Not long after Ma Zhou and his entourage left the camp, Li Jing also sent fast horses to Chang'an.

In terms of speed, the fast riders in the army are unmatched.

He carried three of the fastest war horses, and there were four flags with Li Jing's name on his back, and the green light was all the way to the post station, and no one dared to stop him.

When the post stations saw this form of fast riding, they had to bring out the best fast horses of the post in the shortest possible time and prepare them, and at the same time prepare the food and fresh water needed by the heralds on the horses.

The herald arrives at the door of the post station, changes horses without entering, and continues to run to the next station, at which time the post station will be registered according to the information of the war horse left by the herald.

This is a complete logistics level information, the next station registers the information of the previous station, and finally all the information of the station can be matched, including the time in between.

And now the post station system of the Tang Dynasty is far from reaching its peak, especially in the slightly remote and desolate areas in the north, it is simply impossible to set up a post station for twenty miles.

Therefore, in this area, the herald often carries three horses, changes them on the way, and directly changes the three horses when they arrive at the next station.

The official rule of the Tang Dynasty was that ordinary letters must travel 180 miles a day, and the fastest one required 600 miles a day, if this speed, the fast rider sent by Li Jing, even if the weather factors were taken into account, the letter would be delivered to Chang'an before sunset on the third day at the latest.

But in that case, it basically means that this is the last mission of the messenger in charge of delivering the message, and after this mission, the whole person will be completely abolished.

Four small flags meant that they could travel 400 miles a day, which allowed the herald to take a short break on the way.

However, according to the usual practice, there will be no rest in the first part of the journey, and the fear is that the journey will be delayed, and if there is still plenty of time later, I will take a break for half an hour to make up for sleep or something.

Of course, this kind of opportunity is not very large, even if it is 400 miles a day, it is almost a day and night.

It took the herald two and a half days to get from Dingxiang to Chang'an, and when he entered Chang'an, he was almost asleep, and he didn't know from which post station he was bound to his horse to prevent him from falling.

Although his appearance was miserable, he had the highest right of way along the way, and the four small flags hanging behind him were Shang Fang's sword.

As for the car accident or something, even if it hits Fang Xuanling, the eldest grandson Wuji and other characters, then I can only be sorry, in order to maintain the rules, the emperor has to punish them painfully, although it cannot be the heaviest punishment.

So don't look at the second ancestor of Chang'an quite a lot, but when you see this kind of bigwigs who have flags behind their backs, they can still go as far as they can, who dares to stand up and put on the skin for a while, and the only way waiting for him is to behead him.

In the imperial study, Li Shimin, who had just finished the small meeting, heard a four-hundred-mile rush from Dingxiang Road.

Li Shimin frowned slightly, he was very clear about the fact that he would not accept military orders when he was outside.

So at the beginning of the fight, he entrusted it to Li Jing with carte blanche and even gave him a Shang Fang sword, so in general, Li Jing used an ordinary stagecoach to pass it.

The four-hundred-mile rush is an interesting choice, which means that this matter may not be urgent, but it is really urgent.

Could it be that something unusual is happening on the Turkic side?

"Summoning them back!" Li Shimin roared towards the door, and randomly took the bamboo tube containing the letter, with a fire seal on it, one side printed with the four complete handwriting of the immediate flying, and the other side printed with the words Li Jing.

After checking the seals on the lower two sides and confirming that they were all complete, Li Shimin nodded: "Help him go down to rest, reward!" ”

Li Shimin doesn't need to say what the specific reward is, unless he is in a good mood and specifies a reward, otherwise he will be rewarded according to the reward formulated in advance.

Opening the urgent letter, Li Shimin's eyes widened, he carefully read it three times, confirmed it over and over again, and couldn't see the slightest problem, this letter was indeed written by Li Jing, and the handwriting and seal were all right, but why didn't he believe the content of the letter?

"Your Majesty, but has there been a change on the front line?" Fang Xuanling and the others hurriedly turned back, and asked the reason on the way, knowing that Li Jing sent back an urgent report.

"See for yourself, why do I think it's a little fake?" Li Shimin handed the letter to Fang Xuanling.

"One hundred and twelve seriously wounded soldiers, four people who died normally without waiting for treatment, two people who died of allergies, twenty-two people who died normally after treatment, those who died without allergies, and the remaining eighty-four people, half of them are close to healing, and the condition of the rest continues to improve, only a little slower, the minister asked the reason, and Bo Ma Zhou, the lord of Zhao Wangfu, told the two boxes of drug users A and B to recover quickly, and the two boxes of C and D recovered slightly slowly.

The minister expects that the war will come after the year, and the pacification of the north is a foregone conclusion, and I implore His Majesty to order the delivery of this new medicine to the front line...... "The more Fang Xuanling reads, the more surprised he becomes.

"That's a wounded barracks...... Eldest Sun Wuji was dumbfounded when he heard this, and he was speechless by Yu Li Yuanjing's operation.

There is no need to talk much about the situation in the wounded barracks, they have seen and experienced it with their own eyes.

One hundred and twelve seriously injured and wounded soldiers, more than eighty can recover after treatment, and listening to Li Jing's meaning, it seems that if you treat it early, the effect may be better.

No wonder Li Shimin didn't believe this news, and they wouldn't believe it either.

"Summoning King Zhao into the palace!" Li Shimin instructed outside the door, the matter was done by Li Yuanjing, no matter how much they think about it, it is better to find Li Yuanjing and ask, and then everything will be understood.

"Your Majesty, I'm afraid these medicines are not cheap!" Eldest Sun Wuji shook his head with a wry smile.

"Hmm!" Fang Xuanling also nodded, and then analyzed: "With His Royal Highness King Zhao's money-loving character, now that he has this kind of treasure, he will never sell it cheaply, even if the cost is not high, he will definitely make others think that the cost is very high, for example, all participants, ten times per person, and all those who die, thirty times per person, just this test alone, he threw one or two thousand pieces into it, and Li Jing said that the drugs used were only eight hundred, and it was calculated that only one in this area used two pieces......

"Xuan Ling is too worried, that is just the price code given to let the soldiers accept the test, and it can be shared evenly later!" The eldest grandson Wuji said with a smile, he knows Li Yuanjing's methods too well, he has not been fooled in vain for so many years, and the two sons have not been used as dogs for nothing, he can't get anything, and he still needs these two dogs, no, what are the two sons doing?

"Even so, Your Majesty must be prepared in a consistent heart, and it is one thing whether or not you can even take it!" Fang Xuanling didn't care.

It's just a pity that Cheng Zhijie is not here at this time, if he is here, there is no need for Li Yuanjing to refute anything, Cheng Zhijie alone can spray everyone present to death.

A good thing to cure diseases and save lives, consistently? What do you think? Go home and dream!
