The sky was just slightly bright, and the extinguished firewood was still emitting wisps of green smoke. A large red bird flashed through the branches, and there were several random sounds of 'plop, plop, ......plop, 'heavy objects slamming on the ground'.

"Who?!" Yun Tian, who was still asleep on the side, was awakened by this sudden strange sound, and stood up instantly. Yun Tian didn't seem to have come to his senses, blinking his eyes quickly, his gaze quickly sweeping around, but there was nothing out of the ordinary. Just when Yun Tian relaxed his vigilance slightly, he inadvertently looked down, instantly gasped, and subconsciously took a step back. I saw on the ground not far away, a beast that looked like it had died, lying motionless by the fire, with many deep scratches on its body, and blood was still oozing out.

Yun Tian picked up a wooden stick casually, walked forward tentatively, stabbed it a few times, and found that this thing was indeed dead, Yun Tian gradually relaxed his vigilance, and was completely awake at this time. Carefully observing the extremely miserable death in front of him, and from time to time he looked up vigilantly and looked around, countless thoughts flashed in his mind, this was a beast the size of an adult tiger, but the strange thing was that this beast had no fangs, and the elder on its head had a sharp horn the size of an arm, and it was covered in iron and hairless, and the stick was struck as if it was on a stone, making a 'bell-......' sound. Yun Tian couldn't help but be afraid for a while, such a hard body could leave such a deep wound, how terrifying the 'thing' that hurt it, thinking of this Yun Tian couldn't help but get nervous......

"Master, I'm back......" Just when Yuntian was puzzled, Xiao Kui Ling came out of the bushes not far away, holding a pile of various fruits in his hand.

"Little Kuiling, you can count it back, this is...... You've got it," Yuntian said, pointing to the dead beast on the ground.

"Huh?!Isn't this the Iron Stone Beast??, how did it die here?" could be heard from Xiao Kuiling's words, this masterpiece should not be what it did. Just when Yuntian was puzzled, a big red bird flew over from a tree not far away and landed on the beast on the ground. The remaining blood stains from the big bird's grasp, everyone suddenly realized.

"I understand, this must be made by Xiaohong, I guess I saw the master eating steamed buns yesterday, so I went to prepare a hearty breakfast for the master...... Hee-hee," Xiao Kuiling replied with a grin. At this time, I looked at the big bird, which was walking around the beast with a proud face, as if to show off.

"Breakfast?!Just eat it......" Yun Tian said with a little regurgitation as he looked at the bloody beast on the ground.

"That's right, although this ironstone beast is not a high-level spirit beast, but its meat can still be eaten, and the flesh of these strange beasts is not comparable to ordinary mountain beasts, eating its meat can not only be full, but also enhance the strength and strength of the master's body, this is an ability that ordinary beasts do not have......"

"Xiao Hong's thoughts, don't waste it......" Xiao Kui Ling had already started to light a fire and prepare to roast as he spoke. Yun Tian didn't say anything after hearing this, after all, it was good to have something to eat in this deep mountain and old forest, not to mention that it also had a certain effect.

"Xiaohong, such a big beast, you caught it...... I said, why was it so noisy last night" Yun Tian looked at the beast next to him, which was several times bigger than Xiaohong, and said with an expression of disbelief. On the other hand, Xiaohong kept nodding, Yun Tianzui was happy, she really picked up a big baby. After a while, the smell of the beast's flesh had spread, and Yun Tian, who had no appetite, instantly felt extremely hungry, and he hadn't eaten anything after a day's journey yesterday, plus he didn't sleep well at night, and his body was already close to collapse. Yuntian is no longer polite, and he tears off a large piece of meat when he goes up, and the aroma is even stronger at this time, coupled with its oily appearance, it is even more irresistible. Yun Tian devoured it, Xiao Kui Ling and Xiao Hong also took a big gulp, and after a while, half of the beast was only white bones.

Yun Tian sat on the ground to rest contentedly, feeling that the fatigue of a few days had been swept away, and his body was full of strength at this time. After she was full, Xiaohong flew away, only to disappear into the sky in an instant. At this time, there was already a lot of light, and after Yuntian cleaned up, he continued to walk towards the deep mountains......

At the beginning, there was still a way to go, which should have been left by the nearby villagers when they went into the mountains to hunt, but the more you walked in, the narrower the road, and the denser the forest, after walking for about half a day, there was basically no road, Yuntian followed Xiao Kuiling's instructions, and then walked forward, and the roar of wild beasts was heard from time to time along the way.

"By the way, Xiao Kuiling, is it to unseal tonight?"

"Yes, master, in tonight's unitary time, when the sun and moon alternate between yin and yang, when yin and yang are the weakest, it is the best time to carry out the yin and yang tribulation......"

"Okay...... Success or failure is here," Yun Tian whispered as if talking to himself.

"Are there any strange beasts around here, they won't rush out suddenly......" Yun Tian looked around as if remembering something.

"This place shouldn't be, besides, master, you haven't opened the soul cave now, and you don't have spiritual power, ordinary beasts won't attack your master, besides, don't we still have Xiaohong?" "Yun Tian walked forward for about an hour, and found a cave in a place full ......of trees and vines, the cave is about one person high, and the more you go inside, the more space there is, and you will reach the end of it by walking about ten zhang away. The cave was littered with fallen leaves and weeds, and some unknown beasts were scattered aside.

"This should be some kind of spirit beast's cave, it looks like it has been abandoned for a while......" Yun Tian said as he looked around in a panic.

"It should be, it's not surprising, in this kind of creatures in the deep mountains and old forests, they are all the weak and the strong, maybe when it will become someone else's meal......" Xiao Kui Ling said lightly.

"I think this place is good, let's be here tonight, I shouldn't be disturbed, master, you rest here for a while, I'll go out and prepare something, and I'll be back soon" Xiao Kuiling turned around and left after speaking. Yuntian lit a fire in the cave, during which Xiaohong flew in a few times, each time dropping a dying beast and hurriing away. Yun Tian smiled helplessly and shook his head on the side, this time he really didn't have to worry about eating.

At this time, the sun had set, and it was pitch black all around, and the fire flashing in the entrance of the cave was particularly dazzling in this dark night. A large red bird stood motionless on a branch near the entrance of the cave, as if protecting the cave. The eyes scanned the grass and trees around vigilantly, the slightest wind and grass could not escape its eyes, and the sharp gaze revealed an aggressive chill.

"I'm back," a hurried voice came from the entrance to the cave. Then a short 'little monster' ran in out of breath, holding in both hands a pile of colorful wild fruits that could not be named.

"You are in a hurry, what are you doing, what are these things" Yun Tian looked at Xiao Kui Ling, who was sitting on the ground on the side, engrossed in fiddling with the fruit.

"These are the things that will be used for a while...... Xiao Kui Ling replied without raising his head, his hands were still fiddling with the pile of fruits, as if he was classifying.

"What are these things? No...... It's all for me to eat, right?!" Yun Tian looked at the pile of fruits on the ground and said with a bitter face.

"Whew...... It's finally divided......"

"These are not for the master, but for me...... Hee-hee" Xiao Kui Ling stretched, sat on the ground, and picked up one from the far left of the pair of fruits as he spoke.

"It is extremely dangerous to carry out the Yin and Yang Tribulation, as you can see from the name, the slightest carelessness will divide the Yin and Yang......"

"Basically no one has used this technique for thousands of years, but it has been successful once in ancient times."

"Is it so dangerous" Yun Tian's brows tightened slightly, and he couldn't help but get nervous.

"Generally, there are strict steps to follow to unlock the seal, but at present, we can't do it, so I have no choice but to use the Yin and Yang Tribulation to help the master forcibly break the seal."

"To put it simply, the Yin Yang Tribulation is to forcibly break the seal by a strange beast with strong spiritual power, but it can't hurt the soul cave and life, this balance is extremely difficult to grasp......

"If you are not careful, you will fall short and even hurt your life. The fruit I have been eating recently, one is to strengthen my spiritual power, and the other is to strengthen my soul perception ......" Xiao Kui Ling picked up the last fruit on the ground, took a deep breath, and took a big bite.

"I said, you've been eating some messy fruits all this time, it turns out that it's for this......" Yun Tian suddenly realized.

"It should be almost the hour, we can get ready to start, there is Xiaohong guarding outside the entrance of the cave, and I will arrange a soul enchantment inside the cave...... It should be about the same."

"That'...... What do you need me to do?" Yun Tian looked at Xiao Hong and Xiao Kui Ling had something to do, but he, a key person, had nothing to do.

"Master, you only need to do one thing, that is, you must not run out of the enchantment I made......"

"Why should I run...... Haha" Yun Tian laughed a little puzzled, but after seeing Xiao Kuiling's expression, the smile on his cheeks slowly froze. A thought came to my mind, and only when it was extremely painful and unbearable would I be unable to help myself......

In the middle of the month, Xiao Kui Ling was in the cave, implementing the enchantment, and Yun Tian was on the side according to Xiao Kui Ling's instructions, cross-legged, adjusting his breathing, and feeling his soul cave.

"The time has come, the master must hold on......" Yun Tian closed his eyes tightly and nodded. Xiao Kuiling's hands were sealed, and a purple halo appeared around his palm. The spiritual power around Xiao Kui Ling's body visibly converged on his hands.

Immediately, Xiao Kui Ling was suspended in the air, and his finger lightly touched the center of Yun Tian's eyebrows, and at the moment of contact, the center of Yun Tian's eyebrows echoed like several lightning bolts, and a purple halo entered the center of the eyebrows.

Yun Tian's brows were furrowed, his breathing began to become uneven, and he couldn't see that there was too much abnormality from his appearance, I am afraid that only Yun Tian knew the pain at this time.

"Master, you must hold on, I'm going to break the seal with all my might......" Xiao Kui Ling was talking to Yun Tian with his divine sense. As soon as the words fell, I saw that Xiao Kuiling used all his strength, and the purple halo just now was instantly much stronger at this time.

Yun Tian grabbed his clothes tightly with both hands, as if he was about to scratch them, beads of sweat began to appear on his forehead, the corners of Yun Tian's mouth trembled slightly, and he let out a muffled snort from time to time.

Although Xiao Kui Ling closed his eyes tightly, he could clearly see every soul cave in Yuntian, whenever Xiao Kui Ling's spiritual power was about to enter the Yuntian Soul Cave, a powerful mark would appear at the mouth of the soul cave to prevent it from entering, and finally Xiao Kui Ling chose the previous crack seal and broke it with all his might.

At this time, the seal crack of that soul cave was constantly widening and deepening, and it seemed that it could be broken at any time.

Xiao Kui Ling carefully observed, the subtle changes in the soul cave seal, after the seal was broken, the spiritual power must be withdrawn in time so as not to hurt the owner's life. The crack has been formed from a small crack at the beginning, and now it has been completely sealed like a spider's web, which is a good sign, and the real danger is coming......

Xiao Kui Ling saw the opportunity and struck with all his strength, and the seal was broken, and at the same time, there seemed to be a strong hurricane blowing in the soul cave, and finally rushed out of Yuntian's body.

Yun Tian roared, his eyes flared, and the white lightning in his eyes flashed away...... Xiao Kuiling also fainted weakly and unconscious.
