In front of the Spirit Grass Garden.

"I heard that the Second Elder has been refining the Returning Void Pill recently. Su Dong said with a smile.

The pill is divided into six grades.

Xianfu Dan, Taixu Dan, Guixu Dan, Transformation Dan, Dacheng Dan and Xiandan. For example, the Taixu Pill can only be taken by the Taixu monks, and the Xianfu monks at the lower level of the realm can only take the Xianfu Pill.

This Returning Void Pill is the highest level of the Immortal Mansion Pill, and ordinary Immortal Mansion monks have to go through many tribulations if they want to become Taixu Monks, and finally have to go through the Taixu Tribulation, and this Returning Void Pill can weaken the power of the Taixu Tribulation, making it easier for Xianfu monks to enter the Taixu realm.

"So what?" the second elder frowned.

He has been stuck in the Immortal Mansion Monk for hundreds of years, and this return to the Void Pill is his last hope.

"I have a unicorn fire...... I heard that if you can have a good flame in refining the Returning Void Pill, the success rate will be greater. Su Dong smiled and said.

"Really?" the second elder's eyes widened.

The Qilin Fire is the spiritual fire of heaven and earth, and it is also the natal flame of the ancient Qilin, if it can help him refine the Returning Void Pill, then ......

"Look at it. As soon as Su Dong's divine sense moved, a small wisp of unicorn fire appeared in the air.

"This ...... This...... It's really unicorn fire. The second elder's face showed ecstasy, he was an alchemist, he was familiar with flames, and of course he recognized this Qilin fire.

Su Dong immediately called the machine spirit to put the qilin fire back, and then looked at the second elder with a smile.

"Since I won't lie to the second elder, how about we make a deal?" Su Dong said.

"You say. The second elder stared at Su Dong. He didn't want to see Su Dong before, but now how to look at it, Qilin Fire, there is hope for returning to the Void Pill!!

"Now I can't master this Qilin Fire, I need those three kinds of immortal grass, you give me the immortal grass, and I will help you refine the Returning Void Pill, how about it?" Su Dong smiled slightly.

"This ......," the second elder frowned.

Ice Immortal Liquid, Han Tiancao, and Moonlight Fruit are too precious and rare, and he only got them after walking outside for ten thoughts, and they are only seeds.

"Second Elder, if you can break through the Taixu Cultivator, what use will these three kinds of immortal grass be for you?" Su Dong continued to persuade.

The Taixu Cultivator didn't need these three kinds of immortal grass.

"This ...... This...... All right. The second elder nodded.

He also figured it out, using these three kinds of immortal grass for a big realm? Even if it only increases the breakthrough rate, it will be earned, you must know that the further the immortal cultivator goes, the more difficult it will be to break through, if he lets go of this opportunity, it will be difficult to break through in the future.

"Come with me. The second elder walked into the Spirit Grass Garden.

Su Dong pulled Xiao Qianlian to follow.

"You kid has to master the Qilin Fire as soon as possible, if you can't help the old man at that time, the old man will have to go to your father's. The second elder snorted.

"It's nature. Su Donglian nodded.

The Lingcao Garden is a pastoral, and the countryside is divided into various courtyards, and each courtyard is planted with a kind of fairy grass.

Su Dong and the three of them walked to the deepest part of the Spirit Grass Garden, which was a separate courtyard with several squares, and the courtyard was full of spiritual energy, and Su Dong could see at a glance that there was a formation that gathered spiritual energy around this Spirit Grass Garden.

"Second Elder, you don't seem to be proficient in the art of formation. Su Dong asked in confusion.

"I let the fifth child arrange it. The second elder said casually. The fifth elder is the fifth elder of the Ethereal Gate, who is proficient in the art of formation.

"I see. Su Dong nodded.

Each elder has a craft, such as the second elder refining the elixir, the fourth elder refining the magic weapon, the fifth elder proficient in the formation, etc., without the craft, he can't be an ethereal elder.

The second elder stopped in front of a courtyard, and Su Dong and the others also stopped.

"The fairy grass planted in this courtyard is the most precious, you kid lion opened his mouth, and all he wants is the fairy grass in this courtyard. The second elder rolled his eyes and said. He felt distressed when he thought about it.

Su Donglian walked into the courtyard.

"Which three?" There are really a lot of fairy grasses in this courtyard, and Su Dong can't tell which one is which.

"The ice fairy liquid is that milky white, similar to Xiang Yuekui. ”

"Han Tiancao is in the right corner, all white, exuding a hint of coolness. ”

"The moonlight fruit is on the far left, and the white fruit has a misty moonlight coming out. The second elder immediately pointed out.

Su Dong looked at it continuously.

There are three strains of Ice Immortal Liquid, three strains of Rare Heavenly Grass, four Moonlight Fruits, and there are only a few of them in the entire Spirit Grass Garden.

"I spent twenty years cultivating these fairy grasses, you kid ......," the second elder sighed and shook his head. It's a pity that there is no way, the Qilin Fire is too tempting for him, or the Void Realm is too tempting for him.

The second elder waved one hand, and immediately the three immortal grasses each flew out one and floated in the air, the second elder was an immortal monk, and it was not surprising that he had such magical powers.

"Just these three, you can take them. The second elder looked in pain.

"Thank you, Second Elder. Su Dong thanked him repeatedly, and then put away the three fairy grasses, and when the time wheel was there, he was not afraid that the fairy grass would lose its immortal energy.

"That kid has taken his leave, and when he subdues the Qilin Fire, he will definitely come to help the second elder. Su Dong hugged his fists.

"You kid just remember your promise, go, this Spirit Grass Garden not only has a defensive formation, but also an offensive formation, I'll take you out." The second elder waved his hand, he was not afraid of Su Dong's tricks, he was also a misty man, and Su Dong's father was the master of the misty sect, how could he cheat?

Su Dong and Xiao Qian immediately walked out of the courtyard door, the two elders led the way, no one saw it, a snow-white ball swished out of Su Dong's arms, whirring, the little claws waved out three times in a row, and the other few ice fairy liquids, Han Tiancao, and Moonlight Fruit were all gone.

Halfway up the Ethereal Mountain.

"Senior brother, you're done with your business, can I go back?" Xiao Qian said helplessly, he still remembered the sword trick.

Sue shook her head.

At this time, you naturally can't let Xiao sneak back, otherwise you will have an accident!!

"We went down the mountain, and there was a tea shop at the foot of the mountain, and the tea was very fragrant, so try it. Su Dong's eyes lit up.

Drink tea?

Chatting while drinking, the time passed quickly.

"This ......" Xiao Qian was almost depressed to death, and he couldn't understand what kind of nerves this senior brother was having today.

"Let's go. Su Dong immediately pulled Xiao Qian and ran to the foot of the Ethereal Mountain.

"Senior brother, the door master said that there have been a lot of things in the past two days, and I can't go out. Xiao Qian shouted. There is a magic enchantment in the Ethereal Mountain for a while, and outsiders can't enter it if they want to, but there is no enchantment to protect it when they get out of the Ethereal Mountain, and there is no way to encounter danger.

"How can there be such a coincidence, drink tea and go. Su Dong laughed.

The two of them galloped down the ethereal mountain.

Water Moon Day, Ancient Castle.

"En?" Shui Yue raised her eyebrows, and under her perception, the Qilin Fire that originally belonged to Chaoyuan was moving towards the foot of the Ethereal Mountain, and her beautiful eyes lit up, and she immediately took out the messenger stone, and the spiritual power was entered.

"The target is approaching you, set up, set up quickly. ”

At the foot of the Ethereal Mountains.

Tea shop around.

The ten cultivators dressed as mortals immediately dispersed, disguised as small servants, guests, and bosses, but the position where they were standing was obviously a formation circle
