Liang Xiongfei always thought that he had to become a traitor because he had no choice but to suffer. At that time, the Mongol army marched south, Lin'an fell, the emperor surrendered, and the death of the country was a foregone conclusion. At that time, Xu Zhiliang, the envoy of Guangnan East Road, sent himself to the Mongolian Longxing Marshal's Mansion to ask for surrender, and he was appointed by the Mongols as a envoy to return to Guangzhou and surrender to the prefectures and counties of Guangdong. But at this time, Xu Zhiliang heard that King Yi was proclaimed emperor in Fuzhou, he repented, not only declared himself a rebel general of the Great Song Dynasty, but also sent troops to fortify at Shimen to prevent him from entering Guangzhou.

Shangguan's reversal made Liang Xiongfei feel helpless, but he could only lead the troops and fight. As a result, Li Xingdao fled without a fight, and Huang Jun, the commander of the Destroying Front Army, was defeated and fled back to Guangzhou, but Xu Zhiliang abandoned the city and fled. After Liang Xiong flew to the city, he promised that anyone who surrendered could be awarded an official, but Huang Jun refused, so everyone killed Huang Jun and opened the city to surrender. In this way, Liang Xiongfei was convicted of being a traitor to the Great Song Dynasty, and he couldn't turn back if he wanted to.

Because the education of the people of the time is the unity of the monarchy and the country, what the emperor said and did was correct, so the decline of the country and the darkness of the government were all deceived by traitorous ministers, and the emperor was still a good emperor. The same is true for Liang Xiongfei, he was framed by Shangguan and became a traitor who was spurned by thousands of people, but he helped the enemy to seize the emperor's country, and he was still a little unhappy in his heart.

When the two armies confronted each other, others saw such a large imperial ship, and of course he also saw it. This kind of guilt began to make trouble, he had no burden to kill those 'traitors', and he felt that he had really become a sinner of the Great Song Dynasty when he could directly confront the emperor, and there was no way out. Therefore, he only ordered to strengthen the city defenses, and did not attack while the Song army was halfway through. Of course, he also knew that his little strength was not enough to defeat the Song army.

The next onslaught of the Song army made the troops frightened and retreated. And Liang Xiongfei also knew that the Red Horse Exploration Army was completely annihilated. He abandoned the city and fled without doing anything, and he couldn't explain to the new master, and after a long time, the Song army surrounded the whole city, and he couldn't get out. It was at this time that Zhao Ruogang was going to leave the city and found an excuse for him. In his heart, Zhao Ruogang has a vain surname and a national surname, he has no integrity, he is an out-and-out traitor, and it is only appropriate to detain the basin of Kaecheng on him, anyway, he has done it once.

So Liang Xiongfei opened the city gate in the name of giving Zhao Ruogang a gift. As soon as the gates were opened, they could not be closed, and the defenders of the city thought that the Lord was about to flee, so they scattered in a hurry. Then rush out of the city. Liang Xiongfei was also naturally coerced by the rebels, and the fall of the city had nothing to do with him......

"Your Highness, please enter the city!" Ying Jieyan walked into the cabin and said to His Highness who was crouching in front of the desk and sketching a picture.

"Wait, don't bother me now!" Zhao Yu waved his little fat hand and said.

"Your Highness...... Alas! "It's really a little helpless to be strict. Started to make noise. Even at the expense of taking extraordinary measures against himself, he had to come to watch the battle, but as soon as the battle began, he bombarded the city wall with ballistas for a short time, and he went back into the cabin and never showed his head again, thinking that he was afraid, and threw all this mess to himself, and now the army has entered the city, and the battlefield has been cleared. The armies welcomed him into the city, and he was to lie on the ship. It's really childlike. It made him annoyed and annoyed, laughing and laughing, only a helpless face.

"Sir, don't walk around, keep me quiet!" Ying Jieyan was a little anxious and restless, Zhao Yu raised his head and said with a wry smile, obviously it was a critical moment and he didn't want to be disturbed.

And Zhao Yu's 'avoidance' of the battlefield this time was not as Ying Jieyan thought-he was afraid. Although he is on the battlefield, he is still far away, and now he is not as good as in Quanzhou, there are tens of thousands of soldiers around him, even if the enemy army in the city is killed for a while, he will not be as embarrassed as last time. But there was another reason that made him think of something.

After the ballista began to fire, Zhao Yu paid great attention. The Craftsman Bureau produced a total of more than 80 large and small ballistas this time, and considering that thousands of miles into Qiongzhou mainly relied on the navy, 50 of them were allocated to them. The remaining thirty or so formed a ballista battalion and handed it over to the infantry army. After the battle began, the ballistae attached to the infantry army fired at the same time to suppress the defenders at the head of the city, and Zhao Yu saw that the lethality, destructive power and hit rate could achieve the expected effect, but there was also a serious problem, that is, the rate of fire.

The ballista is a cycle from winding, loading, aiming to launching, and Zhao Hao estimated that the fastest rate of fire could reach about one shot a minute, but it was not easy to do in actual combat. Now, with more than 30 ballistas suppressing the Changsanli front, it is inevitable that there will be intermittent firepower, so that the enemy still has the strength to counterattack, and it is difficult to achieve full-time and gapless suppression. Although everyone is very satisfied with this, it is an intolerable defect for Zhao Hao, a science student who strives for excellence.

After pondering for a while, Zhao Hao thought of a solution: first, to increase the power of the 'cannonballs' to increase the killing surface and destructive power; second, to increase the number of ballistae to make up for the lack of rate of fire; and third, to transform the ballistas, improve efficiency, and improve single shots into bursts.

Subsequently, Zhao Yu optimized the three schemes. To increase the power of the shells under the present conditions is to increase the overall mass of the shells, but the gun carriage also has to be remodeled, increased in size, and reinforced components, but then it also becomes bulky, sacrificing valuable mobility. The best way to simply increase the power of artillery shells is to fill them with gunpowder and turn them into blasting shells, but this is not something that can be achieved in a short time.

Increasing the number seems to be the best solution at the moment, after all, with enough supplies and craftsmen, it only takes a little time to build enough ballistas. But in Zhao Hao's view, this method is not economical, first, it is necessary to train more people and expand the establishment of the army; the second is to waste valuable resources; Third, the usable area of warships is limited, and in order to equip more ballistas, it is necessary to sacrifice the space for loading materials and occupy the places for the crew's activities and rest.

Increasing the firing efficiency of the ballista became the best option, and in Zhao Yu's memory, the craftsmen of ancient Greece did achieve ballista bursts, but later gave up on the ridiculous reason of 'too much waste of ammunition'. Therefore, the repeating ballista disappeared in a flash in the pan, leaving only a few words of legend, but there is no physical object and graphics for reference, later generations have restored this, but Zhao Hao only remembers that a linkage mechanism was installed to realize the ballista cycle winding, automatic drop and realize continuous fire.

Zhao Hao, who had a new idea, immediately lost interest in the fierce battle situation in front of him, turned around and returned to the cabin, spread out the paper and ink, and recorded it in a flash of inspiration. And then his scientific man's nature was exposed, and he devoted himself to design and perfection, and the shouts and drums outside were already deaf, and the victory or defeat of the battle had nothing to do with his own inspiration, and he couldn't struggle out of it until he came to tell him that the battle was over......

There was no dream all night, and when Zhao Yu woke up, it was already three poles in the sun, and he turned over and still didn't want to get up. In the past few days, he has worked hard to plan the town of Qiongzhou, followed by the training of the new army, the formulation of the battle plan and plan for the attack on Guangzhou, and the spirit has been tense until the battle to recover Guangzhou is in full swing, and he has almost exhausted his last trace of energy. And yesterday in order to improve the ballista and labor, the motherboard finally could not support the CPU calculation, and directly crashed, so that he didn't know who carried him to the bed.

"Wang De, Wang De, why is it so noisy outside?" Now that Guangzhou City has been successfully won, thinking that he has successfully taken the first step out of the imperial court, Zhao Hao suddenly felt that the pressure has decreased a lot, and he feels that it is not a sin to sleep a little longer. But his good mood didn't last long, and he was disturbed by the cacophony that came from him.

"Your Highness is awake!" Wang De walked into the cabin quickly, smiled and said to An, "The noise outside is that the people in the city learned that His Highness led the troops to drive away the Tartars, and they came to welcome His Highness into the city." ”

"What?!" Zhao Yu got up with a bone, rushed to the window barefoot and looked out, only to find that the imperial ship had docked at the port last night, and the dock was crowded with people, looking at the imperial ship one by one.

"Where's Lord Ying?" Zhao Yu was shocked, this was not what he wanted, with his original intention to develop quietly, he didn't want to attract the attention of the Mongols too early, so the banners were all played by the imperial court, and the banner of the Shuaifu army was not displayed.

"Your Highness, the city has just been recovered, things are complicated, Lord Ying can't wait, he has entered the city yesterday, and now he is leading the city to meet the king on the dock. Is there anything wrong with that? Wang De saw His Royal Highness's anxious white face, and he didn't know where he had committed a taboo again, which made him unhappy, and replied carefully.

"Alas, the time is not yet ripe to make such a big show!" Zhao Yu's views on 'fame' have not been able to agree with these 'ancients', they want to make a fortune by muffling, and they want to create a momentum, so as to improve their prestige, lay a foundation for future actions, and then consolidate their position. All this is also good intentions, and he can only sigh in vain and enter the rivers and lakes and involuntarily himself.

"Your Highness, what should I do then?" Wang De couldn't figure out the situation for a while, and asked with his head covered.

"Change clothes, line up the guard of honor, and enter the city!" Now that things are like this, I can't do it if I don't want to, Zhao Yu gritted his teeth and said.

It didn't take long, the bells and drums on the royal boat were all famous, a team of warriors took the lead in getting off the boat, lined up in formation, Shaoqing was accompanied by silk and bamboo, wearing a python suit, wearing a crown to the sky, His Royal Highness the King Wei appeared in the bow of the boat, for a time the crowd was passionate, the civil and military people saluted together, chanting His Royal Highness. Zhao Hao crossed the bridge with a smile on his face and got off the boat with the support of the chamberlain, and he frequently bowed his head to the officials and the people, where could he still see that he was still losing his temper just now. only suffered Wang De's angry bag, and there was nowhere to complain about the bitter water in his stomach......
