After listening to Zhang Yi's explanation, Wei Si still had some doubts:

"Zhang Yi, are you really for my Great Wei?"

Zhang Yi raised her hand and swore:

"I, Zhang Yi, dare to swear, since you succeeded to the throne, although I, Zhang Yi, am the prime minister of Qin, everything I do is to help you, the king, and to achieve the unification of the Great Wei!"

Chen Zhen and Ruer were silent at this time.

Wei Si asked:

"Since you are for the unification of Great Wei, how do you think our Wei State can quickly achieve the unification of the world now?"

Zhang Yi replied:

"If my Great Wei really wants to be unified, it will take at least twenty years, five years of cultivation and recuperation, accumulation of strength, and another fifteen years to conquer the world and seek unification!"

Wei Si couldn't help asking:

"Then according to you, sir, what is the current situation?"

Zhang Yi replied:

"If today's trend is like today, Wei and Qi are the only strong, Chu, Qin, Zhao, and Han are second, Yan and Yue are again, and Song, Zhongshan, Zhouzhou, and Lu are the weakest!"

In fact, Zhang Yi came here today, it was just a play played by Wei Si and him, for Chen Zhen, Ru Er and others to see, after the alliance with Han Wang Michi, although Wei Si did not meet Zhang Yi in person, but he had secretly talked with Zhang Yi in private.

Otherwise, Zhang Yi would not have been plotting for Wei, and did something that was really Qin Xiang, called Wei Chen, and Wei Hei did not stand up for a long time after Gongsun Yan left, in fact, it was also for Zhang Yi to stay.

At this time, Wei Si signaled all the others to retreat, leaving only Chen Zhen, Su Dai, Ru Er and Su Qin, and then asked Zhang Yi:

"Okay, then according to your wishes, sir, the widow will determine the world in the future, in what way?"

Zhang Yi replied:

"First of all, our Wei State can have the friendship between you and Yan State, the king, and the Yan State will be closely united, so that Yan State can send troops to threaten Qi State, forcing Qi State to be unable to aid Song, our Wei State took this opportunity to destroy Song State, and give me the benefit of Wei State to recuperate with the richness of Song Land!"

Wei Si asked again:

"And then?"

Zhang Yi continued:

"After the destruction of the Song Dynasty, our Wei State needs to unite with Korea and Zhao to force the King of Qin into Bashu, and then unite with Korea to continue to weaken the Chu State, and then turn to the contradictions of the above party and provoke Zhao and Han to fight, so that our Wei can destroy Lu first to the east, and fight Qi together with Yan and Yue, so that the countries will be weakened day by day, and our Wei State will be even stronger, until the countries are destroyed one by one."

Chen Zhen said at this time:

"Zhang Yi, your plan is really good, but I'm afraid it can't be done in twenty years, right?"

Zhang Yi replied:

"I'm only talking about the least, so if something happens, it's going to be longer!"

Wei Si also said:

"Isn't there a better way? And with the current situation, South Korea may become strong again! ”

Zhang Yi smiled:

"The king doesn't have to worry about South Korea at all, although Xinzheng is close to my Daliang, but South Korea has already lost its Hebei and Shangdang land, it is like losing an arm, and it is already surrounded by our Great Wei, so as long as the king is stationed in Xiuyu, South Korea will not have the idea of acting rashly, because our Xiuyu army can defend Daliang, and can go to Xinzheng City in one day without bloodshed, unless South Korea moves its capital, otherwise it will never dare to betray our Great Wei again."

Wei Si asked again:

"Then what if Korea unites with Chu or Zhao in the future?"

Zhang Yi replied:

"Isn't that what you want, my lord? The king, you can just send troops to destroy South Korea, now our Wei State has occupied so much land, and as long as the Song State is destroyed, the closest country to our Great Liang in the future will be in addition to South Korea, that is, Zhao State, but now our Wei State has garrisoned in Zhongmu, if Zhao State moves, it must attack Zhongmu first, otherwise its capital Handan has always been under the threat of our Zhongmu army, taking advantage of the time when Zhao State attacked Zhongmu, can't our Wei State capture a Xinzheng? ”

Wei Si nodded his forehead:

"Sir, what you said is still right, the widow will continue to increase troops in Xiuyu in the future, and then pull South Korea to attack other countries, if South Korea has different intentions, the widow will order the army to go straight to Xinzheng to destroy Han."

Su Qin said at this time:

"We shouldn't discuss these now, now our Great Wei is in the midst of a confrontation with Chu, and we can't get out, and the west may face the threat of Qin!"

Zhang Yi smiled:

"So I, Zhang Yi, is going to the Qin State to help the king and solve the possible threat of the Qin State this time!"

Su Qin asked Zhang Yi:

"I don't know what you plan to do to persuade the King of Qin after you go to the Qin Kingdom, sir?"

Zhang Yi replied:

"The King of Qin is old, and after the Xianyang was broken, I am afraid that his body has become even worse, so I will go to the Qin Queen this time, and I will persuade the King of Qin to put his body first, and give his prince the power to win the disease, so that Yingdang is the main general and preside over the affairs of the Chu Dynasty, which will be of great benefit to my Wei State!"

陈轸 says:

"But we sent an envoy to Qin this time to ask the king of Qin for the grain and grass of Bashu and the Wei Jun who fled from Qin, Zhang Yi, but you went to persuade the prince of Qin to preside over state affairs, this is a bit irrelevant, right?"

Zhang Yi replied:

"Chen Zhen, at this time, the Qin State has already moved to attack my Wei State, if our Wei State sends an envoy to Qin to ask for grain and grass and Weijun? Is the Qin Congress willing? This will only force the Qin State to sneak attack our Great Wei again, not to mention that our Great Wei is now facing off with the Chu State in the south, and there is no defense against the Qin State in the west. How can you do this by shooting yourself in the foot? ”

Wei Si said:

"Also, if you don't mention it, the widow is really going to do foolish things again, but after this Qin prince is in charge, what will be of great benefit to my Wei country?"

Zhang Yi replied:

As long as the King of Qin gives him the right to fight, he will definitely not be like the old fox like the King of Qin, saying one thing and doing another, he will definitely order the Qin army to attack Chu with all his might, and will not come to attack our Great Wei, because our Great Wei has just assisted the Qin State not long ago, and the King of Qin is mean and unkind, but his prince Yingdang will not do such a thing."

Wei Si had some doubts:

"But how can you convince King Qin to give power to the crown prince, will King Qin still believe you Zhang Yi?"

Zhang Yi replied:

"King, don't worry, I, Zhang Yi, have served the King of Qin for so many years, what kind of person is the King of Qin, I Zhang Yi knows best in my heart, his suspicion is very serious, and he likes to do everything the other way around, otherwise I, Zhang Yi, will not return to Qin in the name of the Wei envoy this time!"

Wei Si then said:

"Okay, then this time we Wei can count on you, sir, as long as you make Qin State go all out to attack Chu and solve the difficulty of the confrontation between Wei, Han and Chu, then you come back to serve as prime minister, presumably no one in our Wei State will have any objections!"

Zhang Yi made Qin in the name of Wei Chen, and after arriving in Qin, he repeatedly told the king of Qin that the prince who had always hated him was good at winning, so he won the trust of the king of Qin again.

The king of Qin also listened to Zhang Yi's persuasion, and on the grounds that he was old and sick, he was relieved of his position as the main general, and he temporarily retreated to the background, and ordered the crown prince to preside over state affairs on his behalf.

Yingdang really canceled the old Qin King Yingsi and Zhu Liji's original attack on Wei, and appointed himself as the commander, personally leading the Qin army that had been withdrawn from Danyang, and attacked Chu again.

The state of Chu suffered from the enemy, and the king of Chu had no choice but to make peace with Han and Wei, demarcate the boundary with the water, and recognized the Chu land occupied by Wei and Han.

The Chu army and the Qin army fought at the city of Yancheng north of Yingdu, and the two armies fought for three months, ending the battle with the king of Chu taking the initiative to make peace and recognizing Danyang as Qin's land.

After the Wei army withdrew from the water, it did not stop, and the ice front went east, and immediately attacked the Song State, and the Song State asked the Qi State for help, and the Qi State was retaliated by the Yan State in the north at this time, and the South Gate was attacked by the Yue State, and was unable to aid the Song State.

Therefore, while Qin and Chu were in the truce in Yancheng, the Wei soldiers did not fight bloodlessly and took Suiyang and all the Song lands of the Song State.

Wei Si also interrogated Song Jun who was escorted in the main hall of Wei Palace:

"Song Yan, as a Chengtang and Weizi, you manage countless Yin Shang people, but you are mediocre and desolate, causing your Yin Shang people to grit their teeth at you, and they can't wait to say that you are divided into five horses, this king is the son of heaven, conforms to the will of the people, and crusades against you, what else do you have to say now?"

Song Junyan also knew that he had reached the end of the world, and his face was pale with fright:

"The king, the king, I, Song Yan, am indeed guilty and guilty, as long as the king spares my life, I will definitely persuade all the Song people to surrender to the Great Wei and the king for generations in the future!"

Wei Si shouted:

"The widow was supposed to comply with the will of the people and split your five horses outside Suiyang City, but considering that you were a sage and became a soup, he didn't want to cut off the sacrifice of the soup, so the widow decided to move you to the capital of your ancestors to sing as a sacrifice, can you obey?"

Song Junyan hurriedly knelt on the ground and thanked him:

"Thank you to the king, thank you to the king, I, Song Yan, swear that in the future, I will sacrifice to the ancestor of Chengtang and serve the king!"

Wei Si said again:

"I hope you can strictly abide by your ancestral business in the future, and don't let the widow down like Wei Jun, you know?"

Song Jun kowtowed again to thank him:

"Song Yan, I will never be a rebellious minister like Wei Jun in the future, and I will only serve the king and serve my Great Wei loyally for the rest of my life."

So Wei Si destroyed the Song Dynasty, which had just been established for more than 800 years, moved the Song Dynasty to Chaoge, and offered sacrifices to the Song Dynasty to appease the Yin people of the Song Dynasty, and sent thousands of troops to monitor Chaoge.

In the spring of 111 B.C., the hometown of the Song State suffered a flood, the corpses were everywhere, the treasury lacked food, and could not cope with the disaster.

Prince Qin Yingdang originally wanted to send grain and grass to Wei, but was intercepted by King Yingsi, who had recovered a lot, and King Qin came out to govern again.

The king of Qin refused to intercede with Wei on the grounds that Qin was in ruins and had no grain to borrow, and Wei was angry, and sent Sima You to Qin to ask Qin for Weijun.

The king of Qin not only refused again, but in front of the Wei envoy Sima You, he invited Wei Jun to a banquet in the Yongcheng Palace, so that Wei Jun humiliated Sima You, Wei Si couldn't bear it, so he united with Korea, and the two countries gathered troops and horses in Yin and Jin and began to crusade against Qin.
