The entire city of Raven was shrouded in a strange red light, and a huge magic array emerged.

Xiao Yan had long known that Yuri was stalling for time, but he was not sure whether Yuri was waiting for reinforcements or an event. Although Yuri didn't confess the truth, when he saw that he handed over the purple prop "Red Stone", Xiao Yan was so frightened that he almost lost his temper.

After summoning the flying dragon, Xiao Yan didn't care that the air defense fire might mistake him for a zombie and knock him down, so he immediately pulled Luo Ze and rushed to the sky, and the terrifying alchemy circle then flooded Raven City like a tide.

Viewed from above, the circle resembles a snake biting its own tail, a sharp sword passing through from top to bottom, and the snake's tail is tightly wrapped around the blade.

Ouroboros! This famous biting snake mark represents "self-reference" or "infinite loop" and is mentioned in many alchemical texts and stories.

"This! What is it? Luo Ze hugged Xiao Yan's waist tightly, looking at the strange and evil scene on the ground in surprise.

"The circle of alchemy." Xiao Yan frowned, "Even if I don't know alchemy, I can roughly guess the overall situation that Yuri and the organization behind him have laid out in this world now." ”

In the current world that is not powerful but extremely chaotic, with the unprecedented panic and opportunity brought by the zombie siege, Yuri's location organized a giant refining array.

A refining array that sacrifices the lives of the whole city.

What did Yuri gain with the help of the props and knowledge they gained from other dimensional worlds at the expense of the citizens of the city?

This answer is so famous that Xiao Yan and Luo Ze have heard of it in the original world!

Philosopher's Stone! It is also known as the Philosopher's Stone in some dimensional worlds.

It is an alchemical product with amazing functions.

Many people have misconceptions about alchemy, thinking that alchemy is just the magic of refining gold, of course, it is undeniable that this is indeed the original intention of alchemy, but after thousands of years of development, alchemy has become a scientific system, and alchemy has developed into a philosophy in ancient Greece, believing that everything in the world is composed of four elements: air, water, earth, and fire.

The Philosopher's Stone can turn any metal into pure gold, and it can also create an elixir of immortality. Over the centuries, there have been many reports about the Philosopher's Stone, the most famous of which belongs to the famous alchemist and opera lover Nicolas Flamel. He had at least six hundred and sixty-five birthdays and now lived in seclusion in Devon with his wife, Perenar (six hundred and fifty-eight). On his plane, the Philosopher's Stone was originally called "Philosopher's Stone" and was written "Sorcerer's Stone" for ease of understanding.

The Philosopher's Stone does not have to be a stone, but may be in the form of a red liquid or powder. Regardless of the form, it has the following functions:"

1. Turn stones into gold!

2. Give the holder unlimited vitality!

3. Powerful increase in magic or alchemy effects! ”

The alchemist Nicol Lemay, who obtained the Philosopher's Stone, was immortalized as a result.

Redstone functions similarly and can be seen as a product of deterioration.

"Whatever you get, you have to pay for it. This is the principle of equivalent exchange at the heart of alchemy! Even in such a chaotic zombie world, it is impossible to carve the magic circles all over the city without causing the government and the military to intervene. Yuri: They are also not strong enough to stand up to the state apparatus. Xiao Yan said slowly with a pale face.

Therefore, they went underground and used a large number of drillers to carve an alchemy circle in the underground of Raven City. It avoided the detection of the army to the greatest extent. However, near the city hall line, the army is extremely closely monitored, and their circle will probably not be able to bypass this location. ”

"So they repeatedly drove the corpse tide to attack through the catalyst?" Luo Ze listened to Xiao Yan's explanation, and gradually understood, "They actually have such a strong strength. Isn't this already playing with the existence of this plane in applause? Entire cities, and even the whole world, can be turned into raw materials at their disposal, given given enough time. ”

"I also find it strange. The original intention of the dimensional space should be to take the postgraduate examination, hone us, and then decide the strong, just like raising Gu. Xiao Yan nodded, "But Yuri, they have already refined their energy directly from this world. Wouldn't it cause a backlash from the will of the plane? ”

The reaction of the refining array did not last long. Soon, all life on the ground was gone.

A sparkling red gem hovers above where Yuri's body was lying.

Xiao Yan drove the flying dragon to land cautiously and held the bewitching red stone in his hand.

"You have obtained the Most High Creation: the Philosopher's Stone. Grade: ??。 Special effect:

1. Turn stones into gold!

2. Give the holder unlimited vitality!

3. Powerful increase in magic or alchemy effects!

Notes: If you are weak, you will not be able to use this Arcana, and will be punished for holding or using the Will of the Summoned Plane.

Notes: Due to the power of the Philosopher's Stone, it is far beyond your control. The only way to forcibly use the Philosopher's Stone is death and destruction. Boost your stats and rank before attempting, or give the Philosopher's Stone to powerful characters.

You and your teammates are bathed in the brilliant light of the newborn Philosopher's Stone, and because you are too weak, you have been blessed with the power of the Philosopher's Stone.

You gain +5 Amplification for all stats.

Your current stats are: Strength 31, Agility 21, Stamina 36, Perception 12, Intelligence 12, Spirit 9, Charisma 8.

Your agility stat has exceeded 20 points, please choose your stat peak reward carefully:

1. Agility: Increases your attack and movement speed by 5%;

2. Sensitivity: Increase your dodge chance by 10%;

3. Swiftness: Increases your movement speed by 15%. ”

Needless to say, Xiao Yan chose to be sensitive, and the effect of being able to completely dodge the enemy's attack is not too small.

"Griffith, Griffith, did you see that!" Luo Ze was as excited as a little girl who received a Christmas gift, "+5 for all attributes, oh my God, it's over!" ”

Xiao Yan was also excited. Judging from the performance of the other contractors, he has only experienced two worlds, but his attributes are already frighteningly high, and he is likely to surpass most of the veterans.

Stroking the sage stone in his hand, Xiao Yan's mind turned: "This harvest is also earned by myself, and I don't know if the space thinks that he has paid enough price." ”

In addition, killing Yuri just now also yielded 5 pieces of catalyst. This eerie-smelling potion can attract a large number of zombies in the vicinity, but it does not do much else.

This Yuri is also quite single, and he doesn't have much equipment other than that. Xiao Yan only gained no more than 500 general points and a little potential point. It seems that Yuri is also smashing the pot and selling iron for this mission.
