When Pei Xingjian was in Chang'an, he once told Wanniang about his experience in Liaodong, one of which he had mentioned many times, that is, when attacking Goguryeo, he could only eat cold food and eat dry food in some special circumstances, especially in winter, not to mention that kind of taste.

Pei Xingjian said that he had no intention, but Wan Niang was the listener's intention, so she came up with a way to heat the lime, she wrapped the lime tightly with paper, so that she usually didn't have to worry about leaking out, and sewn it with a cloth outside to make it easy to carry, and when she used it, just pour water, although the heating temperature is not high, but at least let Pei Xingjian eat a hot meal.

However, because Pei Xingjian was in a bit of a hurry, he didn't have time to take these things away, and later Wanniang asked Li Xiu to help send these things to Liaodong, that is, when Pei Xingjian was ready to come out this time, he received the things sent by Wanniang, so he brought some lime wrapped on his body, but he didn't expect it to be really easy to use, and even Su Dingfang followed him to eat.

After a while, the canned food was heated, and at that moment Pei Xingjian handed the canned food to Su Dingfang, and took another bottle of canned food and put it in, after all, he didn't bring many lime bags, and he didn't know how many days he was going to stay in Goguryeo, so he naturally had to save some money.

Su Dingfang was not polite, and smiled and picked up the stopper of the can, which was oily braised pork, if it was not heated, this thing would be cold and greasy, and even a little fishy, but now it is fragrant, and it feels all warm up in one bite, if there is a little more wine at this time, it would be great, but unfortunately alcohol is forbidden in the army, and he, the main general, is no exception.

After eating, the sky outside also darkened, Pei Xingjian arranged for some people to take over the people who were patrolling outside, although the possibility of the grain transport team rushing at night was not high, but they could not be careless, not to mention that they had to beware of the enemy's discovery, so they had to be cautious at all times.

The night passed very peacefully, and early the next morning, Pei Xingjian immediately sent additional men to inspect the surroundings, and Su Dingfang also ordered the whole army to prepare, because the grain transport team may arrive at any time, and they will also face a fierce battle, after all, the Goguryeo people are not stupid, and their grain transport team must also be heavily guarded.

At noon, a spy rushed to report and found a grain transport team approaching in the southwest direction, which made Su Dingfang also mentally shocked, and immediately ordered the spies to probe and report again, and at the same time led the Tang army to sneak out of the valley quietly and ambush in the direction of the grain transport team.

There are more than 2,000 people in the Goguryeo army guarding the guards, in fact, it is not that the Goguryeo people have no one to send, but the more troops they guard, the more food will be consumed on the road, and even if this batch of grain is transported to Pyongyang, I am afraid there will not be much left, so when transporting, only when the border will send more troops, and after leaving the border, they will try to reduce the manpower and reduce the consumption on the road.

Su Dingfang, as a general in the army, naturally knew the above situation, so he would venture deep into the interior of Goguryeo, in order to let the Goguryeo people relax their vigilance, in fact, he was also right, although the team in front of him was comparable to them in terms of strength, but according to past experience, in a field war, a Tang army can reach four or five Goguryeo soldiers, which is mainly because there is too much gap between the two sides in terms of equipment, training, morale, etc.

"Kill!" As the grain transport team entered the range of his ambush, Su Dingfang immediately rushed out first, and the two thousand Tang troops also came out, and the shouts of killing resounded throughout the world for a while.

The Goguryeo grain transport team was also frightened by the sudden Tang army, after all, they did not expect to encounter the surprise attack of the Tang army at this time, until Su Dingfang's cavalry was about to kill the front, the Goguryeo general in charge of the escort reacted, and hurriedly ordered his soldiers to set up a defensive formation, hoping to withstand the first wave of impact of the Tang army.

Su Dingfang brought all the cavalry, two thousand cavalry charged, it was like a sea of mountains, the Goguryeo army on the periphery just set up a defensive formation, and met the Tang army in the vanguard, the result was like a sand castle meeting the sea, the defense collapsed in an instant, and then the Tang army was like a sharp arrow to kill in.

"Set fire!" Although the enemy was vulnerable, Su Dingfang was very calm, and immediately passed down the order again after entering the team transporting grain, and then saw that there was a special cavalry in the rear who took out a special fire oil bottle from the horse, lit the fuse on it and threw it to the carriage transporting grain, and the result was that the fire was soaring into the sky in the blink of an eye, and the sound of people shouting and neighing horses was endless.

Su Dingfang's main purpose is to destroy food rather than kill people, even if they have an advantage now, but Su Dingfang is not willing to fight, because their number is limited, they cannot be replenished in Goguryeo, and if they die one, they will lose a little strength, and if they are entangled by the enemy, so that reinforcements arrive, then their situation will be even worse.

It is precisely because of the above considerations, so Su Dingfang led the cavalry like a gust of wind, from the beginning to the end of the army transporting grain, during which the Goguryeo army organized several counterattacks, but he was defeated, and after the grain was burned, Su Dingfang immediately led the army to roar away, and disappeared in the vast land of Liaodong in the blink of an eye, leaving only a place of charred grain and the Goguryeo people with heavy casualties.

This raid was very beautiful, but it also exposed the fact that Su Dingfang and they infiltrated, and as a result, Goguryeo also reacted immediately, mobilizing troops everywhere to surround Su Dingfang's army, it can be said that this is the most dangerous time, but Su Dingfang has already made a plan, just when the Goguryeo people thought that he would retreat in the direction of the Tang Dynasty, he did the opposite, and actually killed in the northeast direction, and burned the grain when he saw it, and seemed to repeat the brutality of previous years.

Su Dingfang's bold behavior also completely angered the Goguryeo people, and at present, countless Goguryeo troops were transferred to the northeast, hoping to intercept Su Dingfang's army, and even the border troops were mobilized.

However, as soon as the Goguryeo army on the border left, another Tang army actually entered from the border, taking advantage of the emptiness of the Goguryeo border, and burned down several granaries in one fell swoop.

However, when the army of Goguryeo rushed to the border, the Tang army that attacked the border suddenly retreated, and Su Dingfang behind him could not be found, which made countless Goguryeo people feel liver pain, but there was no way, and when they finally found Su Dingfang's traces again, the other party had already retreated to the border, and finally took advantage of the night to break through the blockade of Goguryeo and escape back to the Tang Dynasty.

This is only the first harassment attack by Su Dingfang this autumn, and there will be a second and third time in the future, until the army of Goguryeo is exhausted and the harvested grain is also greatly lost, and what is worse is that this kind of harassment war has lasted for almost three years, and the Tang Dynasty is strong, and the price paid is nothing, but Goguryeo cannot afford to pay such a price.

In the city of Chang'an, Li Xiu has also been paying attention to the battle situation in Liaodong, although the invasion of Tubo in the southwest, but Hou Junji's army has set off, with the current combat strength of the Tang army, Tubo has almost no chance of winning, of course, the most important thing is Li Shimin's determination, the reason why he sent Hou Junji to go, but also ordered the other party to annihilate the enemy of Tubo, in fact, there are deeper plans.

The Tang Dynasty's bloodletting policy against Goguryeo has been going on for many years, and seeing that Goguryeo is about to be unable to hold on, there are also internal problems in Goguryeo, the most important of which is the contradiction between King Rongliu and the great pair of Lu Quan Gai Suwen.

The name Quangai Suwen should not be unfamiliar to later generations, because it was he who blocked Li Shimin from destroying Goguryeo, and he was able to block Li Shimin's soldiers, so he was naturally not an idle person, in fact, he was born in a Goguryeo aristocracy, and his father was Goguryeo's Great Pair Lu, which is equivalent to the prime minister of the Tang Dynasty, and he also has military power, which can be said to be above 10,000 people under one person.

After the death of Quangai Suwen's father, he inherited the position of the Great Pair of Lu, but after King Rongliu ascended the throne, he wanted to Goguryeo, and he naturally hated Quangai Suwen, a nobleman who held real power, but it was not easy for him to deal with Quangai Suwen, because there were many real power nobles behind the other party, and as a result, there was a split within Goguryeo.

It can be said that now Goguryeo is in the midst of internal and external troubles, and its strength has been weakened to the extreme by the Tang Dynasty, seeing that Li Shimin is about to harvest the delicious fruit of Goguryeo, but he didn't expect that Tubo in the southwest would jump out to make trouble, which made Li Shimin not hate, so he issued an order to Hou Junji to annihilate everything, in order to teach Tubo a cruel lesson, at least let the other party be honest for a few years, so as not to have anything happen in the southwest when he attacked Goguryeo.

It is in the above context that Li Shimin also invested heavily in Hou Junji's army, especially the supply of firearms is almost open, because the southwest is mountainous, which is not conducive to the cavalry charge of the Tang army, with firearms, it can make up for the loss of the Tang army in combat power, and the Tubo people are almost a group of uncivilized primitive people, as long as Hou Junji is not particularly stupid, there is almost no need to worry about defeat.

Although Su Dingfang's war in Liaodong this year had some twists and turns, it was generally very smooth, seeing that the weather was getting colder day by day, and the war in Liaodong was also coming to an end, but at this time, Su Dingfang suddenly had a hundred thousand urgent news sent to Chang'an.
