The system gives me immortality, and I will eventually become invincible while I’m alive.

Today, the wind is gentle and the sun is beautiful, the high-pitched eagle chirping can be heard in the sky outside Wuyun Sect, and five green cliff eagles pierce the sky.

After the trip to Nandoushan half a year ago, these disciples finally came back. The inner disciples were filled with hope, and the elders of the sect were filled with eagerness.

The green cliff eagles landed in front of the sect leader's hall. Only less than a hundred people survived this year, which can be said to be a heavy loss, but the harvest of elixirs was quite fruitful.

The sect master and the elders also encouraged them, and the remaining disciples also walked in silence. Many of them had blood stains on their bodies, and a cold light flashed in their eyes from time to time.

They followed the elders down the mountain without saying a word. This year's competition was too fierce. Some of the ten disciples of the Immortal Sect even sacrificed high-grade yellow-level magic weapons, and no one could stop them.

Under the sect leader's peak, a man led a black cow and looked at the mountain road from a distance, as if waiting for something.

One by one, the disciples began to fly with their swords after coming down the mountain, heading in various directions, but they still didn't seem to find that person.

The big black bull kept snorting heavily, and fewer and fewer disciples were coming down the mountain. Why were they still not seen?

Chen Xun clenched his fists tightly and stared in that direction. The corner of his eye kept lingering on those disciples, but he never saw that person, even if he looked similar.

"Moo Moo?" Da Hei Niu looked at Chen Xun with an extremely nervous expression. His disciples had already gone down the mountain sparsely, and there was almost no one left.

"Old Niu, I don't dare to give Senior Brother Ji the Foundation Building Pill first, otherwise it will be a huge disaster for him and us."

Chen Xun said with a hint of trembling, Brother Ji may really not be back...

"Moo~" The big black cow barked in a low voice, and no one in the distance came down the mountain anymore.

"Haha...Old Niu, let's go, we have really tried our best."

Chen Xun reluctantly smiled and said, holding the bull's head in one hand, "Do your best and obey fate. At least Senior Brother Ji has tried his best. He has no regrets, and neither do we..."

"Moo~" The big black cow rubbed against Chen Xun, feeling depressed.

The fallen leaves rustled, and they turned and left, their backs carrying endless loneliness.

The blazing sun swayed above the sect's main peak and slowly sank. A few white clouds on the horizon dispersed and turned into a colorful sunset.

At the foot of the mountain, the afterglow of the setting sun shone on a hurried figure. Because he won the first place, he was left alone by the sect leader to encourage him, so he came down a little late.

Suddenly this figure paused, as if he had seen something. His eyes suddenly opened, and he seemed to have used all his strength to shout in one direction:

"Master Chen! Junior Brother Niu!"

A familiar voice suddenly came from a distance. Chen Xun and Da Hei Niu were shaken as if they had received an electric shock. Their footsteps stopped at the same time, their eyes trembled slightly, and they were in a state of half-daze.

Chen Xun slowly turned his head and saw a figure standing at the foot of the mountain in the distance, and this person... was none other than Ji Kun!

Ji Kun's countless words seemed to be stuck in his throat. His eyes were red and he was full of energy. The blood marks on his body gave him a masculine air.

His old temperament seems to have returned. Although he has gray hair, he doesn't look old in any way.

Ji Kun didn't say a word in the end, but just nodded heavily to Chen Xun.

"Moo moo!!" The big black cow jumped excitedly and stood up suddenly. The momentum shook the fallen leaves on the ground and kept flying.

Chen Xun's eyes were deep, with a smile on his lips, and he nodded heavily to Ji Kun.

He took the big black cow and left, and the two of them never exchanged a word from beginning to end.

Ji Kun solemnly raised his hands towards their backs and slowly looked at his storage bag. The contribution value of this yellow-level high-grade magic weapon was at least 3,000, and it could only be redeemed by monks in the foundation-building stage.

He had gone to inquire about it a few months before his trip. Chen Xun had lied to him and was so kind that he would never thank him. This was enough for him to remember for the rest of his life.

Ji Kun stood with his hands behind his hands, looked up at the sky gently and sighed, with mixed feelings in his heart. The road to immortality is full of intrigues. It is really good to meet such a friend, so great...

……

After Chen Xun and Da Hei Niu returned to the elixir garden, they felt excited. They looked at each other deeply, smiled knowingly, and added this year's longevity points to their mana.

"Old Niu, I'm going to refine the foundation-building pill for Senior Brother Ji, but it's not like ours, otherwise the foundation-building pill will definitely fail."

Chen Xun said seriously, frowning slightly, "There may be something wrong with the Foundation Establishment Pill sent by the sect. When the time comes, I will take the initiative to ask Ying to send the pill and then replace it."

"Mo moo?" the big black cow asked nervously. It didn't know how to make alchemy.

"It may be a defective product... but it is definitely not a top-grade foundation-building pill."

Chen Xun said in a deep voice, looking at the big black cow, "But this is just my personal guess. Whether it is defective or not, I have to replace it. Brother Ji only has this last chance."

He didn't just hang around in the Alchemy Hall. He learned a lot after all. For example, there are different levels of elixirs: low-grade, medium-grade, high-grade, and top-grade.

As for the news about the pill pattern, he has not heard about it and has no access to it. He is also slowly groping about the pill test. Nowadays, the pills used in the Qi refining period can be roughly seen. The foundation-building pill cannot be seen yet. out.

"Moo!" The big black cow nodded heavily, doing everything cautiously, and nothing would go wrong.

"We have figured out the exploration rules of this formation. We only need to miss those two time points every day, and no one will know what we are doing."

Chen Xun squinted his eyes slightly and looked at the stream of light that flashed across the sky from time to time. If it hadn't been for the warning and cover of the essence of all things, they would have been exposed long ago, and they would have been unaware of it.

"Moo~" The big black cow also looked up at the sky solemnly. There was something dirty here, and it was by no means as casual and beautiful as imagined.

"Old Niu, let's get started." Chen Xun smiled slightly. With the essence of all things nowadays, they can already cultivate a 120-year-old elixir in one month.

"Moo!" The big black cow quickly ran towards the cave they opened at the bottom of the hill. There was a large amount of foundation-building elixir in the storage bag in its belly.

They once made a bold attempt to uproot an elixir in the medicine garden from the spiritual field, but the formation did not respond. It is quite normal to change the place where it grows. As long as it is not taken out or damaged, everything is fine. .

But if the elixir grows in the wrong year, then it is the responsibility of those who pick the elixir in the alchemy hall. The formation does not have such detection effect yet.

They also randomly planted a few common elixirs, but none of them responded, as if they were reacting to the recorded elixirs. They have too many secrets and must be careful.

Inside the cave.

Chen Xun started to refine the elixir, and the control of the elixir fire was quite ordinary. This time, he did not integrate all the elixirs together, but divided the liquid among them.

Dahei Niu continued to cultivate elixirs on the side. When he had nothing to do, he read books to remind Chen Xun when to evade. Time just passed by as Chen Xun refined the elixir.

He kept trying every day. Depending on the potency of the medicinal solution, the quality of the pills was also very different, but no pills with pill patterns like theirs appeared again.

Now that he has his spiritual consciousness, the rate of elixir formation has greatly increased, and he can accurately control the elixirs in the alchemy furnace. However, in fact, his alchemy techniques, coupled with the bonus of elixir fire, have reached a quite terrifying level.
