The volcano had stopped spewing magma, and although the magma from the summit was still flowing out, it was no longer dangerous for the monks. The edge of the lava has begun to cool, but the surrounding fire is slowly spreading outward.

When the four of them flew back to the edge of the magma, they stopped and looked around. Wen Jingxin stretched out his right hand and sucked it into the magma, and a cloud of black gas appeared in the palm of his right hand. The four of them looked at it, only to see the black gas invading towards Wen Jingxin's palm, so Wen Jingxin immediately blew a breath into his right hand, and the black gas was instantly blown away.

Sun Yanfei put away his usual indecency, and said very seriously: "The black gas produced by this magma is quite toxic, and it can also penetrate through the skin, I'm afraid that with the ability of the four of us, we can't withstand this poison." ”

Ma Xingye was extremely incomprehensible, and said with a frown: "No matter how strong the toxicity is, what does it matter to us, just don't go in." Besides, I am afraid that such a great power of heaven and earth can be detected from tens of thousands of miles away, and it may have attracted Yan Haimen's attention. Let's go quickly!" Just after speaking, I saw the three senior brothers smile and shake their heads, which made themselves even more incomprehensible, and continued: "What's the matter, am I not right?"

Mu Xiaotian patted Ma Xingye on the shoulder and said, "Senior Brother Ma, you are good at commanding Dao soldiers and have the talent of a general, so I don't know much about this piece. Such a large volcano has been silent for thousands of years, and I don't know how many heaven and earth spiritual fires have been bred, in my sense, the magma mouth at the peak of the volcano is afraid that there is a spiritual fire with a Dao level. ”

After listening to Mu Xiaotian's words, Ma Xingye suddenly realized, but after thinking about it carefully, he found that he was a little lonely and unheard, and he was suddenly a little embarrassed.

"But what Senior Brother Ma said makes sense, the vision of heaven and earth is so big, and the volcano erupted for a full day, it is estimated that some monks have begun to rush here by now. But as far as I can guess, they won't be able to catch it in two days, so we're going to take advantage of this time to collect the spiritual fire. Of course, we must get the Dao Rank Spiritual Fire in Senior Brother Mu's mouth. Wen Jingxin was extremely confident, thought about it in his heart, and then said what he thought in his heart.

Mu Xiaotian looked at the black gas coming out of the magma, looked at Wen Jingxin and asked, "Senior Brother Wen, can this black gas be solved with pills." ”

Black gas is constantly emitting from the magma, causing the air in the area to turn black. Of course, as the magma cools, the black gas will gradually dissipate.

"The toxicity of this black gas is so strong, even if there is an elixir to restrain us, we can't refine it. I want to use the body protection qi to isolate the black qi. Of course, the Protective Gang Qi cannot be used for a long time in high temperatures, but we can harness the Alchemy Furnace to collect spiritual fire in the magma. Removing the lid of the furnace, one person harnesses and uses the Gang Qi to isolate the black gas, while the other collects the spiritual fire. ”

"Good idea. The three of them nodded, instantly realizing that the idea was good.

Every monk will use the Protective Gang Qi to release the true essence in the body, turning it into a Gang Mask and enveloping itself like a bubble. It can play a certain defensive role and isolate itself from the outside world. The Protective Body Qi strengthens as the cultivation increases. The Supreme Strongman's protective body Gang Qi almost turned into an entity, like a golden bell jar, and he could dive into the deep sea and magma directly with Gang Qi.

And Mu Xiaotian's four people cultivated to only the early stage of real people, and the Gang Qi was the weakest one, barely able to isolate these black qi. But the magma temperature is very high, at most it lasts for a period of time in the magma, but the magma covers nearly a thousand miles. With the qi of Mu Xiaotian's four people, they can walk on the edge for a generation at most. If you want to go deep into the volcano, Zhenyuan will definitely not be able to hold on.

And the alchemy furnace is a magic weapon that is very resistant to temperature, Wen Jingxin and Sun Yanfei are the most talented in alchemy among the four generations, and they are also the descendants of the four generations, so the alchemy furnace on the two of them is the lower grade of the law level. It is enough to just fly above the magma, and the isolation of the alchemy furnace is also particularly good.

So, the four of them were divided into two teams, Mu Xiaotian and Sun Yanfei sat in Sun Yanfei's gunwei furnace, the lid of the furnace was put away, and the two of them stretched out half of their bodies. Sun Yanfei used Zhenyuan to control the gunwei furnace, and used the body protection qi to protect the upper body of the two.

And Wen Jingxin and Ma Xingye are the same, driving another alchemy furnace. Because Wen Jingxin is stronger, Wen Jingxin is responsible for collecting the spiritual fire, and Ma Xingye is in charge of the alchemy furnace.

The two teams split up and flew towards the volcano from different directions. After flying more than 100 miles, Mu Xiaotian saw a flame that was yellow, which was extra conspicuous in the magma. Mu Xiaotian was very happy, and Zhenyuan ran to his right hand and formed a claw shape towards the flame. Taking things from the air, the spiritual fire slowly floated towards the palm of Mu Xiaotian's hand.

Mu Xiaotian's right palm was facing upward, and a small flame floated above the palm and burned. Sun Yanfei and Mu Xiaotian glanced at each other and smiled. This was a spiritual fire of the spirit level, and Mu Xiaotian hurriedly put it away with a special box.

He flew further, collecting a large amount of spiritual fire along the way, and the closer he got to the volcano, the higher the level of spiritual fire.

The four of them were very fast at first, but when a spiritual fire above the law level appeared behind them, they slowed down a lot. The four of them searched one area after another, and did not let go of any spiritual fire. After all, the spiritual fire of heaven and earth is relatively scarce for the overseas immortal cultivation world, and there are relatively few fire veins overseas.

Although the search of the four people was more detailed, there were still fish that slipped through the net. The magma was piled up too deeply, and some spiritual fire was hidden in the magma. In this poisonous environment, Mu Xiaotian and Wen Jingxin did not dare to dive into the magma.

At this time, after Mu Xiaotian flew to a place, he found that there was not a single spiritual fire appearing. Mu Xiaotian was furious, and stretched out his right hand to palm the magma below. Bang, suddenly magma shot out, and some of them splashed on the alchemy furnace. The magma shot at Mu Xiaotian was blocked by the protective body of the Gang Qi, but the Gang Qi was slightly corroded.

Sun Yanfei screamed miserably and shouted loudly: "Oh, senior brother, this magma plus the black qi in it can corrode the divine thoughts and the gang qi. ”

Although Sun Yanfei was a little painful, when he saw a law-level spiritual fire appearing on the magma, he immediately became happy, and hurriedly asked Mu Xiaotian to collect it.

After Mu Xiaotian finished collecting it, he glanced at Sun Yanfei with his eyes, and then said, "Senior brother, fly up." ”

"Oh, fly up, what do you want to do, you won't be ......" Sun Yanfei looked at Mu Xiaotian in some surprise, and before he could finish speaking, he saw Mu Xiaotian stretch out his hands and look at himself, looking like he wanted to palm. Sun Yanfei didn't dare to stay, and immediately flew the alchemy furnace into the air.

Mu Xiaotian saw that the height was about the same, and shouted loudly with great excitement. The left hand and the right hand took turns to make a palm, and then circled around the gunwei furnace, making a total of more than ten palms. Each palm punches a pit of magma, with magma on the surface and magma at the bottom flipping. For a while, the magma under the alchemy furnace flew everywhere, but fortunately, the alchemy furnace was high enough.

After all the magma fell, Sun Yanfei slowly lowered the alchemy furnace. Originally, there were no spiritual fires floating on the surface of the magma, two of which were of the upper grade of the spirit rank, and one of the lower grade of the magic rank.

Seeing that this method was very good, after that, every time Mu Xiaotian collected the spiritual fire on the surface, he would slap a few palms at the magma.

On the other side, Wen Jingxin and the others also slowly mastered this method. Although the speed at which the four of them collected the spiritual fire became slower, the speed at which they collected it became faster.

Because the higher the level of the Spiritual Fire, the more difficult it is to collect the objects from the air. So after six hours, the four of them couldn't hold on. So the alchemy furnace could only fly high, and the higher it went, the thinner the black gas became. Stop at a high altitude and restore the true element. In order to speed up the recovery of the True Yuan, constantly use the True Yuan Pill, as well as take out the medium-grade spirit stone to absorb it.

An hour later, the four of them fell again and began to collect the spiritual fire. At this time, it was less than three hundred miles away from the volcano, and there were more and more spiritual fires above the lower grade of the Law Rank, and it was even more difficult to collect them. As a result, the speed of travel has become slower.

Another day had passed, and the four of them had already marched to the foot of the giant peak. At this time, the temperature at the foot of the mountain was very high, and although there was an alchemy furnace to isolate it, it did not dare to be too close.

But the spiritual fire level here has already reached the treasure level, which stimulates the passion of the four of them. Even if the true yuan is exhausted, the spiritual fire must also be collected.

With the efforts of the four of them, there were a lot of harvests during this time, no less than two hundred spiritual fires of the spirit level, nearly a hundred spiritual fires of the law level, and ten spiritual fires of the treasure level.

The four of them secretly thought: So many spiritual fires are a huge addition to this sect. Xuan Ling Sect has accumulated for thousands of years, and the number of spiritual fires is estimated to be about the same as the number of spiritual fires on the four of them now.

With so many spiritual fires, the fire storage boxes on the four of them were almost used, and before entering the secret realm, they didn't calculate that they could receive such spiritual fires. The spiritual fire of the spirit level is better, although the four of them don't know how to refine weapons, but they still have this ability to refine a box that stores the spiritual fire of the spirit level. Of course, the refining of the four people led to the loss of a lot of spiritual materials.

However, the spiritual fire of the Law Rank and the Treasure Rank is not easy to handle, and the required fire storage boxes are of higher quality, and the fire storage boxes used to store the Treasure Rank Spiritual Fire are only carried by the four people. plus the two Wu Ren and Zhao Qian who were killed before, there are four of them, and there are twelve in total. Although the fire storage box was relatively easy to refine, there was no way for the four of them to refine it.

There is no way, first store the spiritual fire of the middle and upper grades of the law level in the fire storage box, and put the remaining spiritual fires of the lower grade of the law level in a fire storage box, or some of the more common ones are placed in the fire storage box where the spirit level spiritual fire is placed, so it is reluctant to store the spiritual fire of the law level. The higher the level of the spiritual fire, the more it cannot be too close to each other, and the lower grade of the law level can at least be stored for a short time. Those above the middle grade of the Dharma rank cannot be stored together in any case.

Another five hours passed, and the four of them slowly walked to the summit. During this journey, the four of them collected more than 20 spiritual fires of the Dharma level, as well as five spiritual fires of the treasure level, two of which were still high-grade spiritual fires of the treasure level.

So the four of them have no place to store it, and they are reluctant to throw it away. So the four of them redistributed the law-level spiritual fire, and the rest had to be put into Sun Yanfei's first-level spirit level alchemy furnace. Mu Xiaotian set up a formation in the alchemy furnace to isolate the spiritual fires from each other. The remaining three treasure-level spiritual fires were placed in Wen Jingxin's alchemy furnace, and they were also isolated by formations.

These methods are not long-term solutions, but they can at least last until they leave the secret realm. Once he left the secret realm, he was immediately handed over to Mu Qingshan, a Daojun monk, to deal with.
