in the woods with his waist, and looked carefully to make sure that there was no one, so he calmed down, took off the letter tube on the pigeon's leg, and released the carrier pigeon.

Open the letter tube and take a look. The above is concise: wait for the opportunity to intercept and kill the Silla envoy.

Li Shan was shocked in his heart, the martial arts family really has a big conspiracy!

"Hey, why is that Suzhou pigeon missing?" The steward looked at the cage empty, and the cage door was also open, and the blind was that the cage door was not closed properly, so that the pigeon escaped.

As he spoke, there was a sound of wings, and the pigeon flew back. Steward Wang smiled and put the pigeon back in the cage, the pigeon is the most recognizable bird, so Steward Wang did not worry that the pigeon would run away. (To be continued.) )
