Half an hour later, all the world fruits have been picked.

Although the fruit is picked cleanly, the subtree of the world tree in front of you is also of great value, so you can't miss it.

However, Cha Hu did not immediately add the world fruit to Xiao Qiankun. After pondering for a long time, he said: "Yang Kai, I have collected this world tree."

Yang Kai was stunned.

Cha Hu said: "Although I don't know what benefits will be for this thing to be collected, it is not only a subtree of the world tree, but also planted by ancient powerful people in their own small world. It must be harmless. Although you are only in the seventh grade now, it has a great relationship and cannot tolerate any mistakes. It would be fine if you have no benefits to this thing. If there is any benefit, it will also facilitate you to grow faster and have stronger self-protection power above this battlefield of ink."

Yang Kaixin felt grateful and clasped his fists and said, "Thank you, sir."

Cha Hu waved his hand: "You have discovered the eleven secret realms here. If you were not for you, I would not have gained so much. This physics should be collected by you. However, I will first tell you that even if you have asked you to collect this item, there will be no objection in the pass, but this item needs to be exchanged for military merits. As for how much military merits you need, it depends on how much benefits you can get after collecting this item. When you go back to the pass, several legion commanders will ask about this matter."

Yang Kai nodded: "It should be."

Although he discovered everything in this secret realm, in this battlefield of Mo, any gains need to be handed over and exchanged with military achievements. This is the rule.

"You can do it yourself, I'll go there and take a look." Cha Hu said, and then headed to the medicine garden. Most of the medicinal materials in the medicine garden had been collected, but there were still some unknown people left and left. Everyone dared not pick them at will, so as not to damage the medicinal properties.

Standing in front of the subtree of the World Tree, Yang Kai's divine thoughts surged, the laws of space were ups and downs, and the void where he was in became slightly distorted.

He thought that with his current strength, it would be fine to move the subtree of this world tree into the small world.

But after he carefully checked, he realized that he was thinking too simple.

Another hour later, when Chahu picked all the remaining medicinal materials in the medicine garden, he found that Yang Kai had been standing in front of the subtree of the world tree and had never taken action. Not only that, even Yang Kai's face was slightly pale, which was obviously not easy to consume.

Cha Hu frowned, flashed to him, and waited quietly.

Another hour passed, Yang Kai suddenly opened his eyes and let out a slight breath.

"What's going on?" Cha Hu asked, and Bai Yi also looked at Yang Kai curiously.

Yang Kai smiled bitterly: "Sir, the subtree of this world tree is closely connected with this entire secret realm and is inseparable."

Cha Hu was surprised: "What happened?"

While speaking, he was immersed in his mind and sensed it. His strength and cultivation were far superior to Yang Kai, so he quickly found out that the situation was indeed as Yang Kai said. The aura of the subtree of this world tree was firmly connected with the secret realm, and was integrated with each other, and was inseparable.

This was something he never thought. He asked Yang Kai to collect the World Tree before, which was for Yang Kai to consider it. As he said, although he didn't know what benefits he would get from collecting the World Tree, there was definitely nothing bad. If there was really good, Yang Kai could benefit from it and grow rapidly.

Although the cultivation level of the seventh-grade Kaitian is good, it is still too thin when facing the domain master. If the king is targeted again, it will not even have the power to protect itself.

Cha Hu also hopes that Yang Kai can upgrade his cultivation to the eighth level as soon as possible so that he can make more contributions to the human race.

However, now this world tree is closely connected to the entire secret realm. Not to mention Yang Kai, even his eighth-grade town cannot easily collect the world tree.

"What a pity!" Cha Hu sighed slightly.

Yang Kai frowned and said, "Actually, it's not impossible to charge, it just takes some time."

Cha Hu was puzzled at first, but soon understood what he meant: "This method is not possible, don't even think about it."

"Sir, I know what I'm talking about?"

Cha Hu snorted coldly: "This object is closely connected to the entire secret realm. If you want to collect this object, you must enter the entire secret realm into the small universe."

"That's true!" Yang Kai nodded, "There is no other way."

Cha Hu said in a deep voice: "But in this way, the various Taoist marks contained in this secret realm will be integrated into your small universe. It would be fine if the many Taoist marks match your small universe, and it might also enhance your strength, but if they don't match, it will be an impurity for you, which is very likely to affect your foundation. You must know that this method is equivalent to those evil demons and heretics forcibly refining the great power of the world in the universe in order to improve their strength."

This secret realm is fundamentally a small universe left by the human power in ancient times. It contains the crystallization of the human power's lifelong practice. The various Taoist traces hidden in the secret realm are not all beneficial to Yang Kai, and they are very likely to be of great harm to him. It is precisely because of this that Cha Hu strongly opposed it. He asked Yang Kai to collect the subtree of the World Tree because he was thinking about him, but how could he sit back and see him break his foundation?

Yang Kai nodded and said, "I know this naturally, but sir, don't forget that the disciple is carrying the spring of heaven and earth, and the small universe is round and flawless, and it is not invaded by external forces. The disciple only needs to spend some time to drive away the great power of heaven and earth and many traces of the Tao in this secret realm. At that time, the subtree of this world tree will naturally be left."

Yang Kai had such experience. When he led many sixth-grade Kaitian in the void land, he was chasing Zuo Quanhui in the new great realm, Zuo Quanhui spread his own small universe at the end of his journey and resisted desperately. In that battle, Yang Kai also spread his own small universe. Although he killed Zuo Quanhui, the collision and integration of each other made Yang Kai's small universe add a lot of power belonging to Zuo Quanhui, and those forces are impurities.

Later, Yang Kai also spent some effort to remove these impurities, which did not affect his own foundation.

At that time, he had no Tiandi Spring, and now he had Tiandi Spring, so naturally he didn't have to worry.

Chahu hesitated immediately.

Yang Kai struck the railway while it was hot: "Sir, even the power of ink cannot erode the disciple's small universe, why should you be afraid of the power of the secret realm here? It can be said that the disciple is the best candidate to collect this thing."

Cha Hu's expression finally loosened: "But in this case, it will take you quite a while. If there is no benefit at that time, wouldn't it be more worth the loss?"

Yang Kai smiled and said, "It's always okay to try it. Even if there is no benefit at that time, the disciples can get a subtree of the world tree and raise it in the small world. Perhaps in a few years, the world fruit will be produced. What's more, this is a subtree of the world tree after all. If it can be harvested, how can it be without benefits?"

Cha Hu said silently and said for a while: "Okay, as you said, I will protect you. If there is any abnormality, you need to give up immediately."

"Thank you, sir." Yang Kai clasped his fists.

Since we have decided to add this entire secret realm to the small universe, there is no need to explore again. Under Cha Hu's order, all unrelated people have withdrawn from this secret realm.

Soon, only Yang Kai and Cha Hu were left in the secret realm.

Yang Kai took a deep breath, activated his own small world and spread it down.

The next moment, the territory of its own small universe spread like light and lightning, and quickly covered the surroundings.

Chahu stood tall in the void, watching intently, and couldn't help but raise his eyebrows.

Logically speaking, Yang Kai is a new seventh rank, and his foundation will not be too stable. However, under his observation, Yang Kai showed no sign of unstable foundation. Instead, his foundation is rich. Moreover, with the expansion of Xiao Qiankun, he saw all kinds of creatures living in Xiao Qiankun, and there was a clear spring, and the clear air penetrated the world.

When his place was covered by Yang Kai's small universe, he even felt a little dazed. At that moment, it seemed that even his own perception was affected.

The law of time? Chahu browed.

Everyone knows that Yang Kai has extremely high attainments in the way of space, but he never knows that he has such cultivation in the way of time.

Cha Hu was secretly shocked. How did this kid practice and was able to master the way of space and time at the same time. You should know that either of these two great ways is difficult to get started, let alone master it. Those who can walk one way on these two great ways are favored by heaven. It is incredible that both great ways have such attainments.

As his mood was rising and falling, Yang Kai's little universe had already enveloped the entire secret realm and showed no discomfort, which made Cha Hu slightly relieved.

Suddenly, Yang Kai looked up at him: "Please step back for now!"

Cha Hu nodded slightly, his body turned into a stream of light, and rushed towards the other side of the portal.

When Yang Kai and Xiao Qiankun were spreading, there was no problem with him in it, but now that Yang Kai wanted to take back Xiao Qiankun, he couldn't continue to stay. After all, his cultivation level was one level higher than Yang Kai, and Yang Kai and Xiao Qiankun's size was not enough to contain him.

When I left the portal, I turned my head and looked back. I saw a trembling feeling quickly heard from the portal. Sometimes there was a buzzing sound, and the portal location became even more distorted, as if it might collapse at any time.

This situation lasted for several days. At some point in a few days, the door disappeared, and a figure suddenly appeared there, and it was Yang Kai.

But at this moment, Yang Kai's face was pale and his breath was even more volatile, as if he had suffered a severe blow.

Bai Yi approached the past immediately, and Yang Kai waved his hand to signal that he was fine.

His current state is just because he forcibly included the secret realm in his own small universe. The secret realm is also the small universe left by the ancients. Forcibly containing it will inevitably have a huge impact on him, but if he wants to get the world tree, he must be so.
