When Jiang Weizhai was immersed in studying chemistry at home, before he knew it, Qixi Festival had arrived.

Wu Erniang's family has completely settled down, all life has begun to get on track, and Wu Yang's family has begun to run around all day, contacting friends who used to have a good relationship.

And Wu Erniang was showing off flowers at home, complaining that Jiang Wei had left his family here and hadn't come for a long time.

Thinking of the Qixi Festival, Wu Erniang thought about it, maybe this is an opportunity, Wu Erniang has heard the reputation of Jiang Weixian's disciple for a long time.

For her, it doesn't matter whether the immortal disciple is true or not, what matters is his ability, and at present, their mother and daughter can be said to have been almost forced to a dead end by the martial brothers, and when she thought of this, a raging fire ignited in her heart. So, she boldly came to the Xu Mansion and handed over a letter to a servant, which was passed to Jiang Wei.

On the afternoon of Qixi Festival, perhaps because of Qixi Festival, Xu Hui and Xu Lu also had a group of little children who followed Ruoniang to find Jiang Wei.

"Brother, today's Qixi Festival, Ruoniang wants to eat chilled mung bean soup."

Jiang Wei glanced at Ruoniang, and lightly touched his finger on his little nose,

"At your point, my brother will give you something better."

A group of little kids were suddenly unhappy,

Thirteen-year-old Xu Qizhuang didn't believe it, "Is there anything better than chilled mung bean soup?" ”

5-year-old Xu Qitan also shouted,

"I don't believe it."

Xu Hui is also curious, in this hot summer, a bowl of chilled mung bean soup can be said to be an excellent delicacy, what is more suitable for summer than chilled mung bean soup?

Jiang Wei sat on the chair and thought to himself, with baking soda, the drink has opened the door to a new world since then, do you know?

"If you want to drink, you have to work. Qi Zhuang, you go get brown sugar. Lu Niang, you go and get white vinegar. ”

After giving the order, Jiang Wei took baking soda, twelve small glasses, and a wooden stopper. He also asked Ruoniang to bring a small half bucket of water and prepare saltpeter and put it in the water.

After the eldest cousin Xu Qizhuang and the little cousin Xu Lu came back, Jiang Wei smiled proudly,

"In a moment, the time will come for you to witness the miracle."

Ruoniang looked at the brown sugar and white vinegar with a confused face, indicating that she couldn't understand.

"Brother, what are you going to do? Do you make brown sugar water? Why use vinegar? ”

I saw Jiang Wei looking up at the sky, feeling that his mood was so complicated, he put the brown sugar into six glass bottles, poured water, stirred and melted.

So six cups of brown sugar water are reached.

Jiang Wei poured the baking soda into each of the six bottles, then picked up a small spoon and opened the vinegar jar.

"Now, the time has come to witness the miracle."

I saw that after a spoonful of vinegar was poured into the brown sugar water, a lot of foam appeared in an instant, Jiang Wei hurriedly plugged the mouth of the bottle with a wooden stopper, looking at the black liquid full of bubbles inside, feeling so nostalgic.

And Ruoniang, Xu Lu and 5-year-old Xu Qi Dan saw this scene and muttered one after another,

"The water is boiling, brother (cousin), the sugar water is boiling"

As the eldest cousin, Xu Qizhuang and cousin Xu Lu were also shocked and didn't know how to describe it.

A bottle of Coke, reached.

The eldest cousin, Xu Qizhuang, finally couldn't help but speak,

"Cousin, are you playing a trick? Why is the sugar water boiling instead of cooking? ”

Jiang Wei glanced at his eldest cousin, and said with a smile under Xu Hui's curious gaze,

"The sugar water is not boiling, it's just a chemical reaction. This white powder is called baking soda, and when white vinegar and baking soda are mixed together, a wonderful reaction occurs and a large amount of carbon dioxide is produced. ”

Xu Hui and the five of them were stunned when they heard this.

Jiang Wei smiled,

"Actually, it's a kind of knowledge, if you want to learn, I can teach you?"

Xu Qizhuang was happy in his heart,

"Is this rumored by the outside world, what about the immortal family's spells?"

Jiang Wei nodded,

"To be precise, it's the knowledge of the immortal family."

Five people watched fun, amazed. Six bottles in a row were quickly made with six bottles,

Jiang Wei smiled at the five of them,

"Put the bottle in the bucket, chill it, and you're ready to drink, it's absolutely delicious!"

Although Ruoniang couldn't understand it, she absolutely trusted her brother, and then picked up the bottle and put it in a bucket to chill.

Jiang Wei sighed,

"This is Coke for the first time in a thousand years, I don't know what it tastes like, so I'm looking forward to it."

Ruoniang asked curiously,

"Brother, that's Coke? Not brown sugar water? ”

"Of course not."

Jiang Wei smiled mysteriously,

"The black one is called Coke, and the one without color is it. It's a drink, if there's another fried chicken......"

Jiang Wei couldn't help but drool, well, there was baking soda, stir with flour, and then wrap the surface of the chicken in a thin layer, and the fried chicken is no problem. When to try it?

About ten minutes passed.

"Cousin, can you drink it?"

Xu Lu couldn't wait a little and muttered,

"Drink."

Jiang Wei first picked up a bottle of Coke and divided it among the five people, Xu Hui took the Coke expressionlessly,

Looking at the black inside, I thought of brown sugar again, and thought in my heart that it was nothing remarkable. But when the cork was opened, the "wave" ran out with a breath, Xu Hui was startled when he heard it, only to see many small bubbles coming out of the bottle, a little curious, what is the reaction of carbon? It's really not hot, and the feeling of ice comes from your hands.

Xu Lu brought the bottle to her lips, tilted her head slightly and took a small sip, the stimulation of carbonic acid, the strange taste, she had never drunk anything like this, it felt very fresh and very exciting.

Jiang Wei took a sip, although the taste was much worse than the cola in his previous life, but it had an internal taste. For a while, full of memories came to my heart, and for a while I thought of my parents in my previous life, I don't know if they were okay later?

Sighed, a little homesick. But Jiang Wei understands that he should never go back, fortunately, he still has a younger brother, and hopes that the second elder will not be too sad.

"Wow, brother, that's great, Coke is great."

Ruoniang jumped and jumped with joy, and this joyful voice dispelled a trace of shadow in his heart and warmed his heart.

"It's good to drink, but you can only drink one bottle a day at most, and you can't drink too much."

Ruoniang's small mouth immediately pouted,

"Brother, you can't do this."

Jiang Wei shook his head,

"Don't learn what I can say."

After the five of them finished drinking Coke, Jiang Wei drove them all away.

If the mother is not happy,

"Brother, today is the Qixi Festival, won't you celebrate the Qixi Festival with us?"

Jiang Wei shook his head,

"I have something to do today, so I'm not going."
