Since the promotion of saltpeter ice, the night in Chang'an is no longer as hot and dry as before.

And because they spend the whole day at home during the day, many women have eaten dinner, and when their husbands wash the dishes and clean up the house, they go outside and get together with other women in twos and threes to enjoy the cool and brag (chat).

Those women who don't have a family wander around, hoping to find a handsome guy or something, or go to the green building to linger......

But at this moment, a huge roar suddenly came, like a thunderous explosion, accompanied by a shock of air, and everyone was startled.

"What happened?"

"Is there thunder? Is it going to rain heavily? Heavy rain in summer is really rare in our Datang. ”

"No, it's not thunder, absolutely not!"

"Oh my God, look, what is that!"

The people were shocked, and with a burst of exclamations, they found that above the heavenly dome, an incomparably brilliant flower suddenly bloomed!

It is like a huge and sparkling rootless flower, blooming in the night sky, blooming with incomparable beauty and accompanied by a huge roar!

Although these 'rootless flowers' are short-lived, they appear one after another, as if dyeing the night sky in a colorful ......

These flowers are of different colors, but they are all colorful, the sound is so loud, the flowers are so bright, the whole Chang'an City is clearly visible!

"Oh my God, what the hell is this...... But why is it blooming in the sky, and there is such a violent sound, like a duel between masters!"

"It's so beautiful, such a big flower blooming in the sky, in the night sky...... Who made it?"

"That direction...... Is it the Imperial Palace?"

Many people rushed to the bottom of the 'flowers', but in the end, they stopped, looking longing and regret.

"Made in the palace?"

"It seems so, it's a shame that we can't see it up close, but it's good that the flowers are big and bright, and we can see them clearly even here......"

The people of the Tang Dynasty are very simple, and they have special respect for the empress.

After discovering that these flowers were blooming above the palace, they no longer crowded, but stood in place, looking up quietly, reluctant to lose even a penny of beauty.

For them, this is a 'flower' that they have never seen before, it can almost be said to be one of the most beautiful things in the world, and anyone can see that these flowers do not last, they are short-lived, and naturally no one wants to miss them.

Outside the palace, the ministers who had just left the palace and had not yet arrived home were even more shocked.

When there was a huge roar in the sky above, and suddenly there was colored light, and Zhao Liang was in the night sky, they were all startled, and even thought that there was an invasion of foreign enemies......

"Who dares to be presumptuous on my Tang Palace!" General Zhang Ru shouted angrily and pulled out his long knife......

"Could it be that a strong man sneaked in and wanted to assassinate His Majesty?" General Huo's face changed slightly, and he was about to take off into the air......

"What's going on here?" the national teacher was stunned and looked up at the sky.

Rumble!

Fortunately, the successive 'flowers' and roars made them understand that this was not an enemy attack, but a similar ...... The existence of ornamental objects?

"This ...... What the hell is going on?"

The six Shangshu gathered together, all of them looked confused, and they couldn't figure out the situation. In this situation, who can figure out what's going on?

......

On Yonghe Street, after the envoys of various countries and their sons and brothers left the palace, they were all jealous and depressed.

Almost all of them didn't have the heart to eat dinner, they were all hungry and sulking, but the sudden change made their faces change drastically, and some people even thought that Datang was crazy and wanted to kill them all here!

It wasn't until they came out to do some research and inquire that they found out that it wasn't like that......

"Great, it wasn't aimed at us, I thought Datang used some new type of weapon, and he wanted to wipe out all of us here......"

"That's a strange idea...... Datang is not crazy, how can he ...... us Wait, don't say it, Datang's brains are full of muscles, and there's really nothing that can't be done......"

A person wanted to laugh a few times, but suddenly he was startled into a cold sweat.

Mom sells criticism, the country of Datang can't use common sense at all, no matter how crazy and unreasonable things are, they can do it......

"It's okay, it's good that those guys didn't do it, but what is it, do you know?"

"It's a bit like the gunpowder of our Yan Kingdom, but ...... Wasn't gunpowder used to fight wars and open mountains and build roads......? Gunpowder is the secret of my Yan Kingdom, how can it be ......" The Yan State envoy's face changed greatly, and countless possibilities suddenly flashed in his mind.

At this moment, she couldn't wait to fly back to Yan Kingdom immediately and report the matter to the emperor.

"Sure enough, do you think it's like it?" Chen Guo's envoy frowned and said, "I thought so before, but I didn't dare to confirm it, after all, gunpowder has always been only available to you Yan Kingdom......"

"No, I can't wait any longer, I must leave immediately, this matter is very important, and the gunpowder must not flow to the Tang ......"

The envoy of the Yan Kingdom took a deep breath, and was about to take people to rush overnight, but he was driven back.

It's a curfew, where are you going? I'll go back!

The soldiers defending the city are very resolute, they want to leave?

And seeing them come back in a hurry, the envoys of various countries, including Chen Guo, looked very strange, and seemed to be smiling......

......

In the palace, except for Lin Zifan, almost everyone was stunned.

The empress, Tsing Yi and Ziyi, Spring, Summer, Autumn and Winter, Zhou Xiaoyan, etc., were all stunned by this sudden change, looking at the flowers blooming above the sky, all intoxicated by the indescribable beauty.

For a long time, for a long time, the beautiful and brilliant flowers finally stopped, and the roar fell silent, and the beauty that seemed to be a flash in the pan finally stopped after holding on for a while.

"It's ...... What's it?" the empress was stunned, but it was still difficult to recover from the shock, and asked Lin Zifan a little cutely.

Of course, the cute image is made up by Lin Zifan's own brain......

"Your Majesty, this is the second birthday gift prepared by the minister for Your Majesty, fireworks ......" Lin Zifan smiled indifferently.

It's not difficult to make gunpowder, but it's difficult to make fireworks, at least Lin Zifan doesn't have the ability, but this time it's rare that the system has a little conscience, and he gave a batch of fireworks, and all of them are that kind of large size, which is not only powerful, but also very beautiful, and is used to beep at this time...... No, it's best to congratulate the empress.

At the same time, it can be regarded as a celebration of himself and the empress, so what?

"Fireworks?" the empress blinked, not knowing what she was thinking.
