Furnaces, sheep's head ornaments, black animal skin carpets, barrels with aged wines.

This is the unique room that the Blacksmith of Hell has built under the lonely tower, unintrusive and free...... Moreover, the [Hell Blacksmith] is also extremely strong, and he can easily cross the Dead Lake and wander around the various districts of the Scorched Hell.

After reading the letter of introduction brought by Lu Ran, he didn't ask Lu Ran any questions about his identity or the origin of the letter of introduction, and went straight to the topic:

"Is the processing fee enough?"

Lu Ran hurriedly handed over the cloth bag containing a hundred ancient gold coins.

"Show me your materials."

"Good!"

Lu Ran also took out all the materials he bought, including the "low-grade fire crystal" that he had exploded by fighting monsters.

"It's all low-end materials...... However, it is not enough to collect so much material on this barren and desolate first level. Tell me what kind of weapon you want to build. ”

Lu Ran hurriedly took out his "titanium alloy chainsaw".

"Can this type of weapon be crafted?"

Ross easily grabbed the chainsaw with one hand, and the analysis was completed in less than a few seconds: "Is this kind of saw-like weapon that operates on its own through energy supply?" The processing fee for 'semi-automated weapons' is more than that. ”

"How much?"

"Double."

"This ......" Lu Ran still has 20 ancient gold coins left on his body, which is completely insufficient.

"I've got it here."

Xiao Yuan suddenly came up and took out all the belongings she had earned from running the inn from her pocket, totaling one hundred and ten ancient gold coins.

The blacksmith had just grabbed a hundred.

"Hmm...... The processing fee is enough! Tell us what you think, or I'll forge it according to my own philosophy according to the proportions of these materials. ”

"My main attribute of my spine is related to blood, can I build a chainsaw that is mainly based on 'blood'?"

"Blood? You're a bit demanding...... Let me think about it for a moment. ”

The blacksmith examined the materials.

"I had a particular idea, but there is no guarantee of a 100% success rate...... If you fail, you may lose all your materials! I'll only refund you half of the processing fee. If you can succeed, I believe you will be very useful. ”

"What is the success rate?"

"Because of material limitations, it's only about 60 percent...... You can refuse! I will refund all the processing fees and send you out of the [Lonely Tower]. ”

"Please!"

Lu Ran only has one chance, if he leaves like this, he doesn't know what to do with these materials, and the "Hell Pass" that he has earned through hard work to complete difficult tasks will also be wasted.

"Master Rose, what's your idea?"

"Make a semi-living and semi-automated weapon."

"Half-living, semi-automatic talking weapons?" When Lu Ran heard this, the 'dog stick' in a certain game immediately appeared in his head.

"Hmm...... It is expected to take two days, during which you and your minions will be able to rest in various areas of the Tower...... Don't let the souls of the dead in the Dead Lake take you away. ”

"Alright, thank you, Master Rose."

From Lu Ran's mind, a lot of finished saws appeared, and his heart was full of expectations.

If it does, this trip to hell will end perfectly! Dealing with the "photographer" will be smoother.

Rose blacksmith threw the material "Centipede Spine" to Lu Ran.

"Young man, you can't waste this spine! During my forging period, you can throw it into the furnace and collect the melted concentrate and drink it directly, which will help your spine a lot. ”

"Thank you, Master."

It was during the initial chainsaw sketch design at Ross Blacksmith.

Since he had said in advance that he would divide it equally with Huang Ying, Lu Ran divided the "centipede spine" into two sections.

According to the blacksmith, the "centipede spine" is thrown directly into the furnace, and the concentrated solution is collected from the iron cup where the beer is sipped......

"Serve it hot...... It's all serum, and it evaporates very quickly. Ross reminded.

"...... while it's hot"

Lu Ran stared at the freshly melted spine broth, the temperature was hundreds of thousands of degrees Celsius...... According to common sense, drinking it can really kill people.

With a worried mentality, Lu Ran tried to dip a drop with his tongue.

Although the tip of the tongue is burned, the fluid from the spinal bone in the swallowed mouth does not go down the esophagus, but directly into the bone marrow...... There was a strong burning sensation coming from the back and a feeling of a sauna.

Lu Ran hurriedly drank the remaining concentrate in one gulp, white and viscous, hot and hot.

Suddenly, Lu Ran was sweating like rain, his whole body was red, and there was constant steam overflowing.

"The spine is growing...... It's the same feeling as when I was in No. 9 Middle School. ”

While the fever was hot, Lu Ran could clearly feel that the upper part of his back was gradually strengthening, and his ribs were also changing.

Lu Ran hurriedly stretched out his arms to adapt to this process of change.

The muscles of the whole body can be seen to rise and fall in the process, and a steady stream of power essence is overflowing from the upper back bone, slowly flowing to the left and right arms.

Half an hour passed, and after the heat subsided, Lu Ran hurriedly took out his mobile phone.

『The spinal system has been upgraded, the third stage - [chest shape]』

[Thoracic type]: The thoracic region of the spine, a total of 12 vertebrae have been activated. The strength of the upper limbs has been increased, the rib armor protection has been improved, and the "heart" layer has been established.

"Such a big increase!?"

Lu Ran is currently aware of the three stages of the improvement of the "spinal system".

The first stage [tail detachment], which is the initial stage when the system is opened, can improve the strength of the lower limbs, so that Lu Ran's running ability is improved, and he can kick the puppet that is pressed on his body and easily jump from the second floor of the teaching building.

The second stage [Waist Emperor], this stage makes the center of gravity of the body solid, and once Lu Ran stands firm, it is extremely difficult to shake...... In the face of Senior Sister Luo (centipede form), who has the joint force of five people, she can still barely fight head-on for a while. Moreover, it can greatly improve Lu Ran's 'rock climbing' ability, and there is no big problem in climbing up and down the building wall.

The current third stage [chest type] has increased more than Lu Ran imagined, and the increase in arm strength means that Lu Ran has strong aggression, and can even swing the "titanium alloy chainsaw" with one arm.

It is especially important that the ribs form a layer of defense that protects the heart.

Just when Lu Ran's growth was completed, he directly started doing one-arm push-ups on the spot, and there were thirty of them.

"It's so strong! I didn't expect such a gain. ”

Originally, with the idea of forging "Hell Weapons", the first thing was to accidentally gain the forbidden demon formation given by the [Hell Monk], and now it has actually upgraded the spine system to the third stage, and the comprehensive combat effectiveness has been greatly improved.

"The last stage of spine development should be the cervical spine, right? …… When the "spinal system" is perfected, there should be another level. The spine is like the foundation of the human body, and it's really exciting to compare it to the "foundation building period" in fantasy novels!! ”

Thinking that his body could really be "upgraded" like in the game, Lu Ran, as a fan of the game, was excited.

In the next forging time, Lu Ran will live with Xiao Yuan in the [Lonely Tower] for two days and two nights.
