Lu Ding and the others wanted to cooperate with Liang Ji, so that as long as Liang Ji ushered in the Void Demon Group every time, they only needed to follow behind, guerrilla and hunt, and then intercept and pursue after the demon group was defeated, so that they could hunt a large number of third-order Void Demon Clans, earn a large number of spirit stones, resources, and credits, and complete the tasks in the Manggu Academy.

For them, it can be said that there is no harm in all kinds.

For Liang Ji, Lu Ding and the others are students of the Manggu Academy, and they can be regarded as 'ground snakes' in the Manggu Black Hole, and they can get more information and information that are difficult for Liang Ji to obtain; Moreover, they also have a better understanding of the various Void Demon Clans in the third-order demon region of the Manggu Black Hole, knowing which Void Demon Clans are easier to hunt, where it is easier to lure the Void Demon Clans to gather into groups, and so on.

Liang Ji cooperated with them, and it was undoubtedly much easier and more convenient to hunt the Void Demon Group in the future.

Moreover, when the two sides cooperate, when hunting demon groups, they can also hunt more Void Demon Clans and harvest more demon pills and demon materials.

As mentioned earlier, this is a matter of mutual benefit.

Therefore, Liang Ji did not hesitate to agree to the request of Lu Ding and others.

At that moment, several people made an appointment to meet in the ancient city of Mang, and determined the cooperation plan.

Subsequently, Lu Ding and others selected the target of the hunt and determined the location to lure the demon group, and Liang Ji's subordinate Juan clan began to hunt the demon group as the main force.

And after the cooperation, the effect is also more obvious. Lu Ding and the others obviously knew more about the Void Demon Clan here.

Through the targets they selected, as well as the means of luring, it often only takes two or three months to lure a Void Demon Group, but Liang Ji used to act alone, but it often took five or six months to successfully attract the Void Demon Group.

Among them, the efficiency is doubled, and the harvest is more than doubled.

The cooperation between the two sides was quite successful, Liang Ji's subordinate scroll clan formed a battle array, helping the Mu Emperor to achieve the great power of 'law, heaven and earth', with part of the fourth-order combat power, enough to suppress the third-order demon group, and cooperate with Lu Ding and others to fight with the scroll clan, each time they can hunt six or seven thousand Void demon clans, and harvest a huge harvest.

Liang Ji was quite satisfied with this, so he gradually retracted his mind and paid more attention to his own cultivation, as well as the development and cultivation of the natal stars.

Liang Ji has purchased a variety of spirit seeds and spirit roots from hunting over the past few years, and has continuously planted them into the natal stars, so that the development of resources such as spirit mines, spirit plants, and spirit beasts in the stars can always keep up with the improvement of the strength of the spirit veins of the stars.

In addition, they continue to purchase inheritances suitable for the development of the Juan Clan, Danfang, blueprints, array diagrams, rune inheritances, etc., as well as the improvement of cultivation spiritual places such as the Arena, the Ten Thousand Poison Cave, and the Valley of Flames, so that they can always keep up with the growth and cultivation needs of the Juan Clan.

Of course, these consumption are only third-order spiritual objects and inheritances, although there are many, the spirit stones consumed are also limited, and they can be settled by the following spirit stones.

In the past few years, Liang Ji has really spent a lot of money on buying materials and treasures in the underworld.

Although the number of materials and treasures used to open up the fifth layer of the underworld and build the 'merit pool' is not large, far less than the number of various spirit species, spirit materials, and inheritances in the stars and scroll clans, but these materials and treasures are all medium and high-level things, the lowest is the fourth order, and the highest even reaches the seventh order, and the number of spirit stones that need to be consumed is naturally not the same, and even often needs to be settled with medium-grade spirit stones or even high-grade spirit stones.

Liang Ji opened up the first four layers of the underworld, and almost consumed a lot of the gains he had gained in the war of the Yinghai Black Hole, and even sold a lot of high-level materials that he had harvested in the 'Human Immortal Palace', so as to complete the opening of the four layers of the underworld.

Even so, the original arrangement of various spirit seeds, spirit roots, inheritances, etc. in the underworld still relied on a few tasks.

And now, Liang Ji is preparing to open up the fifth layer of the underworld, buying all kinds of materials to open up the underworld and building the 'merit pool', and he will use most of the spirit stones he obtained from hunting demons several times before.

However, he finally prepared enough resources and treasures to be needed, and it was not in vain for his consumption.

Now, the Mu Huang is leading the Roll Clan Legion outside, cooperating with Lu Ding and others to hunt the demon group, the efficiency has increased greatly, and the situation has stabilized.

And among the natal stars, under the nine earths, under the four layers of the underworld, and the fifth layer of the underworld has also been born, Liang Ji did not hesitate or delay, and the soul directly traveled out of the body in the natal stars, and went straight to the nine earths, traveling all over the four layers of the underworld.

Finally, entering the fifth layer of the underworld that has been cultivated, the soul stretches out its hand, and the natal magic weapon 'Thirty-three Layers of Heaven and Earth Xuanhuang Linglong Pagoda' flies in, the soul seal is played, and the Xuanhuang light blooms on the pagoda, the Xuanguang opens the sky, the yellow light opens the earth, and one after another the soul seal is played, and it flies down to all parts of the newly opened underworld, completing the opening and evolution of the fifth layer of the underworld.

This is already the fifth time to open up the underworld, all the processes and means are already very familiar, and soon the fifth layer of the underworld has been opened up more than half, Liang Ji will sacrifice a 'divine crystal' fragment, into the newly opened fifth layer of the underworld, as the underworld continues to open up and evolve.

Soon after, a spring was formed in the center of this fifth layer of the underworld, and the bubbling Yin Spring flowed out of it, and with the evolution of the underworld, it quickly expanded, turning into a large Yin Spring Lake and sea in the blink of an eye.

Liang Ji's soul after many years of daily travel and practice, its surface has been covered with a layer of golden light, like golden sunlight, he flew to the center of the Yin Spring Lake and Sea, forming a series of soul seals into the Yin Spring, and some islands quickly rose and towered from it, turning into islands in the lake.

Subsequently, the construction of the palace on the island, the image of the Emperor of the Underworld in the palace, etc., are all things that Liang Ji has done many times before, and there is no difficulty.

In the end, behind this Yin Spring Palace, a pond was opened, and the Yin Spring flowed into it, and Liang Ji's soul was another probing move, and more than a dozen meteors fell above the stars, and after being refined by the dragon soul, they were sent to the fifth layer of the 'Yin Spring Underworld' and fell into the hands of Liang Ji's soul.

Tuxing rune crystals, soul liquid, earth spirit beads, earth-walking lotus seeds, etc., are all treasures needed to open up the 'merit pool', among which there are many fourth-order, and even seventh-order middle and upper-level treasures, and it took Liang Ji a large number of spirit stones and treasures to be able to buy and get together.

At this time, Liang Ji sent these treasures into the 'merit pool' that was opened, and the Dao soul seal was entered, and with the integration and evolution of the underworld and the 'merit pool', the yin spring in the pool gradually turned into the color of earthy yellow, and there were earthy yellow lotus in which it took root, sprouted, and grown.

Seeing that another 'merit pool' was gradually cultivated, Liang Ji's soul was laid with a soul seal, and a stone tablet was erected by the pool, on which the words 'Tude Pool' were engraved.

There is no doubt that this is also a place where the soul is reborn, as long as there is a soul who can cross the yin spring and come here, enter the 'Tude Pool', and be soaked and baptized by the water of the pool, and can turn into the soul of a hero.
