Chapter 491 Reflection

As soon as I heard that Cheng Ling was going to start another popular science lecture, the live broadcast room exploded.

Flowers, cakes, and milk tea kept coming.

Barrage.

[I just like the knowledge points that the elder sister can pick up at her fingertips! 】

[If Cheng Ling were my teacher, I would definitely fall in love with learning. 】

[While you are still farting about rainbows, I have already taken out my notepad. 】

[I really want to know one thing, eldest sister, you have so much weird knowledge in your head, doesn’t it feel heavy? 】

[Can you invite my Lingling to participate in the next season of "The Strongest Brain"? 】

[Hey, brother in front, once you tell me, I think it will definitely look good! 】

[Compared with brain power, she can’t do it! You idiot fans, these live broadcasts are all scripted, you don’t know how long she memorized them in advance! 】

[Yes, yes, everything you said is right. Where is the administrator? Get rid of these black men quickly! ! ! Roaring with arms akimbo——]

Just listen to Cheng Ling say clearly:

"If you go to the wild and encounter extreme situations - such as no clean drinking water, no sufficient food, and no safe shelter, then if you want to survive, you must trust the judgment of animals. They are very sensitive to nature. More suitable for survival in the wild than humans."

"For example, if you see a tree in the wild, it is full of fruits. Each fruit is clean and beautiful, and there is not a single worm hole. Then, you must not eat it. Fruits that even insects are unwilling to eat will inevitably has a problem."

【Ah ah ah! It’s really like this! There is a plant called Nandina, which produces fruits that look like red cherries, which are very attractive! In the past, there was an unknown foreign tourist in our village who picked it and ate it. After eating a handful, he lay on the ground, started convulsing and had difficulty breathing... then he fainted and the ambulance took him away! 】

【Solanum nigrum! The unripe green nightshades are beautiful, poisonous, and no bugs will eat them! But when it matures, it will attract a lot of insects to eat——]

【And Phytolacca! This is super scary! Looks like a muscat grape. Eating it can cause diarrhea in mild cases, and incontinence or coma in severe cases. 】

The barrage flashed rapidly.

Cheng Ling continued: "If you are thirsty, boldly choose a water source for small animals to quench your thirst. For example, birds, squirrels, deer... Frogs are not included. Many frogs are poisonous themselves and have strong resistance to toxicity. Therefore, they The water source that remains does not prove its safety.”

"There are water drops on the spider web, which means it's a sunny day -"

"It's safer near the big trees where the birds build their nests. There are usually no vicious animals like venomous snakes and birds of prey."

"If you are in a place with special geology that is prone to collapse, and if you see holes dug by moles, feel free to set up a tent here. The soil quality here must be very good, and houses will not collapse in the middle of the night..."

Cen Cen, a college student, loves outdoor sports and has always longed to go hiking one day, so he asked: "Sister, if we want to go camping or hiking, what kind of luggage should we choose?"

"What to pack when going hiking or camping is a science. It's hard to explain in a few words. It mainly depends on your destination. For example, deserts, wetlands, jungles...you need to prepare different things."

“But first you have to be clear and try to keep your luggage as minimal as possible.”

"Overly heavy luggage will consume your energy."

"The things you bring should be necessary and can serve multiple purposes."

"Like coins."

"You can put coins in your sock with dirt, compress it, and you've got an extra strong stick."

“Coins can also be used as money to buy things with local fellows.”

"Also, if you go out to look for something in the middle of the night and are afraid of getting lost, you can scatter coins along the road to mark it. This is much more effective than spreading crumbs -"

Bread crumbs?

Others looked confused.

Only He Jinyu clapped his hands: "Isn't this the story of the candy house in the Grimm's Fairy Tales?"

She looked at the confused expressions on everyone's faces and was a little surprised: "Haven't you heard of it?"

Everyone shook their heads.

He Jinyu said, "There was a woodcutter from a poor family. His wife fell ill but had no money for treatment, so she died. He left behind two children."

"The lumberjack soon remarried. The stepmother didn't like the two children and convinced the lumberjack to take the two children deep into the forest and throw them away."

"As a result, the plan was overheard by the child."

"The next day, the woodcutter put the two children in a backpack and gave them a piece of black bread."

"The two children were afraid that they would not be able to find their way home, so they secretly threw crumbs of bread in their father's basket to mark their way home."

"As a result, the crumbs were eaten by the birds. So the two children were still lost in the forest."

Sister Xia looked regretful: "But, that is money...it would be a pity to throw it away..."

Cheng Ling said with a smile: "Of course I won't throw it away. When we return, use a flashlight to shine on the road. The coins will reflect the light..."

Cheng Lingtong stayed.

reflection--

reflection!

Cheng Ling suddenly stood up from the chair of the cable car sightseeing car.

She finally knew why she remembered those two visitors!

Because, one of the two visitors appeared in the secret video tape!

Where did he appear?

The answer is - in the convex reflectors installed on the streets of Paris.
