Formation is not an obscure concept, the core of formation refers to a set of systems that operate according to certain rules.

Just like the circulation of blood in the body of living beings, the circulation of the Yuan veins in the body of a cultivator, these things can also be called a formation in a broad sense.

However, in the world of cultivators, a formation refers to a means of making the Yuan Qi flow through a certain law and achieving some effect similar to that of the Yuan Shu. Just like the idea put forward by Xia Li, the vitality of the demons can be linked together through the formation, and then the effect of one plus one equals two can be achieved.

The formation way, although the concept is simple, but to study it deeply, there are many doorways, so that some people can even enter the way with the formation, and finally ascend to the god position and become a formation god.

Although the formation does not belong to the scope of his priesthood, it does not mean that Hao Yan has no understanding of the formation, in his position, tens of thousands of years of life has brought him too much experience, whether it is good or bad, he will more or less dabble in it.

After all, even if he is a fighting god, he has to lead his troops to conquer everywhere in the galaxy, and the formation method is very widely used in a large-scale army!

"Lord Lushan, my master has a good way here, but it may need the participation of the demons of Lanshan Palace!"

"Little boy, but it doesn't hurt to say! If necessary, my Lanshan Hall will cooperate!"

The relics of the ancestors are right in front of him, how can Lu Mengyue not be moved? If there is a need, then even if it is those thorns in the hall who do not obey his orders, Lu Mengyue will use force to coerce them to help!

"I don't know if you know how to play the Lushan Lord?" Xia Li asked directly.

"Formation?" Lu Mengyue thought back: "The classics left by the ancestors seem to have knowledge related to formations, but ......"

However, for two thousand years, Lu Mengyue's vein has only been obsessed with cultivation, and she only fantasizes about being able to reach a certain realm, shatter the boundary wall, and leave this world!

"In short, the master will pass on a formation to you, linking everyone's vitality together! In this way, there is no need for Lushan Lord to work hard for several years alone!"

Xia Li's words really made Lu Mengyue very excited:

"Good! Your Excellency Haoyan is really well-informed!

Lu Mengyue turned to Rhubarb and commanded him:

"Let's help His Excellency Haoyan empty these stones first! Then call everyone in the hall over!

Indeed, even if there is a formation to help, everyone in the formation needs to be able to exert a certain amount of strength, so that the total amount of vitality that can be mobilized in the end can support the blow that breaks through the gate!

"Then we're going to start our own work too!" Hao Yan muttered in the sea of knowledge, and Xia Li returned to Lanshan Hall with Rhubarb by the way-

Get ready to start refining these Lock Element Stones!

At this time, on the square in front of the Lanshan Palace, the Suoyuan stones were densely stacked into a hill, and many carnivorous beasts and demons who did not go down the mountain to help ran out to watch the excitement, and they didn't know where they moved back such a large number of strange stones.

After Hao Yan controlled his body and moved his hands and feet, he emptied a place, preparing to use it as his smelting platform.

"Master, what are you doing here?" Xia Li asked aloud, and he saw Hao Yan release a strange Yuan Technique with one hand, drawing a mysterious formation on the ground around him!

"Thanks to you for reminding me! I forgot! And there is such an opportunistic thing as the formation chart!"

That's right, Hao Yan is sketching a simple formation at this time, this formation can absorb the surrounding vitality and gather in the array, which is called the Quartet Gathering Yuan Array, which is a very basic formation.

However, listening to Hao Yan's yin and yang weird tone, it is obvious that he is not too concerned about things like formations, otherwise he would not have been holding back and not using it after getting along with Xia Li for so long

After all, he is the god of war, not the god of formation, he only thinks that the strength of his body is the real strength, and the formation often has to rely on external forces such as yin and yang, heaven and earth, dragon veins, etc., in his opinion, it is indeed an opportunistic trick.

But for the moment, Xia Li is far from being strong enough to ignore the formation, so at this time, Haoyan is really helpless to use these means of the formation.

"Buzz ——!"

After the outline of the Quartet Gathering Yuan Array was completed, Hao Yan sat in the center of the formation diagram and slightly poured the vitality into the array, and under the rotation of the Yuan Qi, he actually absorbed all the free Yuan Qi around him! This made the concentration of the Yuan Qi in the formation increase suddenly! It almost reached the level of Yuan Qi absorption when he was promoted!

"Are you ready, boy! There are so many stones! It's very tiring to refine!" Hao Yan said in a deep voice: "Since this is different from cultivation, you have to release your vitality all the time, so it will make me tired quickly like a fight, so you only have half an hour! See my refining technique clearly!

"Okay master!" Xia Li immediately lifted his spirits, feeling the slightest change in his body.

"Coaxing ——!!"

A red flame formed in Hao Yan's hand, and the flame of the demon Ye bloomed with warmth and brilliance-

"This is the Red Lotus Fire! The temperature is not high! But it is characterized by a smooth and long fire, and it is easy to control! So use it for the first stage of smelting!"

Xia Li didn't speak, and seriously felt the trajectory of this flame element technique running in his body, so that he could release the same flame later.

"Smack——!

Hao Yan made a move with one hand at this time, and a stone a zhang away was held in his hand, after all, the limit of Xia Li's vitality from the body was more than a zhang away.

"Poof——!

Hao Yan exerted force between his fingers, and the flying flower invisible slash and extremely strong grip broke out in an instant, shattering the stones in his palm into powder, and then holding these dust fragments with a gentle vitality, and slowly moving into the flames!

"Bake ——!"

Although the content is extremely low, these powders also contain lock element ingredients in nature, which are integrated into the flames at this time, and immediately make the flames disordered!

"At this time, you should stabilize the fire as soon as possible! Keep the temperature as uniform as possible! These rough stones have a very low lock element, you should have overcome them a long time ago!"

I saw that the fingers of Haoyan's hand controlling the fire moved slightly, and the abrupt flames were controlled, and the powder of the lock yuan stone was slowly calcined, exuding a strange smell.

After nearly half a burnt incense, Hao Yan extinguished the flame and lifted these powders out with vitality, and at this time, these bluestone powders had been slightly burned out of the black texture of Suoyuan Stone.

In the powder, there are small black crystals condensed, and the whole palm-sized stone is kneaded into powder, but the black crystals burned out are only the size of a few fingernails, Hao Yan picked out those black crystals and began his second stage of smelting!

"Bake ——!"

The orange flame bloomed in his hand—

"Phase 2!
