After listening to Jiang Xiaotan's words, William was obviously tempted, but he still asked cautiously:

"What challenge?"

"Can you tell me whether you accept it or not? Or do you mean that you don't even have the courage to accept the challenge?"

Being provoked like this, William's blood was immediately aroused: "Who is afraid? I accept the challenge."

A few weeks later, he deeply regretted his decision.

At the same time, he also discovered that there was something in this world that was more tormenting his brain than a hangover.

That's geometry.

The challenge Jiang Xiaotan gave him was to complete the study of nautical geometry and pass the exam within a month.

After they returned to Cypler, they began to prepare for the Cypler Magic Academy, and Jiang Xiaotan's most important subject here was nautical geometry.

Of course, it is also because the magic lecturers from West Francis have not come yet, so we can only offer this class now.

Since the construction of the school building has not yet started, the college has been temporarily placed in Margaret's Crimson Castle. Of course, this is only a temporary measure, and a special school building will definitely be built for the college in the future.

Even if it can't reach the level of Huo Sha Wo Sha, at least it can't make it a Ba Sha Sha Demonic Castle.

The first batch of students were naturally selected from active sailors, and an extra William was added.

Before sending William in, Jiang Xiaotan specifically "encouraged" William and said: "If you fail in the challenge, it means that you are not qualified to conquer the deep sea at all. You will just be an ordinary stormtrooper captain for the rest of your life, and then

In this era when boarding warfare is about to be completely eliminated, let us become the tears of the times."

After receiving such a provocation, William tried his best to let Jiang Xiaotan see the bloody nature of an East Francis man.

However, he soon discovered that there was a reason why his family had not produced a mage for more than ten generations.

He had no idea how to fit numbers into formulas, just as he had never learned how to fit runes into magic spells since he was a child.

After studying for a few days, William collapsed.

He feels that geometry is actually closer to the category of philosophy.

Lovers will betray you, comrades in arms will betray you, but never.

If you don’t know geometry, you just can’t.

For this reason, Daisy Li, who was originally responsible for teaching necromancy, dedicated her time playing chess and entertainment to tutor William.

The reason is simple. As a Francis, Daisy doesn't want William to give people the bad impression that "Francis are all idiots".

But after a few days of counseling, Daisy became a little desperate.

She even went to Jiang Xiaotan to complain:

"Other students can quickly accept the theory that the sum of the interior angles of a triangle is equal to 180 degrees, and can use parallel lines to prove it, but this idiot insists on saying that he has cut three identical triangle handkerchiefs. No matter how he puts them together, it will not work.

It cannot form a perfect straight line, so the sum of the interior angles of the triangle must not be 180 degrees."

"Didn't he ever think that it was because the lines he cut were not straight?"

"That's right! William reminded me of a student I taught in Paris decades ago. I asked the student to try to imagine 'the feelings of the deceased,' but the idiot student killed himself."

"Well, but judging from the results, you, the student, know how the deceased felt, right?"

"In short, I don't care about this idiot! Let him go out and stop saying that he is a Francis!"

Daisy was so angry that she slammed the door and left.

However, since Daisy stopped caring about William, William seemed to have enlightened.

He began to work harder and spent a lot of time studying geometry.

If you don’t understand the principles, just memorize the formulas by rote. If you’re slow at arithmetic, practice more.

This hard work paid off for him.

In the exam a month later, William, who was sallow and skinny from studying all night, scored 59 points.

Jiang Xiaotan read the paper several times, secretly helped him correct an obscure mistake, and then wrote a red 60 with the magic pen that he had finally repaired.

It can be considered that he succeeded in his challenge.

However, Jiang Xiaotan also required that the newly appointed chief mate must continue to study in the academy until he fully masters all knowledge of navigation geometry before he can go to sea.

Anyway, William proved that he has the perseverance and hard work to become a first mate.

It also proves that some people are really not suitable for learning geometry.

After the first phase of training in the academy, the mages from the Mages Council who came to build the Magic Source Tower also arrived in Cypler one after another.

They also brought news from Aichen. Ryder VII had received the first batch of cannons shipped by Cypler. After the old king actually saw the power of the cannons, he was very satisfied with the transaction and even asked the wizard to

They brought extra thank you gifts.

At the same time, the mages also tactfully expressed to Jiang Xiaotan that the old king was "very eager to see the second batch of cannons."

Of course, Jiang Xiaotan must show a positive response to this request from his allies.

Since the test of the rifled cannon went smoothly and a large number of new cannons had been installed, he immediately transported a batch of old cannons that Constantine had replaced and sent them to the ship in front of the mages, and told the mages that this was "

A cannon that was in service just a moment ago”.

This noble character of "weakening" one's own defense power for the sake of allies moved the mages very much.

However, what the mages lamented even more was the speed of construction of the base of the Sepule Demonic Source Tower.

Due to the use of vampire craftsmen, this tower was built at a speed that was incredible to the mages, so much so that when the tower was raised, the mages had not even finished charging the magic source.

Because the mages delayed the construction period, the construction of the Magic Source Tower was delayed to three months. At this time, the foundation of the Matheri Magic Source Tower, which was started at the same time, had just been laid.

By the way, at this time, William's score also improved from 60 points to... 57 points.

Since the basic construction of the Magic Source Tower has been completed, the content of calculating coordinates through the distance measurement of the Magic Source has also been added to the course, which made William's little mind even more troubled.

It seems that he has no hope of catching the first batch of deep-sea adventure fleets.

However, after the construction of the Magic Source Tower was completed, Jiang Xiaotan postponed the progress of the deep-sea exploration for some reason and returned to Constantine.

Because there was news from Duke Maxine of Rotum.

After investigation, Rotum's ranger troops found the remnants of the "Pure Hunter Alliance" that had been operating on the border of Rotum, and discovered the traces of their leader, the former "Silver Hand of God" hunter Spencer.
