Although the defense line of the Yalu River in Goguryeo has not yet been completed, it still has a certain scale intermittently, and the Yalu River is not big or small, and it is not small to say that it is not small.

Not to mention, although the trebuchet is a little less accurate, at least the range is barely enough, and the blind cat can still run into a dead mouse, how can there be two or three out of a hundred that can hit the ship.

Although this thing can't even smash the deck of the ship, it can kill people if it hits the head occasionally.

"Big brother, what should I do, do I withdraw."

Generally, large building ships have catapults, but Qin Hao's sea ships do not, and their longest-range weapon is a siege crossbow, which is a little farther than a catapult, so now they are beaten and do not fight back.

As for moving forward, it is even less cost-effective, the big arrows with the thickness of the arms of the siege crossbow are not suitable for hitting them, and they may not take advantage of it if they shoot with bows and arrows, so Pei Xingjian suggested withdrawing first, there are so many places along the coast that can go ashore, I don't believe that there are catapults everywhere, and it is just a matter of harassing them in another place.

Qin Hao said, "Withdraw? Why withdraw, let them smash! ”

Pei Xingjian frowned and said, "Then you have been beaten like this and don't fight back?" ”

Qin Hao said with a smile: "Let them go, this stone will not be conjured out of thin air, think that these stones must have been quarried from the mountain for building fortifications, we were originally delaying time, and now they are throwing the materials into the river themselves, why not." ”

Pei Xingjian suddenly realized, he didn't expect such a simple truth for a while, but he was still a big brother in the end.

He always felt that the stones on the mountain were not valuable, but their boats, and they were all real money when they broke every corner and corner, but he didn't expect that the stones also needed time to be quarried, and for the defense line of the Yalu River, the most precious thing was time.

So everyone was explained in this way, but one by one they all settled down, and the large army went back to the cabin to hide first, and there were people next to the people working on the deck holding some shields, smiling and admiring this rare meteor stone shower, and the sound of those smashing on the deck was regarded as accompaniment.

Soon, the guards on the shore also discovered this problem, because the stones they used to repair the fortifications were almost finished, and the guards reacted to the smell and their faces turned green.

"General, they don't seem to dare to go ashore, I heard people say that the sailors of the Tang Dynasty are actually just relying on the high sails of the ship, and the overall quality is not high, they are all gangsters, I think they can't fight a tough battle on land, or let's leave him alone and continue to repair the defense line."

The guard general also moved when he heard it, and he had also heard the news, and now the construction period is very tight, and if the progress can't keep up, he will be killed.

"Yes, then leave eight hundred men on the shore to stand on guard, and the others continue to work, as if they don't exist."

As he spoke, the guard also glared at Qin Hao and their big ship hatefully and left.

And all of this was clearly seen by Qin Hao with a telescope.

The principle of the telescope is not complicated, it's just that there is no glass, and Qin Hao will definitely not do it, but now that all the strange goods in the world are out of the Green Gang, it is not difficult to find a little high-transparency natural crystal under the careful attention.

Then, Qin Hao used his telescope to keep staring at the Goguryeo soldiers who were arrayed on the shore.

On a cold day, in front of the rushing river, who can have much patience? After a while, the formation was scattered, and in less than an hour, the formation became bustling, and the Goguryeo guard saw that Qin Hao really didn't dare to go ashore, so he simply pulled out hundreds of them and went to work.

At this point, there is almost no formation to speak of.

After showing the telescope to Pei Xingjian and Wang Fangyi, they also said that it was an opportunity, so Qin Hao decisively ordered to approach the shore at full speed.

Just in time for the tailwind, although the speed in the river is not as fast as in the sea, they are not far away, and when the defenders find out that Qin Hao and them are approaching, it is obviously too late to organize a formation.

Flutter~

After Qin Hao and the others drove to the shore, they began to shoot at the defenders from high and low, because the defenders had no formation, and there were only about 500 people, and they were especially thrown from low to high, so it didn't take long for them to suffer heavy casualties.

Seeing that the hundreds of people were almost dead, Qin Hao immediately ordered: "Change the rocket!" Projectile, burn their fortifications. ”

So, there was another flutter, and then it began to whirring and whirring.

The fortifications of the Yalu River defense line have a large number of wooden structures, although they must pay attention to arson treatment when repairing, but this has not been repaired yet, and for a time this ignition forced them to be in a hurry.

After about seven or eight rounds of shooting, seeing that the defenders finally organized themselves on a large scale and rushed over, Qin Hao laughed and said, "Withdraw!" ”

So, after the defenders lined up on the shore, Qin Hao's boat ran out of their range again.

"I'm mad at me! It's so arrogant, get me a stone and shoot them. ”

"General, didn't you say that it was the material for our fortifications?"

"I don't care, anyway, this project will definitely not be completed on time, in a month Lao Tzu will move his head, and he is going to die, who is this for, shoot! Shoot! !。 me ”

Poor child, after such an afternoon's hard work, he was almost driven crazy by Qin Hao and them.

As for Qin Hao, he found that this kind of harassment seemed to be quite useful, anyway, they were invincible on the water, as long as they didn't go ashore, they could play any tricks they wanted.

Harassment, it's a bit of a waste to pile up more than a dozen ships here, so Qin Hao simply divided his troops and took out ten ships to transport supplies to Li Shimin and Niu Jinda, and the rest were all scattered.

So, for a while, the entire Yalu River was full of scolding voices, and the fortifications were repaired at a speed like a turtle, and after they dispersed, these gangsters made all kinds of tricks to damage.

For example, some people choose to sleep during the day when you are on full alert, and do not attack at night, just beat gongs and drums on the river surface and do not let you rest, and then go to your door to set fire to it when it is dawn in the daytime, and after three consecutive days, the project cannot be repaired even an inch, and they have burned a lot.

What's more, he actually used the feces and urine saved on the boat to shoot at the defenders with a siege crossbow, and when the uncomfortable defenders worked, it was like working in the toilet, and some of the guards with a relatively large temperament really couldn't stand Qin Hao and them, and they probably thought that they would also die after a month, and they actually rushed into the river with people holding a real sampan.

Of course, these not-so-good-tempered guards must have to feed the fish in the end.

When Li Shimin learned of Qin Hao's actions, he laughed happily, and now that the Tang Dynasty soldiers are like a rainbow, he believes that it won't be long before he can reach the Yalu River.

"Well done, although Zhenheng is young, but he is really a master of the art of war, I want to break the Yalu River, pull out his Pyongyang City, erase Goguryeo from the map, tell him, do a good job, after returning to Beijing, I will reward him with merit, I want to crown him as the prince of the country."
