The crowd, who had completely lost hope, stood up in disbelief after hearing what Li Huai said.

Look up to the Liang King under the military flag.

"King Liang, can our army still be restored?" The general asked excitedly, and lowered his head embarrassedly after asking.

This is obviously impossible.

The military name and battalion number of their army do not belong to the Yu State, but are left over from the previous dynasty.

Restore the structure of their army, what will the imperial court think?

They will eventually be reduced to the dust of history.

"King Liang, you didn't say anything to me." The general bowed his head in discouragement.

Li Huai smiled, "Why can't the establishment be restored?" ”

Everyone raised their heads in surprise when they heard this.

Li Huai's eyes looked around everyone again, and everyone looked at him with tears in their eyes.

"Aren't you soldiers from my Liangzhou? Isn't this military flag my Liangzhou military flag? ”

"Don't you want to be a cool soldier?"

Facing Li Huai's three questions.

Everyone was stunned for a while, and then they all agreed, landed on one knee, slammed their fists on the ground, and bowed their heads and said:

"Swear allegiance!"

Li Huai held the flagpole, glanced at them, looked up at the military flag again, and said: "The reason why soldiers are honorable and why military flags are immortal is because of the duties of soldiers. ”

"Defend the family and the country!"

The soldiers shouted in unison.

"Within a month."

Li Huaisu said: "You will receive military salaries, military uniforms, and weapons, and restore logistical support." ”

Regardless of the actual commitment, it is all hooliganism.

"Within a year."

"Restoring the structure of your army and creating an immortal Liang Army starts with you."

"Hereafter!"

"The lights of thousands of homes in Liangzhou will never go out!"

Brush!

"The lights of thousands of homes will never go out!"

The soldiers shouted in unison.

"General's surname?" Li Huai asked.

"Returning to His Royal Highness King Liang, the minister's surname is Su, and his name is fixed."

Li Huai nodded, wrote down the name, and said, "General Su, in a few days, Princess Shangguan will come to visit you, and you can ask her for anything." ”

Although Su Ding didn't understand why it was Princess Shangguan who was in charge of them, the soldiers took it as their duty to obey orders.

"Yes!"

"Help me give her this letter along with it." Li Huai took out a letter and said, there was no goodbye, it was all in the letter.

Su Ding took the letter with both hands and kicked it in his arms, "Obey." ”

"Send some more people to escort this king back to Jiuyuan." Li Huai made the last request, the escort team was the old, weak, sick and disabled among them.

Their army can be restored, but some of them are really not suitable to stay in the army.

Iron battalions, flowing soldiers.

Li Huai didn't want to give up on them.

They can pass on the military spirit of the army to more people.

Li Huai planned to scatter these veterans all over Liangzhou and use them to transfer and recruit soldiers, so that the recruits could have direct contact with the veterans.

"Veterans don't die, they just wither!"

……

The day, dusk.

Tucheng opened a team of thirty or forty people, under the banner of King Liang, and walked east with great fanfare.

This scene was clearly seen by the scouts on the border in the Western Regions, and they reported it truthfully.

Didn't get any attention.

No one would believe that King Liang would be alone, facing the last rays of the sunset, and enter the Western Regions alone.

Even he had to travel through the entire Western Regions.

The Western Regions will not believe it, nor will the Northern Wilderness, and even the imperial court thinks that Li Huai really returned to Jiuyuan.

……

Great Wall Fortress.

"General, King Liang sent something again, I didn't believe it." Yang Dong held a box and found Yang Lingyun in Beichengtou.

Yang Lingyun was holding a long object, observing the Northern Wilderness, and what she was holding in her hand was the first telescope.

Li Huai engaged in the glass division, in addition to making money, just to engage in this thing, but the current technology is too backward.

The production of colorless, impurity-free glass with high transparency is a matter of luck.

Occasionally, you can get a few suitable pieces of glass, and in the process of polishing and grinding, you will lose most of it.

In the end, being able to produce a telescope is completely a matter of luck and luck.

However, with the deepening of research and development, glass workers are gradually becoming proficient, and it is only a matter of time before mass production is away.

Yang Lingyun's telescope was made by Li Huai before he arrived in Beidi County, and after thinking about it, he decided to use it for her first.

After Yang Lingyun received it, he couldn't put it down, and the sight that was obviously far away seemed to be within reach through the telescope.

This means that they can detect the enemy before they do, and they can even hide in a place where the enemy cannot see it from a long distance, and detect the layout of the enemy camp.

"You say you don't have faith?" Yang Lingyun slowly put down the binoculars and asked in surprise.

"I asked deliberately, but there is really no letter, I guess King Liang is too busy." Yang Dong made excuses for Li Huai.

Yang Lingyun raised his eyebrows, if Li Huai really returned to Jiuyuan, no matter how busy he was, he would definitely write to her.

There is no letter.

This proves that he did not return to Jiuyuan, and Li Huai's last public appearance in Liangzhou was on the border of the Western Regions.

"This bastard boy ......" Yang Lingyun's brows darkened a little, he was too desperate, what was he doing there?

"General, what's wrong?" Yang Dong asked curiously.

"Nothing."

Yang Lingyun covered up the past without a trace, changed the topic and asked, "What did he send this time?" ”

"The person who sent the thing said, it's called the compass, there are ten of them, and they haven't been opened yet, so I don't know what it is." Yang Dong explained.

Of course, the things given by Li Huai have to be opened by Yang Lingyun himself, who dares to see them in advance.

Yang Lingyun pinned the telescope to his waist, took the box from Yang Dong's hand, and nailed it with wooden nails.

She directly used internal force to suck the wooden nail out.

Then gently open the box.

半个盒子都是干草，干草上固定着十个巴掌大小的圆盘，还有一张使用说明书。

Yang Dong picked it up and looked at it, "It says that the red end of the compass can always point to due north, so magical!" ”

Yang Lingyun was also stunned, this little thing can determine the direction, and if the lone army goes deep, there is no need to worry about getting lost.

She picked one up.

It was placed in the palm of the palm, a thin disc the size of a palm, with some liquid in it, and a needle fixed in the middle, one red and the other black.

There is also a scale that divides the four directions into three hundred and sixty equal parts.

But......

The needle did not point to the north, but it was jumping with no regularity, and there was no intention of stopping.

Yang Lingyun picked up another one, and it was the same, the pointer was always moving.

Ultimately.

The ten compasses, all placed on the battlements, were all moving.

"Could it be that the road is bumpy and broken?" Yang Donghu doubted.

Yang Lingyun pondered for a while, shook his head and said, "It shouldn't be, the glass is intact, and it shouldn't have fallen." ”

"Then what's going on, how can this be clearly distributed." Yang Dong didn't think that Li Huai would make such a joke.

Send something useless.

Yang Lingyun thought about it, picked up two casually, jumped out, and flew out of the Great Wall.

"Be on guard!"

Yang Dong hurriedly shouted.

Although Beihuang does not dare to approach the Great Wall easily, it is still necessary to be careful.

As Yang Lingyun left a certain range of the Great Wall, the power of the Great Wall in her body disappeared, and the two compass suddenly jumped at the same time, pointing steadily to the north.

No matter how much she turned the disk, the compass always pointed in one direction.

Li Huai wasn't joking, this thing can really point the way.

"Then why can't it be done inside the Great Wall?"

Yang Lingyun was puzzled, she couldn't understand the principle of the compass, and of course she couldn't think of an answer.

She returned to the city wall and told Yang Dong the result, but Yang Dong couldn't think of a reason.

I have no choice but to give up.

As long as something works.

Yang Lingyun asked Yang Dong to divide the compass, command the generals to have one, and tell them the purpose.

"I don't know what good things King Liang will send next time."

Yang Dong began to look forward to it, every gift is incredible, the key is practicality.

"Last time he wrote to me and asked for drawings of all kinds of cannons." Yang Lingyun said silently.

"What else is there to study about the cannon, it's been more than a hundred years, it's still the same, although it's powerful, it's too bulky." Yang Dong said disapprerovingly.

To pull an ordinary cannon, you need to be equipped with a set of frames, and you also need a military horse, not to mention the slow speed, and you can't go to many terrains.

And that's not even counting the gunpowder and shells that go with it, and the soldiers who operate the cannons.

If it is convenient to pull the artillery out of the city, this echelon defense of the Northern Wilderness will spread the troops for hundreds of miles.

They could have put the muzzle in their faces.

Bomb their camp to rubble!

Forcing the Northern Wilderness Front to retreat a hundred miles, or stationing heavy troops in front of the position, no matter what it is, it can make the Northern Wilderness scold the aggrieved.

Of course, the current artillery can also do it, but there is absolutely no way to pull the artillery back before the enemy reinforcements arrive.

In order to destroy one of the enemy's camps, so many artillery pieces were lost.

Fool's talent!

Yang Lingyun laughed lightly, "He always likes to do things that others think are impossible." ”
