Lin Xiangru was suddenly promoted, and was also entrusted with a heavy task, in the face of this arduous task, without fear, immediately took the national book Baoyu, got into the car, entered the Sitong Pass through the iron chain bridge on the Yellow River, and then went straight to the Hangu Pass of the Qin State to ask to see the King of Qin.

In the face of Lin Xiangru going to Qin for help through the four clearances, passing through the four clearances, he met with Han Feizi, the two talked very happily, and after three days and nights, Han Feizi sent Lin Xiangru out of the customs to Qin.

The reason for this is that the current 4 customs clearance is the world's free port, the hub of commerce. According to Zhao Xing's rules at the beginning, no matter who it is, no matter what kind of responsibility this person shoulders, as long as he does not harm the four clearances, you will be allowed to come and go.

This is also the reason why 4 clearance, sandwiched among many princes, and the blood-red eyes of each prince fighting, but they are also safe and sound.

Because all the vassal states know that the four customs clearances are the throat of their own countries to export surplus products, and at the same time, they are also the channels to obtain materials that their own countries do not have, and at the same time, they are also the way to obtain the four customs clearance loans when the economy is tight.

Although everyone knows that the money lent is Zhao Xing's, the principle of his lending is that no matter whether he is friend or foe, as long as there is enough collateral, even if the enemy who is fighting a life-and-death battle needs military salaries and takes out a loan, he will still take out the loan.

So everyone knows that the four clearances are fat, but everyone doesn't dare to eat them, and they have to go all out to protect whoever dares to move the four clearances, they will immediately become the public enemy of the world.

Lin Xiangru easily passed the four clearances and came to Qin's Hangu Pass, and entered Xianyang to meet the King of Qin.

This generation of King Qin is King Qin Zhaoxiang is the Empress Dowager Xuan and Zhao Yan together, and at this point, there is still some incense with Zhao State.

At the same time, Qin had already occupied Han's Yiyang, cut off Han's Shangdang, and prepared the conditions for Qin to occupy the important place of Shangdang.

Shangdang has the meaning of the same party with the sky, it is the highest point of the northwest terrain, Taihang Bashan, Shangdang controlled five, the Qin army went out of the Fukou Peak until Handan, the political center of Zhao State, even if the war was unfavorable, it could also retreat into the Taihang Mountain, use the mountains to resist step by step, wear down the organization of the Zhao army, and wait for reinforcements. Crossing the Yellow River out of Taihang can threaten Daliang, the capital of Wei, and Xinzheng, the capital of South Korea, as long as the Qin army has a firm foothold in Shangdang, it can be based on the Changzhi, the center of the party, and carry out a high-level attack on the Hebei Plain and the Heluo metropolitan belt at any time. From then on, the capital of the Three Jin Dynasty no longer had any barriers, and the iron cavalry of the Qin army reappeared under their capital overnight.

At the same time, Qin occupied Shangdang, and Jiuyuan, an important industrial center in the north of the Tang Dynasty, divided the territory of the Tang Dynasty into two, so that Zhao Xing could not care about each other.

For this reason, Qin Zhaoxiang Wang Yingji and Chu Huai Wang Xionghuai formed an alliance in Huangthorn. At the same time, the state of Qin returned Shangyong to the state of Chu. In order to ensure that when Qin captured Shangdang, the state of Chu would not involve its hind legs in the south. He was going to return the captured land of Korea to Korea and use it in exchange for the party.

However, although South Korea knew that Shangdang had become an enclave, it firmly disagreed for strategic reasons, and Qin Zheng was preparing to oppress and encroach in order to achieve his goal.

Of course, at this time, South Korea can be so insistent because of Zhao's support. In the end, Qin achieved his goal, and it was only twenty years later that South Korea had to learn from the original British one daughter and two marriages, and the general Xu Qin Zhao was sent to the party, which triggered Qin Zhao's Changping War.

However, this history is no longer the complexity of the original history, because the emergence of the Tang Dynasty has changed the original history and become simpler.

Now, the great enemy of the world is no longer Zhao, Qin, Qi, and Chu, and the battle is unclear, Datang has actually become a clear goal of unifying the world, and Datang suddenly sent troops to occupy Zhao, and everyone also understands that the steps of Datang to unify the world have begun.

The princes of the world have begun to unify the world for themselves, or they have begun to plan for self-preservation.

For example, the new monarch of South Korea, the original Prince Cang, after Zhao Xing occupied half of Zhao State, he felt threatened, don't take Zhao Xing as South Korea's niece and son-in-law seriously, in this era, the most unreliable thing is family affection. Therefore, under the leadership of Gongsun Hao, he carried out the strategy of bringing trouble to the north, and took the initiative to send envoys to cede the Shangdang to Qin, in exchange for the four hundred miles of land occupied by the Northern Qin, and strengthen himself At the same time, he hoped that Qin could send troops to the Tang Dynasty based on the Shangdang to relieve the pressure on Zhao, so that Zhao could block the footsteps of the Tang Dynasty in the south for Korea.

When Lin Xiangru came, Qin and Han basically achieved their goal, and Lin Xiangru didn't know about it.

Lin Xiangru met with the King of Qin and explained his intentions, the King of Qin already had a bottom in his heart, of course, he was unwilling to follow the will of Zhao State, ask the Qin army to send troops to Hetao, and copy the back road of the Tang State, it was a hard-fought war. Hard to beat, Qin Guo did it with Zhao Xing when he was King Wu, and the head was broken and bloody, and the 200,000 old Qin army died 120,000 in a battle, think about it, now the brain is still buzzing. Now for Zhao Guohuo? Silly. It's better to occupy the party and come out at any time.

Occupy the Shangdang, take advantage of the fact that Zhao State was beaten by Zhao Xing and it was difficult to parry, fall into the well, and send troops from Shangdang to Fukou and Bingfeng to Handan, the political center of Zhao State, and take the opportunity to make a profit.

Even if Zhao Xing doesn't let go, everyone can retreat to the party again, rely on Taihang Mountain, block Zhao Xing's attack, and make everything that can be attacked, retreated, and defended. Then suddenly the troops went out of Jiuyuan, smashed Zhao Xing's industrial base, smashed his armed production base, and smashed Zhao Xing's money bag to raise soldiers.

King Qin played with He's Bi in the palace, this is indeed the world's treasure, he really can't put it down, and he passed it to the concubines and attendants, and the ministers cheered "Long live".

Lin Xiangru saw that the king of Qin did not send troops to attack Tang and help Zhao Guo, so he stepped forward and said, "There is something wrong with Bi, please let me show it to the king." ”

The King of Qin handed over He's Bi to Lin Xiangru. So, Lin Xiangru took a few steps back and stood still, leaning his back against the pillar, and his angry hair stood up. He said to the king of Qin, "If the king wants to get He's Bi, he must announce to the world that he will attack Tang's Hetao, and if he doesn't send troops, he will get this world's treasure, and my head will be smashed on the pillar with He's Bi now!"

The king of Qin was afraid that he would smash He's Bi, so he apologized politely, resolutely begged him not to smash He's Bi, and promised to attack the Tang Dynasty.

Lin Xiangru estimated that the king of Qin was just talking, and there was no sincerity at all, so he proposed again, "He's bi is a treasure recognized by the world, and now the king should also fast for five days, and set up the etiquette of "nine bins" in the court, so I dare to offer He's bi." ”

The king of Qin estimated that this situation could not be forcibly seized after all, so he agreed to fast for five days and placed Lin Xiangru in the Guangcheng Hotel. Lin Xiangru estimated that although the king of Qin had promised to fast, he would definitely break the covenant, so he sent his retinue, dressed in coarse cloth clothes and carrying the piece of bi, to escape from the trail and send it back to the capital of Zhao.

staged a play to return to Zhao, and in the end, Qin did not send troops to the Tang Hetao, and Zhao did not send He's Bi, staging a farce.
