The red-crowned crane streaked across the sky, leaving a faint shadow before disappearing directly into the white clouds on the horizon.

After having a goal, Lu Hanyang hurried quickly, and it only took one day to return to the Guanzhong area from the Saiwai grassland. This time he once again went astray with honor, because he went straight, so now he is hundreds of miles away from Chang'an.

At this time, he came to the vicinity of Luoyang, the eastern capital, which was six hundred miles away from Chang'an. But when you arrive in Luoyang, will Chang'an be far away?

So he stopped and rested for a while, of course, mainly the red-crowned crane rested, he basically didn't move, where did he need to rest!

I rested in Luoyang and had a meal at the best restaurant in the city, and it was almost dusk. He didn't plan to continue his journey now, after all, he had already arrived in Luoyang.

And Li Jing's eight-hundred-mile expedited is probably just entering the territory of Datang now, which is the speed advantage of completely crushing.

Of course, this is not Lu Hanyang's limit speed, his current limit speed is probably Biao Feijian. With more than a thousand True Yuan, he could fly the sword all the way from the grassland back to Chang'an.

In that case, it would be almost an hour to complete the journey. The road of more than 2,000 miles, that is, more than 1,000 kilometers, is twice as fast as those ordinary passenger planes in later generations.

It's just that the current Lu Hanyang is not ready to fly the sword remotely, because the flying sword is too expensive to consume the true yuan, and it will take him several days to recover his full blood state after flying down this more than 1,000 kilometers.

So it's not a particularly urgent thing, he won't do it, and now it's fast enough to ride a red-crowned crane.

After resting in Luoyang for the night, when the sun rose the next day, Lu Hanyang hit the road again. This time he flew directly along the official road, and the official road from Chang'an to Luoyang was relatively straight, and there would not be many turns.

"Chang'an...... I'm back again! Go to the palace first, and then go back to Yushan! Lu Hanyang conveyed his thoughts to the crane under his crotch.

"It's the Pure Yang Immortal who has returned...... Go and report to Your Majesty! The guard at the gate of the palace saw the red-crowned crane flying from the sky at this time, and immediately explained to the deputy general beside him.

"No need, just go in by yourself, and you will continue to work." Lu Hanyang stopped the city gate army who wanted to report the news.

"Immortal Chief, please ......" The gatekeeper got out of the way, who didn't know that this immortal was the biggest golden thigh in Datang, and whoever hugged it was really one step to the sky. It's just that the gods won't accept people easily, and the two boys are not ordinary people.

"Your Majesty, this is the distribution map of the Chi Road that has been built now, spreading outward from Chang'an, it is expected that it will be able to be repaired to Luoyang in three months, and it will be possible to reach Luoyang in one day from Chang'an to Luoyang!" Fang Xuanling was reporting to Li Er.

"The output of this cement should be tightened up, there is a great demand for building roads and city walls for this thing, I hope that all the cities in my Datang will be poured with cement, so that it will really be regarded as a city that does not fall into the city!" Li Er said.

"Your Majesty, this minister will hurry up and do it, but this crushing limestone is a thing that cannot be tricked, and it can only be crushed by manpower, which is really time-consuming and labor-intensive." Fang Xuanling said.

"I just don't know if this concrete-poured wall can withstand the bombardment of gunpowder! I wanted to see if the walls made of concrete were hard or the gunpowder was indestructible! Li Er thought of the gunpowder piled up in his Taicang.

"Your Majesty, this ...... I'm afraid that gunpowder can blow down the concrete wall, and of course it will require a large amount of gunpowder. Eldest Sun Wuji said after estimating on the side.

"Your Majesty, the Pure Yang Immortal is back!" Lu Hanyang did not hide his traces, and the small yellow gate outside the hall had already seen him riding on the back of the crane at this time, and went in to report to Li Eryu.

"Immortal Chief's back? The triumph of my Tang army is imminent! Li Er showed a smile on his face, Lu Hanyang came back, then it means that the matter on the grassland has come to an end.

Li Er knew part of the results of the Tang army, that is, Cheng Yanjin and Wei Chigong had already won, and the grassland only knew the first big victory, but he didn't know what the specific situation was, and the good news was very vague.

At this time, the communication was very underdeveloped, and from the grassland to Chang'an, it took about a week to run 800 miles in an expedited manner. So now that Li Er heard that Lu Hanyang had returned, he immediately wanted to ask.

With a large group of civil and military officials heading out of the door, he was going to greet the immortal, whether it was because of the good news of the army he had brought back or something else.

"The immortal chief has returned, and it has been hard all the way!" Li Er stepped forward and saluted Lu Hanyang.

"The Emperor is gracious! This seat came this time to discuss with the emperor. Lu Hanyang said, that thing was in his arms, and he had been enduring it for more than a day, almost to the limit.

"Immortal Chief, please say, if you can do it, you will never refuse!" Li Er said.

"Emperor, please see...... What is this? Lu Hanyang took out the box containing the heirloom jade seal from his arms, this thing he tried and couldn't receive the storage ring, it was definitely not an ordinary thing.

"It's ...... This...... Could it be that this is the jade seal of the country! When Li Er saw the things that Lu Hanyang took out of the box, his eyes immediately straightened. It's something he's been dreaming of, and it's finally here.

"This thing, this seat has to study it for a while, the emperor has no problem, right?" Lu Hanyang said.

"This ...... Why did the Immortal Elder study this thing? Li Er looked embarrassed.

"Of course, this thing is very peculiar, and this seat needs to be studied carefully." Can Lu Hanyang tell him that it's just a feeling? So that's all I can say.

"Immortal Chief, you should know that this is the jade seal of the country, a symbol of imperial power, I'm afraid it ......" Li Er was obviously reluctant. Who knows how long this immortal will be studied? And will it be broken?

This is the same thing as the emperor's ID card, it is definitely not an ordinary gadget, for Li Er, this is a huge bargaining chip for whether he is the orthodoxy of the Central Plains Dynasty.

Because although he ascended the throne, first, the way he got the throne was a little irregular, and secondly, although his Li family climbed to the Longxi Li family, their bloodline was indeed impure.

This made Li Er attacked by those big families with bloodline again and again, so he wanted to use the heirloom jade seal to fight back, but he met Lu Hanyang.

"I don't dare to give you any guarantee to the emperor, because I don't know where my research has returned, but if I really study this thing, I will give you a new one!" Lu Hanyang said.

This answer almost didn't make Li Er fall directly, can you replace the original one if you make this thing yourself?
