For more than a week at the Giant Panda Breeding Research Base, Zhang Xu entered various materials into the computer during the day and studied transformation techniques with Li Shenzhou at night.

Under Li Shenzhou's detailed explanation and teaching, Zhang Xu quickly mastered the key points of the transformation technique.

After a week of studying, Zhang Xu successfully turned into a primordial beast, and an unregistered Animagus was added to Hogwarts School of Witchcraft and Wizardry.

In the next few days, Zhang Xu learned from Li Shenzhou the technique of speaking after changing the organ in the case of transformation.

At this point, Zhang Xu's study is over.

Li Shenzhou was only entrusted by Zhao Lao to teach Zhang Xu, not Zhang Xu's master, and the knowledge that belonged to his personal inheritance would not be taught. His task was completed after Zhang Xu successfully transformed and stepped into the threshold of transformation art. Then teach Zhang Xu to be able to speak when transforming, as well as some knowledge in transfiguration and transformation, such as the concept of permanent transfiguration, or teach Zhang Xu's father for the sake of being a comrade-in-arms who was born and died together. And now Zhang Xu's level is not enough, just like an undergraduate student going to study a doctoral course, not only can he not understand, but if he can't do it well, he will disturb the knowledge he has learned now.

After thanking Li Shenzhou, Zhang Xu left Rongcheng and went north.

More than 40 kilometers southwest of the Mogao Grottoes in Dunhuang, there is a huge complex of large buildings like a crystal palace.

The façade of the nearly two-hectare complex is almost entirely made of transparent glass panels, through which you can see a variety of plants and water systems such as artificial lakes and streams.

This is the first miniature artificial ecological circulation system in China - Guanghangong No. 1.

When Zhang Xu followed Zhao Lao to this place for the first time before going to France last summer, he was stunned. At that time, he was told that this was an artificial ecological circulation system research base established to establish a long-term human lunar base on the moon.

After visiting the base at that time, Zhang Xu wrote a paragraph in the message book of the base.

When Zhang Xu came again today, Zhang Xu saw that this paragraph was inlaid on the shadow wall of the reception hall - "I am looking up, above the moon, how many dreams are flying freely." ——Zhang Xu"

"Xiao Zhang, this paragraph you wrote embodies a positive spirit, which is very in line with the goals of our base, and it rhymes, it is catchy to read, and we all like it very much, so we decided to put it here." The director of the research base said to the embarrassed Zhang Xu.

This is the last stop of the exchange visit of the students from the European magic school in China, and Zhang Xu will meet them here.

At the meeting on the day he returned to China this summer, Zhang Xu learned about the places that students from Europe would visit during this exchange visit.

Except for the school, all the others are research institutes, factories, and enterprises that combine the magic side and the science side.

Not to mention the others, Snape's three views alone have been shattered several times during this time.

While Hogwarts' Potions class used only a few tools, such as scales and crucibles, Potions classes in Huaxia used burettes, pipettes, graduated cylinders, measuring cups, test tubes, flasks, evaporation dishes, jars, fine-mouthed bottles, gas washing bottles, funnels, separating funnels, condensers, beakers, iron frames, glass tubes, analytical balances, thermometers, and other instruments.

While Snape was still simmering potions in the cauldron, the pretreatment of medicinal materials, the extraction, separation and purification of the active ingredients of medicinal materials, and the preparation and packaging of potions in Huaxia were already standardized, mechanized and automated. Even if Snape is tired into a transformed Sirius, the yield will not be able to see the other party's heels.

Snape is knowledgeable, but it is precisely because of his knowledge of goods that he understands how big the gap between the two sides is. The trick I discovered back then, squeezing the sleepy beans with the side of a silver short knife will make the juice easier than slicing, is useless in front of the juicer.

When the wizards came to the No. 1 Guanghan Palace, their three views were already shattered and could no longer be broken.

The moon, something that you only get into in astronomy and divination classes, and you tell me that you have to run up to the house and start a farm, and you can play together.

Guanghangong No. 1 is modeled after tropical and subtropical ecosystems, with five ecosystems: tropical rainforest, savannah, ocean, swamp and desert, as well as two artificial ecosystems in residential areas and agricultural areas.

There are about 4,000 species from Asia, Oceania, Africa and North and South America, including molluscs, arthropods, insects, fish, amphibians, reptiles, birds, mammals and other animals, including about 3,000 species of plants such as plankton, mosses, ferns, gymnosperms and angiosperms, including about 1,000 species of microorganisms such as bacteria, slime molds, fungi and microalgae.

These are just the contents of the public information, in fact, there are hundreds of magical animals and magical plants in the first number of species in the Guanghan Palace. These magical creatures will work together with ordinary creatures to form a closed ecosystem.

At present, Guanghangong No. 1 is undergoing the final animal and plant growth test, recording the growth data of animals and plants in an open environment.

Half a year later, Guanghangong-1 will begin closed operation for a year, during which time six scientists will live in this closed system.

Zhang Xu and Furong walked together in the visiting student procession, listening to the staff's explanation.

Zhang Xu looked at the students at Hogwarts and Beauxbatons around him, and all of them were sometimes shocked and sometimes confused.

When he came last year, he rubbed Zhao Lao's light, and he listened to Zhao Lao when the staff reported to Zhao Lao. But at that time, the main structure had just been completed, and the construction of the ecosystem had just begun, and there were many things that were not mentioned in the report at the time.

Listening to the staff's explanation, Zhang Xu found that the slightly core content of the explanation had been removed, and it seemed that there was a strong sense of confidentiality.

When he first arrived here this morning, Zhang Xu heard the director of the base mention that the same type of experiment "Biosphere 2" in the United States had failed, and the proportion of oxygen and carbon dioxide in the atmosphere could not reach an equilibrium on its own.

This makes Guanghangong-1 learn the lessons of "Biosphere 2", and re-replenish and formulate corresponding plans in a short period of time to avoid repeating the mistakes of "Biosphere 2".

At the end of the tour, the students returned to Dunhuang for a day of rest, where they will be flown back to the UK and France the next day at Dunhuang Airport.

And Zhang Xu is going home with Furong.
