and Yang Guang Nadao was handed over to Li Hun to bring back to Chang'an, and he was asked to be transferred back to Beijing to continue to preside over the investigation of the case of Guan Zizai, and at the same time presented to Yang Jian, the ancestor of Sui, there was also a piece written by Yang Su, the prince of Qinghe County and the current governor of Xinzhou.

Compared with Yang Guang's recital, Yang Su's recital, which mainly focuses on building a warship and preparing for the defeat of Nanchen and the realization of the great cause of reunification, has attracted Yang Jian's attention.

Since the opening of the emperor in the fifth year of Shi Wansui sword beheading Apo, Datou descended to Sui, the northern border of the Great Sui has been roughly stable, in order to raise troops to the south, in one fell swoop, to achieve the unification of the north and the south to eliminate the trouble.

Not only did Yang Jian himself discover this strategic opportunity in time, but a large number of civil and military ministers in the DPRK and China were keenly aware that the north was decided, and the imperial court would do its best to attack Chen and restore the unity of the north and the south. Therefore, from last year to the present, Yang Jian has received a steady stream of suggestions for the imperial court to raise troops to attack Chen, and there are hundreds of them.

But in these recitals, the vast majority of them are in general advice to the imperial court to attack Chen, at most mention why to attack Chen, rarely talk about how to attack Chen, these recitals have seen too much, even Yang Jian himself has a feeling of boredom, selfishly believes that the vast majority of courtiers do not really realize the necessity and arduousness of attacking Chen, just blindly trying to figure out and cater to the intentions of the people, and everyone is also suggesting to attack Chen.

Only in this way did Yang Su's unique performance arouse Yang Jian's great interest.

Yang Su can be said to be the only beneficiary of the case of Gao De's letter in the five years of the emperor's reign, because he was the first to raise suspicions to the empress that Gao De was instructed by others, and openly wrote a letter to persuade the emperor to abdicate and pass on the crown prince to divide the relationship between Yang Jian's father and son, and was re-appointed by Yang Jian and appointed as the governor of Shinshu.

This time, Yang Su clearly pointed out in the recital that if we want to raise troops to conquer the Yangtze River moat in one fell swoop and realize the reunification of the north and the south, the first thing is to build a strong naval army. Only on the basis that the number and tonnage of warships surpassed that of the Nanchen naval army could we ensure the defeat of Nanchen in one fell swoop and occupy the land on the left side of the river for a long time.

In order to persuade Yang Jian to agree that he would immediately start building a warship, Yang Su also attached a sketch of his elaborate main warship to the end of the chapter, and explained to Yang Jian in detail the weapons equipped with several main warships and the combat power that would be formed when they were put into use.

Other warships (such as Huanglong, etc.) were also dismissed, and the five-toothed giant ships listed at the top of Yang Su's sketch attracted Yang Jian's attention.

According to Yang Su, after years of thinking, he carefully designed the five-tooth giant ship is hundreds of feet high, which is divided into five layers, which can accommodate 800 soldiers, and the weapons equipped with the five-tooth giant ship are eight huge shooting rods in addition to bows and crossbows and light stone machines. Each of the eight poles was dozens of feet long and made of pure stainless steel, and when the two armies were fighting, 50 sergeants swung the rods together to deliver devastating blows directly at the enemy's warships. A warship of the level of Huanglong, as long as it is slapped by the slapstick on the five-tooth giant ship, the ship will be destroyed and killed, and it will suffer a catastrophe.

Although it was difficult for Yang Jian to imagine what the five-tooth giant ship would look like after the completion of construction, a passage in Yang Su's recital made him "suddenly" moved and excited.

Yang Su boasted to the emperor that as long as he was given two years and sufficient funds, when he built eight five-tooth giant ships two years later, he could ensure absolute superiority over Nan Chen's naval army, and it would be as easy as digging for something to conquer Nan Chen in one fell swoop.

Yang Jian has always had reservations about Yang Su's character, but he has never doubted his ability, and Yang Su's recital is the only one he has received so far that starts with military equipment and talks about how to defeat Nan Chen.

Of course, while attaching great importance to Yang Su's performance, the elimination of the traitors and meticulous work that Nan Chen planted in Chang'an and Sui Realm mentioned in Yang Guang's chapter is also very necessary in Yang Jian's view, and even to a certain extent it is a matter that needs to be solved urgently.

With the restoration of stability in the north and the completion of the implementation of the law of the Great Suo Maung Yue and the loss of nationality in the territory, the focus of the imperial court's government affairs is about to shift to the great cause of realizing the reunification of the north and the south.

But the problem was that as early as in the first year of the emperor's reign, before Yang Guang left the town and merged with the state, the envoy who presided over the investigation of Guan Zizi and the "Wild Goose's Nest" was handed over to the crown prince Yang Yong, and it is still the case.

Although Yang Jian was quite dissatisfied with Yang Yong's overly carestaking actions, causing Liu Yi, who might have mastered the important clues of the "Wild Goose's Nest" and Guan Zizai, to die of a violent illness in the prison, and sent him back to Luoyang, the eastern capital, he also summoned him to the Linde Hall alone before Yang Yong left Chang'an, and secretly told him that after returning to the Eastern Capital, he should strengthen the contact with Pei Yun, the general of the Southern Chen Zhige, who was acting as a fine work of the imperial court, and urged him to find more clues about Guan Zizi from the Southern Chen Dynasty as soon as possible, so as to eradicate this scourge as soon as possible.

Over the years, although Yang Yong was not without negligence in presiding over the investigation of the Guan Zizi case, according to Yang Jian, he was still doing his best and there were no major mistakes and omissions, and from Yang Yong's attitude when he responded to the recall to Beijing, Yang Jian found that the prince was very interested in serving as the commander of the war against Chen and personally commanding the army to go south to attack Chen. And he specially sent the prince to the eastern capital under the situation that the overall situation in the north had been determined, and there was indeed a willingness for the prince to personally sit in the town in the future and coordinate the grain for the front.

Therefore, no matter from which point of view, it is extremely inappropriate for Yang Guang to replace Yang Yong to preside over the investigation of Nan Chen's fine case.

Although he has no intention of recalling Yang Guang to investigate the case, he is the first candidate for the commander of Chen in Yang Jian's mind: first of all, he or several princes must be the commander of the whole army to promote the army and attack Chen, which is conducive to establishing the prestige of the Yang family among the government and the opposition, which is beyond doubt;

Secondly, although the crown prince Yang Yong intended to be the commander of the war Chen, he still lacked the actual experience of commanding the army accumulated by Yang Guang in the past few years, and he acted too conservatively (that is, if the Turkic Five Khans allied forces attacked from the northwest in the first year of Kaihuang, if it were not for Yuwenxin's insistence on taking advantage of the opportunity of the main Turkic force to advance westward to lead the army to counterattack, he unexpectedly captured Yunzhou City, cutting off the retreat of the main army of the main army of the map, and the 80,000 Northern Expeditionary Army led by Yang Shuang, the king of Wei, would have been wiped out. At that time, Yang Yong, who was the commander of the whole army, was strongly opposed to Yu Wenxin leading the army to take the initiative to launch a counteroffensive), it seems that it is not suitable to be the commander of the whole army, and other people such as Yang Jun, Yang Xiu and others cannot be compared with Yang Guang in terms of martial arts.

Therefore, Yang Jian thought that it was time to recall his second son from Hebei and order him to start preparing for the attack on Chen.
