In the following days, Zhou Huan would spend two or three hours every day to inject true qi into the various symbols on the gourd, and the rest of the time would be spent running the cultivation method.

Because the spirit stone is already empty, it can only absorb the spiritual energy that is scarce in the mining area to cultivate. If you look at the previous cultivation efficiency, ordinary meditation may not improve much in a few months. But with this layer of gourd ash liquid, the cultivation can be regarded as a lot better.

Four months later, on the first day of the first month, Zhou Huan stretched his waist, hung a gourd on his waist, and walked out of the door.

This month, it was his turn to supervise the mining in the mining area, so he did not continue to tinker with the gourd in the house. Although Zhou Huan was still in the third layer of qi refining, he obviously felt that his cultivation had risen a bit, and he was about not far from the middle of the third layer.

In the past four months, in addition to the time spent cultivating, Zhou Huan basically spent the rest of his time tinkering with the gourd, and absorbed two drops of ash liquid from the gourd.

For the ash liquid, Zhou Huan made some new discoveries, the more ash liquid absorbed, the more ash gas in the dantian will be, and the rotation speed will also increase.

At this time, the small cloud of gray qi in the center of the dantian was much larger than before, and the rotation speed of the entire true qi cyclone was also a little faster. Zhou Huan speculated that if he continued to absorb the ash liquid like this, even if he had the talent of the five spirit roots, he might be able to slowly catch up with the cultivation speed of the three spirit roots, and even the monks with better talents.

Having said that, Zhou Huan hasn't figured out what the gray gas is. However, Zhou Huan felt that there should not be too much risk, after all, the ash liquid was caused by his own true qi urging the gourd to make it change.

Taking a step back, with the benefits that gray qi is bringing to him now, Zhou Huan doesn't want to delve into this issue. After all, according to the secular world, he is now at the age of a weak crown, and he does not have a deep foundation in cultivation, so he can only wait for the task to return to the sect after returning to the sect, and go to the Thousand Law Hall of Xuanji Peak to check the books and see if he can find some clues.

Not long after Zhou Huan sat down in the courtyard, a mortal miner supervisor ran up the hill out of breath.

After a while, he came to Zhou Huan's eyes, this person's name is Zhao Tieniu, who is dedicated to his duties in the mining area, in recent years, most of them have come to Xiaoyanfeng to report the daily situation in the mining area. Seeing his somewhat nervous look at this time, Zhou Huan knew that there must be some emergency in the mining area.

"Immortal Master Zhou, it's not good, a few more iron-devouring rats have gnawed red iron into the mine." Zhao Tieniu said a little anxiously.

"Steward Zhao is not in a hurry, I'll deal with this matter, where are those iron devouring rats now?" Zhou Huan said with a really like this.

"It's in Cave 15 to the north." Zhao Tieniu replied.

"Let's go now, then." As he spoke, he went to the mine with Zhao Tieniu.

The Iron Eater Rat is a first-order demon beast that is dark black when it is young, feeds on all kinds of weak creatures underground, and likes to devour ores such as gold and iron. Adult iron-eating rats will have different colors of fur because of the different gold and iron they swallow, and their strength is relatively weak among first-order demon beasts.

Not long after following Zhao Tieniu, Zhou Huan came to the entrance of the No. 15 mine in the north.

"You wait outside first, I'll go in and deal with it." After speaking, Zhou Huan took out the red iron sword distributed by the sect from the storage bag, held the sword in his right hand, took the torch in Zhao Tieniu's hand with his left hand, and walked in.

After a while, Zhou Huan walked hundreds of meters into the mine, and a squeaky sound gradually grew in his ears. After another corner, Zhou Huan saw a big hole gnawed open by iron rats on the left side of the front of the mine, and in front of the big hole, there were several iron rats squeaking.

The iron-eating rats in this part of the Nanqing Mining Area often eat the hematite here, and their body surface shows the color of red and black. Or because of the abundance of ores, there are often monsters that gnaw and gnaw into the mines.

Regarding the demon beast of the Iron Devouring Rat, Zhou Huan has also dealt with it a few times in the past few years, and there are still a few rat skins in the storage bag.

Transporting the golden swordsmanship, Zhou Huan walked over lightly, counted the number of iron devouring rats, and sighed that the number of iron devouring rats this time was really considerable, and he could collect a few furs, and he was just about to kill them, but he faintly found that something was wrong.

"Iron rats have always liked to be alone, how can they get together in such numbers?" Zhou Huan thought that there seemed to be a sense of fear in listening to this squeak, and he was secretly vigilant in his heart.

Suddenly, an object suddenly appeared in the shadows, attacking behind, only to hear a ding, Zhou Huan raised his sword to block it, took a few steps back, glanced at the rear, and found that the iron-devouring rats ran deeper into the mine, so he ignored them and confronted the thing in front of him.

I saw that a few feet away from Zhou Huan, a big snake was half-standing with the body of the snake, staring at him with blood-red eyes, and making a hissing sound from time to time.

Zhou Huan looked at it all red, and there were multiple yellow rings on its body, and secretly said that it was not good, how could he meet the red snake here.

The Red Snake is a second-order demon beast, with a fire attribute, usually living in the hot valley woods, with hard scales all over its body, and fire poison in the snake's teeth, the strongest of which is comparable to a sixth-order Qi refining monk.

"Today's fortune is really bad, think of a way to go out first, return to Senior Brother Zhan, and let him deal with this thing." Zhou Huan calmed down and thought about it, and then his eyes began to look around to see if there were any other ways to get out.

After a stalemate for a while, Zhou Huan found that there was no fork in the road near this mine, and the Red Snake did not continue to take the initiative to attack, and he didn't feel a little puzzled, it stands to reason that the second-order demon beast also has the strength of about the fourth layer of qi refining, how can it be so.

Seeing that the big snake was still staring at him and refused to let the road open, Zhou Huan was ready to take a risk, and immediately attached the water attribute aura to the red iron sword and stabbed at the big snake.

Ding ding, a burst of sound came, and Zhou Huan took the sword and fought with the red snake.

The light blue sword light kept flashing around the big snake, and the scales of the red snake drew shallow marks, but even so, there was still no way to cause much damage to the red snake.

But during the battle, Zhou Huan was a little surprised to find that compared to the Terran monks, the breath of the big snake was only a little higher than Fang Zheng, and he suddenly had some confidence.

After a quarter of the incense, the long sword in Zhou Huan's hand began to gradually appear some cracks, obviously unable to support it. At this time, the big snake that had been moving unfast suddenly opened its bloody mouth and bit towards Zhou Huan. There was only a click, and the red iron sword used to block was bitten off by the teeth of the great snake.

"Not good." Zhou Huan had no weapon in his hand at this time, although the effect should not be good, he could only urge the golden sword technique to resist the enemy.

Seeing that the red snake opened its mouth again and was about to bite it again, in a hurry, Zhou Huan untied the gourd on his waist and prepared to use the gourd to resist the attack of the red snake.

With a click, Zhou Huan stuck the big mouth and fangs of the red snake with his left hand against the gourd, and then urged the golden sword technique to shoot seven inches.

The serpent was a little painful and began to writhe violently. As soon as he picked up the second golden sword, he saw that the gourd was about to be unable to jam the big snake's mouth.

At the critical moment, a wave of stubbornness surged up, Zhou Huan used all his strength to activate the metallic true qi in his body, and even mobilized part of the small cloud of gray qi, and the golden true qi small sword before the tip of his right finger suddenly became larger, and a five-colored light emanated from it. Ignoring the changes at this time, Zhou Huan stimulated his swordsmanship and shot over.

Picking up the gourd and sitting against the wall of the mine, Zhou Huan let out a sigh of relief. Then he took out the healing medicine in the storage bag and swallowed it, and the bleeding gradually stopped from the many wounds on his body, and he laughed a little proudly when he looked at the corpse of the big snake not far in front of him.

"It turns out that I can also have this divine power, it's really cool." The young Zhou Huan killed a strong enemy for the first time, and this situation swept away some of the haze in his heart for many years.

After resting for a while, Zhou Huan stood up and walked to the corpse of the big snake. Looking at the seven-inch position that was completely pierced, Zhou Huan recalled the scene just now, and was a little afraid and a little sighing, if it weren't for the last moment, through the golden swordsmanship blessed by gray qi, I am afraid that now the blessing and misfortune will be unpredictable.

Then he began to clean up the battlefield, and the materials that Zhou Huan felt were valuable to the corpse of the Red Snake, and he put it away, ready to exchange it for spirit stones when he went to Fang City.

After disposing of the corpse of the big snake, Zhou Huan stood up and began to look around, trying to find out what attracted the red snake, after all, according to its habits, it should not come here.

Walking to the hole that had been gnawed open by the iron rat, he looked inside, and there were two pale red objects glowing not far from the cave.
