The next morning, President Grantis's office on the third floor of the Inspectorate.

"Elder," Donner spread out the paper in front of Grantis, drawing the seven bridges, "I was to the southern suburbs of the Holy City once during my vacation. ”

"I know ...... this place," Glentis wondered, looking at the manuscript paper, "when did you build these bridges?"

"My lord, I drew these bridges, and they don't ...... in reality," Donner explained, scratching his head.

"What are you painting these bridges for? is it the same question as Vincent's question, to find the shortest path?" Grantis shook his head slowly, looking a little dissatisfied.

"My lord, I originally had the same idea as Venerable Vincent," Donner laughed, "but after drawing the seven bridges, I found something interesting. ”

"Oh, tell me?" Grantis stared at the map on the paper, wondering what interesting thing Donner would say.

"My lord, you can try to see if you can complete these seven bridges in one go without repeating or missing them......

"Neither repeat nor omit?" Grantis looked at Donner thoughtfully, "If you say that, you must have tried, right?"

"Yes, my lord," Donner replied with a serious expression, "I've been trying for a long time......"

"No?" asked Grantis.

"No, I can't. Donner frowned and shook his head.

"Really?" Grantis seemed unconvinced, and traced his finger on the paper, "I'll try ......"

"Shall I go down first, then?" asked Donner.

Grundeon let out an "um", his eyes still resting on the paper.

......

On the second floor of the Superintendent's Society, Donner's own room.

On the spread out animal skin, he was drawing another first-level fire magic array: the Flame Ball.

Prior to this, Donner had already tried, taking the magic array drawn by others, it was useless for the brain to accumulate data, for this, he didn't know the reason for the time being, and could only guess that the brain probably needed to sense and record the magic fluctuations in the process of drawing the circle.

In order to help Zhi Brain accumulate data, he had the intention to draw all the known first-level magic arrays, but in this way, it would be impossible to improve as before.

In about an hour, he finished the magic array and began to draw the next one.

The first-level fire magic array, according to the slight difference in effect, is divided into a total of nineteen kinds, this is still a fire magic array with fewer types, if it is replaced by wind and wood, this number is much larger.

He had calculated that there were as many as one hundred and forty-two first-level magic arrays in the five series, and if one was drawn every hour, even if he didn't sleep, it would take six days to draw them all.

In fact, the time he spent now on drawing the magic array every day would not exceed nine hours, that is, one hundred and forty-two pieces, and it would take at least half a month.

Moreover, in order not to affect the reputation of the work, he will not print his name on these magic arrays, in this case, more than a hundred magic arrays are worth dozens of blue crystals, and there is no point in even selling them.

But in order to achieve the purpose of analyzing the magic array, he could only insist.

......

When President Grantis knocked on the door, Donner hurriedly gathered the clutter and papers on the table in front of him, covering the paintbrush, magic gold, and half-drawn circle.

As if he had calculated the time, Donner had just finished all this when Grantis shook his head and pushed the door in: "John, I can't try it either......"

"Your Excellency, do you think there is no way to do this?" asked Donner, feigning doubt.

"I don't know......" Grantis frowned, "I think it's an interesting question, though." ”

"Well, my lord, I have a way to give it a try...... Donner whispered for help, "Can we just build these seven bridges...... Then set up a bonus, and if someone tries successfully, ...... it."

Before Donner finished speaking, President Grantis was already shaking his head desperately: "No, no, absolutely not......"

Sure enough, as Nancy said, anything related to money is not negotiable with President Grantis.

"Your Excellency, listen to me," Donner said with a smile, "You see, during this time, the Inspectorate has accumulated a lot of problems, and none of them have been solved......"

Elder Grantis's face was a little embarrassed, indeed, from the Fermat conjecture, the four-color conjecture, to the Seven Bridges problem, plus a few cartography problems found by the other vice presidents, the Inspectorate had accumulated a bunch of questions, all of which were unresolved.

"Your Excellency...... Since we have limited manpower, it is impossible to find a suitable person willing to join the Inspectorate in a short period of time......" Donner shook his head in frustration, and then continued: "Can you get the Chigashan to pay for the establishment of a bonus, but anyone who can solve any problem, whether it is the Inspectorate or not, can get this bonus......"

"This ......" heard that it was to ask the Chiga Mountain to pay for it, and President Grantis was no longer as resistant as he had just been.

"My lord," Donner continued, "With these rewards, don't talk about others, even within the Superintendent's Society, everyone will be much more motivated to do things......"

"You can try......" Grantis finally nodded, he knew what Donner meant, except for the president himself, everyone in the Overseer Society probably spends a lot of time elsewhere.

"If the Chigayama are willing to pay, I think this problem of the Seven Bridges can be used as an opportunity," Downer suggested, "You see, the problems we have encountered before will take a little time to describe them clearly. But this seven bridges are different, as long as the bridge is built, and a sign is erected next to it, everyone can understand it...... Maybe someone will make a special trip to visit for the prize money or just curiosity. ”

"That makes sense," Grantis said, "When the time comes, we can publicize other issues and prize money there, and I'm not afraid that no one cares......"

"That's a good idea," Donald nodded, "Or will you be thoughtful...... you will grow?"

Grantis smiled and glanced at Donald: "Don't be slippery, I know you thought of this a long time ago......"

Donner smiled embarrassedly, and then said seriously: "My lord, I think that if the bonus is set too low, I am afraid it will not have any effect. ”

"No," Grantis said with a wicked smile as he pointed at Donner, "John, do you already have an answer?"

Donner's expression became more serious: "My lord, I swear, if I am the first to think of how to cross these seven bridges, I will donate the prize money to the Superintendent's Society." ”

Grantis smiled and waved his hand, "John, are you serious...... Haha......"

Donner laughed along, but for a completely different reason.

Of course, Donner couldn't find a way to complete the Seven Bridges without repeating or omitting them, but he knew it couldn't be done, and now with the help of his brain, it shouldn't be difficult for him to prove it.

However, it doesn't matter if the Seven Bridges issue is proved or not.

As long as Chigashan agreed to set up various bonuses, Donner was sure to ask questions himself, and then find someone to answer on his behalf, covering all the bonuses.

Moreover, he was convinced that the Chigayama's attempt to seek the gods of light and the mysteries of magic through the Governor's Society was doomed to be in vain.
