"Xiaoxiao, do you dare to come down?" Wang Yin looked at the iron centipede in the sky under the water, and squeezed his eyebrows.

Clematis Centipede: If I could speak, I would kill you!

In fact, the water can't hurt the centipede at all, but it just doesn't dare to go into the water, I have to say that this is the difference between people and animals, even if the centipede is powerful, but in the end it is just an animal, and the animal will never go against its own nature.

However, this iron centipede can be regarded as unrelenting, even looking at Wang Yin across the water, and refusing to leave for a moment.

Wang Yin couldn't, so he had to continue in the water, and after about a mile, the water in front of him split into two streams, one continued to flow in the bright place into the distance, and the other turned into a mountain, which seemed to be an underground undercurrent.

Wang Yin pondered, since it was an underground undercurrent, it was likely that there was an underground karst cave, so he immediately walked along this waterway, and finally came to the underground undercurrent, and sneaked in the dark water underground for about half a mile, and finally came to a cave.

The whole cave is very wide, and after going up, I actually found several carved stone chambers.

Wang Yin came to this stone room and found that there were all kinds of tables, chairs, benches, bed cabinets, weapons in this stone room, and even an alchemy furnace and corresponding tools, which seemed to be inhabited.

The top of the cave is inlaid with countless bright night pearls, illuminating the whole space as if it were day, the space in the cave is huge, in addition to the water area of dozens of zhang, there is a wider space is land.

Wang Yin walked around, found no trace of the demon beast, and found no other exits, then sat down and began to heal.

After the healing, I went to look through the books left in this stone room, and I was taken aback, it turned out that this stone room was actually the last place of residence and seclusion of the legendary great master.

It turned out that after the great master was excluded and left that day, he did not go far, but stayed in the vicinity to observe the situation, and what made him depressed was that the situation in the Three Kingdoms was complicated, and it was not at all beyond his control, especially when the world thought that his prediction was just a trick.

People are unkind, but I can't be unjust, the great teacher is not alone, of course, even if he wants to, it is impossible, after all, if the whole world is finished, he will only have a dead end.

So he secretly contacted his diehards and established a cave in the mountains near the ancient city of Sunset for him, and all the access had to pass through the waterway to prevent the invasion of the centipede.

After that, the great master studied the strategy of dealing with the iron line centipede in the cave.

Unfortunately, he never found a feasible solution, and what puzzled him even more was that the will of God seemed to be to let the strangers from the outside world solve this disaster.

However, the Inhuman, who carried countless expectations, just didn't appear, and the great master didn't understand why until he died?

In addition to some of the origins, there are many other things recorded in the books of the great masters, such as alchemy, witchcraft, etc., which is more meaningful to Wang Yin.

After preliminary summarization, Wang Yin found that there were three main parts of the notes left by the great master that were useful to him now, one was the alchemy technique, the second was witchcraft, and the third was the mind power technique.

The alchemy technique records a lot of pills that are very useful for martial cultivation, and even records the refining of the kind of pills that restore spiritual power, of course, this recipe cannot be compared with the simulation in Wang Yin's Heavenly Gate.

And witchcraft is a variety of strange arts, from deceptive tricks to raising Gu worms.

What surprised Wang Yin the most was that this great master was actually a mind master, and judging from the notes, it seemed that the level was not low.

The notes even recorded the fiery red mysterious demon beast in the cave, which the great master called the earth fire eel, and this kind of eel likes to eat the cold ice fruit that grows on the top of this cave, whenever the cold ice fruit is ripe, the ground fire eel will rush to devour it, and once they swallow this fruit, within an hour, if they can cut off a piece of flesh on their back that shines and eat, it is very beneficial to the body, especially for those who practice martial arts.

The notes also pointed out that this place was a place that the Great Master deliberately looked for that was very suitable for alchemy, because below it was a place where the earth and fire activities were very active, and the Great Master also introduced a cold spring, which can be said to be a place where both water and fire are beneficial, and it is naturally a treasure land of wind and fire for alchemy.

After reading all the records, Wang Yin couldn't help but sigh at his luck, this place seemed to be a place of cultivation tailored for him by a great master. There are a lot of alchemy and practice. Could it be that the great master finally calculated that the Inhuman will eventually come to this world, and this Inhuman will definitely be able to discover this treasure land?

Of course, all the answers have been lost in the dust of history.

Looking at the things left behind by the great master, Wang Yin found two Heavenly Hearts, all of which were Mental Power Heavenly Hearts, but with his current level, it was not enough to cultivate.

Some of the other Gu worm eggs have rotted and died, and the weapons have not been maintained for a long time and are in a place full of moisture, so they are all rusted and cannot be used.

As for the official disc documents and the like, they are even more useless to Wang Yin, so they are directly ignored.

With two battles with the Commander-level Cleavage Centipede, Wang Yin knew that the only way he could defeat the Cleavage Centipede now was to desperately squeeze his potential and improve his mental power, otherwise he might be trapped in this underground cave for a long time.

Fortunately, although he was attacked by the commander-level iron wire centipede this time, the medicinal materials collected before were a lot, which was really a loss of infinite eternal space, otherwise Wang Yin would be empty.

Fortunately, the medicinal materials for refining the pill Tianxuan Yishen Pill that strongly restores spiritual power are readily available, as long as Wang Yin is familiar with the refining method of Tianxuan Yishen Pill in Tianmen, there is no problem in refining the pill.

So, let's get started!

In the following days, Wang Yin had been refining the Tianxuan Yishen Pill in the Heavenly Gate.

Ten failures......

Twenty failed ......

Thirty failed ......

The grade of this Heavenly Xuanyi Divine Pill is not very high, but it is also higher than the previous Tongyuan Pill, which is a fifth-level pill.

It is very difficult to refine, and it is thanks to Wang Yin that he has an artifact like Tianmen, otherwise the medicinal materials consumed alone will be enough to make him vomit blood.

After many failures, the training was completely exhausted, and finally refined into one, Wang Yin carefully looked at it: this elixir is not slippery, one end is flat and the other is flat, and there are slight cracks, it looks difficult to see to a certain extent, and even the smell is like baked paste. But for Wang Yin, it was the beginning of success.

continued to work hard, and it was dozens of blows, and then a furnace was opened, and there was actually a pale cyan finished pill, and then Wang Yin's luck began to improve, and his skills became more and more proficient.

However, Wang Yin still did not use the real alchemy furnace to carry out real alchemy, firstly, because his eyes were to directly refine the high-quality pill, and secondly, because the consumption of this pill in the future must be huge, even if this medicinal material is all over the mountains, but it can't afford to waste it many times, so try to save a little if you can save a little.

"The body of the pill is muddy/round, green and transparent, and the smell is refreshing, this is the high-quality elixir, and it has finally become!" After a few more days of torment, Wang Yin finally refined the elixir that satisfied him in the Heavenly Gate.

According to what happened to the spirit element last time, Wang Yin can be sure that the creator of this Tianmen has set a very high standard, if it can be called a fine product in Tianmen, it is a treasure in reality, a treasure in Tianmen, and it may even be the best in reality.

Now that the boutique has been completed, the time has come to open the furnace to refine the real elixir.

Wang Yin had the Vajra Bisha Furnace in his hand, and this great master also left an alchemy weapon called Jinyang Xuantie Furnace, so Wang Yin used the furnace left by this great master to start alchemy directly, and also saved some debugging.

With thousands of simulations in the Heavenly Gate, Wang Yin was very skilled in completing the refining of a furnace of pills, and a furnace of nine pills, each of which was a high-quality pill with a muddy/round, emerald green and transparent body.

Wang Yin twisted one and put it in front of his eyes, just the smell made people feel refreshed.

It has been said in the notes of Youranke before, mental power is like human energy, and the mental power consumed is equivalent to three days and three nights without sleeping, and restoring mental power is equivalent to recovering energy after sleeping, of course, due to individual differences, everyone needs to sleep for a different time, but in any case, they need to sleep, and the effect of this day Xuanyi Divine Pill is very obvious, that is, the time for people to sleep is greatly reduced.

Sure enough, after Wang Yin took the Tianxuan Yishen Pill, the originally dry mental power seemed to have encountered a small river of spring rain, and gradually the river water recovered at a speed visible to the human eye.
