Longevity: Never leave the mountain until you are invincible

Black Rock City.

An extremely ordinary city in Dayan Kingdom is famous for its rich black black stones.

Weapons made of black black stone are hard and sharp, and can be regarded as magical weapons. They are deeply loved by the officials of the Great Yan Kingdom and martial arts people.

As a result, Black Rock City has spawned a series of businesses surrounding Black Black Stone weapons, and most of the people in the city are engaged in related things.

There are more than a thousand blacksmiths in the city.

Many mine owners outside Black Stone City send the mined black black stones to the major blacksmith shops in the city for processing, and process them into various weapons on the spot, and then sell them out.

Many knight-errants would come directly to Black Rock City and ask the blacksmiths in the city to build weapons they wanted.

Because there is a lava vein under Blackstone City.

It is easier to forge black black stone with the lava fire generated by the lava veins.

A blacksmith shop in the city.

From the outside, this blacksmith shop is not much different from other blacksmith shops.

A shaky signboard hangs at the door, and some well-made weapons are displayed in the store. A waiter is busy greeting customers.

In the forging room in the backyard, Chu Chen sat cross-legged. The five-qi alchemy furnace was placed on the lava fire, and he continuously fired out mana, fusing many elixirs in the alchemy furnace.

"Turn on the furnace!"

After a long time, Chu Chen's expression condensed and he used the magic formula.

The lid of the Five Qi Dan Stove was opened, and a faint medicinal fragrance floated out.

"Thirteen elixirs are made, of high quality. The refining method of the body tempering elixir has reached the level of perfection."

Chu Chen stretched out his hand and made a move, and the pills in the Five Qi Pill Furnace flew out and fell into the medicine gourd in front of him.

After a brief inspection, a smile appeared on his face.

Since leaving Fengqi City, he came to Blackstone City and bought a blacksmith shop.

On the surface, he bought this blacksmith shop to do the business of forging black black stone soldiers. In fact, he wanted to make elixirs with the help of the lava fire under Black Stone City.

The Body Tempering Pill is a body-training elixir recorded in the Five Qi Pill Sutra, and it has a considerable improvement effect on practicing the Soul-Seizing Body Training Sutra.

As early as in Chiyanfang City, Chu Chen tried to refine this elixir in the dream world. It was not until a few months after moving to Black Rock City that he began to refine the body tempering elixir in the outside world.

"Unfortunately, the fire of lava can only be used to refine first-grade elixirs such as the Body Tempering Pill, and cannot be used to refine second-grade or higher elixirs such as Qinggang Body Washing Pill."

With Chu Chen's magic power, the Five Qi Pill Furnace slowly shrank and fell into his sleeve.

Alchemists in the world of cultivating immortals divide the grades of elixirs into grades one to nine, with grade one being the lowest and grade nine being the highest. Each grade is further divided into four levels: low-level, middle-level, high-level, and top-level.

For example, Jing Qi Pill and Nei Qi Pill are first-grade low-level elixirs, Gathering Spirit Pill is a first-grade mid-level elixir, and Body Tempering Pill is a first-grade high-level elixir.

Lava fire, a flame that is not even a spiritual fire, can only be used to refine first-grade elixirs, and cannot be used to refine second-grade or higher elixirs.

In other words, if Chu Chen wants to refine a second-grade or higher elixir, the prerequisite is to condense the Dantian spiritual fire.

Chu Chen has no shortage of techniques for condensing spiritual fire, which are included in the Five Qi Dan Sutra. However, if he wants to condense the spiritual fire in his Dantian, he must have the cultivation level of the Foundation Establishment Stage. He is still a long way from this realm.

He won't consider condensing the spiritual fire in his Dantian for the time being, so he won't be able to refine second-grade or higher elixirs.

Otherwise, Chu Chen would have already started trying to refine second-grade or higher elixirs.

No matter how difficult it is to refine the second-grade elixir, Chu Chen can always refine it if there is a dream world, and after working hard for a while, the success rate will be increased to an extremely high level.

The restriction of Dantian Spiritual Fire forced him to give up this idea temporarily.

"The elixir in my body has been exhausted. When will the war between Chiyanfang City and Demon Nest end?"

Chu Chen sighed.

At this time, five years have passed since he left Chiyanfang City.

After practicing the Soul Seizing and Body Training Sutra and refining the Body Tempering Pill, all the elixirs he brought from Chiyanfang City were consumed.

If he does not return to Chiyanfang City, he will face a situation where there is no elixir available.

However, the news he heard through the channels of Longmen Escort Bureau last month still did not reveal that merchants from Hanbei Kingdom passed through the Hengduan Mountains and came to Dayan Kingdom.

"Owner!"

At this moment, a white shadow sprang out from the corner of the room. It was as fast as a white lightning and fell on Chu Chen's shoulder in an instant.

Chu Chen turned around and saw that it was the white mouse that had been sleeping.

Compared with before, the size of the white mouse has grown again, its fur has become whiter and brighter, and the fluctuations of evil energy coming from its body have reached the seventh level of Qi training.

It had eaten a lot of Chu Chen's spirit-gathering pills and cold spring nectar. While sleeping, Chu Chen used magic power to cleanse its body from time to time.

This breakthrough is not surprising.

The little white mouse was staring at the Body Tempering Pill with eager eyes.

"You greedy little guy."

Chu Chen laughed, took out a body tempering pill and handed it to the little white mouse.

"Thank you, Master."

The little white mouse took the Body Tempering Pill, took a few mouthfuls, and swallowed it like a jujube.

After patting his belly, a satisfied smile appeared on his face, and he curled up comfortably into the small wooden box that Chu Chen took out, refining the power of the body tempering pill.

Chu Chen put the small wooden box on his waist, waved his hand, and the iron-making furnace nearby fell on the lava fire.

He picked up a few black iron stone weapons that had been forged in advance, walked out of the forging room, and came to the blacksmith shop.

"My boss."

The waiter in the shop came over quickly.

"Um."

Chu Chen nodded, handed the black iron stone weapon to the waiter, chatted with a few regular customers, and then left the blacksmith shop.

When he returned to the blacksmith shop, he had a letter in his hand.

The letter came from Longmen Escort Agency, which recorded information about the Hengduan Mountains.

"Several teams of merchants from Hanbei crossed the Hengduan Mountains and came to Dayan?"

Chu Chen's eyes lit up when he saw the first line of the letter.

"Is the battle between Chiyanfang City and the Demon Nest finally over?"

He continued to read.

Just a few days ago, a team of merchants from Hanbei came to Dayan, and several teams of merchants arrived in succession in the following days.

It depends on the situation, and more merchants from Hanbei will arrive in the future.

Five years ago, the trade routes between Hanbei and Dayan were cut off, and many transactions between the two countries were forced to stop. The trade routes were opened again, and merchants from Hanbei naturally flocked to continue the transactions that had not been completed before.

This also means that the Hengduan Mountains have finally returned to peace.

"The situation in Chiyanfang City is unclear, and we need to investigate further."

Chu Chen pondered for a moment, and then came up with an idea, which was to let the little white mouse go to Hengduan Mountains to check.

If the little white mouse did not wake up, he could only settle for the second best, and train Zhao Shaodang as a cultivator, and let him go to Chiyanfang City to check the situation.

Now that the little white mouse has woken up, it is more appropriate for the little white mouse to go.

First, there is no possibility that the little white mouse will deceive him.

Second, after the little white mouse broke through the seventh level of Qi training, its speed is not worse than that of the cultivators of the eighth level of Qi training, and it is most suitable for exploring information.

"Little white mouse, I have a task for you."

Chu Chen immediately asked the little white mouse to go to Hengduan Mountains.

The little white mouse was very fast, and returned to Black Stone City that night, bringing back news about Chiyanfang City.
