The ancient tree that became smaller into a bonsai looked like a flash of green light, and flew directly into the Zhentian seal in the hands of the thousand-year-old acacia.

"Okay, please take back the Divine Seal, and the old man will go with you." The thousand-year-old Gu Huai turned around and handed over the divine seal with both hands.

"Senior, I want to ask, what is the situation in the space inside this Zhentian Seal?" Li Ming took the Zhentian seal and asked curiously.

"The inside of the Divine Seal is gray, and the space is vast, but it's a pity that there is no master to help it arrange it properly, which wastes the role of the Divine Seal." The thousand-year-old acacia replied.

"There's a lot of room...... Then please help me manage the Divine Seal. Li Ming asked excitedly.

"The old man also thinks, it's a pity that the Divine Seal is already your treasure, and we can only live temporarily, but we can't have the ability to control it." The thousand-year-old Gu Huai shook his head, and his body turned into blue light and flew into the Zhentian Seal.

"Don't think too much, the Divine Seal is the same as the Divine Sword, once it enters your package, it will only recognize you as one owner, we can only borrow it, but we can't become its new owner." The saint shook her head and laughed.

"It's going to be like this, but I don't have any hints." Li Ming said stunned.

"Ancient gods are scattered all over the world, and those who are destined to get them can become the master of the gods, but unfortunately, when you obtained the divine seal, I was just a wisp of divine soul, and I couldn't become its master, but fortunately, the witch was not by your side." The saint said lightly.

"If I can control the Divine Seal, what kind of divine power do I think will be needed?" Li Ming asked curiously.

"The Zhentian Seal is an ancient treasure, and it takes at least an elder-level priest to control it, and in terms of our cultivation time, I'm afraid you need five hundred years of cultivation to reach the ability of an elder-level priest." The saint laughed.

"Okay, let's go back." Li Ming said stupidly.

Drip, drip!

Just as Li Ming took out the scroll to return to the city and was about to return directly to the Divine Craftsman Cave with the Holy Maiden, the private chat application suddenly jumped out.

Applicant: Tianxinhong!

At this time, Hong Shao asked for a private chat, could it be that there were really other discoveries in the demon cave?

Li Ming hurriedly connected to the private chat......

"Understand brother, good news, we have really found the ore vein, look at ......" Tianxinhong's private chat application was approved, and he exclaimed excitedly and sent out a screenshot of the system.

"What is this......" Li Ming couldn't help but widen his eyes as he looked at a black spar shown on the screenshot......

Ink Earth Spirit Crystal: A system prop, a rare spirit source crystal, containing mellow earth-based spiritual power, which can provide sufficient spiritual power support for large mechanism equipment.

……

"Ink Earth Spirit Crystal? Lingyuan Crystal ......" Li Ming looked at the attribute introduction, and his brows suddenly rose......

Let me go, this is actually a special ore that the official once mentioned in the advertising video before the start of the service!

The so-called ink earth spirit crystal, in fact, is a rare ore designed by the system according to the coal resources in the real world, after the use of the ink earth spirit crystal can provide sufficient power for large machinery, whether it is a sea giant ship or an airship, or a crazy iron armor rushing car on land, it seems that the ink earth spirit crystal is needed as a source of power!

No wonder Tianxinhong was so excited, it turned out that he had discovered this rare vein......

"It's really lucky that we found the Ink Earth Spirit Crystal so early!" Tian Xinhong said excitedly.

"It's not too early, soon we will all be level 50, all kinds of advanced maps will be opened one after another, and all kinds of mechanical maps will continue to be obtained, this demon cave task is prepared for us to discover the ink soil spirit crystal!" Li Ming said with a smile.

"Brother Understand, this ore was discovered by our own people, on a hidden stone wall in the deepest part of the Demon Cave, there are very few ore veins found at present, it is estimated that it will take people to carry out large-scale excavation to know the scale of the ink earth spirit crystal vein, I plan to ......" Tian Xinhong smiled, and suddenly stood up.

"Are you going to share this secret with the Imperial Wolf Blood?" Li Ming lowered his voice, his eyes flashing with a sly light.

It would be a shame to share such an important resource......

If the old fox of the Imperial Wolf Blood has the right to use half of the Ink Earth Spirit Crystal, the Imperial Dynasty will rise rapidly in the future!

"That's exactly what I thought, fortunately, the Ink Earth Spirit Crystal Vein was discovered by our own people, and we can cover up the past by finding a way." Tian Xinhong said.

"But Uncle Wolf, this old fox is not so easy to fool, if he personally sends someone to check again, you can't hide it even if you want to, unless there is a way to distract him." Li Ming frowned and said.

"That's why I talked to you privately, I want to borrow your mine hoe to use, and then there is good news, this demon cave is not only a kind of information about the ink soil spirit crystal, but also a mineral vein has been found in advance, Uncle Wolf is over there to check, as long as this side can hide the past, it will be easy to say in the future." Tian Xinhong said excitedly.

"What...... And a vein? Li Ming asked in surprise.

"Yes, but it's not so precious to take out the ore vein, it's a mid-grade strengthened ore purple lazuli vein, although it is not as precious as the ink earth spirit crystal, but it is also a very valuable ore." Tian Xinhong said with a smile.

Li Mingke was very clear about the purple lazuli he was talking about, thinking that when he was looking for the corpse-devouring dragon's lair, he accidentally discovered a vein of lapis lazuli's primary strengthening material, which was a proposal for cooperation and development with the Tianxin Alliance.

Weapons and equipment in the spirit world can be strengthened, and the enhancement +1+2+3 requires the use of lapis lazuli, which can improve the basic attributes of the equipment or weapon after success, and make the appearance stand out from the crowd, exuding a white halo.

Including Li Ming's Heavenly Mandate Staff, it is currently only strengthening +3, and as for +4+5+6, intermediate enhancement stones are used...... It is the purple lazuli vein discovered by Tianxinhong this time!

The production of such enhancement stones in the spirit world is extremely low, and may only be found in large quantities in high-level maps, but it is still very rare.

Therefore, this ore is actually very valuable, and it can greatly improve the basic strength of players.

But in contrast, Tianxinhong would rather share the purple lazuli than share the situation of the ink earth spirit crystal with the emperor to know.

"Yes, I will mail you the mine hoe immediately, you act carefully, if you can't hide it, forget it, so as not to affect the cooperation between the two sides." Li Ming said thoughtfully.

"Don't worry, we have the most people in the Demon Cave, there is no problem to hide from them, with the help of your mine hoe, and then find a way to cover up the existence of the Ink Earth Spirit Crystal, they will never think that this Demon Cave has such a precious second vein." Tian Xinhong said excitedly.

"Got it." Li Ming ended the private chat and immediately mailed the mine hoe to Tianxinhong......

This time was the last stop of his Demon Cave mission, and he didn't expect the harvest to be so powerful, it really exceeded his expectations.

The Demon Cave in the Elite Challenge Map is really extraordinary......

Li Ming crushed the scroll back to the city, and the holy maiden disappeared in an instant, and he also turned into a pillar of light and dissipated in an instant, and immediately appeared in front of the selected Divine Craftsman Cave Heaven Stone Tablet in the next second......
