On a starry night, the Prince's Mansion was busy all night.

Orders to mobilize food, clothing, and supplies from various places were constantly issued, and sometimes people left the prince's mansion and ran everywhere.

The atmosphere in the prince's mansion was solemn, and Li Jiancheng wore the crown of the prince, walking back and forth on the ground anxiously.

The temperature was still not high tonight, but the thick carpet on the floor and the few stoves in the room did not bring him any warmth, only a cold inside.

He didn't know what was going on, Li Shimin had changed his previous decline in the past few days, and suddenly moved back to his previous disadvantage.

Could it be that his scheming is as terrifying as his ability to fight?

Li Er's exploits, as well as his performance on the battlefield and prestige in the army, kept drifting back in his mind, and Li Jiancheng's body couldn't help but tremble.

If this is the case, he can't wait to kill Li Er immediately and let him live one more stick of incense, which is a huge threat to himself!

"What the hell is going on, Li Gang, Dou Rail, Feng Li, you give me an analysis and analysis!" He said through gritted teeth.

All day today, he felt that he was stunned by Li Er, did he know that it was going to rain heavily yesterday?

Otherwise, why prepare a large amount of supplies in advance?

One day yesterday, the profiteers in Chang'an City hoarded Juqi and immediately began to hoard goods and raise prices, refusing to sell grain.

And the traffic everywhere was also blocked by the torrential rain, and the ground was muddy everywhere, and the horse-drawn carriages would sink from time to time as they walked by.

It was only at night that the situation on the ground improved slightly, and he was able to mobilize supplies.

However, Li Er has been a good person in Chang'an for a day, and I don't know how many people have received his favors, and he will go out tomorrow to make porridge, as if he is robbing him of Li Er's credit.

Damn, it's obvious that this bastard is a sideways stick and robbed him of his errand, okay!

Li Gang tightened his face: "Actually, in the final analysis, it's very simple, that is, he doesn't know where to get some strange things, which won the favor of His Majesty and the concubines, and his momentum in the court has changed immediately." ”

"Yes, how many years of hard work I have waited for, it can't compare to a few foreign things, hateful, pathetic."

Everyone sighed, feeling unusually worthless.

"Could it be that he found some strange person?"

Li Jiancheng is not stupid, he doesn't believe that Li Er is the material for invention, and there must be a master behind it.

"Eighty percent is, today a spy said that King Qin unusually appeared in Xinghuafang, as well as Wei Chigong and others, and all his henchmen are there."

"Give me a good check, and tomorrow's relief and other things will also give Prince Ben all his strength, no matter what, let Chang'an hear my Li Jiancheng's voice, otherwise I will really make him a wedding dress!"

"......"

At this time, the restaurant is in its own room.

In front of Chen Xu is a black slender cylinder, the outside is plastic, reflecting some smooth and glowing materials under the light, and there is a thin plate on its body that can be unfolded, which is a miniature solar panel.

Chen Xu turned on the light with a click, it was weak light at this time, and the irradiation range became larger, and a layer of light was irradiated in most of the arc in front of it.

Then I pressed it again, this is a strong light, the irradiation range becomes smaller, the cohesion becomes stronger, but the irradiated place is bright.

"Haha, it's a boutique at first glance!"

Chen Xu smiled with satisfaction, he didn't work in vain today, and he could see that Li Er and they were also working very hard, and the number of victims treated in one day reached more than 80,000, including almost all the victims in Chang'an City, and the rewards should come from time to time.

He has seen this flashlight in all aspects, it is sturdy and durable, fast charging and high power, and the most important thing is that it is small and does not take up space, and it can be strangled by the belt when it is inserted into the waist, and it is not worried that it will fall.

Its exchange price is much more expensive, five hundred civilizations are worth one, he temporarily exchanged five in one breath, and after taking one himself, he pushed the remaining four to the two people in front of him.

The signature dish of the night market appeared again, Chen Xu's efforts did not fail, and the cucumber shooting smoothly brought him two new talents, the same is one force and one technology.

It's just that the two people this time are different from the two during the day, the force type is thin and small, and they take the road of agile spying, but the technology is a big and tall strong man.

It can be seen that the system is still very practical, knowing that whether it is technology or security, it needs to be comprehensive and take into account various considerations.

"If you go out of the city overnight, you will say that it is the people of the King of Qin, and the people guarding the city will not embarrass you, so you rushed to Wannian County to meet with Gao Di Zhangjiu in the starry night, and distributed the flashlight to them, and the four of you took care of the warehouse over there."

The two of them took the order and left, each with some things, and left the city at night.

And Chen Xu took this flashlight, stood outside Aaron's room like a mischief, shining the light through the window, and Aaron, who was not asleep inside, screamed.

Sitting up with the quilt in her arms, she vaguely saw Chen Xu's figure from the light, and then she looked a little calmer, but she was still scared enough.

She hurriedly ran to open the door and let the abrasive spirit in.

Chen Xu handed her the flashlight to play with, wanting to see what the ancients thought of this thing.

Aaron played carefully, pointed his way to a corner where he could barely see anything at all, and pressed the low-light switch.

The whole room is suddenly bright, which is the benefit of low light, because the irradiation range light makes it easier to brighten the whole area without affecting normal activities.

"That's amazing...... Master, how did you do that? ”

Aaron's whole back was numb in shock, and her heart was about to jump out of her chest, she felt that the master had locked the lights in during the day, and then released them at night?

But it's too bright, and the light doesn't seem to be so bright during the day.

"It's troublesome to explain this, you don't understand." Chen Xu decisively gave up giving people electricity and the like, at least he doesn't have this plan now, and he will talk about it when he changes enough to Datang in the future.

If we can really cultivate talents who are proficient in electric power, it will completely solve a series of huge problems, so that Datang can quickly bury itself directly from the feudal dynasty to the stage of industrial countries, of course, it is still too early.

In terms of this kind of popular work, Chen Qin and Zhang Jiu must be better than himself, and he doesn't have to worry about teaching Tang people at that time.

"You can try it everywhere, don't worry, there's plenty of light in here, and it'll be fine for at least a few days."

Seeing that Alun was cautious and hurriedly closed it for fear of running out of the "light" inside, Chen Xu was relieved.

Aaron hummed softly, kept trying, and even ran outside to illuminate the scene in the backyard of the restaurant with it.

I saw that half of the small courtyard was illuminated, and it was amazing, Zhang Gen and the others couldn't sleep, looking at this thing dumbfounded, the existence of this flashlight simply exceeded the limit of Tang people's imagination.

At this time, in the eyes of Zhang Gen and others, Chen Xu was like a devil, omnipotent, and it was simply terrifying.
