Fang Yun returned home for a while, and Ye Lao also returned, and at the same time, the subordinates carried in several boxes of energy crystals.

Fang Yun's heart was full of joy when he saw it, so many energy crystals were enough for him to arrange dozens of middle and low-level formations, but he didn't expect that he would keep a low profile for two or three years, and the first time he ate black, he would gain a lot of money.

As for the results of the Black Wolf and the others, Fang Yun didn't have the obligation to care about them, even if Ye Lao didn't kill them, most of them would not make them feel better.

"Yun Shao, I brought back all the energy crystals in that shop. ”

Although this is considered a robbery, but Ye Lao and Fang Yun didn't care about it at all, the shopkeeper and the black wolf are not good people, I don't know how many people in Yancheng have been persecuted by them, now that Fang Yun has eradicated the hegemony of Yancheng, it is too late for them to be happy, so naturally they will not be sad for the black wolf.

"Well, with these energy crystals, it's enough to make your Dou Qi break through in the shortest possible time. Fang Yun said.

"Then what should I do next?" Ye Lao was also looking forward to it, since Fang Yun was so sure, he was naturally full of confidence in Fang Yun.

"Don't be so anxious, I'll prepare first, and you'll come back in the evening. Fang Yun said.

Fang Yun first had to arrange a Na Yuan Array, the role of the Na Yuan Array was very similar to that of the Spirit Gathering Array, the difference was that the Na Yuan Array could gather very strong spiritual energy in the shortest possible time.

The Spirit Gathering Array was unable to gather such a rich aura, but the advantage of the Spirit Gathering Array was that its staying power was far from being comparable to that of the Nayuan Array.

The Spirit Gathering Array that Fang Yun had arranged two years ago had not failed until now, according to Fang Yun's estimates, this Spirit Gathering Array could still operate for at least twenty years, while the Na Yuan Array could only support three or five days before it would lose its effect.

And these energy crystals that Fang Yun found were used to maintain the operation of the formation, the energy in the energy crystals was extremely pure energy, and they were used for many purposes, and the people in this world were mostly used for cultivation, or for alchemy, alchemy, and magic arrays, all of which used energy crystals.

Fang Yun discovered that the energy crystal could also replace the immortal qi and be used to arrange the formation.

This discovery saved Fang Yun a lot of effort, when he first arranged the Spirit Gathering Array, Fang Yun was not yet three years old, and his cultivation at that time was not even in the middle of Qi Gathering, arranging a Spirit Gathering Array almost drained his immortal qi, and he couldn't ease his breath for a few days.

At that time, the family almost thought that Fang Yun had some kind of illness, Fang Yun was already lazy, if it wasn't for the convenience of cultivation in the future, he would naturally not be willing to go through the trouble of arranging the formation.

However, now that these energy crystals are replaced, it will save a lot of effort, at least it will not be as tired as it was a few years ago.

The upper and intermediate formations of the Nayuan Formation, if the formation was normally arranged, Fang Yun would have to exhaust the immortal power before he could complete the arrangement of the formation.

However, now that there are energy crystals, the speed of Fang Yun's arrangement is obviously much faster, but the energy crystals are also like flowing water, and a medium-grade energy crystal will be consumed in a moment, if it is a high-grade energy crystal, it will be able to support it for a while.

If the shopkeeper saw it, it was estimated that his heart would be dripping blood, Fang Yun spent a full three hours to finally arrange the Nayuan array, but next to the formation, there was already a pile of dim and dull energy crystals.

The energy crystals that need to be consumed to arrange the Nayuan Array are much more than Fang Yun expected, Fang Yun is secretly glad that he has grabbed so many energy crystals today, otherwise he would have to consume a lot of immortal qi to complete the Nayuan Array.

The reason why Fang Yun chose the night was not chosen at random, the aura at night was more abundant than during the day, and the effect of the Nayuan Array would also be greatly improved.

A moment later, Ye Lao had already returned to Fang Yun's small courtyard, Fang Yun had been waiting for a long time, and when he saw Ye Lao coming, he immediately beckoned Ye Lao to sit in the center of the array.

"Ye Lao, wait a minute, you just run the mantra and incorporate the surrounding energy into your body, and you can absorb these energies boldly without scruples. Fang Yun said.

Ye Lao nodded, sat cross-legged, and began to run the mantra, this mantra Ye Lao had already memorized, and he knew it well, and under Fang Yun's guidance, he had a deeper understanding of the mantra.

Now that it is running, it is more and more proficient, and the touch of the aura is also countless times sharper than before, although the old man has cultivated the fighting qi for a lifetime, but the fighting qi is not absorbing the aura of heaven and earth, but the energy from the body, so the understanding of the aura is not intuitive.

However, with the deepening of the mantra and Fang Yun's explanation, Ye Lao began to slowly become familiar with the endless energy around him.

He also understood that the aura of heaven and earth was not different from the fighting qi in his body, but the mantra that Fang Yun taught him could absorb these energies into his body, and after tempering, a part of it would be transformed into pure fighting qi and remain in his body.

This is like opening another door for him, allowing him to have a deeper understanding of his own fighting spirit and energy.

To the surprise of Ye Lao, the energy around him seemed to be many times richer than before.

If the ordinary aura is like a mist, floating in the air, then at this moment he is like drowning in a pool of water, and the aura around him is unimaginably rich.

And the rich aura, with the operation of the mantra, like a turbulent wave, surged into the body of the night elder, and the night old man didn't even have time to run the mantra, and the entire body inside and outside was completely invaded by the rich aura.

Ye Lao felt that his body was swollen, this was like a person who was full of food and support, but he was still stuffing Ye Lao's body, and Ye Lao had no time to 'digest' these aura.

Even if he stopped talking at this moment, the aura would still pour into his body in an endless stream.

Fang Yun watched from the sidelines, observing Ye Lao, observing the surrounding aura, as well as the changes in the fighting qi in Ye Lao's body.

After a while, Ye Lao finally couldn't bear it anymore, with a trace of pain on his face, and shouted in a low voice: "Yun Shao, I can't help it......"

In fact, this is not real pain, although the aura cannot be directly absorbed by people, but absorbing some will also make people feel comfortable, if you absorb more, you will feel bloated, but like Ye Lao, excessive absorption of aura, will naturally react like this.

Seeing that Ye Lao had reached his limit, Fang Yun immediately interrupted the operation of the Nayuan Array, and said at the same time: "Now immediately transform all the spiritual energy in the body into Dou Qi. ”

Fang Yun just wanted to use this stuffing method to make Ye Lao's fighting spirit reach the critical point in the shortest possible time.

This way has a fight with some black-hearted farmers on the earth, of course, Fang Yun has no malicious intentions, he just wants to see the breakthrough of the level of fighting spirit of Ye Lao, this process and changes.

If it is a normal breakthrough, it may take a year and a half, or even longer, to break through the existing level.

Moreover, when breaking through, it requires a lot of energy, and many people will choose to use energy crystals, and at the level of Ye Lao, the energy crystals to be consumed to break through a product are simply astronomical, and even the Fang family is difficult to bear.

Therefore, when Ye Lao breaks through, it is likely to fail, and then it will take several years to accumulate fighting spirit and use it to break through, and many people often use more than ten years or even longer to break through at one time.

Although Ye Lao said before that he could break through in just half a year, he just said that he could try to break through, which did not mean that he could successfully break through.

Ye Lao used several times the usual speed to continuously refine the spiritual energy and transform it into his own fighting qi, and the skyrocketing speed of this fighting qi was like a huge pool, constantly pouring water into it.

Soon, Ye Lao's dantian had been completely infused with fighting energy, Ye Lao's face was ruddy, and his body trembled slightly.

Fang Yun's immortal qi was in Ye Lao's body, he had been observing the changes in Ye Lao's fighting qi, and after he found that Ye Lao's fighting qi had completely occupied the dantian, he opened the formation again.

"Ye Lao, you can make a breakthrough now, and I will help you guide the follow-up energy into your body without your distraction. Fang Yun said.
