Seeing Yang Kai's hesitation, Zhao Fengnian continued: "now many of the heavy cavalry are seriously injured, and some of their brothers' bones can't always be carried in the desert. In addition, the spirit beast horse also needs you to take back

After listening to Zhao Fengnian's words, Yang Kai nodded and bowed down.

Then Zhao Fengnian said goodbye to Yang Kai, Wu Yu and others. Zhao Fengnian took 500 heavy cavalry and Wu CAI to the depth of the dead desert.

Yang Kai and Wu Yu, on the other hand, follow the map drawn by Zhao Fengnian and walk towards the edge of the desert.

As Zhao Fengnian said, after an hour's journey along the map, the yellow sand under their feet gradually turned into barren grassland.

Seeing the long lost grassland, Yang Kai and Wu Yu know that they have finally returned to the grassland.

However, not long after Yang Kai and others stepped into the grassland, the sound of horses' hooves came from the distance.

Yang Kai and Wu Yu were shocked when they heard the sound of horses' hooves.

Is it not that the pursuers of the nether wolf tribe have been guarding here all the time?

However, after looking far away, Wu Yu put down his heart and waved desperately to a group of cavalry who were fast approaching in the distance.

It turned out that this was not the cavalry of the wolf tribe, but the king of the goshawk learned that the people might have entered the desert.

Therefore, some people who stay here are responsible for finding traces of Zhao Fengnian and others.

Later, we learned from Yang Kai and Wu Yu, the generals in charge of guarding Weiyang tribe, that the soldiers of the Ming wolf tribe in Weiyang tribe had been destroyed by the king of the eagle himself.

Now the goshawk king is leading a large army to fight the wolf tribe on the front line.

Knowing this, Yang Kai and Wu Yu rode quickly to the junction of the eagle tribe and the wolf tribe.

But even if the speed increased, when they arrived at the front, it was already the night of the day.

At this time, the eagle king was leading his soldiers to confront the garrison of the wolf tribe.

At the beginning, the army led by the king of goshawk was indeed caught unprepared by the wolf tribe.

But before long, the king of the netherworld rushed to the front with his own soldiers, facing the eagle king from afar, and the two sides began to confront each other.

Wait until dawn the next day before fighting.

After learning that Yang Kai and Wu Yu are back, the eagle king, who is analyzing the fighting power of the wolf army in the camp, goes out to meet them.

The goshawk king looked at the two men, and quickly asked, "can the Lord of Yongfeng be unimpeded?"

When Yang Kai saw the eagle queen, he bowed down and saluted, "the eagle king, thank you for thinking about it. Our leader is in a good condition now, but he has other things to do. He has to go back home first. "

Wu Yu next to him bowed down and said, "Wang! This is a letter from the Lord of Yongfeng. Please read it in person. "

The eagle king looked at them suspiciously, knowing that Zhao Fengnian had nothing to worry about.

But what's the urgent need to return alone? With doubt, the eagle king opened the letter Zhao Fengnian wrote to him.

In the letter, Zhao Fengnian told the story in detail, but he didn't say anything about what happened in the underground mausoleum or the Dragon God.

Zhao Fengnian just said that in the process of looking for the magnet and exploring the royal mausoleum, he accidentally found a map.

Zhao Fengnian did not conceal the precious resources marked on this map.

Because Wu Yu had seen the scroll, Zhao Fengnian didn't hide anything about it.

When the eagle king knew that there were so many precious resources in the desert, he was also shocked.

But why did Zhao Fengnian tell himself about it?

With doubt, the eagle king looked at Zhao Fengnian's words below.

After that, Zhao Fengnian put forward the idea that the two sides would cooperate to exploit some resources.

The death desert is very close to the goshawk tribe, but far away from Yongfeng.

Therefore, Zhao Fengnian couldn't send any people to the dead desert to mine. Instead, the eagle tribe was responsible for mining.

As Zhao Fengnian's ally, the eagle tribe is naturally the first choice to exploit these resources.

Of course, Zhao Fengnian will not provide the location of these resources in vain, and many of them are valuable resources that Zhao Fengnian can not let go.

Then Zhao Fengnian put forward a cooperation plan, that is, the eagle king provided manpower, and Zhao Fengnian provided the location and mining scheme.

Each side accounts for half of the resources mined.

In fact, it seems that Zhao Fengnian's conditions are somewhat harsh, and he suffers a lot from the eagle tribe.

However, the eagle king's eyes lit up with excitement.

Not every vein can be found so accurately, especially in the desert with complex terrain.

Now Zhao Fengnian can provide the exact location and some mining technology. The Cangying tribe is just making a little effort.

This is like picking up money for the king of the netherworld, and it is also a surprise.

However, what made the eagle king more surprised was still behind. Zhao Fengnian clearly pointed out the importance of magnetite and oil to yongfengling.Yongfengling hopes that the proportion of finished products extracted from these two resources will be 80% exclusive to yongfengling.

As a compensation for the goshawk tribe, Yongfeng can share the technology of manufacturing crossbow with the eagle tribe.

And in the future will be closer cooperation, gradually put more, more applicable technology.

This is a big surprise to the eagle king!

What I paid for was two kinds of resources that I had never heard of, but what I got was what the eagle king had always dreamed of - the formula of crossbow manufacturing.

Although the design of the crossbow is simple, some key points, if you do not know the material ratio and production method, will not be copied successfully.

This is the reason why Zhao Fengnian was able to promise to sell the crossbow to the eagle tribe.

Now Zhao Fengnian actually wants to share this formula with the eagle tribe, which shows that the eagle tribe can produce this weapon without restriction.

As long as the eagle king thinks that this kind of weapon can be equipped with the whole army, he is excited.

At that time, the wolf tribe and the grassland eight tribes will all collapse under the attack of the crossbow.

Forced to endure the impulse of soaring to the sky, the eagle king continued to look down.

In the following are some strategies given by Zhao Fengnian to the king of the goshawk against the wolf tribe, as well as the wolf deity in the hell wolf tribe.
