Seeing that Gu Yun would not take advantage of the frame and would not give up, Bai Ko pushed his chin vigorously with both hands, preventing him from kissing him. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"I didn't comb my hair, I didn't brush my teeth, I didn't wash my face, you stay away from me."

Gu Yun was happy, grabbed Bai Ko's wrists with both hands and clasped them behind her back, bowed her head slightly, and the delicate kiss fell all over her face.

"What's the matter? It's not like I haven't seen you just get up~"

Gu Yun laughed and hugged the person tightly.

"I haven't seen you for so many days, I miss me, let me hold for a while."

Bai Qi fell into Gu Yun's arms, and his face was slightly red.

The two embraced each other quietly until they heard the gurgling sound in their stomachs and looked up at the window to see that it was already dark.

"Ah, the morning exercise time is wasted~" Bai Ko muttered softly.

"Go wash up first, I'll practice with you after breakfast, you can practice whatever you want~" Gu Yun's eyebrows danced, and at a glance, he knew that his mind was full of immodest things.

"You don't want to be with me yet."

"Why? You're going out? ”

"King Qing is coming."

"Huh?!" Gu Yun looked unhappy, "What is he doing here?" Why hasn't he left yet?! ”

"He's leaving, he's already packing his luggage, taking advantage of the crisp autumn weather and little rain to travel far."

"Do you want to come here before we leave?"

"The gift promised to him is ready, he will come to get it, and by the way, it is considered a good thing to invite him to dinner." Bai Ko smiled and touched Gu Yun's bulging cheeks, "You two are not allowed to fight." ”

"Did you send the gift to him directly to his house, and he came to get it on purpose? You're here to eat, right? ”

"It's something new, either he'll take it or I'll send it."

"Then he'll take it." Gu Yun pulled Bai Ko's hand down and put it on his lips to kiss it, his attitude changed so quickly, "Men should run more errands, they won't die of exhaustion anyway." ”

Bai Qiao chuckled, pushed Gu Yun out of the bedroom, closed the door, washed and changed.

Xiao Yezi walked into the hall at this time and asked Gu Yun if he could bring breakfast, everyone was in a hurry, there was a banquet for King Qing today, and there was still a lot of work to be done in the kitchen.

Hearing the word King Qing, Gu Yun couldn't help but twitch his skin, but fortunately, he was finally really leaving, but he didn't know what novel gifts Bai Qiao had made.

The girls set up the dining table and made breakfast, and Bai Ko just finished washing up and came out with her home clothes.

The two had breakfast, Gu Yun drank tea and watched Bai Ko take care of the housework, and arranged the preparation for entertaining King Qing.

The housekeeper sent the housekeeper to wait at the gate of the square where King Qing must pass, Bai Ko arranged the housework, went to the kitchen for a walk, took a shower when he came back, re-dressed his makeup, put on good clothes for hospitality, put on jewelry with inlaid treasures, and waited with Gu Yun in the main hall of the front yard, and when King Qing came, she happened to be accompanied by Gu Yun, and she went to cook vegetables.

More than half of the morning, King Qing's car arrived as scheduled, although the car was simple, but the entourage still occupied the street at the entrance of the white house, Bai Ko and Gu Yun joined hands to the gate to greet and invited King Qing in.

Seeing Gu Yun here, King Qing Gongheng seemed to have a smile on his face, Gu Yun looked calm, and even raised his chin slightly proudly.

Gong Heng turned his face, ignored this stupid boy, and talked and laughed with Bai Ko with a smile.

"I received your letter yesterday saying that the gift was ready, you see that I brought my own soldiers according to your request, what good things did you make for them only?"

"Two hundred flints lit in the wild, specially made, waterproof and moisture-proof."

"What's the difference between flint and what we originally used?"

"Make a necklace and hang it around the neck, lighter and smaller, rain and snow weather can also be used normally, the climate in the south is changeable, there are hot and rainy places, there are also cold and rainy places, and the flint made of pyrotechnic materials is more suitable for the harsh field environment, even if it falls in the stream and river, it can be used to dry the water."

Bai Ko nodded slightly to Xiao Yezi, Xiao Yezi turned around and took out several boxes from behind, including flint and velvet, she opened a box and held it in front of King Qing for him to look at carefully, Gu Yun opened the other boxes on the table by himself, took one and played with it in his hand.

The texture of the metal magnesium used by pyrotechnic craftsmen is not pure, and there are other impurities, but the magnesium rod known by Bai Ko itself is also a magnesium alloy made of rare earths, since it has been successfully inspected and accepted yesterday, Bai Ko is too lazy to care about what components of the magnesium powder used by pyrotechnic craftsmen contains, after all, it is enough to surprise that more than 200 magnesium rods can be made.

Gong Heng looked at it casually, anyway, when he needed to make a fire in the wild, he didn't bother to do it himself, he was surprised that it was actually made of pyrotechnic materials, isn't that easier to get than natural flint?

"Since you've praised it so well, and you've spent so much time making it specially customized, why don't you try it for me?"

"Your Highness, please."

Bai Ko got up and took the two men to the courtyard outside, Gong Heng called his own soldiers, and Xiao Yezi led the girl to take out all the magnesium rod boxes and velvet.

Two hundred magnesium rods, Bai Ko asked the soldiers to pick one at random, and she spread several piles of dry wood and velvet on the ground, personally demonstrated how to make a fire, and told them to pay attention to safety, using fireworks raw materials, so the fire temperature was very high at the moment of ignition, enough to melt the gold ring.

After seeing Bai Ko's technique, he tried a few more times and pondered a few times, and one by one he successfully lit a small fire, shouted that it was easy to use, and then hung the chain directly around his neck.

Gong Heng laughed, accepted the two hundred magnesium rods, and the three of them returned to the house to gossip, and the soldiers in the courtyard happily helped the girls clean up the scene.

"By the way, since this flint is made of pyrotechnic materials, doesn't that mean that it can be mass-produced in the future?"

"Yes, in fact, I have this intention, the pyrotechnic industry is fiercely competitive, the profit is too low, improve it and make something new, it can also help the pyrotechnic craftsmen to live a better life, just these two hundred I spent a lot of money, the profit is high, and the craftsmen involved can do it with heart." is familiar with King Qing, and Bai Ko speaks casually, without the self-title of a folk girl.

"Since it is artificially made, there is an upper limit to use, how long can a magnesium rod last?"

"I don't know, new things, it's estimated that there are hundreds to a thousand times or so, so small, there shouldn't be many times to use it."

"Well, it's not as good as flint, but it's important that this thing can be made at will."

"There are a lot of outsiders in the capital, and I thought that the merchants who often run around in the wild would be interested in this, and I am planning to do some trial sales in the future to see how the market reacts."

"I'm not as good as you in business, I specially brought carrier pigeons when I went out this time, and when I settle down in the south, I'll write to you, it costs a lot of money to open up the wasteland, and I will make a fortune with me."

"Your Highness only needs to open the passage, and at that time, I will ask Your Highness to take me rich."

"Okay, that's it, you are my partner, you helped me get rich in the early stage, and when I open the channel to take the southern sea and become the king of Zhennan, I will take you to make a fortune."

Gong Heng raised his palm, Bai Ko immediately pounced, and the two of them slapped their palms three times, and Gu Yun was a witness.
