The spiritual power was injected into the sword, and the speed at which Lin Mu excavated the stone wall far exceeded that of the spirit attendant.

One sword turned, it was jerky at first, and after more than ten swords, Lin Mu found some tricks to break stones with a sword.

"On this stone wall, the spirit stone is the hardest, followed by the stone, and finally the dirt gap between the stones. ”

Although his sword power is heavy now, whether it is a stone or a spirit stone, it can be broken with one blow. But if you can't follow the gap, you will do a lot of useless work invisibly if you enter the gap without thickness.

"If you go down with a sword, just by feeling on the sword, you can bypass the hard spirit stone and stone with the momentum, and the long sword swims in the gap between the stones, wouldn't it invisibly increase the power of the sword technique by several times?

The stone walls are hard and soft, seemingly unbreakable, but in fact there are many easily imperceptible gaps. Isn't that the spirit rune like this? Its defensive light shield relies entirely on the spiritual power in it, one is tough, it is bound to be weak elsewhere, and between the operation of spiritual power, there must be a "gap" in the edge, if you find a flaw between the spiritual power in it, you don't need to use spiritual power, just a sword, you can take the enemy's life!

Let his army of millions be strong, as long as it is not really ironclad, he will definitely be killed by a sharp knife!

Thinking in his heart, his hand did not stop, Lin Mu's long sword was sharpened, and the broken stones were constantly thrown behind him, and the spirit servants behind him were only dazzled.

Digging to two zhang, the wall is densely covered with spirit stones, but it seems that the stones are more obvious.

At the end of the sword and rat hole, I saw a hollow stone pit, connected to a rat path leading to other places, which I thought was the direction that the rat had moved from before.

In the hollow position, it is obviously a place where iron and stone gather, and there are no stones on the stone wall, only black and hard iron ore clothing.

In the middle of the rat's nest, there is a black iron stone the size of a human head.

This is an incomparably pure refined iron ore, which does not need to be quenched, and is a natural casting material.

Lin Mu was a little disappointed by this, and then shook his head with a smile.

It's just an ordinary iron-eating rat, do you still want to dig up an artifact ring where the old man lives?

Mu Yong saw that Lin Mu was not interested in this fine iron, so he took it out, put it aside, and prepared to hand it over to Hefu after work.

"Go on, go back and rest when the time comes, I'll practice my sword here tonight. After the explanation, Lin Mu continued to return to the next mine to practice qi with a sword.

The twenty spirit servants looked at each other, all of them were happy, not only did they catch an iron-eating rat and a piece of refined iron ore today, but more importantly, Lin Mu broke the stone with his sword and dug up these gravels!

As long as it takes a little effort to pick it up, they can take out the spirit stones in it, which is far easier than digging up one shovel at a time on the stone wall.

"Lin Tou is really good, he treats people well, and he is not greedy. It stands to reason that with his identity as a disciple of the Great Demon of the Foundation Building, these strange things dug up by mining, whether they are iron-eating rats or refined iron ore, as long as he wants them, they can be received in his pocket, and the sect will not pursue them. But they just didn't take it, let's hand over this refined iron ore, which is enough for another ten cents per person. A young spirit attendant laughed heartily.

The rest of the spirit attendants, even if they had some other different thoughts in their hearts, would not openly say something different next to Lin Mu.

Back in the mine, Lin Mu continued to practice his sword, not only proficient in spiritual power to run the meridians to enhance the power of sword moves, but also felt the subtle difference between the long sword piercing the stone wall.

Mu Yong came once in the middle, and handed over all the spirit stones he had received today to Lin Mu, a total of two hundred and thirty-one, and after asking Lin Mu to sign it, he went back with all the spirit servants and the refined iron ore.

This situation will continue until Lin Mu harvests 30,000 spirit stones, which is considered an invisible benefit given by the sect to long-term monks, and then although Lin Mu will still stay here for ten months, the spirit stones they collect need to be handed over to the sect.

Under the glowstone light, Lin Mu's sword shadow danced, silent, unmoved by the outside world.

Taiyin aura is different from the sun's aura, only on the fifteenth day of the first month of the month, it will erupt, and the rest of the time, it is so thin that Lin Mu can't feel it at all with Lin Mu's thoughts at this time.

Therefore, Lin Mu spent the night in the mine until the sun rose the next day, and he resumed his life the day before.

Things change and the stars change, and in the blink of an eye, Lin Mu has been in the mine for more than six months, calm and quiet, dedicated to practicing qi and swords, except for occasionally digging up a few iron-eating rats, nothing else has happened.

There are many affairs in the outside world, Bai Yi has come back after the New Year, and he has not seen Lin Mu, so he naturally complains for a while, and he has no intention of coaxing for a while.

Whale Lie originally wanted to summon Lin Mu to join him, and then go to find those well-known Qi Cultivation Demon Cultivators to compete, but Lin Mu was not there, and the other party demon clan was outnumbered, so he had to cultivate honestly.

Demon Zhang Wugu also looked for Lin Mu several times, wanting to discuss swordsmanship, and learned that Lin Mu had come to Fugui Island, a forbidden place in the mine, and ordinary disciples were forbidden to enter, so he did not receive a task in this regard, so he also pressed it first.

Turtle Chan is also like a ghost, wandering in Hefu, but it is somewhat similar to Lin Mu: No matter if the world is turned upside down, I will meditate and practice qi.

The rest, friends, or opponents, are more or less looking for Lin Mu to have something, but Lin Mu is in the mine, avoiding everything, these trivial things that seem to be difficult to refuse and should not be rejected can no longer affect him.

Only ......

"What you said is really true? Then Lin Mu really shouted that my iron-armored giant crab is vulnerable, and sooner or later he will be caught and devoured?!" Under the river waves, the iron-armored giant crab's right claw tightly clamped the vicious movement, and his face was irritable.

Although the evil calamity is the thick-skinned body of a crocodile, how can it withstand the gravity of this qi cultivation demon?

Throwing it casually, the ironclad giant crab screamed angrily, slammed its claws into the water, and headed towards Fugui Island.

The evil calamity calmed down behind him, and when he saw the ferocious momentum of the ironclad crab, he couldn't help laughing.

"Lin Mu, I can't imagine that even the Iron Crab has an enmity with you, God really helps me! I want to see how you are caught in two by the angry Iron Armor Crab!"

Fearing that he would not see the enemy's death, he hurriedly chased after it, although the speed was not as fast as the iron crab, but it still chased with all its might.

Hurrying slowly, I finally arrived at the Soul Picking Palace.

"Gate Guarding Turtle, quickly call Lin Mu to come out! I want to fight him to the death!" The iron-armored giant crab has a violent face, and has turned into a giant cancer demon body, walking left and right, and the bluestone ground is marked by its six-legged stone chips.

The gatekeeper turtle said solemnly: "An existence like yours is no longer something that can be killed casually, Lin Mu is now the only personal disciple of the Moon Protector, how can you be killed in one go?

The ironclad giant crab's dull voice was like a giant drum: "I won't kill him!

Seeing that his words were not heard at all, the turtle guarding the door was also angry.

If you want to fight him, wait for him to come out!"

Evil calamity, his eyes flickered for a while, and he suddenly saw the spirit boy who brought food to Lin Mu on weekdays, and couldn't help but smile, stepped forward, and whispered a few words beside the ironclad giant crab.
