Zuo Xu said to Chen Xin as he walked: "This is the second time I have come here, and the first time was the day before I took over as the head of the house, and the previous head led me here. This is one of the biggest secrets of the Heavenly Refining Sect, which can only be known by the head of the sect in the past generations. It's a violation for me to bring you here.

The two of them passed through a passage full of formations and spells. After passing through a stone gate. came to a huge circular space.

The semicircular dome above the space is densely covered with cavities about one meter in circles. It's like a beehive. Underneath is a bottomless cave. Chen Xin and Zuo Xu were standing at the edge of the cave.

Looking down, I saw golden lightning streaks passing by, which were generated by the collision of the golden force, and the more downward the lightning became, the denser it became, until it turned into a dazzling golden light. There is a chaotic Golden Force that has tended to substance. The wonderful thing is that the frenzied Golden Force only runs wild inside the cave. It was as if there was an invisible lid covering it, and not a single trace escaped from the cave.

Zuo Xu looked at Chen Xin and asked, "What are you sure to tell me now, do you really want to enter the Wanhua Cave?"

Chen Xin said affirmatively: "Yes, rest assured, I am sure, if I really can't hold on, I will definitely ask for help." And never to come here again!"

Zuo Xu nodded and said, "Okay, you see there's a staircase there, and I'll make a gap there." You take the opportunity to enter. Be careful!"

Chen Xin said, "Wait a minute!" and took off all the clothes on his body and put them on the ground. "That's it!"

Zuo Xu thought about the method, and slapped his palm on the ground! A crack appeared on the formation, and Chen Xin flashed forward. The crack closed instantly, and several bolts of lightning rushed out and slowly dissipated by Zuo Xu's casual grab. Zuo Xu shook his hand, and said in his heart, I rely on the attack power of the remaining five-grade magic weapon in this one! I couldn't help but look at Chen Xin worriedly.

As soon as Chen Xin entered the cave, he was struck by several bolts of lightning. These lightning bolts just look alike, but in fact they are nothing more than chaotic golden force, and the metallic energy generated by the collision is similar to sword qi.

The lightning left two deep wounds on Chen Xin's body, which disappeared into the wound.

Chen Xin has gone through three tribulations so far. The Tribulation of Tianwutang Wood, the Tribulation of the Void, and the Tribulation of Xin Xinghuo. Among them, the Wood Tribulation is the gentlest and easiest to complete.

The remaining two tribulations were all suffering, but Chen Xin felt that the golden tribulation was the most painful. The lightning stabbed Chen Xin and did not disappear, but entered his body, destroying the organs in his body. Thousands of needles are strung in the body. I can't be unconscious yet, I must face it soberly.

Ten steps down, step by step, this is already the limit. and then down to the intensity of the lightning. will make Chen Xin's recovery unable to keep up. That's dangerous!

Zuo Xu witnessed Chen Xin's body being injured and healing. Wounded again. In the two lightning bolts that had just burst out, Zuo Xu knew how much pain Chen Xin was suffering! While he was surprised by the magic of practicing physical exercises, he also admired Chen Xin's strong perseverance.

About five hours passed. Chen Xin felt that he was almost at the limit, and he stepped back step by step and returned to the edge of the cave, Zuo Xu opened the formation and Chen Xin jumped out.

Zuo Xu stared intently, and Chen Xin was dressed. Chen Xin's hair was stared at. I thought to myself, this old guy won't have any thoughts about me, right? He asked cautiously, "Master, can you not look at me like that?" I'm a little embarrassed!"

Zuo Xu smiled: "I was thinking, I just saw you underneath, and the little brother was obviously cut off." It's amazing how this will grow!"

Chen Xin was stunned and scolded in his heart, "You old rascal!"

The two walked out of Wanhua Cave, and Chen Xin asked Zuo Xu, "Master, are you ready for the red iron essence you promised me?"

Zuo Xu said: "It's ready! But there is less than 100 catties of stock in the warehouse." I have sent a mission to the outer gate to try to acquire hematite essence as best I can. There will be news in the near future. I don't think it's going to be a lot!Can you tell me what you need so much hematite essence for?"

Chen Xin smiled mysteriously: "Secret!" "A hundred catties is a bit less, I don't know how much hematite there is?"

Zuo Xu was stingy in his heart, and said in his mouth: "Hematite! There is a hematite mine outside the gate of Tianlianmen Mountain." ”

Chen Xin held the hematite essence, and a large amount of hematite stones. I came to the refining room. A refining furnace was taken out. Looking at the refining furnace, Chen Xin was full of emotion, you are the source of this turmoil!

After a portion of the hematite is placed in the refining furnace. Chen Xin took out the refining furnace again and began refining the Red Soldier Sand.

Zuo Xu was in the secret room, fiddling with a mirror-like magic weapon, muttering, just after such a painful cultivation. He started refining without stopping, this kid is really amazing. I'll see what you're doing? Hey, what's wrong with this magic watchman?

It was getting late, and Chen Xin returned to his residence tiredly, this day was really tiring enough. Chen Xin didn't know why he was pushing himself so hard! He didn't even look at Ni Shuang that day. contacted the potato and knew that Ni Shuang was busy with alchemy. I thought I'd go to see her tomorrow, and I just had something for her. Unconsciously, Chen Xin fell asleep.

The next day, Chen Xin first went to find Ni Shuang. and invited her to the Xuanjin Peak Refining Room.

In the refining room, Ni Shuang was very happy, dragging Chen Xin and talking non-stop.

Chen Xin listened quietly until she said enough. Ai touched Ni Shuang's soft hair and said, "I will be busy for a while in the future." I won't come to see you often, you have to pay more attention to your body, and let the potatoes pass on to me if there is anything. ”

"What's the matter?

"There's a sect ranking tournament in a year! It's about sect secrets, so it's inconvenient for me to disclose them! You won't be angry, right?"

Ni Shuang smiled: "How can I be angry! I'm not a child, this ranking tournament is related to the survival of the Heavenly Refining Sect." Everybody wants to contribute, but not everybody has the ability! I'm so happy and proud that you can contribute to the competition!"

"Our Ni Shuang is so good, give you a reward" Chen Xin said and took out a jade box and put it in Ni's hands.

Ni Shuang took the jade box and asked curiously, "What good things?"

"Open it and take a look!"

Ni Shuang opened the jade box, and a green flame the size of a baby's fist jumped and swayed gently in the jade box like a fallen leaf in the wind. "What kind of fire is this? It's so beautiful!"

Chen Xin said softly: "The void is immortal!"

Ni Shuang almost didn't jump up: "The void doesn't extinguish the fire!" ”
