Is this the spiritual eye that opens the pineal gland of the brain?

Yan Liqiang, who opened his eyes, looked at the space that became normal again in his eyes, and his heart was filled with shock.

The 108 alien beast core crystals were still placed on the table, and they all looked the same from the outside, but at this time, Yan Liqiang was no longer confused. He stared at the alien beast core crystal that looked completely unique just now, and then walked up and held the alien beast core crystal in his hand.

Close your eyes again and spread your spiritual eyes. The strange beast core crystal in your hand turned into a blue light, and the strange rune appeared and disappeared in the light.

Open your eyes...

The alien beast core crystal is still the alien beast core crystal.

"It turns out that the Death Gate of the Crystal Tower of the Sword Cave is really the Sword God Sect who is selecting disciples who can inherit the inheritance of the formation talisman master!" Yan Liqiang murmured to himself. At this time, if he still doesn't understand what the sixth level is testing, then he would be a little stupid.

He had almost never touched the talisman master's profession. The only thing he had ever contacted with the formation talisman master before was the spiritual aura talisman protected by the Shatu priest. When he first saw the energy shield that could not even be shot in the Shatu priest, Yan Liqiang was so surprised that his chin was about to fall off. He had never thought that in this world, besides martial arts, there was such an incredible secret technique.

Things in the world are unpredictable. In the blink of an eye, he may become a formation talisman master in this realm of Heavenly Dao.

After standing there for a while, after turning all kinds of thoughts in his mind, Yan Liqiang took the alien beast core crystal in his hand and came to the iron table in the middle of the house. Without hesitation, he put the alien beast core crystal in his hand into the groove in the iron table.

It was magical. While the strange beast core crystal was put in, the strange beast core crystal that had just emitted a strange red light instantly flourished, and Yan Liqiang, who was standing in front of the iron table, shone blue all over. Then the iron table sank to the ground silently. On one wall of the room, a crystal door slid silently, revealing the passage to the seventh floor.

Yan Liqiang took a deep breath and walked towards the passage.

At the entrance of the channel, there is still a line of words.

——The spiritual eyes are natural, and the talent is superb, so you can go up to the seventh floor.

What kind of test does the seventh floor of the crystal tower have? With such a question in mind, Yan Liqiang took a deep breath and walked up to the seventh floor. In less than half a minute, Yan Liqiang arrived at the hall on the seventh floor.

Unlike the sixth floor, the entire seventh floor hall was very spacious. In the whole hall, there was only an iron table that was larger than all the iron tables downstairs. On the ground next to the iron table, there were a bunch of square bricks. Yan Liqiang walked closer and saw that the things placed on the ground next to the iron table were not bricks, but square metal blocks. There were numbers carved on the metal blocks. There were exactly 81 metal blocks, and the numbers on the squares also ranged from 1 to 81.

"What are you going to do?" Looking at the things on the ground, Yan Liqiang grabbed his head. Seeing that there was a piece of paper on the iron table next to him, Yan Liqiang picked up the piece of paper.

——Congratulations, there are no disciples who can come here. You have used your strength, luck, and super talent to prove your qualifications to get here. Even if you cannot pass the next level, you will also receive a reward to enter this level. This reward is "Swordsmanship" one of the four great skills of the Swordsmanship. "Swordsmanship" is an innate secret technique and can directly point to the path of heaven and man, which is definitely not comparable to ordinary martial arts secrets. In addition, you can also obtain the right to use the Canglong Cave in Dijian Valley for seven years. All of this is well deserved.

——The test on the seventh floor is the last level in the Death Gate. For many people, this level is also the most difficult level. After passing this level, there will be no further test. You will go straight to the ninth floor. If you can pass this level on the seventh floor, then you will have more rewards. Not only will you get all the rewards on the seventh floor, but you will also have greater gains on the ninth floor. That harvest is the strongest inheritance of the Sword God Sect. It will allow you to embark on a more glorious path. This path will surely make you famous all over the world and stand at the peak of humanity in the entire Silver Continent in the future. At the same time, it will also allow you to have an incomparable position in the Sword God Sect.

——The previous levels, some test your character, some test your strength and luck, some test your courage, some test your talent, and some test your talent. What this level will test will be another kind of talent and talent.

——There are eighty-one grids on the iron table in front of you, and there are eighty-one numbers on the ground next to you. If you put the numbers into the iron grid, as long as the horizontal line, vertical line, and two diagonal lines are added to the sum equal to 369, then the last door will be opened for you.

——The way of heaven means that all things are in form and their spirit is number!

Yan Liqiang looked at it twice, and couldn't help but open his mouth. He never expected that the final test of the seventh level was his mathematical ability. The eighty-one grids in front of him, the eighty-one metal characters on the ground, and the requirements on the paper were clearly required to complete a ninth-level fantasy square within a limited time.

The rewards on the seventh level are not related to the formation talisman master, but the levels on the seventh level are closely related to mathematics. This makes Yan Liqiang have an idea in his mind. Do you need to have good mathematical abilities to become a formation talisman master? The formation character of the formation talisman master seems to have some slight relationship with mathematics...

The last sentence on the paper - the way of heaven is the form of everything, and the spirit is the number! Yan Liqiang read it carefully twice and found that this sentence has a profound meaning. This sentence may be a bit difficult for people in this world, but for people like Yan Liqiang, his understanding of this sentence must be more profound, because all the sciences he saw and understood in his previous life were based on mathematical research. To a certain extent, this was also touching the "Tao"...

In the Silver Continent, when it comes to the Nine Palaces, many people can say that the Nine Palaces are two or four as shoulders, six or eight as feet, three on the left and seven on the right, nine on the right, and five on the center. The Nine Palaces is the simplest third-level fantasy square, the Nine Palaces Wind Shadow Step that Yan Liqiang practiced before, which is a martial art evolved from the Nine Palaces.

There may be someone above the third-level illusion square, and Yan Liqiang has never heard of anyone who can study this. Even a master like Zhang Yourong, who has stopped studying this path before the sixth level. For many martial arts practitioners, it is like asking them to complete a sixth level illusion square. It is like taking their lives. Giving them ten years may not be able to study it. It is better to let them fight on the life and death stage.

If someone else comes, even the elders of the Sword God Sect or the masters of the mechanism like Zhang Yourong may be crazy when facing this level, but for Yan Liqiang, looking at the level in front of him, he felt that this was simply a benefit for him.

"Does the person who set this level know that he had a nickname called the little prince of mathematics in his previous life?" Yan Liqiang murmured to himself. There are actually many solutions to such odd magic squares, such as Robert's method, Bashe method, Triangle cutting and repair method, which can easily get the final answer. There are definitely more than one correct answer for the ninth-level magic square. In the blink of an eye, at least two correct answers appeared in his head.

There was an answer in his head, and Yan Liqiang was not idle in his hands. He bent down and picked up the metal square carved with the word "一" from the ground and inserted it into a grid on the iron table in front of him.

It took less than two minutes before the last number on the ground was inserted into the last grid on the iron table, and the iron table sank silently into the ground. The crystal door of the last level finally appeared in front of Yan Liqiang.

——For those who correspond to the Tao, please go to the highest level of the Death Sect!

There was still a sentence hanging at the entrance of the crystal door. Yan Liqiang took a look and walked up directly.

The journey of going up this time was particularly long. Because there was no eighth floor, Yan Liqiang went directly to the highest ninth floor.

The space on the ninth floor of the highest level of the Crystal Tower is smaller than the spaces below. Just in the middle of the nine-story space, there is an ordinary wooden table. There is a futon on the ground next to the wooden table, and two boxes made of pure gold are placed on the wooden table. Yan Liqiang walked to the wooden table, sat cross-legged on the futon, and opened the first golden box on the left. In the gold box, there was a secret book of strange texture. The materials of the secret book were a bit like the half golden bell cover obtained by Yan Liqiang. There were three words flashing light on the secret book - "Swordsmanship".

Yan Liqiang took a deep breath and suppressed his inner excitement. Then, he opened the golden box on his right hand. There was only a strange piece of crystal in the golden box, with a few words on it - "Taiyi Shifu Jing".

Now that he posted, Yan Liqiang swallowed...
Chapter completed!
