Immortal Path Evergreen

Although Wei Zongxun is young and his cultivation is only at the first level of foundation building, his status in Qingxuan Sect is relatively high, not less than Han Yan when he just built his foundation.

He is a rare formation master in the sect. Once such a talent grows up, it will be of great help to Qingxuan Sect. Once he can advance to the fourth-level formation master, even the old ancestor Jin will give him a lot of face.

Therefore, even though the cultivation level is far apart, Zhang Zhixuan did not dare to neglect it along the way and respectfully invited Wei Zongxun to the family.

With the continuous conversation with Wei Zongxun, Zhang Zhixuan also had a little understanding of the process of opening the fire eye.

Although the earth fire is stable and the burning temperature is extremely high, it is a pity that it is not as pure and clean as the true fire of the cultivator. There are countless mineral vein impurities in the earth fire, which will become the earth lung poisonous fire after smelting day by day.

This earth lung poisonous fire is colorless, tasteless, invisible, silent, invisible, and will be mixed in the ordinary earth fire. Unless some cultivators practice fire attribute skills, it is almost difficult for ordinary people to distinguish.

The poisonous fire underground is extremely poisonous and troublesome. Once infected, even high-level cultivators such as Zifu Jindan will leave hidden dangers that are difficult to solve if they cannot eliminate it immediately.

So if you want to open the fire eye, the first step is to purify the ground fire and exclude the ground lung poisonous fire. If you want to purify the ground fire, you must arrange the formation, and you need a third-level magic weapon that is not afraid of the ground fire smelting to serve as the formation eye.

In addition, the temperature of the ground fire is very high, and ordinary materials will be easily smelted and cannot be used for too long.

The materials for building the fire room must also use very good refractory materials, which often requires the help of a third-level refiner to smelt. However, the Zhang family has Zhang Sidao, a third-level refiner. In order to build the alchemy room this time, Zhang Sidao also followed Zhang Zhixuan back to the mountain to help.

In the three southeastern counties, the best refractory material is the fire brick invented by Qingxuan Sect. This refractory brick uses thirteen materials such as refined copper, black quartz, white crystal, and clay, and can only be smelted with the true fire in the cultivator's body.

The formula of the fire-removing brick has been kept secret and not passed on to the vassal foundation-building families. However, in order to build the underground fire room, the Wu family also asked the weapon refiners in the sect to help refine the fire-removing bricks. With the precedent of the Wu family, Zhang Zhixuan can also ask Sidao to help refine the fire-removing bricks.

Sidao has been building the foundation for fifteen years and has learned the refining methods of more than a dozen third-level magic tools in the Qingxuan Sect. Because Zhang Zhixuan notified him in advance, he also spent 200 good deeds to learn the refining method of the fire-removing bricks.

As long as the Zhang family finds the materials, Sidao can sacrifice the fire-removing bricks at home.

The materials for refining fire-removing bricks include both refined copper and black Ying stone, which are spiritual objects for cultivators to practice, and clay and white crystal, which are earthly veins. After Zhang Zhixuan returned home, he immediately mobilized the cultivators below to start collecting materials and supply Zhang Sidao with them to refine fire-removing bricks.

This process took two years. In the two years, the fire-removing bricks refined by Sidao were enough to build three fire-refining rooms.

After the fire-removing bricks were successfully refined, the Zhang family spent almost three thousand spirit stones on this investment alone.

In the past two years, Zhang Zhixuan accompanied Wei Zongxun to visit the four spiritual veins of the family, and followed him to inspect the mountains and find a suitable place to open the fire cave.

Lingjing Mountain was ruled out first. Although the spiritual energy here is the best, it is a pity that the area is small. Once the ground vein is opened, the bottom fire will explode and destroy this exquisite spiritual mountain.

Wanshe Cave is not suitable here either. Although Wanshe Cave is underground, the amount of engineering work may be smaller. However, the strength of this spiritual vein is not enough, and it is also in the middle of the underground cold pond. Once the ground fire is opened, I am afraid that the conflict between water and fire will immediately cause a violent explosion and completely blow up the spiritual vein.

Moreover, a large number of Xuanyou grass are planted in the cold pond of Wanshe Cave. This spiritual grass is a very important source of income for the Zhang family. Unless there is no other suitable location, Zhang Zhixuan will not choose to open a fire cave here.

The final location was selected from the vast Jiuhua Mountain and Tiantai Peak. Tiantai Peak has a majestic mountain. If the fire eye is opened, it is necessary to completely open up the spiritual mountain. The amount of work required is too large and it may take decades.

Although Jiuhua Mountain is also a big mountain, its height is only one-tenth of Tiantai Peak. It is the most suitable location among the four spiritual veins of the Zhang family.

After selecting the place, Zhang Zhixuan immediately arranged for the monks to dig caves, preparing to slowly open up the ground veins and lead out the ground fire.

This kind of work can be completely handed over to ordinary mortals at the beginning. When the underground water source is dug out, it will be handed over to the Qi training period monks to drain the groundwater and continue to dig deeper.

The deeper you dig, the higher the temperature of the cave will be. In the end, ordinary mortals will not be able to hold on. After that, the excavation work will be handed over to the Qi training period monks. When it comes to the last thousand feet, because of the underground miasma, even the foundation building period monks will need to do it themselves.

In the past two years, Sidao refined refractory bricks while Zhang Zhixuan arranged people to dig fire holes, and Wei Zongxun also collected materials to refine the formation of purifying the ground fire.

All the work went hand in hand under the overall arrangement of Zhang Zhixuan. The fire bricks were placed in the fire holes, and then integrated into one by one using spells. The three fire refining rooms were already in good shape, and the excavation of the fire holes was almost at the point where the foundation-building cultivators needed to come forward.

In order to speed up the progress, Zhang Zhixuan, the clan leader, and Zhang Sihong, three foundation-building cultivators, personally came forward to dig the fire eyes underground.

As for Zhang Tonghuai, who had just established his foundation, he was sent to Chaoyin Mountain by Zhang Zhixuan to replace Zhang Sihong who was guarding the mountain. After all, he had just established his foundation and his magic power was insufficient. It would take some time for him to stabilize his realm.

Sihong has been building the foundation for almost ten years. He is a second spiritual root monk. He cultivates in a place with abundant spiritual energy like Chaoyin Mountain. He has broken through two levels in a row in ten years, far surpassing Sihong who built the foundation a few years earlier. road. In a few years, he will be ready to take the Miaozhen Pill and try to break through to the middle stage of foundation building.

Among the three, Zhang Zhixuan had the highest level of cultivation and the strongest mana. He was young and strong and quickly dug deep.

Another hundred feet can dig through the earth's veins and open the eyes of fire.

The power of the earth fire explosion was quite violent. Even if Zhang Zhixuan's magic power was half that of the Zifu monks, he would not be able to suppress such an explosion. The last step to open the fire eye is to trouble Qing Chan, who has the highest level of cultivation.

Qingchan had been preparing for a long time, and fired the Liuyang Crossbow continuously. After three arrows, he penetrated the earth veins and drew out the earth fire.

A strong explosion came from the eye of fire, and red hot lava rushed towards Qingchan along the eye of fire.

These streams of lava may be mixed with the Earthly Poison Fire. Even if Qingchan opens the Zifu, this Earthly Fire will still pose a strong threat to her.

After all, compared to the vast power of nature, Qingchan's magic power is insignificant, and it is difficult to protect himself from the base fire for too long.
