Those who can use the heaven and earth bag are powerful warriors, and there will be more treasures in it. The golden light will play out, and the mouth of the heaven and earth bag will open. After all, the master is dead, and even if there is a martial idea on it, it can be easily erased.

"There are so many black dragon arrows in the universe!"

Sun Yi's eyes lit up. The universe bag counted the black dragon arrows in detail. He was overjoyed that there were 14 black dragon arrows. He also saw the power of the black dragon arrows. The frontal battle may not be very powerful, but it's better to use it for sneak attack.

One arrow can determine the life and death of heaven and earth. If each black dragon arrow is used well, it can kill half the king.

Sun Yi secretly liked to put the black dragon arrow into his heaven and earth bag, and then cleaned up the other treasures in it.

There are some heaven level magic tools, as well as many yuan stones and pills, but Sun Yi doesn't care much about it. With the improvement of his realm, many heaven level magic tools can't enter his eyes. What he pursues now is a powerful immortal level magic tool.

Sure enough, when Sun Yi was exploring the heaven and earth bag, he found a brocade box made of precious sapphire in the corner. It was about three feet long. There was a black dragon carved on it, and the dragon head roared and circled in it.

"This is...!" Sun Yi's eyes stared at the boss, opened the brocade box, and a black roar of the Dragon roared towards him. The golden Wutai town suppressed the roar and looked at it with five arrows.

The arrow is black, not very smooth, with some potholes, but this does not hinder its horror. It is like a real black dragon inside, and the arrow seems to fly out.

"This is the arrow made of the bones of the black dragon. The bow and the arrow are the real matching, very strong." Jin Shu was always paying attention to the outside world at the moment. With his insight, he recognized the origin of the arrow at a glance and reminded him.

"Immortal arrow." Sun Yi touched his hand on the arrow of the black dragon. A strong evil spirit and unwilling to rush into the sea made Sun Yi tremble in his heart. The black dragon didn't know how many years he had died and still kept that unwilling.

"What a powerful arrow. How powerful should fairy level arrow be with fairy level bow." Sun Yi secretly praised. I'm afraid that those who are not strong enough will be destroyed by this unwilling anger with this black dragon arrow.

"Quickly put away the arrow and go to get the prison killing door." Jin Shu hurriedly said, making Sun Yi look cold. The prison killing gate is the son of 36 heavenly magic weapons, and he has seen his power.

Sun Yi looked at the whole battlefield. The prison killing door was lying quietly on a flat ground at the moment. The two doors up to two meters were closed now, and the surging murderous spirit disappeared.

Sun Yi stepped forward quickly, looked at the prison killing door, touched his nose and found that he couldn't put it into the heaven and earth bag. He couldn't help asking, "what should I do?"

"Dripping blood to recognize the Lord, this is the child door of the magic instrument of heaven. I will help you suppress it." The Golden Book said solemnly.

"Well, I believe you."

Sun Yi nodded solemnly. The golden blood essence dripped and integrated into the prison killing door. After the prison killing door integrated into the blood essence, it moved in Sun Yi's eyes, turned into a small door of the thumb door at a speed visible to the naked eye, and slowly printed Sun Yi's head.

"Don't panic."

Jin Shu reminded Sun Yi that he completely let go of his mind and let the prison gate enter his sea of knowledge.

Now Sun Yi knows the sea.

The door of killing life seemed to be spiritual. It flew towards Sun Yi's fifth martial platform and stood directly on it. The two closed doors immediately opened and a sense of killing solidified into black gushed out.

"This killing intention!"

Sun Yi's martial spirit is like being in Jiuyou hell. The golden martial spirit seems to be getting dark and cold. He wants to transform his martial spirit into a killing machine that doesn't know his thoughts. Even with Sun Yi's firm martial heart, he can't resist it.

The black tide surged one after another. Sun Yi clenched her teeth, and the Wu soul sent out golden light to resist the pervasive black light.

"A small sub gate also dares to be presumptuous in front of me. Your main gate still has that qualification here."

A roar of thunder like that from the nine days exploded in Sun Yi's sea of knowledge. The soul of the martial arts trembled. The Golden Book immediately emitted dazzling light like the sun. The golden light was shining everywhere, sacred and fierce, as if it was the enemy of the prison gate, and the light of the way from the nine days away.

The two forces fought in Sun Yi's sea of knowledge. The golden light of the Golden Book became more and more prosperous, and the prison gate trembled more and more, as if unwilling to be suppressed by the Golden Book.

"Give it to me honestly for my use!" There was another sound of loud drinking. In the Golden Book, there seemed to be a great figure in the golden light. It was real and empty. There was a force that seemed to surpass the law, which blew on the killing door and directly closed the two doors.

The black killing power also disappeared immediately. The martial spirits were all loose and sat at the gate of the prison.

"The strength is too weak. It takes so much effort to deal with a small gate. Boy, look for some souls to make up for me in the future."

After all this, Jin Shu gasped for breath and said with self mockery.

"Is that all right?"

With a puff, Sun Yi's body sat on the ground and his whole body was sweating. Without the hand of the Golden Book, his soul would be gone. This door was not easily touched by him.

"OK, just don't use more power than your strength when you use the killing door in the future, otherwise I will consume my power to help you suppress. My old bone has consumed all the power absorbed these days."

Jinshu joked that after such a long time together, he found that he had some feelings for the boy, tenacity and great perseverance.

"That's good."

Sun Yi tried to use the prison killing door, and the virtual shadow of the door appeared behind him. The prison killing door spewed out a killing intention, which seemed to form the power of a field, the power of killing everywhere in the field, but this killing intention had no impact on him. This may be the repression mentioned in the Golden Book.

"Feel this power. If you are strong, this Taoist gate can form a real killing field. Powerful killing villains can appear in the field to kill for you, but the strength of killing prison villains is determined by your will and soul."

Jin Shu talked with great assurance and asked Sun Yi to nod his head and say, "yes, it's a good baby. The people in the holy palace gave me such a good thing."

"Not only that, the prison killing gate can sharpen your martial soul and make your martial heart stronger. The prison killing power has both advantages and disadvantages. The strong can be used for themselves, and the weak will only be assimilated by him."

Jin Shu continued to introduce that when he was in Jiutian mainland, his master was also shenhuangjing. He got a sub gate and honed himself with the help of the sub gate, so that he could really use all the strength of the prison killing gate. This boy was lucky and had him to help him hold down the town.

"Thank you this time."

Sun Yi sincerely thanked him. Without the Golden Book, he would never grow to such a point. This thanks came from the bottom of his heart.
