Zhang Fan and Xiaoying were shocked for a while, and hurriedly covered their ears and shouted: "Wow, what are you doing, old man, your ears are almost deaf........."

At the same time, in the cultivation room, Elder Li and Xiao Fei were closing their eyes and concentrating on protecting Zhang Fan's Dharma, but at this moment, a sonic boom burst from Zhang Fan's body in an instant, and it was directly transmitted into the distance, Li Lao and Xiao Fei were so frightened that they didn't react to this situation that could be said to be without warning, and in the next second, the two reacted at the same time, and directly pounced in front of Zhang Fan, both wanting to forcibly interrupt Zhang Fan's absorption process.

But just when the palms of the two were about to touch Zhang Fan's body, a sudden change occurred, and they saw that the flesh-colored spiritual core that had been stored in the dantian by Zhang Fan emitted a strong pink light at this time, and directly formed an egg-shaped spiritual power barrier around Zhang Fan, which firmly protected Zhang Fan, and the palms of Li Lao and Xiaofei were shocked at the same time as they touched the barrier, and the two of them were directly shocked to the wall of the cultivation room.

Li Lao grew his mouth in horror at this time, and he was able to shake his spiritual power back, indicating that the spiritual strength of this barrier was at the same level as himself, how could this appear on the body of a novice, after all, Li Lao was a master at the level of a spiritual general, and it was naturally much better than Xiao Fei, who fell to the ground panting, and quickly stood up, rushed to Zhang Fan again, and once bombarded the barrier, only to see that the barrier was even more immobile than just now.

Seeing this, Boss Li was shocked and called out to Xiaofei: "Girl, at least this barrier is something I can't break, hurry up and call the commander over, hurry, I'm afraid that Zhang Fan, this kid, won't know what's going on." ”

At this time, the spiritual power barrier didn't know if it was because of the attack by Li Lao, or because of its own reasons, the barrier actually rotated slowly, Xiao Fei saw this, and knew that things were in trouble, whether it was because of the unknown spirit core, it was better to terminate Zhang Fan's current state as soon as possible, so he couldn't take a breath in his breath, and directly broke out of the door to find Jiantian Peak.

When Li Lao and the two were at a loss outside, Zhang Fan here in the water pavilion felt that the sound had stopped, so he slowly let go of his hands, looked at the trembling shadow next to him, and after making sure that it was okay, he looked at the old man suspiciously, only to see the old man at this time, looking at the iron ball on the table with a smile on his face, and nodded and said: "I really don't know whether to say that your kid is lucky or fate, and you will find such a strange treasure in such a barren place." ”

Zhang Fan rubbed his ears, vaguely heard what the old man said about the strange treasure, and asked loudly: "Old man, what are you talking about?!"

"Ouch, be quiet, my old ears are about to be deaf by you. ”

Zhang Fan turned to his ear and clearly heard what the old man said: "Come on, you, if you were deaf, you would have been deaf a long time ago, just now I was really deaf, what are these iron balls." ”

The elder dodged Zhang Fan's loud voice, and waited until Zhang Fan and Xiaoying had slightly recovered their sense of hearing before continuing to explain: "This iron ball is a kind of extraterrestrial meteorite that has been wandering in the universe for hundreds of millions of years, and it is an extremely rare one. ”

Zhang Fan cleared his ears, heard what the old man said about the meteorite outside the sky, and said that it was so precious, he said angrily: "I thought it was something." It turned out to be a few pieces of meteoric iron, and my ears were tired. ”

The old man glanced at Zhang Fan speechlessly, and asked speechlessly, "Do you know this meteorite?"

"No, but it's not just a piece of iron, it's just a different place of origin, I admit, meteorite may contain some rare new elements that I haven't seen before, but to put it bluntly, it's not a piece of scrap iron?"

The old man said speechlessly: "It seems that there are things to popularize for you in the future, do you think this is the stone you usually see?" Let's put it this way, this meteorite is the most central and pure matter of a planet after the death explosion, a region of a few kilometers in size, which has been wandering in the universe for hundreds of millions of years, in the excellent melting pot of space, after countless collisions, countless times of scorching, countless times of cooling, and countless times of squeezing, it will take hundreds of millions of years to form a small piece the size of a baby's fist, what do you say?"

Seeing that Zhang Fan still looked ignorant, he continued to popularize science: "Strictly speaking, this should not be called meteoric iron, but should be Yuan Jin," the old man picked up the iron ball and let the iron ball levitate on the palm of his hand, Zhang Fan saw that the air between the old man's hand and the iron ball was restless, and it felt like the old man was heating the iron ball, "This is a gold knot that contains most of the elements in the universe, you may better understand it by comparison, what is the hardest substance in your cognition?"

Zhang Fan blurted out without thinking: "Of course it's a diamond." ”

"And what if I say that the diamond is a lump of cotton in front of this dollar?"

"This cowhide is a bit too big. Zhang Fan said in disbelief.

Ming Lao had long known that Zhang Fan would say this, so he directly shook his other hand down in the air, and after more than ten seconds, a small reflective pebble appeared in the hole on the ground.

"You, just kidding, this is, diamond!" Zhang Fan couldn't believe it, this old man just thought that I would condense a diamond directly from the earth? If I also have skills, wouldn't I just go back to the earth? Hurriedly took the diamond, looked at it carefully, either with his teeth or with his hands.

The old man said disdainfully: "Don't be so ignorant, okay, your so-called diamond is just a bunch of carbon atoms, and extracting it is not a matter of raising your hand, now you can smash it with an iron ball, and see what the result is?"

Zhang Fan picked up the iron ball and smashed it violently, only to see that the hardest substance in Zhang Fan's cognition bloomed in just one fell swoop under the destruction of the iron ball. Zhang Fan only now understood why the old man was so happy to find these dozen iron balls, Zhang Fan hurriedly stood next to the old man and asked in a low voice: "That, old man, ask you something, is it difficult to learn your skill of condensing diamonds?"

The old man knocked on Zhang Fan's head, and said angrily: "I said you kid, I'm talking about the important thing, you just want your diamond, it's not difficult, as long as you reach a certain stage, you can do it." ”

When Zhang Fan heard this, his eyes suddenly lit up, and he said righteously: "Okay, I, Zhang Fan, will definitely work hard!" Now that Zhang Fan has this goal, he has made a more stable decision to stay in this Taiyin world and "study".

Seeing Zhang Fan's poor ghostly face, the old man covered his eyes speechlessly and said, "Then, then you can come on, but you should solve the matter in front of you first." ”
