Bang bang bang......

Wren controlled the Thundercast Colossus to move, the furnace in his body roared, the energy was transmitted, and the heavy metal soles stepped on the ground and made thunderous footsteps.

With such a huge body, the speed is not slow, much faster than ordinary people, probably equivalent to the second-level "swift", but it is not very flexible compared to high-level transcendentals, and it is a little clumsy.

In addition, he also found that the Colossus's reaction speed was not sensitive enough, and there was a slight delay in some movements, which should be the result of the Colossus's large body and weight, after all, it was only a mechanical creation, and its agility and reaction were not as good as that of a real giant.

But this does not affect the combat effectiveness of the Colossus.

It draws energy through the Titan Forge in its chest, activates the rune array engraved on its body, and unleashes a variety of lightning spells.

For each melee attack of the Thundercast Colossus, the fist and giant palm weighing up to 10,000 pounds can be attached to lightning, which are "Thunder Trampling" and "Thunder Punch", respectively, which are equivalent to the Six Rings spell and have no cooldown.

The terrifying power of its own weight combined with lightning damage made even the legendary high-level not dare to take a heavy punch from it.

The eyes of the Colossus can also shoot "electric rays" to cut enemies at high temperatures; guide the seven-ring spell "Lightning Storm" to bombard targets within the range; the waist has a constant "electrostatic field" to slow down approaching enemies; the left arm can activate a "blue crystal shield" to resist attacks from the front; the right palm condenses energy to form the "Sunshine Gun" as a melee weapon, which has physical damage; when necessary, it can also inject more energy into the "Sunshine Gun" and throw it into the "Lightning Javelin" of the eight rings, which is the Colossus's longest-range The most powerful attack.

These spells and abilities make up for the Thundercast Colossus's lack of agility and speed.

Even if the Colossus can't escape enemy attacks, its body forged from Titan Blue Iron has strong defenses and incredible magic resistance, making it almost impossible to destroy it by ordinary means.

Such a thunder-cast colossus is placed on the battlefield, which can be called a weapon of mass destruction.

"Wren, are you happy with it?"

Elder Solim asked with a smile, a smug look on his face.

"Thank you, Elder. Wren withdrew from manipulating the Colossus and boasted, "It is truly one of the greatest creations of the Giant Empire, I have never seen such a powerful mechanical Colossus!"

Solim nodded reservedly, with a little reluctance in his eyes.

Wren sensed his complicated mentality, and was afraid that the other party would regret it, so he quickly put the Thunder Cast Colossus into the Nebula Ring. Fortunately, I exchanged this huge ring, which is enough to put down three colossas, otherwise it would be a problem to take the colossus away.

After the transaction was completed, he was about to leave, bowed down and said, "Your Excellency Elder, please allow me to retire first. ”

"Don't you exchange anything else?" Solim raised an eyebrow, he guessed that Wren must still have the source crystal in his hand, and he didn't take it all out.

"Not for now. ”

Wren didn't hide it, he did have more than four hundred pounds of source crystals, but he had to keep them for his own research, and the Thunder Cast Colossus also needed source crystals as fuel.

There are also a few things on the redemption list that are extremely attractive.

For example, as long as 1,000 pounds of source crystals, you can exchange for a complete set of "Titan Power Armor", each part is epic equipment, with different enchantments, and a complete set can also increase the "power" by one level, which is very suitable for yourself, but the source crystal is not enough.

There is also the legendary staff "Immersturm", which is almost a tailor-made staff for Leslin, and must be exchanged in the future.

"Annum's Dragon Slaying Sword" requires 50,000 pounds of source crystals, and if you don't need it, you can take it to auction and make a lot of money.

The Mithril Mine near Dragonspine City can produce about 50,000 pounds of Source Crystal Ore every year, and can refine 2,000 pounds of Source Crystal. After upgrading the mechanical mining equipment, the output can be higher, and it is possible to double, in short, there will not be too much shortage of source crystals in the next few years.

As for the most expensive "Titan Furnace" on the list, it costs 500,000 pounds of Source Crystal, and it may not be so much to hollow out the entire Mithril mine.

Seeing that Elder Solim looked a little disappointed, Wren revealed slightly, "I will visit the temple often in the future, and I hope it will not disturb the elders." ”

"No, no, no. Solim laughed, "The Storm Sanctuary welcomes you at any time. ”

He looked at Athena, "You send one to Wren for me." ”

"Okay. ”

Wren saluted Solim and followed Athena out of the Crucible Sanctuary.

"How did you collect so many source crystals?The other traders can take out a thousand pounds of source crystals, which is very powerful, and the elders are all taken aback by you!" Athena's bright golden eyes were full of curiosity, she didn't have any scruples like the Titan elders, so she asked directly.

Wren naturally wouldn't tell her, and said with a smile: "It's a secret." ”

"Okay. Athena was not very interested in this, "Tell me about the empire, besides your teacher, what other holy soul wizards are there?The empire only has holy soul wizards, and there are no other saint-level transcendents above level 20?What is their strength?It is said that there is also a steam engine that does not rely on source crystals, and can carry hundreds of people to run on the railroad tracks......"

This series of questions was thrown, and Wren didn't know where to start.

Along the way, Athena listened carefully to Wren's words, and it seemed that everything could arouse her curiosity, and from time to time she interjected a few times and asked questions.

The Crucible Sanctuary wasn't that far from the teleportation platform, but this time, Wren walked for more than two hours to complete.

Seeing the legendary giant Lodal guarding the Legendary Array, Wren breathed a sigh of relief, finally arrived, stopped at the edge of the platform, and said, "Lady Athena, it's time for me to go back." ”

Lodal looked at him in surprise, wondering how Athena had come together with this human.

Athena asked nostalgically, "When will you come again?"

"That's not exactly. Wren smiled, "It should be within a year, depending on how many source crystals I collect." ”

Athena sighed softly, as if she felt that a year was too long.

Wren looked at the bright-eyed giantess, like a young girl who had not been deeply involved in the world, and reminded: "Lady Athena, the outside world is indeed very exciting, but it is also very dangerous, you must not only see its bright side, but also pay attention to its dark side. ”

"I understand. Athena retracted her smile and said, "The elder also said that many people in the main material realm have malicious intentions towards the Storm Giants, and they take our people as prey, and it is safest to stay in the temple, I just ...... Just ......"

She stopped talking, not knowing how to describe her thoughts.

"The world is so big, I want to see it?" Wren answered with a smile.

"Yes!"

Athena's eyes lit up, she nodded again and again, and said happily: "The world is so big, I want to go and see it." Rennes, what you said is very good! I think of the mountains of the world, see the snow on the world's highest peak, stand on the floating city and look down on the bustling city, admire the clouds in the sky, and the waves of the endless sea, and the cold winds of the northern part of the New World...... There are so many beautiful scenery waiting for me to enjoy!"

"Not only the main material realm, but also the many planes of Erenus, the celestial realm, the ether and the shadows, and even the abyss, I want to go in and see ......"

"Not to mention so many races and civilizations, it would be a shame to only stay in the Temple!"

Athena's eyes seemed to glow, and the infinite yearning was written on her beautiful face, and finally looked at Wren seriously, "Can you understand what I mean?"

"Of course. ”

Wren nodded, a look of deep approval.

But he was complaining in his heart, this giantess was similar to the girl who had been at home for a long time in her previous life, and she wanted to leave everything behind all day for a trip that she said would go. At least in her previous life, she still had the Internet, and she could "cloud travel" at home, and Athena could only listen to the outside world from books or other people's mouths, and she was really embarrassed for decades.

"I wish you the day when your wish will come true. ”

Wren's sincere blessing made a crooked idea in his heart, if he could fool Athena out, he would have another powerful thug.

"Thank you. Athena happily accepted the blessing.

Lodal, who was next to him, heard the conversation between the two and couldn't help but say loudly: "Athena, no one is allowed to leave the temple without the order of the elders. Human, you can leave. ”

Athena's eyes darkened.

Wren also stood on the teleportation array.

At this time, Solim's voice came from the air: "Athena, when you are promoted to the Legendary High Rank, if you can pass my test, I will allow you to leave the Temple." ”

"Elder, that's what you said!" Athena's eyebrows fluttered, and she almost jumped up with joy.

Elder Solim didn't respond, but the meaning was clear.

Wren's face was surprised, and he didn't understand what Elder Solim meant, but he still smiled, "Congratulations, ma'am, I'm going first." ”

After saying that, he nodded to Lodal, who was also in surprise, and triggered the teleportation.

Athena watched Wren's figure disappear, and after a few seconds of distraction, she suddenly said, "Uncle Lodar, next time Wren comes back, please notify me immediately." ”

Lodal was a little reluctant, but finally agreed, "Okay." ”

"Thank you, Uncle Lodal. Athena turned away, her steps brisk, now she just wanted to go home and meditate hard and hone her fighting skills.

Wren appeared in the ruins palace beneath the valley, the portal behind him closed, and the six massive stone pillars fell silent and regained their calm. With a casual move, Thor's hammer returned to his side, and then used the arcane torrent staff to directly open a portal that led to a hundred miles away, and stepped into it in one step.

Before dawn, Wren returned to the base of Fort Kong.

After two teleportations, he returned to the top of the tower in Wezeland, and released the Thundercast Colossus from the Nebula Ring, controlling it to open the three layers of protection on his chest, revealing the inner core.

This shrunken Titan Forge was only a dozen times the size of the one in the Temple, but it was still surprisingly large.

It is an ellipsoid, about two meters in length and diameter, and the shell made of Titan blue iron is extremely hard, engraved with dense rune arrays, which are always in motion, and each rune emits an electric blue light, which can faintly penetrate the structure inside the furnace.

Wren reached for his hand against the furnace, and the metallic touch began to take effect.

In just an instant, a large amount of information poured into his mind, and the entire structure of the furnace was reflected in his heart, but this was only a part of the whole, some of the structure of the furnace was not metallic, and the flow of runes and energy could not be sensed, which did not allow him to immediately grasp the principle of the furnace.

The compression and combustion of the source crystal, the energy conversion and output, and the functions of hundreds of rune arrays......

Wren saw the clouds.

He studied for a whole day to roughly figure out the performance of the furnace, which, as expected, released energy orders of magnitude lower than a nuclear reactor, but orders of magnitude higher than an internal combustion engine and an electric motor, somewhere in between.

Without instruments and measuring tools, Rennes could not produce accurate data.

He could only estimate that one pound of source crystals could make the Thundercast Colossus weighing 150,000 pounds run for half a month, and if the volume and weight of the Colossus were reduced, it could last even longer. Of course, when the Colossus is running at full strength, it will definitely speed up the consumption of Source Crystals.

The energy released by the furnace is a kind of electrical energy, but it is different from the electricity energy of the previous life, it is a kind of magical energy, but it follows some principles of electromagnetism.

This made Wren feel very tricky while being happy.

The Titan Furnace is obviously different from a nuclear reactor in that it can be built very large, such as the one in the Storm Sanctuary, which is tens of meters in diameter, or it can be built very small, and it can be used as the power source of the Colossus, which is hundreds of times different in size.

The energy it outputs depends on the volume of the furnace, which is proportional to the size of the furnace.

Wren has no idea about maximizing the Titan Forge for the time being, he wants a minimized Forge Furnace. It's best to shrink it down to a size that can be carried by a single person, so that the armor of the Ultramarines is no longer just an empty shell, but a real power armor!

This miniaturized furnace not only powers armor, but can also carry a range of electrical weapons.

Wren had a lot of ideas to experiment with.

However, after his exploration, he found that it was extremely difficult to shrink the Titan Forge Furnace.

The furnace of the Thunder Cast Colossus should be the limit of what the giant clan can do, and continue to shrink, one is the test of casting technology, and the other is that the control of energy must be more refined.

Neither of these problems is easy to solve.

At least Wren thinks that the giants have no solution, as can be seen from the Colossus's combat mode, and that delay and inflexibility are the result of too rough control of energy.

Wren has activated metal and is confident that he can solve the first problem.

But there is not much certainty about the second problem.

The giant clan has not been able to complete the research of the Titan Furnace for tens of thousands of years, even if he has the experience and ideas of electronic machinery in his previous life, he may not be able to apply it, and this kind of pearl in industrial manufacturing, behind it is the hard work and wisdom of countless people, and it is almost a dream to reproduce it alone.

Wren let out a long breath.

He sat in front of the window and looked at the floating city outside the tower, pondered for a long time, and finally decided that no matter how difficult it was, he could not give up.

After all, this is Ehrenus, not Earth, a world full of supernatural powers, with miracles everywhere that cannot be measured by the rules of a previous life.

What he couldn't do on his own in his previous life, it wasn't impossible with Ehrenus.

Even if it takes an indefinite number of years of hard work, five, ten or even a hundred years, as long as there is a glimmer of success, it is worth trying.

Once the research is successful, the gains will be immeasurable!

Wren got up and returned to the table, took out the thick Titan Rune Knowledge Classic, turned the first page, and began to study intently.
