Bookstores in the wizarding world often have magic arrays that control temperature and humidity, and the bookstores here are no exception. After an afternoon of cool breeze in Ryan and Hermione's bookstore, it was quickly half past three in the afternoon.

Luckily, Ryan and Hermione had each spent a few Galleons on several books, so that the clerk didn't glare at them as they smoked the air in the house.

Ryan went to the post office again with a large bag of things, and packed and sent away all the gifts he had picked up for his friends in the morning.

On the way to the docks, Ryan asked Hermione curiously, "Most of the books you bought are in Spanish, and one is in Portuguese." Are you sure you can really read it?"

"Well. Hermione smiled slightly, "Anyway, our books are read separately, so I can just ask you if I don't understand something." ”

In a joke, the two arrived at the docks, where Professor Sprout was already waiting. Judging by the smile on her face, she should have found a lot of good things in this town. By four o'clock in the afternoon, everyone had arrived. So, after counting the numbers, everyone boarded the boat back to school.

Under the influence of the ship's magic, the ship went up the river at a very high speed, occasionally lifting its hull slightly out of the water due to the waves. If you look at the river, you will see canoes jumping up and down the river like salmon that return every year.

It's just that this way of traveling is not very friendly to the passengers on the boat, and when they returned to the school dock, many of them walked off the boat with pale faces and weak legs, and even a Hufflepuff fourth-grade boy threw up holding the pillar as soon as he got off the boat, but fortunately Ryan pulled him from behind to prevent him from lying on the ground.

As the canoes docked one after another, the students who returned from shopping also brought life to the campus, laughing and showing off the harvest of the trip, while exchanging their feelings with their friends.

Ryan and the others are no exception, but unlike the boys, who clean up and solve their personal hygiene problems, the girls go back to the dormitory to take a shower. So in the common room of the carriage, there were only a few boys left chatting. From these classmates, Ryan was surprised to learn that their field lab would be collectively scheduled for the week before Christmas.

It seems that there is still enough time to make some preparations, after all, the things arranged by the shopkeeper today are a bit strange, which makes people feel very uncertain, and it is always right to prepare more in this case.

So when he went to bed that night, Ryan went to Uncle Nine again, and after talking with Uncle Nine, he learned that the overall situation in the world here had stopped deteriorating and began to slowly develop towards a benign one. Especially with the abundant supply of sunlight crystals, the cultivators finally regained the upper hand in the battle of demons, and the abundance of cultivation resources also allowed the various sects to finally open the mountain gate to recruit new disciples, and the status of the ninth uncle in the Maoshan sect also rose.

Last time before Ryan left, Uncle Nine had asked Ryan if he could show them what the spells learned in the Western sect were, so this time Ryan came here with all the translated textbooks of Hogwarts and Castro Bruscher, plus a whole copy of the explanations and uses of ancient Norse Runes. Because it takes a lot of effort to translate these things, Ryan hasn't been able to get the finished product until now.

When handing over these books to Uncle Nine, Ryan was curious and asked him why he wanted to understand this kind of transcendent power that was not a system at all. The ninth uncle replied solemnly that the stones of his mountain can attack jade. He would ask the messenger to bring the books back to Maoshan to see what kind of knowledge he could draw from them.

Sure enough, always maintaining a humble heart and living to learn is the mentality that a true cultivator should have. Thinking of this, Ryan's pride in his heart after obtaining the thunder law also dissipated.

For the next two or three days, Ryan stayed in Yizhuang to ask Uncle Nine about his cultivation problems, and it was not until he solved all the problems he had encountered recently that Ryan said goodbye to Uncle Nine and returned to the Wanjie Grocery Store.

As soon as he returned to the Wanjie Grocery Store, Ryan received a message from the two worlds of Plants vs. Zombies and Fallout World, informing Ryan that they had prepared the exchange items they had discussed last time.

So Ryan took advantage of the opportunity he happened to be in the grocery store of the Ten Thousand Worlds to help the two worlds complete the deal: give the newly cultivated calendula that can absorb metal in a directional way to the Fallout World, accelerate the recovery of the ruins of the Fallout World, and at the same time hand over a batch of mechanical and electronic products from the Fallout World to the Plants vs. Zombies World, which is temporarily unable to produce in large quantities, but is in urgent need of these things due to the increase in population.

After another busy day, Ryan finally got all the chores done and went back to his dorm bed. This busyness made Ryan feel a little exhausted, but it was not all without gain: he felt that he had a lot more merit in him.

At this time, Ryan was really a little envious of other people's systems, and after doing something, he had all the strength and resources. It's not like he is tired and busy for half a day to get benefits, and it feels like his system is the same as a fake.

After muttering for a while, lying on the bed, Ryan was pleasantly surprised to find that some of the cultivation thresholds that he had encountered before that would take three or four months to solve were estimated to be completely solved this week under the guidance of Uncle Jiu, which meant that his strength would have a small improvement this week.

It seems that sometimes it is not enough to bury one's head alone and strive bravely, but also to be good at using all the forces that can be used, and it is really a waste to have such a teacher as Uncle Nine here, but it is really a waste not to ask when encountering difficulties in practice.

After summarizing the gains and lessons learned this time, the tired Ryan quickly fell asleep.

When Ryan woke up the next morning, he found a pile of presents piled up at his feet. It occurred to Ryan that this was the end of his second month in South America, and that Halloween was supposed to be tomorrow, and that these gifts were probably mailed in advance by friends in England, after all, transatlantic owl letters were sometimes not on time.

Because Castro Brus is deep in the Amazon rainforest, the temperature is above 25°C all year round, and the surrounding plants are evergreen all year round, unlike Hogwarts, when the sky is already snowflakes. Coupled with the heavy workload of schoolwork during exchange learning, Ryan felt that there was a lack of Halloween atmosphere this year, and it wasn't until he saw the pile of gifts this morning that he really felt that Halloween was coming.

This year's Halloween gifts weren't much different from previous years, the only thing worth noting was that the Weasley twins gave them a lot of candy and small treats, which were marked with large floral letters indicating that it was a prototype. It seems that after getting the data from Ryan's last time, the research of the twins has taken a big step forward.

Thinking of this, Ryan sent this pile of things to the Fallout World, where there were enough people and equipment to analyze the results of eating these things.

After all this was done, Ryan and everyone went to the auditorium for breakfast after washing up.
