The barracks in the main city began to upgrade, and everything was ready, leaving only time to fight against the wave of monsters behind.

And at this time, far away from the main city, West Lake Villa is a different scene.

The West Lake Villa, which is located on a large lake with blue waves, is a huge island, and the entire island has been covered by a colorful light shield at this time.

Originally, no one had the heart to appreciate such a beautiful picture, but everyone was in danger, and the nearly eight million people in West Lake Villa were all terrified, and they all took up arms and were ready to fight at any time.

Countless people in black and white clothes wandered around the island, holding pens in their hands, either writing characters on the entire island, or depicting mysterious patterns, and similarly, there were endless people wandering in the void of the island, and the chess pieces were embedded in the void, crisscrossing and crocheting a formation of formations.

Qin, chess, calligraphy and painting, these four professions, are the main professions of West Lake Villa, they are like idle clouds and wild cranes, indulged in qin, chess, calligraphy and painting, and brought these four professions to the extreme.

West Lake Villa, just like the places where the union took place in Sword Casting City, has formed its own characteristics with its development, and struggles in this world in its own way.

At the top of the island, there is a flat area equivalent to dozens of football fields, and the ground is a white slate, which has been outlined in an endless formation, 400,000 people, of which 100,000 are qin, chess, calligraphy and painting, and they are intertwined and reflected each other, and each one has a strict expression.

The whole West Lake Villa. There will be a catastrophe, and it will also be an opportunity, if they can avoid it, then they will soar into the sky and become a great force that will be decisive in the whole world, once they can't cope with it. Maybe it will sink forever, in short, there are opportunities and dangers.

And what caused this qiē was the 99-meter-high quaint Dading in the center of this open field!

Dading is simple, showing the color of bronze, and there are endless patterns of mountains, rivers, flowers, birds, insects and fish, but the most are the patterns of their respective plants, which almost contain the entire Dading.

And at this time. The whole tripod is flashing with clear light, and the patterns engraved on the tripod seem to come to life, and it seems to be extremely mysterious to get out of the tripod.

At the center of the formation was a black hole with a diameter of ten meters, and in the black hole, a white flame was spurting out. Burning the bottom of the Great Ding.

"Brother, when will it be completed? We're all set." Xi Wu asked anxiously.

Xifeng, the owner of West Lake Villa, did not answer when he heard his sister's words at this time, but looked at Da Ding with a stern face, his steps showed a mysterious step around Da Ding, and he kept making some strange gestures in his hand, and after each gesture was completed, a ray of light would appear in his hand to shoot on Da Ding.

When it comes down again in a circle. Only then did Xifeng stop, touched the sweat on his head, swallowed an elixir that he didn't know what it was, sat on the ground and gasped: "It's almost there, there is still an hour left at most to finish." If the alchemy is successful this time, the Yin Yang Fruit that will be produced by spending three hundred billion points to exchange for huàn will be able to refine at least ten Yin Yang Pills, and ten people will be able to open up the sea of qi at that time!"

Xi Feng, the owner of West Lake Villa, he is not only a strong man, but also an extremely talented alchemist, there are not many people until this point, after returning from the Devil's Domain with Tang Tian and them, he was ruthless, and used his savings to exchange a Yin Yang Fruit from the arena, and even spent ten times the value of the Yin Yang Fruit to exchange a Yin Yang Pill pill, preparing to make his own alchemy, refining the Yin Yang Pill that can open up the sea of qi!

"Is there still an hour left to make it? When the Yin Yang Pill is successfully refined, can we open up the Qi Sea to learn skills above the rank? I'm ready for the skill book of the humane pianist skills," Xi Wu said with joy.

"If nothing else, if you can refine the elixir of the Yin Yang Pill along the way, my sister will be able to open up the sea of qi after swallowing it, and learn the skill of laughing at the rivers and lakes", Xifeng looked at his sister and said with some doting.

"It's a pity, the sonic skill of Xiaoao Jianghu requires a pianist and a flute player to play together to exert the greatest power, a skill is clearly learned by two people, I don't know if Uncle Tang Tian can play the flute? I really want to play with him", Xi Wu said with some yearning.

Hearing his sister's words, Xifeng suddenly sweated profusely, and he didn't know what kind of demon his sister was in, why did he always miss Tang Tian?

Hum ......, at this time, above the big ding in the center of the square, the void shook, and suddenly a cyan vortex appeared, and an unknown thing between heaven and earth was converging towards the inside of the big ding, ignoring the surrounding formations.

"What's going on"? Xi Wu was startled and hurriedly asked, if something happened to the Yin Yang Dan, it would be over, wouldn't his dream of playing with Tang Tian be shattered?

"Sister, don't panic, this is a natural phenomenon, the Yin-Yang Pill is a three-grade pill, there will be some visions when the Dan is completed, this is normal, I am not worried when I see such a situation, because this means that this Yin-Yang Pill will definitely be successfully refined, but I don't know how many I will get", Xifeng said excitedly while comforting Xiwu.

The wisdom of human beings is endless, when some people are still thinking about using the Yin Yang Fruit to open up the Qi Sea, there are already people who want to use this thing to exert their maximum ability to refine it into an elixir, and the effect of a Yin Yang Fruit is several times or even ten times that of directly swallowing, there is no doubt that Xifeng is a person with this kind of wisdom.

Buzzing ......, at this time, the West Lake that surrounded the entire island was boiling, endless waves rolling, jetting waves tens of meters and hundreds of meters high, endless underwater mutant beasts churning and roaring in the water, but they just didn't rush to the island, as if they were demonstrating.

"Oops, what I was worried about really happened, but fortunately, I was prepared in advance", Xifeng said in a deep voice.

There is no leaky wall in the world, and the news that West Lake Villa has poured all its financial resources to refine the Yin Yang Pill was leaked out, and the originally calm West Lake suddenly boiled, and the monsters that were originally hidden under the water wanted to come and pick up the bargain.

"Master Xizhuang, we have been neighbors for so long, and we have been peaceful, and I also believe that you are a person without ambition, but now that there are good things, do you want to share them with me, a neighbor"? In the boiling West Lake, the water surface swelled like a fountain, and a pitch-black figure covered in scales appeared above.

A seventy-sixth-level carp demon, it got the news that West Lake Villa was refining the Yin Yang Pill, and instinctively felt that this thing was useful to him, and wanted to come and eat it.

"Hahaha, since there are good things, then there will definitely be no shortage of me, Master Xizhuang, Ming people don't say dark words, I know that what you refine is the Yin Yang Pill, I don't want more, just one, just give me a taste", once again a powerful mutant creature appeared on the other side, but it was a mutated water snake of level seventy-seven, churning in the lake, like a dragon.

Boom ......boom, boom, boom, as time passed minute by minute, the entire West Lake Villa was surrounded by boundless waves, and countless powerful and domineering stores appeared one after another, but they did not attack the West Lake Villa, but waited and watched.

More than seventy level demons have come to more than twenty, including crabs, loaches, fish, snakes, etc., all of them are creatures in the water, and even some strong people from the places around the Hope Mountain Villa have come, and their respective bird mutant beast powerhouses and animal mutant beast powerhouses have come, and the purpose is to refine the Yin Yang Pill successfully in the near future.

After these mutant beasts evolved extremely high intelligence, they also planted eyeliner among humans, but whenever there was any news, they would also be known, and now they knew how they could let go of good things, and they came one after another.

Seeing these guys appear, the solemn atmosphere of the entire West Lake Villa deepened a little again, Xifeng expected such a thing when he started alchemy, so he began to arrange it in advance, but he never thought that the attraction of the Yin Yang Pill would be so great, attracting all the strong and powerful people within thousands of miles around.

Although the West Lake Villa also got the news of the main city to clear the monsters, they did not make the same move, they were all working on the matter of refining the Yin Yang Pill during this time, and they were surrounded by a huge lake, and they couldn't clear the monsters in the water at all.

"Don't panic, everyone, now that my West Lake Villa has laid out countless formations, I only need to resist these monsters for an hour, and after an hour of Yin and Yang Dan will be formed and the sea of qi will be opened, these monsters will not have anything to worry about", Xifeng's voice rolled out and said.

In fact, once the Yin Yang Pill is successfully refined, after he swallows it, he learns the skills above the rank, and it is simple to kill these big demon level deposits, and there is no need to be afraid at all.

"I have to say that Xifeng Zhuang has a good abacus, tsk, take the Yin Yang Pill first and then kill us? To tell you the truth, we have already discussed it, at the moment of Dancheng, hundreds of our Dark and above Existence Zài joined forces to smash all your formations in one fell swoop, as for who gets the mature Yin Yang Pill in the end, it depends on their respective abilities", a gloomy voice said loudly, obviously not afraid of Xifeng's plans at all.

"Aren't you afraid that I'll give up halfway? so that all of you will not get anything"? Xifeng gritted his teeth a little and said, if it is really like what the other party said, I don't know if I really want to draw water with a bamboo basket.

"Are you willing"? Just a simple four-word rhetorical question, so that Xifeng had no words to refute......

(Thank you for the long comment given by that friend, the stone has been seen, thank you for your valuable advice, the stone will be seriously considered) (to be continued......)
