Before the Qin Empire was established, the imperial capital already existed, but it was not an imperial city at that time.

Today, the royal family has been working here for thousands of years.

Strictly speaking, the inner city is the real imperial city, while the outer city was expanded later and has a history of less than a thousand years.

After a moment, Lin Yun was convinced by the fluctuations coming from his feet.

It is indeed very similar to the textures I have mastered, but the difference is much greater.

It is thicker and more complex, giving people the impression of a vast sea with mountains rising up.

"What's the matter?"

Li Wuyou saw Lin Yun's strange expression and asked.

Lin Yun thought for a while and said: "Have you ever felt the fluctuations coming from under your feet? Although it is very secret, you can really feel it with every step you take."

Li Wuyou smiled and said: "I thought what were you thinking? This is an ancient city defense formation that permeates the entire inner city of the imperial capital, allowing the royal family to firmly control the imperial capital. In this inner city, the Great Qin Imperial Guards

, has absolute strength, even beings above the Xuanwu realm do not dare to provoke casually, just because of the existence of this formation."

"clear."

It has to be said that the inner city is indeed more strict than the outer city.

Warriors walking on the street can hardly see the existence of Houtian realm. With an occasional glance, you can easily see the masters of Xuanwu realm.

Or, to be more precise, in the inner city of the imperial capital.

It's too common for people in the Xuanwu realm to be considered masters.

After finishing their shopping, the two of them found an inn to stay in the inner city.

Although the orifices have been opened and the breath can be used as food, the desire for food and appetite is still there.

In the grassland of Mobei, the two of them slept in the open air. The conditions were very difficult, and they couldn't help but eat a big meal when they entered the inn.

When it was time to rest, Lin Yun closed the door and began to study the bamboo slips.

The light on his fingertips flickered, and he carved complex lines on the floor of the room.

After half a stick of incense, many lines and auras flickered, and they all seemed to be vibrating with life.

Nowadays, these lines are not carved as easily as the owner of the bamboo slips, but they are not difficult to understand.

Hundreds of lines flashed in front of him one by one.

After thinking for a while, Lin Yun took out an innate pill and placed it in the center of many lines.

Ever since he was able to condense the scattered basic textures into more complex and complete textures, Lin Yun has been thinking about imprinting those complete textures on the elixir.

On the way here, I tried more than ten times, but basically ended in failure.

"It should be successful this time."

Although there have been many failures, there has been considerable progress each time, and now Lin Yun has a lot of confidence.

As soon as he finished speaking, Lin Yun stretched out his hand.

Hundreds of extremely complex and unrelated lines, interlocking with each other as Lin Yun's fingers pulled them, fit together perfectly like a puzzle.

At first glance, it looks like drops of water connected together, and then continuing to compress and condense.

boom!

When it was finally integrated into the Xiantian Pill, the entire pill burst into flames and made a crackling sound.

The innate spiritual energy in Lin Yun's body surged thousands of miles away like a flood bursting from a dam.

His face suddenly turned pale, and the purple kites in his dantian couldn't help but spread out. The thick innate spiritual energy was like surging spring water, constantly spurting out.

Almost all the pure spiritual energy poured into this burning innate pill.

After a while, Lin Yun was sweating profusely, as if he was going through a life and death battle.

Not only was most of his spiritual energy consumed, his spirit was also exhausted.

Hiss!

White smoke swirled around the Xiantian Pill, and there were many gray impurities in the scattered smoke.

"Did it succeed?"

Wiping the sweat from his forehead, Lin Yun looked solemn and unsure.

After the white smoke cleared, he walked up cautiously, and a wisp of shiny silver-white elixir appeared in front of Lin Yun.

"If I remember correctly, the Xiantian Pill should be vermilion red."

Confused, Lin Yun reached out and took a sip, placing the silver-white elixir in the palm of his hand.

So heavy!

Immediately, I felt that this elixir was about ten times heavier than before.

What surprised Lin Yun even more was that at the bottom of the elixir, there was a tiny concentrated purple iris flower.

It's just that this purple irises flower is a little rough and not so delicate.

But even in such a tiny situation, you can still see that the general outline is a purple kite flower.

Count carefully, no more, no less, exactly thirty blooming petals.

"Why does the complete pattern turn into a purple kite after being branded? It's interesting..."

A smile appeared on the corner of Lin Yun's mouth, and he found that the patterns contained in the bamboo slips became more and more mysterious.

Playing with the silver-white Xiantian Pill in his hand, Lin Yun thought of a deeper mystery.

He knows nothing about alchemy.

But now, he has truly recreated an elixir using the special patterns of the owner of the bamboo slip.

If this pill works well, it may prove something.

The process of refining the alchemy is not that important, the real finishing touch is the mysterious lines.

There was only one question before him, whether to take this silver-white Xiantian Pill.

It would be weird if you don’t eat it!

For others, they may hesitate for a moment and dare not make a rash move, but for Lin Yun, he must be decisive when it is time to be decisive.

The silver-white Xiantian Pill is swallowed into the mouth, swallowed gently, and then falls into the abdomen.

Compared with other elixirs that melt in your mouth, this elixir is just like a stone and does not melt.

Moreover, not even a trace of the medicinal power has been released.

If Lin Yun hadn't known that it was an innate pill, he would have thought that he had swallowed a stone.

"how so?"

Just when Lin Yun was amazed, the silvery-white elixir fell directly towards the purple kite flower in his dantian.

With a thought in his heart, he quickly opened the purple iris flower and swallowed the silvery white pill.

Then he sat cross-legged and quietly moved his sword skills.

Wow!

Once the technique is activated, the silver-white elixir inside the purple iris flower immediately emits rich and powerful medicinal power.

The astonishing and surging medicinal power is like a volcanic eruption, making a loud noise inside the purple iris flower.

Most of the spiritual energy consumed just now was restored in an instant.

It's not finished yet, most of the silver-white innate elixir is still in dissipation.

His innate five-aperture cultivation, which had been stagnant for a long time, actually started to loosen under the impact of this elixir and began to grow slowly.

Lin Yun's heart was suddenly shocked. This... this is just an innate pill!

In the past, Lin Yun's practice of refining Xiantian Pills was just like eating and drinking water. There were not dozens or hundreds of pills, and if he wanted to use them, he would not even think about it.

The Xiantian Pill is very important, just like a mortal needs to drink water. The cultivation of the Xiantian realm is basically inseparable from the Xiantian Pill, and it must be consumed every day through hard work.

It's not important, it's not important, it's just a basic elixir, it has no other magical effects.

But now, this silver-white Xiantian Pill completely overturned Lin Yun's thoughts.

So pure and pure that it can be perfected by the exercises

An elixir that is fully absorbed and does not escape at all is still a basic elixir.

After refining all the silver-white Xiantian Pill, Lin Yun was surprised to find out.

The purple kite flower quietly sprouted another petal, reaching thirty-one petals.

Ziyuan Sword Art broke through the fifth level bottleneck and advanced to the sixth level!

But it has not yet reached perfection. At the sixth level of perfection, it will take thirty-six petals to bloom.

Lin Yun opened his eyes, filled with unconcealable joy.
