Chapter 70: Ah, the sea!

　　 "A big lake? How far is it?" Chen Fan asked.
　　 Wu Lei made a roll in the sky, Chen Fan understood, it took a day to walk.
　　 Chen Fan thought for a while and said, "Then this westward expedition will end at the lake. Xiaowu will lead the way. We will try to rush to the lake to sleep overnight before dark, and then go home tomorrow."
　　 "Yeah! I can finally go home!" Xiao Youyou cheered and said, although she was very happy to go out to play, she never stayed at home comfortably.
　　 "Ang!" Wu Lei immediately flew low in front of him with a dragon chant, scaring away all the beasts and monsters along the way.
　　Chen Fan took Xiaoyouyou and leaped vertically on the ground, striding hundreds of meters in one step.
　　 "Uncle Xiong, why don't we let Xiaowu take us directly to the lake? The scenery along the way is raining, and it's nothing good!"
　　 "If you are not afraid of being struck by lightning, you can let Xiaowu carry you to fly."
　　 rumbling rumbling!
　　 "Well, actually walking in the rain is pretty good."
　　 At dusk, the sky is getting darker. The rain weakened, hanging like a silk like mist between the sky and the earth.
　　 Wulei hovered and rolled in front of him. Chen Fan knew that the big lake was right in front of him. He took Xiao Youyou to speed up and climbed up a mountain, but there was a heavy fog in front of him, and he could only feel a cool breeze.
　　 Xiaoyouyou took a breath in the wind, and immediately covered his mouth and frowned, "What is the smell of Uncle Xiong? It smells so bad, why does it smell like dead fish?"
Chen Fan also smelled it, raised his eyebrows, and said casually: "It may be that the fish and shrimps in the lake died on the shore." As he speeded up, he jumped down the hill into the dense fog, and the grass under his feet was gradually replaced by the beach. Then I heard the sound of waves coming.
　　 Chen Fan smiled and said to Xiao Youyou: "How about Uncle Xiong giving you a big surprise?"
　　 "What's the big surprise?" Xiao Youyou asked, raising her head.
　　 Chen Fan mysteriously said: "You close your eyes, and then open them when I ask you to open them."
　　 "Okay." Xiao Youyou didn't think too much, closed her eyes obediently and was led by Chen Fan.
　　 After walking for about a few hundred steps, the wind became louder and the waves became louder. Xiao Youyou couldn't help asking: "Where is Uncle Xiong's surprise?"
　　 Chen Fan smiled and said, "You can open your eyes."
　　 Xiaoyouyou carefully squinted his eyes, then suddenly widened, stunned and exclaimed: "Wow!!! This lake is really big!"
　　 Chen Fan smiled and said, "Silly girl, this is not a lake, but the sea!"
　　 "The sea?!!!" Xiao Youyou was shocked, and said excitedly: "Uncle Xiong, is this the sea in the book?"
　　 "That's right." Chen Fan nodded, then stooped to pick up a conch from the beach and blew a breath, then put it in her ear: "Listen, the sound of the sea."
　　 "Wow! It's really the sea!" Xiaoyouyou immediately danced with excitement, jumping around on the beach: "I really see the sea!"
　　 Chen Fan looked at the vast and boundless blue sea, and he was also in a good mood, because he finally found the salt he dreamed of.
　　 "Uncle Xiong, look at I found so many beautiful stones!"
　　 "These are shells." Chen Fan smiled.
　　 "Oh, these are shells!" Xiao Youyou picked the two biggest pieces to stick on her chest, and raised her head and said: "Uncle Xiong, do I look like a murloc princess now?"
　　 Chen Fan could not laugh or cry for a while: "You are much cuter than the Murloc Princess."
　　 "Hee hee!" Xiao Youyou looked smug, turned around and ran to the sea and cheered: "I'm coming to the sea!"
　　 "Hey, watch out for the waves..."
　　HuWow!
　　 A wave shot the little girl directly back on the beach...
　　 "Bah, baah!" The little yoyo who became a squirrel immediately ran back, sticking out his tongue and exclaiming: "Uncle Xiong, this sea is so bitter and astringent! Pooh!"
　　 Chen Fan shook his head and laughed, and quickly handed her the water bag.
　　 "Sea water contains a lot of salt, so how can you drink a big sip without being choked?"
"Gululu, pooh!" Xiaoyouyou rinsed her mouth several times before removing the odor from her mouth, stomping and complaining: "Uncle Xiong, your story must be fabricated. How ugly is the sea? The fish princess stays in the sea. Li was dead soon!"
　　 Chen Fan laughed and said, "That's because we are terrestrial creatures. The murloc princesses are marine creatures, and they have already adapted to the saltiness of the sea."
　　 "Uncle Bear, is there any difference between this terrestrial creature and marine creature?" Xiaoyouyou immediately turned into a curious baby and asked.
"It's a long story. It starts from the origin of life...that is when the ancient father made the world..." While talking about the origin of life, Chen Fan searched for a winded in the woodland of the coastline. Make a campsite.
　　 First cut logs to build a simple shed, then cover it with leaves to block the rain, then surround a firepit with stones, and light a bonfire to dissipate the chill and water vapor.
　　 Chen Fan sat in front of the bonfire, roasting meat while telling the ancient origin of life.
　　 Xiaoyouyou and Wu Lei were enthusiastic, as if they had been opened to a new world.
　　 "I didn't expect my ancestors to come from the sea." Xiao Youyou touched her cheek subconsciously and wondered: "Uncle Bear, then why don't we have gills?"
"It's degenerated." Chen Fan explained: "The gills of fish are used to breathe in the water, but our ancestors can't breathe with their gills after they landed on the mainland~EbookFREE.me~ so our gills degenerate. Yes, but we have evolved lungs that can breathe on land. This is the use of advancement and retreat..."
Chen Fan shook his head and did not continue to explain, because the scientific community has proved that the use of advanced and abolished views is wrong. Biological evolution is completely derived from genetic mutations and natural selection is used to screen out those genes that are more suitable for the environment, and then continue to accumulate to produce evolution. And this process may take millions of years.
　　 Chen Fan looked at Xiao Youyou who was full of curiosity, and sighed that this world was no longer the world he knew well. Some magical things could no longer be explained by science.
　　 such as Wu Lei who is lying on the edge of the campfire and breathing out flames...
　　 "Uncle Bear, the water is boiling."
　　 "It's okay, let's burn for a while."
　　 "Uncle Xiong, why do you want to boil two pots of water?"
　　 "One pot is for drinking, the other is for boiling salt."
　　 Chen Fan directly picked up a hot coal and threw it into the tossing pot, splashing boiling water.
　　 Soon the sea water in the pot was boiled dry, and many white crystals precipitated on the wall of the pot.
　　 When the last bit of water was evaporated, Chen Fan took out the charcoal block covered with gray powder and discarded it directly, then scraped a little white particle from the pot wall and put it on the tip of his tongue to taste.
　　 The salty taste is slightly bitter and astringent, with a little fishy smell.
　　 This is actually coarse salt. It is generally used as industrial salt and cannot be eaten directly. It needs to be further processed into fine salt before it can be eaten.
　　 But Chen Fan didn't care too much. After all, there is no industrial pollution in this world. Naturally, there is no problem of excessive heavy metals in the sea. Besides, with his current physique, even if he eats coarse salt, he can't eat anything wrong. It's just that the taste of this coarse salt is so bad that it can't be accepted by his picky tongue.
