The prepared potion was poured into the container to cool down. Su Xiao picked up the container and looked at the semi-fluid potion. The potion was dark red and had a strong sense of ominousness.

This is a potion prepared using [Old Dragon Essence] as the main material. It was originally going to be called "Dragon Soul Secret Potion", but now, it is more appropriate to call it "Evil Dragon Potion".

The location of [Old Dragon Essence] was provided by the evil heart. It is located in a very dark cave deep in the "Ashes of the End". When the demon spirit incarnate found the old dragon, it had been dead for several years. Dragons of this strength

, within ten years after death, the dragon's blood and soul essence will not decay. This process will only proceed gradually after 16 to 19 years.

Under normal circumstances, before the dragon's blood becomes corrupted, it will attract strange beasts with keen sense of smell to devour it. The extremely dark caves in the "Ashland" have special topography, forming a natural dark ring. This "old dragon essence"

” has only survived to this day.

But when the demon spirit incarnate found the old dragon's corpse, Su Xiao saw through the feedback from the monitoring device that this extremely powerful old dragon's blood was severely corrupted, its dragon skin was pale and rough, and it had long lost its energy.

The boy's hole is particularly turbid.

This is actually not an abnormality. This old dragon must have been seriously injured and hid in the "Ashland" to recuperate. Unexpectedly, he was too seriously injured and died as a result. Considering the cursed environment of this world, the corpses were like this

The changes are not surprising.

This "Old Dragon Essence" has a bonus effect. Direct absorption can permanently increase health by 120,000 points, but it will permanently reduce willpower by 20 points. 20 points of willpower are exchanged for 120,000 health points.

No matter how you look at it, you are making money.

The problem is that the evil heart has predicted the location of this "old dragon spirit", and the evil heart may have noticed that its sworn lord, the scarlet lord, is dead. Under such circumstances, the evil heart will be desperate.

Use any means necessary to break free from Su Xiao.

With the deceit and cunningness of the evil heart, he will definitely not try to escape from Su Xiao in a short period of time, but will plant hidden dangers again and again, such as this "Old Dragon Essence".

Or to put it another way, the evil heart predicts the "supreme life essence" as a junction point. Before this, the evil heart has always been afraid that its sworn lord, the scarlet lord, will come to find it, or that the lord of the past will suddenly pursue it.

Characters, after all, the behavior of alien beings in the void, no one can predict.

With these two threats present, it is a good thing to be restrained by Su Xiao. When the two come, the evil heart plans to hide with Su Xiao and let Su Xiao help it withstand it.

After Su Xiao obtained the "Supreme Life Essence", the Red Lord, the sworn Lord of the Evil Heart, died, and the Lord of the Old Days showed no signs of looking for its small role. In this way, Su Xiao became the Evil Heart and gained freedom.

's number one enemy.

What I have to say is that the selection of this "Old Dragon Essence" is indeed of a high standard. If Su Xiao hadn't pursued the quality of the potion and wanted to eliminate all the debuffs of the "Evil Dragon Potion", he would never have discovered the secrets hidden in this potion.

characteristic.

"Evil Dragon Potion" has a total of five versions. The first version of "Evil Dragon Potion" is:

"Permanently increase the health value by 85,000 points, and permanently reduce the willpower attribute by 1 point."

This made Su Xiao very dissatisfied, not only because the gain was reduced too much, but also because there were still debuffs. Fortunately, the deployment was not completed and could catalyze changes. This is why the second version was created.

"Permanently increase the health value by 100 points, and permanently reduce the willpower attribute by 0.1 points."

Su Xiao almost extracted all the beneficial parts of this potion. Even so, the 0.1% reduction in willpower was like gangrene attached to the bone and could not be removed no matter what. This made him realize one thing.

.

The ingredients of this potion are like a gourd balloon. The larger end is the gain, and the smaller end is the debuff. Even if you deflate the gain end, it will make the small end smaller, but it will not make it smaller.

The smaller end disappeared, and therefore, the "Evil Dragon Potion" had a third version:

"Permanently increase health by 210,000 points and permanently reduce willpower attribute by 50 points."

As expected, the gain and debuff of this potion were connected. Su Xiao improved the gain characteristics at all costs, but a large number of expected debuff characteristics did not appear. The dozens of expected debuffs were all replaced by the word "reduction of willpower".

This debuff is swallowed up.

Yes, it is swallowing. This is not an adjective. It is the debuff characteristic of this potion, which corresponds to some kind of living creature that is particularly difficult to detect. Su Xiao tried to use a microscope to observe it to the greatest extent, but still did not notice anything.

, so he uses contract testing instead.

Take the side effects of this potion as the price of a contract, and then use the "Contract Code" to determine the characteristics of this price. The final result is:

Creeping, erosion, parasitism, discipline.

Based on the three characteristics of creeping + erosion + parasitism, we can basically judge that this is a living creature. Let’s call it a hidden leech. The reason is that this kind of living creature will absorb the host’s willpower like a leech sucking blood.

The key is the last "commandment" feature, which means that as long as you don't drink this potion, the hidden leeches in this potion will definitely not take the initiative to invade. I can only say that you are lucky this time. There is no risk in preparing this potion, as long as you don't drink it.

, and therefore, the fifth version of this potion was created.

"Permanently increase the health value by 620,000 points, permanently reduce the willpower attribute by 150 points, and have a high probability of causing the willpower attribute to continue to decline for a period of time."

After Su Xiao discovered that hidden leeches had the property of devouring negative effects, he simply stopped using potion materials with life characteristics to enhance the "evil dragon potion". It was too expensive. He used various types of medicines that were a hundred times cheaper than materials with life characteristics, but had strong side effects.

Materials to enhance "Evil Dragon Potion".

Su Xiao looked at the attractive rose-red potion in her hand. In some cases, using this thing to deal with the enemy is more effective than poison, especially when playing against a big force and trying to get rid of a high-level person of this big force.

member time.

After thinking for a moment, Su Xiao started mixing again, this time adding extremely powerful drugs, and finally got the fifth version of "Evil Dragon Potion".

"Permanently increase the upper limit of life span by 10%, permanently increase health points by 300,000 points, permanently reduce the current willpower attribute by 30% + 150 points, and have a high probability of causing the willpower attribute to continue to decline for a period of time."

Of course, this thing cannot be sold as a buff potion. After taking this into consideration, I contacted Caesar and asked him to help 'buff' it, which means to make "permanently increase the life limit by 10% and permanently increase the health value by 300,000 points" more obvious.

The part that deducts willpower becomes almost imperceptible and can only be seen by notarizing it through the Void Tree or the Paradise camp and checking the attributes.

I originally planned to get rid of the evil heart in the near future, but now it seems that I might as well postpone it. Take this bottle of "Evil Dragon Potion" as an example. If a high-level member of a hostile force drinks this thing, the destructive power it will cause will be greater than the direct poison.

A dead opponent is a hundred times stronger.

As for relying on high willpower to resist the debuff of this thing, there is no such possibility. This is to eat through the willpower. In the future, the hidden leech will continue to suck the host's willpower, causing the host to have negative willpower.

By then, the host's behavior will be unpredictable, sometimes angry, sometimes crazy, sometimes with spreading desires, sometimes cruel and bloodthirsty.

Baha flew in from the window and brought back a wooden box. After opening it, there was a precision core the size of a marble. Su Xiao took out the "Mysterious Eye", and the "Mysterious Eye" began to resonate with the core and flew away on its own.

It unfolds, absorbs the core into it with a click, and then closes it.

Buzz~

The "Mysterious Eye" made a violent buzzing sound, with dense rune structures lighting up on it, and then subsided after a moment.

The "Mysterious Eye" fell into Su Xiao's hands, and it seemed that there was no change. After studying for a while, he felt the improvement of the "Mysterious Eye", first of all, the detection, unlocking and other functions were greatly improved. Even he developed

"Swirling Flashbang Mode", the effect is enhanced more than a hundred times.

It used to emit a strong light that could make people feel severe pain, but now it directly shocks the body and soul. Even with Su Xiao's current body and soul strength, it would take a long time to be hit. The only problem is that this function is useless.

.

The flash bomb is useful, but it can be useless if you add the spin feature. What's even more deceiving is that this spin has a strong tracking effect. As long as Su Xiao throws it, no matter how fast he evades it, the spin flash bomb mode

The mysterious eyes under him will track accurately to ensure that it will explode in front of his eyes.

As for the other functions of the "Mysterious Eye", he still has to develop it himself. Perhaps those masters of alchemical mechanics did not even consider it when making this thing. After this thing fell into the hands of an alchemical potion master,

, what kind of scene it will be.

Su Xiao came to the basement of this building, where Amu had dug a shaft and built an elevator. He took the elevator down and went several hundred meters underground before the elevator stopped.

This is an underground space of more than ten square meters. The whole is semicircular, like a large upside-down bowl. The walls are made of a kind of gray-white chitin. This special chitin has a strong load-bearing capacity.

Densely packed sealing techniques were engraved on the surrounding walls. After checking that there was no problem with these engravings, Su Xiao took the elevator back the same way. As soon as he returned to the bedroom on the third floor, Baha said:

"Boss, the demon has arrived at the Eternal Clock."

"..."

Su Xiao sat on a wooden chair and looked at the projected picture. The demon spirit incarnate stood on a pale land. A black and blue bell thousands of meters high was hung in the sky by a thick chain. The clouds and mist were eternity.

There is flow above the big clock, and when you look at the big clock from below, there is chaos inside the big clock.

A few hours ago, the incarnation of the demon spirit arrived at Smile Town on Skeleton Island. As a result, the demon spirit failed to penetrate here. The weird people here were very powerful. As a price, more than 80% of them were killed by the demon spirit.

In the end, the demon spirit incarnated in an old house in Smile Town and found a secret passage deep underground. After arriving 10,000 meters underground in Smile Town, there was a passage made of bones. Follow the passage of bones for more than ten kilometers.

After taking the elevator at the end, the demon finally arrived at the secret island corresponding to the hidden mission.

There is a dilapidated ruins on this secret island. In the center of the ruins is a tall stone tablet, which records the method of activating the "Eternal Clock". To be more precise, the "Eternal Clock" is actually a test.

There are three stone tablets recording the secret of the "Eternal Clock". One is on the "Island of Bones" and should have been found and destroyed by the priest. The other is on the secret island, and the last one is on the second floor of the dungeon in "Yuhui Town".

Keeped by the spirits of darkness.

The reason why I know this is that there is a dead body near the stone monument on the secret island. Inside the bear skin package of the dead body, there is a notebook that records the experience of the dead body. This is a pilgrim who escaped midway, and the guilt of running away.

, allowing him to travel around the world and write down this precious notebook, and when he was about to take it back to Ash City to atone for his sins, he died on the secret island at the last stop.

The demon spirit incarnated and went to the secret island. Of course, he also used the "cursed index finger" to open the "hidden mechanism" on the secret island. Through the prompts that appeared, Su Xiao knew what was sealed in the underground palace of this mechanism. It was from this world.

Big boss: The huge cursed devourer.

There used to be two major forces in this world, the Ancient Soul Temple and the Glory Temple. Now this huge curse devourer is the last leader of the Ancient Soul Temple. There are even rumors that this person is responsible for the intensification of the curse.
