The twilight dissipated, and the heavens and the earth returned to darkness.

After eating the spiritual rice and returning to the mine, Lin Mu heard a burst of excited shouts before he saw the spirit attendants.

"Hurry! keep fixing it, Lin Tou will come back in a while, and then you will be able to see the power of his swordsmanship!"

"Do you really think of him as a human monk? I heard that he is a python spirit, and this day I saw him swinging his sword intermittently, he must be a monster specializing in demon body cultivation!"

"Shhhh

......

There was a lot of noise, and there were screams from time to time, Lin Mu's heart tightened, and he hurriedly entered the cave where the spirit servant was mining.

In front of him, twenty spirit attendants stood excitedly on the side, and a few people in front of them, one by one, held spirit runes, excitedly looking at the place in front of them where thorns were intertwined.

With a "cluck" grinding sound, the thorn mass broke a hole, and a mouse the size of a kitten came out, Mu Yong laughed, and the spirit rune in his hand flew out, flying to the mouse like having eyes, and in the blink of an eye, another thorn was intertwined, tightly entangled around the giant rat.

However, this giant rat was gray and black, almost the same color as the surrounding stone walls, and the sharp thorns on the thorns pierced its body, and it was unharmed, and its defense was really good.

"Haha, it's Lin Tou who is back! With this iron-eating rat handed in, and then find its nest, in addition to the consumption of changing spirit talismans, we can get an extra fifty yuan per person this month!"

"An iron-eating beast is one or two silver, which is our price, and Lin Tou handed it over, it must be another price, only high, not low!"

There was a burst of excited discussions, and the tired expressions in the day disappeared completely, as if they were happy and excited for the New Year.

Seeing that the Thorn Spirit Rune could still support for a while, Mu Yong explained to Lin Mu.

It turns out that between the spiritual veins of the underground, it is not a barren, those ordinary grass, wood, snakes and insects have been immersed in the spiritual energy for a long time, and after a long time, they have unconsciously mutated, and after several generations of reproduction, from the mortal to the spirit, they are no different from the spirit animals.

However, this kind of underground spirit snake spirit rat has not grown much in spiritual wisdom and ordinary snakes and rats, and it is not like a demon cultivator to practice qi, but its body is strong, like iron and stone.

This kind of iron-eating rat is the most common mutated spirit animal in the mine, feeding on iron and stone, with muscles all over the body, like pig iron, sharp teeth and claws, but it is very small and not aggressive.

The spirit attendants have long been familiar with this kind of thing, and the thorn spirit runes issued by the sect are specially made for these demon beasts.

This kind of underground demon beast, with strong muscles and extremely chewy heads, has lived in the spiritual veins with rich spiritual energy for a long time, and is more spiritual power than red spiritual rice, and it is also easy to absorb.

Every time the spirit attendants encounter iron-eating rats, as long as they have no casualties, they can be caught by the guards and handed in, they can get one or two pieces of silver, fifty yuan per person, enough for the family to eat for five or six days.

What's even more gratifying is that this kind of iron-eating rat likes to take the place where the aura and iron are strong as its nest, as long as you dig along the rat hole, you can find more locations of the spirit stone.

At that time, whether it is a spirit stone or a refined iron, the harvest can be greatly improved.

Lin Yong said with a smile after explaining: "Lin Tou is really a big demon with luck, on the first day he came to the mine, he took everyone to harvest such a gift, and then it depends on Lin Tou's means!"

Lin Mu was curious about this underground demon beast, and didn't want to kill it with the dragon snake sword, so he took a few steps forward, and seeing that the thorn mass was bitten by it again, he reached out with his right hand, easily grabbed the back of its neck and brought it to his front.

The iron-eating rat struggled for a while, and its iron-like body was extremely strong, almost like the bite of a wolfdog.

But with Lin Mu's current strength, how can it turn the world upside down!

With a little effort, although it was under the outer body, the demon python itself couldn't use five or six points, but it had already pinched this little thing that was struggling violently, and it was honestly hung between Lin Mu's three fingers.

Especially when Lin Mu's spiritual power was running, it felt the smell of the natural enemy snake python on Lin Mu's body, and it was like a thunderous toad, and his whole body was weak.

"This rat has such hard skin!"

With half of Lin Mu's strength now, it is a piece of solid wood, and he can pinch out two fingerprints with his bare hands, but this iron-eating rat is unharmed!

Throwing his hand into the air, Lin Mu's iron sword slashed a sword flower and pointed at the iron-eating rat.

The swordsmanship collapsed, and with the advantage of the iron sword, when the tip of the sword reached the body, the iron-eating rat was covered by the waist of the sword with a little red scar, and when it fell to the ground, it was already lifeless.

Although the scar was small, the force of the collapse had shattered the internal organs in its chest.

Although it feeds on iron and its skin and flesh are hard, after all, it is the flesh and blood of an ordinary demon beast, how can it be hit by Lin Mu.

Mu Yong put away the carcass of the iron-eating rat, and the group continued to mine, but Mu Yong took ten people and dug straight to the rat hole drilled by the iron-eating rat.

"Hehe, this iron-eating rat is naturally at ease, and the walking range of foraging will not exceed three feet of the nest, and it can be dug in a day at most. Seeing that Lin Mu was puzzled, Mu Yong explained carefully.

Lin Mu was quite interested in this kind of digging and treasure hunting, and seeing that they were digging slowly, he let everyone dodge a little.

The fine iron sword only stabbed with mortal force, and only scratched shallow scars on the stone wall, but Lin Mu only poured a trace of spiritual power, and the blade of the sword was like a blunt sword, easily piercing an inch.

The spiritual power continued to pour in, and when he felt that the iron sword could no longer withstand more spiritual power, Lin Mu stabbed the sword in his right hand and stabbed towards the stone wall!

The long sword entered the wall, until the hilt of the sword, Lin Mu bent his arm and rolled, the spiritual power vibrate, only to hear the rumbling sound inside the stone wall, and a round stone strip was taken out of the stone wall by Lin Mu, who retreated with the momentum.

At the crack of the stone wall, from time to time you can see a little bit of spirit stone brilliance falling on the gap, and several spirit stones have been cut in two.

All the spirit servants were stunned, they saw that when Lin Mu practiced swords, he even did a very reluctant way to swing the sword, and thought that Lin Mu was a demon body, like those monsters, he didn't understand human swordsmanship, and a few people with dark hearts secretly laughed at Lin Mu, who was a demon clan, and Lin Mu, who had low intelligence, wanted to learn human swordsmanship.

Just now Lin Mu stabbed the wall with a sword, and these people laughed secretly in their hearts, how could anyone use a sword to dig a stone wall?

It's just that the magic of cultivating the Dao is not something they can understand after all, if the spiritual power of practicing Qi can only increase some strength, where can they practice Qi to build a foundation and become the fundamental medium of the immortals!

Breaking the wall with a sword is just because Lin Mu has long discovered that whether it is the spiritual power of a monk or the power of a martial artist like Lan Tianhe in this world, it is by no means the weak appearance of the internal force seen in his novels in his previous life.

Wang Chongyang, who was at the peak of the Five Absolute Peaks of the Central Plains, was so shocked to see that Lin Chaoying was secretly plotting and writing with his fingers on the stone wall; Xiao Feng made a "dragon capture skill" in the apricot forest, so he shook the tiger, shook the storm and shook his voice, and made Wang Yuyan's frightened flower look pale, unable to say a word, secretly thinking that his cousin's capital was much worse than the big man in front of him.

But the spiritual power of this world is far stronger than mortals can imagine, it is Li Tianyi, who was defeated under Lin Mu, but the fourth layer of qi training, its strength is so terrifying, when the spirit rune is enough, it is enough to wipe out a team of elite soldiers on the battlefield who have never practiced qi.
