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

The next day, before dawn, Chen Xun and the big black cow walked on the road, heading west, and gradually disappeared deep into the street.

After the people around him woke up and took to the streets, they all heard that Chen Xun had left the hospital. Some people were inexplicably happy, feeling as if they had driven away the evildoer.

Some people felt disappointed and felt that Chen Xun was indeed a good doctor and he had not done anything evil.

But after a few days, everyone forgot about it. Whether Chen Xun left, he would not have more copper coins in his family. No one in this world would have the energy to care about a stranger.

……

The Ningyun Mountain Range stands tall and straight between heaven and earth, setting an example for the ages and inspiring all things. I don’t know how many years it has stood here.

The black and boundless cliff top stands tall against the sky like a knife and an axe, and the winding mountains are winding and circling, like a sleeping giant dragon.

Looking down from below, white clouds fill the air, and looking around the peaks, there are clouds and mist.

On the mountain path, a young man was looking for medicinal materials with a bamboo basket on his back, followed by a big black cow.

In the past three years, Chen Xun still added longevity points to speed. He wanted to see if he could no longer improve after reaching 20 points.

Their current point of immortality: strength, 21. Speed, 18.

It was also an extraordinary speed. If Chen Xun ran hard, he would not be able to see clearly with the naked eye, which is quite exaggerated.

"Old Niu, let's look carefully."

Chen Xun's bamboo basket is full of medicinal herbs. "Maybe we can find the legendary elixir that can cure all diseases."

In the Ningyun Mountains, people often pick elixirs from hundreds of years ago and sell them to the city to make a fortune.

Moo!

The big black cow was running around like a wild animal, and it knew many medicinal materials. I had to admire the power of knowledge, and its mind was much clearer now.

"But don't go too deep. I heard that there are monsters, but they are different from ordinary beasts."

Chen Xun said nervously, "If we meet any immortal cultivators again and they don't like us, they will kill us."

Moo!

Dahei Niu responded, "I understand."

"what!!"

A miserable cry came from the jungle, startling countless birds in the forest. Chen Xun subconsciously put on a bandit's turban. The big black cow stopped and they looked at each other.

"There is a monster!!"

Several people ran from a distance and kept shouting in panic. They were all stunned when they saw Chen Xun's turban, and then shouted: "Run quickly, monster...monster."

"Old Niu, run quickly."

Chen Xun was frightened and panicked. He rushed forward with the big black bull. He heard a roar from behind, and a beast that looked like a wolf and a tiger chased after him madly. Its body was bigger than a tiger, and its eyes were extremely scarlet.

"Go ahead, what kind of look is this? It's so scary."

"Moo! Moo!"

Chen Xun and Da Hei Niu were frightened and screamed. Living for so many years was really an eye-opener.

One person and one ox were not slow at all. Countless dead branches were trampled and broken, turning into two gusts of wind. The people behind them were shocked, how damn fast they were running.

The monster became angry, its eyes became scarier and its saliva splashed to the west. It liked prey that ran fast.

"Ah!! Here it comes!"

Several people screamed, and one person was so frightened that he fainted. However, the monster actually passed them and chased the man and the cow.

"What are you doing? Are you sick?!"

Chen Xun's pupils widened. The monster was chasing them first, much faster than the wild beast.

"Moo! Moo!" The big black bull charged wildly, sweating slightly on its head. This beast was too terrifying.

"Moo~~!" There was a loud bang!

The big black cow accidentally ran in too much panic and hit a giant tree first. The giant tree was cracked by the impact and began to tilt, and even the roots were about to be knocked out.

"Old cow!" Chen Xun stopped and shouted, his eyes full of anxiety, and he quickly went to check its head.

"Moo~~"

The big black cow was a little dizzy, but it was fine. It was just a little bruised and it rubbed against Chen Xun.

Roar!

The monster was about to catch up at this time, with excitement in its eyes. This was the first time it had encountered prey running so fast.

Chen Xun and Da Hei Niu were surrounded. They stood together, their eyes full of panic. The appearance of this monster was too terrifying.

"It's over, old cow."

Chen Xun said in a trembling voice. He was still holding the bull's head in one hand. The big black bull's pupils were trembling slightly and its hooves were trembling. Could it be that the road to immortality would stop here.

The monster beast kept drooling and circling around them. These two prey were so timid that it had no vigilance in its heart.

The monster suddenly leaned over, its eyes were bloodthirsty, and it drooled a drop of saliva on the spot, then fiercely charged towards Chen Xun.

Its eyes showed an excited killing light. At this time, they were close at hand. Suddenly its expression changed. The human seemed to be no longer afraid, but became extremely calm.

A violent cyclone appeared on the ground, and Chen Xun turned into an afterimage. The speed was so exaggerated that the monster's eyes could hardly keep up, and it looked horrified.

"Although your Excellency is very strong, you are not strong enough for me to use the second mountain axe."

Chen Xun was already behind it, walking with his back to it, holding a bloody mountain ax in his hand, and the bandit's hood only revealed a cold look in his eyes.

Suddenly, there was a sharp pain in the monster's abdomen. It fell to the ground and howled in pain, with blood flowing all over the floor.

The big black bull suddenly bounced, and the black bull hit the top! Bang, a big hole was made in the ground, and the demon beast's intestines were squeezed out. It was too dead to die.

Chen Xun was ruthless, scoff! Blood splattered again.

"That's it?! Ah, that's it!"

"Moo! Moo!"

"I'm trying to scare your dads. Why isn't the dog barking?"

"Moo!"

One person and one bull whipped the corpse crazily, venting their anger wildly, spitting everywhere. They were really frightened by this monster.

There is a big pot, and as soon as the water boils, motherfucker, let’s start the feast!

"Old Niu, we are lucky this time. This monster is capable of sorcery, such as the two heavens of ice and fire."

Chen Xun thought for a while, but he had heard the legend of monsters in the city, "Only immortal cultivators can kill those, but the meat is so delicious."

"Moo~~"

The big black cow screamed with happiness. It was so delicious. It was the first time it had eaten such fragrant meat.

After one person and one cow finished eating, they quickly covered up the traces, packed up the uneaten meat, and even filled in the holes.

Chen Xun was very careful this time and arranged the scene of the crime. The ashes of the monster were scattered to the west, and everything seemed like nothing happened.

They ran far away and found a jungle area where there were fewer wild animals.

"Both the old cow and the cunning rabbit have three burrows. We can't be weaker than the rabbit. Let's dig out!"

"Moo!"

Being strong is good. Chen Xun is proficient in various field digging skills, such as laying foundations and digging clay. He will never sleep on the ground.

Finally, Chen Xun carefully moved the boulder to seal the top, leaving a slight gap. It was also covered with turf and fallen leaves, so that no one could tell that there was a hole inside.

The candlelight in the cave lit up, and the whole world was safe.

"Comfortable."

"Moo!"

Chen Xun leaned on the big black bull and fell into deep thought. The world was full of dangers after all, especially the monsters today, which almost scared them to death.

After hesitating for a long time, he took out the book Mr. Sun gave him - "Qi Refining Technique"
