Elder Solim was a little surprised to hear Wren's request.

"Don't you want to exchange weapons and equipment?" he asked, raising his hand and releasing a ray of light that appeared into a bundle of long crystal-shaped strange staffs, and said, "This 'Infinite Storm Staff' only costs fifteen thousand pounds of Source Crystal, it is one of the most powerful legendary staff in the world, and it is very suitable for you as many spellcasters want." ”

Wren had heard of the staff.

With the word "Storm" in its name, it does not refer to the caster of the exclusive wind elemental, but is capable of casting spells at an extreme acceleration, making spells pour out like a raging storm as if endlessly. In addition, there are multiple spells and support effects that can increase the caster's strength several times!

This staff has a long history, and its fame and power are no less than the "Akkas Scepter" in the teacher's hand.

Wren is very interested in it, not to use it himself, but to give it to Reslin, who can perfectly play Reslin's casting talent.

However, he shook his head firmly: "Your Excellency, I insist on my choice. ”

Back when he got the list last year, Wren studied it.

There are many items on the exchange list given by Elder Solim, and any one of them can be sold for a very high value when taken outside.

Those few pieces of legendary equipment are even more valuable.

But in Wren's eyes, the most valuable thing is not those physical objects, but the rune knowledge unique to the Titans. Based on his initial observation of Titan technology, this runic knowledge contains a complete energy system, which is somewhat similar to the electricity in the previous life, and in some ways more unique.

If he can master the Titan rune technology and understand it thoroughly, he may be able to study something incredible based on the experience of his previous life.

In contrast, just one or two pieces of Legendary gear are less important.

The most powerful hammer of Thor is already in your hands, and it is the most suitable for your own use, so there is no need to pursue other weapons for the time being.

Elder Solim saw Wren's firmness, and he was immediately a little reluctant.

The Storm Sanctuary has a total of twelve Thundercast Colosses, all of which he has personally created, and each one is equivalent to the legendary pinnacle of Titan Titan Titan in terms of combat power. At the beginning, it took a lot of materials and a lot of effort to rely on these colossi to support the defense system of the Storm Temple, although the impact of missing one statue was not so serious, but I always felt that I was at a loss.

When Wren asked if he could exchange the Thunder Cast Colossus last year, he saw that Wren was so knowledgeable, so he added it to the list proudly, never thinking that Wren could really take out 10,000 pounds of Source Crystal.

Unexpectedly, Wren not only took it out, but also really wanted to exchange it for the Colossus!

Those armor weapons, aren't they attractive?

None of the other traders were about to exchange for epic weapons and equipment, as well as all kinds of precious materials and gems, and all eyes were fixed on those few legendary items, which were listed as just a gimmick for traders to desperately collect source crystals.

Now there are really people who can redeem them, but they can't look at them.

This caught Elder Solim off guard, and he couldn't help but glance at Ren Gao a few times, only then did he realize that in just one year, Wren's strength had improved too much.

Even if measured by the eyes of a demigod, Wren's progress has been great!

"I have never met a young man as unique as you. Elder Solim was amazed, his expression straightened, and he nodded, "Since you are so persistent, then it will be as you wish." ”

Wren was overjoyed, "Thank you, Elder." ”

Solim rubbed helplessly, he waved his hand, and a door of light opened in the palace.

Bang!bang......

In the midst of the vibration, a ten-meter-tall thundercast colossus came out of it, its shape was born from the storm giant, and its limbs were thicker, like a giant wearing an extremely heavy set of blue armor, with many shiny runes painted on the surface, and the jewel-like eyes flashed with thunder and lightning, without the slightest emotional color.

When the Colossus walked, a sizzling electric current whistled from its body, and the thunder and lightning elements in the air were gathered to form an electrostatic reaction.

Wren felt the aura of danger in it.

With his current strength, he can make himself threatened, which shows how strong the Colossus's combat power is, at least it has legendary high-level attack power, and the defense is even more amazing, and the body made of Titan blue iron is definitely a real steel body.

Solim took out another huge ring, the pitch-black ring was cast from ordinary black iron, and the inner ring was inlaid with several silver points of light, like stars in the sky.

"This is the Nebula Ring. ”

Elder Titan handed the ring to Wren, and the ring as big as a bracelet automatically shrank to a size that adapted to humans, and he immediately put on this dimensional space ring worth 1,500 pounds of source crystals, and probed into the soul power, with an internal space of nearly one hundred cubic meters!

With such a large space capacity, there are so many things that can be put down.

Wren himself has dimensional space equipment, and the best is less than one-fiftieth of it.

The metallic touch sent back information that the main material of the Nebula Ring was not a dimensional stone, but a material that had never been seen before, and it was not a metal, it should be some kind of rare gemstone. It was inconspicuous to wear on the hand, like a black iron ring, and only a very close look would reveal a few subtle and complex runes on its outer ring.

Whether it's the understated shape or the practicality, Wren is very satisfied.

At this moment, Elder Solim appeared in his hand a thick tome, the pages of which were made of thin metal, but the contents were blank.

Elder Titan flipped the pages of the book in the air, and lightning bolts converged from all sides and slashed down on the book, forming lines of text content and rune images.

The lightning and thunder continued for several minutes.

When the last page was also filled with Giants and lightning runes, Solim closed the tome and the lightning subsided. But instead of handing the tome to Wren immediately, he gently rubbed the blue metal cover, his eyes were very complicated.

Wren didn't dare to urge.

"Alas......"

After a long time, Elder Solim let out a long sigh.

"Titan rune knowledge, this is the crystallization of the wisdom of our giant clan for tens of thousands of years, it has forged the glory of the giant empire, but the dependence on the source crystal has also indirectly caused the decline of the giant empire. Elder Solim's eyes were full of vicissitudes and feelings, "Now, I'm afraid I'm the last giant in the world to fully master the knowledge of the Titan rune. ”

"It's very different from the mainstream rune system of Erenus, more complex, and more difficult, and of course some of its knowledge is outdated and should have been eliminated a long time ago. ”

Solim looked at Athena and shook his head, "Most of the young people in the temple are unwilling to learn, and few of them are gifted. ”

Athena's face was slightly red.

She is too young, her main energy is focused on cultivation and fighting, and she has not yet begun to seriously study the knowledge of Titan Runes, and she is not confident that she can learn it well.

"In fact, before you, there were also traders who tried to master the knowledge of the Titan rune, although I only gave them a small part of the content, which is relatively shallow, but they are not willing to continue to go deeper, thinking that it is not worth investing too much energy, it is better to study the existing rune system, and it is not necessary to be limited by the source crystal. ”

"They can't be blamed for not getting a commensurate return for their huge efforts. ”

Elder Solim looked at Wren seriously, as if he was expecting some anticipation, and solemnly handed over the tome: "I hope you can surprise me again." ”

Wren picked up the heavy tome and nodded without making a promise.

He just tried, and there was no guarantee that he would definitely gain something, and even if he did research something, he probably wouldn't tell Elder Titan.

The exchange price for this knowledge of the Titan Runes is five thousand pounds of Source Crystal.

It is also expensive, because it is the crystallization of the wisdom of the Giant Empire, and knowledge is priceless, and it is definitely worth it to exchange it for only five thousand pounds of source crystals.

It is not expensive to say that it is expensive, because knowledge is reproducible, the cost of the book itself that carries it is negligible, and Elder Solim can sell it countless times, which can be described as a huge profit.

It can only be described as a win-win deal.

Wren put the rune tome into the Nebula Ring, and Elder Solim took fifteen blue metal ingots from his ring and stacked them on the ground.

These are the Titan Blue Iron, the unique skills of the Giant Clan.

"After deducting the previous three things, you still have five hundred pounds of source crystals left, one pound of source crystals for thirty pounds of blue iron, a total of fifteen thousand pounds here, you can count it yourself." The corners of Elder Solim's eyes jumped slightly, forging Titan Blue Iron was not easy, the process was tedious and boring, this was almost the only stock he had in his hand.

In the past, there were also traders who exchanged Titan Blue Iron, but it was rare to exchange so much like Wren.

After the deal is over, let the Titans in the temple work hard for a few months to replenish the inventory, or they will not have enough.

Wren casually picked up a piece of blue iron ingot, which weighed exactly a thousand pounds.

The metallic touch instantly revealed the composition structure of blue iron, which was smelted with as many as seven magical metals, of which the highest component was pure gold, accounting for more than half, supplemented by a small amount of Mithril and essentia black copper, etc., which were fused together according to unique proportions, and finally formed Titan Blue Iron.

The hardness, toughness, and magic conductivity of blue iron far exceed that of ordinary magic metals, and its applicability is extremely wide, but the biggest disadvantage is that it is heavy and expensive.

Its recipe and melting method are the top secret of the Titans.

Wren hadn't thought about the method of smelting to exchange for Titan Blue Iron, even if Elder Solim was willing to make a move, it would be sky-high, and the metal touch didn't know the process of smelting, but this didn't affect him to synthesize Titan Blue Iron.

Just know the proportional recipe and activate the metal to make any alloy you want!

"Thank you, Elder. ”

Wren kept his face silent and put fifteen thousand pounds of Titan Blue Iron into the Nebula Ring. This is the last time I will exchange blue iron, and in the future, I will collect magic metals and smelt them by myself, and the cost will be much lower than that of the source crystal exchange, maybe not even one-tenth.

He looked at the Thundercast Colossus, a little confused.

"Elder, how do I control it?"

"I'll teach you. Elder Solim put away the source crystal, was in a happy mood, and said, "You use your soul power to attract the thunder and lightning elements to form these runes......"

A series of intricate lightning-like runes emerged in front of him.

Wren hadn't learned the Titan runes yet, and he didn't know how they worked, but that didn't affect him from drawing a scoop from a gourd, which is the most basic quality of a wizard.

He watched it carefully a few times, and the soul power flowed, and the blessing of the thunder and lightning form attracted the elements.

Smack!

It only took one time for an identical string of Titan runes to form.

Elder Solim's eyes lit up, and Wren's hand showed his superb rune mastery skills, and he praised: "The students of the Holy Soul Wizard are really different, it seems that you usually put a lot of effort into this." As he spoke, he flashed to the chest of the Thundercast Colossus.

With a few clicks of mechanical transmission, the guards on the Colossus's chest opened to the sides, followed by three full layers of armor, blooming like petals, revealing the inner core.

Wren maintained the Titan Rune, staring intently at the core of the Colossus.

This is a miniature version of the Titan Furnace, but the volume is also equivalent to two or three large water tanks, the whole body is dark blue, the shell is made of Titan blue iron, carved with a dense rune array, when running, through a thick pipe to transmit energy outward, complex and extremely beautiful, reminded him of the engine in his previous life.

In fact, it is much more complex than an engine and more like a nuclear reactor.

And it's a miniaturized nuclear reactor!

This kind of technology would have been shocking in previous lives, even if its energy output was orders of magnitude lower than that of a real nuclear reactor, and it could only be seen in science fiction.

"That's what I want!"

Wren was extremely pleasantly surprised, the reason why he had to exchange for the Thunder Cast Colossus was to guess that there was a powerful power engine inside it.

Although it was much larger than expected and didn't seem to be suitable at the moment, he wasn't disappointed. Get it first and then study it slowly, even if you really can't use it, a thunder-cast colossus will not be a loss.

"This is the source of the Colossus's energy. Elder Solim explained, "It's a simplified result of the Titan Forge that consumes source crystals when activated, and you can control it this way. As he spoke, he reached out and pressed a crystal on the surface of the furnace.

A string of runes flashed across the surface of the crystal, which was quickly erased.

Elder Solim stepped away and motioned for Wren to come up.

Wren immediately understood what to do, and with a thought, the constant flight technique took effect and made him fly, enter the open chest of the Colossus, and inject the Titan rune in his hand into the control crystal.

With a buzz, the Colossus shuddered.

Suddenly, a strange feeling came to mind.

Wren felt a strong connection to the Thundercast Colossus, knowing its structure and state, seeing what it could see, and controlling all its actions with just his mind, as if he were an avatar outside of his body.

The Colossus also has an autonomous combat mode.

In this mode, you don't have to focus on control, the Colossus can patrol or stand guard according to the set route, and at the same time has the ability to identify friend and foe. This recognition is also determined by the owner, and various conditions can be set in advance to form different reactions, and if there is an error or a situation that it cannot handle, it will alert the owner to operate remotely.

The connection between the Thunder Cast Colossus and its owner cannot go more than a hundred miles at most.

There are also many features waiting to be explored, and these are the most obvious ways to operate them alone, and Wren is already amazed.

Even if he didn't be able to research anything in the future, the Colossus itself alone was worth 10,000 pounds of Source Crystal, no less than a piece of Legendary-level equipment!
