With extremely tired body and mind, Lou Yi came to the area where Li Gan was. After leaving the elixir bottle and a piece of paper, he returned to his residence and fell asleep. Li Gan looked at the several elixir bottles in front of him, and when he saw the things written on the paper, the expression on his face was very complicated.

He looked at the bamboo house where Lou Yi was and bowed three times to it. Tears fell down the corner of his eyes, but he did not say anything, but grabbed the Dan Ping and went back to the house. Although Lou Yi asked him to adjust his condition a few days ago, saying that he had something for him.

But he didn't expect that Lou Yi was helping him refine elixirs during this period. And when he saw the Huo Li Dan contained in one of them, he could imagine his inner excitement.

After sleeping for two or three days, Lou Yi woke up. The first time he woke up, he went to see Huo Yan. Huo Yan was not in the room at this moment, so he went to find the iron cannon again and found that the iron cannon was not there.

When he came to the smelting room, he found that all the clever parts were missing. Lou Yi could roughly guess where he was, so he walked towards the back of the smelting room.

When Lou Yi looked at these parts, he once saw a secret door hidden behind the smelting furnace. But he was too tired at the time and had no intention of taking risks. Now he happened to have this opportunity, so he felt it was time to go in and take a look. Maybe the iron cannon, Huo Yan, and Li Chuang, who had never appeared, were all there.

There was a small path behind the furnace. At this moment, the secret door was opened, so he didn't have to worry about it. The road behind us was much more spacious than we thought, and the color of the soil was red.

The passages on both sides are about three or four meters wide, and it is very hot here. Perhaps because they are close to the fire vein, you can see many holes, each with a diameter of about a foot wide, which should be used for ventilation.

Walking along the passage, there was a lot of space next to it, with all kinds of discarded materials piled up inside, shining with a faint light. These should be all scraps and were thrown here randomly by iron cannons.

However, once it is useful, these things will naturally come in handy. The more you go, the steeper the road, and gradually a huge underground cave in a circular shape appeared in front of him.

"This...there are such a good place!" Lou Yi said in surprise.

He looked up at the distance, a red color ban enveloped here, and fire pillars gushed from below, and were sent to the place where the furnace was located. The surrounding temperature was very high, but the passage where he was located was relatively cool.

Looking down along the column of fire, there was an extremely huge lava lake. It kept rolling and splashing slurry hundreds of meters high. Lou Yi was inexplicably excited because this was Li Gan's most ideal breakthrough place.

Thinking of this, he accelerated his pace and walked down the ring-shaped passage quickly. Every time he stopped, because he felt Li Chuang's breath, and what surprised him was that there was actually the breath of the golden spirit vein here.

With curiosity, he went with the other person's breath. After seeing an amazing scene, no other cave appeared not far from the underground magma lake, but it was not formed naturally.

Lou Yi saw various fragments of spiritual weapons and were randomly discarded here. The gold energy here is extremely rich, and it is simply considered a tomb for refining weapons. The one who caused all this should be iron cannons.

There was a rumor at the beginning that if the spiritual weapon refined by Master Iron had flaws, even the best spiritual weapon would be destroyed by him. When you see this dazzling array of broken spiritual weapons, you can imagine the truth or falsehood of this rumor.

In the middle of the pile of waste tools, a circular table appeared. In fact, a elixir furnace was placed in the middle. Li Chuang flashed with a metallic luster all over his body. Lou Yi noticed that his left arm and left leg were still empty, and he couldn't help but feel confused.

But when he saw two pairs of prosthetic limbs placed not far away, he immediately understood that the first pair was naturally prepared by the iron cannon, and the second pair should have been made by Huo Yan a few days ago.

Lou Yi walked forward and took back the prosthetic limb made of iron cannon, leaving only what Huo Yan did. He didn't want Li Chuang to become like iron cannon in the future, so he would suffer a lot of losses.

After walking out of here, I continued to walk down. This time I saw the full view of the lava lake. The temperature here is extremely high, but I can still see two figures located here.

The iron cannon was soaked in the magma lake, and the metal parts on its body were melted by high temperature. At the same time, the iron cannon was extremely red, looking like cooked shrimps. Huo Yan carefully installed the clever accessories on his body.

Then the high temperature of the lava removes the residual toxins on the metal. The Cold Chi Dan refined by Lou Yi is now working. The fire poison is attracted by the lava and slowly flows out from the metal meshing point, and is then absorbed by the lava.

On the other hand, the Liuli Dan was also exerting its power in the iron cannon at this moment. They were eroding the blood stasis and poison in the iron cannon and cleared all the remaining toxins. Huo Yan looked very uncomfortable, but he had no scruples.

His skin was scorched by high temperature, emitting a copper-colored light. His expression was very focused. Lou Yi originally wanted to ask if he could check the fire veins here, but now he already had the answer. Li Gan could definitely use this place to break through the Danjie period.

Lou Yi stood quietly by the side and waited, watching him fusing parts and iron cannons together, metal threads that were almost invisible to the naked eye, sewing bones and muscles together with these parts. At the same time, he pretended to be these clever prosthetic limbs. After three hours, the iron cannon's body was completely renewed.

Although there is something strange from the outside, the new body is obviously much whiter, but overall it is much more pleasing to the eyes than before. Because the left eye of the iron cannon is blind, he still has an iron mask attached to his face, which looks no different from the previous ones, but it is much more practical than before.

Lou Yi saw him take out a red energy ball and stuff it into the left chest of the new body of the iron cannon. A red light flashed, and a flame pattern slowly spread, and the iron cannon's body shook violently.

Huo Yan, who had all this last night, quietly breathed a sigh of relief. Now it depends on when the iron cannon will wake up. He looked back at Lou Yi and asked, "Is there anything wrong with me?"

"I want to borrow this place." Lou Yi said straight to the point.

"Yes!" Huo Yan didn't say anything.

"Thanks......"

"You're welcome, I'm the one who wants to say thank you."

Neither of them said anything, Huo Yan was still guarding the iron cannon. Lou Yi turned around and walked back. He wanted to bring Li Gan over. Huo Yan watched him leave, his eyes flashing, as if he had made up some decision.

Lou Yi returned to the bamboo building and felt that Li Gan's cultivation had been perfected. It seemed that the three-step pill was indeed magical. Of course, the pill that Xue Wangqing gave him was also very good. Li Gan's anger was much stronger than before, which should be due to the increase in the purity of the fire spirit vein.

Lou Yi briefly told him and took him to the underground fire vein. Li Gan entered here, and his whole body was filled with a strong fire aura. He liked the environment here very much and couldn't wait to go down to the deepest part.

Lou Yi took him to the edge of the magma lake. Huo Yan glanced at him and reminded, "This magma lake is extraordinary. I suggest you start trying on the edge first, and then slowly try to go deep into the central area."

Li dared to start and said, "Thank you, thank you very much!"

Huo Yan shook his head and said, "No need to thank you, these are all his credit..."

Huo Yan looked at Lou Yi, then at Li Gan, hesitated for a while, and finally spoke, "Master Tie said that there seems to be a fire crystal ore vein in the center of this lava lake. If you can tolerate this high temperature, you may have unexpected gains..."

Lou Yi and Li Gan were both stunned for a moment. Fire crystals are a good thing, and they are higher-level existences than Feng Ling Stone. If Li Gan really succeeds, it means that his weapons after forming the elixir are in place. Speaking of which, his two big axes were damaged last time when they were in Yangjiatun.

Li Gan looked a little eager to try, Lou Yi reminded, "Everything goes with the flow, don't force it."

Li dared to go to the opposite of them, sat cross-legged on the periphery of the lava lake, and a large amount of fire aura was absorbed into his body, and his body began to slowly wrap a layer of red fire light.

Li Gan started to form a pill, but no one could guess the result. After all, Lou Yi had done everything for him. Next, it depends on his own luck. If he succeeded in forming a pill, then there was hope for the Nascent Soul. After all, after taking the Huo Li Dan, his fire vein purity increased by 30%, and now he is the peak of the earth vein. According to what Bai Ye said before, the Nascent Soul can be expected if there is enough opportunity...

Lou Yi returned to the top, Huo was still standing by the iron cannon. Lou Yi found Bai Ye and asked about some confusion in cultivation. Bai Ye knew everything, and the two discussed it early the next morning.

In the days that followed, when Lou Yi was doing nothing, he would refine elixirs. Anyway, he picked up the free alchemy furnace and did not refine it. His alchemy skills were also steadily improving. At the same time, he would take time to see the two brothers.

Li Chuang's aura became even stronger. Lou Yi felt that he was about to break through. A metal storm occurred around him. The residual weapons were swaying around. Lou Yi didn't dare to get too close to the other party. After observing from a distance for a few seconds, he confirmed that he had nothing to do before walking back from there.

Following the ring-shaped passage to Huo Yan, the iron cannon seemed to have recovered its consciousness, so Huo Yan pulled him out of the lava lake, but the iron master seemed to be still sleeping, his breath was much stronger than the previous two days, and he should be able to wake up soon.
