It was another early morning, and when the sun was about to rise, Hao Laosan stood above the Wulongling Pass and looked ahead, judging when the Song army would launch a new round of offensive, with deep sorrow and tension on his face.

After a few days of attack and defense, although the Wu army, which had an absolute geographical advantage, almost completely won and suffered very small losses, the pressure on them to serve as soldiers was still extremely great. Every time a sharp arrow came up, he felt his legs tremble, because this was a terrible encounter that he had never experienced before, after all, just a few months ago, he was just a soldier guarding the gate in Muzhou City, and he had never seen such a battle.

But today's Song army camp looked much calmer than usual, and the siege queue was not formed at this time, and it seemed that there was no intention of launching a new offensive immediately, which made Hao Laosan breathe a long sigh of relief. But just as he was halfway through his breath, something that made him unbelievable and thought that he was hallucinating happened again from the Song camp in front of him, and something slowly rose into the air over there.

"That'...... What is that? Hao Laosan unconsciously reached out and rubbed his eyes, but when he took his hand away again, he found that the rising thing was already higher, and the outline was clearer - it was not fireworks, but a weird, huge spherical thing, and there seemed to be something rising below, and it was still coming towards Guancheng little by little.

At this moment, not only Hao Laosan, but also the other guards and generals on the city also saw this strange scene, countless people opened their mouths wide, but they didn't know what to say for a while, they all raised their eyes and stared at the balls flying towards this side, and after a while, there was a burst of exclamation: "Song Jun, what kind of demon magic did Song Jun use...... Quick, go and report to General Fang......"

With this exclamation, some people had already stumbled and ran down, and some people actually tripped and fell down the stairs that were not too steep because of their souls, and the screams suddenly rang out. The entire Guancheng was in chaos in an instant.

For the people of this era, the impact of such things that take off and fly in the sky is really too strong, especially when this thing is raised from the hostile military camp, which puts even more pressure on the soldiers. And looking at this huge ball flickering in the wind, constantly approaching, those soldiers were even more frightened, their faces were as pale as earth, their legs trembled, and even the hands holding weapons were unstable, not to mention that at this time, they thought of throwing arrows at those things, and they could not fall to their knees because of fear, which was enough to prove that these Wu troops were bold enough.

"Demon ...... Demon Law ......" Hearing the news, he came out of his residence, and when he raised his eyes, he saw a large number of round balls coming from the air, and even Fang Bainian was in a panic. But after looking closely, especially when he found the faint figure standing in the huge bamboo basket under the ball, he suddenly felt a stirring in his heart, and shouted: "Give me arrows!" It's the Song Army, they make the demon law want to cross our Oolong Ridge from the sky! Shoot me arrows and shoot them down!" ”

The general's roar still had some effect, and there were crossbowmen who had the courage to shoot arrows at the approaching balls in front of them. But the distance between the two sides was too far at this time, and their arrows couldn't reach it at all, so there was no threat at all. And in this way, the pressure on Wu Jun is even greater, and many people have lost their judgment of common sense at this time, thinking that this is also the relationship between Song Jun and the demon law, so their own arrows have lost their effect, and they are even more frightened to hang down their bows and crossbows, and they dare not move again.

The sparse arrows fell weakly in the distance, so that the huge bamboo baskets were staying, and the elite of the Song army, who also had weak legs and a pale face, had enough confidence in their hearts. But until this time, they still couldn't believe that they had really flown into the air, advancing from the air like the legendary gods, and would cross the high Oolong Ridge and launch a surprise attack on the enemy from the rear.

Rao is these people are the elite of the Qingzhou army who has followed Sun Tu for the longest time, and they are the iron men who came from a hundred battles in the camp, but in this high place that has never been involved, everyone is still afraid, and their eyes are completely afraid to look down, and both sides are all dead on the edge of the bamboo basket, it seems that only in this way can there be an extra layer of protection.

Even the two heroes Wu Song and Luda, who were among them, were pale at this time, and the height of several hundred zhang above the ground had too great an impact on them. Until now, they still couldn't imagine how Sun Tu could come up with such a ...... that could rise into the air and fly forward with thousands of brothers and fly over the high Oolong Ridge

In fact, the answer is very simple, because this is a good thing that Sun Tu found from the system warehouse that is most conducive to their smooth breakthrough of Wulong Ridge.

Just some time ago, as Sun Tu almost unified Jiangnan and won the unanimous approval of the Jiangnan military and civilians, his system warehouse finally opened up a large area again, and let him get a lot of gains from entering it on a whim.

This time, he found a batch of high-quality hot air balloon accessories in the new warehouse.

Originally, Sun Tu still felt that this thing was not as good as gunpowder, diesel or diving equipment, but after knowing that Wulongling was difficult to overcome, he suddenly found that this was God's greatest help to him.

If you really want to forcibly break through the pass, in the face of this dangerous pass of Wulongling, which stretches for hundreds of miles, towering into the clouds, and there is no shortcut, the Song army can do nothing more than two major choices, either continue to attack and rely on human lives to fight a bloody way; Either you can climb up from the dangerous ridge on the side, and then attack with the army in front of you, or you can break the level.

But both require absolute courage and luck, and the price to pay is bound to be enormous. But now it is different, with this batch of hot air balloons that can fly from high altitudes, he can transfer his soldiers and horses from above to the back of Wulongling Xiongguan, and then attack back and forth, this seemingly unbreakable danger will no longer be able to stop his westward footsteps.

Therefore, when others thought that he was still in Hangzhou and was self-respecting, Sun Tu found craftsmen in the city and asked them to build simpler rides on the spot according to that batch of hot air balloons. After all, there is still a disadvantage of hot air balloons, that is, the load capacity is not too large, often only five or six people, so the number of hot air balloons needed to put a group of elites behind Wulong Ridge is quite huge.

Hot air balloons, on the other hand, have their own advantages, that is, they are much simpler to construct than other flying objects in later generations. Even if he couldn't get the ignition device provided in the warehouse, with the ideas and dexterity of the craftsmen of this era, Sun Tu still built a large number of hot air balloons temporarily.

When the last batch of hot air balloons arrived along with the grain and grass, Sun Tu immediately used it, picked out the elites in the trapped camp, and then cooperated with more than a dozen generals who were already skilled in martial arts, and took off and headed towards Wulong Ridge.

Originally, he planned to lead the team himself, but he was still persuaded by the generals under him. In the end, only Lin Chong, Yang Zhi, Luda, Wu Song, and Hua Rong ...... A cadre of generals led the team to set off together, and even Dong Ping did not dispatch. But even so, this time the Song army can be regarded as sending the strongest elite out, and success or failure is also in one fell swoop.

Hundreds of hot air balloons floated slowly forward like a flock of birds, and soon appeared in the sky above the Wulongling Guancheng. But at this time, the distance between the two sides is getting wider and wider, so even if the arrows from below rain, it will be difficult to hurt the Song army above.

On the contrary, it was the soldiers of the Song Army, who had slowly overcome the feeling of fear of heights at this time, and began to fight back, as they bent down and threw out, one by one the round balls whistled downwards like hail in an arc posture, frightening the Wu army below with a burst of screams and dodge.

And these balls were still in the air, and they had already made a loud popping sound, splashing the iron nails and other things filled inside along with the shattered shells, and splashing towards Wu Jun below. Suddenly, countless soldiers of the Wu army were shot by these small pieces, screaming and falling to the ground.

Although the lethality of the destructive bomb is not particularly large, the range of damage formed by this volley explosion is still extremely terrifying. And for Wu Jun, the bigger threat still comes from the fact that this thing falls from the sky itself, because in their eyes, the Song Army that can come from the sky is itself the embodiment of the demon law, and now they have thrown out this large piece of palm thunder, which has destroyed the psychological defense line of Wu Jun in an instant.

Even Fang Bainian and other generals themselves were already full of panic at this time, and many people couldn't care about ordering the whole army to deal with possible attacks from the rear of Guancheng, and everyone was scurrying around like headless flies, and the entire Wulongling Guancheng was completely chaotic at this moment.

The combination of the belief and fear of the theory of ghosts and gods, the infinite pressure of being controlled by the enemy, and the damage caused by the destruction bullets, finally made today's battle even begin, and the Wu army showed a one-sided decline.

At this time, with Sun Tu's order, the sound of the horn in the Song army's formation suddenly rose, and all the soldiers and horses had been pressed up, taking advantage of the confusion of the enemy army, they did their best to launch the most fierce attack on this rare high mountain Xiongguan in the south.

This time, Sun Tu, as the commander of the three armies, did not sit in the Chinese army as safely as before, but took the lead and rushed to the front of the team. The steel knife in his hand was clenched, his body undulated and jumped like a cheetah, and soon he had reached the unguarded towering wall, and with a wave of his left hand, the long rope had been thrown up and climbed up to the top of the city, and the people followed upward.

At the same time, as soon as he looked up again, he saw that those hot air balloons had begun to sink after crossing the Oolong Ridge, and it must not be long before the battle from the rear would begin!
