In the book, it is said that the sea of knowledge is the most vulnerable place for all cultivators, and if they can attack the sea of knowledge, it is basically equivalent to being invincible. However, it is a pity that the book does not say how to launch the Zhihai attack.

It seems that this book is useless, I thought. However, the method of entering the fifth layer is much simpler, it is written on the stone wall that as long as the strength reaches the standard, and the method of testing the strength only needs to use your own vitality to light the glass lamp in the middle of the pavilion.

It seemed that there was nothing I needed on the fourth floor, so I walked into the library and began to pour my vitality into the glass lamp.

Not to mention that this lamp is by no means an ordinary product, my own vitality is extremely powerful, and the amount of vitality is even wider than that of the Liangyi realm, and it took me forty percent of my vitality glass lamp to shine slightly.

However, having a bright light also means that success is close at hand, and finally when I poured more than ninety percent of my vitality, the glass lamp illuminates the entire library.

At this time, I was not in a hurry to enter the fifth layer, and decided to recover my vitality on the fourth layer first.

At this time, a scene appeared in the library, Mo Xiao and Mengdie had already entered the third layer, and at this time, Wang Lung was missing by his side, presumably he should have entered the second layer, and he had already left the library when the time came.

I passed the second floor very quickly, and it took me ten days to be mainly on the third floor, and I don't know how long the two of them will be trapped on the third floor, but to my surprise, Mo Xiao entered the library two times before, but he was stuck on the first floor, and he didn't even enter the second floor, and this time I don't know what happened, and if someone accompanied him, the progress was much faster.

I don't know how long it took for two more portals to appear around me, and Mo Xiao and Mengdie walked in.

"You haven't made it past the fourth floor, we thought you'd already be on the sixth or seventh floor," said Mershaw.

"Well, I'm afraid you're stuck in the fourth layer, why don't you just learn something here and leave one last chance, and at least reach the Liangyi Realm and then break through the fifth layer," I opened my eyes and said.

"Ahh

"You can try it, the condition for passing through the fifth floor is to pour your own vitality into the glass lamp in the middle of the library to make it illuminate the entire library. My true strength is no less than that of the Liangyi Realm, or even higher, but it took me more than ninety percent of my vitality to light this lamp, so I regained my strength here. With that, I pointed to the glass lamp.

"Is it so difficult?" Mo Xiao didn't believe it, and walked over and began to pour vitality into the glass lamp. After a while, his face turned pale and stopped.

"I'll go, sure enough, it's the same as Jiang Ye said, Mengdie seems that the two of us are going to stop here this time. Mo Xiao sighed.

"It doesn't matter, we still have a few months to practice, and the Xuanmen resources are so sufficient, we will definitely be able to reach the Liangyi Realm. "Mengdie doesn't care too much about that.

"I calculated, one day in the outside world is equivalent to twelve days in the library pavilion, you still have ten days to go, try to learn as much as possible in these ten days, the last chance to save it and wait for enough strength to come back" I stood up and said again, "Now that my strength has recovered, I'll go up to the fifth floor first"

"Haha, I really envy you," Mo Xiao smiled.

"Don't be envious, you'll come up too," I replied.

"Well, Brother Jiang is back and will teach us more experience, remember," Mengdie said mischievously.

"Well, how could I forget you, hahaha" I turned and jumped into the portal.

Entering the fifth floor, a little boy looked at me with a smile on his face.

"Are you a book spirit?" Seeing that this little boy was dressed like a little girl on the second floor, I couldn't help but think that he was a book spirit.

"Well, have you seen my sister?" the little boy laughed. This little boy has a good personality, unlike the little girl, who has an arrogant temperament.

"Haha, your sister is an interesting child," I laughed.

"She, don't worry about being young, if there's anything wrong with my son, I'll apologize for my sister. The little boy bowed.

In an instant I reached the little boy and stopped him from bowing to me.

"No, your sister's personality is lively and cute, I like it very much," I said, and my impression of the little boy was much better.

"And what are the conditions for accessing the sixth layer this time?" I added.

"I only need to test a few questions from Childe, and if you answer correctly, you can enter the sixth layer, and of course Childe can also stay on the fifth floor to study," the little boy said respectfully.

"Ahh

"Childe just listen," the little boy laughed.

"The first question, people who cultivate immortals pay attention to the avenue, the avenue is righteousness, the avenue is ruthless, and the righteousness destroys relatives. On the way to cultivating immortals, those who cultivate immortals must follow the Great Dao, which is the rule that the world's Xuan Xiu must abide by, if there is a time when the son must face the choice of the avenue and affection, how will the son choose" The little boy looked at me politely and waited for my answer.

I was silent and frowned, "I will abide by the laws of the Great Dao, but if I want to give up my dearest and loved ones to abide by the Great Dao, I don't think I can do it." What I've experienced since I was born has never been fair, and my life may not be understood by others. ”

"Does the boy mean to give up the avenue for affection?" said the little boy.

"The Great Dao is ruthless, if you can't protect your loved ones on the way to cultivating immortals, then what kind of Great Dao can you cultivate, I believe that people are not ruthless animals, and besides, you will also care about your sister, right?" I said again.

"Well, Childe's words are refreshing to me," the little boy laughed.

"The second question, what is the purpose of Childe's cultivation, or why does Childe cultivate?"

"I'm not trying to be strong, I'm just being forced. Everything I was born with was unfair, because of fate, my grandfather died tragically, my lover died young, and the people around me who were related to me were in dire straits. If I'm not strong, how can I protect them? Why do you cultivate the Tao just to protect the people around you? I said calmly.

"Question 3, what if one day Childe stands at the top of the world?" the little boy asked again.

"Standing at the top, I have never thought about this, and I have never known what it will be like for me to stand at the top, but at least I know that the cultivator can only last long if he maintains his original intention, no matter what position I stand in the future, I believe that my original intention will not change. If one day I do evil, it will not be an exaggeration for everyone in the world to eliminate me," I said.

"Okay, Childe is the second person I have ever seen with such an upright temperament, you can enter the sixth layer. The little boy said.
