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

Half a day later, Chen Xun and Da Hei Niu stood far outside Panning City, familiar yet unfamiliar.

People were still coming and going outside the city gate, and carriages passed by, guarded by hard-blooded soldiers.

But the city wall had been renovated several times, and it was no longer what they remembered.

They just looked up for a few times, and walked towards the city step by step without any wavering in their eyes.

As soon as we entered the city, there were buildings and pavilions everywhere, and red lights hung high, but the streets had changed drastically, and shouts continued to reach our ears.

"Old Niu, let's walk around first."

Chen Xun quietly spread his consciousness, and pedestrians came into view on the streets, "Haha, I saw the candied haws seller."

"Moo~" The big black bull slapped Chen Xun and told him to leave quickly.

They were walking and walking on the street. Chen Xun held two bunches of candied haws in his hand, with disappointment in his eyes and a bit boring to eat.

The big black cow tasted more delicious every bite, and I felt that the candied haws in Panning City was still more delicious.

Pedestrians passing by quietly pointed behind me, shaking their heads with chuckles. How could a cow eat candied haws?

They walked from day to night and came to a remote street, where the shouting was obviously much quieter.

There are a few teahouses and taverns, but no blacksmith shop. Occasionally, small groups of people from all walks of life pass by.

"Moo?" The big black bull was startled and looked to the west. Where is their shop? ! Not sold!

"Old Niu, what are you thinking about? This is the mortal world, there are laws, and they should be taken back."

Chen Xun laughed loudly and walked forward, "Go and have a look."

"Moo~" Da Hei Niu snorted, his mind was a little confused, they didn't sell the shop...

Blue and white teahouse.

Chen Xun and Da Hei Niu stood outside for a long time. This place seemed to have been Mr. Sun's blacksmith shop.

"Master! Please come inside. I will tie this black cow outside for you."

At this time, a smiling boy walked out of the teahouse and said, "You will never find a better teahouse on this street than this one."

The boy has been standing in the teahouse observing for a long time. This boy definitely wants to come in.

"Yeah, I can't find it anymore." Chen Xun looked at him, a smile gradually appeared on his lips, "We'll come back next time."

"Moo~" The big black cow took a deep look at the teahouse.

"Ah? Okay, okay." The boy's heart sank, but he still greeted him warmly.

He looked at the two departing figures and muttered angrily, wasting time.

Panning City, south.

There are still many medical clinics here, and most of the people are suffering from sorrow, and many people come from outside the city to seek medical treatment.

But there is a famous family in Nancheng, with a history of thousands of years, a family of doctors, Ning!

It was rumored that there was green smoke coming out of the ancestral graves of the Ning family, and that there were several imperial doctors from the ancestors, and some members of the clan migrated to the imperial dynasty.

What the hell!

Chen Xun and Da Hei Niu inquired all the way, and finally his eyes showed a look of ecstasy. With Master Ning's blessing, the Ning family deserves to be prosperous!

Pingtai Medical Clinic.

This medical center has occupied a large area and has become the largest medical center in Beicheng.

There are also two sage hands from the Ning family, Ning Yuanru and Ning Chongwan, who are in charge of the medical center. Their wonderful skills in rejuvenation have already spread to the surrounding cities.

The couplet from that year is still written below the plaque of the hospital.

The first couplet: I hope everyone in the world is well, the second couplet: Why worry about the medicine on the shelf producing dust. Hengpi: Peace in the world.

Today, Ning Yuanru and Ning Chongwan are sitting on the tea table in the room talking about medical skills.

"Brother, I'm afraid this disease is related to the medicinal properties of the medicinal materials, and the difficulty is not in medical skills."

Ning Chongwan spoke softly. She was dressed in a white dress. She looked delicate and had a faint medicinal fragrance all over her body. Looking from a distance, she gave people a sense of tranquility.

"Third sister, don't be anxious. If we start with medicinal materials, how can the common people bear such a heavy burden?"

Ning Yuanru raised his hand slightly to pick up the tea cup, his manner was gentle and elegant, and his words were as heart-warming as the first blowing spring breeze.

His eyebrows are long and bright, and the brilliance in his eyes is like the slight glimmer on jade. They look soft, but are actually extremely tough.

Ning Chongwan sighed softly and looked through ancient books, wanting to see how those ancestors overcame difficulties and find some wisdom from them.

At this moment, the tea in their hands rippled, and their expressions changed drastically at the same time.

A man and a cow appeared in the room silently!

"who?"

Ning Yuanru and Ning Chongwan's eyes were focused. Although there was panic in their eyes, they had seen many strong winds and waves, so they were still calm.

This kind of skill is at least the existence of a martial arts master. It is probably because the Ning family outside has offended someone.

"Don't panic, you two." Chen Xun smiled lightly, and a few wisps of breeze blew through the room.

The breeze blows everywhere and everything is renewed, and the tables and chairs in the room take on a new look, immortal!

The two of them stood up in shock. They were frightened and quickly lowered their heads and handed over their hands:

"Ning Yuanru, I have seen an immortal."

"Ning Chongwan, I have seen the immortal."

They looked more and more horrified that they had met the legendary immortal, but they were also inexplicably uneasy, not knowing what the immortal meant by coming.

"Moo~" The big black cow barked softly and sniffed it twice. It had a strong medicinal scent, which was the same as the smell on Chen Xun's body.

"No need to be polite, we just came to see the Ning family."

Chen Xun waved his hands and held them up, "The ancestors of the Ning family had an old relationship with me."

Ning Yuanru was stunned after hearing this. His ancestors were actually related to immortality. He said respectfully: "Immortal, please take a seat. Third sister, please go and take out the tea brought back from the imperial city."

"Sit down for a moment, Immortal. I'll get ready right now." Ning Chongwan's eyes sparkled, he saluted, and he hurriedly walked out.

There were only two people and one cow left in the room. Ning Yuanru felt a little embarrassed. After many years of self-cultivation, he was like a child in front of Chen Xun.

"It seems that the Ning family has been doing well over the years."

Chen Xun sat on the main seat and looked at Ning Yuanru with a smile, "I just heard you talking about it. If you have any pharmacological questions, you can ask me."

"Immortal, I dare to ask you and the ancestors of the Ning family..."

Ning Yuanru's lips were dry, but he still asked the most curious question in his heart, "I hope the immortal will not misunderstand. How can I disturb you at will?"

How dare he really ask the immortal any pharmacological questions? Probably the things he said were not from the same world as him.

"Ning Si, you were my master."

There was a little pride in Chen Xun's eyes, "Being able to see that the Ning family has been passed down to this day, I think his spirit in heaven will also feel gratified."

Ning Si? !

Snapped!

Ning Chongwan had just put the tea at the door. When he heard the name, his hand shook and he knocked the teapot to the ground, with severe shock in his eyes.

Ning Yuanru's pupils shrank violently, his heart was filled with tears, and cold sweat soaked his back in an instant.

This name is absolutely ancient, so old that you can see this name just by turning over a few pages of their family tree...

Although the two of them had heard that immortals could live hundreds of years longer than mortals, there was no way they could live this long!

Isn't this a real old monster...

But this person's face was much younger than theirs, and the two of them seemed a little frightened as they stood there.
