Zhang Guangmu, who had made sufficient mental preparations in advance, felt a sharp pain explode in his back almost the moment the plan began to be executed.

Yes, Zhang Guangmu thinks that the word "explosion" is very accurate to describe the pain on his body at this moment.

He felt like someone had stuffed a ton of explosives into his spine and detonated it without hesitation.

In an instant, the cervical, thoracic, lumbar, and caudal vertebrae seemed to be broken into countless sections, giving Zhang Guangmu the feeling that he had scooped up a scoop of hot oil and poured it directly on his crest, and then sprinkled a handful of chili noodles and pepper salt on it.

The above description is not an exaggeration.

With Zhang Guangmu's self-control ability and ability to endure pain, he still almost rolled his eyes at the moment when the severe pain hit, the blue tendons on his forehead and neck bloomed, and his handsome face also showed a bit of hideousness at this moment.

The pounding heart pumped out a large amount of blood, and instantly supported the capillaries, making Zhang Guangmu's whole person look like a ripe crab, red.

Zhang Guangmu can barely endure such pain.

After all, it was self-inflicted, and he had already had psychological expectations, relying on his rich experience of enduring hardships and pains, Zhang Guangmu finally passed this wave of painful tests.

However......

The most difficult part of casting the [Sword Bone] lies in how Zhang Guangmu endured the pain while maintaining his sanity, and used the most delicate techniques to forge his crest pillar into a "sword" while maintaining its activity and normal function.

It must be admitted that this is a very difficult job.

In order to ensure accuracy, Zhang Guangmu could not use anesthetics, nor could he block some pain nerves—he had to get first-hand experimental data through feedback from his body.

Pain is also a kind of intelligence.

But......

The severe pain almost made Zhang Guangmu's consciousness foggy, and he couldn't wait to fall asleep immediately.

Fortunately, after the [Imperial Body Forging Technique 23], Zhang Guangmu, who had reached the stage of [Yang Casting God], had a stronger spiritual will than before, and he persevered.

Zizizi......

The sound of fried pork ribs kept ringing in his ears, and between his noses, there was also a strong aroma of cumin barbecue, Zhang Guangmu knew that this was an illusion caused by the nerves being stimulated by the power of Jian Yuan.

He has no distractions and is focused.

Minutes ticked by.

One minute......

Five minutes......

Ten minutes......

In this state of seconds, Zhang Guangmu, who had persisted for a full twenty-three minutes, finally breathed a sigh of relief.

At this time, the sweat dripping up and down his body had completely soaked his clothes and futons, and the water in his body had evaporated a lot, and the whole person was in a state of serious dehydration.

If it weren't for the sword yuan power provided by the Mirage Sword and the Sword Net to help maintain the operation of the major organs of the body, Zhang Guangmu suspected that he would immediately pass out and then die in a coma.

Hurriedly drank a few glasses of water, and after quenching his thirst a little, Zhang Guangmu took two bottles of glucose saline from the medical box and poured them directly into his stomach as a functional drink, and his physical state gradually began to recover.

"It worked."

Zhang Guangmu's eyes closed slightly, and he carefully felt the changes in the spine pillar - several physiological bends of the spine have maintained their original state, and even the functions that belong to normal humans have been perfectly retained.

At this time, the light that came from nowhere fell on the skin on Zhang Guangmu's back, shining as white as jade on the ridge, and through the muscle skin, it also emitted a glowing glow.

Zhang Guangmu suddenly had a kind of realization - his crest pillar was regarded by heaven and earth as a [not sharp bone curved sword], an unorthodox spirit sword similar to the Golden Snake Sword and Wu Hook.

"Let's just call it ...... [Mad Monarch Bone]."

In addition to the identity of [Swordsman], he also has an additional sub-class called [Sword Forger].

As the forger of the [Mad Monarch Bone Sword], Zhang Guangmu's mind seemed to have another self starting to speak.

[This spirit sword hidden deep in the spine pillar is my first work, and it is also a masterpiece whose excellence is not under the mirage sword!] 】

[It can grant the swordsman two abilities.] 】

[The first is to summon a hard dense bone shield at any time to resist attacks.] 】

[The second is a passive ability, those who hold this sword can obtain several times the self-healing ability of ordinary people's bodies. 】

[Perhaps, I have a strong talent for swordsmiths......]

Obviously, the two major functions of the [Mad Monarch Bone Sword] are taken from the "hardness" of the bone and the "hematopoietic function" of the bone marrow, which is logical and quite scientific.

It's just that......

Like the vast majority of swordsmiths, Zhang Guangmu also knew what it was and didn't know why.

Why can the forged spirit sword have extraordinary power as vast as the stars?

I don't understand!

At this time, the vicissitudes of life and wanton young narration suddenly sounded.

Zhang Guangmu suddenly had a strange feeling - the sword is the spirit of all things in this world, and human beings are just an intelligent race that serves the sword.

"At this moment, this mad monarch naturally understood two truths."

"First, if you want to forge spirit swords with different attributes, you only need to invest in the corresponding category of materials."

"(2) The greater the reputation as a swordsmith, the higher the grade of materials used in sword casting, and the higher the level of spirit sword can be smelted!"

"As for the forging technique?"

"Those can only be used as icing on the cake, in this world, and it doesn't matter."

Zhang Guangmu didn't know what to say.

He even had some doubts that as a rookie swordsmith, he could refine a spirit sword like the [Mad Monarch Bone Sword] that was not inferior to the [Mirage Sword], purely because his record was strong enough and his reputation was big enough, and he was widely recognized by people.

Good-looking romance

Theoretically, such a reputation is limited to the status of [Swordsman] and does not help [Sword Forger], but Zhang Guangmu was relieved when he thought about it.

The material used to forge the sword this time is the spine bone on the body of the [Fourth Sword Emperor Mad Monarch]—how many sword smelting materials in the world are more advanced than this?

I'm afraid I can't find a few!

Anyway, at this point, "Dream Demon Project" has come to a perfect end!

Zhang Guangmu was a little glad that he didn't hold it up, he held his hand steady, and his preparations were relatively sufficient.

The process of "smelting sword bones and making swords with example" can be regarded as thrilling and dangerous.

The changes in Zhang Guangmu's body fed back to the Dream Demon Sword Gu hidden in the air, making him feel like a tiger with wings.

With just a few breaths, the Dream Demon Sword Gu completely devoured the remaining part of the [Wind Domain Sword].

After absorbing all the essence of [Wind Domain Sword], the sword network was updated and officially upgraded to version 2.0.

From now on, Zhang Guangmu will be able to control the sword force of water and wind at the same time.

The combination of water and wind sword yuan power has a lot of benefits, and now it is ......

The first advantage Zhang Guangmu felt was that he could directly drain the sweat-soaked clothes, and he could also make them crisp and new without wrinkles.

Refining the sword bone is essentially "internalizing extraordinary power".

This matter may not mean much to others, but to Zhang Guangmu, it is very important.

Because it represents that Zhang Guangmu in this world is no longer an ordinary person who purely relies on external forces, but an extraordinary person who is truly recognized by Brother Shu!

Zhang Guangmu stretched out his hand, and the wind and clouds converged, gathering a blue-blue book in his palm.

In the profile, in the achievements column, there is a piece of data that has not been touched for a long time, which has quietly changed.

Is that......
