In late October, the weather is getting colder by the day.

After dinner, and after chatting and boasting with Mrs. Muller, Colin went to Tessa's room.

One of my experiments on the "wind core collision" still lacks several valuable materials and needs to be purchased.

At first, he always went to the teacher to reach out, but after a few times, he realized that the financial power of the Mage Tower was actually controlled by the senior sister, and the teacher was afraid that he didn't even know how much money he had.

After knocking on the door a few times, Colin realized that there was no one in the room, and he quickly jumped down from the twenty-third floor, out of the Mage Tower, and after walking a little south, he saw his sister Tessa in a garden.

This garden was planted by Tessa herself. Anyway, since Colin came to the Mage Tower, he has almost never seen his senior sister studying or meditating, either in charge of housekeeping, or writing and settling accounts, and whenever he has free time, he will run to this garden to work, which is considered self-cultivation.

……

Inside the garden.

Tessa is crouching on the ground to loosen soil for a few potted plants.

Colin followed, touching the leaves, touching the fruits, and constantly touching the flowers and grass.

After a while, I didn't feel like it was enough, so I brought my own hoe and shovel and helped to work together.

However, after all, his ancestors were a small nobleman, and although he had been down for a long time, he had never done farm work. Either hoe the plants by the roots, or accidentally step on the flowers of the senior sister when retreating, and the chickens and dogs jump for a while.

"Senior brother, don't make a mess, just watch from the side."

In desperation, Tessa confiscated Colin's farming tools.

Colin stepped aside.

Tessa saw him on the ridge of the field, and he didn't know how to put his hands and feet, so she couldn't help but laugh, and picked up a shower made of bamboo tubes, and said:

"If you really want to help, just water it."

"I will."

Originally, it was to cultivate sentiment, and it was not interesting to use magic to water it.

Colin rushed to the next tank with the shower and filled it with water.

"Why did you come back so early today?" Tessa leaned over to a pale yellow flower and sniffed it, chatting casually.

"I want to take a break once in a while." Colin ran back with the shower.

"Speaking of rest, the day after tomorrow is the Fire Festival, do you have any arrangements?"

"Hiding in the mage tower for experiments, count?"

"Of course not."

Tessa gave him a blank look and said, "You've studied too hard, so go out and relax on the day of the festival." ”

"Hmm."

Colin thought that he hadn't gone to Roy and the others for a long time, and he was also a little moved.

The Fire Worship Festival is a common festival throughout the Southern Continent, and it is said to be related to a strange celestial phenomenon in a certain period of ancient times, and even the orcs on the Plain of Wind Whisper will light as many bonfires as possible on this day to celebrate.

"It's said that this year's Fire Festival, His Excellency Harris will perform magical fireworks in the central square of the Canal District, so don't miss it," Tessa said. ”

"Then we really have to see."

It is a rare opportunity to let Harris, a serious and old-fashioned fire magician, do a fireworks show, and it would be a pity not to watch it.

Colin walked around the ridges with a shower, swaying wantonly.

Watering is fun.

Watching my sister plant flowers is also a pleasure.

Colin cherishes this short but beautiful time.

"By the way, the teacher asked me to convey one thing to you." Tessa stood up.

"What's the matter?" Colin wondered.

"The ambassador of the Principality of Gilman went to the palace and met His Majesty, saying that he hoped to purchase a photograph."

"Huh?"

Colin didn't expect to hang these guys and dry things out.

"You also know that Your Majesty needs the Western Continent to contain the Oshik Empire, so for countries like Gilman, it has always been to win over and make friends."

Tessa changed a small mini shovel and continued: "But this matter is too important, and Your Majesty has personally asked the teacher's opinion. ”

"What's the teacher's opinion?" Colin asked.

"The teacher's opinion is that you make your own decision." Tessa smiled: "But you still have to find a time to meet Ambassador Gilman as soon as possible, whether you agree or not, give people a word of accuracy, don't embarrass Your Majesty." ”

"I see." Colin nodded.

"Anyway, are you going to sell the camera?" Tessa asked curiously.

Colin smiled: "If others want to buy it, I may not be willing to sell it, but the Principality of Gilman, even if they don't say it, I will sell it to them." ”

"Why? Aren't you afraid that they will crack the key technology? Tessa was a little worried.

"There will always be risks in doing business." Colin smiled: "What's more, if they want to crack the current photographic machine, I'm afraid they will have to spend a little more effort." ”

"It's good if you're sure." Tessa nodded, and then asked, "But why is it only sold to Gilman?" ”

"Because they're the only ones who have what I want."

……

Seeing Colin's posture of planning to turn the garden into a lake, Tessa had no choice but to end the farm work early and walked back with the unfinished little brother.

She carried a small bamboo basket full of flower petals in one hand, and the other hand was still tucked into her sleeve.

Colin was curious: "Senior sister, what is the use of these petals?" ”

Tessa reached out and picked a few times in the bamboo basket and said, "Pick some good ones to make creams, and spread the rest in the flower pots on my balcony as fertilizer." ”

"So exquisite?"

Colin thought that sometimes he would come back late, and he would relieve himself in the grass next to the mage's tower. Later, the flowers and plants in that place grew particularly luxuriantly, so it can be seen that fertilizer should have the appearance of fertilizer, and the petals are definitely not as effective as shhh

……

……

The ten-day deadline was fast approaching.

When Colin entered the library's private room again, he saw Wald, who had sunken eyes and was extremely depressed.

"Mr. Wald, what do you think?" Colin sat down on the couch across from him.

Wald was in a trance, and it took him a long time to react to Colin's arrival.

"Mr. Wayne......"

"Looks like you've read all 32 books?"

"Yes." He nodded with difficulty.

"Do you feel anything?" Colin asked.

Wald was silent for a long time, and then suddenly sighed: "Mr. Vane, it seems that I don't need to trouble you anymore. ”

"Oh?"

"I was wrong, Schiller Moura was wrong, it turns out that I have been running on the wrong path all along, and the faster I run, the farther I am from the goal."

Wald laughed miserably: "I don't need to go to the designer of the gramograph anymore, Schiller Mora's idea is completely wrong, although I don't know how the designer made the phonograph, but it is clear that the same technology cannot solve the problem of the 'gramophone'." ”

After hearing this, Colin leaned back against the sofa, very satisfied.

Wald was a genius.

Although he didn't know anything about space magic, it was not easy to decisively eliminate the wrong answers with just ten days of study.

Sometimes, identifying a path is not feasible, and even more difficult than finding a viable one.

"It's not too late to understand, Mr. Wald."

"No, I've wasted too much time on it, and it's been in vain, maybe I'm not fit for research at all." Wald's face became extremely painful.

"Are you going to give up?"

"Maybe." Wald was confused.

"So, what if I say, I can solve the problem of frequency jumping?" Colin crossed his fingers and asked calmly.

Wald froze for a moment, then jerked his head up.

"Reacquaint yourself."

Colin smiled and stretched out his hand and said, "My name is Colin Vane, the designer of the photograph. ”
