Tianxing Garden, in the falling star pool.

Wu Yan used the power of the primordial element to condense into a protective body light around his body, and at the same time stimulated the blood vein of the divine machine, and a layer of faint blood light appeared on the surface of his body.

He had heard the Master Venerable Heavenly Star Supreme mention that the bottom of the Star Pool would produce a material called "Heavenly Mud". This item is not produced in Tianxing Island, but comes from the Yuan Cave, and has incredible fusion ability, which is an excellent auxiliary material for refining Yuanweapon-level weapons.

Wu Yan now has eternal silk in his hands, and if he wants to use this silk to refine a banner weapon, he will definitely use fusion auxiliary materials, looking at the countless heavenly materials and earth treasures in the entire chaotic world, there is no one more suitable than this "Heavenly Mud".

What's more, the level of "Heavenly Mud" is also equivalent to that of Eternal Silk, which belongs to the Eternal level of materials.

It's just that the Falling Star Pool is ten thousand feet deep, and the cold power of the dark water, as well as its own gravity, are dozens of times stronger than the chaotic water.

In the depths of ten thousand zhang, it is extremely difficult for the peak powerhouse in the late stage of Yuanzun to reach.

If it weren't for the fact that Wu Yan had already refined the Nine Palaces Rubik's Cube, and he had a divine bloodline that could adapt to various environments, he would not dare to easily try to enter the bottom of the Falling Star Pool.

Of course, the bottom of the Falling Star Pond is not full of "Heavenly Mud", and he must rely on the powerful sensing ability of the Yuan Shi Spirit to conduct a large-scale search at the bottom of the entire pool.

As for the Chaos Insect Cloud and Vine Demon that were devouring and eating in the Heavenly Star Garden outside, Wu Yan was not worried at all.

Before he entered the Falling Star Pool, he had ordered them to devour and absorb the heavenly and earthly treasures here to their heart's content and improve themselves. If you find a treasure that you can't devour, collect it and turn it in to yourself.

The efficiency of their treasure hunting should be faster than that of the others, so Wu Yan is not worried that he will suffer in this regard.

On the contrary, this trip to Luoxingtan to find the "Heavenly Mud" and the trip to the Nine Star Tianhe Waterfall are imperative.

"Heavenly Mud" is related to his refining of the Yuanweapon-level battle weapon "Slashing God Banner", so naturally there can be no mistake in the slightest.

And going to the foot of the Nine Star Tianhe Waterfall is more related to his use of primordial true iron to refine the natal treasure "Zhuxian Sword", as well as to improve his own cultivation and Heavenly Dao perception, and there can be no mistakes.

Previously, when he communicated with the Master Venerable Heavenly Star Supreme at Jiugong Mountain and River Terrace, Wu Yan had the intention to ask him how to improve his strength in the shortest possible time and refine the most suitable natal treasure for himself.

The advice given to him by the Heavenly Star Supreme was to enter the Falling Star Pool to find the "Heavenly Mud", as well as enter the Nine Star Tianhe Waterfall, and temper himself with the terrifying pressure of the waterfall, as well as the original true iron.

A few quarters of an hour later, Wu Yan had sunk to a depth of more than 5,000 zhang.

The power of the cold here is even more terrifying, and the pressure has also reached the limit that Yuan Zun can withstand in the middle stage.

There were very few Aquarium Yuan Beasts nearby, and even if there were occasionally one or two Swimming Fish and Water Snakes at the peak level of the middle Yuan Zun passing by, most of them swam away in a hurry, and they didn't seem to be interested in paying attention to Wu Yan at all.

Of course, this was not because Wu Yan was not worthy of their attention, but because the unique Heavenly Star Array Dao aura exuded from Wu Yan's body made them regard him as their own.

Although this Falling Star Pool is formed by the convergence of the water of the Nine Star Heavenly River, the Aqua Yuan Beasts growing in it are all free-range by the Heavenly Star Supreme, so they are naturally familiar with the breath of the Heavenly Star Array.

"What Master said is really good, this place is really suitable for extreme cultivation!"

At a depth of nearly six thousand zhang, Wu Yan clearly felt that even with the Yuan Light protection formed by the Nine Palace Rubik's Cube and the Blood Light Protection Body formed by the Divine Machine Bloodline, he had reached the limit of what he could bear!

With the power of the cold and the super pressure here, it is very suitable for refining one's own physical strength and strength essence.

Wu Yan frantically operated the Immortal Yuan Talisman in the center of the Nine Palaces Rubik's Cube, making it constantly fight against the power of the surrounding Yin and Cold, and at the same time stimulating the power of the divine bloodline as much as possible, so that it could resist the terrifying super pressure around it.

In such a terrifying cultivation environment, Wu Yan could clearly sense that the various heaven and earth primordial elements scattered around the Falling Star Pool were being absorbed and fused by his Immortal Yuan Talisman, and the Immortal Yuan Talisman was constantly improving and growing.

Previously, before entering the Falling Star Pool, with the help of the Heavenly Star Supreme, Wu Yan's Immortal Yuan Fu had been promoted to the peak realm of the third order.

At this time, under the stimulation of this cold power, the Immortal Yuan Fu was stimulated to its maximum potential, frantically devouring and absorbing all kinds of primordial elements around it, and strengthening itself.

And the super pressure made Wu Yan's musculoskeletal body gurgle, and the blood of the divine machine appeared at a glance, and the blood veins were under this heavy pressure, constantly fusing the different heavenly ways of Wu Yan's own perception.

The benefits of the Divine Bloodline were also fully displayed at this time!

Wu Yan could clearly sense that every time his bloodline fused with a different Heavenly Dao, the power of the bloodline would activate a part and grow by one point.

Whether it was the nearly 10,000 different formations in the Nine Palaces Rubik's Cube that changed the Heavenly Dao, or the lineage Heavenly Dao in the chaotic world that was perceived on the Heavenly Dao Tree, they were all fused with his divine bloodline in an extremely special way.

In this process, there was no rejection.

With such a terrifying fusion ability, I have to say that this bloodline of the Divine Machine Clan is really the most weird and powerful bloodline in the chaotic world.

I don't know how long it took.

Wu Yan's Immortal Talisman suddenly stopped rotating, and the blood light around his body suddenly disappeared and returned to his body.

In an instant, he clearly realized that the Immortal Yuan Fu had broken through the limit of the third order and reached the fourth order realm. And the Divine Bloodline has also successfully fused thousands of formations and Heavenly Dao changes, and its strength has been raised to an extremely terrifying realm, and it can actually resist the super pressure here with its physical body alone.

The chaotic world is indeed a wonderful place, and the speed of cultivation and improvement cannot be measured by common sense.

As long as there is enough accumulation of heritage and the right opportunity, the realm of strength can advance by leaps and bounds in a short period of time, and it is entirely possible to achieve it.

Of course, such a situation can only appear under the Supreme, and once it reaches the late realm of the Yuan Zun, it is not so simple to break through.

Some people will even be stuck in this realm for countless years, and there may even be a possibility of regression.

Along the way, especially after arriving at the Tianxing River, I basically couldn't see the existence of Yuan Zun and Yuan Beast, which is enough to explain everything.

The more you reach the heart of the chaotic world, the faster your cultivation will improve.

This is naturally related to the fact that the primordial energy possessed by the central zone is infinitely more abundant than that of the other areas.

Wu Yan continued to dive down.

More than half an hour later, the Immortal Talisman was running wildly again, and the blood light of the divine machine also lit up.

At this time, Wu Yan had already reached the bottom of the Falling Star Pond, and he had already stepped on the hard and cold rock under his feet.

The various heaven and earth primordials around them became more and more dense and powerful, and the power of yin and cold had also reached its limit, which could cause damage even to the powerhouses in the late stage of Yuanzun.

And the same is true of the super pressure.

With his previous experience, Wu Yan did not panic in the slightest, allowing the Immortal Yuan Fu to run wildly, and also allowing the Divine Bloodline to continue to fuse the Heavenly Dao changes of the formation, constantly activating the power of the bloodline.

However, in order to prevent accidents, he still sacrificed the Nine Palaces Rubik's Cube and fixed it above his head for guard.

This time, with the help of the Falling Star Pool's extreme Yin Cold power, Wu Yan's Immortal Yuan Fu quickly absorbed enough Heaven and Earth Essence to reach the fourth-order limit.

It's a pity that the Heaven and Earth Origin here was originally enough for the late Yuanzun realm cultivators to improve the realm, but Wu Yan's Immortal Yuan Talisman was too special, absorbing the Chaos Heaven and Earth Essence that could only be absorbed by the powerhouses of the late Yuan Zun, and he could only improve the fourth-order essence for his Yuan Fu, and he couldn't even break through the fourth-order limit.

The fourth-order limit, for Wu Yan, is equivalent to the middle stage of Yuanzun just stabilizing and consolidating. If he wanted to raise his realm to the peak realm of the middle stage of the Yuan Venerable, he had to raise the Immortal Yuan Fu to the sixth-order limit.

It seemed that his cultivation realm was much more difficult to improve than other Chaos cultivators.

At least, at the bottom of this Falling Star Pool, he could no longer continue to improve his cultivation.

Fortunately, the speed of the Heavenly Dao change of the Divine Machine Bloodline Fusion Formation did not stop, and on the contrary, it was still accelerating.

A few quarters of an hour later, when the Divine Machine's bloodline fused with three thousand different Heavenly Dao changes, the fusion finally stopped, and Wu Yan's physical body was completely adapted to the extreme cold power and super heavy pressure at the bottom of the Falling Star Pool.

He can already move freely at the bottom of the pond with ease.

Next, the natural search is to look for the "Heavenly Mud".

This is not too difficult for Wu Yan. He took out the ancient box that contained the primordial true iron. This box is not simple, it can be used to hold the original true iron, and it has been burned countless ancient runes by the Celestial Star Supreme, and it has incredible abilities.

This kind of treasure belongs to the space treasure specially used to hold all kinds of top-level heaven and earth treasures, and its interior has its own Qiankun.

This box, which contains primordial real iron, is obviously more suitable for holding a variety of different metals, stones, mud and sand materials. The other box containing the Eternal Silk was naturally more suitable for the materials produced by various other Chaos Creatures.

Wu Yan immediately launched a search at the bottom of the Falling Star Pond with Yuan Shiling.

Despite the limitations of extreme cold power and super pressure, his Yuan Shi Ling could only probe within a radius of thousands of miles, but the scope of this exploration was actually far beyond that of ordinary Yuan Zun late-stage realm powerhouses, and its efficiency was naturally extremely great.

The area of Luoxingtan is huge, and it is roughly estimated that it is at least a million miles in circumference.

If you want to search the entire bottom of the Falling Star Pool, it is obviously impossible for Wu Yan.

The target route he chose was very clear, that is, to find an underwater undercurrent, and then follow this undercurrent in the direction of the fall of the Nine Star Tianhe Waterfall.

Since the "Heavenly Mud" falls from the Jiuxing Tianhe Waterfall and is scattered in the Falling Star Pool, its distribution at the bottom of the Falling Star Pool should also be regular.

This law must be related to this underwater undercurrent.

Of course, these small rules and methods are actually obtained from the Master Venerable Heavenly Star Supreme.

Wu Yan unfolded the Yuan Shi Ling, continued to explore the bottom of the pool, and after more than an hour, he successfully found an underwater undercurrent.

The surging power of this undercurrent is extremely terrifying, and the cold power contained in it not only exceeds the limit of the cold power at the bottom of the pool, but also exceeds the limit of heavy pressure.

As soon as Fang entered the undercurrent, Wu Yan could clearly feel that his Immortal Talisman was running wildly again, and he was constantly absorbing a Chaotic Heaven and Earth Essence from the undercurrent that was different from all the previous ones.

This kind of essence does not seem to be all in the chaotic world, and it is likely to be the eternal essence in the Yuan Cave world mentioned by the master. Sensing this, Wu Yan was naturally overjoyed.

However, he also found that if he wanted to move towards the direction of the Nine Star Tianhe Waterfall with his potential, it was simply too difficult for him now.

The pressure brought by this undercurrent is far more than ten times greater than the previous extreme cold power and super heavy pressure!

Wu Yan was not surprised, and immediately sat down cross-legged on the spot, cultivating without distraction.

Soon, after absorbing a part of the Eternal Essence, the Immortal Talisman broke through the limit and reached the fifth-order realm.

It's a pity that there are not many eternal primordials in the undercurrent, and the distribution is extremely scattered, and it is very difficult to absorb them. A few hours had passed, and he had only absorbed a tiny fraction of it.

After reaching the fifth order, if you want to improve, it seems that the only way to improve is to absorb this eternal element.

Fortunately, the pressure in the undercurrent was more than ten times that of the rest of the pond bottom, and the number and speed of the Heavenly Dao changes in the Divine Machine Blood Fusion Formation were also more than ten times that of before.

After a few hours had passed, his Divine Machine Clan's bloodline had successfully fused all the Heavenly Dao changes that the Heavenly Star Array Dao belonged to, and the power of his bloodline had reached an unprecedented level.

It is no exaggeration to say that Wu Yan's current body bloodline is almost the same as the Nine Palace Rubik's Cube formed by Yuan Shi Mountain, and he has nearly 10,000 kinds of Heavenly Star Array Dao change abilities.

Don't say that resisting the pressure of this undercurrent, I'm afraid that even if you fight against the Nine Star Tianhe Waterfall, there shouldn't be much of a problem.

After all, the Nine Palaces Rubik's Cube is already a treasure. In other words, the strength of Wu Yan's current physical body is actually equivalent to a low-level elemental weapon.

No wonder the Heavenly Star Supreme said before that if Wu Yan wanted to improve his realm and refine his natal treasure, the best place was the Nine Star Tianhe Waterfall.

The two treasures that Wu Yan wants to refine, the Slashing God Banner belongs to the natal treasure of the Killing Primordial Spirit category, and the Zhuxian Sword belongs to the Killing Force category.

Before collecting the "Heavenly Mud", entering the Divine Machine Cave, and seeing Mo Tianyuan Yuanzun, the Divine Banner naturally could not be refined. However, this "Zhuxian Sword" can be tempered in this nine-star Tianhe Waterfall.

Whether it is the Force generated by the Eternal Element Talisman or the power of the bloodline generated by the Divine Bloodline, they all belong to power, but they are just different genres. With the help of the powerful pressure of the Nine Star Tianhe Waterfall, the primordial true iron was first forged into the shape of a sword weapon, and then the essence of the immortal element and the power element of the divine bloodline were all integrated into this sword.

As for the strength of its power, it is directly related to the strength of Wu Yan's own strength.

After the body adapted to the power of the undercurrent, Wu Yan immediately got up and walked along the direction of the undercurrent towards the Jiuxing Tianhe Waterfall.

After advancing for more than half an hour, Wu Yan suddenly sensed that just a thousand zhang ahead, under a black rock, there was a small ball of mud the size of a fist.
