There was a loud roar in the darkness, Chu Weiwei was awakened from her sleep, she was a little dazed for a while, and she couldn't figure out where she was?

Infrasonic bombs, scaly beasts, Xiang Hong, passion in the dark...... Before Chu Weiwei could fully come to her senses, broken stones began to fall from above, and then a ray of light shot into this enclosed underground space. Pen ~ fun ~ pavilion www.biquge.info

Instructor Li's voice sounded from the light source: "How are you two doing, are you okay?" ”

Saved! An excited smile appeared on Chu Weiwei's face, but then her face changed, and she exclaimed and stretched out her hand to cover the spring light on her chest: "You guys wait a minute, give us some time!" ”

Then she stretched out her slender jade legs and kicked Xiang Hong, who was still asleep on the side: "Get up!" Still sleeping......"

When the sleepy-eyed Xiang Hong and the embarrassed Chu Weiwei came out of the ground, the two found that their location was already on the plain on the left side of the mountain. The towering mountain had now collapsed in half, and huge rubble was rolling down the plain.

"It's good that you two are fast enough, and if you slow down, you will be crushed by the whole mountain." Instructor Li looked at Xiang Hong and Chu Weiwei with a smile on his face. Both of these men are very important to the base, and if something goes wrong here, he can't explain it to the patriarch.

Xiang Hong rubbed his eyes and asked, "Those scaly beasts are all killed?" ”

Instructor Li laughed twice and said, "There is no life reaction in the entire mountain, and even if there are one or two fish that slip through the net, it will not pose any threat to us." ”

Then he looked at the collapsed mountain peak in front of him, frowned, and said, "But the mine has collapsed like this, and the mining plan must be reformulated." ”

Xiang Hong nodded: "The rest of the matter will be hard for you, I will take Weiwei back to the patriarch first." ”

After explaining to Instructor Li, Xiang Hong and Chu Weiwei found a floating car and returned to the base along the transportation road. The two of them were silent in the car, and Chu Weiwei naturally leaned into Xiang Hong's arms, squinting her eyes and enjoying the oncoming breeze.

The atmosphere was particularly warm and beautiful, and in silence, Xiang Hong touched his nose and said, "Oh no, it seems that I forgot eight thousand in the pit......

Turn back and retrieve XL8000 from the bottom of the pit, after which the two return to the base and report directly to the patriarch about the mission.

After all the reports, Xiang Hong added: "Patriarch, now that the combat range of the base is getting bigger and bigger, we must consider the problem of communication, and without timely intelligence interaction, it will be very unfavorable to the battle on the front line." ”

The patriarch nodded: "I took this into account when setting up an outpost in the mine, but I haven't found a suitable technical solution in the mastermind yet. You two have worked hard and made great contributions this time, so let's take a day off today. ”

In the year-long time and space shuttle mission, this is Xiang Hong's first holiday, and after a short day of lingering, Xiang Hong and Chu Weiwei once again ushered in the moment of separation.

Early the next morning, with a large number of precision instruments, Xiang Hong returned to his cave in the Shengxian Era. XL8000 floats in the air with a red glow, exceptionally silent, as if it is still resentful of being forgotten in the cave yesterday.

Xiang Hong filled the floor with a large number of equipment such as micro vacuum distillers, molecular grinders, and multi-layer molecular filters, and then looked at XL8000 and said, "Old man, let's get to work." ”

XL8000 flew in the air and made a sound: "Now transfer the purification methods of various medicinal materials and the improved Yunyuan Dan formula to you for the first alchemy experiment." ”

Although Yun Yuan Dan is the most elementary elixir, as a elixir that can increase cultivation, the complexity of the formula is far beyond the ordinary, and a total of seventeen kinds of spiritual materials need to be used, some of which need to be ground, some need to be roasted, and some need to be soaked in water to extract juice.

In terms of the production process, alchemy is indeed very similar to chemical experiments, using various methods to extract the required substances from a large number of spiritual materials, mixing them to make a blank, and then putting them into a Dan furnace to refine, and finally becoming a pill.

With the help of a room full of precision instruments, Xiang Hong's purification efficiency far surpassed that of ordinary alchemists.

It would take at least a month for an ordinary alchemist to extract the full set of raw materials needed for Yun Yuan Dan, but Xiang Hong completed this step in less than three days. The large number of spiritual grass and spiritual materials piled up in the corners of the house had already been processed by him, either liquid or solid, and they were respectively put into a large row of flasks.

The next step is to mix these materials to make a blank. In the process of manufacturing blanks, the ratio of materials is extremely important, and the quality of a pill mainly depends on whether the proportion of various medicinal materials in it is accurate.

For ordinary alchemists, it is difficult to extract high-purity raw materials, and there is also a lack of precision measuring tools when mixing the blanks, so the quality of the refined pills is uneven, and if you want to refine the best, you can only rely on luck.

But for Xiang Hong, who has a multi-layer molecular filter and a precision static scale, these two points are not a problem at all, and he quickly prepared the first blank according to the formula provided by XL8000 according to the extremely precise ratio.

Finally arrived at the step of alchemy, Xiang Hong couldn't help but be a little excited, he put the dim bronze pill furnace on the molecular vibration heating pad, and set the heating temperature at three thousand and six degrees according to the instructions of XL8000. Then he opened the Dan furnace and solemnly put the black medicine blank into it.

With a constant temperature heat source and an ancient bronze pill furnace, Xiang Hong nodded slightly, and said in a low voice: "It seems that alchemy is not as difficult as it ...... said."

"Bang ——!"

With a loud bang, the top of the Dan furnace rose to the sky, and then a large cloud of black smoke poured out from the bronze Dan furnace, smoking Xiang Hong's face with black ash, and the alchemy room was suddenly filled with black smoke and miasma.

"Boom ——!"

The top cover of the Dan furnace fell to the ground, constantly rolling back and forth, making a series of metal crashing sounds, Xiang Hong looked at XL8000 inexplicably: "What's going on, how could it fail?" ”

XL8000 spun around in the air and said slowly: "The first alchemy failed, and the reason for the failure is inferred to be: the estimation of the density of spiritual power in the atmosphere is wrong, and the proportion of various raw materials needs to be adjusted. ”

Xiang Hong frowned and said, "Why didn't you even think of such a basic question, it wouldn't be intentional!" ”

XL8000 flashed red, and his voice calmly sounded: "I am a loyal assistant to assist you in your cultivation, and I will never deliberately change the formula of the elixir to retaliate because I was forgotten deep underground." ”

"Holy!" Xiang Hong stretched out his hand and wiped the black ash on his face, but instead wiped himself into a flower face: "Sure enough, it's deliberate, next time there is a problem, I will smear you with medicinal herbs and put it in the Dan furnace!" ”

XL8000 hovered in the air: "Understood, now the revised herb recipe data will be transmitted to you." ”

After receiving the new formula formula, Xiang Hong began to remake the blank again, this time the blank was very stable after being put into the Dan furnace, and there was no fryer.

Three hours later, a strong spicy medicinal fragrance wafted out from the bronze pill furnace, Xiang Hong lifted the top lid of the pill furnace, and carefully took out the first pill he had refined from the pill furnace.

The red and full Yun Yuan Dan was in the tray, flashing with a bright luster, which looked quite spiritual.

"The accuracy of the ratio of various spiritual materials of this Yunyuan Pill is extremely high, and the effect of the pill is expected to be more than three times that of the ordinary Yunyuan Pill." The voice of the XL8000 rang out on the sidelines.

Xiang Hong looked at the red Yunyuan Dan and couldn't help but smile, from now on, he was a supreme alchemist in the Shengxian Era.
