As time goes by, Yang Kai basically maintains the speed of refining a set of seventh-grade resources every six months, and he does not blindly work behind closed doors.

Practice is extremely boring. If the mind and nature are not cultivated enough, it is inevitable that you will become restless and impatient when you maintain this state for a long time.

Although Yang Kai would not have such a situation, he was trying his best to avoid it. Basically, every time he refined a set of seventh-grade resources, he would go out of seclusion and walk around.

As short as three or five days, as long as ten or half a month, relax, soothe his muscles and bones, and then go to seclusion. This combination of work and rest greatly improves his efficiency in practice.

In his spare time, he took the time to go to the Battle Preparation Hall, handed over all the fifth and sixth grade resources in his hands, exchanged them for military achievements, and exchanged all the military achievements for the seventh grade five elements resources.

These fifth-grade and sixth-grade resources were brought from the Three Thousand Worlds. They were originally used for their own practice. Now his best way to practice is to refine seventh-grade resources. These fifth-grade and sixth-grade resources are not of great value to him, and seventh-grade is the best choice.

The exchange of the five elements resources of the seventh grade is beyond imagination.

Basically, if you pay two sets of sixth-grade five-element resources, you can exchange them for one set of seventh-grade ones, with the exchange ratio of two to one.

You should know that in the Three Thousand Worlds, the value of each product is ten times different, but it is only twice as high as that of Biluoguan.

First, if you intend to take care of these soldiers who fought against the Mo tribe, it is naturally impossible to calculate the value of materials of each grade according to the ratio of the 3,000 worlds. Second, the resources of the seventh grade are not consumed much. Over time, the Biluo Pass has accumulated a lot of storage for the seventh grade resources, and even the eighth grade is very rich.

There are quite a few top-grade Kaitians in the pass, and there are as many as dozens of eighth-grade towns alone. However, when they practice, they will not be as luxurious as Yang Kai to refine the resources of the seventh-grade resources. In the final analysis, they are still a rare shortage of high-grade Yin and Yang. There are no seventh-grade and eighth-grade Yin and Yang resources. Even if there are more resources of the five elements, they dare not refine them at will, so as not to cause the imbalance of their own small universe power.

Now outside Biluo Pass, with the mining of those Qiankun worlds, more seventh and eighth grade resources have been discovered, but these resources will be consumed as refining weapons and setting up formations, rather than being used for practice.

In this way, Yang Kai took a big advantage.

The resources he has were completely enough for him to be promoted to the eighth grade and even had some savings.

He also took the time to go there with Dantang, wanting to know how the Mo Di Dan was. Unfortunately, he failed to meet the two masters Zhuge Ming and Zhou Fang, and only saw Tang Jian.

According to Tang Han, since Yang Kai left that day, the two masters have been carefully deducing the complete pill recipe for experimenting with the Mo Dan. Now they have consumed countless medicinal materials, and they have finally gotten a little surprised.

However, if you want to get the Mo Di Dan out, you probably need to work hard. In the medicine garden, the Wu Guangcao and the Qingyu Xuan Vine are already increasing their intensity. Once the Mo Di Dan really appears, it will definitely meet the needs of the alchemy.

On this day, Yang Kai refined a set of seventh-grade resources again and walked out of the secret room.

But seeing Feng Ying was already waiting outside the door. When he heard the sound of opening the door, Feng Ying turned his head and looked at it, smiling slightly: "My junior brother's practice is indeed very regular."

In the past two years, Yang Kai has come out of seclusion every six months, and Feng Ying also calculated that he may come out of seclusion recently, so he will wait here.

"Cultivation is boring, come out to relax." Yang Kai stretched out his muscles and bones, "Is there anything that senior sister?"

Feng Ying was waiting here specifically, and it was obvious that he had something to look for her.

"Uncle Zhong Liang has an order to ask you to see him immediately after you leave the customs." Feng Ying's expression was solemn.

Yang Kai also corrected his face: "What happened inside the pass recently?"

Feng Ying shook his head and said, "There is nothing in the pass, and the words revealed by the uncle are related to the Tiandiquan."

Yang Kai immediately understood.

After he refined and fused the World Tree, he told the four legion commanders of Biluo Pass that he would like to give up the Heaven and Earth Spring in his own small universe. After all, the World Tree also has the effect of sealing the Small Heaven and Earth Spring, and it is not bad at all compared to the Heaven and Earth Spring. Although it has not been verified, Yang Kai felt that even if there is no Heaven and Earth Spring, the power of ink could not erode himself.

At that time, Zhong Liang and others said that this matter was not urgent. After all, even if he was willing to sacrifice the world and spring, who would take over this thing, they would have to discuss it carefully.

Yang Kai didn't expect that it would take two years to wait. It seemed that the legion commanders were extremely cautious in this matter.

"I'll go here." Yang Kai said, soared into the sky and headed straight for the Western Army Office.

When I arrived at the place, I asked someone to inform me and waited for a while before I could call Zhong Liang.

When he walked into the hall, he saw Zhong Liang explaining some matters to a seventh-grade rank. After he had finished handling the matter, the seventh-grade rank retreated, Yang Kai took a step forward and clasped his fists and said, "I've seen an adult!"

Zhong Liang nodded slightly, stood up and said, "What's wrong with calling you here? Did Feng Ying tell you?"

Yang Kai nodded and said, "Senior Sister has already said that you have already confirmed the candidate to take over?"

Zhong Liang said: "It's certain, but before this, I have to remind you that since you want to give up the Tiandi Spring, you will inevitably give up part of your own small universe. At that time, the small universe will be damaged. Although the Xuanpin Spirit Fruit can be repaired, it is not a big deal. However, if you lose the ability to resist the erosion of the power of ink, you must stay in the pass honestly in the future and not run around."

Yang Kai said respectfully: "Of course I know this."

Zhong Liang looked at him, with a soft look on his face and praised: "You have the heart."

No one knows what the World Tree Sect Tree has, except Yang Kai. Even if he doesn't sacrifice the World Tree Sect Tree, no one will say anything. But after he merged the World Tree Sect Tree that day, he immediately proposed this matter, which shows that he is also a person who is grateful for his kindness. An eighth-grade Kaitian with the four pillars of the universe can definitely exert a much better power on the battlefield. After all, he no longer needs to distract his mind to resist the omnipresent erosion of the power of ink.

"Follow me." Zhong Liang waved and walked out of the hall first.

Yang Kai took a step to keep up.

Soon, the two of them left Biluo Pass and came to the outer void.

And somewhere in the void, a figure stood tall, obviously having received Zhong Liang's message, waiting here.

Yang Kai recognized who the figure was at a glance, and suddenly realized: "It was Lord Ding Yao who took over the Tiandiquan?"

The figure waiting here was Ding Yao, the commander of the Eastern Army.

Zhong Liang nodded: "Yes, under the ancestors in Guanwei, this old guy is the strongest, so it's best for him to take over."

Yang Kai twitched his lips. Zhong Liang dared to call him old man Ding Yao, but he could not disrespect him.

But such a situation is expected.

There are not many four pillars of Qiankun on the human race, but there are still some, without exception, all of them are in the hands of the eighth-grade Kaitian.

The ninth-grade ancestor does not need the four pillars of Qiankun. They are extremely powerful and have a deep cultivation level, so they don’t have to worry about being eroded by the power of ink. Even if the seventh-grade Kaitian has a Tiandiquan, it may not be able to be kept. This is also the reason why Zhong Liang tried his best to resist Yang Kai’s expedition to fight. Yang Kai had too much ties and was not strong enough. If something unexpected happened, he would not be able to explain to the ancestor.

Nothing is needed for the ninth grade, but not enough strength in the seventh grade, and it is best to take over the eighth grade.

Yang Kai thought that the one who took over Tiandiquan would definitely be one of the four legion commanders, but now it seems that this is true.

When he got closer, Ding Yao looked at Yang Kai and asked, "If you open the bow, you will not turn back. You still have time to regret it now."

Yang Kai grinned and said, "Since the decision has been made, there is no reason to change it."

Ding Yao nodded slightly: "Then I won't advise you."

Zhong Liang said: "If you are ready, start, but Yang Kai will try to minimize his own losses."

"I understand." Yang Kai nodded and closed his eyes.

As the divine thoughts surged, the power of heaven and earth was turbulent, and the small universe was buzzing. The originally complete small universe suddenly shook under his own independent use, and then a burst of heaven and earth collapsed.

Yang Kai instantly glared! A low roar like a beast roar came from his throat.

The pain that was tearing apart made him tremble involuntarily.

Yang Kai never knew that it would be so painful to give up his own little universe. Before he brought the light of purification, on the battlefield of the two tribes, a soldier of an individual tribe had to give up his own little universe. While enduring this pain, he also had to fight the Mo tribe to death. What a cruel experience.

It is not difficult to give up one's own small universe, it is just a matter of abandoning part of the small universe. The difficulty is that Yang Kai needs to suppress the breath of Tiandiquan in this territory.

Although he tried his best, the small universe he finally gave up was still quite a territory.

When the portal of Xiao Qiankun opened, a territory of more than ten acres in size appeared in the void. At the center of the territory, a clear spring was particularly eye-catching.

When this territory appeared, the surrounding void seemed to have solidified due to the power of the Tiandiquan sealing.

Ding Yao was waiting for the moment, and reached out to capture the territory that was cut off. When the great power of heaven and earth surged, the territory disappeared instantly and was taken into his body.

The next moment, both Yang Kai and Ding Yao quickly sat cross-legged.

Zhong Liang hurriedly handed Yang Kai a Xuanpin Spirit Fruit that had been prepared long ago: "I'll accept this fruit soon."

Although taking it for a while will not have any effect, he is still afraid that Yang Kaigenji will be damaged as a result.

The pain on Yang Kai's face was obvious, and his forehead was covered with cold sweat. He reached out to take the Xuanpin Spirit Fruit handed over by Zhong Liang. When he was about to take it, he suddenly frowned and frozen it.

Seeing this, Zhong Liang was very worried: "What's wrong? Is there anything wrong?"

Yang Kai shook his head slowly, and did not answer immediately, but immersed himself in his mind and investigated his own small world.
