Su Lu and his party went up the city wall.

The black flag army ran around the city wall, looking for the birds in the sky that released the arrows.

"Lord, in the direction of Longya mountain in the northwest, I found something in the sky."

Ma Ping found black spots in the northwest sky.

When they looked to the northwest, they saw a big guy with wings stopping in the sky not far from the top of Longya mountain.

Hello everyone, the upper two wings are flapping constantly, and the speed is very fast. Under about a room sized house, there are many arrows flashing cold light. Arrows are constantly shot from under arrogant guys and fall among the Qin army scouts scattered and fleeing below.

Su Lu is stupid. Is this a plane? Airship or something?

The fuselage made of wood, white cloth

It\'s too far away to see what makes the wings, but it\'s too mysterious.

Since coming to this world, Su Lu has finally met a thing that can subvert his three outlooks. Now people\'s scientific and technological level can also fly into the sky.

"Go and have a look."

Su Lu said.

A group of generals immediately surrounded Su Lu. There were so many arrows that they could not die or be disabled. Su Lu, the sea god needle of the state of Qin, must not go into danger.

Xiang Chong said with a resolute face, "Lord, what do you want to see? Just go and see it at the end."

Cao Bao also stopped Su Lu: "Lord, no, this big bird carries too many arrows. If you go, you won\'t be able to make a good deal. In case there are three long and two short, we\'ll be finished."

As a close Minister of the Qin emperor, Cao Bao knows how much the Qin emperor values Su Lu. In order to keep Su Lu, it can be said that the people around Su Lu have risen to heaven because of Su Lu. If he has three advantages and two disadvantages, it\'s good.

Zhao Shuo also said, "Lord, we don\'t need to pay attention to this big bird. He\'s very slow. We just need to hang the barbarians."

Sulu shook his head.

"I\'m afraid not. The barbarians transferred this kind of thing to cooperate with the infantry to attack the city. We won\'t be moved. I\'m afraid it will fulfill their intention. When the barbarians come to the city, we\'ll have a complete rest."

Several people immediately thought of the scene. The big bird flew above the city head, shot countless arrows, swept away the sergeants who cleared the city head, and the barbarians who rushed to the city head easily occupied the city wall.

The city was quiet, and everyone thought of the tragedy when the city was broken.

Su Lu kept looking at the big bird and wanted to see how fast it was, how high it could fly, how many arrows could be fired at one time, and how long the interval between two shots was.

Cao Bao\'s voice sounded: "Lord, you are the Wuqu star in the sky and the God of war on earth. There must be a way to deal with this thing."

Su Lu Xindao naturally relies on anti-aircraft guns to deal with aircraft. Now we have aircraft Qi ā Ng none, anti-aircraft guns with wool.

His eyes unconsciously swept the crossbow bed on the city wall. Su Lu had an idea. It seemed that this thing could crash Qi ā Ng to use.

Asked Xiang Chong nearby, "how big is the largest crossbow bed among the barbarian weapons we seized?"

Xiang Chong looked around, reached out and took a long shot from the side army standing at the head of the city Qi ā Ng, weigh it up.

"The thickness and length of the launched arrow are the same as this Qi ā It\'s almost the same. The thief is far away, thousands of steps. "

Su Lu nodded. In this case, there are still some fun.

However, if you want to choose a reliable shooting location, you can\'t do it at the head of the city. Once you get to the head of the city, the big bird will certainly raise the height, and the range of the catapult may not be able to reach.

We must choose the only way for a big bird and set an ambush high enough to kill the big bird in one fell swoop.

"Come here, find some good shooting crossbow soldiers and order them to shoot birds with crossbows. They must be trained to shoot birds with crossbows."

"Scouts are everywhere. Don\'t meet these big birds and barbarians. Record the marching route of the big bird, especially the mountains and slopes."

Su Lu ordered.

All the generals and schools took orders and carried them out quickly. At the head of the city, only Su Lu and Cao Bao were left.

Cao Bao asked Su Lu, "Lord, did you just issue those military orders to kill these big birds?"

Su Lu pointed to the wounded Scouts under the city, "why not? Since the barbarians dare to beat my people, I can\'t beat his people."

"Besides, this may be the supporters behind the barbarians. I want to see what ethnic group has given such great support to the barbarians and provided such excellent weapons."

Cao Bao looked surprised: "we, can we shoot down this big bird?"

Su Lu narrowed his eyes and looked at the big birds in the West. His tone was indifferent: "if Grandpa Cao wants to, I\'ll show you a ground air defense war."

Cao Bao is ignorant. He knows the ground. He also knows what war means. He also understands anti air, but when combined, he will be blind. What does NIMA mean.

However, it sounds like the force is high enough, and the Lord invited him to stay. He doesn\'t look at it for nothing. After reading it, he can still talk to his majesty and make his majesty happy.

Twelve days later, the barbarian army regrouped and came to Longya mountain and tushanzi again. They set up two camps in two places and made a posture of attacking western Liaoning at any time.

The barbarian scouts went around and cooperated with the big birds in the sky to search for the Qin army scouts. They wiped out almost all the Qin army scouts and made the Qin army completely deaf and blind.

Zhao Shuo presided over the military conference in the governor\'s office of western Liaoning.

Su Lu pointed to the defense map and said the barbarian intention.

"The barbarians who came here this time are much less than last time. The big birds in the sky are the ones who worry."

"With the information these days, the flight route of the big bird has been basically determined. Ladies and gentlemen, I will organize a ground air defense war in the near future to completely kill the big bird of the barbarians."

"This is huzuizi mountain. There is a high cliff on the mountain, which is easy to defend but difficult to attack. The big bird has landed here twice for repair. I intend to set up an ambush here and transport the crossbow bed to four platforms, so as to kill the big birds of the barbarians in one fell swoop."

Zhao Shuo frowned: "Lord, you\'re not here. Who will preside over the war at the head of the city?"

Su Lu shook his head: "if I can take the big bird on the top of the mountain, do you think the barbarians will attack Liaoxi?"

"If my guess is right, once I shoot down the barbarian birds, the barbarian army will immediately turn and go straight to huzuizi mountain and will not attack western Liaoning. As long as I can keep huzuizi mountain, I can survive."

Cao Bao\'s face was eager to try:

"Well, a family led the bodyguard and the black flag army to accompany the Lord to huzuizi mountain. Together with the Lord, they shot down the birds of the barbarians and wiped out the barbarians\' attack on the mountain."

The two leaders spoke, and the generals didn\'t even have the right to refute. A few thoughtful people could only think about what kind of bed crossbow they should take. They should take more crossbows and arrows. In the face of barbarian attacks, how many arrows should they take to block them.

Su Lu ordered, "the barbarians will attack the city tomorrow. Tonight, they will transport the crossbow bed up the mountain all night. They must be in place before dawn tomorrow."

When Su Lu rose, he looked at the crowd and said: "the city must defend well. When I am away, I will be in charge of the whole army and Zhao Shuo."
