The Heavenly Ghost Emperor approached the bronze door, stretched out his palms, and with a loud shout, the two brass doors babbled open, slowly sliding backwards, and a wide passage appeared in front of him.

The Heavenly Ghost Emperor smiled: "The door has been pushed open, and there will be a period later!" "It seems that he feels that he has taken a big advantage, for fear that according to the rules of human beings, he will be eaten by humans again.

After saying that, his body disappeared into the darkness and slipped away.

Lin Yang smiled and shook his head, this Heavenly Ghost Emperor is a cute rectum, just like his eldest apprentice, Yue Laosan.

The gate was pushed open, Lin Yang and Jiang Wan'er continued to move forward, led by Jiang Wan'er, and walked through a few poor roads, and finally stopped in front of a big hole.

Jiang Wan'er said: "This is the end. ”

Lin Yang frowned, "The end? ”

Jiang Wan'er said: "Other roads may lead to the inside, but there are other demons guarding them, and they can't pass, and there is no passage for demons to block the way, and in the end it is here." ”

After a pause, he said, "This is the place where the immortals in the book practice." ”

Lin Yang smiled and said, "It turned out to be him, let's go, go in and have a look." ”

The immortals in the book, the immortals hidden in the book of heaven, read a lot of books during his lifetime, and did not forget to read after his death, he knew everything about astronomy and geography, and he could be called the fairy sword plane.

The two of them walked inside, and the stone room was empty, except for a gray-haired, hobbled old man, dressed in Confucian clothes and standing with a cane.

The old man looked at Lin Yang coldly, then turned to Jiang Wan'er and said, "When I'm reading, I don't like others to disturb me the most, why did you bring someone here?" ”

Jiang Wan'er lowered her head and didn't speak.

"Don't embarrass the little girl!" Lin Yang raised his eyebrows and said, "I'm here to find someone, my daughter-in-law Zhao Ling'er was arrested in the tower and seems to be imprisoned at the bottom. Tired of leading the way? ”

It is said that this lock demon tower is like a labyrinth, and there are many monsters blocking the road. If you want to find Zhao Ling'er, if no one leads the way, you have to work hard with your old nose!

If Jiang Wan'er didn't lead the way, it would be even more difficult for Lin Yang to find the immortals in the book.

The fairy in the book said indifferently: "Why did the old man show you the way?" ”

Lin Yang smiled and said, "That's it." I'll give you a problem, and if you can solve it, I'll leave. If you can't, please lead the way. ”

Excited by Lin Yang's arrogant words, the fairy in the book almost jumped up, his face couldn't help shaking, and said, "What did you say!?" Ha, ha, the old man's life has read all the subsets of scriptures and history. Read the works of the hundred schools of thought, and after death, attach the spirit to the book, and for five hundred years, he has visited countless scriptures in the three worlds of heaven, earth and man. In terms of the depth of knowledge and the breadth of knowledge, even the gods and Buddhas of the heavenly realm may not be comparable to me, and you and other juniors dare to give me questions? Ha, ha. It's ridiculous! ”

Lin Yang said lightly: "If you don't dare, forget it!" ”

The immortal in the book took a deep breath and said, "You test me?" Good. Take the test as you like! If you have a problem, I won't know it, and I'll die in front of you! ”

Lin Yang smiled, stretched out his hand, and pointed at the sword, and slashed to the ground in the air. The sword qi passed, and a string of marks appeared on the ground.

Hao Ran is: 1+1=?

Jiang Wan'er and the immortals in the book looked at each other, not knowing why.

The immortal in the book stared at Lin Yang for a long time, and said angrily: "You and other juniors." Dare to play tricks on the old man, what kind of ghost is this? Is it also a question? ”

Lin Yang smiled and said, "Of course it's a question, can you do it?" If you can't, throw in the towel! ”

In the book, the immortal said angrily: "What kind of title is this? You can explain it to me, if you can solve it, the old man will admit defeat! ”

"That's what you said." Lin Yang smiled, and slashed to the ground again, and the sword qi passed, and characters such as "0,1,2,3,4,5,6,7,8,9" and "+-x÷" appeared on the ground.

Exactly the Arabic numerals as well as the symbols of addition, subtraction, multiplication and division.

The immortal in the book looked at these characters, and then looked at the previous title, vaguely felt that they had some kind of connection, and couldn't guess it, and couldn't help asking, "What is this?" ”

"It's one, two, three, four...... It's addition, subtraction, multiplication, division......"

Lin Yang explained Arabic numerals, as well as the application of addition, subtraction, multiplication and division, such as the ninety-nine multiplication table, which primary school students will have, to the scholars one by one.

The more the immortals in the book listened, the more excited they became, and finally, looking at Lin Yang, they shouted excitedly, "Listening to your words, I suddenly opened my mouth and saw a new realm!" See a new realm again! ”

As he spoke, the Shushu Immortal bowed to Lin Yang and said, "The student has seen the teacher. ”

There is no end to learning, and those who reach it are the first.

Elementary school students will have a question, impressed by an immortal in the book who knows everything about astronomy and geography.

"That's it!" Lin Yang waved his hand, secretly amused, and said, "Can you lead the way now?" ”

"Students don't dare!" In the book, Xian Liandao didn't dare and asked, "The teacher is looking for someone?" Well, Wan'er has always taken this path, and it ends at my end...... If the teacher has come in all the way and hasn't seen your friend, then she may really be imprisoned at the bottom, the way to the bottom, not this one. ”

Lin Yang said: "Which road leads to the bottom?" Stop the ink, let's go! ”

The fairy in the book nodded honestly, and sighed again: "It's no problem for me to lead the way, but it's just ...... Alas, I have never been very fond of walking that road, because on the way I will meet some abominable demons, stupid and stupid, all of them are the shame of demons. Since the teacher has a life, the student has to lead the way! ”

Lin Yang said helplessly: "Hurry up and lead the way!" ”

"Students obey!"

The immortal in the book nodded, led the way in front, and met some demons on the way, and saw that the immortals in the book retreated, which shows that the mana of the immortal in the book is also extremely high.

The lock demon tower has always been the weak and the strong, you eat me, I eat you, the immortals in the book can survive so far, the demons avoid, showing good strength.

In the end, after sending away a contemplative ghost in the lock demon tower, the group of three came to the demon pool.

In the book, the fairy said while walking: "This tower is built with diamond white jade, and the inside and outside of the tower are full of forbidden spells of high monks and mages, so you can only enter, not out."

And even at the bottom, eleven giant swords were lined up in formation, sealing the earth's qi.

In order to prevent us from destroying the formation, the tower builder filled the place where the giant sword stood with demonic water, forming a demonic pool.

If a demon gets a drop of demon water, he will have to turn off half of his body, not to mention the whole person diving, so as long as we don't use the brains of the sword array, the water in the demon pool will not threaten us. ”

The more the group walked, the more open and cheerful the road became, and at the end of this place was a huge hall of tall and wide, with a flat ground and a bright pool of clear water in the center, like a huge and incomparably luxurious water mirror.

There are many majestic pillars standing in the giant pool, and the reflection is in pairs, which increases the momentum.

Among the beautifully carved stone pillars, on the sword pillar in the center, Zhao Ling'er was locked with a gold chain! (To be continued......)
