What is the point of studying the stars and studying astronomy?

He knew that time, direction, and calendar needed to rely on astronomical research, which meant that the study of astronomy would help historical records, and the summary of solar terms through the calendar would be beneficial to agricultural work.

But what's the point?

Liszt touched his chin and squinted his eyes to think quickly: "Do you want me to carry the set of the twelve zodiac signs and rely on the constellations to study personality, fortune, and love matching?" This kind of "knowledge" seems to be of little significance except for hooking up with little girls.

But it soon occurred to him that there was a big role to play.

Zhengse said to Ake: "Don't think that it is useless to study astronomy, in fact, astronomy is likely to be of great use, I don't know if you still remember the legend about the Moon Empire, the legend says that the Moon Empire has a teleportation array to the moon, do you think that if you don't study astronomy, you can build such a teleportation array?"

"Huh?"

Ah Ke was really shocked: "My brother is very reasonable, without astronomical guidance, there is no way for humans to go to the moon. Although I don't know if the Moon Empire's teleportation array is true or not, if we live on a planet, the moon, as a planet, may also live with life. ”

"That's right. Liszt nodded faintly, believing his own rhetoric.

Many legends have been proven to be true, so the Moon Empire's teleportation array is not fake. If there really is a teleportation array that can land on the moon, he will definitely set foot on the teleportation array himself one day in the future and go to the moon to see what kind of scenery it is.

In fact, the mage tower of the territory, under the auspices of Chrissy, has been studying the magic circle of communication, using the magic net as the foundation to exchange information.

If the research on the transmission array is successful, it may be possible to further study the transmission array that can transmit objects on this basis.

Of course, the best way is to dig up some ruins and directly get the Moon Empire's teleportation array technology, and at that time, I'm afraid the distance is no longer a limit.

Anyway, the teaching of star-gazing has officially begun.

Taking out the telescope, Liszt motioned to Acker how to observe the celestial bodies—he had used the telescope to look at the sky since the invention of the telescope, so he had experience. However, due to the accuracy of the telescope itself, astronomical observation is difficult, not to mention that judging the trajectory of celestial objects involves complex calculations.

He didn't know anything about it.

After all, his math is quite poor, addition, subtraction, multiplication and division are quite good, but nothing else is good.

"Brother, since the telescope uses the principle of concave-convex mirrors, can Ake also make a telescope by directly controlling the water?"

"Well, it's not impossible, but it's not enough to simply superimpose the lenses, you also need the lens barrel to protect the light source. ”

"So what about this?" Ah Ke danced casually, and countless streams of water converged in front of her, and then the water quickly formed a cylindrical shape, which became a dark frosted surface that was opaque through a special arrangement, and two concave and convex mirrors composed of water streams were directly embedded in the lens tube.

So a telescope was made.

"Brother, the telescope made by Ake can see the stars in the sky!"

"Hmm. Liszt was a little envious of Ake's ability, this hand water control ability is really strong, "Yes, yes, you have mastered the specific principle, so let's continue to try to adjust the thickness of the concave-convex lens and the position combination between the lens barrel and the objective lens to find the most suitable observation factor." ”

He quickly lost interest in teaching Arker how to look at the stars, and allowed Arker to carefully adjust the telescope she had made with water.

He was lying on the body of the light emerald dragon, not knowing what he was thinking.

Dragon Douqi cheats, light emerald mines, mutated alder trees, surnames and country names, material assistance, title changes, Eagle Kingdom reactions, and countless other thoughts flickered in his mind.

The night was getting deeper, and before I knew it, I had fallen asleep.

......

Before dawn the next day, Liszt had already woken up.

I found that Ake had somehow gotten into his arms and slept with him in an intimate way, his petite body was a little cool, and the frost of early winter was condensed on his armor and Ake's magic cloak - he forgot to open the tent last night, and he didn't take out the Thermostatic Orb.

Fortunately, both he and Ake are strong people with physiques far beyond ordinary people, and this cold is nothing.

Ark slept very lightly, and the subtle movements of Liszt's body when he woke up had already awakened her. Stretching his waist, he left Liszt's body, said hello, and went to take out his toiletries and clean up. Liszt also rolled over and jumped off the light emerald dragon.

Wash your face and brush your teeth, and deal with it simply.

He used his magic eye to observe the alder forest, and immediately found an abnormality. The entire alder forest was filled with a light green glow, the same as the magical light of the light emerald dragon. But if you look closely, you'll notice a subtle difference.

The light emerald dragon's magical glow is more condensed, while the alder wood's magical glow is lighter.

He broke off a leaf, felt it slightly, and immediately found that the magic light of the alder tree was only a low demon, which was different in nature from the high demon that the light emerald dragon had escaped.

"So these alders have become potions?"

If so, it can be regarded as a good harvest, and the magic of the dragon can be infected with potions. However, he found several alders with a more intense glow, all of which were next to the body of the light emerald dragon. The trunks, branches, and leaves of these alders show signs of transparency.

Buckle off a piece of bark, play with it carefully, and quickly see the change: "It's as if the alder tree is not gradually changing towards potions, but towards stones...... Or is it a crystal change?"

Through the detection of the Magic Eye, half of the leaves have become real crystals, and the remaining leaves are only partially crystallized, and there is still magic slowly accumulating.

"Ake came over and took a look. ”

"It's coming. ”

After Ah Ke saw it, he was also very surprised: "Brother, these alders have grown into real crystals, look at this leaf, there is no difference between them and crystals." ”

Liszt said directly: "You carefully compare the crystal and the blade to see what the difference is. ”

"Okay. ”

Telling Aker to compare, Liszt himself continued to observe the entire alder forest, and gradually found a sign that the closer to the light emerald dragon, the higher the degree of crystallization of the alder, the thicker the trunk of the adult alder, and the more mature the leaves, the first to crystallize.

"It seems that when it matures, it begins to crystallize, and the immature part continues to grow...... "He concluded in an hour that the alder has mutated into a "crystal alder" - a alder that can grow into crystal, and when the tree matures, it will crystallize directly.

On the back of the crystallized leaves, there are rings of red bands, like the "seeds" of the alder tree, which are not crystallized.

On the contrary, if you wipe it with your hand, you can see many tiny seeds scattered into the air.

Each tiny seed flew in all directions with a faint, barely visible magical glow.

He couldn't help but call out the smoke mission.

"Complete the quest and be rewarded with a large slice of Crystal Alder. ”
