Wen Lan looked at it and laughed dumbly: "If he is really still a member of the blood clan, it is also a shame that he can come up with this method, and he actually let the cavalry drag the chariot away." "What I thought in my heart was that the two clans of the Blood Blade already had their own strengths, and the results were immediately visible under the combination, and it was not difficult to think of this method, but the difficult thing was to let Qi Lie help Luo Bu.

Su You is right, as long as the three clans work together, they will be able to fall into the city!

Indeed, he was able to convince the people.

Seeing that the well and the artillery cart were moving quite slowly at first, and they were also very disturbed to see from behind, but they suddenly accelerated and galloped forward like a giant beast going crazy, and they all cheered and wondered. At this time, I suddenly heard several eagle whistlings in the array behind him, and it was the double eagles on the shoulders of Eagle Wang Hunying who rose into the air and cried.

The Eagle Clan has always liked to give orders with the roar of the eagle, firstly, the sound can be transmitted far away without interference, and secondly, only the people of their own clan can know the meaning, and ordinary people do not understand its meaning when they hear it.

Hunying let the twin eagles fly over the well and hovered the eagle whistle a few times, and the sharpshooter on the well immediately understood its meaning, and wound his arrows and aimed at the head of the north gate of Linzhou.

The well was much smaller and lighter than the artillery wagon, so it moved faster than the artillery cart and was the first to enter the range of the archers of the defenders at the head of the city.

The head of the city was already full of soldiers, all with white feather arrows in their hands, and when they saw the attack of the well, they immediately shot at the city.

According to Su You's instructions, each marksman on the well had two gold-armored double-shield soldiers in front of him, so he had four shields. Seeing the rain of arrows, the shield soldiers hurriedly recruited their shields to support them in front, only to hear the sound of jingling and jingling, and they had all been blocked.

The archers of the Eagle Clan are very comfortable behind the shield, and they also pick up a few white feather arrows that are shot to their side to take a closer look, and secretly praise that although the strength of this blue sea is weak, the ability to make arrows is not bad, and then maybe you can replace it with this arrow sent now to try your hand.

After shooting for a while, the momentum gradually faded, and when I looked through the gap in the shield, there was a surge of people on the city, as if replacing the soldiers.

The Eagle Clan's eyesight was very good, and when they saw that the newly replaced soldiers were still holding the leather water pipe, they knew that this was the water dragon team that had performed miraculous feats before. Su You had made it clear before that when he saw the crossbowman, he hid behind the shield, and when he saw the water dragon soldier, he immediately shot and killed.

At this time, the rear artillery car had also arrived, and it was precisely because Hu Ying, who was defending the city, saw the artillery car that he hurriedly withdrew the crossbowmen and transferred the water dragon team forward.

Unexpectedly, the water dragon team had just taken place, and the Eagle Clan marksman on the well suddenly appeared behind the shield, and it was also a volley. Although the number of archers is far less than the previous archers at the head of the city, the momentum is not weak. Suddenly, there were screams among the water dragon soldiers, and many soldiers who had been shot by stray arrows had fallen to the side.

Hu Ying saw that the situation was not good, to break the artillery car, the water dragon soldiers were indispensable, and the crossbowmen were still reinforced, but the water dragon team was only one or two thousand people, which was precious.

Seeing that there were a large number of wells, she would not be able to let the water dragon team use the water dragon if she didn't deal with it, so she immediately ordered the water dragon soldiers to take refuge and replaced them with crossbow soldiers.

This time, she ordered someone to replace it with a fire arrow.

Since the well is made of wood, as long as the well is burned, the shield soldiers and archers on the well will naturally fall to the ground.

Seeing the fire arrows coming from the well here, the shield soldiers still raised their double shields to resist for a while, but they found that this time most of the fire arrows were not coming towards people, most of them were shot at the body of the well and the body. Although it was not immediately burned down, I saw that several wells had been burned to black smoke, and the body began to shake slightly.

Rob watched his well catch fire, and suddenly felt a heartache, and couldn't help but want to ask Su You what to do. Su You said with a smile: "Order your artillery cart to aim at the city gate and fire quickly, the harder you fight, the less damage your well will be." ”

Rob had no choice but to take the order, but fortunately the artillery cars were all in place, this time fifteen in a row, alternating in the front and rear, and the firepower was twice as high as the last time. Under the roar, the north gate was bombarded and trembled.

Hu Ying saw that the fire in the well was rising, and the archers on the wall avoided behind the shield, and the artillery car was gradually approaching, so he immediately withdrew the archers and replaced them with water dragon soldiers, wanting to concoct the last water dragon tactics according to the law.

Unexpectedly, the position where the artillery wagon stayed was very tricky, just behind the shaft. The water dragon sprayed over, but before it touched the artillery cart, it poured the well through first.

As a result, all the fire on the well was extinguished by the water dragon, and it was wet from top to bottom, and it was useless for Hu Ying to change the fire arrow to rekindle the well block.

Wen Lan saw from a distance that the water dragon had destroyed the well, and she couldn't help but praise: "The lord of the country is really good." ”

Su You smiled slightly, this is exactly the strategy taught by "Yun Ce". Since ancient times, fire and water have been ruthless and mutually restrictive, and it is not easy to use them on the battlefield at the same time.

"Okay, now is the right time, order Qi Lie to attack quickly."

The cavalry of the blood clan was already ready to go, and when Ali Hai saw the king's banner raised, he immediately shouted: "Array!" Charge! ”

Countless four-man cavalry arrays set up wire nets and streamed out from behind the artillery carts, at first the queue was still wandering around, and the closer they got to the city gate, the more they converged into a line, which was the previous long snake formation.

Standing on the tower of the city were water dragon soldiers, and it was too late to withdraw and change the crossbowmen. Hu Ying simply ordered the water dragon Qianhu to aim at the long row of snakes and ride in a formation to spray.

"Suzaku, forty-two, due north, thirty-five!" The flag in Qianhu's hand waved, and dozens of water dragons suddenly gathered in one place and rushed towards the long snake.

However, Ali Hai looked carefully in the rear, and also shouted: "Points!" ”

A long snake turned into two in an instant, like a doppelganger, and the queue was not the same, and Rob couldn't help but applaud when he saw it on the horse.

At this time, the artillery vehicles concentrated on bombarding the city gate, which had deformed the top of the gate, but the bottom of the gate was still immovable, it turned out that Hu Ying had already piled up the sand and gravel snow at the city gate in advance since he suffered the last loss, and it was far from easy to blow up the city gate.

Alihai's cavalry marched quickly, and in a blink of an eye, the front part of the snake's head had reached the gate of the city, and all the cavalry still untied the clay pots on their waists and piled them up as they did last time.

In a short time, a large pile of black stone oil had accumulated at the city gate, and there were many strange stones mixed in it.

Su You put his hand on the pergola and saw that half of Alihai's cavalry formation had returned to the formation, and immediately shouted: "Please raise the arrows of the Blood Flame King!" ”

Qi Lie responded with the sunset bow and aimed his hand at the city gate with a fire arrow.

I saw that the arrow fell and the flames rose, and immediately the fire burst into the sky, burning black smoke billowing at the city gate, and it was everywhere.

Wen Lan saw that the fire had been burned, and Hu Ying's water dragon team was still spraying at the artillery car, although Hunying's marksman took the opportunity to shoot down a small group of water dragon soldiers, but only five hundred people could go to the well, which was less after all.

After Rob saw that the water dragon team had shot three artillery vehicles back into battle, he was a little anxious, and asked anxiously: "Lord, that water dragon soldier is so powerful, how is it good?" ”

Su You smiled and said, "How can the stone carefully prepared by the Great Witch God be wasted, if she doesn't fall for it, then she will tempt her." Uncle Wang can let the artillery car and the well retreat together, out of the range of the water dragon. ”

Luo Bu couldn't wait for Su You to let him retreat, and hurriedly shouted: "Retreat!" Back off! ”

After shouting, he was still unsatisfied, and shouted at Qi Lie again: "The Blood Flame King also help me, let your cavalry help pull back together!" ”

Qi Lie was helpless, and it happened that Wodar's cavalry formation had all returned, and even the iron rope had not yet had time to return to Ultay.

"Wodar, you can run again and help the Blade Clan drag the artillery cart back."

"Yes." Wordar put the iron rope on the shield, and without saying a word of nonsense, he led his troops out again.

Hu Ying saw the artillery car suddenly retreating, although he didn't know what it meant, but he was secretly glad in his heart. Artillery, wells, and cavalry formations are indeed anxious to greet them together, and now only the city gate is on fire, and only the water dragon can be rescued.

Under Hu Ying's order, the water dragon Qianhu turned the small flag in his hand left and right a few times, and all the water dragons immediately turned around and sprayed under the city gate. At this time, there was still half of the strength of the water dragon soldiers, although the power was not as good as before, but it was still not weak.

Su You and Wen Lan saw the water dragon turning from a distance, and they were secretly happy in their hearts, and the two of them covered their ears in unison.

When everyone was puzzled, they suddenly heard a loud sound like a landslide at the city gate, which shook their ears and buzzed.

Qi Lie and Hunying were mostly war horses and war eagles in the array, and they were so frightened by this sound that the generals on both sides easily cleaned up their positions. Luo Bu was in the array, but he himself was so frightened that he fell off the horse and fell to the ground, and the handle of the golden-ringed goose feather knife happened to poke straight into his waist and eye, making Rob grin in pain.

"Uncle Wang, Uncle Wang?"

Seeing someone stretching out his hand, Rob stood up with his hands in his hands, and when he looked again, he realized that it was Su You. The lord of the country came to help him personally, and suddenly felt that Bei'er had face, and said with a forced smile: "Lord, Uncle Wang, I have never heard such a big movement in an artillery battle, how can it be more powerful than my thunder artillery car?" ”

Wen Lan was very proud when she heard this, and laughed: "Where is this cannonball, this is the kind of gray stone I showed you before." The name of this thing is calcium carbide, although it is not easy to refine, the materials consumed abound. ”

Rob was stunned and asked, "Calcium carbide?" How have I never heard of this? ”

"Well, I also don't know what to do after refining, this calcium carbide is different from ordinary stones, it burns when you see fire, and you see that the water is not only not extinguished, but it is more prosperous, if you use it too much, it will be like just now, burst like thunder, shaking the sky and the earth! This thing is not easy to preserve, can only be placed in oil, just when the lord of the country came to ask me about the siege of the city, I thought if it was added to the black stone oil would not be just right, so it has today's wonderful use. ”

As he spoke, Wen Lan pointed into the distance and said, "Look! ”

Rob looked at the city, only to see that the fire at the gate had not yet dispersed, and the gate had been blown apart and flew into the distance, revealing a full of sand and snow behind the gate.

However, what is surprising is that the right side of the north city wall was actually blown up, and the broken wall and debris fell together, revealing a gap several zhang wide.

The city is broken!

Note: About this inconspicuous and magical gray stone, the correct answer is calcium carbide, which is also known as calcium carbide in daily life (Wen Lan is not nonsense, it is really called this name) Interested readers can Baidu by themselves. Therefore, the offensive and defensive battle in Linzhou can probably be seen as a duel between a physics teacher and a chemistry teacher...... (laughs)
