Xu Bing originally had a lot of pressure on the old man, but at this moment, he quickly rushed to Fancheng after the old man left. But not long after leaving, the old man's voice came from behind him again.

"Little doll, wait for my old man".

Xu Bing stopped and looked back, only to see the old man's body walking in the air, originally dozens of zhang away from him, but at this moment, he came to him in an instant.

Xu Bing bowed to the old man very respectfully, "Senior, I don't know what to tell the younger generation to stop."

The old man looked at Xu Bing, and a slightly kind smile appeared on his face. He beckoned to Xu Bing and said, "You come here, come here."

Xu Bing didn't know what the other party was looking for him, but he didn't ask any more, but came to the old man's side and waited for the other party to speak.

When the old man saw Xu Bing coming, he stretched out his right hand into the placket of his chest and groped for a while, which looked very similar to Shen Cong who touched the ingots on his chest during the battle with Xu Bing before. However, Xu Bing didn't say anything, just waited quietly.

The old man fumbled for a while, stopped the movement of his hand, smiled very satisfied, "Found it", and then took out his right hand.

In the old man's right hand, there was a milky white ball at this moment. The ball was smooth, bigger than the old man's palm, Xu Bing's face suddenly had an incredible look, and he didn't know how such a big ball was put in the placket of the old man's chest.

The old man took out the ball, stretched it out and put it in front of Xu Bing, and then said, "Little doll, put your palm on it, and then concentrate all your energy to observe this ball."

Xu Bing didn't know the old man's intentions, but he did so, spread out his right hand, placed it on top of the ball, and stared at the ball with his eyes to see if there would be any changes.

After five breaths, a faint white halo suddenly appeared on the ball, and this light ball was restrained, without the slightest trace of emission. Seeing this, Xu Bing suddenly understood that what the old man was holding in his hand was actually a pre-spirit stone.

The pre-spirit stone he had seen before when he was testing the disciples of the Cloud Holy Sect was about a zhang high, and it was columnar, and although the surface was smooth but not flat. Just now when he saw the old man take out the ball, he just felt that the material of the ball looked very familiar, but he didn't think about it, but now when he saw the pale white halo, he realized that what the old man was holding was a pre-spirit stone that had shrunk many times. And the pale white light cluster presented in the sphere was the too rare Lei Linggen that Song Chen's senior uncle had said before.

However, the old man didn't know what Xu Bing thought in his heart, he looked at the light cluster in the ball, frowned, and whispered to himself, "No, could it be that my old man guessed wrong." Also, this hidden spirit root is so rare, how can it be so easily touched by me."

Although he said this, the old man did not have the slightest intention of giving up. He observed again for a moment, and then said to Xu Bing, "Little doll, come on, take a drop of your blood and drop it on this ball, don't be afraid of pain, don't be afraid of pain." After the old man finished speaking, he looked at Xu Bing expectantly.

When Xu Bing heard this, he also knew that this old man did not have any ill will towards him, and it was even possible that he had found something useful for cultivation in himself, so he did not hesitate any longer, took out the dagger, and swiped it lightly on his fingertips, and the blood suddenly flowed out of the wound and landed on the ball below.

The old man suddenly retracted his expression at this moment, quieted down, stared at the ball in front of him, and even held his breath.

One breath, two breaths......

Until the five breaths had passed, the ball had not changed at all, and the old man's brows furrowed again, and even his mouth pursed, so that he looked like an angry child.

But just as he was about to take the ball back and leave, the originally dim light in the ball became a little brighter than before.

This sudden change immediately attracted the eyes of both of them. I saw that the originally faint pale white light cluster had become much brighter than before, and even larger than before, but the light cluster was still only restrained, without the slightest hint of being released.

Time passed breathlessly, and in the old man's observation, the light cluster in the sphere did not continue to grow, but inside the light cluster, there was another light cluster that was smaller than the other but completely different.

It was a pale yellow light cluster, which was a circle less than this white light cluster, and when he saw this, the old man suddenly became happy. As if he didn't know how to express the joy in his heart, he raised his hand and patted Xu Bing's shoulder, and said three times in a row, and then continued to observe the ball.

Another five breaths of time passed, and this time not only the old man, but even Xu Bing saw that inside the pale yellow light cluster, another light red light appeared.

This was not the end, almost at the same time, inside the pale red light, another pale blue halo appeared. At this time, the old man was stunned, as if he had seen something extremely incredible, but his eyes were still staring at the ball, as if waiting for the next change.

However, the old man's wait this time did not change in exchange for any changes, and there were still only four colors of light in the ball. Those light clusters are smaller than ever, wrapped layer by layer, all of them are brilliant and restrained, and it is difficult to find them even if you don't look closely.

After another five breaths, the old man was sure that there would be no more changes, so he let out a long breath, "Oh my mother! I'm scared to death my old man, this will have one more color, and I guess the old man will be excited to return to the West." The old man smoothed his chest as he spoke, as if he was really afraid that he would die if he couldn't get up in one breath.

"Heavenly Spiritual Root, Heavenly Spiritual Root, Heavenly Spiritual Root, Heavenly Spiritual Hidden Spiritual Root, What kind of shit luck did my old man take, and he was able to find such a young man."

As the old man was talking, he suddenly turned his head to look at Xu Bing, and said with a solemn face, "Little doll, oh no, little brother, do you want to practice? Do you want to become an immortal? Do you want to have the ability to move mountains and reclaim the sea? You give the old man and me an apprentice, and the old man will teach you well, and you will definitely be more powerful than my old man in the future." The old man shook Xu Bing's shoulder as he spoke, as if he was afraid that the other party would not agree to him.

Xu Bing was a little confused by the situation in front of him, and he didn't know what to say for a while. After all, in the previous test of the Cloud Saint Sect, the result he got was that his spiritual root was weak and he couldn't cultivate. But looking at this old man's appearance now, it seems that he can practice, and his qualifications will definitely not be low.

The old man didn't know what Xu Bing was thinking, but when he saw that he didn't speak, he hurriedly spoke again, "Oh, little brother, little brother, don't stop talking." No, no, big brother, I'm your little brother, tell me quickly, do you want to practice? I will be your teacher, I will teach you to practice, and in the future I will be your master, and you will be my eldest brother."

The old man said with a smug look, as if he was very satisfied with his words.

But these words fell on Xu Bing's ears, but they made him even more surprised, but he didn't dare to offend the old man in front of him, so he said, "What do seniors mean that they can also practice with the qualifications of younger generations"?

"Oh, what seniors and juniors, my eldest brother, of course you can practice, if you can't practice a spiritual root like yours, then there are still a few people in this world who can practice."

"But seniors, the immortals of the Cloud Saint Sect came to Fancheng to recruit disciples before, and the juniors also participated in the test, but the result was that the juniors had weak spiritual roots and could not practice, and the seniors said at this moment that the juniors' qualifications could be cultivated, why is this?"

"Oh, you said Yun Shengzong, the one who came to Fancheng to accept apprentices this year is the little doll surnamed Liu, he is so cultivated, how can he see so many mysteries. I can tell you, this spiritual root of yours is very special, and ordinary people really can't see it. But...... Hehe, old man, I have a special method, so I can discover your special spiritual root."

"How about it, do you want to know what is special about your spiritual root? If you want to know, you can worship me as a teacher, and then I will tell you."

After this short contact, Xu Bing already knew that this old man's personality was a little strange, but at least he also saw the scene of the ball, and there was no need to lie to this old man if he wanted to come. After thinking for a while, he finally made up his mind and said to the old man, "What the seniors say, the younger generations believe, since the seniors are willing to accept the younger generations as apprentices, it is also the creation of the younger generations, and the younger generations are certainly willing."

When the old man heard this, he immediately laughed a few times, and shouted in his mouth, "Old man, I also have an apprentice who can handle it, haha......" After speaking, he looked at Xu Bing again, and said again, "Good apprentice, come and apprentice, I will teach you skills after worshipping." After speaking, he looked at Xu Bing with a very expectant look.
