"I'll wipe it, I'll wipe your uncle!"

The roar of resentment echoed in the basement, and the resentment may not have been appropriate, but he must have wanted to cry without tears.

Half a month ago, after handing over the good exercises to the seven of them, Lu Li locked himself in the basement, half a month, he didn't want to waste half a month, it was good that his strength could be improved even a little.

However, he was not in a hurry to cultivate the Chaos Ascending Yuan Technique now.

First, after the Chaos Dengyuan Jue was promoted to the martial artist realm, the resources consumed by each layer of improvement were too exaggerated than before, if the martial apprentice realm was only ten times, the martial artist realm would be at least fifty times higher, and this kind of consumption was a little unbearable even for Lu Li.

The spirit stone on his body is only more than 10,000 points now, if he really wants to use it, improving his strength is simply a drop in the bucket, and it is not as good as using this 10,000 spirit stone in other places to get a big benefit.

The second reason is that even if he raises the Chaos Ascending Yuan Jue now, his mecha has already limited the strength realm that he can exert now, and the foundation of the mecha itself is not strong enough, which has become his current shortcoming.

Taking into account all aspects of the situation, coupled with the star stone obtained from the auction, Lu Li decided to spend half a month to upgrade his mecha in an all-round way.

The Star Stone itself can be called one of the excellent materials for making mecha because of its high density and high strength, and if you want to smelt it by conventional means, with the level of mechanization in this basement, Lu Li has no way at all.

Unless he spends at least ten days or more building a melting pot and a precision lathe for himself, the Star Stone will always be a Star Stone, and it will never be a powerful bone to support his mecha movement.

In ten days, Lu Li felt pain when he thought about it.

Even if the night god records all the industrial systems in the Earth Alliance, but after all, he has only one person, and one person completes the manufacture of an entire industrial system, so there must be countless factories and extremely huge places, even if the entire Linyuan City is set up, it may not be enough.

Troublesome, just troublesome to the extreme.

In contrast, the refiners of this world are much more convenient, they don't need to think about what factory or system at all, they only need a special refining furnace, with the help of a powerful furnace fire and magical technique seal, any material can be refined into what they want.

If you use the refining method to refine the mecha bones you need, wouldn't it be much more convenient?

As soon as this thought appeared, Lu Li could no longer erase it from his mind.

Anyway, sooner or later, I have to learn how to refine weapons, so it's better to start now.

Thinking like this, Lu Li focused his attention on refining weapons.

He didn't lack the ordinary materials needed for refining, and he also had three refining furnaces, all of which were provided to him by the bigwigs in Linyuan City before, and now they were just being used.

Refining is a delicate job, if there is no night god, with Lu Li's half-trick level, let alone becoming a refiner, even if he is asked to control the refining furnace, I am afraid he will not be able to do it.

The reason why those bigwigs in Linyuan City would take out all the materials they have treasured for so many years is actually because of this reason.

If you don't have talent, you can't achieve anything if you let him refine the weapon for a lifetime, at most, he will refine and waste the materials for a lifetime, and in the end he will get nothing.

Even if you have talent, it will take countless accumulations and practices to be able to master the characteristics of each material and grasp the temperature of every point of flame.

Lu Li is different, because he has the Night God, the Night God's records and incomparably detailed observation ability can allow him to carry out extremely precise control at a level that others can't perceive, with such a unique ability, if he can't become a refiner, then it is better to simply find a piece of tofu and crash to death.

"Why don't you practice first, Night God, let me casually follow the refining process of the weapon, let's see how wonderful this refiner is first. ”

"Okay, Lu Li, the data search is complete, the data comparison system is ready, the refining process of the refined iron sword and the raw materials required are as follows......"

The voice of the night god continued, and Lu Li's hand did not stop.

It was just some very ordinary material, and as soon as he grabbed it, a handful appeared.

"Make a fire!" Lu Li pinched his hands, and the power in his body quickly entered the refining furnace, and the flames in the furnace jumped, and soon the temperature was raised.

"The temperature exceeded the critical value by fifty degrees. ”

"The temperature is right, and after three seconds, we are ready to put in the fine iron. ”

"The impurity content exceeds the standard, and the current content is 30%, and refining continues. ”

"The temperature is too high, and the properties of fine iron are destroyed, so please try again. ”

......

The voice of the night god reminded Lu Li again and again in his mind, and Lu Li could be regarded as having experienced what it meant to collapse.

Even if there is a night god with him, he doesn't know how much refined iron he wasted in order to refine an ordinary refined iron sword, the basement is full of slag that he has refined, three days later, the first refined iron sword finally condensed successfully, Lu Li looked at the refined iron sword in his hand that had reached the perfect level, he rubbed his eyes that were already red, grinned, fell to the ground with a bang, and fell into a deep sleep.

After a whole day and a night, he woke up from his sleep, and when he recovered his spirits, he first went to refine a fine iron sword to suppress the shock.

The effect was really good, and it was a perfect finished product, Lu Li was very satisfied, so he began to challenge the second difficulty.

In this cycle, he didn't know how many things he had refined, anyway, after consuming all the primary materials on his body, Lu Li gave up.

He knew that he had reached the most critical time, because what he was going to refine now was nothing else, but only a point star stone.

This star stone worth 45,000 spirit stones carries his hope, in this battle, he can only succeed, and he must not fail!

Ignition, furnace heating, feeding, purification, every step of the land has achieved the perfect realm, he looked at the pool of sparkling stars in the furnace, like the Milky Way without the slightest impurity of the solution, he smiled with satisfaction.

"Okay! The Star Stone has been refined to perfection, now all that remains is to shape, Night God, do your best to assist me, and let our mecha embark on the road to the top of the king again!"

Lu Li is full of confidence and pride.

It was only a moment later that he could no longer be arrogant.

"What did you say?" Listening to the voice of the night god, Lu Li was stunned for a moment.

"Host, you heard it right, because the ability to refine the refining method is too strong, coupled with the host's full effort, the point star stone that has reached an almost pure state is only enough to equip a mecha arm according to calculations, please judge for yourself. ”

"Damn, there is still this kind of operation?" Lu Li was dumbfounded, he actually purified a material that could equip the entire mecha to the point that it could only equip one arm, how could it be embarrassing!
