Video spoilers history, starting with the blitzkrieg on Poland

The new sky appeared amidst a cheerful tune.

At a crowded exhibition site.

A burly man weighing 180 pounds walked into the camera with a smile. He held a watermelon and put it on the ground.

He rubbed his hands again.

Carefully lift your foot and slowly step onto the watermelon.

The watermelon held the weight firmly and did not move at all.

Seeing this, the big man simply stood on it.

The crowd first held their breath, then burst into exclamations and applause.

The staff member picked up a fruit knife and gently cut open the hard melon skin.

In the lens.

The bright red flesh of the melon is instantly revealed, dripping with juice.

The host picked up a piece with his fork and took a big bite.

And Tianmu officially began to narrate:
【My dears! 】

[At a recent agricultural expo, watermelon farmers displayed a watermelon named WL21097.]

【This melon is not ordinary. 】

[It comes with hardcore skills! ]

[A 180-pound man stood on the melon, but it remained motionless and unharmed.]

[When you cut open the hard melon skin, you will find the flesh inside is crispy and sweet. It is a pleasant surprise when you take a bite. ]

[In fact, there are precedents for this kind of watermelon that is "hard on the outside but soft on the inside." ]

[Why is the agricultural industry so keen on cultivating hard-skinned melons? ]

[Will the skin of this golden melon become as thick as a wall? ]

[Why does the key watermelon have to be so strong? 】

[There is no need to apply a real bulletproof coating! ]

[First of all, this kind of watermelon has been improved mainly by increasing the toughness of the rind. ]

【As for the thickness, it didn’t increase too much. 】

[And scientists have made watermelons more resilient. ]

[Scientists are "tinkering" with watermelons in this way. To put it bluntly, they want us to enjoy eating watermelons more and make watermelon farmers' wallets fatter! ]

[For this, I specifically consulted Chen Chunxiu, a researcher at the Beijing Academy of Agricultural and Forestry Sciences.]

[Teacher Chen revealed that my country's annual watermelon production is as high as 6300 million tons, and has been ranked first in the world for more than 30 years! ]

【But there is some water behind these data. 】

[Because the seeds have poor disease resistance and some melon farmers do not plant in a standardized manner. ]

[In fact, about 15% of watermelons rot in the fields due to pests and diseases.]

[In addition, some varieties are not resistant to storage, and more than 20% of the fruit will be lost from picking to supermarket shelves.]

[If sales are not timely, a large number of watermelons will be unsold. ]

[After all, the watermelons we can actually eat are probably only half of the production! ]

[And every 1% reduction in the loss rate can generate an additional 3000 million yuan in revenue. ]

[The melon skin becomes stronger and is not easily damaged during transportation. The storage period is also extended from 7 days to 30 days, so we can naturally eat more melons! ]

【Teacher Chen also told me that whether the melon rind is firm or not is related to these three aspects.】

[One is the shape. Oval watermelons are naturally more durable than round ones;]

[The second is grafting, which combines watermelon with pumpkin and gourd to increase yield and resist disease, and also thicken the melon skin;]

【The third is variety, through hybrid breeding,】

[At present, Chinese researchers have found the gene on chromosome 10 of watermelon that controls the accumulation of lignin in the cell wall.]

【Through scientific breeding, the hardness of watermelon peel can be increased by more than 58%. 】

[Experimental data show that the hardness of the improved watermelon peel can reach 27 kg/cm17, far exceeding the kg/cm of ordinary watermelons.]

This technological breakthrough brings significant practical benefits:

[The fruit cracking rate during long-distance transportation has dropped from 10%-20% to less than 5%. ]

[The storage period at room temperature is also extended from 7 days to 30 days. 】

[The "iron-skinned watermelon" displayed at the Expo is a successful example of this genetic improvement technology. ]

……

Outside the sky.

Tang Dynasty.

As a veteran foodie, Emperor Xuanzong of Tang, Li Longji, had naturally eaten watermelon.

Although during the Tang Dynasty of Li Longji, watermelon had not yet been widely spread in the country.

But the watermelons that were tributed from the Uighurs were naturally given first to Li Longji and his men.

Looking at the fresh and delicious watermelon on the sky.

I thought back to the melon I ate.

Li Longji couldn't help but feel a little greedy.

"The watermelons on the canopy look really good."

"Compared to the melons I eat, this one should be much more delicious."

Next to Li Longji, Yang Yuhuan also wanted to eat the watermelon on the skylight.

Then Yang Yuhuan also remembered her favorite lychees.

"Your Majesty, look at this canopy. People in later generations have cultivated watermelons into varieties that are easy to transport and store."

“And the taste and appearance are also very good.”

"If only the lychees I like to eat could have a thick shell like watermelons, so they can be easily transported and won't go bad for 30 days."

"Then it will be much more convenient for us to eat lychees."

Li Longji nodded and said:

"Indeed."

"For fruits and vegetables, it is very important to significantly extend the shelf life and reduce damage during transportation."

"Like this watermelon on the canopy."

"I can even transport them directly to the front lines after large-scale planting."

"30 days is more than enough time for the soldiers on the front lines to eat watermelons."

"With stronger logistical support, the soldiers will fight more bravely." Tianmu continued.

【By the way, let’s talk about another topic about watermelon. 】

[In the past two years, there have been many hot searches about the high prices of watermelons in some countries. ]

[Are their breeders not working hard enough? ]

【Not really. 】

[Take the United States as an example. They mainly focus on cultivating high-quality watermelons. ]

[In order to facilitate long-distance transportation and export, we first developed a transportation-resistant variety with hard and crack-resistant skin. ]

【Although the quality is uniform. 】

[But this boutique route results in limited production and high prices. ]

[The United States still needs to import more than 90 tons of watermelon each year. ]

【China is taking the route of "large quantity and fullness", allowing 14 billion people to realize "freedom to eat melons" first! 】

【And don’t worry about loss. 】

【This is just a transitional phase, it’s all temporary.】

[In the past 10 years, scientists have been working to ensure production while improving quality. ]

[Now there are a variety of watermelons on the market, with white flesh, yellow flesh, red flesh, green skin, black skin, with seeds, and without seeds. All tastes can be satisfied! ]

[If you have a treasure, you will definitely tell me. 】

【I just love the thin-skinned hand-torn melon. 】

[The skin cracks with a slight pinch. ]

[It would be best if the watermelon rind didn’t even exist. ]

[Of course.]

[Our domestic watermelons also have a high-end market. ]

【Thin-skinned black beauty, special little phoenix, etc. 】

[But these melons are also expensive. Small Phoenix melons and Qilin melons are only five or six yuan per pound.]

[Many netizens said: They are only willing to buy one or half at a time. ]

[For melons like Sweet King, which cost only a few cents per pound, in major melon-producing provinces, people often buy a dozen at a time and take them home.]

[If we can lower the loss rate in the future, won’t our melons be amazing? ]

[Let’s imagine, maybe in the future there will be a “dream melon” with a skin as thin as paper and super durable in transportation? ]

[Of course, the price can be lowered further! ]

【Wait until then. 】

[In addition to meeting domestic demand. ]

[If someone is short of melons, we can still hesitate - should we keep them for ourselves to show off, or sell them to our neighbors? ]

When the video ended, comments started flying out.

"It turns out that the loss is as high as 15%, which is indeed a big loss."

《Durable in transportation and storage! Good! Buy! Eat it! 》

《As a spectator, I must give a thumbs up. 》

"No wonder I feel like it's getting harder and harder to tear the melon rind by hand in recent years."

"What if Huaqiang can't cut the melon open next time?"

《The Magic Melon that Prevents Strong Sons.》

"Are those boiled watermelon rinds also harder on the teeth?"

"Smecta is furious! The melon rind is fried and then can't be chewed..."

"Storage durability is the key, and it is very convenient for modern large-scale production and sales."

"I'm a little worried. Tomatoes are now more durable in storage, but the taste doesn't seem as good as before."

"Please lower the price of watermelon. I wanted to eat watermelon yesterday, but I went to the fruit store and saw it was 8 yuan per pound. I couldn't afford it."

"Now these are all greenhouse melons. If you think they are too expensive, I think they are too expensive too."

"When the watermelon season comes, I'll let you know what it means to eat a lot."

"Don't say anything, I'll be crazy about iced watermelon in a few days! It's perfect for quenching thirst!"

……

Outside the sky.

Han Dynasty.

Liu Che looked at the bright red melon flesh on the sky.

The fine grape wine sent as tribute from the Western Regions suddenly lost its flavor.

"This red flesh looks very thirst-quenching?"

"Why didn't Zhang Qian bring back such a magical object?"

"It seems that there are really a lot of good things in the Western Region."

"I'm afraid that the development of the resources of the Western Regions by our Han Dynasty is less than 10%."

"Once the Han Dynasty has completely taken control of the Western Regions, how many vegetables and fruits can they bring back from there? It's simply unimaginable!"

"As the great emperor of the Han Dynasty, I can also eat iced watermelon!"

And in the Ming Dynasty.

Zhu Yuanzhang saw these solid big watermelons on the sky.

He was also very happy.

Zhu Yuanzhang picked up a piece of watermelon and said while eating:
"Watermelon is a really good fruit. It quenches thirst in the summer."

"If it's iced watermelon, it tastes even better."

"When we were little, if we could eat a piece or half a watermelon in the summer."

"That's so sweet that it's almost dizzy."

Zhu Yuanzhang thought back to his childhood and began to talk endlessly about his story with watermelon.

Talking and talking.

Zhu Yuanzhang was also a bit youthful.

"Someone, add ice cubes to our watermelon!"

Zhu Biao, who was standing by, was so frightened that he quickly advised: "Father, please take care of your health!" (End of this chapter)
