Fengtingyi is located in a mountain basin, a small river flows half a mile southeast of the post station, passes through a five-mile-long canyon, and flows southwest into the Fujiang River.

The main body of the post house is a composite garden building with a brick structure, and different courtyards are enclosed with high walls, which is more fireproof, and there is indeed no fire this time.

The thieves set fire to the buildings on the periphery of the post house.

Datang Chengping 100 years, commerce and trade gradually become developed, the demand for business travel accommodation in the past has increased greatly, in order to generate income, the successive post has built more than 10 thatched houses around the high wall, for fire prevention, each thatched house is an independent building, about three zhang apart from each other, if which thatched house is on fire, just take a bamboo pole to stand on the roof of other houses, and set aside the sparks floating in the air, which can play a role in preventing the spread of fire.

This time the thieves burned down six houses, after the fire started, it was like daylight in the distance and near a hundred zhang, the caravan guards were well-trained, and the cordon was stretched very open, and the thieves retreated into the darkness to lurk, creating conditions for the post house to fight the fire, so until now, no new thatched houses have caught fire.

If the thieves were really numerous and well-equipped, they would never dare to engage the caravan guards head-on in the light, which was another reason why Yang Yun suspected that Zhang Lin's exaggeration would shake the hearts of his own army.

The thieves took the way of tying their pockets, they took advantage of the night to touch down the mountain, blocked the mouth of the canyon at the first time, and then traced the river upstream, and launched a fire attack on the post station from the southwest, but after igniting the thatched houses on the periphery, as the caravan escorted out, they retreated to a nearby hill, and peeped in the direction of the post house in the dark.

Yang Yun returned to the grass hut, which was not affected by the fire, and took out a small suitcase full of gunpowder from the suitcase.

The inner edge of the small suitcase is padded with a layer of oilcloth paper, and the surface is moisture-proof and sealed to isolate open flames and high temperatures.

The reason why Yang Yun will bring dangerous goods on the road is mainly to deal with the troubles that may be encountered when rushing, such as when encountering continuous rainy weather, sprinkle a little when it is difficult to ignite, even wet hay is easy to ignite, in addition, it can also come in handy when resisting the invasion of jackals and other fierce beasts and small bandits.

Of course, he could always have more gunpowder at his disposal if needed.

When he was in the workshop, in order to conceal the formula and adjust the proportions, Yang Yun threw many polished raw materials into a relatively dry cave in Longquan Mountain. Now that Yarou's spiritual power has increased rapidly, if you really need it, you should be able to open the door of time and space, take those raw materials, mix them according to a certain ratio, and put them into use.

But doing this will definitely hurt Yarou's vitality, after all, the distance between the two places is too far, so if it is not necessary, Yang Yun will not try.

Yang Yun took the suitcase full of gunpowder to Lei Jiao and the others, and after opening it, the group of people stared at each other, unable to determine the authenticity, because this thing has been used for military use since it came out, and the people of the caravan have never seen it.

"This is the fire charm? Who believes? ”

Zhang Lin asked aggressively.

"Don't be impatient!"

Yang Yun raised his hand and waved, then took out some gunpowder and sprinkled it on the table, then picked up the fire fold and brought it to the edge of the table.

"Good, it's terrible."

Yi Cheng was dumbfounded, stunned for a while before remembering something, and hurriedly stepped forward to take a closer look, and found that the table was burned black, and the surface had been carbonized.

Reggio was shocked at first, but said in surprise: "This is really a good thing to save your life...... Brother Yang, I don't know how to use the fire charm? ”

Zhang Lin saw that Lei Jiao was going to follow Yang Yun's advice and fight with the thieves, so he hurriedly persuaded: "Boss Lei, the origin of this thing is unknown, how can you rashly use it to fight the thieves?" What if it doesn't work in real combat? ”

Yang Yun smiled faintly: "Master Zhang, you are really too worried, the power of this thing is far beyond your imagination, as long as it is placed in a closed clay pot, it can explode violently after ignition, and there is no living mouth within three or five zhang." Or throw it into the firewood and grass, and wait for the thieves to come and light the fire, it will quickly deflagrate, and it will be like a fire hell within ten zhang, and the thieves will be burned to the point that there are no bones left. ”

Yang Yun desperately exaggerated the power of gunpowder, and when he heard the eyebrows of the group of people around him, he felt that his safety was guaranteed this time. Zhang Lin showed an anxious look on his face, his smile was extremely reluctant, and his eyes were full of resentment when he looked at Yang Yun.

"Hurry up."

Lei Jiao immediately made a decision and said, "We can't sit still, wait for dawn to find an opportunity to break through, and rely on the fire charm provided by Brother Yang to retreat from the enemy." ”

……

……

The group prepared for more than half an hour, made five clay pot bombs, and made eight medicine bags.

The thieves were slow to attack.

In Yang Yun's opinion, the defensive pressure is not great, and the number of thieves is definitely not as many as Zhang Lin said, if the thieves know that there is a fire charm in the defense circle of the post station, a powerful "magic weapon" that has proven its power on the battlefield of Iasi, he will definitely not attack rashly.

By daybreak, the brothers in the caravan were a little tired, but they were still in good spirits to guard against any possible attack around them.

"Master Lei, have the people who broke through the siege sent out?"

Yicheng couldn't bear the huge psychological pressure, and ran over nervously to ask.

Lei Jiao said: "I sent out two horses before, but there is no news for the time being...... Why didn't the post station send fast horses to ask for help? ”

Yi Cheng sighed: "There is a shortage of war horses in Shudi, and we use mules, donkeys and ox carts to contact all parties on weekdays to buy daily necessities. Even if there are four war horses to deliver urgent news from the imperial court, there are no good riders, and it is very easy to have accidents in this dark night. ”

Datang Post Station is responsible for raising horses, and when the news is transmitted, especially when the eight hundred miles are in an emergency, the person who carries the war report usually changes horses and does not change people, and the post station itself is only responsible for providing horses and accommodation, and is not responsible for providing riders. In addition, the people in the post station have their own official status, and if they want the people in the caravan to come out to take care of the matter, there is no need to risk angering the thieves to go to the nearby state to ask for help.

At this moment, Yang Yun came over and said, "Master Lei, it is about to dawn, you should bring a group of people to break through and take a look...... There has been no movement in the surrounding valleys, and the situation is very strange. ”

"Okay."

Lei Jiao is determined to fight the thief to the end, and his confidence is much more than before.

Lei Jiao took Yang Yun to the front cordon, ordered more than a dozen executioners, held big knives, spears and halberds, and carefully walked along the official road next to the small river all the way to Suizhou.

After walking more than a mile, I could already see the entrance to the canyon, but there was no trace of the thieves.

"Withdrawn?"

Ruan Yue, who came out together, asked in surprise.

Yang Yun shook his head: "It's possible that he hid in the nearby mountains and didn't show his face...... It's best not to break through rashly before dawn, if the people sent out can contact the Suizhou officials and soldiers, I believe that this gang of thieves will flee when they hear the news. ”

Reggio approving: "This is an old saying, and it should be." Brother Yang, seeing that you are not very old, why are you so familiar with such things? Could it be ...... Have you ever been on the battlefield? ”

Yang Yun smiled and did not answer, and the group turned back to the post station.

At this time, the people sent out to inquire about the news came back one after another, but none of them found the thief.

"Boss, it seems that the thieves have indeed evacuated, or let's hurry up and take the goods on the road!" Liu said through the road.

Lei Jiao shook his head: "I still listen to Brother Yang about this matter, and I will make plans after dawn...... Let's stabilize our position first, as long as we don't mess with ourselves, we can rely on the fire charm to defeat the enemy. ”

From beginning to end, Zhang Lin didn't speak, looking preoccupied, others didn't pay attention to his reaction, but Yang Yun kept secretly observing.

After dawn, the fast horse that had been sent out to ask for help came back with the latest news...... Suizhou Zhichong Prefecture has sent two hundred-man teams to rush to the aid of Fengtingyi, and the thieves fled when they heard the wind and retreated to the Langzhou line of Shannan West Road.

The people of the caravan and the inn were worried for a night, and when they heard that the thieves had retreated, they were all excited.

Ruan Yue said: "The thieves have withdrawn, we will work hard today, and we can get to Guozhou safely, and the next road will be much easier." The thieves were menacing, and they refused to give up if they didn't eat us, but they retreated in disgrace, and we didn't spend any money...... It's incredible. ”

Lei Jiao looked at Yang Yun and said, "Thanks to Brother Yang, if he hadn't taken out the fire charm at the critical moment, how could he deter the thieves?" Fortunately, we didn't give in at the beginning, otherwise we wouldn't have been able to explain to the main family when we went back. ”

Zhang Lin looked disdainful, and said flatly: "The thief didn't know that we had a fire charm, how could it be the credit of this kid?" It may be that the thief has other plans. ”

"Hurry up and arrange for people to go out to investigate, explore the road well, make sure that there are no thieves ambushing within ten miles, and then we will go on the road." Liu Tong, as the guard and steward of the caravan, hurriedly arranged the march.

The group began to get busy again.

Aside from the loss of the outlying houses at the inn, the caravan was not damaged in this incident.

The people of the post station cannot be evacuated for the time being, and they will have to wait for the officers and soldiers of Zhichong Prefecture to come and find out the latest situation before they can decide on the next step. However, according to their estimates, even if the thieves make a comeback, they will not dare to attack the official post station in broad daylight, and the Liu family's caravan is gone, and the thieves will lose their target, so there is no need to fight the government to the end.

The caravan was about to depart, and Yang Yun called Lei Jiao aside to speak.

Reggio had a solemn expression, and with his old scheming, he had already sensed the existence of spies in the ranks, and he had leaked the news that the caravan had a powerful fire charm in time.

Otherwise, the thieves will be able to win tonight, and it will never be possible to retreat easily without trying to launch a wave of attacks.

"Thanks to you this time, Brother Yang."

Reggio said with a look of gratitude.

Yang Yun said with a smile: "As Zhang Er's master said, the thieves don't know that we have a fire charm, how dare we take credit for it?" ”

"Alas!"

Lei Jiao sighed faintly and didn't say anything, obviously in front of outsiders, he didn't want to expose his family's shortcomings and expose the conspiracy inside.

Yang Yun said: "Lei Dangjia should be careful...... On the way north on this trip, there may be trouble, and people's hearts are separated from their stomachs, so they can't help but guard against it. ”

"Huh!?"

Lei Jiao glanced at Yang Yun, as if he understood Yang Yun's reminder, but he was not very sure, and he was even more puzzled, but because Yang Yun behaved differently everywhere, it may also contain other deep meanings, so he felt more and more that Yang Yun was not a simple person, and he had to treat it well in the future.

Yang Yun smiled and said, "But I believe that after this incident, the caravan will work more together and no longer blindly retreat in the face of difficulties." ”

Lei Jiao nodded and said, "Brother Yang, you said that you once led the soldiers and horses to fight against the Nanban, but there is ...... such a thing."

Yang Yun shook his head at first, then nodded, with a secretive smile on his face, Lei Jiao was also knowledgeable and interesting, and did not ask any more questions.
