Taibai Volcano, to be precise, should be said to be the Taibai Volcanic Group, in addition to the large crater where the Tianchi of Taibai Mountain is located in the past, there are more than 100 small volcanoes dotted around, becoming a continuous snow hot spring volcanic area.

The Taibai Fortress was built on the main road leading to the large crater, and there is a hidden straight in the belly of the mountain that leads to the perimeter of the lava pool.

"Good guy, the spiritual power is going to be substantiated."

Su Tian only got closer, and he felt that there was an almost endless amount of heat coming from the crater—listening closely, he could hear the sound of the power of the fire spirit leaping.

Fortunately, although this volcano is active, it is still very early to erupt, at least with Su Sun's superhuman spiritual power affinity and perception, it can be determined that this Taibai volcano group will not erupt in the next few decades, and now this situation is at most dangerous but not dangerous.

"But no matter what, dare to run to the crater to forge a divine weapon, this courage is really good."

Although Su Yan commented so, he couldn't help but be taken aback when he was really introduced by Zhou Buyi to the forging base in the belly of the volcanic mountain.

Because what appeared in front of him was not the simple workbench he imagined at all, but a complete set of incomparably sophisticated steam casting centers!

- Phew!!

It can be seen that under the golden red light of the lava lake not far away, with the control of the busy craftsmen, the huge stainless steel machinery is running with the screaming steam, which is continuously draining the molten iron and converging in the large pool in the center, and the almost boiling fire spiritual power is almost condensed into a visible form here, and the light like the red gauze is like an aurora, floating above this large pool of molten iron.

In the center of this pool of molten iron is a piece of tungsten gold gold that is placed on a high platform engraved with a pattern, dazzling, like molten iron is a golden-red crystalline metal, which is constantly absorbing the high heat of the lava lake and the surrounding molten iron at this time, condensing the blazing energy of hardware and earth veins in its own body.

"It's already to the point of steam machinery? And this is the leyline inflammation iron? ”

Although Su Yan knew that the technology of this world might not be as ancient as he imagined when Mo Ganxiu took out the 'Vermilion Bird Box' to cauterize the demon soldiers, after all, purely according to time, the An Dynasty was about to enter modern times - but he really didn't expect that the painting style of this world turned out to be steampunk martial arts!

"Brother Su hasn't seen this 'True Qi Casting Furnace' before? That's right, you used to live on the Kunlun Mountains. Zhou Buyi saw Su Day's surprise, so he explained with a smile: "Although the Demon Emperor of the An Dynasty has no way, but in the era of Emperor Xuan of Emperor Xiao, the world is at its peak, and this 'True Qi Casting Furnace' was created by my Taoist predecessors and craftsmen in the past, and the original intention was to make a more efficient alchemy furnace, but it turned out that as long as it is driven by the crystallization of various spiritual objects, it can exert a power far superior to that of human beings!" ”

"It's just a pity that this true qi device that operates the Heaven and Earth Yuan Qi mixed with steam requires internal strength to be controlled and used by martial artists, and cannot be used by the people on a daily basis."

At this time, seeing the arrival of Su Yan and Zhou Buyi, a tall man covered in bronze and coiled muscles walked out of the core control of this True Qi Casting Furnace, the muscles of his wrists and shoulders bulged abnormally, the blue-purple blood vessels and meridians expanded and twisted, and hot blood flowed in them.

This person's internal strength cultivation is about the same as Zhou Buyi's, and he has broken through the second order of the day after tomorrow, but it can be seen that the strength of the two sides to sharpen their physical bodies is not the same.

After coming to the two of them, the tall man did not speak, but a voice formed by internal force concussion came from his abdomen: "Xiao Zhou? A new grandmaster? ”

"Great masters are naturally unable to speak, so it may be relatively brief to communicate in ventriloquism." Zhou Buyi explained to Su Day, and then introduced Su Sun's intention and intentions.

Su Tian also naturally took out his cross spear, as well as the Yin Aura Crystals that had been stored for a long time and had never been used.

"Recast, this gun? No, question. Oh, Psis! ”

At the beginning, when he saw the Wood Centipede Cross Spear, the expression of the great master craftsman was quite disapproving, it seemed that he had seen too much and was not interested, but after seeing the gloomy crystal, his eyes suddenly lit up: "Purity, extremely high!" Unfortunately, it didn't work out. ”

However, he saw that this obscure spiritual power crystallization could be advanced to the earth vein condensation core, and it had not yet become its final form.

"Really, you want to use it?"

The Grand Sect Craftsman raised his head, his eyes puzzled, and Su Sun naturally nodded: "Of course!" ”

Although the great master craftsman didn't make sense of what he said, as Party B, he didn't need to talk much, and after waiting for Party A's Su Sun to clarify his needs, he only said, "Okay." And "Today, busy, tomorrow, come again." Then he turned his head and continued to control the True Qi equipment.

Returning to the fortress camp, the rebels originally planned to arrange a place for Su Sun, but after Su Sun looked at the wooden house that was too simple and even leaky, he shook his head, opened his backpack, and set up a tent next to it.

He tried to trade some local specialties with the gems, spices and other modern things he brought over, but the result was quite gratifying, and he got a lot of Taibai Mountain specialties, five old ginseng soaked in aura.

"Although these mountain ginseng has not yet become a spiritual plant, it does contain a lot of spiritual energy, put it on the earth, it is also a half-day genius treasure, you can strengthen your body after eating, full of energy, five together, the spiritual energy can be compared to the real spiritual plant, I don't know how much it costs to buy."

"As a result, in this Shenmu world, although it is rare, it is not precious, looking at the appearance of those few martial artists, I actually feel that I have earned - each takes what he needs, and it is a win-win situation."

In his tent, Su Yan weighed the peculiar mountain ginseng in his hand that was white and pure, and was infiltrated with spiritual energy, which felt quite beautiful, but Yara prompted: "Actually, it's not just this reason. The existence of the Banyan Immortal Tree will affect the plants of the whole world, although this ginseng has aura, but the wood gas is too heavy, and there are too many impurities, if you eat too much, the speed of family conversion will become faster, and the locals will not dare to eat this thing if they are not in a critical moment. ”

"But you're different, you're my dependent, and you're not afraid of this bit of erosion and impurities—just right, try the 'refining and refining qi' I taught you."

Refining Qi, one of the three general skills taught by Yara, is different from the other two skills that can be used in battle, until now, Su Day, who was born with an amazing amount of food, has not encountered a time when he really needs to use it.

As for now, it's just right!

Sitting cross-legged in his tent, Su Tian closed his eyes and began to 'condense qi in his body', fine-tuning the aura structure in his body, condensing a large amount of spiritual power in digestive tract organs such as the stomach and intestines, and under the layers of small stimuli, he felt that there was a sudden hunger surging from the deepest part of his body!

Click!

Without hesitation, Su Tian directly copied a mountain ginseng next to him, and then took a bite - it was extremely bitter at first when he entered the mouth, but soon a sweet and sweet taste infiltrated the five senses, and a breath of pure spirit rushed straight to the brain from his eyes, ears and nose!

Click, click, continuous opening of the mouth, less than two seconds, a whole child's arm-sized mountain ginseng was swallowed by him like this!

Coaxing--And at the moment when the food containing spiritual energy entered the digestive organs, Su Sun felt that a spiritual power containing powerful wood qi exploded from his stomach, and then spread to the whole body along the spiritual power structure that he had fine-tuned before, just like soaking in a hot spring, a warm ocean, and the feeling of hot baking suddenly spread to the whole body, causing the temperature in the entire tent to rise.

"The body is being strengthened – from the tiniest part!"

Su Sun could feel that every cell and every muscle fiber in his body was hungry and thirsty, and after receiving the warmth of the aura, they also became stronger and more vigorous at a speed visible to the naked eye.

After running for several seconds, the aura dissipated, and although the amount of old ginseng's aura was not large, it was far inferior to the wood centipede crystals and the dusk true demon crystals, but it was superior to the large number.

Click, click! Su Sun directly gnawed two more, and then continued to calm down, using his own fire spirit power to directly smash the wood qi in this ginseng and convert it into an ordinary aura that he could use, even if there was a slight precipitation of wood qi, it was also worn out by Su Sun's own physique.

Yin and yang are reciprocal, the five elements rotate, the four elephants alternate, and the eight directions are shifted - this method of refining and refining qi, although the name is extremely simple, but in essence, it is the 'Heaven and Earth Eating Technique' that encompasses everything and can almost decompose, digest and devour all spiritual machines!

If an ordinary person directly swallows the elixir spirit plant, it is a fluke to get one or two of the ten layers of efficacy, and half of the effect is normal, and it is more likely to make up for oneself to death, or the medicine is too strong and goes crazy.

If you want to absorb it safely, you need to convert it into an elixir potion or a more gentle and efficient method of absorption, such as spiritual food.

However, refining and refining qi is different, although compared to the high-grade elixir potion, the effect of increasing the original ten-layer potency to twelve percent or even doubling it through various techniques and auxiliary materials is still inferior, but it can still be compared to the medium elixir, with a conversion rate of seven or eight percent.

In terms of absorption efficiency, compared with the various elixirs that still need to be refined for a long time, 'refining and refining qi' has an absolute advantage.

That is to say, Su Tian's strength is not high now, and the scope of refining and refining qi cannot cross ordinary spiritual objects and spiritual plants at present, if he waits for him to go further, I am afraid that not all spirit stones and spirit iron can be eaten.

"Good! The resources of the other world are really abundant, and the windfall of this resource alone is already so abundant! ”

After more than ten seconds, Su Sun opened his eyes, his eyes were bright and bright, the hunger in his body temporarily disappeared, but the spiritual power contained in him increased a lot, at least to the level of hundreds of resentful soul fragments!

The progress of this cultivation is already what he needs to spend more than ten days on Earth to advance and stabilize!
