Seeing that the southern army broke a hurdle in the pit so quickly, Qin Yu didn't feel strange, the defending side was like this, and it was okay to delay if it could, and it was not a requirement to win, in terms of strategy, as long as Jinan City was taken, it didn't matter if Dongping was lost, of course, the best ending was that Jinan was taken, and Dongping could be saved.

Qin Yu didn't think about it so much, as long as he ensured that his city gate building was not breached, Dao Yan said that Zhu Di had a big game of chess to play, and it had nothing to do with him, he didn't have any big ambitions, and he was a knighthood and official position with a high position and few things, and Qin Yu was too lazy to do the things that hung his head on his waist every day, and now he was forced to be on the cusp of this storm, and he could only do his best.

At this time, the southern army has already launched the second round of attack, looking at this time in order, the sword and shield hand is covering the advance, even if someone in the front line falls, someone in the back will immediately fill the vacancy, but Qin Yu is clear, the first time is just a temptation, now, it is the real thing!

No matter if you are real at every turn, if you want to break the city, you have to fill it with human lives. However, at this time, the artillery and the eight-bull crossbow that can pierce the shield were not allowed to be used, and the casualties of the Southern army slowed down, of course, the dense arrow array was not so easy to match, and from time to time unlucky guys were shot into hedgehogs.

Looking at the southern army that was gradually filling in the huge pit, Qin Yu evoked a sneer, turned his head to the herald and said, "Dump out what I asked you to do as planned!" ”

...

The soldiers who crossed the huge pit carried the ladder passed up from the rear formation, and they were about to attack the city, and when they were about to set up the ladder in the rain of arrows, the sergeants suddenly smelled something like fire oil, but it was not like it!

Before they had time to think, everyone was ready to go to the city under the urging of the chief!

Qin Yu, who was standing at the city gate, smiled coldly and ordered loudly: "Release the rocket!" ”

"Whoosh, whoosh,"

The rain of arrows wrapped in sackcloth and oil was lit by the soldiers who supported them, and they rained down on the outside of the city.

"Boom!"

The sky-high fire burned quickly under the ignition of the rocket, and the entire area within the huge crater became a purgatory on earth! And the tower of the city gate is still throwing dry wood to the ground!

The soldiers who entered the front line couldn't run, screaming and rolling, and the burning sound of skin and flesh piercing and pulling continued to reach Qin Yu's ears. At the same time, the captain of the front formation realized that the entire range of a hundred paces had been densely dug into small ditches! It's not big, but it covers the entire city gate and the huge pit!

"How did you cause such a fire!? Even if it is oil oil, it will never be so powerful! Zhang Lin scolded angrily.

But no one answered him, and the entire Southern Army fell into a terrible silence, Zhang Lin naturally didn't know, and no one in the entire Southern Army knew! Such a fire is naturally the credit of Qin Yu!

As early as when he inspected the gunpowder workshop, Qin Yu discovered what the so-called fire oil was! It's simply the oil of the afterlife! And it's unrefined crude oil! Just this thing, the general fire is small, and it can't be ignited, let alone can be used as a weapon for siege and uprooting, and I don't know what those Shangguan think, there are so many such things in reserve!

But can this little thing stump Qin Yu, who graduated from science and engineering? Naturally, no! However, in two days, a set of refining tools was established in the workshop, and the oil with a very low ignition point was refined in a similar way! Suddenly, Qin Yu was shocked as a celestial, and this kind of fire oil, under Qin Yu's request, rushed to work day and night, and produced a lot of fire oil in large quantities!

And Qin Yu ordered his soldiers to dig a lot of ditches densely under the city, although it was not big, but it was a lot of victory, and the southern army that was caught off guard suffered a big loss!

The sky-high fire reflected the sky into a different kind of fiery red, and the soldiers who rushed into the front at this moment had no longer wailed, and they went to see Lord Yama, but it was the suffocating smell of barbecue that made Qin Yu not hold back and vomit on the ground.

Looking at the fading Southern Army, Qin Yu eased up and got used to the pungent smell of the barbecue, then waved his hand and said, "If you throw any firewood, save me some use!" Didn't you see that the southern army had all retreated! ”

For this battle, Qin Yu launched tens of thousands of soldiers, and all the trees on the hill outside the entire west gate were cut down, although the fire oil is good, but the burning speed is too fast, if you don't add firewood, I'm afraid that the dead will be extinguished, but there are not so many finished fire oil in the city to squander!

The mountain where Zhang Lin is located is bare, and Zhang Lin, who has just arrived, didn't think so much, the city defense battle should have cleaned up all the obstructions in the place where he could see, and cutting down these books was also the meaning of the title, but he didn't expect to use these things to make a collective incinerator for the Southern Army!

Zhang Lin, who ran away again, looked very angry, but in half a day, it didn't matter if the city gate was not captured, and after two attacks, he lost no less than 5,000 people, just like that, he lost one-eighth of the entire subordinate army! , such a combat attrition rate, in a few days will have to be collectively reimbursed!

If you run out of heads, you haven't been able to take Simon, and you can't say it if you don't be beheaded and shown to the public! What's more, it's still such a mound-like city gate!

Zhang Lin, who had calmed down for a while, slowed down his tone a little and asked, "Have you checked out, who is responsible for guarding the West Gate!?" ”

Lieutenant Xiang Jiang, who was in charge of intelligence gathering, cautiously glanced at Zhang Lin, who was staring at him, and then said: "According to the report of the spies in the city, the person in charge of guarding the west gate is a young man named Qin Yu who just joined the Yan army not long ago!"

Zhang Lin stared at Xiang Jiang coldly: "Young man? Tell me, how young? ”

Xiang Jiang hurriedly lowered his head and said, "It is said that he is only thirteen years old!" ”

Zhang Lin stood up suddenly, lifted Xiang Jiang's collar, widened his eyes and said angrily: "You mean I can't even help a thirteen-year-old hairy boy!?" ”

Xiang Jiang panicked, so he had to say in a loud voice: "General! Checkmate! That was not what I meant! I'm just talking about it based on intelligence! ”

A cadre of generals was looking at the two of them, Zhang Lin felt out of shape, threw off Xiang Jiang, paced back to the main seat, and then said: "Tell me, what's going on with this Qin Yu!" ”
