The craziest upgrade system

Nie Feng was sent to clean the alchemy furnace, while Hei Yan curled up next to the bonfire and began to rest with his eyes closed.

Nie Yunze started meditating on the spot, and he was not idle now. He had to seize all the time to arm himself so that he could confidently deal with all situations that occurred in the competition.

Take out the poison sac that was just peeled off the blue-eyed poison frog from the inner space. In addition, there are also a large number of materials purchased at the auction, which contain a large amount of poison!

He took out the mortar and carefully put the poisons he had prepared into it.

The poisonous sac of the green-eyed poison frog, the heartbroken grass, the bloodless fruit, the rotten sunflower seeds, and the snake leaves. . . . . .

As one poison after another was put into the mortar, the pestle in his hand began to work harder and harder.

Time passed slowly, and by the time Nie Yun finished all this, it was already late at night.

Nie Feng had already washed the furnace and was meditating with his eyes closed not far from Nie Yun.

"Okay, now all the auxiliary medicines are ready, all that's left is the last main medicine." Thinking of this, Nie Yun thought and looked at Hei Yan beside the bonfire, who was happily sticking out his tongue to warm himself up.

After feeling Nie Yun's gaze, he suddenly opened his huge snake eyes.

Yes, Black Flame is poisonous, but its toxicity is inflammation poison, which is generally difficult to detect when the body is in a high temperature state.

A few minutes later, the clay pot the size of a water cup was filled with inflammatory venom.

View information.

"Level [-] Black Flame Snake Venom": The poison is inflammatory venom. The poisoned person will have fever all over the body, their movement will become sluggish, and their consciousness will be blurred.

Note: The venom must be in direct contact with the target's flesh and blood to have an effect. Otherwise, even if it is drunk directly into the abdomen, it will not have an effect!

Then Nie Yun didn't pay attention to Hei Yan's resentful eyes and started minding his own business again.

Add this last poison into the prepared Shiquan Tonic. After a while, the whole mortar showed a strange green pattern, and at the same time, the air began to be filled with a foul and pungent smell.

Then Nie Feng took out a clay pot the size of a water jar from the space inside his body, poured the Shiquan Da Tonic in the mortar into the water jar, and then placed the arrows in the space inside his body with the tip down, and put them vertically into the pottery jar. In the jar, until the tip of the arrow is completely submerged in the Shiquan Great Tonic.

He stood up and came to the alchemy furnace. Without avoiding Nie Feng, he selected some fine iron suitable for refining arrows from the space in his body, which even included a small part of iron mother.

Stuffing the metal materials into the alchemy furnace, he didn't stop until most of the alchemy furnace was filled. He placed his palms against the wall of the alchemy furnace and muttered silently in his heart.

Alchemy!

At the same time, spiritual power surged throughout his body and began to rush crazily into the alchemy furnace through his hands.

In the alchemy furnace, the spiritual power turned into fire and the temperature soared.

The fire of spiritual power quickly covered Jingtie's entire body.

The fine iron and iron mother began to slowly melt under the high temperature of the spiritual fire, and within a few minutes, they turned into a black liquid the size of a washbasin.

As the spiritual power output continued to increase, the temperature inside the furnace also continued to increase.A large amount of gray-black impurities are extracted, accompanied by a large amount of pungent green smoke.

Half an hour later, as the last trace of impurities was removed from the liquid, it was also announced that the first step of refining the arrow was officially completed.

At this time, the metal solution is only one third of the original size.

Then striking the iron while it was hot, Nie Yun stuffed more than half of the refined iron and iron mother into the alchemy furnace.Begin to continue refining impurities.

As time went by, the volume of the metallic liquid began to gradually increase. It was not until it occupied most of the space of the alchemy furnace that Nie Yun could no longer stop and slowed down the output of spiritual power.

Without much time to waste, Nie Yun used a free hand to take out a handful of Qi-Building Pills from the space inside his body. He stuffed it into his mouth like eating jelly beans and began to replenish his own lost spiritual energy.

Moreover, during the training process, the interval cannot be too long. Otherwise, if the temperature in the furnace drops, the metal liquid will solidify and form, and all the previous efforts will be in vain.

When the spiritual energy in the Dantian was almost restored, Nie Yun began to increase the output of spiritual power, and the temperature in the alchemy furnace rose again.

Another hour passed.

The metallic liquid mixed with iron mother in the alchemy furnace was gradually separated into a small ball by Nie Yun.

Under the control of Nie Yun's weapon refining skills, this small ball of metallic liquid slowly changed its shape, gradually condensing from a ball of oval liquid into the shape of an arrow.

Senhan's sharp edge spread out from the tip of the arrow, as if it could even cut through the air.

Wait until the arrow is completely solidified.

【Ding!Successfully refining the weapon, proficiency +1]

"Fine Iron Arrow": "Middle-grade yellow grade, made of a mixture of fine iron and iron mother. It is very sharp and can cause fatal damage to targets below the level of a martial artist."

"Very good, continue." After reading the message, Nie Yun became even more motivated.

After the refiner has completed the most difficult task of extracting impurities and fusing materials, the rest is actually very simple.

For the next two hours, Nie Yun spent all his time condensing arrows.

When the sky got slightly brighter and the early morning glow dyed the horizon red, Nie Yun finally completed the goal of forging arrows.

The long period of mental consumption has made Nie Yun a little exhausted. In addition to consuming a lot of spiritual energy, refining weapons also consumes a lot of mental energy.

But if Nie Yun had high-level flames, he could reduce the consumption of spiritual power to a great extent.

After putting all the items such as the alchemy furnace and arrows into the body space, making sure that nothing was left out, he found a relatively flat ground near the bonfire and fell asleep.

When Nie Yun woke up again, it was already three o'clock in the morning.

Black Flame has long since disappeared, and Nie Feng is practicing his sword on the side. However, the sword moves are very simple, and they are all the most basic. Picking, splitting, and stabbing are really nothing to see.

The bonfire was still burning nearby, looking at the prosperous bonfire and piles of new firewood that had been chopped and ready to be put in at any time.

Nie Yun smiled.

Come to think of it, there weren't too many words between the two brothers, and they each did their own thing.

He practiced sword.

Nie Yun began to count the results of last night.

Count the number of arrows carefully, and then subtract the 83 arrows you got at the beginning.

Nie Yun refined a total of 52 arrows last night.

After counting, he sighed inadvertently: "I originally thought that I could refine at least a hundred arrows, but the materials used now contain too many impurities, and the quality of the refinement cannot be improved if they are mixed with impurities." .

If impurities are removed and refined, the quantity will not increase.

I want to refine it again, but my spiritual energy consumption cannot keep up. . . . . "
