"Can the space in this Sumeru boundary stone be expanded?" Xiang Chen looked at the black stone in his hand, and the expression on his face became more and more excited.

"That's right, as long as you find other Sumeru boundary stones, you can expand the space inside, and if there are enough Sumeru boundary stones, you can even form a small world!"

"This is really a good thing, thank you Huolin senior!" Xiang Chen was happy in his heart, and his favor for Huolin Beast also increased a little.

"Okay, I've repaid your affection, it's time to get out of here, just now I used my strength to cut off your contact with the outside world, and the content of our conversation is not heard by anyone except you and me, and no one else can hear it, so you'd better not tell them what's going on, especially the fact that you have the Sumeru Boundary Stone in your hands!"

"I know!" Of course Xiang Chen knew the thoughts of the Fire Lin Beast, the husband was not guilty, and he was guilty, and Xiang Chen also understood this truth. The Sumeru Boundary Stone is rare to see, and the space opened up inside alone is enough to make people's hearts move, not to mention that Xiang Chen also faintly feels that the Sumeru Boundary Stone may be much more useful than what the Fire Lin Beast said.

Airplanes......

As soon as Xiang Chen's words were finished, he felt a fluctuation of spiritual power, and then Xiang Chen heard the voices of other people.

"Xiang Chen, why are you okay?" Jiang Yingxue kept supporting Xiang Chen, and even she didn't know what was going on between Xiang Chen and the Fire Lin Beast.

"The Fire Lin Beast is going to take away the Demon Pill of the Silver Crowned Yin Crown Snake, and as compensation, it has improved the strength of the little dragon!" Xiang Chen didn't explain much, it wasn't that he didn't trust Jiang Yingxue, but sometimes, the more he knew, the more dangerous it became.

"Xiaolong's strength has improved a lot, but we are too weak, there must be a lot of opponents like Tian Burang on the road to heaven, now we have to improve our cultivation!" Lin Teng was slightly relieved when he saw the Fire Lin Beast leaving, the momentum of the Fire Lin Beast was too strong, so that Lin Teng felt unbearable.

Lin Teng is right, although the strength of the Yan Loach can now defeat Tian Burang, but this is not a long-term solution. We must also improve our strength!" Xiang Chen and Lin Teng had similar thoughts, and this time he fought with Tian Burang, which made him understand the truth that there are people outside the world.

Although Tian Burang was powerful, Xiang Chen knew that he was not the most powerful one on the road to heaven. Xiang Chen realized that the opponent in the future will be stronger, and in the second half of the road to heaven, everyone will have more opportunities to contact, and only by improving their own strength can they go further.

"We've also accumulated some resources in our hands, and now that we have a lot of demon beast essence elements at the bottom, we don't have to worry about being pulled too far away by other teams. But I have already found a quiet place to cultivate, and when my strength is improved to the late stage of the Void Tower Realm, or even to the Actual Tower Realm, I will come out to compete with others!" Jiang Yingxue suggested.

"I think what Yingxue said makes sense, we really need to summarize the gains during this time!" Yun Yiyi also agreed to improve her strength first, and then take the back road.

"Then let's think of a quiet place first!" Xiang Chen finished speaking, and already flew towards the outside of the crater.

"It's right here!" Coming out of the crater, Xiang Chen led everyone to walk a distance, and finally found a mountain peak.

There was no need to find a cave to cultivate, Xiang Chen teamed up with Lin Teng, and soon dug a cave from the middle of the mountain.

This time, in order to make everyone more comfortable, Xiang Chen and Lin Teng deliberately increased the space. Just the small cave that has been separated, there are seven or eight zhang in radius, such a large space, not to mention sitting and cultivating, it is not a problem to play fists and feet.

After doing all this, Xiang Chen and the others each entered their own small space.

The spar and pill Xiang Chen had already been allocated to everyone, and now everyone had enough cultivation resources in their hands.

Xiang Chen sat in his small space, and he was not in a hurry to cultivate, he wanted to completely refine that Sumeru boundary stone. In addition, when he was fighting with Tian Burang, he once entered a mysterious realm, and he had a new understanding of many things in cultivation. Of course, Xiang Chen also needed time to replenish the spiritual power he had lost using the Son of Heaven Sword.

The time for cultivation always passed quickly, and in the blink of an eye, Xiang Chen had been sitting in the cave for three days.

In the past three days, Xiang Chen not only cultivated all the spiritual power consumed, but also completely refined the Sumeru Boundary Stone.

The Sumeru Boundary Stone was originally the thing of the Silver-crowned Yin-crowned Snake, and the Silver-crowned Yin-crowned Snake used to be a spirit animal, although many of the things it had accumulated were consumed, but there were still a lot of things left in the space of this Sumeru Boundary Stone.

Among them, there are dozens of elixirs alone, and these elixirs are more than 100 years old, and some are even close to 200 years. The space of the Sumeru boundary stone is completely closed, and the elixir will not lose its effect when placed inside. Therefore, the medicinal effect of these elixirs is still the same as the year when they were first picked.

Xiang Chen withdrew the power of the divine soul from the Sumeru Boundary Stone, this is not the time to count the harvest, and improving the strength is the most important.

Airplanes......

Xiang Chen casually stuffed a few pills into his mouth and closed his eyes again. When he closed his eyes, a wave of spiritual power emanated from his body.

An hour passed, another hour passed, and Xiang Chen never opened his eyes, but the spiritual power fluctuations on his body became stronger and stronger.

Click......

I don't know how long it took, but Xiang Chen felt a soft sound in his body.

Finally, it was time to break through, cultivation needed to be gradual, and after this period of savings, Xiang Chen could finally impact the late stage of the Void Tower Realm.

Click......

The inexplicable clicking sound in Xiang Chen's body became more and more frequent, and as these sounds came out, Xiang Chen's whole body tensed.

Airplanes......

Finally, a strong wave of spiritual power was sent out on Xiang Chen's body, and his aura also changed at this moment.

"In the late stage of the Void Tower Realm, it is really a lot stronger!" Breaking through the late stage of the Void Tower Realm, Xiang Chen felt that his strength had increased a little, but he did not stop his cultivation because of this.

Grunt...... Grunt......

Opening his mouth and swallowing two more pills, Xiang Chen began to stabilize his realm.

Although Xiang Chen was very anxious, he would not rush forward. Rapid improvement in cultivation is something that everyone desires, but that will have a certain negative impact, and of course Xiang Chen will not do such a thing.

Buzz Buzz......

After Xiang Chen broke through, Jiang Yingxue, Lin Teng, Hua Xiaoxiao and Yun Yiyi also heard movement there. Although Xiang Chen closed his eyes, he could also feel that these people should have also broken through to the late stage of the Void Tower Realm.

The path of cultivation is very long, and every time you cross a stage, your strength will improve to varying degrees, even if it is only a small realm, you will have obvious experiences.

Like Xiang Chen, although everyone else also broke through, they didn't stop. The second half of the road to heaven will become more and more dangerous, and now although they have broken through a small realm, they still can't guarantee their safety.

......

Call......

Xiang Chen opened his eyes again, and now he was already a cultivator at the peak of the Void Tower Realm. These days, Xiang Chen's harvest is not small, not only has his cultivation been promoted from the middle stage of the Void Tower Realm to the peak of the Void Tower Realm, but even the Flame Spirit Technique has also been cultivated to the fourth layer.

Ever since he fought with Tian Burang that day, Xiang Chen's Flame Spirit Technique had faintly shown signs of a breakthrough, and it wasn't until this time that he cultivated and improved his cultivation, and his Flame Spirit Technique also improved and entered the fourth layer.

However, at this time, Xiang Chen stopped cultivating. From the virtual tower realm to the real tower realm, it is necessary to continue to accumulate, and Xiang Chen now feels that his accumulation is not enough, so he simply gave up the plan to break through to the real tower realm.

Airplanes......

Xiang Chen's hand flipped over, and a piece of animal skin appeared in his hand.

This animal skin was found by Xiang Chen in the space from the Sumeru Boundary Stone, and what was recorded on this animal skin was a kind of body refining spirit technique, called the Nine Yang Overlord Body Formula.

This Nine Yang Overlord Body Recipe is divided into three stages, each stage has three layers, and you need to find three kinds of Yang Fire Quenching Body, the further back, the higher the requirements for the Yang Fire grade.

Now that the others were still cultivating to stabilize their realm, Xiang Chen didn't want to disturb them. That's why I took out this Jiuyang Hegemony Formula, and I plan to try it.

Cultivating the first two layers of this Nine Yang Overlord Body Technique does not need to quench the body with pure Yang Fire. But it also has to endure a lot of pain.

Xiang Chen's body moved, and he began to cultivate according to the method recorded in the first stage of the Jiuyang Overlord Body Technique.

Xiang Chen felt that his body was constantly stretched and overwhelmed. After a while, my whole body was already soaked with sweat.

After about two hours, Xiang Chen's first layer of cultivation was finally completed, and now a small puddle had formed in his place, which was full of his sweat, but this sweat carried some impurities in his body, exuding a fishy smell.

Call......

Xiang Chen let out a long breath, the Jiuyang Overlord Body Technique was really extraordinary, after cultivating the first layer, he already felt that his whole person had become a lot lighter.

"Then cultivate the second layer!" After cultivating the first layer, Xiang Chen only briefly checked his body and began to cultivate the second layer.

The second layer of cultivating the Nine Yang Overlord Body Technique was even more painful than the first layer. Even Xiang Chen almost couldn't bear it. Fortunately, Xiang Chen's perseverance has been tempered enough during this time.

An Hour...... Two Hours...... Three Hours......

This time, Xiang Chen practiced for five hours before he completed the second layer of cultivation of this Nine Yang Overlord Body Technique.

After cultivating the second layer of the Nine Yang Overlord Body Technique, Xiang Chen felt that his strength had improved a lot. Although it can't be used to defend against the enemy, it can make him last longer in battle.

Buzz Buzz......

At this time, in several other stone chambers, there were four spiritual power fluctuations.

These four spiritual power fluctuations were sent out almost at the same time, and with these four spiritual power fluctuations, Jiang Yingxue, Hua Xiaoxiao, Lin Teng, Yun Yiyi and others also broke through the peak of the Void Tower Realm.

"How are you doing?" Feeling the breath of a few people, Xiang Chen Chong walked out of his stone room.

"It's already the peak of the Void Tower Realm, but it's still very difficult to break through to the Void Tower Realm!" Lin Teng frowned slightly, he felt the opportunity of the Void Tower Realm, but like Xiang Chen, he couldn't break through because of insufficient accumulation.

Jiang Yingxue, Yun Yiyi and Hua Xiaoxiao are in a similar situation.

"It's good now, now that we're meeting Tian Burang, maybe we won't have to be so miserable!" "Now that Xiang Chen's Flame Spirit Technique has been cultivated to the fourth layer, even if he doesn't let Ueda again, he won't be afraid.
