Depending on the situation, the changes that happened to Ye Shisan's body came from this sword.

This strange sheathed long sword completely attracted Zhang Yuan's attention. So the next moment, Zhang Yuan took the black long sword on the ground into his hand.

Holding the hilt of the sword, Zhang Yuan closed his eyes and sensed, and his huge spiritual power swept through, and he didn't find anything special.

Next, Zhang Yuan used the true qi in his body and slowly injected it into the sword.

True Qi probed into the sword body, and immediately reacted, wisps of black light bloomed on the scabbard, swimming, and crawled towards Zhang Yuan's hand, looking extremely spiritual.

Seeing this, Zhang Yuan did not stop it, but instead increased the output of true qi, and tried frantically on the verge of death.

Of course, Zhang Yuan has a system in his mind to guard, not afraid of any spiritual attacks, and he is wearing purple gold heavenly wings on his body, and he has the hegemonic body skill in his body, which can be immune to all controls. It seems to be an act of death, but it is actually a stable horse.

However, others didn't see it that way, and around them, everyone in the Tiger Roaring Martial Arts Hall was nervous, watching Zhang Yuan's action of holding the sword, and his footsteps moved back vigorously.

In the field, the black light on the black long sword skyrocketed, and a faint sword intent appeared between heaven and earth, and in an instant, the spiritual domain emanated by Zhang Yuan was torn apart by an extremely sharp aura, and the black mang flashed, and this wisp of sword intent directly entered Zhang Yuan's eyebrows.

"Ding, the virus intrusion is found, the automatic defense system is activated, and the intrusion virus has been wiped out. ”

"Ding, the source of this virus has been detected, do you trace the source and erase the source of this virus?"

Hearing the system prompt in his mind, Zhang Yuan smiled indifferently and replied in his heart, "No!"

Opening his eyes, Zhang Yuan swept the long sword in his hand for the first time, and found that it had regained its calmness, coldness, and no previous spirituality.

"Brother Zhang Yuan...... You...... Are you alright?"

At this time, Ye Thirteen's voice came.

"It's okay!" Zhang Yuan raised his head, and what caught his eyes was Ye Shisan's little face as pale as snow, "Brother Ye, what happened just now?

Ye Shisan shook his head, glanced at the black long sword held by Zhang Yuan in his hand, his eyes were complicated, and he said, "I'm fine, it's just that the consumption was a little big before." ”

Hearing this, Zhang Yuan nodded, his eyes turned from Ye Shisan's body to the long sword in his hand, and his left hand lightly supported the sword body, looking at the lines on it, he always felt familiar.

"Huh, this isn't ......."

Zhang Yuan exclaimed in surprise and almost jumped up.

As soon as the thought moved, a large number of obscure characters were found from the depths of his memory.

These characters were forcibly poured into his mind by the Purgatory Demon Venerable not long ago.

Looking at the lines on the sword again, Zhang Yuan found the corresponding part in these characters in the depths of his memory.

If the lines on the sword body are spread out and connected, they can form a coherent line of characters. These characters have their meanings in Zhang Yuan's memory, and after translation, they are four words Blood Sea Purgatory.

The Blood Sea Purgatory is the first realm of the Dao-level exercise "Purgatory Demon Sutra", and it is also the most basic layer.

"This sword must be related to the Purgatory Demon Sutra, maybe it is used together?"

There are so many thoughts in my mind that I simply don't think about it anymore. Zhang Yuan withdrew his mind from his mind, tightened the long sword in his hand, raised his head again, and looked at Ye Shisan.

Seeing Zhang Yuan looking over, Ye Shisan took a deep breath and said first, "Brother Zhang, there is a reluctant request below, it is related to my future martial arts, please be sure to agree!"

Brother Ye said. Zhang Yuan said immediately.

Ye Shisan looked at the long sword in Zhang Yuan's hand, sighed slightly, and said, "I want you to help me keep this sword, and then return this sword to me when I have cultivated to the realm of a grandmaster." ”

"Huh?" Zhang Yuan raised his eyebrows and looked at Ye Shisan with some confusion, "Why is this?"

"Hahaha!" Lin Wuhu's laughter came at this moment.

Seeing that everyone's eyes were looking at him, Lin Wuhu put away his smile and said with a serious face, "Zhang Shaoxia, you don't know anything." When the thirteenth little brother Ye broke through the Demon King Altar before, he actually comprehended the sword intent! This is the sword intent! How many people who practice martial arts dream!"

"It's a pity...... Little Brother Ye Thirteen's sword intent was comprehended too early, if he entered the innate realm, he could directly use the sword intent to break through all the way, and improve his cultivation to the realm of a martial arts grandmaster without any side effects!"

"Alas, it's a pity that the thirteenth little brother Ye is only a cultivator of the acquired realm, and he can't withstand the power of the sword intent at all, and he is devoured by it, and he directly loses his mind. ”

Speaking of this, Lin Wuhu paused, glanced at the black long sword that Zhang Yuan held in his hand, and continued, "Brother Ye Thirteen's body can't withstand the power of the sword intent, so this sword intent is inhabited in this sword. ”

"Since the Thirteenth Little Brother Ye has already comprehended the sword intent, his martial arts path is naturally smooth before the Grandmaster. However, if you don't reach the Grandmaster for a day, you can't come into contact with this sword intent, otherwise you will inevitably be attacked again, and you will lose your mind at least and lose your cultivation at worst. ”

"Now it seems that it is a good choice for Zhang Shaoxia to keep this sword for the time being, hello, hello, hello, everyone!hahaha!"

After listening to Lin Wuhu's words, Zhang Yuan groaned slightly, nodded slightly, and said, "Okay, I will keep this sword first, if you break through to the grandmaster, just come to me and get it back." ”

"Hmm!" Ye 13 clasped his fist at Zhang Yuan and said, "Thank you, Brother Zhang!"

"By the way, Brother Zhang, will you continue to stay in this city for the next period of time?" Ye 13 asked.

Hearing this, Zhang Yuan shook his head and said, "I have stepped into the rivers and lakes, and the road ahead is to fight the sword world, slay demons and eliminate demons! ”

As soon as these words fell, Ye Shisan's eyes lit up, and he said to Zhang Yuan, "Even if it is the world of swords, why not join me?" When I came out of the clan, I brought a detailed map of the entire northern region, and several of my teachers have drawn a detailed road map for me. ”

After speaking, Ye 13 reached into his arms and felt out a thick pile of paper.

"Space equipment?"

Seeing Ye Shisan take out the item from his arms again, Zhang Yuan finally confirmed one thing. Ye Shisan is really from a big family, and he has a lot of money, and he even has space equipment.

I just don't know if there are a lot of gold coins on him......

After a few turns of thought, Zhang Yuan finally put his eyes on the map in front of him.

In front of him, Ye Shisan's hands unfolded a map, which was about this nameless city. In the lower right corner of this map, there is a small mark on the nameless deserted city, the formation pattern is incomplete, there is no ability to defend against foreign enemies, and there are no innate warriors in the city.

The map in Ye Shisan's hand continued to unfold, and the next one was a place three hundred miles south of the Nameless City, which seemed to be a steep mountain range, and the lower right corner was also marked with the Black Wind Mountain, hiding the Black Wind Old Demon who had once run rampant, and because he was cursed that his cultivation had fallen below the grandmaster, he lived in seclusion here with the wealth accumulated in half his life.

"Stop, stop!" Seeing this, Zhang Yuan's eyes couldn't move, "Living here in seclusion with the wealth accumulated in half a lifetime?"

"It's done!" Zhang Yuan clapped his hands, put his arm on Ye Shisan's shoulder, and said, "Brother Ye, it's decided, let's fight the sword rivers and lakes together, and kill the demons!"
