One winter is enough for Ye Zhao to make a relative understanding of Jianning, the coverage of Jianning County is very large, but only one percent of the land in the ninety percent of the mountains can provide a relatively peaceful environment for human beings, and the bad thing is that even in this part of the land, not all places are suitable for planting, even if there are manure, new ploughs and other agricultural tools, it is difficult to feed the Han barbarian population in Jianning County with only these limited land.

However, Jianning County has been established since the pre-Qin period, and it has been passed down for hundreds of years, and there are still people here to reproduce for their own reasons.

First of all, the climate is more suitable for human habitation than in the north, and secondly, although it is impossible to cultivate, among the vast mountains, there are abundant products, birds and animals, rare treasures, and rare plants can be found here, even in an undeveloped state, can feed these people, if you want to say that the potential, there is still there.

Whether it is Jianning or Zhuti County, which has been expanded by Ye Zhao once before, it is in a similar state, and it is not suitable for a large number of people to move in before the potential is tapped.

If this is to be improved, after the four counties are conquered, Ye Zhao will have to pay for the development of this southern Xinjiang land for at least twenty years in the future, and the food supply cannot be stopped, but correspondingly, he can obtain a large amount of jade, silver, iron and other minerals from Yunnan.

For the luxury goods of jade, as long as it is processed by jade craftsmen, whether it is the Central Plains or the Western Regions countries or even further away in Guishan and Kangju, it is a huge market.

Two years passed in Xingping, followed by the news from Chengdu/Du, Liu Xie changed the name of the year here, changed to Yuan Jian'an, which was the fifth year of his reign, and successfully escaped from the control of Li Dao and Guo Yan, fled to Luoyang, and rebuilt the imperial court in Luoyang.

In this regard, Ye Zhao can only hehe, the reason why he agreed at the beginning was not Liu Xie, but Li Dao and Guo Yan, the Silk Road is in the hands of the two, he needs the Silk Road to facilitate his own trade, and now Liu Xie has moved to Luoyang, for Ye Zhao, there is no practical value, how can Ye Zhao continue to waste food to help the court raise people?

Ordered someone to reply to the letter on the grounds that the road was not smooth, cut off contact with the imperial court, and at the same time sent people to contact Li Dao and Guo Yan, before he pacified the Nanban, continue to maintain friendly trade relations, but this cooperation method can be changed, after all, there is no righteousness of the imperial court, and Li Dao Guo Yan now also needs allies, so there is no need to waste 1.8 million stone grain and grass every year, you can send lobbyists to lobby, at the cost of 600,000 to 800,000 stone, continue to maintain the smooth flow of the Silk Road.

At the same time, Shuzhong's achievements in Xingping two years were also sent by airships like snowflakes, agriculture is still a bumper harvest, the rise of animal husbandry not only provides a large number of cattle, but also adds a lot of meat to Shu, the grassroots construction in Shu, at most in two years can be saturated, and then it is to prepare for Shu, Nanban here, two years, should be enough for Ye Zhao to settle down.

The climate in the south and the middle is warmer, the winter is not long, in January, the north is still in the middle of winter, the weather here has begun to warm up, and the mountains have begun to glow green.

"Lord, great joy!" Pu Yuan, the master of the Shengong Battalion, rushed in from outside the mansion with an excited face, and bowed to Ye Zhao.

"What's the joy of?" Ye Zhao looked at Pu Yuan in surprise and wondered.

"My lord, come with me, there has been a breakthrough in the technology of the flying boat." Pu Yuan said with a smile.

"Oh?" Hearing this, Ye Zhao stood up and followed Pu Yuan to the outside of the city, but saw that a flying boat that was more spacious than Ye Zhao's car was already standing in the open space outside the city, and there were many good things around the people who stopped and watched from a distance.

It's no secret that the Han army can fly.

"Bigger, what's the difference?" Ye Zhao looked at Pu Yuan suspiciously, if it was just to increase the volume, there was nothing peculiar.

"My lord, let's get on the flying boat and take a look." Pu Yuan smiled and took Ye Zhao onto the flying boat.

It is indeed different from before, the rope of the flying boat is implicated by iron chains, and a blower is made of a complex machine inside, which is used to manipulate the direction and speed of the flying boat, and the heating equipment looks more advanced, according to Pu Yuan, a layer similar to a filter is added to the heating port, which can effectively reduce the intake of dust, and if it is lamp oil or fire oil as fuel, the endurance time and distance will be longer.

The disadvantage is that both the machine and the heating equipment need to be replaced regularly, and there are a lot of wasted materials, and there are improvements, but it will not make him excited like this.

"Lord, look!" Faced with Ye Zhao's explanation, Pu Yuan took out a piece of paper from the cabin of the flying boat.

"Master Pu won't tell me that there is paper in the airbag of this flying boat, right?" Ye Zhao looked at Pu Yuan strangely, this is not a 10,000-year-old lamp, although the paper can indeed be made into a sealed space, but once the heat of the heating port is discharged, the paper in the interlayer can be ignited in the shortest possible time.

"This is no ordinary paper!" Pu Yuan explained with a smile.

"Oh?" When Ye Zhao heard this, he looked down at the paper in his hand, and pulled it, but he didn't pull it away, it was not the kind of paper used for writing, but it was more tenacious, and it was impossible to pull it apart, it needed to be torn apart, and it took a lot of effort.

Since Ye Zhao improved the papermaking technique, he handed it over to the Shengong Battalion to do, and he didn't care about it, but he didn't expect that in just a few years, they would make such a breakthrough on paper, but even so, this thing is also afraid of fire.

As if perceiving what Ye Zhao was thinking, Pu Yuan lit a torch and handed it to Ye Zhao, Ye Zhao took the torch and baked the paper, but he couldn't bake it for a long time.

"The ministers communicated with the barbarians in the mountains, and knew that there was a liquid made of a number of grease supplemented by various ingredients on the object, which could be fireproof, and the ministers developed it, and smeared it on this paper, so they got this thing, which is not only fireproof, but also waterproof, and can save the leather, and directly use this paper as the inner bag, and attach the cloth outside, which is not only light, but also more tough than before." Pu Yuan said to Ye Zhao with some excitement.

"There's such a thing!" Ye Zhao's eyes lit up, if this is the case, then why didn't the rattan armor of the Southern Barbarians cross this thing?

"It's just that this thing is insoluble in oil, and the ministers originally wanted to soak the paper in oil, and then cross this strange thing, which can make the paper tougher, but who knew that this thing actually slipped off directly, and it was difficult to attach." Pu Yuan said with some regret.

"That's all there is to it!" Ye Zhao looked at the paper in his hand, shook his head and exclaimed: "The wonder of this creation is really amazing, can this thing be mass-produced?" ”

"Not for the time being, there are very few strange trees, and the liquid produced is only enough to make this flying boat, the ministers are trying to cultivate its branches and leaves, if this plant can be cultivated, it can be mass-produced, the lord and look at this layer of fine net, it is also a silk thread to cross this thing." Pu Yuan excitedly pointed to the layer of filter at the heating port and smiled.

Ye Zhao took people to look at it at the moment, but it was an ancient tree, no matter in his previous life or present life, he had never seen it, and he couldn't help but be curious: "Do you know what kind of tree this tree is?" ”

"I don't know, why don't you give the name of the lord?" Pu Yuan said with a smile.

"If it can prevent fire, let it be called a fire tree." Ye Zhao said with a smile: "The people who know how to cultivate plants in the Divine Engineer Battalion will come as soon as possible, if this thing can be planted in batches, it will be of great use to our army!" ”

"Whoa!" Pu Yuan nodded excitedly, this new flying boat is not only light airbags, but the load capacity is much higher, not only for the march, many constructions in Shuzhong, such as the construction of bridges between many mountain streams, the transfer of materials will be much more convenient, as for the use of war, like this flying boat, it can carry thirty people without being crowded, and can even set up crossbow arrows, when attacking the city, throwing stones can kill people, not to mention reconnaissance, it is too useful.

Sending away Pu Yuan, who was excited, Ye Zhao returned to the city, the breakthrough in the technology of this flying boat is indeed gratifying, but before the mass production of the fire tree, all this is just a fantasy, and it is not accurate, and the airbag is still too fragile, Mo said that he was shot by a bow and arrow, even if he was pecked by a bird in the air, he couldn't stand it.

The next time was calm, the grain and grass in Shu continued to be sent through Zhu Ti, Jianning's army after two months of training, it was almost over, at the same time, Zhu Ti and Jianning provided winter materials, absorbing a lot of barbarians to vote, at the end of January, the owner of the Ba Na Cave Duo Silai wanted to sneak attack several times, after being defeated by Zhao Yun, he finally couldn't support it, and chose to surrender to Ye Zhao, and it was also outside the Zhurong Cave in southern Xinjiang, another group of barbarians who accepted naturalization.

At the beginning of February, the three counties, which had been dormant for months, finally got the news.

In the Taishou Mansion, Huang Quan, Guan Yu, Xu Rong, Zhang Liao, Zhao Yun, Guan Hai and other generals came to the hall with serious expressions.

"Lord, Zhu Ti, Niu Lan Mountain, and Leaky River all sent information, Zhou Chong, the king of Yuewang, led a total of 20,000 barbarians in the twenty-four caves of Yuewang to capture Tangwolf, crossed Zhuti Mountain, and approached Zhu Ti, wanting to cut off the way back of our army, in addition, the Yi Meng Shu colluded with Yongchang and Qiqi two counties, and took two roads with a total of 50,000 troops to attack!" Huang Quan bowed to Ye Zhao and said solemnly.

"After two months of hibernation, this is to gather the southern barbarian army, and attack them all!" Ye Zhao shook his head and laughed: "In this way, it also saves a lot of trouble. ”

"Lord, the thief army is attacking from three directions, and Zhu Ti only has 3,000 men and horses, and I am afraid that it will be difficult to defeat the 20,000 Yue Net!" Guan Yu was worried about his beloved son, and said to Ye Zhao: "The last general is willing to lead three thousand soldiers to help." ”

"Don't panic!" Ye Zhao shook his head and said: "Don't forget that Zhu Ti still has 30,000 Zhurongdong warriors, Tan Zhi is here, Zhu Ti can be guaranteed, and he ordered someone to inform Tan Zhi, just hold on, and wait for our army to defeat the enemies of Yongchang and Qiqi counties, and then return to the army to clean up the king of Yuewang!" ”

At the beginning, Ye Zhao left Guan Ping so that Guan Ping could call on the warriors of the Zhurong clan to participate in the war at a critical time.

"Our army has 30,000 soldiers and horses in Jianning, and Meng Shu gathered 50,000 troops to attack, just in one go!" Xu Rong stood up, bowed to Ye Zhao and said, "Lord, the last general is willing to lead the army to meet all the way!" ”

"Yes, when your 10,000 army rushes to Niulan Mountain to defend against the enemy, I will lead the army to the Leaky River, Zilong, and among the Southern Barbarians, there are also brave generals, and you will travel with Xu Rong to help him." Ye Zhao looked at Zhao Yundao.

"The last general commands!"
