At the beginning, he brought back about two to three thousand yuan every hour, most of which were low-quality, with a small amount of medium-quality.

But as he continued to go deeper, the number of spirit stones in the ore increased, and the medium-quality ones also increased. This made Ling Tian a little excited, indicating that the amount and quality of spirit stones contained in this mine were very good.

A day later, Ling Tian could hardly hide his excitement because he discovered that this mine was definitely a super rich mine. There were a lot of high-quality spirit stones around the location where the Dragon-Slaying Vine was now.

Ling Tian was a little too excited while digging and didn't realize that the Dragon Slaying Vine had reached its maximum retractable range. He had no choice but to walk into the mine dug by the Dragon Slaying Vine.

He controlled the Dragon-Slaying Vine to continue working as he walked. When he reached the end, he continued to sit cross-legged in meditation, multitasking. On the one hand, he absorbed a hundred times more spiritual energy from the secret realm, and on the other hand, he controlled the Dragon-Slaying Vine to dig spiritual stones for him. I guess no one else could do this.

The hundred times concentration of spiritual energy may be a huge temptation to others, but for Ling Tian it is just better than nothing. With one infant and five bows, plus a strong physical body, the spiritual energy required to advance to a small realm is at least dozens of times that of others. If he wants to advance to the middle stage of the Nascent Soul, it will probably take hundreds of years if he relies solely on absorbing the spiritual energy here.

The Dragon-Slaying Vine continued to dig deeper and deeper, and the harvest became greater and greater. In just a few hours, at least tens of thousands of medium-grade spirit stones were excavated, and there were seven or eight thousand high-grade spirit stones. On the contrary, low-grade spirit stones were rare, which showed how great the reserves and quality of this vein were.

A day later, Ling Tian stopped digging. He sensed the presence of other cultivators several feet away from where he was digging. In order to avoid being discovered, he retracted the Dragon-Slaying Vine and started digging from the other side. At the same time, dozens of people from the Luoshen Sect were digging excitedly outside with pickaxes.

"Brothers, hurry up! The Wheel of Time Tower will open in three days. Don't miss it. Also, I'm in charge of the harvest of the mineral veins here. Just hand over 20% to me and bring it back for the task. Work hard! One day's harvest is equivalent to several years' salary from the sect."

Lin Minhao's words gave dozens of fellow disciples a boost of energy. They dug with all their might, but they were actually smiling in their hearts. The 20% they handed over to him would bring rich rewards. This place was full of dangers. Every time it was opened, there would be heavy casualties. Not many people could return to the sect in the end, so the share of the dead would all fall into his pocket.

Ling Tian had been using part of his consciousness to watch the actions of the Luoshen Sect. Fortunately, the route they were digging was gradually moving away from him, which made him feel relieved.

Although his combat capability is pretty good now, he is not arrogant enough to fight alone. Another thing is that this is a rich mineral vein. Once the information is leaked, he will definitely be in trouble.

Seeing them gradually going away, Ling Tian recalled what Lin Minhao had just said.

"I could give the Wheel of Time a try, but I'm not sure if I have enough time."

Ling Tian pondered for a long time and decided to make plans based on the progress of the excavation. After all, he now had a huge gap in his demand for spirit stones, and he had to get the information about the Heart of Space from Bai Xiaosheng. Everything had to revolve around this point. Hundreds of millions of high-quality spirit stones were no joke, and even ordinary large sects might not have such a huge fortune.

An hour later, he could no longer sense the presence of those people from the Luoshen Sect, so Ling Tian became bolder and released the Golden-winged Peng Eagle and the Divine Monkey to dig together. With the help of the two monsters, the speed of harvesting was several times faster. Especially the Golden-winged Peng Eagle, whose claws were extremely sharp, and its digging speed was no slower than Ling Tian's Dragon-Slaying Vine, but Ling Tian himself had to follow behind to pick up the spoils.

Ling Tian was very happy. Who doesn't like picking up money? As for the divine monkey, he didn't need to pay attention to it. It had already awakened its intelligence, and except for its appearance which had not yet completely transformed into a human, everything else was the same as a human cultivator. Using the space ring was a piece of cake for it.

Another day passed, Ling Tian smiled and narrowed his eyes. More than 500,000 high-grade spirit stones and more than 2 million medium-grade spirit stones, this was a huge harvest.

"What?"

Ling Tian, ​​immersed in joy, just received a message from the Golden-winged Peng Eagle that it had discovered a blessed land with a thousand times richer spiritual energy.

Ling Tian hurriedly ran towards the depths of a mine. After a quarter of an hour, he arrived at the place Xiao Jin mentioned. Looking at the one-foot-sized groove in the center of the cave, the thick white liquid inside made him exclaim in excitement no longer able to suppress his excitement.

“Spiritual Essence!”

"And it's a mid-grade spiritual essence. There must be a spiritual core underneath."

Ling Tian almost couldn't contain his excitement. This was unimaginable wealth. As long as he obtained the spirit core, it would continuously produce spirit stones. It could be said that as long as he possessed the spirit core, it was equivalent to him obtaining a spirit stone manufacturing machine.

"It must not be known to anyone else."

Ling Tian knew the importance of the matter, and immediately used a formation to enclose the hole. He even set up a sky-burning killing formation, with his seven-colored divine flame as the center of the formation. Once someone came in, unless they were a powerful god-transforming cultivator, they would definitely die.

Ling Tian took out a cold jade bottle and carefully collected the spiritual essence. A tiny hole was revealed at the bottom. Ling Tian knew that the spiritual core must be underneath.

In order not to damage the spirit core in the slightest, Ling Tian took out the Immortal-Destroying Sword and began to cut very carefully several feet away from the groove. It took him more than an hour to dig out the entire spirit core.

Looking at the irregular milky white spirit core that was the size of a baby's fist, Ling Tian was so excited that he protected it with both hands.

"I didn't expect the spirit core to be like this. It has no spiritual energy at all. It's really amazing."

Just as he was speaking, a lot of spiritual energy actually flowed into the spiritual core on its own, and next to it, a few wisps of crystal light slowly condensed. Upon closer inspection, it was found that this was a shrunken spiritual stone.

"The gains from this Void Crossing Secret Realm are unimaginable."

Ling Tian collected the spirit core and the dozens of top-grade spirit stones derived from it. Then he collected the densely packed high-grade spirit stones on the cave wall. When he was collecting them, he heard a movement outside. He knew that the people from Luoshen Sect were about to come in. Ling Tian couldn't let them detect any evidence of the existence of the spirit core. He ignored the high-grade spirit stones and used the Dragon-Slaying Vine to cause trouble.

While he was causing trouble inside, the outside of the formation was already filled with people from the Luoshen Sect.

"Everyone, work hard. This must be the cave of a powerful person. If you break through, you will definitely find all kinds of rare treasures."

Lin Minhao roared a little crazily and attacked the formation without reservation. His madness also inspired the fiery hearts of his fellow disciples, but they didn't know that what was waiting for them would be a hellish killing formation.
