Xiang Yan's judgment was not wrong, Qin Guo did it. And it's done very quickly.

The Qin Navy then issued an order to recruit all armed merchant ships as reserve ships of the Qin Navy, and these ships were to receive the training program issued by the Qin Navy except for commercial purposes. If you go out of the river, you need a large number of armed merchant ships in a unified formation. Then go to sea, and at the same time, the Qin Navy temporarily built some special supply ships for special supply in order to solve the problem of Qin ship supply difficulties.

In order to strengthen the vigilance, the Qin State made two important measures, the first was that the special marine corps began to board the ship for combat. These marines, in squads, entered the ships for alert. They are well equipped. The second measure was to redesign and build Qin's armed merchant ships and some specialized warships.

Taking into account the problem of the weakening of the close defense of the ship after the ship is large. The Qin people came up with some solutions of their own. The first is to speed up and rely on the speed of sailing to get rid of the close. This can indeed be done, because the ships of the Chu State are manpower and sails, and they are far inferior to the ships of the Qin State in terms of speed, and the second idea is to seal the ships. The entire ship was redesigned with sealed hatches, which used the force of gears to close the hatches from the inside to improve defense. Fire extinguishing facilities are installed, and at the same time, in order to improve the ship's susceptibility to fire. Coal-fired, fuel specially designed for storage in the cabin. At the same time, some weapon systems have also been sealed and welded using fully enclosed steel plates. This also meant that all the ships of the Qin State no longer used some of the wood. Instead, it is treated entirely with steel.

However, the ships of the Qin State during this period were still flat-bottomed boats suitable for navigating the freshwater rivers of the Yangtze River. Such ships are not very suitable for sea navigation. But what the Qin State needs at the moment is this kind of ship. It takes a while for the ocean to have a clear strategic goal.

The Qin Navy will take a while, and this time has already put some pressure on the Qin Navy. But at the time of the development of the Qin navy. A person has encountered walls everywhere in the Qin State, and this person is the envoy of the Yan State.

The state of Qin already knew what was happening on the Eastern Front. And he also knows what will happen next in Yan Kingdom. The Qi army has preliminarily completed the encirclement, and the 150,000-strong army has surrounded the Yan army in five places, with about 40,000 Yan troops. It was only a matter of time before the Yan army failed.

When King Yan got such news, he was at a loss. He didn't know what to do. If you had known to retreat, you could have avoided such a situation. You should listen to the Qin State. But now it's too late.

In the end, King Yan pinned his last hope entirely on the Qin State, and he hoped that the Qin State would help the Yan State achieve a miracle, so he sent reports to Ji Xin one after another to find someone who could help the Yan State in the Qin State. And told him that the final bottom line of the Yan Kingdom is their national border, and if the national border is crossed, everything will be difficult.

After receiving such an order, Ju Xin immediately came to Shang Wen, who hoped that Shang Wen could provide some help.

"I said a long time ago that we should listen to the words of those military experts, if the Yan army retreats as soon as possible, perhaps, we will not face such a situation." Shang Wen said in a tone of lesson.

"Yes, yes, yes." Ji Xin nodded yes.

"So, is the Qin State giving us some assistance to the Yan State so that we can stabilize near the national border." Ju Xin stated the purpose of the trip.

"This, I'm afraid it's a bit troublesome. You must know that the situation in the Qin State is not very good now. As for military supplies? We'll figure it out. Shang Wen said.

In fact, Shangwen has no choice. The Qin military can't come up with any good solutions, the key is that the Yan State has no strength to use.

"Yan Guo doesn't have any reserve forces to use, what can we do?" Wang Jian looked at the huge sand table and said.

And the staff officers around him felt the same way. The Qi army has a strong new force. And the Yan Kingdom, except for the army that has been left for too long and has lost its combat effectiveness, I am afraid that there is no army that can be used.

"So will we send troops?" A staff officer asked.

"Sending troops? Yes. Absolutely. Wang Jian looked at the staff officer and said.

"The heavenly will come out, the earth, impossible. Who are the people of Yan Guo, are they our mother-in-law? No, it's nothing, so it's enough to dispatch the Celestial Army. Wang Jian said.

Shang Wen's thoughts were the same as Wang Qian's, and he also believed that there was no need for Qin to send troops, especially the intervention of ground forces, and the intervention of air power only lost a few planes and so on. But if the ground is invested, then that cost is quite large.

But if the ground forces are not invested, then the battlefield war will be unfavorable to the Yan State, and the Qin people can't think of any good way to solve this problem at present. And Ju Xin has to go to Shangwen every day.

"The envoy of the Yan Kingdom is here." The assistant asked.

"Nope." Shang Wen replied directly.

"Understood." The assistant said.

"Special Envoy, our Prime Minister is out and needs to inspect some places. You know, Qin is so busy. The assistant said.

"Oh. I understand. Got it. Ji Xin said.

The next day.

"Our prime minister has gone to Xianyang Palace." The assistant said. Ji Xin smiled helplessly. He sensed that the people of the Qin State were deliberately avoiding him.

The same was true on the third day, but for the same reason yesterday. This made Ji Xin feel a little unbearable.

Just when the envoys of the Yan Kingdom came to Shang Wen one after another. The General Staff of the Qin State finally came up with a set of plans. That is, the use of mercenaries and the use of mercenaries to help the Yan people fight. But it's a defensive war. Instead of offensive counteroffensive operations. After repeated weapon deductions, the military believed that as long as the defense was obtained, it was estimated that it could barely resist the opponent's attack.

The precondition was that Qin needed to fund a number of new weapons, or defensive weapons, to help Yan build such a defensive line. After hearing this, Shang Wen nodded. That's all we can do for now. Because it's too late. Mercenaries are easy to find. In the north there are a lot of mercenaries. There are also many people in Zhao Guo. Many of them like to fight wars to make money.

However, in terms of weapons, Shang Wen believes that the Qin State has not provided much assistance, after all, the war in the Western Regions has not yet ended, and some obsolete weapons have not yet been shipped back. In the case of manufacturing, military orders are required. Military orders need to be done by the Yan people themselves. The question is, do the Yan people still have money in their hands? Shang Wen had to ask Ji Xin this question. Because only money can defend the borders.
