Li Chengfeng thought about a way out. He has always been a person who does not believe in evil, so he doesn't believe that he will be trapped here and cannot get out.

Li Chengfeng came to the blocked stone cave passage. He tried to mobilize the immortal power in his body, feeling the power of flowers and plants and trees that could be mobilized nearby.

But within this range, Li Chengfeng could not detect any trace of spiritual power of plants and trees, which made him unable to borrow even if he wanted to borrow it.

This is also the biggest disadvantage of Li Chengfeng's set of exercises at present: he is too dependent on the surrounding environment!

After Li Chengfeng tried to search again, he found nothing and looked at Su Yuehan with a little dejected look. He asked tentatively: "Do you have any solutions?"

Su Yuehan shook her head bitterly.

Li Chengfeng asked without digging his heart, and he said, "Then, now I can find a spiritual crystal to embed it into the Potian Sword. Can the Potian Sword restore its magic power?"

Su Yuehan thought for a while and said, "I don't know, I haven't tried it."

Li Chengfeng immediately dug a piece of spiritual crystal and put the spiritual crystal into the groove of the Potian Sword. However, this piece of spiritual crystal is only the size of a human thumb, but the groove is the size of a pea egg. When the spirit crystal is put in, the sword will fall as soon as it is raised. How can it be embedded?

Li Chengfeng threw the spirit crystal out of a long distance with anger. Then he began to look for larger spirit crystals everywhere, but after Li Chengfeng looked around, the largest of these spirit crystals was a little larger than his thumb, which was completely inconsistent with the spirit crystals needed by the Potian Sword.

Su Yuehan smiled bitterly and said, "This pebbled egg-sized spirit crystal is worth as valuable as a high-level magic weapon. All the top magic weapons in the world are of this size. If it is so easy to find, then the top magic weapon will not be valuable."

Li Chengfeng quickly understood that for a top magic weapon, the most valuable thing is actually three parts, the first: the craftsmanship of the creator.

This craft does not refer to the blacksmith's work, but to the patterned magic array engraved on the magic weapon.

This ultra-small magic array is extremely complex and sophisticated. The drawer must be a person who is very proficient in magic array research and has a very high level of magic power cultivation.

When drawing a magic circle, it is like a person manipulating a huge force and then engraving it bit by bit in a place. The larger the place, the less difficult it is to draw, because the gap between the pattern is also greater.

If this place is smaller, the less difficult it will be to draw, because the gap between the pattern is smaller. Once drawn, the two patterns touch each other, and the magic circle will immediately collapse. This force will retaliate and swallow the painter in an instant!

The attributes, combat methods, and combat characteristics of a magic weapon all come from this magic circle drawn on the magic weapon.

Second: Excellent soul.

If a magic weapon wants to truly exert its own power of independent combat and then let it fight on its own, it must be filled with souls. It can be the soul of a monster, the soul of a demon, the soul of a human, or even the soul of an immortal and a demon.

Different souls and magic weapons have different abilities and personalities. The more powerful the soul is, after being poured into the magic weapons, the more powerful the character of this magic weapon becomes.

Therefore, the power, intelligence, agility, speed, and even stupidity of the soul will be passed on to this magic weapon.

Third: The best spiritual crystal!

For a top magic weapon, even if it has a perfect magic array pattern and is filled with excellent souls, if it is not matched with the best spirit crystal, it is just a defective product that lacks the upper limit.

The drawing of magic circle patterns determines the lower limit of the magic weapon, and the infusion of soul determines the quality of the magic weapon. What really determines the upper limit of a magic weapon is the spiritual crystal it inlaid.

This spiritual crystal not only requires it to be large and can store enough magic power and true energy, but also requires it to be bright enough. Only a sufficiently bright spiritual crystal itself is high enough to withstand the infusion of the powerful true energy and magic power of the great practitioners. Otherwise, once the spiritual crystal of ordinary quality and great practitioners are filled with magic power, it will break open.

Li Chengfeng remembered the spiritual crystal used by Mr. Chen from the Zangjian Pavilion, and he couldn't help but sigh: "It would be great if that spiritual crystal was not broken!"

Su Yuehan suddenly said: "If Master Chen can find it, it means that there must be such a large spiritual crystal here. If we look for it again, we may find it!"

Li Chengfeng was excited and said, "What he said is reasonable!"

The two of them rested for a while and were looking around, but the cave was full of shiny spirit crystals, which only dazzled them and was dizzy. After searching for several rounds, they didn't see a piece of spirit crystal the size of an egg, let alone the size of a pea egg.

Li Chengfeng turned around a few times and dug several pieces of spiritual crystals. He was so tired that his whole body was sweating. The wounds on his body were as painful as a knife. Some of the wounds on his body collapsed and blood flowed out.

Li Chengfeng was so tired that he fell to the ground and looked at the blocked stone cave not far away. He cursed: "It's really a ghost. Are you really going to be trapped in this place?"

Su Yuehan also sat next to Li Chengfeng, looking at him steadily, and thought to himself: If you die like this, you will be carefree.

Li Chengfeng was in a bad mood at this time. He felt something under his butt hurt. He touched it casually, but found a bag containing two squares from his pocket behind him.

The battle was fierce before, and Li Chengfeng didn't notice its existence at all. At this time, he relaxed and felt it hurt his butt when he sat on the ground.

Li Chengfeng poured out the treasure bag, but saw that the "family heirloom treasure" given to him by his father fell out. Li Chengfeng suddenly laughed in anger. He picked up the "Red Zhong" card and printed the blood on his fingers on it.

He vented all his resentment on this mahjong card: "Your uncle, you'll come and make trouble for the young master! Get out of here!"

This sentence reminded Su Yuehan of the two of them falling to the bottom of the valley together, and she couldn't help but smile.

Li Chengfeng glared at him and said angrily: "You dare to laugh at me!" As he said that, Li Chengfeng threw the "Red Zhong" card fiercely at Su Yuehan.

The "Red Middle" card passed by Su Yuehan and rolled and flew in the air. The blood mark on its card was quickly absorbed by the card body. Then the engraving mark on it lit up. When it was about to hit the stone wall, it suddenly emitted a dazzling light.

Boom!!!

With a loud bang, it seemed like a thousand pounds of heavy cannon hit the stone wall, and the stone wall suddenly collapsed into a big hole!

Li Chengfeng and Su Yuehan turned their heads to see them all were stunned!

Damn, what's the plot?!

Li Chengfeng subconsciously picked up the remaining mahjong card that had "get rich". The blood in Li Chengfeng's hand was quickly absorbed by the card body, and then the card body burst into bursts of green light.

Li Chengfeng was surprised and said, "Damn, Dad, you said that's right. This is really a family heirloom!!"
