After entering the mountainous area, although the terrain is rugged and steep, the number of demonic beasts encountered gradually increased. At the beginning, Tian Xu and Ziyan were happy to fill up the vacant space rings, and the demonic beasts they encountered were swept away by them. It can be that when they arrived at Daba Mountain in northern Sichuan, they found that a large number of demonic beasts had gathered at the northern foot of Daba Mountain, and the nine spatial rings in the hands of the two of them were quickly filled with seven, including many fourth- and fifth-level demonic beasts.

"Something must be wrong, otherwise there wouldn't be so many demonic beasts gathered here. Tian Xu said.

"Is it that the Demon Sect is going to attack some cultivation sect?" Ziyan said, "But there don't seem to be any big sects here." Shushan Jianmen has long since declined, and it should be in western Sichuan instead of northern Sichuan, and Shennong Valley is in eastern Sichuan, and it is not here. ”

After flying for a while, Tian Xu suddenly thought of a possibility: "Could it be that these demonic beasts want to enter Sichuan, but they are blocked here by some formation or something, just like the demonic beasts were blocked by the formation in the Tianshan Mountains half a year ago?"

Thinking of this, Tian Xu and Ziyan no longer moved along Daba Mountain, but turned around and went south, exploring the past in the direction of the Sichuan Mansion Country in the Sichuan Basin.

After reaching the highest watershed in Daba Mountain, Tian Xu's guess was confirmed. The demonic beasts were all concentrated on the north side of the mountain, and none of the demonic beasts were able to cross the watershed and reach the southern foot of Daba Mountain. A coercion stretched into the distance along the watershed, isolating a large number of demonic beasts and guarding the entire Sichuan Basin.

When the two of them reached the ridge, they happened to see a team of five King Kong boars and two whirlwind argali, led by a red-maned giant wolf, attacking this formation. They didn't use spells, but used brute force, and rushed side by side towards the large array, and were immediately bounced back by the large array. After an impact, the seven-scalped and thick-skinned demonic beast fell to the ground like a lightning strike, and the big array was also knocked to tremble.

Along the way, Ziyan was hugged by Tian Xu in the posture of a princess on her chest, in addition to her hands, Tian Xu also attached a formation under her body, making her lie very comfortable.

At this time, Ziyan, who had already recuperated all the way, saw these fourth- and fifth-level demonic beasts, and immediately came to the spirit, jumped up from Tian Xu's hand, and swung his sword to kill them. Tian Xu was so anxious that he shouted from behind: "Be careful, don't cut it all down, this is all good things!"

The red-maned giant wolf led by him did not panic when he saw Tian Xu and Ziyan, in addition to the seven-headed demonic beasts that had just attacked the formation and lost their combat effectiveness for a while, there were also ten fourth-level demonic beasts behind it that were ready to serve as the second echelon, and these demonic beasts were simply a piece of cake to deal with the two Ning Dan Realm cultivators.

It's just that it never thought that just the purple smoke of the third order of Ning Dan would be so powerful in combat power, just a sword, it shattered the sound attack it emitted, and successfully forced it to resist with its teeth, and was cut to the corner of the mouth bleeding. And Ziyan's subsequent second sword actually managed to avoid its teeth, and opened a bloody hole in the weak spot behind its ear, and it just wanted to escape, but Tian Xu, who had not moved, came to it like lightning, grabbed its nose, and it fell down and never woke up.

As for the other fourth-level demonic beasts, before they could react, they were rushed into the beast group by the purple smoke, one person and one sword, and they simply settled the account neatly. The seven unlucky eggs who fell to the ground were even put into the vitality bag alive by Tian Xu, ready to be used as food for the dragon sparrow.

The battle ended in the blink of an eye, and a group of demonic beasts were instantly killed by the two of them, making some of the low-level demonic beasts around them shocked by the powerful and somewhat exaggerated combat power of the two, and immediately dispersed. Tian Xu didn't have the heart to chase them, but a few demonic beasts were so frightened that they ran in the direction of Tian Xu. For these guys who came to the door by themselves, Tian Xu honestly and unceremoniously put them away.

Just when Tian Xu and Ziyan were busy cleaning up the demonic beasts, Yin Yang Ding suddenly said, "It seems to be the breath of the Great Emperor." "The emperor in the mouth of Yin Yang Ding is the Emperor Shennong, not several other emperors.

Tian Xu didn't pay attention to it originally, but when he heard Yin Yang Dingyi say it at this time, he also had a similar feeling. He has been in contact with the four major artifacts of Emperor Shennong these days, and a lot of knowledge about Emperor Shennong, and has a very cordial feeling for Emperor Shennong, and this great array guarding the Sichuan Basin reveals the breath of Emperor Shennong that makes him feel cordial.

Tian Xu said: "Yes, it should be the breath of Emperor Shennong, it seems that this formation should be set up by Emperor Shennong." Except for the Great Emperor, there are probably not many people who can set up such a large-scale formation. ”

Yin Yang Ding said: "The Great Emperor is not good at formations, and setting up such a guardian formation is not the Great Emperor's style of acting. Maybe someone else set it up. Such a formation does not have to be set up by the Great Emperor, below the Great Emperor, there are many cultivation powers who have the ability to set it. ”

What the specific facts are, it is estimated that it is impossible to guess, Tian Xu and Yin Yang Ding sighed for a while, and they will not delve into it anymore.

Now that he saw the big array and confirmed Tian Xu's conjecture, he didn't plan to stay here for long, and continued to fly east along the ridge of Daba Mountain.

In front of the guardian array built along the mountain, many demonic beasts gathered. Tian Xu had no intention of cleaning up these rags, turning a blind eye to the low-level demonic beasts, and only picked the fourth-level or above demonic beasts or those with special functions to kill, and swept away the high-level demonic beasts gathered in front of the formation, leaving only some low-level demonic beasts.

It's not that he doesn't want to put away the low-level demonic beasts, but considering the capacity of the space ring, he can only reluctantly cut his love and choose more valuable demonic beasts to hunt.

Even so, Tian Xu and Ziyan's space rings were quickly filled, but the surrounding demonic beasts did not decrease, and they could only continue to hurry in this "happy trouble".

After walking for a while, Dan Ling suddenly asked, "Master, why did you want to discard those low-level demonic beasts? ”

Tian Xu said helplessly: "I can't let go of the space ring, so I can only pick a more valuable belt." At this time, he suddenly reacted, Dan Ling is connected with his own heart, how could he not understand the reason why he doesn't want low-level demonic beasts? This guy did it on purpose! His mind swept from Dan Ling, and he immediately understood his thoughts.

Dan Ling has been living in Tian Xu's spiritual realm, and is also responsible for the operation of the realm, although his understanding of the realm is shared with Tian Xu, but he is always one step faster than Tian Xu. The solution he discovered was very simple, which was to store these magical beasts in the domain space.

The domain space is a spiritual space, and Tian Xu has always regarded it as a virtual space, but he didn't expect that since he can decide the space rules of the domain space, of course, he can turn the virtual into reality and put real items in it and carry it with him.

Previously, after discovering the role of the domain, Tian Xu had already been able to use the domain to throw stones or pull weeds, and today he also used the domain to fight against the Great Elder. Since the realm can manipulate the objects inside, of course, he can store things by changing the rules of the space in them, so that he can put a large number of demonic beasts in it without worrying about the lack of space.

Tian Xu's domain space is now more than twenty meters in diameter, and since he has just obtained part of the Great Elder's body, especially the soul spear that was shattered by Dan Ling, as well as those golden blood, it is of great help to improve Tian Xu's spiritual power. Just this way, Dan Ling has already absorbed these to seventy-seven eighty-eight, and on this basis, Dan Ling is preparing to further expand Tian Xu's domain. With such a large domain space, there must be a lot of demonic beasts that can be stored. You must know that even if it is no longer expanded, the current domain space is much larger than those space rings in his hand combined.

Hearing this good news, Tian Xu experimented at the first time. His flying body was fast, he circled far away, passing through a group of fleeing demonic beasts, where the domain space was swept, the demonic beasts had disappeared, and he didn't even need to use his hands, completely using the ability of the domain space to get rid of these low-level demonic beasts. These demonic beasts were not killed, but were locked alive by him in small spaces in the realm, and they would be dealt with when they returned. Whether it's used as food for pets or left for Medicine King Dou to replenish his vitality, a living monster is more valuable than a dead one.

Under Tian Xu's unscrupulous sweep, the surrounding demonic beasts were quickly cleaned up, and after walking out of dozens of kilometers, Tian Xu's domain space was already a little more than half full. After continuously applying mental power to control the domain operation, Tian Xu felt mentally tired, and after so many demonic beasts were installed in his domain space, the sensitivity of the operation began to decline, which meant that he couldn't install more.

Tian Xu stopped collecting demonic beasts with some regret, and flew slowly with Ziyan to recover his mental fatigue.

Dan Ling, who had taken back control of the realm, took over the control of the realm and began to expand the scope of the realm using the energy he had just obtained from the Great Elder.

The expansion of the field is not going at a uniform pace as most people think, but it is getting slower and slower. There's no way around it. After all, doubling the diameter would expand the space volume by eight times, and the spiritual power that would need to be consumed would be eight times more. Dan Ling's round of expansion expanded Tian Xu's domain space from about twenty-two meters at the beginning to twenty-seven meters, which was already a very remarkable achievement, and Tian Xu could clearly feel that the domain space was much larger than before.

Since they didn't want to catch demonic beasts anymore, Tian Xu and Ziyan deviated slightly from their original routes, away from the range of the edge of the big array, and away from the gathering area of demonic beasts. They did not delay any longer, rose to a high air, and flew in a straight line in the direction of Shennong Valley.

From the edge of the Great Array to Shennong Valley, the straight-line distance is about 800 kilometers. In order to recover his tired mental strength, Tian Xu took a medium-speed flight, which was about 150 kilometers per hour, and seven or eight hours later, it was midnight, and they arrived outside the mountain pass where Shennong Valley was located.
