"Your Majesty, what is this, what is this?"

Looking at the disappearing mountain, Yue Fei was stunned and couldn't believe his eyes.

Originally, the power of explosives was shocking enough. On the battlefield, with the advantage of explosives, they won many victories.

But at the moment, everything in front of us is really incredible, and Yuan Ying's realm practitioner's all-out attack is just like this.

How many yuan infant level masters can a dynasty have, and how many opportunities can a dynasty have to make such attacks on the battlefield.

However, if such an attack can be released anytime and anywhere, it would be unthinkable.

"Star cannon."

Li Xian replied that he did not expect that this thing could play such a huge power.

"Your Majesty, can this star cannon be allocated to our green dragon army?"

"No, your majesty, this star cannon should accompany us white tiger army."

"What do you mean when we basaltic army doesn't exist?"

Li Xian was amused to see that several generals, like children, wanted the ownership of the star cannon.

"Well, this star cannon is not the only one. I've ordered people to hurry up early. Soon, this star cannon will become the standard weapon for the army of the Tang Dynasty."

Li Xian said.

"Really, your majesty."

"Your Majesty, what is the range of this star cannon?"

"Your Majesty, can this star cannon be fired continuously?"

The generals were immediately overjoyed to hear Li Xian's words, but all kinds of problems immediately came to them. They were all veteran generals in the army. Naturally, their first reaction was to understand the attributes of the star cannon, and then they were able to specify how to use it.

"Well Yue Fei, you have to test the attributes of the star cannon. By the way, the existence of the star cannon must be hidden. Do you understand? "

Li Xian had no choice but to give the task to Yue Fei.

Li Xian opened his mouth, and the generals didn't say much. They looked at Yue Fei one by one, and their eyes were full of eagerness.

Later, Li Xian ordered the Ministry of industry to speed up the manufacture of star cannons. At the same time, he also used the system to continue to submit materials for manufacture.

However, Li Xian soon found a big problem.

The power of the star cannon is really extraordinary, but the materials needed are also very huge. With the strength of the Tang Dynasty, it can only produce more than ten guns.

The main reason is that some of the materials are very difficult to find.

As a result, Li Xian had to order the work department to improve according to the drawings and try to use other materials instead.

"It seems that it's time to put the exploration of canghuan domain on the agenda."

After several unsuccessful explorations, Li Xian knew that some of the materials needed for the star cannon were not produced in cangxuan region and Cang region. According to some businessmen, there seemed to be a lot of canghuan region.

The idea that Li Xian didn't intend to provoke canghuan was broken.

After thinking about it, Li Xian finally decided to explore the snow.

Although canghuan domain is a huge object that the Tang Dynasty can't provoke, the power of the star cannon is really expected.

Although the star cannon is not easy to move, it is almost invincible in defensive warfare.

If the bombardment goes on, the practitioners of Yuanying realm will also be injured.

Although the Cang region has not been completely assimilated, it is basically stable, and it is not impossible to develop towards the Cang magic domain.

Thinking of this, Li Xian asked Di Renjie and Liu Bowen to make plans.

Almost sleepless day and night, a relatively conservative plan slowly formed.

Nowadays, the seven legions of the Tang Dynasty perform their respective duties. Yue Fei's Qinglong army and Zhou Yu's Qilin county are stationed in Shanhaiguan and canglanjiang, while Li cunxiao's white tiger army and Mei Changsu's red flame army are stationed in Cangzhou.

Xu Da's basaltic army stationed in Chang'an was certainly immovable, while Chang Lin's army and Xue Rengui's Zhuque's army were responsible for the support and overall planning of various places.

There is no doubt that this is the consequence of controlling Cang area too early, and the core forces of the Tang Dynasty were a little stretched.

But Li Xian didn't want to expand the army in a hurry.

The reason why the army of the Tang Dynasty is invincible is that the soldiers and generals in the army are all elite, and the second is that they have absolute loyalty and sense of belonging to the Tang Dynasty, which can not be cultivated in a hurry.

In the end, Li Xian decided to let the Tianshi mansion cooperate with Liu Bowen to stabilize the local Xiushi sects. At the same time, the Ministry of war organized reserve troops in the local prefectures, so as to temporarily liberate Xue Rengui's Zhuque army.

At the same time, Li Xian also wantonly built the post station.

Although the practitioners have a way to transmit information quickly, it can't be popularized and consumes a lot of money. The post station is still a once and for all method.

With Chang'an as the center, countless post stations began to be built one after another. Li Xian wanted to make sure that the information of each region could be quickly transmitted, and at the same time, let the Qing Dynasty cooperate with him, so as to stabilize the Cang region as much as possible.There is no doubt that this practice is still a bit risky. Once the expansion towards the canghuan domain is blocked, and there is turmoil in the latter side, the Tang Dynasty will fall into the situation of being attacked from both sides.

But Li Xian thought it was worth a try.

So the mighty army of rosefinch began to march towards the snow plain.

If the Tang Dynasty wants to enter the realm of canghuan, Xueyuan is the only way. The first task of the Zhuque army is to establish a camp in Xueyuan to connect with the rear area, and then slowly build the city to make Xueyuan a part of the Tang Dynasty.

Of course, this kind of thing is very familiar with the coming of the Tang Dynasty, and has even been done many times. It is not rare to build cities overnight on the way to war.

It can be said that they are proficient in various ways of building cities.

Xue Rengui also did his homework during his trip to the snow plain. With Li Xian's full support, he had everything he needed.

However, although they entered the snow, difficulties appeared one by one.

It's different for an army to move forward and a single Royal Guard expert to pass through.

The people sent by the royal guards several times were all elite practitioners. Although the snow was cold, they could bear it, but most of them were ordinary people, and their realm was not high.

The cold in the snow makes it difficult for them to move, and even lose their lives.

In addition to the bad weather, the north wind howling, the snow all over the sky, Xue Rengui can't tell the direction at all. Xue Rengui's forward speed is much slower than expected, and the supply consumption is also faster. Even in recent days, he has been frozen to death and frostbite.

What's more strange is that when Xue Rengui lightened his supplies these two days, he found that their supplies were inexplicably reduced. ..
