Although he was extremely reluctant in his heart, Ma Jingchen still ordered 30,000 troops to enter the pit and began to rescue the injured Tang army after investigation.

After watching the 30,000 army enter the pit and start the rescue, the attack of the Xu army at the head of the city gradually stopped, of course, this is not that the soldiers of the Xu army can't bear it, but Wei Chao and Wei Chizhao and other generals of the Xu army, so that the 30,000 Tang army will not be startled and let the 30,000 Tang army flee in panic.

The so-called big pit is not really a huge hole, and it is basically impossible to hollow out a huge area and keep it as it is, not to mention a thousand years ago, even if it is the current means, it is extremely laborious.

Therefore, when Xu Jun was digging, it was like an ant digging a hole, digging a huge tunnel in the ground, so as to maintain the stability of the ground.

Therefore, after the Xu army destroyed this place, the whole land was like a trench washed by a lot of water, one after another, and it was extremely ugly.

Although in this case, the original Tang army was not completely wiped out, but it also caused great difficulties to the rescue work, the rescue of the Tang army wanted to rescue the wounded Tang army, only by crossing the uneven trenches, can the injured Tang army be rescued, this kind of work is not only time-consuming and laborious, but also extremely dangerous, which is why Ma Jingchen is unwilling.

"Hurry up, hurry up, hurry up, go in, you all go in, you all go in, so-and-so is done."

Watching the 30,000 Tang troops walk into the pit one by one, Wei Chao and the others at the head of the city were extremely excited, and they couldn't wait to stuff all the 30,000 troops into the pit at once.

Unfortunately, things in the world often backfire, and the more you want to do something, the more difficult it is to achieve.

Just when the 30,000 rescued Tang troops were about to enter the big pit, an accident appeared, and I saw a Tang soldier, for some reason, hurriedly ran out of the big pit, and then rushed to Ma Jingchen's side, and after anxiously saying something, Ma Jingchen suddenly ordered the withdrawal of the army.

Seeing that the Tang army that had just entered the big pit began to retreat quickly, whether it was Wei Chao and others or Li Xiaoyi and others, they were extremely confused, Li Xiaoyi and others were just helpless, but Wei Chao and other generals of the Xu Army, who had already taken advantage of this opportunity to inflict great damage on the Tang army, became anxious, and in desperation, they could only launch an attack in advance, but unfortunately, the effect of this attack launched in advance was very different from the budget.

And let Xu Jun miscalculate, Tang Jun saw that the reason for the huge loss was one person, a little person that no one could imagine.

Cheng Tongen is a small person, among the hundreds of thousands of Tang troops, he is just the smallest petty officer, the fire chief, even if it is a fire chief, this is also Cheng Tongen spent ten years in exchange, three of which almost died, seven or eight times almost disabled, but that's it, he also survived hard, with the merit of beheading the third level, he has changed from a slave to a fire captain of the leopard Taowei in the sixteen guards of the Tang Dynasty, which can be regarded as a small achievement.

Being able to change from a slave to an officer, although he is only a petty officer, it can be seen that Cheng Tongen is also a very courageous person, so when he rescued the injured Tang Jun this time, he was the first group of people in today's big pit.

As soon as he entered the pit, Cheng Tongen felt that something was wrong, and then after careful identification, he finally affirmed that the ground in the pit was sprinkled with a layer of fire oil, and this discovery made him extremely frightened, at first he also thought it was his own illusion, but after repeated verification, he knew that his judgment was correct, although the smell of fire oil spilled on the ground was very light, but he could still clearly smell the extremely familiar smell.

The reason why this is so is related to Cheng Tongen's life experience, and the reason why he became a slave can be said to have a very close relationship with this oil oil.

You must know that in ancient China, from the earliest historical records of the Zhou Dynasty, when people ate oil, what they ate was not the vegetable oil that everyone is used to now, but all kinds of animal fat, and fried lamb and suckling pig with butter in spring; fried pheasants and dried fish in dog oil in summer; frying veals and fawns in lard in autumn; In winter, fresh fish and geese are fried in mutton fat.

Of course, this is all about the fat used by the aristocracy, and because of the difficult life of the common people, they eat lard, which is extremely common and extremely rich in fat.

As for vegetable oil, although it appeared in the Han Dynasty, the common people did not consume it, but used it as a tool to use it when weaving cloth or doing other work.

The Chinese people really began to use only vegetable oil as edible oil from the beginning of the Song Dynasty, in the Song Dynasty, although the emergence of stir-frying, ordinary animal oil has been unable to meet the use of dishes, people found that the benefits of vegetable oil.

In the early days of the Tang Dynasty, vegetable oil was more than weaving, and defending the city was also the best item.

And the reason why Cheng Tongen is concerned with this oil is also because of his family's inheritance profession, everyone knows that the ancients paid attention to the succession of the father to the son, that is, what Lao Tzu does, what the son also does, this kind of public opinion is extremely correct.

The ancestors of the Cheng Tongen family have relied on oil extraction for several generations, and animal oil definitely does not need to be pressed by them, they are pressed by vegetable oil.

With the inheritance of several generations of the Cheng family, the Cheng family, who don't know that generation, discovered by chance that this vegetable oil is also edible, and even tastes much better than animal oil.

At first, it was only the Cheng family who used these vegetable oils themselves, but later, after the surrounding neighbors knew about it, they also began to eat it, and as more and more people ate it, the Cheng family's fame became more and more famous.

And after Cheng Tongen's father's generation, his father has done the work of pressing oil to the extreme, he not only uses some conventional plants to squeeze oil, he also likes to choose some unconventional things for oil extraction, if these things are a hobby, it is understandable, but he always gives these newly pressed oils to people to eat, once or twice, no accidents, count him lucky, three or four times no accidents, that is, his ancestors have accumulated virtue, but after a long time, there will always be accidents.

Sure enough, after squeezing the new grease again, something happened, and it was not an ordinary trivial matter.

In the state and county of the Cheng family's hometown, there was a county order again, and the county order had an old lady, who believed in Buddhism very much, and swore not to eat a little meat for the rest of her life in order to believe in Buddhism.

And this county order is also a filial son, so he asked around, trying to find a good way to get the best of both worlds, and finally, in a person's mouth, I heard about the Cheng family's pressed vegetable oil, and the county order thought that since this kind of oil is pressed by plants, it is not considered meaty, and the old lady can eat a little oily things, which is always good for her body.

In this way, the county order came to Cheng's house to ask for vegetable oil, and when the Cheng family heard that it was his parents' official who asked for it, Cheng Tongen's father was extremely excited at that time, and selected an extremely precious good oil from his collection.

After getting this kind of oil, the county order was very grateful to the Cheng family and brought the oil back, and the Cheng family was also extremely excited, thinking that they had climbed the county order, and they didn't want to do whatever they wanted in the future, but they were too optimistic, and no one thought that this was the beginning of the disaster.

Early the next morning, the Cheng family was surrounded by the government's arresting officials, and then from top to bottom, everyone in the Cheng family was arrested and put in prison.

This sudden change made the Cheng family frightened and full of doubts, not understanding what was going on, and it was only after a few days that they finally understood what had happened.

It turned out that after the county order brought the oil back from Cheng's house, he immediately asked people to make dishes and send them to his wife, but he didn't expect that soon after his wife finished eating, he began to have diarrhea, not a general diarrhea, but like the water of the Yellow River flowing endlessly, no matter what doctor, what means are used, this diarrhea is difficult to stop, the original county order of the old lady is a frail and sick person, in such a wild discharge, how can he hold on, and finally rolled his eyes, and his soul returned to the underworld.

The old lady died suddenly, the county order, as a filial son, how to be willing to give up, let people find the best doctors in the city, to explore, what is the reason for his old lady diarrhea, the best, after careful research, several doctors found that the county order of the old lady is because of eating something that irritates people's bodies, so the diarrhea does not stop.

This is easy to find, it is best for the county order to target the oil sent by the Cheng family, and after the exploration of many doctors, it is also determined that this oil is the culprit that makes his wife have diarrhea.

It turned out that the kind of oil that Cheng Tongen's father gave to the county order was nothing else, it was made of castor beans, everyone knows that although castor oil looks very beautiful, but he can't be eaten, not to mention that it is a sick person like the county lady, even if it is a normal person, after eating castor oil, I am afraid that he will also get seriously ill.

found the murderer, although the Cheng family did not deliberately kill their mother, but how could the county order let the Cheng family go, in anger, sentenced all the men of the Cheng family to death, and all the female dependents were mismatched, and Cheng Tongen was not able to carry out the death penalty because he was less than three years old at the time, so he was turned into a slave and distributed to the frontier with the female dependents.

It is precisely because of this that Cheng Tongen is extremely sensitive to the smell of oil, and he can feel the slightest smell of oil.

Therefore, after the first batch entered the pit, after Cheng Tongen found that the bottom of the pit was full of grease, he immediately noticed that this was probably a conspiracy of Xu Jun, and in a hurry, he hurriedly jumped out of the pit and reported everything he found to Ma Jingchen, which led to Ma Jingchen's extremely hasty retreat order.

It's a pity that even if Ma Jingchen's order was timely, he was still one step late in the face of Xu Jun, who had already begun to act.

"Whoosh"

With the sound of a piercing arrow breaking through the air, a rocket was fired from above the city into the crater.

"Boom, boom, boom......."

The flames suddenly appeared out of thin air, and in the blink of an eye, they burst up from the ground, and not only that, but the entire huge pit was soon completely covered by the flames.

"Ahh......h

"Help me, help me, I don't want to die, I don't want to die!"

"Hurry up and save me, I am the son of the Hou Ye, whoever will go up, I will let my father give him a third-level promotion."

.............

A voice, a sentence, or pain, or sorrow, or howling sound sounded from the pit of the raging fire, accompanied by the sound of the Tang Army soldiers who were struggling in pain in the fire, constantly rolling but being chased by the fire and having nowhere to hide.

thought that the terrain in the big pit was narrow, and most of the Tang soldiers didn't even have a place to hide, and without anyone's help, it was tantamount to climbing the big pit, which was tantamount to climbing to the sky, so at the moment when the fire started, all the Tang troops who stayed in the pit basically became fire men.

"What's going on, what's going on, where did the fire come from, how could it suddenly catch fire, could it be that Xu Jun really understands witchcraft, otherwise how could they suddenly let such a fire rise in the pit."

Looking at the sudden sky-high fire in the big pit, Li Xiaoyi couldn't maintain the calm expression just now, and shouted with great surprise and fear on his face.

Compared with Li Xiaoyi's panic, Wei Yuanzhong on the side was full of pain and sorrow, and the thing he regretted the most now was why he didn't desperately block Li Xiaoyi's rescue order just now, otherwise, more than 10,000 innocent Tang troops would not have died tragically under the fire.

It's a pity that by now, any remorse and pain are useless, for the more than 10,000 Tang soldiers who were caught in the sea of fire and were about to die, these things could no longer be exchanged for their lives.

"Chief, haven't you seen it clearly, it's not that Xu Jun will use witchcraft, but that they have already buried the fire oil under the big pit, that is, when waiting for our soldiers to go to the rescue, they suddenly ignited the fire oil and let them die in the fire, giving us the greatest damage." Wei Yuanzhong said bitterly.

"What, this..... This..... This is impossible, how is this possible, how can they hide fire oil in the big pit, this is absolutely impossible. Compared with Wei Yuanzhong's pain, Li Xiaoyi was more afraid and panicked in his heart at this time.

Fear is inevitable, in this extremely powerful situation, he actually lost more than 20,000 elite soldiers, but there is still no Huaiyin City, if he is sued by someone with a heart in front of Wu Meiniang, his fate will definitely not be so good.
