Li Chengfeng thought of a way to get out, he had always been a person who didn't believe in evil, so he didn't believe that he would be trapped here and couldn't get out.

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

But within this range, Li Chengfeng couldn't detect any trace of grass and wood spiritual power, which made him unable to borrow even if he wanted to.

This is also the biggest drawback of Li Chengfeng's set of exercises: relying too much on the surrounding environment!

After Li Chengfeng tried to search again, he looked at Su Yuehan with some frustration when he found nothing, and he asked tentatively, "Do you have a way?"

Su Yuehan shook her head bitterly.

Li Chengfeng didn't ask the bottom of the question, he said: "Then, now find a spirit crystal embedded in the Sky-Breaking Sword, can you make the Sky-Breaking Sword recover its mana?"

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

Li Chengfeng immediately dug down a piece of spirit crystal and put this spirit crystal into the groove of the Sky Breaking Sword, but this spirit crystal is only the size of a human thumb, and the groove is the size of a goose egg.

Li Chengfeng angrily threw this piece of spirit crystal out far away, and then he began to look around for a larger spirit crystal, but Li Chengfeng looked around, and the largest of these spirit crystals was slightly larger than his thumb, which did not meet the spirit crystals needed by the Sky Breaking Sword at all.

Su Yuehan smiled bitterly: "This spirit crystal the size of a goose egg is worth as much as a high-grade magic weapon. All the top magic weapons in the world, the spirit crystals inlaid on them are all of this size, if it is so easy to find, then the top magic weapons are worthless. ”

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

This kind of craftsmanship does not refer to the work of a blacksmith, but to the pattern circle engraved on the magic weapon.

This ultra-small circle is extremely complex and sophisticated, and the drawer must be a person who is extremely proficient in the study of the circle, and at the same time has extremely advanced mana cultivation.

When drawing a circle, it's like a person manipulating a huge force and then branding it little by little in a certain place, the bigger the place, the less difficult it is to draw, because the gap between the patterns is also larger.

And the smaller the place, the less difficult it is to draw, because the gap between the patterns is also smaller. Once the two patterns touch each other when drawn, the circle will immediately collapse, and this force will come out and devour the painter in an instant!

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

Second: the best soul.

If a magic weapon wants to really exert the power of independent combat, and then let it fight on its own, it must be infused with the soul, which can be the soul of monsters, the soul of demons, the soul of humans, and even the soul of immortals and demons.

The soul is different, the ability and character of the magic weapon are also different, the more fierce the soul before death, after being poured into the magic weapon, the more fierce the character of this magic weapon will be.

Therefore, the spirit's own strength, intelligence, agility, swiftness, and even stupidity will be inherited from this magic weapon.

Third: the best spirit crystal!

For a top-level magic weapon, even if there is a perfect magic circle pattern and an excellent soul is infused, if there is no top-quality spirit crystal matching, it is just a defective product that lacks an upper limit.

The drawing of the magic circle pattern determines the lower limit of the magic weapon, the infusion of the soul determines the quality of the magic weapon, and what really determines the upper limit of the power of a magic weapon is the spirit crystal it is inlaid with it.

This piece of spirit crystal not only needs to be large and can store enough mana true element, but it also needs to be bright enough, only the spirit crystal itself is strong enough to withstand the infusion of the powerful true yuan mana of the great cultivator, otherwise the spirit crystal of ordinary quality, as soon as the mana of the great cultivator is poured out, it will be shattered.

Li Chengfeng thought of the piece of spirit crystal used by Master Chen of the Hidden Sword Pavilion, and he couldn't help but sigh: "If only that piece of spirit crystal hadn't been broken!"

Su Yuehan suddenly said: "This Master Chen can find it, which means that there must be such a big spirit crystal here, let's look for it again, maybe we can find it!"

Li Chengfeng's spirits perked up, and he said: "What you say is reasonable!"

The two of them rested for a moment, and searched around, but the stone cave was full of shiny spirit crystals, and they were only dazzled and dizzy, and after looking for several times, they didn't see a single spirit crystal the size of an egg, let alone the size of a goose egg.

Li Chengfeng turned around a few times and dug up several pieces of spirit crystals, only to sweat all over his body, the wounds on his body were painful like knives, some of the wounds on his body collapsed, and blood flowed out.

Li Chengfeng was so tired that he couldn't look like it, he sat on the ground with his buttocks, looking at the blocked stone cave not far away, he scolded: "What a hell, do you really want to be trapped in this place?"

Su Yuehan also sat beside Li Chengfeng, looked at him fixedly, and said secretly in her heart: If you die like this, you will be carefree.

Li Chengfeng was in an irritable mood at this time, he felt that something under his buttocks was in pain, so he touched it casually, but he found a bag containing two cubes from his back pocket.

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

Li Chengfeng poured out the bag, but saw that the "heirloom" given to him by his father fell out, Li Chengfeng suddenly laughed angrily, he picked up the "Hongzhong" card in it, and the blood on his finger was printed on it.

He vented all his anger on this mahjong card: "Your uncle, at this time, you will still come to block the young master!

This sentence reminded Su Yuehan of when the two fell to the bottom together, and she couldn't help but smile slightly.

Li Chengfeng glared and feigned anger: "You actually dare to laugh at me!" As he spoke, Li Chengfeng threw the "Red in the Red" card viciously towards Su Yuehan's side.

This "red" card swept past Su Yuehan, rolling and dancing in the air, but the blood mark on its card body was quickly absorbed by the card body, and then the engraved mark on it lit up, and when it was about to hit the stone wall, it suddenly emitted a burst of dazzling light.

Bang!!!

There was a loud bang, as if a thousand pounds of heavy artillery hit the stone wall, and suddenly the stone wall collapsed into a big hole!

Li Chengfeng and Su Yuehan, who turned her head to look, were all dumbfounded!

Damn, what kind of plot is this!!

Li Chengfeng subconsciously immediately picked up the remaining piece of "fortune" mahjong tiles, and the blood stains in Li Chengfeng's hands were quickly absorbed by the card body, and then the card body bloomed with bursts of blue light.

Li Chengfeng was pleasantly surprised: "Dad, Dad, you're right, this is really a family heirloom!!"
