Chen Zhiyuan listened to Mo He's suggestion and brought an extra piece of clothing into the Han Silkworm Cave, only to know that what Mo He said was indeed right, the cave was particularly cold, cold from the inside out, and the clothes had no effect at all.

Anyway, there was no one here, so Chen Zhiyuan didn't care so much, and quickly took out a piece of clothing from the storage bag, which was the one he had touched from Jin Dan before, and now that he put it on, he felt much better.

There is only one entrance to the Han Silkworm Cave, but there are many forks in the road, but fortunately there are signboards, and there will be a luminous stone on the wall every short distance, so you can see the inside clearly, at least not to get lost.

Chen Zhiyuan wanted to steal two luminous stones to play, but thinking that these luminous stones were all connected into a formation, one would be discovered if something went wrong, and the luminous stone was not a night pearl, so it was not very valuable, so he gave up after thinking about it.

Carrying the pickaxe he received at the entrance of the cave, this pickaxe was also a magic weapon, covered with various runes, and it was also very heavy, Chen Zhiyuan began to march towards the Han Silkworm Cave with a cat's waist.

The word "someone" was pasted on the signage in front of many forks, and Chen Zhiyuan knew that this was the end of this fork in the road, and there was no need for him to run in and grab it with others.

Slowly groping in the hole, slowly going deeper and deeper, Chen Zhiyuan finally found a pit where no one was around, and hurriedly pasted the word "someone" on the signboard at the population department, so that he could dig with peace of mind and not worry about someone running in and disturbing him.

The pickaxe hits the stone wall with a "ding" sound, but there are not many stones that can be knocked down.

Chen Zhiyuan somewhat understands why the pickaxe used for mining has to be made into magic weapons, this mine is not easy to dig! Chen Zhiyuan's hands are numb now, and he still hasn't seen any shadow of the iron ore, and the stones are only knocked down a few big fists, and when he touches them with his hands, Chen Zhiyuan feels that he is touching the ice cubes, not the stones.

No wonder Mo He said that if he couldn't stand it, he would change to something else, and now this situation is that it is difficult to work hard.

However, Chen Zhiyuan is not a person who gives up easily, after all, he has nothing to choose except for mining now.

The pickaxe is not powerful, Chen Zhiyuan has other ways. Chen Zhiyuan took out a long sword of good quality from the storage bag, tried the feel, and it was not bad, so Chen Zhiyuan used the long sword to slam it against the stone wall.

The effect of good things is different, the stones that are difficult to knock with a pickaxe are much easier to hit with a long sword, but the spiritual power consumption is a little larger.

It is estimated that there are not many people who are as extravagant as Chen Zhiyuan, using weapons to mine, or weapons in the condensation period, if they are known by other scattered cultivators, they will not be angry.

The distribution of the dark iron ore is not very regular, Chen Zhiyuan knocked down the stone wall with a long sword, but he couldn't knock a few pieces of dark iron ore.

Sometimes I see a piece of iron ore exposed, but when I knock it out, I find that it is just a thin layer of iron ore skin wrapped around the stone, and sometimes it is just a stone, and after accidentally breaking it, all that is exposed inside is black iron ore. This greatly increased Chen Zhiyuan's workload, in order to prevent the dark iron ore hidden in the stone from slipping through the net, Chen Zhiyuan had to break it every time he knocked down a stone to check it.

Mining is not an easy job, in less than half an hour, Chen Zhiyuan's spiritual power and strength are exhausted, and he has no choice but to stop and rest. After weighing the iron ore that has been dug up, there are not many, only about ten catties, but there are a lot of stones, all of which are more than two hundred catties.

Originally, Chen Zhiyuan wanted to use the food qi method to restore his spiritual power, but thinking about where he got two new exercises from the old students, although Chen Zhiyuan felt that it was impossible to achieve three in one, but it was not a loss to practice both, and he practiced the food qi method every day, Chen Zhiyuan also wanted to try other exercises.

Chen Zhiyuan took out the two exercises and looked at them carefully, and then compared the food qi method he practiced, and felt that the difference was not very big, no wonder it was said that it was split from the same book, because the difference between the three of them was only the operation of a few relatively fine meridians.

After comparison, Chen Zhiyuan finally chose the "Qi Replenishment Method" to cultivate first. Because according to the descriptions of these three exercises, the "Qi Replenishing Method" pays more attention to the recovery of spiritual power, while the "Qi Absorption Method" focuses on the storage of spiritual power, and the "Qi Eating Method" focuses on the absorption of spiritual power.

Therefore, Chen Zhiyuan is now running out of spiritual power, and the best choice to recover spiritual power is the "Qi Replenishment Method".

The first time he practiced the "Qi Replenishment Method", Chen Zhiyuan did not have too many obscurities, because it was too similar to the "Qi Eating Method", and it was enough to adjust the operation route of spiritual power a little.

Chen Zhiyuan could clearly feel that with the operation of the exercises, the spiritual power in his body had indeed recovered much faster, compared to the "Qi Eating Method", it was about one-tenth faster.

However, with Chen Zhiyuan's cultivation, where he was not paying attention, a trace of cold qi in the Han Silkworm Cave began to slowly mix into the free spiritual energy absorbed by Chen Zhiyuan with the operation of the spiritual power in Chen Zhiyuan's body.

"Hiss......"

Chen Zhiyuan was woken up by pain all of a sudden, after all, the meridians are relatively fragile places, and although there is not much cold qi, it is like cutting meat on the body with a knife in the meridians. At first, the feeling was not so obvious, Chen Zhiyuan thought that this was the characteristic of the exercise, but as the spiritual power flowed to the meeting point, the two cold qi were not controlled at all, and there was a direct hedge, and Chen Zhiyuan's meridians suddenly seemed to have been twisted with a meat grinder.

The pain is still there, but when Chen Zhiyuan went to check it again, he didn't find any problems with his body, well, except for being a little tired, it seems that this is a side effect of the "Qi Replenishment Method".

Half of his spiritual power had recovered, and since he hadn't checked out any problems, Chen Zhiyuan felt that it would be good to endure it, how could he have so much thought to think about it now? So Chen Zhiyuan endured the pain of being attacked by the cold and continued to cultivate.

At the end of the day, although Chen Zhiyuan used a long sword to mine, there didn't seem to be much difference in the results, although he dug fast, but the number of times he needed to recover his spiritual power also increased, so Chen Zhiyuan only dug more than sixty catties of dark iron ore this day.

handed over the pickaxe and the iron ore, poured out the gravel brought out, and received a sign to register his quantity, Chen Zhiyuan dragged his tired body back.

For three days in a row, Chen Zhiyuan dug 200 catties of black iron ore and exchanged it for two gold leaves, but he couldn't stand it, and on the fourth day, he lay in bed and was not ready to go out.

Originally, mining was very tiring, and the practice of "Qi Replenishment Method" was tired and tired, coupled with the invasion of cold air, Chen Zhiyuan felt that he was a lot haggard in just three days.

Looking at this wrinkled hand, there are still a few chilblains on it, Chen Zhiyuan feels that it is so difficult.

But no matter how difficult it is, life still has to go on. Although the invasion of the cold made the tiles very uncomfortable, after recovering, Chen Zhiyuan felt that his meridians were more resilient than before.

After resting for two days, Chen Zhiyuan crawled back to the mine to mine, but this time Chen Zhiyuan dug with a pickaxe. Although the pickaxe is laborious to dig, it can last for a long time, and the body will warm up after digging for a long time, which is much more comfortable than digging with a long sword.

The reason why the Han Silkworm Cave is called the Han Silkworm Cave is that in addition to the fact that it is very cold inside, it is also thought that there are indeed cold silkworms in it, and this cold is also caused by cold silkworms.

Chen Zhiyuan met a cold silkworm when he was mining today.

It was a crystal clear ice cube, when Chen Zhiyuan knocked on the stone on its appearance, the temperature in the mine suddenly dropped a lot, fortunately, the equipment on Chen Zhiyuan's body was not bad, it was all magic weapons, and it had the effect of constant temperature, but it was not so comfortable when the face and hands were exposed, after all, the gloves were resistant to high temperature and not freezing.

The cold silkworm is as thick as Chen Zhiyuan's thumb, and it is coiled up in the ice cube, which is the size of a fist.

Chen Zhiyuan remembered that the people in the place where they received pickaxes and registered in front of the mine were all buying silkworms, and each one had a price of ten gold. However, Chen Zhiyuan didn't plan to sell this cold silkworm.

It is said in the "Hundred Things" that the cold silkworm can increase the body's ability to resist cold. Although Chen Zhiyuan doesn't know how much it will be raised, judging from its price, it won't be too much anyway.

Chen Zhiyuan is not a person who is short of money now, so he will definitely not sell this silkworm.

The black needles that had not been used for many days were finally reused. Chen Zhiyuan carefully removed the ice cubes covering it little by little, and exposed the cold silkworms hidden inside.

The silkworm felt the movement, its body began to move slowly, and the surface of the body began to secrete some viscous and clear liquid, and soon a thin layer of ice began to cover the body of the silkworm.

Chen Zhiyuan naturally will not do what he wants. Chen Zhiyuan quickly pinched the head of the Han Silkworm, grabbed the body of the Han Silkworm with his hand, and pulled it hard, the head of the Han Silkworm was separated from the body, and some indescribable things were brought out.

The cleaned silkworm can be eaten directly, or other ingredients can be added to make food to enhance its taste and effect. Chen Zhiyuan has no conditions now, so he chooses to eat directly.

The palate has a bouncy texture, and the bite is like chewing on a chewy piece of ice. The strange taste he imagined did not appear, and until he finished eating, Chen Zhiyuan only felt that he had eaten a chewy ice cube.

Such a good food, after eating, it must be absorbed by the "Food and Gas Law" to be cost-effective.

After running the exercises, the cold silkworm in his stomach was quickly digested, and Chen Zhiyuan could faintly feel that the spiritual power in his body seemed to be mixed with something different, but it was very weak, and he couldn't feel it clearly now.

It seems that you have to eat a few more to have an effect! Chen Zhiyuan clenched the pickaxe in his hand, his eyes gradually became firm, his body gradually began to be full of energy, and the previous fatigue was also swept away, and he began to knock the stone wall.

I'm a cold silkworm killer with such feelings, and if I meet a cold silkworm in the future, either you die or I die!
