"Here it is, are you sure? This looks like a very ordinary grass shed? How can there be a grass shed here?" Zheng Xuanyi stood in front of a dilapidated grass shed, and asked a little disbelief, this is not to blame him, this is obviously a forest, there will be a grass shed here, even if you are lucky and not discovered, you can wash it down with a little bit of cruel weather, not to mention that there are small animals in the forest, and even spirit beasts.

"Yes, this is it, I left some of my belongings here at the time, and today is a bargain for you kid. The old man shook his head and smiled: "Let's go, let's go down." ”

"Go down?" Zheng Xuanyi just wanted to ask how to go down, but suddenly felt that the soles of his feet were empty, and his body sank, "Ah......hhh

"Hey, what kind of place is this?" Zheng Xuanyi stood up with his dizzy head, and behind him, the old man's voice came out, "Little guy, why don't you hurry up and get the light out, do you want to go on like this?" old man, I don't care, but you ......"

Zheng Xuanyi left without finishing his words, the flames were beating in his palm, shining on the road in front of him, Zheng Xuanyi said in front: "Senior, hurry up, how are you going to go next?"

The old man only realized at this time that Zheng Xuanyi was actually so far away from him, and immediately shouted: "Can you kid listen to the old man and finish my words." ”

"Yes, yes, but can you hurry up, I'll listen to your nagging later, let's end the matter here quickly, and I'll go back to class." Zheng Xuanyi nodded and said, the pace under his feet did not stop.

Although the old man was very unhappy, he still floated and followed.

"Boy, you have to be careful about the next road. The old man reminded.

Zheng Xuanyi didn't answer, looking at the flat road in front of him, he also knew that there must be something strange about it, so he made a brief observation, and said very seriously: "Well, you say, what's the problem here." ”

The old man was instantly defeated, and said irritably: "Ahhh......h I'm going crazy, why do you have to study for so long since you don't know anything, do you know how shameful it is to waste time, and aren't you yourself saying that you don't have enough time, and you even waste time, thinking back then, old man, I ......"

This time, the old man was very cautious to see if Zheng Xuanyi had listened carefully, and sure enough, Zheng Xuanyi was in front of the wall on the side, looking at something thoughtfully, and suddenly pressed his finger on it, and then there was a sound, on the side, a secret passage appeared, Zheng Xuanyi looked at the old man, and asked, "This is a safe passage, right?"

The old man was stunned and said, "How did you find it?"

"Isn't it written here? Zheng Xuanyi pointed to the side of the place where he pressed just now, and a few words were written on it, "The safe passage is here."

The old man was petrified instantly, and he only then remembered that this was the passage he had set up for himself at that time, and he was afraid that he would forget, so he specially wrote a text on the side, but now...... Forehead. The old man looked at Zheng Xuanyi and found that Zheng Xuanyi was looking at him with a contemptuous gaze, as if asking, "Aren't you very shrewd?

"Ahem......" The old man coughed to hide his embarrassment, and hurriedly said: "Didn't you kid say that you were in a hurry? ”

Zheng Xuanyi withdrew his gaze from him and walked into the passage, followed by the old man. It took them a long passage to reach their destination.

"Is this it?" Zheng Xuanyi asked, looking around.

"Yes, this is where the old man rests. The old man's tone was very sad.

Zheng Xuanyi heard it, and hurriedly said: "Senior, you ......" However, Zheng Xuanyi found that he couldn't comfort him at all, so he chose to be silent.

"Heh, the old man is just touching the scene, don't take it to heart. The old man wiped away the tears that could not be seen, and suddenly said: "Go ahead, the thing on the far left is what I said can help you, just pick it up and refine it, but you have to be careful, refining this thing will not be simple." ”

"yes, I see. Zheng Xuanyi nodded, and slowly walked to the place where the old man said, the first skeleton he saw was a skeleton with some shabby clothes on it, this corpse should be the old man, Zheng Xuanyi endured the smell and bowed to it, the old man's soul body nodded with relief when he saw Zheng Xuanyi's respectful appearance in the back, with a smile on his face, and muttered: "It seems that I didn't look at the wrong person, old man......"

Zheng Xuanyi gradually approached the skeleton and found a sign next to it, which read "Lin Xian's Tomb", Zheng Xuanyi turned around and asked, "Senior, your original name is Lin Xian." ”

"Yes, it's just that I don't know how many people in the world still remember the old man's name, hehe......" Lin Xian's soul laughed self-deprecatingly: "Why are you still stunned, don't you go quickly." ”

"Yes. Zheng Xuanyi said respectfully.

Zheng Xuanyi came to the item that Lin Xian said, it was a spar, after so much time, there was still a faint light on it, as soon as Zheng Xuanyi approached it, the light on its body became even more dazzling, Zheng Xuanyi looked at it and said, "This is the auxiliary core?"

The auxiliary core is the container that carries the formation diagram, and the material used to make it is the ordinary spiritual core, which is carved on the spiritual core with the help of soul power, and the content of the carving is the array diagram, which is one of the items most needed by all Yuan Spiritual monks.

And the person who carves the auxiliary core must also be a Yuan Spiritual Cultivator, and they have another name, called Spirit Carver, and the financial and human resources they have are absolutely beyond your imagination, so it's better not to provoke them at will.

The auxiliary core in front of Zheng Xuanyi looks like a disc from the top, and looks like a deformed spinning top from the front, but the so-called people can't look good, and of course this auxiliary core is the same. Zheng Xuanyi had seen the auxiliary core at that time, but all the auxiliary cores he had seen before did not feel stronger than the one in front of him, and the fire element that appeared on it was like a spring, and the ordinary auxiliary core could not be compared with it at all, so how powerful was the array engraved here.

Zheng Xuanyi solemnly held it in his hand, sat cross-legged on the spot, and entered the state of cultivation. Zheng Xuanyi's side gathered a lot of fire elements at once, and they were all frantically pouring into that auxiliary core, and at the same time, Zheng Xuanyi's soul power was pouring in. This is a necessary stage in the process of refining the auxiliary core, you need to use your own soul power to feel the array engraved in the auxiliary core, and then guide that array into the spirit core in your body, and then let the array blend with the spirit core in your body, so that the refining can be considered successful.

However, there is a little bit of risk when refining auxiliary cores, that is, the array inscribed in the auxiliary core may exceed the upper limit of the refiner's tolerance, which will lead to the refiner's life danger, so generally the refining auxiliary core will start with the lowest auxiliary core, and then slowly refine the higher auxiliary core, that is, the stronger formation diagram.

The auxiliary core will be shattered after the transfer of the array inside, and it will no longer have any effect, which means that the auxiliary core is a consumable, which is one of the reasons why it is so precious.

Lin Xian looked at Zheng Xuanyi nervously from behind, and muttered: "Stinky boy, you must hold on, this auxiliary core has not reacted since I got it, and you reacted immediately as soon as you touched it today, which means that you must be its destined person, so you must come on." ”

......

In Ling Tian Academy, Bing Yiru was the first to wake up. The ice blue light spread out like a disturbed lake, and Bing Yiru's beautiful figure appeared in front of the people around her, Bing Yiru smiled faintly, "It seems that the harvest is good." ”

Bing Yiru just wanted to leave, but was suddenly pulled by a person, and she didn't react for a while, only to find that the person who was holding her was Yun Jing, Yun Jing's face was flushed, obviously after a strenuous exercise, "Xiao Yi, something happened, Xuan Yi, Xuan Yi He is gone." ”

"What does it mean to be gone?" Bing Yiru was first stunned by what Yun Jing said, and disappeared?In the academy?Impossible, right?Bing Yiru asked, "He's such a big person, are you still afraid that something will happen to him?"

"No, it's not, it's that Xuan Yi's mood is not very good, which is why I'm so worried about him. Yun Jing shook his head and said.

Bing Yiru immediately thought of the Demon Dragonborn, and said, "You say slowly, don't worry, tell me what's wrong first?"

"Hmm. Yun Jing nodded, and briefly told Bing Yiru what had happened before.

Bing Yiru pondered for a while, and said to Yun Jing: "Let's go and ask Dean Xuan first, we should be able to find out if he is in the academy, if he is fine, if he is not, then ...... A little troublesome?" Bing Yiru always felt that something was wrong, she didn't believe that Zheng Xuanyi was a self-defeating person, as could be seen from the fact that he once challenged Xing Xiaohao.
