In the past few days, there have been many thunderstorms in the river valley, which are unpredictable, and sometimes there will be several heavy rains in a day, which is very uncomfortable.

Wren: They're getting used to it.

Every time a rainstorm rains, Wren finds that the density of the elements in the valley changes dramatically, especially the lightning and water elements, and the values keep rising.

This time it was particularly violent, tripling in just two or three minutes.

The rain poured down so frantically that it obscured the view, and the river swelled, and the whole forest seemed to be soaked in water.

Wren's gaze pierced through the rain curtain and barely saw what was going on the cliff.

Flocks of thunderbirds flew up and met the lightning that fell from the sky, and the furious lightning struck them, not only did not cause harm, but instead seemed to recharge them, they screamed happily. The blue feathers shine, and lightning passes from thousands of thunderbirds to the top of the cliff to the clouds, as if they are holding a grand event to dance with thunder and lightning.

This scene is spectacular, but it also makes Wren very jealous.

He could see that the Thunderbird was increasing its own strength by absorbing lightning, which was also a way for many thunder-based creatures to enhance their strength.

Due to the geographical environment of the Ismu River Valley, the thunder and lightning elements are much higher than the average value, which causes abnormal weather.

This cliff is located in the center of the river valley, and it is the highest point within a radius of dozens of miles, like a lightning tower, so it is occupied by the Thunderbirds and becomes their territory.

The rain was still falling.

Wren looked at the murky river and said, "I'll go over and investigate now, you guys hide and wait for me here." ”

"Probing for what?" Bremet didn't understand.

Isn't it more dangerous to get close to a group of ptarmigans at this time?

Without much explanation, Wren took out a bottle of "underwater breathing" potion from the ring, drank it, and jumped into the rushing river, so that the dwarves had no time to stop it.

Poof.

Because of the body of steel, Wren actually weighed much more than he looked, already more than five hundred pounds, like a piece of iron sinking directly to the bottom of the river.

The river is so fast and deep that it is difficult to see even with the eyes of a soul a few meters away.

But this is a better way to disguise the breath.

Wren followed the current, and spent about five minutes half-swimming and half-running to the bottom of the cliff, inserting his palms into the riverbed, and then slowly floating upwards.

A pair of eyes opened a few centimeters below the surface of the river.

Wren's gaze pierced through the river and the rain curtain to look at the Thunderbird in the sky.

The big blue birds were carnivaling in the lightning and the torrential rain, and they flew so much that they didn't even notice that they were being observed.

In the eyes of the souls, their souls and elements are revealed.

Several thousand souls flew around in the sky, fast and fast, and always densely packed together, making their souls overlap and dazzle Wren.

He froze, his eyes fixed on the nearest Thunderbird to observe.

This is a mid-level Thunderbird with only three elements:

Lightning bolts, lightning sparks, swiftness.

It took less than half a second for Wren to make the identification, as did the other one. I watched hundreds of thunderbirds in a row, most of them were mid-level, and their elements were all three or four, and occasionally there were more prominent ones, with five elements.

Each Thunderbird has "Swiftness", and the rest are basically low-ring thunder spells.

Wren was an eye-opener.

The teacher's "Codex of a Thousand Laws" recorded a large number of spells, no matter what kind of elemental type, or arcane and shadow, the low-ring spells were the most, followed by the middle-ring spells, and the high-ring spells were drastically reduced, reduced to only a handful.

The same is true for thunder-based spells, with low-ring spells from one to three levels accounting for more than seventy percent.

Some of these spells are rare and hard to find.

However, in the souls of this group of thunderbirds, Wren could find the low-ring thunder spells on almost every "Thousand Spells Codex".

There were not even two or three spells that he had never heard of, nor were they included in the teacher's codex.

This is simply a paradise for the Thunder Elemental of the Fayin School!

However, there is no thunder and lightning affinity.

"What the hell......"

Wren in the potential water was depressed and could only continue to observe patiently.

The Soul Eye can see far ahead, but the range of distinguishing elements is still relatively limited, and only when the Thunderbird flies within a hundred meters above the surface of the river, Wren can seize the opportunity to identify it.

And there are often ptarmigans that repeat their flights, which have been observed several times.

However, those high-level thunderbirds that are most likely to have thunder and lightning affinity fly at the height closest to the clouds, and they rarely descend, and even the middle-level thunderbirds fly very high, he only identified a dozen, and the result is still nothing.

"It's not the way to go. ”

Wren's mind moved, and he looked at the cliff, most of the nests were empty, and the Thunderbird was flying in the sky, so he shouldn't notice anyone approaching the nest.

"It's worth the risk. ”

He didn't hesitate too much and inspired the Invisibility Ring.

A few seconds later, an invisible humanoid silhouette climbed up to the river, taking advantage of the heavy rain, and stuck to the bottom of the cliff.

Stealth, Wren lay on the ground to avoid being washed away by the rain and revealing his whereabouts.

He carefully chooses the landing point and casts a flash.

After each flash, it stops for a few seconds to make sure it doesn't alarm the Thunderbird, and then flashes to the next location again.

After a few spells, Wren silently landed on the top of the cliff.

He hid on the edge of a field where the ptarmigans had left, crouched in the grass, and looked up at the sky. At this altitude, at least one-third of the Thunderbirds will fly into the Soul Eye's identification range, and some Thunderbirds will fly over their heads for more than ten meters.

Wren held his breath and took the time to observe.

In less than five minutes, he had identified more than six hundred times, including dozens of mid-level thunderbirds.

It stands to reason that the probability of a mid-level bird having a thunder and lightning affinity is not low, and the Swift Shadow Thunder Blade Leopard that was fused at the beginning was a mid-level demonic beast.

But he hadn't discovered the thunder and lightning affinity yet, and he didn't know if it was bad luck or something else.

The rain gradually became lighter, and the lightning in the clouds weakened.

Wren secretly said that the rainstorm in the valley came and went quickly, and rarely lasted more than twenty minutes.

As the lightning event drew to a close, groups of ptarmigans descended and returned to their nests.

Wren wanted to leave immediately, but he was a little unwilling.

He noticed that the high-level ptarmigan was also flying low and seemed to be returning to its nest, so he decided to fight it and squatted on the top of the cliff without moving.

More and more Thunderbirds are falling, and the nearest one is just a few steps away from Wren.

Wren was like an invisible statue, not even moving his neck, maintaining a posture of looking up at the sky, not making any movement, and the blood-colored cloak concealed his breath, not leaking a single bit.

Finally, a high-level ptarmigan came into the observation range.

Wren rolled his eyes and made the identification as fast as he could, and saw five elements.

"Nope. ”

At the same time, more than a dozen mid-level thunderbirds were observed, and no thunder and lightning affinity was found.

The second high-level Thunderbird is here.

Its appearance was not much different from the high-level Thunderbird in front, its size was larger than that of the middle-rank, and its wingspan was close to eight meters, and Wren subconsciously glanced at it.

Six elements unfold before your eyes.

"Thunder and lightning affinity!"

Wren's eyes froze, and he almost couldn't keep his movements with joy, and even his heartbeat was half a beat faster, but fortunately, he reacted in time and suppressed his emotions, so that he was not exposed.

He locked onto the high-level Thunderbird and observed it carefully.

It has six elements, the most of any ptarmigan seen so far. In addition to the long-awaited Thunder and Lightning Affinity, there are also three arcane elements of "Electric Claw Technique", "Thundercloud Technique", and "Wind and Thunder Wings", as well as two physical elements of "Strength" and "Swiftness".

The strength is level three, which is not outstanding for the size of a high-level Thunderbird.

But its speed is actually five levels!

It's also an element of speed, and it has a very different effect on birds and land monsters.

The Thunderbird is already able to fly, extremely fast, and the fifth-level agility can make its speed skyrocket, and the role of the element is more reflected in the flexibility of flying, which is far from being comparable only to running on the ground.

Its body is as light as the wind, and at the same time as lightning.

Swooping down from the clouds, just a blink of an eye to the top of the cliff, about to hit the lair, the broad wings quickly flapped out an afterimage, buffering the force of the downward rush, the slender body like a feather fluttering into the lair, let Wren breathe.

"That's it. ”

Before Wren could figure out how to get out or kill the high-level thunderbird directly, suddenly, several thunderbirds in the sky who were returning to their nests let out a sharp cry.

This call immediately caused the birds to be agitated.

The clouds had cleared, the rain had gradually stopped, and five huge fiery dragons could be seen flying above the forest in the distance.

"Oops......"

Wren secretly screamed that it was not good, this was Cronouan who had come to him with the fire dragon.

He had Cronouan and the Fire Dragon following behind him for the past few days, catching up with them once every half an hour, but he didn't have time to inform them to avoid them, only to be discovered by the Thunderbird.

Sure enough, the freshly dropped Thunderbird immediately took off.

They gathered in the sky, like a large black cloud flying towards the fire dragon, covering the sky and the sun, and the cry was like a tide.

The strength of a single high-level thunderbird is far inferior to that of the Fire Dragon, but there are too many of them, and the wings of each Thunderbird are lit up with electric light, and the speed is extremely fast, and it flies half the distance in a few breaths, and then countless bolts of lightning erupt in the sky.

lightning arrows, lightning strikes, chain lightning;

Thunderclouds, Electric Sparks, Lightning Arcs, Electric Explosion Orbs, Electric Shock Beads;

The thunder and lightning elements within a radius of several miles were boiling, and hundreds of different thunder and lightning spells were crowded together, forming a chain reaction, like the "thundercloud storm" of the seven rings descending, carrying out a large-scale indiscriminate attack.

Even the dragon could not withstand such a huge momentum, so he could only flee in the wilderness.

However, the Thunderbirds are faster than the Fire Dragon, and they cannot escape.

Cronouan and the other Ultramarine, who were on the back of the Wyvern, were a little panicked, and before they could figure out what was going on, the Fire Dragon plunged into the forest uncontrollably and landed in the hiding place of Bremet and the two Ultramarines.

"Where's the boss?" Cronouan asked anxiously, not seeing Wren.
