"Well, Zhou Lei, you first go to the Library Pavilion to exchange for the exercises of the Mortal Bone Realm. As for spirit beasts, I suggest that you don't sign a contract at the Tiger Nine City Turtle Academy for the time being. ”

"Most of the spirit beasts assigned by the Tiger Nine City Xuangui Academy are not qualified. Signing these spirit beasts will not do you any good. Elder Ningjiu said.

"If you enter the Xuan Tortoise Sword Sect, it would be most appropriate to choose a spirit beast."

"Of course, Zhou Lei, you have a good chance of entering the Xuangui Sword Sect."

"Thank you Elder Ningjiu for the reminder." Zhou Lei saluted and said.

"Go ahead, there are less than two years to go, and I will be able to cultivate. In the Xuan Turtle Sword Sect, it is even more cruel than the Xuan Turtle Academy. Elder Ningjiu patted Zhou Lei on the shoulder and left the class.

Outside the classroom, Kang Tian was bored looking at the beautiful scenery around him. Seeing Zhou Lei walking out, he hurriedly took a few steps forward and asked, "Zhou Lei, what did Elder Ningjiu say?" ”

"Elder Ningjiu, let me go to the Library Pavilion to select the exercises of the Mortal Bone Realm. And let me not choose the spirit beast too early, and it is not too late to choose the spirit beast when I get to the Xuan Turtle Sword Sect. Zhou Lei replied without concealment.

"Elder Ningjiu is right, whether it is an exercise or a spirit animal, you must be cautious." Kang Tian nodded, and finally made his own judgment.

"Let's go, let's go to the library." Kang Tian pulled Zhou Lei out of the classroom.

Inside the library cabinet, the first floor, is still overcrowded. Zhou Lei entered the second floor of the library under the eyes of Kang Tian.

All the exercises of the Bone Realm are on the second floor of the Library Pavilion. Moreover, only the cultivation of the mortal bone realm can step into the second floor of the library pavilion.

The number of people on the second floor is relatively small, and Zhou Lei chose his own exercises.

Covering the Sky and Angry Waves (Mortal Bones)

Good and evil have a picture of retribution (mortal bones)

Inner Self-Viewing Heaven Array (Mortal Bones)

After Zhou Lei selected three exercises, he looked at them carefully.

All exercises in the Bone Realm can only be watched in the Library Pavilion, and cannot be taken out of the Library Pavilion. Zhou Lei could only look at it here, and the first thing Zhou Lei looked at was the Inner Self-Viewing Sky Array.

Because of the Inner Self-Viewing Heaven Array (Forging Bones), Zhou Lei has not yet practiced.

If you want to practice into a formation, it is simply impossible in the Bone Forging Realm. Only by entering the mortal bone realm is it possible.

To cultivate the formation diagram, you need some precious heavenly and earthly treasures. And the Xuangui Academy only provided it once, and it was also a student who broke through to the mortal bone realm to have this opportunity.

If you fail, you can only prepare your own treasures. And the price of heaven and earth treasure is extremely terrifying.

Although Zhou Lei doesn't know the specific price, it is impossible without thousands of spars.

After reading the exercises, Zhou Lei left the second floor of the library pavilion.

On the first floor of the library pavilion, they found Kang Tian, and the two left the library pavilion.

"Zhou Lei, is the exercise of the Mortal Bone Realm powerful?" Kang Tian was on the way, and asked with some curiosity.

"The exercises of the Bone Realm are powerful, and they are really different from the exercises of the Forging Bone Realm." Zhou Lei replied seriously.

"Where do we go next?" Kang Tian asked.

"Go get something." Zhou Lei said with a smile.

"What a thing?" Kang Tian asked with some curiosity.

"The heavenly and earthly treasure of the cultivation array." Zhou Lei said excitedly.

"Well, if you break through to the mortal bone realm, you can cultivate the formation diagram." Kang Tian said enviously.

"Kang Tian, should I wait for you. When you break through to the mortal bone realm, let's go together. Zhou Lei looked at Kang Tian and said.

"No need." Kang Tian said with some hesitation.

"It's not bad for a few days." Zhou Lei said with a smile.

"Okay then." Kang Tian finally nodded and said.
