Li Su has been very busy lately.

Because there are some things that can be solved by the system mall.

And there are some things that can't be solved by the system mall.

For example, in the development of Datang, we must vigorously develop science and technology, cultivate a large number of scientific and technological talents, and develop and progress through research and invention.

The development of science and technology can be said to be innumerable, but there is one species that is indispensable.

That's rubber.

In the future, whether it is to make automobiles, cannons and other weapons, rubber is indispensable.

Everything else can be made.

But only rubber can't be created out of nothing.

The manufacture of rubber requires raw materials, and these raw materials are produced from rubber trees.

The origin of rubber trees is in the West, and there are no rubber trees in Datang at all.

Therefore, Li Yu exchanged a batch of rubber trees in the mall and ordered someone to plant them in a suitable place.

Just when Li Su commanded the people and was busy with their work, Xiao Liuzi came to report that it was the Qincha Kong Yingda who came again.

Hearing the news, Li Su couldn't help but feel tired.

What is this old man doing? What about playing?

I just left yesterday and I'm back today!

Is there anything you can't say all at once?

Running back and forth like this, aren't you tired?

But there is no way, who makes the family a chincha?

Li Su had no choice but to put down the work at hand and go back to receive Kong Yingda.

At this meeting, although Kong Yingda, the old man, had a dusty face and a tiredness that could not be concealed, he smiled and seemed to be in a good mood.

Well, I guess this time the will may be a good thing.

"The King of Shu takes the order!"

……

Soon, Li Su received the holy decree.

What he didn't expect was that this holy decree was actually to restore him to the post of envoy of moderation.

I just took away his official seal just before yesterday, and I sent it back today.

Are you kidding?

Soon, Li Su learned the truth of the matter from Kong Yingda.

It turned out that Tuyuhun really attacked Liangzhou, and Liangzhou assassinated Shi Lu Hao, a soft egg, who abandoned the city and fled.

The people of the two villages in Liangzhou were slaughtered, and the people of the Tang Dynasty in Liangzhou City must also be in dire straits.

Li Su's speculation has come true, and he has now been reinstated.

The Liangzhou assassin who impeached him must be severely punished, and the eldest grandson Wuji and Gao Shilian are also disgraced.

It stands to reason that Li Su should be happy.

But at this time, Li Su couldn't be happy no matter what.

Damn Tuyuhun!

They must be taught a hard lesson.

Even Li Su can guess that behind Tuyuhun's attack on Liangzhou in the Tang Dynasty, there will inevitably be a figure of Tubo.

Now that Tuyuhun has made a move, he must guess Tubo's next move.

In the original historical trajectory, the Tibetans attacked Yizhou.

Therefore, Li Su must beware of the attack of Tibet.

At present, the Songtsen Gampo of Tibet has completed the unification.

The strength of Tibet is constantly developing and growing.

The population of Tibet reached one million, and the number of young and middle-aged people was about 200,000.

And the people of Tubo are fierce, not to mention that all the people are soldiers.

Of course, it was naturally impossible for him to mobilize all the young men to fight.

In this case, there is no young man in his country, and sooner or later he will finish playing.

But 100,000 soldiers and horses can still be gathered.

If Tubo launches a national attack on Yizhou, then Yizhou is really very dangerous.

However, now Yizhou's army is also 7,000 people.

Li Su believes that it will not be a problem to hold on for at least a month.

The Tibetan soldiers, on the other hand, were not good at siege warfare, and it was impossible for them to continue attacking for a month.

Therefore, defending Yizhou City, Li Su did not have much to worry about.

However, what Li Su wants is not just to defend Yizhou City.

Instead, we must find a way to strike a heavy blow at Tibet.

You said you would stay at home honestly, and you would just build roads.

Now you run out and shout, who will build the road?

Now Li Su regrets that he does not have a perfect intelligence system.

Li Su, who came from later generations, was not unaware of the importance of the intelligence system.

It's just that Li Su has the shadow of Li Shimin by his side.

If he really wants to build an intelligence system, he will inevitably be known to Li Shimin.

What do you want to do as a prince who is engaged in an intelligence system?

In this way, it will inevitably arouse Li Shimin's scruples and will lead to unpredictable consequences.

Li Su ordered Xue Rengui to continue to strengthen the detection of Tubo's movements, while Li Su himself was thinking about how to deal a heavy blow to Tubo.

……

And Kong Yingda, the old man, was not in a hurry to go back after reading the holy decree this time.

Anyway, the emperor gave him a month's vacation, and Kong Yingda was ready to go shopping in Yizhou this time.

Yizhou is really a good place to recuperate, and Kong Yingda likes it very much.

On this day, Li Su checked Xu Hui's body again.

Well, of course, Li Su used the functions of the system to check for Xu Hui.

If a single round of medical skills is concerned, let alone Li Su, even if the divine doctor Sun Simiao comes, he can't diagnose Xu Hui's recovery.

The results of the examination surprised Li Su.

Because of Xu Hui's recovery, it was surprisingly good.

The average leukemia patient, even after bone marrow transplantation, has a certain chance of developing such and such problems.

There are really very few people who can be completely cured.

And Xu Hui's situation happens to be among the few proportions.

When you hear that your recovery is good, you will observe for another month or two, and if there is no problem, you will not need to observe it again in the future.

Hearing the news, Xu Hui couldn't help but be overjoyed.

For a child of seven or eight years old, with this disease, she could lose her life at any time, and the pressure she was under before was too great.

And now, I can finally breathe a sigh of relief.

"Alright, alright! Great, cute! ”

Well, it's not the man who said this, it's the parrot.

Last time, in order to save this parrot, Li Su upgraded it once.

This parrot is already smart, but after leveling up, it becomes more and more amazing.

In Li Su's Jiedu Envoy's Mansion, it was hot to talk to almost everyone.

Everyone, very fond of this beautiful, intelligent parrot.

Well, of course, there is one exception, and that is Doudou.

Because Doudou almost bit the parrot to death at the beginning, the parrot hates Doudou very much.

Then, it will often fly on Doudou's head to poop while it is sleeping.

When Doudou wakes up, he is furious and finds the parrot to take revenge on him.

This parrot would fly to Qin Mengxin or Xue Xiaoxiao to complain.

"Master mother, help, that dead dog is going to bite me, hurry up and save me!"

Then, Doudou will be beaten violently......
