Following the fleet of the Chamber of Commerce into the dock, I saw that the lights of Liuhe Port were brilliant, not phosphorescent, nor the lantern candlelight of the city at night, but like the magic weapon brilliance, very bright.

A huge pillar of stone rises like a majestic mountain peak and reaches to the top of the huge cavern where the lake is located.

The base of the boulder pillar is a hill, and the brilliantly lit port buildings are all over the hillside, and even the boulder pillars have been carved out of layers of caves, almost extending to the top of the stone pillars, and the caves on the pillars are all bright lights, reflecting the majestic and lofty stone pillars, which is extremely magnificent.

Xu Yibing frowned and said: "Although this port looks brilliant and magnificent, it is shrouded in a thick evil atmosphere, and it is not a good place!"

Mr. Cicada Hua smiled: "Hehe, Miss Xu has good eyesight, but your so-called evil qi is not only harmless to the six poisonous spirits, but also helps them improve their cultivation, but the aura in their eyes is released during the operation of the light array." ”

Seeing that the ship was about to dock, he hurriedly took out a small glass bottle, poured out six pills, kept one for himself, and distributed the remaining five pills to Sima Chengzhen and his group of five: "Quickly take this medicine, you can improve your tolerance to this qi." ”

In fact, their body protection divine light had already lit up to resist the evil qi, and after taking the pill, they all gradually dimmed and converged.

Noticing that Mr. Cicada Flower didn't give Honggu pills, Feng Luqi said, "Sir, don't forget Honggu!"

Honggu smiled lightly: "We are not afraid of this kind of anger." ”

Mr. Cicada Hua said with a smile: "Yes, among the six poisons, the scorpion is the most able to tolerate this qi, but the mushroom spirit can withstand the dose of this qi, which is dozens or hundreds of times that of the scorpion!"

Feng Luqi said: "Then is this qi also helpful to the cultivation of the mushroom spirit?"

Honggu nodded and said, "Yes, as long as the upper dose is not exceeded, it will be beneficial and harmless." ”

While speaking, the boat has docked, seven people got off the boat, Mr. Cicada ordered the puppet crew to unload, but Zhu Aya came in a snake: "Leave it to my deputy to command, please follow me to the Chamber of Commerce." ”

Following Zhu Aya out of the dock, she saw many low-flying ships of different sizes shuttling back and forth on the way, which was not only a spectacle, but also a sign of the prosperity and liveliness of this port city.

These flying boats carry seven or eight people in small sizes, a dozen people in medium-sized ones, or a little cargo, and large ones carry dozens of people or full of cargo, similar to cargo ships sailing on the lake.

Flying ships are also often built in the blessed land, and Sima Chengzhen and his entourage are not uncommon to this, but the island suppresses flying spells, and these ships must find another way to fly.

As far as Sima Chengzhen and his entourage know so far, they either use the rotor to agitate the air to generate lift, or they use ultrasonic suspension technology.

Some of them can see from experience which means are used, while others are difficult to judge accurately, leading them to suspect that there are other illegal means of flying, so this is also a wonder for them.

Feng Luqi said: "Honggu, these flying boats are small and have rotors, I know that they fly by agitating the air, but the big ones don't have rotors, and they are not in the shape of musical instruments, I don't know how to fly with the help of big sounds, is it possible that on this island, in addition to these two ways, there are other means of flying?"

The big sound is the name of the fungus spirit for ultrasound, and the so-called "big sound Xisheng" in the Xuanmen "Tao Te Ching" is.

Honggu said: "There are actually many ways to fly without mana, such as using an air bag to hold the hot air, you can fly, because the hot air rises." Another example is to use an airbag to seal a lighter-than-air gas, which can also fly. However, the instruments that fly with the help of loud sounds are not necessarily musical instruments, right? Those large flying boats are usually equipped with several rows of small bells, small drums, or small chimes at the bottom, and they are vibrated with mana to produce a large sound, and the car can fly. It's just that some of the lowest cabins are not exposed. ”

Yu Yunluo said: "Use the air bag to hold the hot air...... Isn't that a Kong Ming lantern? But you say there's a gas that's lighter than air, so what is that?"

"Don't you people from the spirit world study physical properties very much?" Honggu said in surprise, "You should all know how to avoid water, right?" In fact, this spell uses mana to break down water and produce two kinds of gases, one can not only open the bubbles, isolate people and water, but also allow the people inside to breathe, and the other is used to push the bubbles to move in the water, and this gas is lighter than air, sealed in the air bag, you can fly. ”

Sima Chengzhen said: "The spirit world will not suppress any spells, as long as the mana is enough, you can make your wishes come true, naturally few people delve into the properties of things, only the spirit objects that can enhance the mana can cause people to explore and study." However, people in the mortal world, because it is difficult to obtain mana, so many people will delve into physical properties and invent machines to break through the limits of physical strength. As far as flight is concerned, mortals have also known how to use air and heat, the former such as kites and bamboo dragonflies, and the latter such as Kong Ming lanterns, but they only let the artifacts themselves fly, and have not yet seen the use of artifacts to carry people to fly. As for the loud sound and the air that is lighter than air, mortals have not yet learned to use it. ”

Honggu asked, "What are kites, bamboo dragonflies, and Kong Ming lanterns?"

Sima Chengzhen felt that Honggu should have never seen birds, so he pondered for a moment and said: "The kite is a tool that imitates the flight of bats, but the wings cannot move, they can only glide, and it is actually more troublesome to fly."

The bamboo dragonfly is a kind of rotor, but it is just a small toy, there is a small wooden stick attached to the rotor underneath, and a pinch of small wooden stick can drive the rotor to rotate and make the bamboo dragonfly fly, but unfortunately it can not last, and the manned flight is even more impossible.

Kong Ming lantern is a papier-mâché lantern that uses a papier-mâché lantern to cover the heat generated by the burning of the candle inside, and the flying utensils are also a gadget, which cannot carry people to fly at all. ”

Honggu seemed to understand: "Why don't they use mana to drive their wings and rotors? Why don't they use a material stronger than paper and make the lantern bigger, so that they can carry people?"

Sima Chengzhen smiled bitterly: "The aura in the mortal world is thin, it is difficult to obtain mana, and it is unlikely that a few people with mana will ponder these gadgets." ”

Honggu was not satisfied with the answer: "But what about Kong Ming lanterns? They don't need to drive anything by mana, as long as they make the lanterns bigger and stronger, they can carry people flying, can't they do it?"

Sima Chengzhen was speechless for a while, pondered for a moment, shook his head and smiled bitterly: "I am also very confused about this question, they clearly have the ability to make the lantern bigger and stronger, but no one does it, maybe there is, but I am lonely and unheard." ”

Honggu said disdainfully: "Hey, mortals are really stupid, no wonder there is a mortal word." ”

The Demon Sword suddenly said: "You mushroom spirits seem to boast of knowing the properties of things very well, in fact, I think it is also very ordinary, the civilization that really studies the properties of things, can completely use no mana, only machines can continue to drive artificial wings and rotors, and even big sounds can be generated only by machines." ”

"What nonsense are you talking about?" said to him, and he was disrespectful to Honggu.

"I'm not talking nonsense! I've been with you for a short time, and I haven't told you anything yet. "I am now called the Demon Sword because before you, I followed the legendary Irish poet and warrior Xiang Xiang.

But before following him, I also had many different names, and I followed many mysterious and powerful people, some of whom did not belong to the mortal and spiritual worlds.

The universe is vast, there are civilizations on many planets, and among the people I have followed, there is a plane traveler who has taken me to many planets and seen many different civilizations.

From the perspective of using energy, civilizations can be divided into three categories, engineering civilization, magical engineering civilization, and magical civilization.

The engineering civilization has studied physical properties and developed to the top, and can do all the things that magic can do with machines. It is likely that the mortal world will develop like this in the future.

Magical engineering civilizations study both magic and engineering, often using magic to power machines. The civilization of this island clearly belongs to this category.

As for the magical civilization, of course, it is the intensive study of magic, and the spiritual civilization is one of the examples.

However, this island not only suppresses flying spells, but also suppresses space spells, if I guess correctly, all races on this island, including mushroom spirits, should not have developed machines that can use the laws of space, right?"
