Chapter 191 Arrival at the Underground City

Lightning bead?

Lin Chen's heart moved slightly.

The thunder bead is a special magic weapon that can weaken the thunder tribulation to a certain extent and at the same time purify the pure energy in the thunder tribulation.

Use pure energy to temper the monk's body and soul. The principle is completely different from that of lightning rods and the like.

If used in thunder tribulation, it would indeed be a big help.

Thinking of this, Lin Chen asked:

"Fellow Taoist, how many spiritual stones does this thunder bead have?"

"One hundred thousand spirit stones." Xie Huaying interrupted at this time, staring at Lin Chen with her beautiful eyes.

"This fellow Taoist, you look familiar. We seem to have met before?"

Lin Chen blinked after hearing this and said, "Girl, your way of striking up a conversation is a bit old-fashioned."

"Ah?" Xie Huaying was stunned for a moment, then her pretty face turned red and she said nothing more.

She really felt that there was something familiar between Lin Chen's brows, as if she had seen him somewhere.

But when Lin Chen interrupted her, she didn't have the intention to ask.

Lin Chen took out a bag of spirit stones and handed it over.

"There are a million spirit stones here, give me ten."

Xie Huaying nodded after hearing this and handed over a jade box containing ten thunder beads.

"This thunder bead is usually kept in the jade box, don't take it out easily."

"When the thunder tribulation comes, consuming the thunder-inducing beads can improve the body tempering effect of the thunder tribulation..."

Xie Huaying reminded him, and then handed over a black jade pendant.

"Fellow Taoist has considerable financial resources. If you want to purchase rare resources in the black market of the tunnels or Tiandao City, you can show this jade pendant."

Lin Chen nodded after hearing this, accepted the jade pendant, and turned around to leave.

After Yang Cai'er greeted Xie Huaying, she followed Lin Chen and left.

Walking on the road, Lin Chen asked intentionally or unintentionally:

"Cai'er, how did you know about this black market?"

Yang Caier thought for a while and said:

"Actually, the guides in the city know something about it. This black market is not a secret..."

"And I like to come to this sweet water shop to drink honey water...I got to know Sister Hua as soon as I went there."

Lin Chen nodded after hearing this, and Yang Caier's words deepened his suspicion.

"Senior Zhou, it's still early in the morning, shall I take you to Shangcheng District for a walk?" Yang Cai'er volunteered.

Lin Chen nodded and took Yang Cai'er to the upper city with his flying sword.

…

Until the evening, Lin Chen had roughly explored the entire upper city area.

"Senior Zhou, it's late today... If you have any questions, senior, you can come to me at any time."

Yang Caier stretched out her right hand, revealing the white ring on her finger.

"Senior, the residence certificate of Humanity City also has the effect of sound transmission. As long as it is within a hundred miles of the city, it can be used, similar to the sound transmission jade slip."

"Cai'er's is a temporary residence certificate. I used a hundred spirit stones to upgrade the messaging function, but my senior's permanent residence certificate directly has this function."

Saying that, Yang Cai'er touched Lin Chen's black ring with her ring.

As expected, Lin Chen sensed that there was an extra node in the ring that he could contact at any time.

Lin Chen felt miraculous when he saw this. In the Righteous Alliance, even the monks in the later stages of foundation building might not be able to afford the communication jade slips.

But in this humanitarian city, it seems that communication has become the means of contact for the public.

"However, this ring communication is issued by Humanity City after all...it may be secretly monitored."

"We can still talk about some basic information, but if it involves confidential information, we must not transmit it through the ring."

Lin Chen thought to himself.

Then he took out a bag of spirit stones and handed it to Yang Cai'er.

"Thank you very much for what happened today. I'll come back to you if I need anything later."

Yang Cai'er took the spirit stone bag, and then a look of surprise appeared on her face.

"Senior, this...there are too many spiritual stones!"

"Cai'er doesn't need so much..."

The bag of spiritual stones that Lin Chen gave to Yang Cai'er contained exactly ten thousand spiritual stones.

It was enough for her to obtain permanent residence in Humanity City.

Just leading the way is naturally not worth so many spiritual stones.

But the three medicinal ingredients of the Infant Forging Pill helped Lin Chen a lot and were worth ten thousand spirit stones.

Lin Chen shook his head and said:

"Just keep it. If I have anything to do later, I may have to trouble you..."

After saying that, Lin Chen turned into a ray of light and disappeared on the spot.

…

In the evening, Lin Chen returned to the inn alone.

After setting up a formation to isolate his spiritual consciousness, Lin Chen glanced at the countdown on his arm.

"10:56."

There are less than 11 hours left before it’s time to return to Blue Star next time.

Lin Chen took out the resources he purchased today.

In addition to refining the medicinal materials for the Infant Training Pill and lightning protection beads, Lin Chen also bought many other medicinal materials and equipment.

The raw materials in Humanity City are undoubtedly of much higher quality than those in the Righteous Alliance.

Lin Chen could even buy a lot of high-end equipment for making treasures.

Of course, the price is also very expensive...

"Guangyuan Town and Changchun Shanfang City are only eight hundred miles apart, but there is a price gap..."

"The distance between Humanity City and Humanity City is nearly 100,000 miles, which is an insurmountable distance for Qi Refining and even Foundation-Building monks... Only Jindan monks can reach Humanity City from Yan Lai Country..."

Lin Chen shook his head.

It took him ten days to get from Yanlai Realm to Humanity City. This was because his escape speed was fast enough.

But for foundation-building monks, this time will be extended to one year or even several years...

It was so far away, and there were so many dangers along the way, that Lin Chen alone encountered several groups of robbery cultivators.

Therefore, the chances of a foundation-building cultivator coming to Rendao City are slim, not to mention a Qi-refining cultivator...

And Dao City is still more than 100,000 miles away from Rendao City... and even farther away.

Only some large chambers of commerce, such as the Guangyuan Chamber of Commerce, will travel through mountains and rivers to trade in Qingzhou.

"Well, it's rare to travel so far this time, I should buy some more medicinal materials, exercises, etc..."

Lin Chen touched his chin, and the entire high-level martial arts world behind him was crying out for food, waiting for him to bring back valuable resources.

However, it would be better to go back and ask the think tank what specific ones to buy.

"It's best to bring the medicinal materials for the infant-forging pill back to Blue Star for cultivation. If everything goes well... within a few years, you can get a lot of infant peach fruits and heart-guarding grass, and then you can break through the Nascent Soul stage."

Lin Chen thought silently.

This time he went out to form an infant, and he needed to prepare a lot.

The infant-forging pill and the lightning-inducing bead have been found, so the next step is to find the lightning-avoiding pill.

In addition, the more elixirs and magic weapons such as calamity shields that help overcome the heart tribulation, the better.

"I still have 8 million spirit stones on hand, I don't know if it's enough..."

Lin Chen put all the supplies into the nano bag and waited quietly for the time of crossing.

...

Great Xia Kingdom, Martial Arts Palace.

After Lin Chen returned, he handed the supplies to Wang Lishan, and then asked him to prepare a list, which was roughly the supplies that the country needed to purchase.

After he returned to the world of immortal cultivation, he could just make a large purchase along the way.

After doing all this, Lin Chen soaked in the alchemy room.

Lin Chen's heart moved slightly, and a ball of green liquid split into dozens of strands and entered the alchemy furnace.

Then he added many auxiliary medicines and started to refine the pills...

After an hour, hundreds of round pills flew out.

Lin Chen picked and chose, and selected more than a dozen high-quality jade marrow qi-enhancing pills from them.

"Yes, on average, ten kilograms of chalcedony can produce hundreds of chalcedony qi-enhancing pills..."

"The temperature and timing of the instrument are almost adjusted to the best. It's just that the rate of top-quality pills is still a bit low."

Lin Chen nodded slightly and put away the top-quality chalcedony qi-enhancing pills.

He would naturally give priority to the ones with good quality.

The remaining chalcedony qi-enhancing pills are also valuable and beneficial to cultivation. They are left for the talented cultivators of Daxia Kingdom to take.

After refining pills for three full days, Lin Chen was able to control the rate of top-quality pills to about 10%.

He refined hundreds of top-quality chalcedony qi-enhancing pills and kept them for later use.

This can help him break through to the Nine-Turn Golden Pill faster.

After that, Lin Chen spent another three days refining hundreds of chalcedony bone-forging pills.

After refining the two pills, Lin Chen gave the pills to the country and asked them to help test the effects of the two pills.

In Lin Chen's view, the chalcedony bone-forging pill is definitely a martial arts treasure that is not inferior to the marrow-washing pill.

However, the specific effect still needs further experiments.

...

Soon, a month passed.

Lin Chen stayed in Humane City for a full month and obtained the pass to Didao City.

During this period, Lin Chen also saw many monks from the Demon-Subduing Temple in the upper city, but unfortunately he did not see Li Tianhan.

That day, Lin Chen felt that it was time to go to the next pass, so after saying hello to Yang Caier, he left Humane City.

After staying in this city for only one month, Lin Chen did not have too many concerns, and did not even make new friends.

He just purchased a lot of medicinal herbs and refining materials, spending nearly one million spirit stones.

After doing all this, Lin Chen flew towards Didao City.

After another three days, Lin Chen flew 30,000 miles and finally arrived at Didao City.

The layout and rules of the three cities in the Dao are roughly similar.

Didao City is also divided into upper and lower urban areas. Lin Chen spent 10,000 spirit stones to buy a permanent residence permit for Didao City.

First, he obtained the pass to Tiandao City, and then Lin Chen went to the black market in the lower city.

After showing the jade pendant, Lin Chen successfully met the person in charge of the black market in Didao City.

"My fellow Taoist, what do you want to buy?" the person in charge asked.

Lin Chen got straight to the point: "Thunder God Pill, the spiritual shield needed to survive the thunder tribulation, do you have it here?"

The things Lin Chen wanted to buy were too characteristic, and the person in charge looked at Lin Chen deeply and said:

"Yes, an ordinary Thunder God Pill costs 500,000 spiritual stones, and a medium-grade one million spiritual stones..."

"As for the spiritual shield, it depends on the power, ranging from 100,000 to 1 million spiritual stones."

After hearing this, Lin Chen smacked his lips. The cost of forming a baby was really too high.

Apart from other things, just preparing the most basic infant-forging pills, thunder god pills, magic weapons, etc., at least millions of spiritual stones are needed.

Whether the baby formation is successful or not, millions of spiritual stones will be wasted. How can this ordinary Jindan cultivator afford it?

However... Lin Chen could just buy the herbs and make them himself.

Lin Chen pondered for a moment and said:

"Do you have the herbs for making the Thunder God Pill?"

The man nodded and took out two purple spiritual herbs.

"Thunder Spirit Grass, one hundred thousand spiritual stones..."
