There is a clock tower in Del Street in the slum of Sanshui City, this clock tower is the tallest and largest building in the whole of Del Street, and from the outside, this clock tower is nothing more than an ordinary building.

It had no doors, no other entrances or exits, only a ladder leading to the pointer that was rusty.

The hands of the clock had stopped a few years ago, but no one had thought of repairing it, and perhaps for the people of the slums, time was the only thing they could squander......

However, no one knows that under this old mottled, mossy and dilapidated building, there is a secret hidden by no one.

This is the Robin family's underground shelter, a bit rudimentary but not at all, and Robin calls it the "Underground Base".

Xue'er, the former water mage of the Snow Wolf Mercenary Squad, is now a subordinate of the four major guardians of the Eisen family, and under the careful guidance of the water guard, she has been upgraded from a junior mage when she first came to the family to an intermediate mage of the water system.

After half a year of life and study, Cher has also matured and stabilized, and this time, her mission is to escort Rosa with her brother Carl and teammate Keith.

Originally, Robin said that he would be responsible for Lothar's safety, and the patriarch Oak proposed to let the four guards divide into two teams to protect him, but Robin refused, saying that it was not necessary and that it was inconvenient to have too many people.

This once made Cher think that Robin was too arrogant and unreliable, but now, when they came to Robin's "underground base", Cher and the three of them had a completely changed impression of Robin......

Although it is underground, the Underground Base is a perfect place for them to live for a long time, as it not only has a huge labyrinth that spreads all over Del Street as a defense, but also has a complete and independent ecosystem.

Cher couldn't imagine that in the center of these passages, under the clock tower where they were now located, there was a fruit tree up to 10 meters high, and this fruit tree was full of spherical fruits, the small ones were the size of fists, and the largest ones were comparable to footballs.

And the most outrageous thing, this fruit tree is still bathed in sunlight, this ray of sunlight is full of warmth, she is sure that this is indeed the real sun, she can't figure out how these rays of sunlight came to the ground?

"This tree is called Apalo, and it's the main source of food here. ”

Robin walked past Cher, and when he came to the bottom of the tree, he cut the gray-brown bark with a dagger, and saw that milky white sap slowly flowed from the cracked place, and the sap seemed to be as thick as the latex of a rubber tree, and the sap solidified after a short time when it came into contact with the air.

Robin cut a small piece with a dagger and put it in his mouth and chewed it, then cut another piece and handed it to Cher, chewing and saying, "This is my favorite snack, sweet and sour, very chewy, you can taste it, but this thing is not digested, don't swallow it." ”

Cher's eyes flickered with adoration as she looked at Robin, in her eyes, Robin was so mysterious and wise that she couldn't guess, but she admired it.

"Ahem, well, I'm going to be shy if you keep looking at me like that. Robin was embarrassed to see Cher standing there distracted, not reaching out to take the juice he had handed over.

"Uh...... I'm sorry, Brother Robin, I'll try it......" Xue'er's face turned red, she hurriedly took the piece of thing and put it in her mouth and chewed it quickly, "Hmm?!It's sweet and sour, soft and glutinous, it's delicious, does this thing have a name?"

"No, huh...... Let's just call it 'Palo Snow Candy'. Looking at Cher, Robin came up with a name.

"Palo Snow Candy ......" Cher remembered the name deeply in her mind.

At this time, Robin reached out and shot out the flower bud cord hidden in the cuff, shooting down two football-sized spherical fruits on the tree, he took them and checked them in his hands, and said to Cher with a smile: "Let's go, these two ball-like fruits are our lunch today." ”

Xue'er's eyes widened, and she asked, "The fruit of this tree is so big, it's about the same as a coconut, and this can be eaten?"

"Absolutely, hehe. ”

It's time for lunch......

"This!this!this...... Is it bread?!" Carl let out an exclamation as he took a bite of Robin's freshly baked fruit slices.

"It's like bread, isn't it? Hehe, it tastes sweet and sour, soft and delicious, and very nutritious, like the grain grown in the field. Robin cut a few slices and handed them to Cher and Keys.

"We don't have any fruit trees like this here, do we? It is amazing that they can produce bread. The magician Keith was amazed.

"Well, we don't have it here, this is what I and the Aisen family want to come over, at that time I said to the patriarch of Aisen, is there a plant that is easy to survive, does not need to be cultivated and harvested every year, and can be harvested every year after planting, and it is rich in nutrients, the yield is high, and it is best to have green leaves, which can clean the air. ”

"Then Patriarch Eisen gave me the seed of the tree. Haha, I didn't know how to plant it originally, but fortunately Lothar came to help me cultivate it, and I heard Lothar say that this kind of tree can normally produce about 200 fruits a year when it grows up. ”

"But after Lothar's conditioning, the tree has multiplied its yield, and thanks to her, it has become the main source of food for my underground shelter. ”

Speaking of this, Robin looked at Rosa who was lying motionless on the bed in the other room, and he sighed and said, "But...... But now she is asleep, alas...... O sea heart...... When will you find the fruit of the sacred tree?"

Speaking of Rossa, everyone was silent......

Xue'er saw that everyone was silent and the atmosphere was awkward, so she quickly changed the topic: "By the way, Brother Robin, when you took me to see the Apalo tree just now, I wondered, you are dozens of meters deep underground, why is there sunlight shining in?"

"yes, is this magic, but why can't I feel any magic?" said the magician, Keith, who wondered.

Robin said as he ate the slices of the fruit of the Appalo tree, "Hehe, it's very simple, do you know the periscope?"

"You mean the reflection of light?" Keys immediately opened his mouth as he heard Robin speak of the periscope.

"Bingo! It's the same principle, it relies on mirrors to reflect sunlight in, and the top mirror I placed on the top of the clock tower, it can adjust the direction, and I don't use this sunlight to illuminate the Apalo tree. ”

"With sunlight, the Apalo tree can thrive underground, and it also helps clean the air. Robin opened a mechanism overhead, and Cher could see that there was a large mirror embedded in the wall, and the light in the mirror was very bright.

"You can do such a wonderful thing without the help of magic, Brother Robin, you are really amazing. Cher complimented sincerely.

At this moment, Cher simply worships Robin like a god!
