The head of the Lan family resisted the excitement in his heart, first settled Yunfeng as a distinguished guest, and hurriedly called several elders in the clan to discuss. The details, pros and cons were weighed until the early morning of the second day.

During this period, Hu Xiaobai has been following Lan Haiyue, and Yun Feng is not worried about his safety, but just meditates and cultivates in the room by himself.

In fact, he didn't have much interest in the Lan family's sword technique, but Hu Xiaobai repeatedly instigated it, and besides, the team of the Phantom Sword Sect would not come to Xingyue City so soon, so he decided to take advantage of the trend. However, with Yunfeng's style of acting, he naturally would not do anything to harm the Lan family.

In the early morning of the next day, after a night of meditation, Yunfeng was full of energy and mana. Now his cultivation is firmly in the middle stage of foundation building, and it is difficult to make a big improvement in the short term. However, with the power of the spirit weapon of the Zixiao Fire Thunder Sword, coupled with the two Five Elements Treasures of the Xuanbing Water and the Burning Lotus Heart Flame, even in the face of the Dao Leader of the Yudan Period, Yunfeng has the power to fight.

The head of the Lan family had been waiting in front of the gate of Yunfeng Courtyard early, although he was a monk in the late stage of foundation building, and his cultivation was slightly higher than that of Yunfeng, but with the identity of the other party's Xueji Sect Taishang Elder, he naturally bit down his posture.

Seeing that Yunfeng had finished meditating, he dared to knock lightly on the door. The two of them are both sword cultivators, and after exchanging cultivation experiences, they have benefited a lot. During this period, Yun Feng saw that the head of the Lan family wanted to speak several times, and obviously had something to ask for, so he took the initiative to ask.

The head of the Lan family told the ins and outs of the matter without reservation, and looked at Yunfeng with hope. Yun Feng heard that there were ancient sword qi ruins, so he naturally would not refuse. However, he also took the opportunity to make a request to borrow the Lan family's sword pedigree.

The Lan family master only hesitated slightly, and then agreed to Yunfeng. After all, although the sword spectrum is important, if the family decay incense is not continued, the sword technique will become worthless. What's more, there aren't many Tiannan sword cultivators now, and there is no need to worry about the sword technique spreading in a large area.

In order to show his sincerity, the head of the Lan family even printed a copy of the sword trick on the spot and handed it to Yun Feng, as if he was not worried that he would break the contract. Yun Feng put away the sword technique, and was greatly moved in his heart, indicating that he would definitely do his best for this trip to the ore vein.

Both parties were overjoyed and set off about three days later. During this period, the head of the Lan family needed to secretly arrange the aftermath of the clan, and also prepare many formation materials such as formation flags.

Three days later, the sky was slightly bright. The head of the Lan family took several elite disciples of the clan, including Lan Haiyue, to the abandoned ore vein. In order to avoid the attention of others, Yun Feng also disguised himself and stayed at the tenth layer of the Qi Refining Period, mixing among the disciples.

The group traveled for several hours, and it was not until dawn that they reached the abandoned ore vein. There was already a person waiting near the ore vein, this person was of medium age, holding a whisk in his hand, and he was a late stage of foundation building, so he must be the best friend of the Lan family master.

The head of the Lan family rushed up to greet each other, and the two whispered a few words, and after discussing the countermeasures, they went to the entrance of the ore vein together, and the disciples of the Lan family hurriedly followed behind.

The entrance of the ore vein was guarded by dozens of elite disciples of the Lan family, and they came to pay their respects when they saw the head of the family. The head of the Lan family

After some explanations, he continued to lead everyone to the bottom of the mine.

If you want to reach the ancient waste mine, you must first pass through this metal vein operated by the Lan family. The crowd walked for half an hour, and did not stop until the darkness around them was out of sight.

The reason why the Lan family master did not ask someone to light the lighting rune was also to prevent being followed. In the dark, people's sensory perception is the most keen, and after confirming that everything is correct, they ask their subordinates to take out fluorescent stones and continue to move forward with the faint light.

After walking for about a quarter of an hour, the surrounding temperature was freezing cold, and the disciples in the Qi Refining Period had to activate the spiritual power shield to defend against it. Yun Feng guessed that they should be a hundred feet deep underground at this time.

Suddenly, a slight buzzing sound sounded, and the Thunderbolt Five Elements Sword behind Yun Feng reacted. The Thunderbolt Five Elements Sword is a Heavenly Spirit Weapon level, and its sense of sword qi is far sharper than that of humans, Yun Feng felt its cheers, and secretly rejoiced in his heart, presumably this trip will definitely have something to gain.

Secretly operating the Phantom Sword Duel, unexpectedly did not sense the slightest sword qi. With an idea, he used the ancestral sword technique given to him by the Lan family master, and suddenly felt an extremely kind sword aura calling him. He was just slightly moistened by the sword qi, and he suddenly felt refreshed and his spiritual power increased, this ancient sword qi was really extraordinary.

It seems that the Lan family master has already sensed it, but his face is as usual and he doesn't show it. This made Yun Feng deeply feel the depth of this person's city, and secretly became more cautious.

The group continued on their way, stopping until a hole emitted a golden light. The spiritual power fluctuation at the entrance of the cave is abnormal, and there should be a prohibition.

The head of the Lan family said to everyone: "It is the formation prohibition in front of me that has blocked Lan many times, with my cultivation, even if I continue to attack, I can't break it, and I must use the combined efforts of the three foundation building monks to have hope." ”

The head of the Lan family then instructed Lan Haiyue to lead the clan to arrange the formation, while he and another foundation building monk and Yun Feng meditated and breathed to achieve the best state.

After a stick of incense, all kinds of auxiliary formations were arranged, and the Lan family also retreated outside to wait, at this time, only the Lan family master, the dust monk, Lan Haiyue, Yun Feng and Hu Xiaobai, who had been sleeping on Lan Haiyue's body, were left at the entrance of the cave.

The head of the Lan family let Lan Haiyue protect the Dharma by his side, and the other three took out their weapons to attack the prohibition, as long as the forbidden spiritual power was exhausted, it could be easily broken.

Yun Feng didn't dare to use the Thunderbolt Five Elements Sword lightly, but summoned the Purple Sky Fire Thunder Sword to attack. Even so, the powerful spiritual power emitted by the Zixiao Fire Thunder Sword still amazed the Lan Family Master and the Dust Cultivator.

After all, he is a disciple from a great sect, and his shot is a spirit-level weapon, even if it is the master of the Lan family, it is just an ordinary treasure weapon.

Under the wild bombardment of the three of them for several hours in a row, the formation prohibition finally gradually collapsed. Yun Feng and the others were excited, and immediately entered the cave and found that this was the former site of an ancient sect.

Although the walls are ruined and devastated, you can still see the former glory of this place. Judging from the humanoid bones scattered underground, there should have been a great turmoil here back then, and it was wiped out overnight.

Everyone carefully searched all corners, the alchemy room, the practice room, the treasure pavilion and other places were ten rooms and nine emptiness. Occasionally finding a few well-preserved items also depleted with the passage of time.

After everyone had searched all the outer buildings, their eyes were focused on the main hall in the center. Yun Feng clearly felt that that ancient sword qi was coming from there.

Several people glanced at each other, the head of the Lan family was in front, Lan Haiyue was on his side, and the dust monk and Yunfeng were on both sides, and they walked into the main hall at the same time. They kept their distance from each other, after all, in front of Chongbao, father and son may turn against each other, not to mention just a few people who have a cooperative relationship.

Although the main hall is also a mess, there are many fewer bones than outside, and the building is relatively intact. The space in the hall is not large, and as far as the eye can see, all corners can be seen at a glance, and nothing unusual is found.

What's even more strange is that since entering the main hall, the Lan family's sword technique's induction of sword qi has suddenly disappeared, and only the thunderbolt Five Elements Sword is still emitting an imperceptible hum.

Yun Feng swept over the Lan family master with his afterglow, and found that his face was full of doubts, which did not seem to be fake. It seems that it is not only himself who has been affected, but perhaps there is some kind of mechanism formation hidden in the main hall, which isolates the monk's sense of sword qi.

Everyone carefully searched the hall, and finally unanimously stopped their eyes on the huge statue in the middle of the main hall.

This is a majestic humanoid statue, a dignified middle-aged man, who wants to bundle jade, holding a long sword, and looks like a sword fairy who is not a firework in the world.
