"Cola?
Harvey imitated Li Zixuan's pronunciation and read it out loud, realizing that it was indeed catchy.
Hence, he downed a few more glasses.
He only put down the glass beaker when half of the round bottom flask was gone.
To be honest, he was already conquered by this sweet drink.
Compared to coffee and milk, he had no resistance to this thing called coke.
Then, he looked at his brother Bruce Lee with burning eyes, his eyes filled with endless worship.
Bruce was only ten years old like him, but not only did he design a safety razor and blade,
but he also invented a drink called coke.
Harvey had personally witnessed Li Zixuan step by step mixing all kinds of mysterious liquids that he had no idea what they were used for. In the
end, they turned into a drink that he could not stop himself from drinking.
It felt like Li Zixuan was using magic.
It was too magical!
"How about preparing some coke for the Smith Farm barbecue party tonight, Bruce?”
Harvey suddenly said.
Because everyone had been working tirelessly and Harvey had dropped out of school, Old Smith had informed them yesterday that they were going to prepare a barbecue party at the farm.
He would invite the Li father and son and some nearby farm owners.
Therefore, the little fatty suddenly wanted to serve Coke as the drink for today's party.
"I should be able to make some more, but not too much!”
Li Zixuan thought for a moment and said.
"Can't we mass produce Coke?”
Harvey asked in disappointment.
"It's okay to make some here, but if you want to mass produce them, you need to buy equipment to modify them. After all, manual work and machinery are very different, so it can't be done in a short period of time!”
Li Zixuan shrugged, expressing his regret.
However, although he could not mass produce it for the time being, he would apply for a patent for it.
However, the patent only included the general ingredients of cola, not the core essence ingredients.
After all, even though the recipe for Coca-Cola had not been filed for a patent in the future, that was because it was difficult for anyone to develop the recipe for Coca-Cola.，
However, Li Zixuan was not sure if the doctor who invented Coke would continue to study it in the future.
So, just in case, he would apply for a patent for Coca-Cola and its main ingredient.
This way, even if someone wanted to produce it, they would need to obtain his authorization. Otherwise, they would have to wait for the patent to expire for 20 years.
However, Coca-Cola would probably have already taken root in the Eagle Jam Nation by then.
Therefore, Li Zixuan agreed to Harvey's request. He made some Coke and put it in a metal can.
It was night time.
In Smith Farm, Old Smith had already set up a barbecue grill outside the house in the evening and added charcoal fire.
Bottles of whiskey and homemade tequila were placed beside him.
The farm owners near San Francisco all rode their horses to meet the appointment.
There were no less than a hundred people present.
This showed Old Smith's prestige here.
When Li Shi brought Li Zixuan to the farm, the farm owners did not discriminate against them because they were Chinese.
They knew that the Li family and the Smith family had a good relationship, so they were very friendly to the Li family.
After the party started, a group of people gathered around the bonfire, drinking wine and eating barbecue.
Some of the ranchers sing with instruments that look like guitar, but are actually called banjos
. Moonlight
I bathe in the moonlight
and I'll fill your glass with raspberry wine brewed from affectionate legends
. Since we parted, I've been singing songs filled with cowboys 'tears
, I've written poems that can't be comforted, drinking milky rum
like a kite flying in the wind
... A song about cowboys sounded pretty good.
At this moment, the little fatty Harvey brought Li Zixuan along and took out the metal jar.
"Gentlemen living in the west, this is a drink I just invented. I wonder if you'd like to try it!”
Li Zixuan announced while standing beside the bonfire.
Hearing this, the group of cowboys who were drinking whiskey looked at Li Zixuan in a daze.
"How does the new drink compare to the wine of the chaos!？”
"Hehe, compared to wine, the only thing I'm interested in is women!”
"Kid from China, we don't want to drink any drinks. That's something women drink!”
The group of farm owners were talking among themselves, but none of them wanted to drink Coke.
In response, the little fatty, who wanted to shock these uncultured country bumpkin farm owners, immediately gave up.
"The coke invented by Bruce is the best drink in the world. Everyone will definitely feel good after drinking it!”
Hearing the little fatty's words, even Li Shi and Old Smith, who had already known about this, were a little surprised.
In fact, although they knew that Li Zixuan had invented something called Coke, they had never drunk it before.
However, they obviously didn't expect that the beverage named Coke would capture little fatty Harvey's heart and make him admire it so much.
It was called the best drink in the world.
Hence, not only were Li Shi and Old Smith interested, but even some farm owners who were familiar with the little fatty were also curious.
What exactly was this thing called Coke?
Seeing that someone's interest had been ignited, Li Zixuan and Harvey opened a five-liter can and poured out the bubbling brown liquid.
After personally pouring the wine glasses of some farm owners.
"
Please have a taste, gentlemen!" Li Zixuan said with a smile.”
Old Smith looked at the bubbling liquid in the glass and took a sip.
His eyes immediately lit up. The sweet and refreshing taste immediately cooled his fiery mouth after eating the roasted meat.
"Ha!" After putting down the cup, he even burped.
Like him, many farm owners who drank Coke felt that this drink was not bad. Although it could not be compared to whiskey,
it was indeed eye-catching as a drink.
"This kind of thing should be very suitable for children and women to use!”
a farm owner said.
Because of the low status of women in this era, all the farm owners did not bring their female companions to the party, so they did not know how women felt.
Even so, everyone present was very interested in this novel thing.
Wine could be drunk freely in the future, but cola was something that could not be found anywhere else.
As a result, the 5L cans of Coke were quickly emptied. Some of the farm owners were still not satisfied.
After this incident, the farm owners had a good impression of Li Zixuan and the Li family,
especially Li Zixuan, who was able to invent this drink. Moreover, according to Old Smith, even the recently popular safety razor was designed and invented by this little guy in front of them.
The farm owners all admired Li Zixuan very much.
After the party ended, they even told Li Zixuan that
if anyone dared to bully him, he should tell them and they would go over with shotguns to help.
Li Zixuan could only smile in response.
The next day, he woke up.
The daily check-in began.
"Ding... Today's sign-in is complete…Congratulations, the Host has obtained the oil coordinates of Little Boston, Isabella County, California!”
Immediately, Li Zixuan sat up on the bed like a spring.
(PS: New book, please collect it. Flowers, tickets. The new book is like a seedling. I hope to receive the care of all the readers. Thank you, everyone.) "Cola?
