Three months later, in the very center of Shizhu Island, the capital of the Tuhao Empire, the colorful chameleon rock square, the flags were displayed, and the crowds were crowded.

A rare scene in a century is being played out here.

The people were clamoring and the vendors were numerous.

The masters of the rivers and lakes are out of the nest, lurking in the dark, stirring up the storm.

The wealthy families sent their generals to seize the advantageous terrain.

The central court selected the elite of the imperial forest and guarded the surrounding areas of the square.

They gathered here for one thing: the Abacus Tower, which had been open for three months, would be automatically closed in three days. And none of the twenty-four students who entered the Star One Academy have not yet come out.

If the time limit expires, they will remain trapped in the Tower until twenty years later, when it is reopened.

Twenty years in the outside world is equal to two hundred years in the Star Calculation Tower, and even if they are not dead at that time, I am afraid that they will all be separated from the Dragon Bell and will die soon.

This is a great matter, and the royal families of all countries have urgently sent envoys to inquire about the exact news.

He Qianliu, the emperor of the Tuhao Empire, felt a little anxious.

In the past few days, he has not known how many groups of people he has received, and he has said all the good things and worn out his mouth. Although he is a master in the world, he cannot stand the whole continent from coming to crusade against him! In order to show his sincerity, he personally set up a platform camp in the Colorful Chameleon Rock Square, staring at the star calculation tower on the Colorful Chameleon Rock every day, and even the slightest change will affect his heart.

At this moment, what are you doing?

The Tuhao Empire is known as the center of the Qinglong Continent, and Shizhu Island is the center of the Tuhao Empire, and the colorful chameleon Square is the center of Shizhu Island.

Colorful Rock Square is one of the largest squares in the world, and there is no one.

In the middle of the colorful rock square, there stands a huge rock with a width of about 600 meters, a length of more than 900 meters, and an average height of 12 meters. This rock will change with the change of weather and rain, and it will show seven colors of red, orange, yellow, green, cyan, blue and purple, which are unpredictable and magical.

The Star Calculation Tower stands on this colorful rock.

Shi I Dao is taking dozens of tutors from the First Star Academy to sit in a circle around the Star Calculation Tower.

They had already prepared to join forces to destroy the Star Calculation Tower in case no one came out when the time came.

However, the Star Calculation Tower is the inheritance of the Crescent Moon Empire's national treasure, and of course the people will not agree to destroy it like this, so the envoy groups of various countries are urgently negotiating with the Crescent Moon Empire Envoy Group, after all, the third princess of the Crescent Moon Empire, Moon Bai, is also in the Star Calculation Tower.

Moreover, no one is sure that after destroying the Star Calculation Tower, they will be able to rescue the people inside the Star Calculation Tower, which is just one more option.

The star abacus tower is divided into five floors, three floors and below, and people outside can see the dynamics inside, just like looking at the fish inside through a crystal fish tank, but the people inside look much smaller than the fish, probably the size of the smallest red ant.

However, this is only the effect of direct gaze.

Ordinary people simply don't have the opportunity to get close and look straight ahead.

Of course, you don't need to look at it directly.

After the Star Calculation Tower is opened, it will automatically project twenty-four giant phantom light curtains in the air, clearly showing the whereabouts of the twenty-four members inside as they are, until they enter the fourth layer of the Star Calculation Tower.

This is the legendary Star Tower Phantom.

Everyone can learn about the situation inside the Star Calculation Tower from the Star Tower Phantom.

However, the Star Tower Phantom also leaves a certain amount of privacy for all members. The members inside only need to cast the stealth secret method provided by the Star Calculation Tower to temporarily cut off the projection of the light curtain.

Now, the phantom of the Star Tower shows that there are four people on the first floor of the Star Calculation Tower, nine people on the second floor, and eight people on the third floor, these eight people are He Xiaoduo, Long Yuandong, Dugu Wenjiao, Shui Xue, Gong Luoluo, Long Xinnan, Mu Buqi, Wu Zuwei, above the fourth floor, there are only three people, these three people, one is Yun Tianjia, one is the crescent moon, and the other is Shi Zhengyang.

The fourth and fifth layers are invisible, and everyone has no way of knowing what is going on in Yun Tianjia, Shi Zhengyang, and Crescent Moon.

The five floors of the Star Calculation Tower represent the five realms of Star Calculation.

From low to high, it is divided into instrumental arithmetic, arithmetic, adjustment arithmetic, mental arithmetic, and Taoist arithmetic.

Those who enter the Star Calculation Tower can only go up to the higher level only if they pass all the assessments of the lower level.

What is instrumental calculation?

To learn from things, to take what can be used, is to calculate for the instrument.

There are agriculture, medicine, soldiers, arrays, rituals, households, criminals, workers, officials, dozens of positive calculations, music, chess, calligraphy, painting, embroidery, divination, physiognomy, business, magic, acting ten pairs of calculations, animal taming, refining medicine, refining tools three constant learning, a total of 23 learning, anyone who can be familiar with any two of them, can get a one-star inheritance, is an instrument arithmetic.

After becoming an instrument arithmetic, you can enter the second floor of the Star Calculation Tower.

In other words, the four people who are still on the first floor of the Star Calculation Tower are not even instrumental calculators.

What is arithmetic?

Touching the analogy bypass, drawing inferences from one another, is for arithmetic.

As the old saying goes: A gentleman is not a weapon.

Youyun: The gentleman hides his weapon in his body and moves when the time comes.

After a person becomes an instrumental arithmetic, he just allows himself to have basic skills, which is equivalent to carrying some kind of tool with him. But the use of tools also requires skill, when to use them, when not to use them, if they are used, to what extent, and what impact they may have.

If you can open your eyes, adapt to complex environments, and know how to advance and retreat, you can obtain a two-star inheritance and become an arithmetician.

He Xiaoduo's assistant teacher, Wen Yanxin, is a two-star arithmetic. But his star arithmetic level is assessed by the Ministry of Rites, and he has never entered the star arithmetic tower.

What is Adjusting?

Familiar and flowing, peeking at its true mystery, is for calculation.

As the saying goes: "The sky does not say anything but moves at all times, and the earth does not say anything but all things are born." ”

There is a certain law in everything, and people only need to "do what they want and do it naturally." "In the depths of the twenty-three disciplines of instrumental arithmetic, you will often find that there are many things in common. If you have mastered several or even more than a dozen disciplines of knowledge into a furnace, you will find the universal laws in it, the falling leaves know the autumn, the leopard is seen, the outline is given and the eyes are open, and the solution of a volume is clear, which is for the calculation.

The adjuster has a three-star heritage.

What is mental arithmetic?

One yin and one yang, moving appropriately is for mental arithmetic.

The interpreter has a cloud: "Ten thousand laws start from the heart, and the heart gives birth to ten thousand laws." The soldier also said: "Fighting after battle, the art of war is constant, the use is wonderful, and there is one heart." ”

Mental arithmetic masters peek through yin and yang, understand creation, are familiar with the disadvantages of the six desires and seven emotions, master the changes of good and evil in yin and yang, and are subtle.

Mental arithmetic is a four-star inheritance, and in the whole world, there are only a few star arithmetic masters who have reached the realm of mental arithmetic, which is even more scarce than the tenth-order Contra Douluo.

The final reckoning is also known as divine reckoning. No one knows how God interprets and evaluates it. For thousands of years, I have never heard of anyone actually entering the realm of divine calculation.

Just when the teacher and the teachers were worried, and He Qianliu and the envoys from various countries were thinking hard about countermeasures, the people in the square were already talking enthusiastically and spitting.
