After obtaining the Heart of the Earth Marrow, Lin Mu decided to return to the Ice Main Path and continue to explore the situation below.

The cave was still cold and biting, the wind was gusting, and there was not a trace of ice around the cave, but it was so cold that even the soul could freeze.

The Tailong Creation Code continued to operate, and the Dragon Yuan Force became active with the operation of the exercises, allowing Lin Mu to resist the invasion of the cold qi outside the body, and Lin Mu slowly infiltrated the Long Yuan Force out of the body according to the experience of his previous life, forming a thin layer of qi outside the body.

This is a kind of skill for the use of internal force after cultivating internal strength, which is not a skill, just a simple use of internal force, which is not a skill that a novice should have, and it is possible to learn it after many years of immersion in the use of internal force.

Lin Mu didn't have enough dragon yuan power to use before, but after taking the stone stalactite, long yuan power increased a lot before it could be used.

Studying the first layer of the Tailong Creation Codex, the dragon yuan force was formed for the first time, with 1000 points, and then promoted to the second and third layers, both increased by 1000 points of dragon yuan power, and after taking the stone stalactite, it increased by 250 points, a total of 3250 points of dragon yuan power, which can maintain a qi gang cover outside the body for a short period of time, like a golden bell jar to protect itself, which is one of the advantages of cultivating internal strength.

Inside the cyan qi gang cover, Lin Mu looked as usual, and ran quickly to the depths.

Is this Netherworld Spring really leading to the Yellow Spring River in the underworld?

I haven't heard of this information in my previous life, that is, after the system is updated, the player dies once and needs to enter the underworld to be reincarnated, is this underworld the other one?

I don't know how long I went, Lin Mu probably felt the amount of cyan dragon yuan power in his dantian, half of it had been consumed, and a small half of it needed to be left when he returned, so he would walk for a while, and if he hadn't finished yet, he would temporarily give up exploring.

This fork in the road is not straight horizontal, but continues to stretch underground and winding around. It was not shown on the map, so Lin Mu called it the Huangquan Secret Road in his heart.

After walking for a while, Lin Mu had the idea of returning, it was too deep and cold here. The frowns tightened and turned a curved path again, and suddenly a huge cold pool appeared, and a counterclockwise vortex appeared in the center of the cold pool.

The cold pool is about twenty zhang square, the cold mist of the cold pool curls, Lin Mu took a deep breath, his throat felt extremely cold and piercing, the coldness of this cave should be affected by this cold pool.

There is not the slightest freezing in the pool, and if someone sneaks into the pool, it should freeze instantly.

What surprised Lin Mu the most was the whirlpool that kept spinning, three zhang in size, deep and mysterious, although it rotated very slowly, but you must look at it, as if it had absorbed your soul into it.

Lin Mu walked along the edge of the cold pool, trying to get as close to the vortex as possible, thinking that a prompt would appear in the system.

It's a pity that Lin Mu walked around Hantan, and the system did not appear prompts, and the vortex did not change in the slightest, but kept rotating, which was really worrying.

When playing games, the system's prompts are very important and can be described as concise. Now there is no system prompt, so it must be judged according to the classic information.

Blessings, misfortunes lurk, Lin Mu thought of this sentence.

Since there was no system prompt, and Lin Mu did not have this experience in his mind, he did not waste time, Lin Mu resolutely turned around and returned.

Good or bad, as long as you are strong, you don't need to worry about it.

……

Returning to the Netherworld Secret Passage, Lin Mu saw Xu Yuan and the others who had recovered. After a rest, everyone is in good spirits, and they are no longer in a dazzle.

"Lord, you went down to see, how is the situation?" Xu Yuan asked.

"Nothing special, there is a cold pool in the depths of the fork, and there is a whirlpool the size of a zhang in the cold pool, which should be what you call the Netherworld Spring." Lin Mu smiled and said.

"It's very cold and biting in there, don't go in if you don't cultivate enough in the future, the tenth of the first month, with your cultivation, you should be able to go in, it's very simple there, I can't see the mystery, I need a professional teacher like you to investigate." Lin Mu shook his head and said.

"Okay, wait a minute, I'll bring a few backbones in, try to find a way to solve it, even if I can't completely eradicate the hidden danger, I have to try my best to seal it for a while." The indifferent look of confidence on Xu Yuan's face appeared again, and he had already come out of the tip of the horns.

"Good!" Lin Mu walked around, Feng Zhong and Chang Yin were also there, they should have heard the report.

Lin Mu didn't tell him about the situation of the Netherworld Secret Path before, because he was afraid that they would worry. Looking at their relaxed looks now, I know that I am thinking too much.

"By the way, on the tenth day of the first month, has there been any changes in the Colorful Spirit Silkworm Breeding Cave in Xufu Town because of the turning of the earth veins?" Lin Mu asked.

The colorful silk of Xu Fu Town is a special product, which is an accessory to obtain the nine-colored dragon silkworm back then, and Xu Fu and others brought it back.

The Colorful Spirit Silkworm Breeding Cave is another huge cave in the Netherworld Secret Passage, and they devour the mulberry leaves of the [Earth Spirit Mulberry Tree] that grows in this cave.

Colorful silkworms, need to be taken care of, otherwise there are no mulberry leaves to eat them, will form cocoons and butterflies, if there is a sufficient supply of mulberry leaves, they will continue to spit silk, will not turn into butterflies, very miraculous.

In the previous life, this secret path was called the Demon Disc Secret Path, which may have come from the colorful spirit silkworm turning into a butterfly.

"Everything is fine in the Colorful Spirit Silkworm Breeding Cave, and even because the aura has become richer, the [Earth Spirit Mulberry Tree] has grown more vigorously, the number of mulberry seedlings has also doubled, the mulberry leaves are more nutritious, and the colorful silk threads spit out by the Colorful Spirit Silkworm are deeper and more gorgeous. The changes in the cave are all good! ”

"Well, that's good news!" Lin Mu nodded, he has been busy recently, and he has not had time to inspect the new specialties in the territory, and he only looks at them from the paperwork report.

For the various industries in Xufu Town, Lin Mu was not particularly surprised, because they were too deep to make a fuss.

"Okay, you guys are busy first, I'll go back and ask Yuan Zhi to see if I can make a sacrifice." After Lin Mu talked with Chang Yin and Xu Yuan, he went straight to Yuan Zhi's residence.

Lin Mu obtained the nine-colored dragon silk, the stone stalactite, and the heart of the earth marrow, and the materials he currently has should be able to meet the conditions for casting divine weapons.

……

Seeing Yuan Zhi again, Lin Mu first greeted him, then mentioned the collection of materials, and asked if the conditions were met.

"Lord Lord, you have obtained so many strange and spiritual objects in such a short period of time, your luck is really good." Yuan Zhi was amazed to hear that he had collected so many rare items in these days.

"The materials are enough, you can make sacrifices, congratulations to the lord, you have finally obtained a divine weapon, and you will be invincible in the future!" Yuan Zhi praised it.

"Everyone, this sacrificial transaction, your merchant level should be upgraded, right?" Lin Mu said with a smile.

"Yes, it's no problem to go from the Yellow Rank to the Xuan Rank." Yuan Zhi's eyes were deep and his face was full of smiles.

"Sir, how should the sacrifice be carried out?" Lin Mu asked.

"Lord Lord, prepare the materials, and leave the rest to me!"

Lin Mu prepared the sacrificial materials: 300 pieces of nine-colored dragon silk, 300 units of eighth-order [Deep Sea Essence Stone], 1 drop of 10,000-year-old stone stalactite, 10 drops of thousand-year-old stone stalactite, three pieces of [Yinglong Dragon Scales], five drops of [Yinglong blood], and 20,000 gold coins of destiny (in exchange for the increased prestige of the Dao Nine Seals)

Casting Material:

Lin Mu's [Origin Essence Blood] :( Spirit, Lin Mu 100 Origin Attributes).

A drop of [Ying Dragon Essence Blood] (Spirit).

[The Essence of the Earth's Heart] (inscription carrier, obtained from the Huangquan Ice Cave in the secret passage).

[Ying Long Reverse Scale] (Spear Skull, Ying Dragon's reward).

[Ying Long Dragon Scale] two pieces.

100 units of [Nine Heavens Iron] (spear body, Ying Dragon's reward).

100 pieces of nine-colored dragon silk (spear tassel, obtained in the secret vault of Xu Fuzhen).

There is no problem with other materials, just the essence and blood of his own make Lin Mu very helpless.

The cast divine weapon needs to be condensed with the essence and blood of the owner to form a spiritual fit, and the soul and its spirituality can be inscribed, so that it can be used freely. This is Yuan Zhi's explanation.

"100 Origin Attributes! But I don't have so many origin attributes in me. Lin Mu wondered.

"It's okay, you can temporarily consume your own potential to condense your essence and blood, don't you still have a thousand-year-old stone stalactite, and when the time comes, you can take another drop to restore the potential of consumption. It is simply a consumption of potential essence blood, not a consumption of your potential ceiling, no need to worry, replenishing consumption is simpler than replenishing the upper limit. Yuan Zhi explained.

"For example, let's say you have 1000 potential essence blood, the upper limit is 1000, and now you need to consume 100 potential essence blood, so you only have 900 potential essence blood, but your upper limit is still 1000 points, but the amount is only 100 points less. Drinking a drop of the thousand-year-old stalactite can restore that 100-point amount. And this upper limit, if you want to increase it by 1 point, it is impossible to drink as much as you want to drink the thousand-year-old stone stalactite. The effect cannot be repeated. ”

When Lin Mu heard such a theory, he nodded, expressing his understanding, and at the same time, he also had a further understanding of the direction of his own strengthening.

"Okay, then the sacrificial rite begins!" After speaking, Yuan Zhi began to whisper, as if he was reciting some mysterious incantation, and as if he was inviting the gods......

After a while, a majestic aura enveloped this heaven and earth, and those sacrificial materials slowly turned into white light and disappeared, and those main materials were also wrapped in light, forming small light clusters.

At this time, a system prompt came from Lin Mu's ears:

"Congratulations to the player Lin Mu, the sacrifice was successful, and he obtained a [Blessing Power]!"

"Do you want to use this [Blessed Power] to forge weapons?"

Lin Mu did not hesitate, and read in his heart: "Yes!" ”

"Please select the weapon type!"

"Choose a gun!"

After Lin Mu finished choosing, the materials wrapped in light slowly gathered together, and after a while, a larger light cluster was formed.

The light of the large light cluster slowly disappeared as time passed, and slowly a 190-centimeter-long spear appeared in front of him.

"Ding!"

"——The system prompts, congratulations to the player Lin Mu, who succeeded in casting a divine weapon with the power of blessing."

"——The system prompts, player Lin Mu, you get the [Power of Wish Blessing] information: Sacrifice high-level rare items, you can obtain the power of Wish Blessing and fulfill a corresponding wish."

(The second more, ask for tickets, ask for rewards, and ask for all kinds of requests!!) ）
