My Optimized Immortal Life

During the Qi Refining Stage, Chen Qing had a deep understanding of the lack of spiritual energy in Luo Yun Mansion. Now that he had spiritual awareness, he could observe even more subtle details.

At the edge of Luo Yun Mansion, because the concentration of spiritual energy is lower than that of the mansion connected to it, the spiritual energy in that mansion will slowly overflow towards Luo Yun Mansion. In Chen Qing's consciousness, the spiritual energy near him is slowly converging into Luo Yun Mansion. This situation is more like something is slowly absorbing spiritual energy from the surrounding area.

However, Chen Qing could not sense any trace of the formation at all, and as far as Chen Qing knew, even a Nascent Soul cultivator could only mobilize the spiritual energy of heaven and earth within a few miles. If it was a fourth-level formation, it would at most affect a few miles around the place where it was set up. As it was now, it could affect the land of an entire prefecture, a territory of dozens of miles. It seemed that only a fifth-level formation existed.

Chen Qing took a deep breath and used the Qi-gazing technique. Suddenly, the direction of the earth veins in the entire mansion appeared before his eyes. He saw several deep yellow earth veins extending to the easternmost part of the mansion.

The fifth level, the Spirit Transformation Level, is a cultivator who truly stands at the pinnacle of the human world and is a true free and easy person. If such an existence is deployed here in Luo Yun Mansion, it is definitely not something that Chen Qing can easily contact.

Chen Qing let out a light breath, slowed down his thoughts and calmed himself down.

Even if a Jindan cultivator really left something here, it is not something that a low-level cultivator like Chen Qing can easily access, so there is no need to worry too much.

Gazing at the mountains that rose and fell and stretched to the end of his sight, Chen Qing waved his hand and cast a spell, allowing the originally hovering flying boat to move forward again and disappear into the mountains.

Sky Valley.

This place is several miles in size, surrounded by several small hills and with several rivers flowing through it. It should have been a paradise, but in this valley, there is a crack that is several miles long running through the entire valley, dividing the valley into two.

With the help of the Qi-gazing technique, Chen Qing could see at a glance that above the wide crack in the ground, there were extremely obvious remnants of the Earthly Evil Qi and Earthly Fire Qi, which indicated that there was indeed an Earthly Fire Vein beneath the crack.

Chen Qing drove the flying boat and arrived at the Sky Valley after a few incense sticks. When he got closer, he found that the crack was even bigger than he had imagined.

It is several miles long and hundreds of meters wide. The widest part is almost one mile.

The crack under the ground is extremely deep. Even if Chen Qing uses his spiritual sense to explore it, he cannot fully understand the situation inside.

After thinking about it, Chen Qing did not drive the flying boat directly into it, but found a small hill next to it and landed.

Although the Qi-gazing technique records that the Black Nether Stone can resist the Earthly Evil, Chen Qing has never seen it with his own eyes, so he cannot just fly into it casually. Moreover, there are veins of earth fire flowing through this place. If he is careless, even Chen Qing, a foundation-building cultivator, may die here.

The crack in the ground here is so huge that it is too risky to drive a flying boat into it. It is better to dig a tunnel next to it and go straight down to avoid the invasion of underground fire.

As his thoughts turned, Chen Qing turned around and flew away from the mountain, landing in the nearby jungle.

After entering the foundation-building stage, the cultivator is already able to fly with his own magic power. However, due to limited magic power, it can only support short-distance flight. Therefore, Chen Qing still drove the flying boat here, but to explore the surrounding terrain, it would not be a problem to fly on his own.

After walking around the entire Sky Valley and getting a general understanding of the surrounding situation, Chen Qing stopped.

The entire Sky Valley is at a low altitude, and the surrounding hills are not very high, only a few dozen feet in size. However, this place is covered with dense forests, with many snakes and insects, and even many ferocious beasts such as giant insects.

This is definitely a dangerous place for mortals, but it poses no threat to Chen Qing.

It is naturally impossible for monsters to exist in this area. Even if there are, they have long been killed by the wandering cultivators in Luo Yun Mansion. After all, there are scarce resources for cultivation here, and monsters are full of treasures, so the cultivators here naturally will not let them go.

After finding the lowest place, Chen Qing prepared to dig a tunnel. For a cultivator in the Qi Refining Stage, digging a tunnel could be done with the help of magic tools and spells. However, at this time, Chen Qing had already become a Foundation Establishment cultivator, so this kind of thing was naturally even simpler for him.

He cast a spell and the ground opened up, revealing a hole that was several square meters in size.

Chen Qing took out the formation flag, set up the formation at the entrance of the cave, and then walked into the cave.

The power of spells cast with the magic power of the Foundation Establishment Stage is naturally greater than that of the Qi Refining Stage. Although the hole opened up is not big, the inside extends several feet underground.

However, Chen Qing did not plan to use this spell to dig tunnels all the time. After all, there was a lack of spiritual energy here, and his mana would recover more slowly after being consumed than in Hualiang Valley. It would still take less mana to drive the flying sword to dig.

He used the flying sword to dig the soil and rocks, collected them in the storage bag, and then continued digging. In just a few hours, Chen Qing had traveled nearly seven or eight hundred meters underground. With the help of his spiritual sense, he could clearly know everything within a radius of four hundred meters, so the direction of excavation would not deviate.

When Chen Qing left, he gave Xu Lingxin a large amount of spirit stones, enough for her to rent a retreat room in Hualian Valley to practice for several months. Therefore, he could dig here for more than a month until he found the vein of the earth fire.

But in reality it is not that troublesome. A month is enough for him to dig down dozens of miles. The vein of underground fire is obviously not that deep, otherwise it would not gush out from the cracks in the ground so often.

The excavation work lasted for seven or eight days, and Chen Qing also opened up a distance of several miles downwards. During this period, he had not seen the Earthly Evil erupt once, so his idea of ​​verifying whether the Black Nether Stone could resist the Earthly Evil was naturally in vain. However, with the help of the Qi-gazing technique, he found that he was getting closer and closer to the Earth Fire Vein.

Two days later, Chen Qing used his flying sword to chisel open a rock wall. Suddenly, the scene in front of him became bright. He looked forward and saw a fiery red lake in front of him.

It turned out that Chen Qing had used his spiritual sense to find a cave formed by the erosion of the earth fire veins. At this time, he had broken through a rock wall bordering the earth fire.

Looking at the lake of underground fire in front of him, which was dozens of feet in size, Chen Qing's face was filled with excitement.

After finding the vein of earth fire, he will be able to use his skills to refine the essence of earth fire and thus improve his cultivation.

Moreover, since Chen Qing dug a tunnel himself to get down, he avoided the Earthly Evil Spirit. The flying boat originally prepared with the Black Nether Stone might be useless.

However, the cave made of black stone can also be used.

Next, Chen Qing opened up a space of more than ten square meters next to the tunnel. In order to avoid being affected by the possible eruption of the underground fire veins, he also reinforced the rock walls near the cave so that they could withstand the heat of the underground fire without being melted.

After arranging the cave, he breathed a sigh of relief and looked at the almost inexhaustible lake of underground fire in front of him. He suddenly felt that the road to success was just around the corner.
