The tools of the refining furnace and the refining instrument do not need to be as delicate as the alchemy furnace, it just needs not to affect the use.

Lu Yao had just finished transforming the refining furnace, and before it had really evolved from a magic artifact embryo to a magic weapon, it had already been taken out and officially used.

With Lu Yao's current ability, he couldn't really start refining weapons, all he practiced was processing and smelting those materials.

Lu Yao's most important thing at present is to arrange the Seven Star Gathering Spirit Array, and he has already entrusted people to build the foundation of those arrays with modern technology.

He only needed to use jade smelting to extract materials rich in spiritual energy, carve the spirit gathering rune, and make it into the activation energy of the spirit gathering array.

To put it bluntly, this is a low-profile version of the spirit stone, which is temporarily used to replace the role of the spirit stone array.

There are about hundreds of spirit stones Lu Yao now, but these spirit stones are still of great use, and they can't be easily wasted on the Seven Star Manor and the Dolphin Bay Fishing Grounds.

Before finding a new spiritual vein, Lu Yao had to save some use of these spirit stones, and give priority to using them to seal the secret realm of the East China Sea and arrange the island protection array on Fangji Island.

This is also the reason why Lu Yao chose to buy these jade stones with sufficient spiritual energy, that is, he planned to refine these jades, although it was a lot of trouble for him, but it was also the best choice in desperation

Lu Yao sacrificed the lava fire in the center of the earth, and the raging flames began to burn violently in the refining furnace.

With a casual move, he absorbed the many jade mines he had found and scraped in the abandoned mine cave in Kunlun Mountain last time, and put them into the refining furnace in an orderly manner one by one.

Allowing the furious energy of the lava fire in the center of the earth to calcinate all the impurities on the jade mine, the jade mine that was originally invested in dozens of catties was only a few taels in size in the end, and the jade that could be used was only a few taels in size, which shrank dozens of times.

However, this kind of jade still cannot be used directly, and the jade that has been calcined and extracted must be put back into the refining furnace and smelted into pieces of standard-sized spirit stones.

The spirit stone smelted in this way contained only one-third of the spiritual energy contained in the lower-grade spirit stone, but for Lu Yao, it was enough for him to use.

After all, the Seven Stars Spirit Gathering Array arranged by Lu Yao was just an ordinary Spirit Gathering Array, and the purpose was only to gather some spiritual energy, so that the creatures within the scope of the formation could grow better.

Such a low-level version of the spirit stone combined with the low-level version of the Spirit Gathering Array can only create an environment suitable for the survival of living creatures, but it cannot be transformed into a suitable environment for cultivation like the cultivation realm.

Because just relying on the aura gathered by such a low-level version of the Spirit Gathering Array is not enough for cultivators to cultivate.

If you forcibly cultivate within such a range, the aura will soon be absorbed, and if those artificial spirit stones are used too often, it won't take long for the aura to be exhausted and scrapped.

If you just modify the environment to make the creatures in the area of the Spirit Gathering Array grow better, you don't have to worry about the artificial spirit stones being easily scrapped.

First, those animals and plants can't consume much spiritual energy, and secondly, once the Spirit Gathering Array plays a role, after the environment is transformed, there will be mutual promotion, which will only make the environment better and better.

In that way, it will not consume much energy of the spirit stone, but because of the gathered spiritual energy, it will also have a feeding effect on the spirit stone itself, so that a virtuous circle will be formed.

This is also why Lu Yao carved the purpose of the spirit gathering talisman on the artificial spirit stone, that is, so that the spirit gathering talisman in the later stage can absorb the spiritual energy from the spirit gathering array and feed it back to the artificial spirit stone.

This is not to say that the energy of the artificial spirit stone will never run out, it will run out of energy sooner or later, and it will need to be replaced with a new artificial spirit stone at that time.

For Lu Yao, as long as it takes three or five years to replace the artificial spirit stone, it is also a very cost-effective thing.

In about ten minutes or so, Lu Yao could smelt an artificial spirit stone, thanks to the lava fire in the center of the earth, otherwise if he relied on the spirit charcoal, he might not be able to make it.

After working for most of the afternoon, Lu Yao made a total of twenty-one artificial spirit stones, calculated according to the three spirit stones placed in a seven-star pillar, the seven steel pillars were exactly twenty-one, and the spirit stones he refined were enough for him to use for the time being.

Lu Yao stopped the movement in his hand and began to carve the spirit gathering talisman on those artificial spirit stones.

Compared with his alchemy skills, Lu Yao's talisman making ability is much stronger, and it is effortless to portray the spirit gathering talisman.

It only took more than half an hour to speak, and Lu Yao had carved all the twenty-one artificial spirit stones on them to gather spirit talismans, and then waited for these artificial spirit stones to be placed on the seven-star pillar, and the seven-star spirit gathering array could be officially activated.

The Seven Star Steel Pillars had been officially transported to the Seven Star Manor two days ago, and they were buried one by one according to the deep pit built before.

In addition, the construction team also pulled the wires at the seven nodes where the Seven Star Steel Pillars were located, and the huge light bulbs on the top of the steel columns were also installed.

The seven-star steel pillar is seven meters high, two of which are buried deep in the ground, and each steel pillar is set up with three nodes, and each node can be placed with a spirit stone.

When all the nodes are opened, the Spirit Gathering Array can be officially launched. In addition to the Spirit Gathering Array, Lu Yao would also arrange a defensive formation and a trapped formation, combining these Seven Star Arrays into the Little Big Dipper Seven Star Array, which greatly improved the security level of the Seven Star Manor.

Lu Yao decided to start arranging the Little Big Dipper Seven Star Array from the locations of Kaiyang and Yaoguang, because there were few people there, even if there was some movement, it wouldn't cause much trouble.

Lu Yao's trapped array was planned to be arranged in these locations, because in the future, this was the most important place in the Seven Star Manor, and Lu Yao would plant spiritual tea, spiritual grass, spiritual plants, spiritual elixirs and other valuable things here.

The cultivation area is also similar, and these are all important guarantees for whether the Lu family can become a cultivator family in the future.

If it weren't for the fact that Lu Yao hadn't fully learned the art of refining weapons now, and many formation bases couldn't be refined, otherwise he would definitely have completely arranged the entire Little Big Dipper Seven Star Array, including the attack formation, and he would have integrated it.

Taking advantage of the fact that there was still an hour before dinner, Lu Yao took the spirit stone and walked quickly to the location of Kaiyang and Yaoguang located in the west of the tail of the Seven Star Manor, and prevented the artificial spirit stone from entering the node position reserved by the Seven Star Steel Pillar.

After arranging the spirit stones and lighting up the three nodes of the entire steel column, the spirit gathering array located in the Kaiyang position was activated.

Suddenly, within the enveloping range of the entire Spirit Gathering Array, the aura between heaven and earth changed slightly, and a faint aura began to gather from all directions.

It works in a subtle and silent way, so that the entire natural environment changes unconsciously.

This change was very slow, and if it weren't for a cultivator like Lu Yao, he wouldn't have been able to sense it at all.
