Under the rule of Shang Ying, the Qin state became increasingly powerful, especially the reform of the military meritorious, which greatly improved the combat effectiveness of the Qin army, making it quickly become an invincible force.

If the Qin army wants to send a letter to Guguan to compete for hegemony in the world, the first obstacle to be removed is the Wei State. Wei was once the most powerful of the three Jin dynasties, and at one time forced Qin to cede land and sue for peace. However, the king of Wei was arrogant and domineering, made enemies everywhere, fought for many years, and the national strength was exhausted. As a result, under the offensive of the Qin army, there was no power to parry, and several cities were lost, Shang Ying led the Qin army to soon come to the city of Daliang, and Han and Zhao were so powerful that they did not dare to send troops to rescue.

The battle situation on the Wei side made Chen Xiang restless, but he was really powerless, because once the slippery state sent troops to save Wei, the Qi state, as an ally of the Qin state, would raise troops to attack, and then it would inevitably fall into a two-sided battle, and the consequences would be unimaginable. All Chen Xiang can do now is to send people to lobby the kings of Han and Zhao, hoping that they can understand the truth of cold lips and teeth; On the other hand, he continued to secretly send materials to Daliang City, hoping that Wei would be able to endure the changes.

On that day, in the main hall of the Slippery Palace, the ministers were silent, and Chen Xiang frowned and was at a loss. Suddenly, someone from the palace came to report, and the envoy of the Yan State, Le Yi, asked to see him outside the palace. Chen Xiang was overjoyed when he heard the report, and immediately cheered up and prepared to meet the envoys.

Outside the main hall, I saw a man in white stepping over, heroic and imposing. When Le Yi came to the palace, he saluted and said, "Le Yi, the envoy of the Yan Kingdom, pays a visit to the king." Chen Xiang replied with a smile: "The envoy has worked hard, there is no need to be polite, please hurry up." Le Yi thanked Chen Xiang, stepped forward to hand over the letter of state, and returned to the palace to say: "My Yan country has been oppressed by the strong Qi for a long time, and I occupy my land and my people for no reason. Now I heard that the king returned to the north, turned the tide, and wanted to benefit the people in my north, so he came to ask the king to preside over justice. Le Yi said goodbye.

Chen Xiang walked down the hall, took Le Yi's hand, and said cordially: "The king of Qi has heard of it, and this king also expresses deep sympathy for what happened to Yan Guo. Le Yi thanked him, Chen Xiang hurriedly helped him up, and continued: "However, the matter of Vaqi is very complicated, and the details of all things still need to be discussed in detail with the king for a few days." Le Yi readily agreed.

Chen Xiang arranged Le Yi in a courtyard near his dormitory, during which Chen Xiang went to the courtyard every day, and Le Yi was inseparable. The two talked about everything from national affairs to personal life, chatted happily, and had the intention of seeing each other late.

The plan of the slippery swallow joint attack on Qi was quickly set, first by the slippery army to open the formation of all-out attack, to attract the main force of the Qi army to gather on the border of the slippery Qi, and wait for the arrival of the Qi army, the slippery army and the battle and retreat, the Qi army into the territory of the slippery country and then send troops to harass, so that it is in a dilemma, and can not withdraw, the Yan country can take the opportunity to attack the Qi country with all its strength, the Qi country must be unable to parry, at this time the slippery Qi army will inevitably be in turmoil, and return east in a hurry.

Of course, many details during this period, Chen Xiang and Le Yi had already discussed in detail, and Le Yi returned to Yanguo to report.

On the day Le Yi returned to China, Chen Xiang prepared wine to send him off, and the two said goodbye, just looking forward to seeing each other in the future. Along the way, Chen Xiang sent each other off, and couldn't bear to turn back, Le Yi kept thanking him, and asked him back again and again.

Le Yi has been with Chen Xiang since these days, he has already introduced Chen Xiang as a confidant in his heart, he never thought that a monarch could be so courteous to his subordinates, these days he never felt that he was discussing state affairs with a monarch, but like gossiping with a friend for many years. At this time, an inexplicable thought arose in Le Yi's heart: It would be nice if he met Chen Xiang first.
