"You don't have to serve or anything, just learn from me"

Hearing the word service, Zhang Yuwei's head "boomed", what he couldn't stand the most was this, but in the universe, such things are still extremely common, most of the Taoist couples were masters and apprentices at the beginning, but Zhang Yuwei really couldn't accept this so-called custom.

Since he has accepted a disciple, he must not treat her badly, this is not Zhang Yuwei's style of acting, therefore, Zhang Yuwei began to look for a technique in his soul sea that is not only suitable for the cultivation of the power system of the yin element, but also can cooperate with the refining of the Ghost Heavenly Sword, although Zhang Yuwei has stored countless exercises in the soul sea, but to find such a book, it is still a little difficult, mainly because the grade of the Ghost Heavenly Sword is too low, the ground level of the high-level divine soldier, such a level, to be honest, in the hands of the strong, it is better to burn the fire stick, and therefore, Among the many exercises, there are very few exercises that cooperate with the earth-level divine soldiers.

"I'm afraid I'm wrong, if the exercises can be combined with the cultivation of artifacts and holy weapons, the earth-level divine soldiers will naturally be no longer a problem."

Zhang Yuwei suddenly had a flash of inspiration, he remembered a book suitable for the Yin Element Power System of people to practice the strongest exercises - "Styx Heart Sutra", in the previous life, the Ancestor of the Underworld with a "Styx Heart Sutra", the power of the heavens and all worlds, the limelight was immeasurable, but in the end it was defeated in the hands of Zhang Yuwei, because the Ancestor was too brutal, arrogant and extravagant, making the people miserable, as the Holy Ancestor Zhang Yuwei finally chose to kill the Ancestor alive with his fist, together with his ancestor, Dao Ji was crushed, after killing the Ancestor, Zhang Yuwei obtained this book Heart of the Styx.

The special thing about the "Styx Heart Sutra" is that in addition to improving one's own strength in cultivation, it will also improve the grade of the natal treasure by the way, the Hades ancestor raised his Hades seal to the level of the ancestral weapon, and defeated several ancestral realm powerhouses, compared with the Ghost Sky Sword and the Hades seal, it is not even a scrap, and more importantly, the "Styx Heart Sutra" is extremely suitable for people in the Yin Element Power System, in the previous life, the Sword Immortal Feiyue, a Jindan Realm monk, can teach Qin Yijue to finally reach the Yuan Infant Realm, It is enough to see the strength of Qin Yijue's talent, and with this talent and the Heart Sutra of the Styx, Qin Yijue's future future is immeasurable.

"Qin Xiyan, I will only accept you as an outer disciple, if you can build a foundation within two months, I will officially accept you as my second disciple."

Zhang Yuwei's requirements are not high, with exercises of the level of "Styx Heart Sutra", and a master like him, it is already a long time to build a foundation in two months, if he can't build a foundation within two months, Qin Xiyan will not be able to compete with the Holy Son and Holy Daughter in the great world of the universe, and become a real powerhouse.

He is very confident that he can teach Qin Yijue well, after all, in the previous life, the Sword Immortal Feiyue could make Qin Yijue a success, you know, Zhang Yu was the ancestral realm in the previous life, and the Jindan realm was not even an ant in front of the ancestral realm, after all, the demon god killer ants in the endless sand city had the god realm at the least.

"Sure enough, calling Qin Yijue always feels hairy, let's call her Qin Xiyan."

Zhang Yuwei used the Holy Spirit Eye to confirm Qin Xiyan's realm again, the second layer of the Qi training period, he signaled Qin Xiyan to step back, and he pointed a Holy Dao Killing Tianyan on the tip of his right finger, Zhang Yuwei shot fiercely, and the tip of his right finger pointed at Qin Xiyan's eyebrows, and the Holy Dao Killing Tianyan directly entered Qin Xiyan's eyebrows, and suddenly, the skin of Qin Xiyan's whole body began to turn black, and a trace of black gas came out of her body, unlike magic energy, this black qi was very afraid of the Holy Dao Killing Tianyan, and I couldn't wait to get out of Qin Xiyan's body quickly.

"Is it turbidity?"

Looking at this cheap black gas, Zhang Yuwei frowned, he now understood why he couldn't see the traces of the chess troops, because the chess troops did not use magic energy at all, but used turbidity, but the turbidity was too weak, so that Zhang Yuwei also ignored it.

Qin Xiyan's expression was very painful, she felt as if there were countless small insects crawling in her body, this was the process of the Holy Dao Killing Tianyan forcibly removing the turbidity in her body, Zhang Yuwei knew that for a girl with a low realm, it would be extremely uncomfortable, but if she couldn't bear this pain, it meant that she was just an ordinary person, so Zhang Yuwei did not help Qin Xiyan relieve the pain, but looked at her silently.

Qin Xiyan saw that Zhang Yuwei didn't speak, she wanted to ask Zhang Yuwei for help, but she knew that this would disappoint the master, in the end, Qin Xiyan still chose to forcibly endure the pain, the Holy Dao Killing Tianyan to get rid of the turbidity was not as irritable as burning out the demonic energy, but boiling the frog in warm water was sometimes more painful, Qin Xiyan squatted down, she covered her chest, wanted to scream, but couldn't open her mouth.

"The river of thousands of miles, the confluence of water in the depression, the darkness of ten thousand pours, the accumulation of mountains, the way of the underworld, the ...... of thousands of miles"

Zhang Yuwei saw that Qin Xiyan was too painful, and he still couldn't bear it, he began to recite the beginning of the "Styx Heart Sutra" silently, Qin Xiyan heard Zhang Yuwei's words, and knew that this was the master who was nodding herself, she endured the pain, sat cross-legged on the ground, sank down, and listened to Zhang Yuwei's recitation of the Heart Sutra.

"Styx Heart Sutra" made Qin Xiyan feel an unprecedented power, she felt as if she was in a pure black world, this world made her forget everything, even forget the pain, Qin Xiyan wandered in the pure black world, suddenly, a blue light in front of her attracted her, she stepped forward quickly, and found that it was a sword with a whole body blue.

"A sword?"

In the dark, there seemed to be a great force pushing Qin Xiyan to pick up the blue sword, as soon as Qin Xiyan's hand held the hilt of the sword, the entire pure black world was sucked into the blue sword, in the blink of an eye, Qin Xiyan found herself back to reality, a group of children around looked at her in surprise, she turned around and found that Zhang Yuwei was smiling at her.

"Is it still painful?"

Zhang Yuwei raised his right hand slightly, and withdrew the Holy Dao Killing Tianyan in Qin Xiyan's body, the turbidity had been removed, and there was no need for the Holy Dao Killing Tianyan to be placed in Qin Xiyan's body all the time.

"It doesn't hurt anymore, Master"

Qin Xiyan just wanted to salute, but suddenly found that she was holding a blue sword in her right hand, and there was a circle of air flow wrapped around the sword like a crack in time and space, she looked at Zhang Yuwei in surprise, not knowing what was going on.

"This is your weapon, the Ghost Heavenly Sword, the Heart Sutra of the Styx draws it out of your body, and therefore, this is your natal divine weapon."

"My, Natal Divine Soldier?"

Qin Xiyan looked at the Ghost Heaven Sword in her hand incredulously, she felt that everything in front of her was not real.

"You deserve it"

Zhang Yuwei put his hand on Qin Xiyan's head, his long black hair, not taken care of properly, looked a little messy, he touched Qin Xiyan's head, and smiled with satisfaction, he really didn't see the wrong person, in just a few hours, Qin Xiyan had reached the realm of the fifth layer of the Qi training period.
