Tianwu Mountain!

Over thousands of feet, the mountains are shaded by vegetation, streams and waterfalls, the scenery is beautiful, the air is fresh, and the birds chirping, Lu Chen feels relaxed and happy in it.

A stone road leads straight from the foot of the mountain to the middle of the mountain. Lu Chen walks along, enjoying the beautiful scenery, and he feels particularly relaxed, without disputes and worries.

This is really a paradise!

Lu Chen walked for an hour and came to the end of the mountain road. His eyes suddenly became clear, but he saw that there was a large valley inside.

In the middle of the valley is a small lake, the lake is clear, you can see the fish swimming happily, a bamboo bridge from the outside to the inside, leading directly to a bamboo house.

The bamboo house is located in the middle of the lake, like a small building in the middle of the lake. The lake is full of lotus flowers, and there are egrets flying, which is better than a fairyland on earth.

The small building is very lively, with no fewer than hundreds of people. There are residents here as well as contestants from various spaces on the second floor of the ancient tower.

They all come for Huo Niguo, such as Fengqing.

Lu Chen is no exception.

What only made him strange was that some contestants were watching, some contestants were actually refining pill, including Fengqing.

How is this going?

Lu Chen was puzzled.

"Lu Chen, I didn't expect you to come."

At this moment, a tall, blond, lion-nosed young man walked up and looked at Lu Chen with a smile.

Who is he if he is not Chu Baitian?

"Brother Chu, what pill are they refining?" Lu Chen asked.

"They were instructed by the two seniors, Wuyang and Wuyin, to refine a pill called Yin Yang Heqi Pill." Chu Beitian said.

"Yin-Yang Heqi Pill? What kind of pill is this?" Lu Chen asked in surprise.

He is also an elixir master anyway, plus he has been in the elixir hall, knowing a lot of elixir, but he has never heard of this pill.

"I am not an alchemist, and I don't know this pill, but I heard them say that this pill uses yin and yang as medicine." Chu Beitian said.

"How is it possible?" Lu Chen asked in amazement.

The two qi of yin and yang are the qi of heaven and earth.

"Yeah, I don't think it's possible, too, but unfortunately, this is the requirement of the two seniors of Wu Yang. Only by refining this pill can you obtain the Huo Nirvana." Chu Baitian said indifferently.

Lu Chen nodded thoughtfully and looked at the contestant. They were refining the pill, but at this moment, there was a sudden explosion.

"Boom!"

A contestant flew upside down, vomiting blood and fell to the ground and cried out in pain.

"Fryer again."

Chu Baitian shook his head slightly, as if he had become accustomed to this.

"How long has Brother Chu been here?" Lu Chen asked in surprise.

"Me and Jiang Qiong are the first batch of contestants to come here. Unfortunately, none of us are alchemists, so we can't try to refine Yin Yang Aqi Pill." Chu Beitian said.

When Lu Chen heard this, he was slightly surprised and looked around, and he saw Jiang Qiong and Li Qian, but they both watched from the sidelines and didn't mean to act.

Lu Chen frowned slightly, and immediately looked at Feng Qing. Among the contestants who were refining the Yin-Yang Heqi Pill, besides her, there were Yong Yuan and Huai'an.

These two monks were also alchemists, which surprised Lu Chen.

"Brother Chu, I'll take a look, I'm out of company."

Lu Chen bowed his hand to Chu Baitian, and then walked up.

"It is rumored that Brother Lu is also an alchemist, do you also want to refine this Yin-Yang Heqi Pill?" Chu Baitian suddenly followed, and asked as he walked, looking at Lu Chen curiously.

"I am an alchemy master, but so many people have ended in failure, I am not very sure." Lu Chen said calmly.

"The two seniors, Ling Daozi and Huang Wuzi, unexpectedly came up with this topic in this space. If you want to come to it, it will be very meaningful. Brother Lu may wish to try. The two seniors of Wuyang can say, who can refine Yin and Yang. Pill, you can also get the Pill Dao Book and Pill Refining Book that they have compiled." Chu Baitian said with a smile.

"Pill refining treasures? Brother Chu, what is this?" Lu Chen asked strangely.

"It seems that Brother Lu doesn’t know the two seniors, Wuyang and Wuyin. They are one of the only four Ninth Grade Immortal Alchemy Masters in the Fairy Continent. In order to prevent their alchemy from being lost, the two seniors will learn all of them , Compiled into a book, which is what I just said about alchemy treasures." Chu Baitian smiled softly and said to Lu Chen.

Lu Chen's eyes lit up after hearing this, and his breathing became short.

This alchemy treasure is the life effort of two Ninth-Rank Immortal Alchemy Masters. If they can obtain it, wouldn't alchemy techniques advance by leaps and bounds?

You know, although he can now refine the fourth-rank elixir, and even the fifth-rank elixir, he doesn't know much about the elixir after all, especially the understanding of the high-level elixir is extremely scarce.

If there is a pill refining treasure, this problem will be solved even tough.

Lu Chen immediately made up his mind to refine this Yin-Yang Qi Pill, not only to obtain the alchemy treasure, but also to obtain the fire nirvana and complete the test of this level.

"It seems that Brother Lu has been tempted." Chu Baitian smiled and continued, ‘If Brother Lu wants to participate, he can ask the two seniors of Wuyang to grant both yin and yang. ’

"I don't know where the two seniors of Wu Yang are?" Lu Chen asked.

"Nuo, it's inside Xiaozhu." Chu Baitian pointed to Fengqing and the others on the other side of alchemy. There was a bamboo pavilion with an old man and an old woman sitting left and right to make tea.

Seeing these two elders, a flash of shock flashed in Lu Chen's eyes. Looking at the spiritual power of his Yuan Wonderland, he found that Wu Yang and Wu Yin had no power fluctuations.

Obviously, the cultivation base of these two elders was much higher than that of Lu Chen.

"The two seniors are both ancestors." Chu Baitian said as if he could see Lu Chen's mind.

"That's it, Brother Chu, thank you very much." Lu Chen took a deep breath, handed over to thank him, and then walked to Zhuting. He didn't walk for long, and there was another bang behind him.

Lu Chen shook his head secretly, using yin and yang to refine alchemy, unheard of, can he really succeed? But no matter what, I have to try it myself.

After a while, Lu Chen entered outside the bamboo pavilion and did not continue to walk forward. Instead, he bowed his hands and said, "Junior Lu Chen has seen two seniors. The junior wants to refine the Yin-Yang Aqi Pill, please give the two seniors to give the two qi. ."

"Are you Lu Chen?"

The old man Wu Yang was thin, but he had a childlike appearance, his skin was fiery red, and his eyes were bright and wise, like a wise man who read everything. He looked at Lu Chen with a hint of surprise.

The old woman Wuyin was slightly fat, with a round ground pavilion, kind eyebrows and kind eyes, and she looked rich, like a kind old woman who looked at Lu Chen with a smile.

"It's a junior."

Lu Chen didn't dare to neglect, and replied sternly.

The two elders Wuyang and Wuyin knew his name, which surprised him, but he did not ask.

The two elders are both ancestors and they must have known Ling Daozi, and Ling Daozi knows everything about the Lingbang Contest. Perhaps the two elders learned of themselves from their mouths.

"Lu Chen, this is yin and yang, you can take it."

Wu Yang glanced at Lu Chen, did not say much, waved his palm, and a white bottle flew out and fell in front of Lu Chen's eyes.

"Thank you two seniors."

Lu Chen took the white bottle, bowed his hand, and turned away.

"My wife, do you think this is feasible for Lu Chen? I heard Senior Lingdaozi say that his alchemy is different, maybe he is the person we are looking for."

Wu Yang glanced at Lu Chen, holding up the teapot, pouring Wu Yin a cup of tea, and inquiring.

"The old man, with our alchemy, neither yin and yang can be refined into a pill. Even if his alchemy is different, I am afraid it will be difficult to succeed." Wu said indifferently.

"Yeah, if the old guy Hong Santong predicted that we could find this person in this competition, I wouldn't agree to the two Lingdaozi." Wu Yang snorted.

"Hong Santong's technique of divination has never been wrong. He said that if there is one, there must be one, but I don't know if it is Lu Chen or someone else?" Wu Yin glanced at Lu Chen and said unhurriedly.

"No matter, let's wait slowly, I hope this person will appear earlier, otherwise, the barrier outside the domain will not last long." Wu Yang shook his head and said.

"The extraterritorial celestial demon invades my fairyland every hundred million years. I don't know why this time, but they will send soldiers to investigate in advance." Wu Yin said softly.

"Who knows. Fortunately, only some ancestors were dispatched. If it were the ancestor gods, I am afraid that the outer barrier will not last for a few years." Wu Yang sighed.

He seemed worried about the invasion of the extraterritorial demon.

However, many contestants did not know that the refining of Yin-Yang Heqi Pill was for the purpose of extraterritorial barriers, including Lu Chen.

At this time, he took the white bottle and went to the other side, where Feng Qing and the others were practicing alchemy.

"Boom!"

There was another explosion, but when one of the contestants retreated with a sigh, he was not bystander, but Li Qian.

As the Young Master of the Qinglian Sect, he also possessed a superb alchemy, and he was a fourth-grade elixir master, but unfortunately he failed.

Lu Chen looked around and found that among these people, Feng Qing, Yongyuan, and Huai'an were the most stable and concentrated on using the fire pill to refine the Yin-Yang Heqi Pill.

"Hey, isn't that Lu Chen? Why did he come? Isn't he also an elixir?"

At this moment, many contestants were surprised when they saw Lu Chen.

Lu Chen ignored them and took out the tiger stove.

"Tsk tsk, fourth-rank pill furnace, so Lu Chen is a fourth-rank immortal pill master?"

"He is so strong that he is still a Fourth-Rank Immortal Alchemist, it's really incredible."

"I don't know if he can do it?"

"Definitely not, didn't the previous Li Qian fail?"

"I hope he can succeed, so that we will have other tasks, otherwise I really don't know when we will be able to pass this level."

Participants who do not know alchemy have a lot of discussions. Most of them are not optimistic about Lu Chen, but some hope that Lu Chen can succeed. Of course, this type of people also hope that Feng Qing and others can succeed.

At this moment, they are all holding the mind that the blind cat can meet the dead mouse, so that they can avoid this level and take other tasks.

"Boom!"

At this moment, another bang came, it was Huai'an, and the pill furnace in front of him made a muffled sound, overflowing with black and white yin and yang.

Seeing this, Lu Chen secretly cried out, it was a pity that these were both Yin and Yang, and if he could give himself, he might be able to increase the strength of the Universe Soul Seal.

Looking at the white bottle in his hand, Lu Chen's eyes were also a little hot, yin and yang are rare, right now, it's a pity that he can't use it.

"No matter, let me first think about how to refine Yin Yang Aqi Pill."

Lu Chen sighed lightly, looking at the white bottle in his hand, frowning slightly, the Yin-Yang Heqi Pill, could it just consolidate the two Qis of Yin and Yang together?

If this is the case, why did Li Qian, Huai'an and others fail?

Lu Chen's original intention was to use the method of refining pills to fuse the yin and yang with a vessel, but he hesitated after seeing the failure scene of Li Qian and his colleagues.
