If you want to leave a Dao Thought, you must at least cultivate during the Tribulation Period, but Lin Feng is basically sure that this wisp of Dao Thoughts in his hand will definitely not only be the Tribulation Period, but ...... Immortals!!

The Tao of the Immortals!!

Just thinking about it, Lin Feng couldn't help but feel a burst of excitement in his heart, if this news spread, it was estimated that there would be a major earthquake in the entire cultivation realm.

Lin Feng is now extremely glad that he didn't choose to break through and escape before, otherwise he would have missed such a great opportunity, and now that he got this wisp of Dao thought, no matter how big the risk he took before, it was completely worth it.

After secretly being excited for a while, Lin Feng calmed down, looked at the Dao Nian light silk on his palm, looked up at the surroundings again, and muttered: "In this case, let's advance and refine the void here! But you need to finish it as quickly as possible, otherwise if you attract other monks, I am afraid that there will be more ......troubles."

Yes, he planned to refine this wisp of Dao Thought right here, and then take the opportunity to advance to refining the void, not that he was too anxious, but that he 'had to' do it, because...... Dao Nian cannot be taken away.

According to the memory of the Blood Demon Venerable, Dao Nian can only exist in the place where the monk fell, and if it is forcibly taken away, it will definitely dissipate, and Dao Nian itself is also very unstable, even if it is formed in the place, it may dissipate by itself at any time, so once Dao Nian is found, it is best to refine it immediately.

When he first saw this wisp of Dao Thought before, it seemed to almost disappear, and Lin Feng naturally didn't dare to delay, otherwise he would probably regret it if it really dissipated.

However, before refining this Dao Thought, the necessary preparations still have to be done, Lin Feng spent some time laying out a fifth-level defensive formation and a fifth-level phantom killing formation around him, so that in the process of refining his Dao Thought, before he starts to advance, even if an enemy appears, he can resist for a while, which is enough for him to react, as for after starting to advance, the Thunder Tribulation is the best protection, and no one will dare to come up.

As for the Spirit Gathering Array, it is naturally not needed, the Heaven and Earth Spiritual Qi here is already extremely rich, plus there are fragments of the Creation Realm Secret Treasure, which is more useful than any Spirit Gathering Array.

During this period of arrangement, Lin Feng had basically replenished the True Yuan he had consumed before by virtue of his super recovery speed, and then meditated and breathed for a while to adjust his state to the best.

"Whew...... So, let's get started!!"

Lin Feng sat cross-legged, holding the fragment of the boundary weapon in his left hand, and dragging the wisp of Dao Nian Light Silk in his right hand, taking a deep breath, he secretly gritted his teeth, and with a grip of his right hand, he grabbed the Nian Light Silk into the palm of his hand, and the moment his palm touched the light filament, the light filament seemed to be attracted, and in a slight flash, it drilled into his palm.

"Boom!!"

Just like the previous touch, Lin Feng had a roar in his mind, and countless information was surging, but it was countless times stronger than the previous one, and for a moment, he even felt that his head was about to be blown up, but fortunately, it was just an illusion, and except for the initial discomfort, there was no more pain.

This is the perfection of Dao Thought, unlike when Lin Feng received the memories of the Blood Demon Venerable before, he was almost mentally broken by a large amount of memory information, the information contained in this wisp of Dao Thought, it can even be said that it is not less than all the memories of the Blood Demon Venerable, but it does not have the slightest useless part, there is no 'life experience' that may affect the recipient's spirit, it is just a pure cultivation perception, which can make the recipient lightly 'digest' the perception.

From the moment the Dao Nian entered his body, Lin Feng entered an incomparably mysterious state, after a chill that was cold to the bones but not uncomfortable, he felt as if he was in an extremely cold world, and all the rest of the aura between the surrounding heaven and earth seemed to have disappeared, except for the ice attribute aura, which seemed to be materialized around him, and between the aura flows, it seemed to contain endless avenues, and it was incredible that he could understand a trace of the mystery!

I don't know when, countless ice crystals and snowflakes have appeared in the heaven and earth around Lin Feng, fluttering and sprinkling, and a layer of frost quickly accumulates on the ground, turning a radius of thousands of meters into an icy world in a moment.

A cold and majestic aura slowly emanated from Lin Feng's body, getting stronger and stronger, and as if under his influence, the ice crystals and snowflakes floating around him also began to stir, as if a blizzard was coming.

"Boom, boom......"

Time passed little by little, and suddenly, above the sky, the sound of thunder rolled in, and a black thundercloud quickly condensed, covering several miles in a moment, and directly below the center, it was where Lin Feng was.

Cloud Robbery!!

Obviously, after refining Dao Thoughts, Lin Feng had already found an opportunity to break through, so he triggered the Thunder Tribulation and prepared to attack the Refining Void!

"Crackle!!"

After a moment of brewing, the cloud whirlpool was finally 'accumulated', the thunder exploded, and the first thunder fell from the sky, and unlike the past, this time the thunder actually exuded an obvious cold atmosphere, as if it was integrated with the surrounding blizzard environment.

"Boom!!" In an instant, the first thunderbolt landed and hit the place where Lin Feng was, the ice and snow were raging, and the thunder was pervasive, completely covering his figure.

"Boom Boom Boom Boom ......"

One after another, the thunderbolts followed, and after nine paths, there was a slight pause, followed by the second group, and then the third group......

After the six nine fifty-four thunderstorms, the air and clouds changed, and the originally black clouds began to quickly diffuse colorful light, and in the center of the cloud whirlpool, the sky seemed to directly open a hole, as if connecting to another world, and seven stars of different colors faintly appeared.

"Boom!!"

In a burst of thunder that was louder than any before, the colorful tribulation thunder came as scheduled.

......

In this Burial Immortal Valley, in the desert area before this forest area where Lin Feng was located, it was when Lin Feng crossed the Void Thunder Tribulation, or rather, when the Colorful Tribulation Thunder came......

"Hum!!" The entire desert suddenly trembled violently, the wind was fierce, the yellow sand was flying, and countless demon beasts that lived deep underground drilled out of the ground and fled in all directions in panic, the scene was extremely chaotic.

A mysterious aura of vicissitudes emanated from the depths of the ground somewhere in the desert, as if some existent who had been sleeping for an unknown number of years had been awakened......

......

At the same time, in the Gangfeng region on the outskirts of the Burial Immortal Valley.

The four figures quickly rushed out, and after getting out of the danger area, the four of them breathed a sigh of relief at the same time, and each of them showed a look of happiness in their eyes, but also a trace of doubt.

These four people were naturally the three men and one woman who Lin Feng had felt when he passed through the Gangfeng area before, and they had only finally walked through this Gangfeng area until now, but the speed seemed to be faster than expected.

After confirming that the surroundings were safe, the four of them each began to pranayama, and after a while, the old woman finished pranayama, she looked at the other three companions who had also finished pranayama, and said, "It's really strange...... Why did this wind suddenly weaken? But fortunately, otherwise we would have had to work hard to get out. ”

The purple-robed old man at the head also had a contemplative look on his face, he turned his head to look at the direction of the depths of the valley, and frowned slightly: "The aura of heaven and earth here seems to have changed a lot, and the wind has weakened, I feel as if the aura of heaven and earth has gathered in the depths of the Burial Immortal Valley, and it is very likely that something abnormal has happened there......"

The old man in white on the left looked at the sky in the distance, suddenly raised his eyebrows, and said in surprise: "Look! There seems to be a vision over there!"

Everyone stared at the words when they heard this, and sure enough, they saw that there seemed to be a vague light flickering in the distant sky, and there seemed to be a faint sound, but there was a sound of the wind behind them, which was really unreal.

"That's like...... Is it thunder? Do you hear thunder?"

"Thunder, but I think it's colored?"

"It's like a colorful glow, is there really some treasure born?"

"Whatever it is, we'll see it when we go over! Without further ado, let's go! If it's a treasure, it's not in vain that we've taken the risk of coming here." ”

Everyone talked a few words, and finally the purple-robed old man made a decision, and as soon as he waved his hand, the four of them set off again and hurried towards the depths of the Burial Immortal Valley......
