There is no doubt that if the position of the prince of Beiyan is bound to fall to another family; So just on paper, only the four princes are up to the task.

For such a thing as succession to the throne, it is possible, but there is a threat; And compared with military merits, the prince is far from being Zhou Changan's opponent; Compared with the prestige and reputation of the military and civilians, he can't catch up with his half-brother. Before the start of the Huayu War, there were also lackeys under the Cai Party and the Prince's Mansion above the court, who could press Wang Fang and Zhou Chang'an, a pair of masters and apprentices; But recently, under the pressure of huge pressure, the prince has been full of loopholes, misjudged the current situation and holy will, and rashly launched an offensive to reverse Cai......

Not to mention how the people in the Cai Party will counter the treacherous prince; Cai Ning, the eldest son of the Cai family, is still fighting on the front line! In public and private, Emperor God will inevitably give the Cai family father and son, a very satisfactory explanation!

In fact, even if Cai Ning had no soldiers and no power, it would be impossible for Emperor Tianyou to pull out the chess pieces he had stepped on. And the crown prince was also pushed to the edge of the cliff by his self-inflicted cleverness. The liquidation and revenge of the people in the old party, Wang Fang and Zhou Chang'an's "beating the side drum and beating the gong", are not the huge pressure that the prince, who is already alone, can withstand!

Zhou Changyong completely collapsed at this time and became a "madman", and his intentions were simply revealed!

Everyone knows that as long as Emperor Tianyou has no intention of abdicating for a day, the prince's madness will not be good for a day; And the civil and military officials are looking at the face of Emperor Tianyou, who is embarrassed to liquidate a "crazy prince"?

So whether it is Cai Dagongzi or the old party, they have never even mentioned this matter again! Because His Majesty and Wang Fang came forward to testify, it has been proved that the prince committed this mistake and the two of them jointly carried it! Of course, this matter cannot be erased alive; When the world is calm, the two sides will negotiate on the "price"!

The three families have been attacking and compromising each other for many years, and they have enough tacit understanding that there is no need for additional communication.

And this tacit understanding is called the "rules of the game".

Right now, Pang Qingshan's army is pressing the border and is about to launch the final offensive. No matter how the war develops and ends, Zhou Yuanqing, as the king of a country, cannot be brave for a while. Since the Zijin Palace will definitely not be able to go back, Emperor Tianyou wants to take advantage of this opportunity to simply make his words clear, so as not to make a mistake again in the future and leave a fatal flaw for the fourth prince Zhou Chang'an, who is becoming more and more full-fledged and has a hundred battles......

After a simple exchange between the husband and wife, Empress Zhang trembled and withdrew from the stone room; And Zhou Yuanqing slowly stepped forward and sat on the side of the bed of the crown prince Zhou Changyong......

Bang!

Just as he was thinking about how to start, a loud noise came from the top of his head into the stone room, and the teacups on the stone table also rippled endlessly......

There is no doubt that the trebuchets and Thunderbolt chariots of the Relief Army have just undergone their first test firing; Ten round boulders the size of a grinding plate, and ten thunderbolt fire bombs wrapped in flames, drew a high parabola, leaped over the towering Yanjing city wall, and fell into the capital of the Northern Yan Dynasty......

In addition to the Nankang Dynasty, which called itself the "light of Huayu", the siege equipment of Huayu is still traditional and outdated: the trebuchet has no accurate head at all, and the landing point is completely unpredictable; The ladder is also a bamboo tube sleeve bamboo tube, and an iron hook is thrown out at the top to climb the city wall. As for the simple suspension bridge, it is even more ridiculous, it is just a downed bamboo ladder with a layer of inferior animal skins on it......

On this way, you have to go through a series of eating and taking cards, geese and plucking...... In addition, improper storage and poor craftsmanship do not require much of a role to be played on the battlefield.

However, considering that Yanjing City is a new capital, it has only been built for a hundred years; With its far beyond the standard of fortifications and city defense weapons, it can indeed be called impregnable, and it is difficult for immortals to cross. It's just that this degree of solidity is based on the siege equipment of a hundred years ago as an imaginary enemy; And the power of the siege equipment in the hands of the Nankang army, I am afraid that even they themselves do not understand.

Pang Qingshan's first test launch was very small; But on the question of "shield strength or spear sharpness", there has been a clear and straightforward result. For the new ordnance of the Tianji Workshop, the originally wide moat has also become a road to heaven; The originally towering city walls and safely selected watchtowers are also in front of the high parabola, fragile as if they have been weathered by years of window paper......

It can be seen from this that it is indeed very wise for the veteran Wang to release his armor and enter the court, and no longer participate in tactical guidance and overall coordination. And the reason why he dared to stand on the top of the city today to watch the enemy plundering the formation was precisely because he held the stereotyped thinking that Yanjing City's defense was impregnable and the fortifications were unbreakable......

After a round of test firing, the Worry Relief Army turned Wang Fang's battlefield experience accumulated over the years into a naïve joke.

After the first round of test firing of the enemy began, six of the ten stone projectiles hit the target, destroying five arrow towers and watchtowers in the urn city! The remaining four, one of which had a slightly lower arc, struck the wall on the left side of the gate, leaving a shallow pit mark that was recognizable to the naked eye; The other three had a huge mistake in the throwing angle, and finally fell into the moat, stirring up a "stormy wave"...

As for those lighter Thunder God Fire Bombs, they successfully crossed the two walls of the Urn City and the Outer City and fell into the inner city of Yanjing. As for how many fires can be caused, for Pang Qingshan, it doesn't matter at all!

Pang Qingshan was overjoyed, and Wang Fang's face was pale! The gold-swallowing beast of the Tianji Workshop finally showed its hurtful fangs! The first round of test firing of the Worry Relief Army, the hit rate is simply scary! If the siege equipment produced by the Tianji Workshop can reach this level in terms of power and effect! Then this decisive battle, in fact, does not have to fight at all!

If Wang Fang stood in Pang Qingshan's position, he would not even need to install simple suspension bridges and ladders, and even a pioneer soldier would not be sent forward; With the assistance of such a battlefield killer, how many trebuchets and thunderbolt chariots are at hand, all lined up, and all the hard objects are thrown into the city in one go!

With those antique-level collectibles of the Northern Yan Army, there is no way at all except to stare and be beaten!

Moreover, in terms of the financial reserves of the Nankang Dynasty and the exclusive technology mastered, it would not take much effort to rebuild this "Youyan City" after the war; As for the intangible assets of the Son of Heaven's dormitory, national treasures and other cultural and historical materials, they are all staying in Chang'an City now!

It can be said that looking at the entire Yanjing City, except for the head of Emperor Tianyou, there is no temptation for the Nankang Imperial Court! If it is destroyed, it will be destroyed, and if it is smashed, it will be smashed, there is no pity.

For the Relief Army, the first round of test firing was to adjust the projectile angle of the siege equipment; Twenty samples, sixteen hits, this result is far beyond the normal level.

Pang Qingshan, who was full of ambition, looked at Wang Fang, a veteran who had just been dragged down the city tower by a few personal soldiers, and added a little certainty of victory: In this way, this group of poor ghosts and buns of the Northern Yan Dynasty really haven't seen any big scenes! After only one round of test firing, the backbone of the enemy army was knocked out of the city and fled for his life! What's more, the brainchild of the Tianji Workshop has not yet appeared!

After the first round of test firing, Pang Qingshan nodded to the standard-bearer beside him. After a burst of flags, twenty auxiliary soldiers of the Liberation Army pushed an old-fashioned ballista to the other side of the south gate and conducted a separate test firing; And the rest of the worry relief army was also busy, and the southern battlefield of Yanjing City once again entered the tranquility before the storm......

The army of anxiety has a bottom in their hearts, and they are debugging the siege equipment step by step; But Yanjing City, which was attacked by test shooting, has fallen into a huge chaos!

In fact, in terms of the results alone, Pang Qingshan's identification of the Beiyan military and civilians as "soil buns" is not a wronged one. Whether it is the battle-hardened old fox Wang Fang, or the Luo couple who are full of poetry and books and have hills and ravines in their chests, including the old and young masters of Yanjing City, they all overestimate the reliability of Yanjing City's defense in their hearts. In the eyes of the Northern Yan people, who claim to be the orthodox Huayu and the lord of the Central Plains, there is no siege equipment in this world that can pose a substantial threat to Yanjing City.

And this view is also supported by empirical evidence. The siege equipment restructured by the Tianji Workshop is not a secret weapon that has never been revealed. The fourth prince, Zhou Chang'an, encountered this kind of Nankang weapon in Hedong City; And Wan Changning, the prime minister of Youbei Third Road, has already sent the preliminary research results of Mobei siege equipment.

According to past combat examples and measured data, the siege equipment produced by the Heavenly Machine Workshop these days, whether it is the shooting range or the range, cannot bring any threat to Yanjing City!

However, whether it is Youbei or Beiyan, they only know one and do not know the other. In order to "instigate the stupid dog to jump over the wall", the Nankang Dynasty did "give" a large number of siege equipment for the Qin Wangfu and the Shenshi tribe to equip. It's just that the Nankang Imperial Court is using some updated old styles to try to exchange for future benefits......

If an old weapon is placed in a warehouse, it will inevitably turn into a pile of rotten wood, so why not let it be used to its spare time?

The Northern Yan people intended to go deep into the enemy, and of course they also began to prepare for war in advance; But the most important energy was put on the two aspects of food, grass and ordnance; As for the ordnance to defend the city, it is the most common material for defending the city, such as strong bows and crossbows, feather arrows, fire oil, swords, shields, spears, rolling logs, stones, etc.; Compared with the advanced products of Tianji Workshop, it is not on the same level at all!

Now that a test launch of the Nankang Army has been completed, the losses caused are not small, but they are not unacceptable. The arrow towers and watchtowers destroyed by stone bullets were set up inside and outside the urn city; Since the location distribution is extremely reasonable, there is no collateral loss; As for the dozens of longbowmen buried in the rubble, it is indeed a sigh of relief; But the damage caused by the trebuchet is nothing compared to the fireball thrown by the Thunderbolt chariot!
