Unbeknownst to Rocky what happened to Erin in sending Jasy away, he returned to the lab after the two left.

Although he did not lose hope in negotiations, Rocky knew that he could not just count on negotiations, he also needed a back-up plan, and this plan naturally relied on magical runes.

So after returning to the research room, he asked Lilia to bring his Sky Demon Armor over!

"Are you really going to do that? Isn't it too soon......"

After waiting in the research room for a while, Lilia took the Sky Demon Warframe, but she looked a little uneasy when she handed it over to Rocky.

Because Rocky had already told her what he was going to do, he was going to draw runes on the Sky Demon Warframe!

This decision surprised Lilia, after all, Rocky had just learned runes!

Although it is an inevitable trend to use runes on the Sky Demon Warframe, wouldn't it be too early for Rocky to do this now? You must know that he only has this set of Sky Demon Warframe, and if it is broken, there is no place to cry.

"I just want to test it, and even if the rune fails, there will be no side effects, at most it will consume some mana, and the Sky Demon Armor will definitely be fine. ”

That being said, Rocky didn't know what he was doing, but he had to.

How important the Sky Demon Battle Armor is to himself, Rocky knows better than anyone else, this thing has always been his treasure bump, how can he not cherish it? Unfortunately, due to the situation, he had to take the Air Demon Battle Armor to risk.

His only capital now is the magic rune, but with the current strength of Thunder Eagle City, he can't let outsiders know about the existence of the rune, so Rocky doesn't have many options, and even only one option is left, that is, to use the rune to enhance his strength.

Either use the runes on normal equipment to make normal equipment become rune equipment, or use runes on the Sky Demon Warframe to make the Sky Demon Warframe stronger.

And for Rocky, who already has the Air Demon Battle Armor, he naturally wants to use the runes on the Battle Armor, and he can't just put the more powerful Air Demon Battle Armor without it, but wear rune equipment, right?

So he had to take that risk.

But for Rocky's approach, Lilia not only felt very reckless, but also thought it was completely useless, in her opinion, even if Rocky's strength became stronger, what could she do?

It's just that she also saw that Rocky seemed to have his own plans, so she didn't stop him in the end, and she was afraid of disturbing him to draw runes before leaving.

After that, only Rocky, a pen, and a set of air demon armor were left in the research room.

Placing the breastplate of the Sky Demon Battle Armor on the research table, he did not immediately draw the runes on it, but carefully studied and pondered it inside and out.

The reason why the Sky Demon Warframe is called the strongest individual soldier equipment is not only because it is inlaid with magic stones, but also because a set of Sky Demon Warframe contains far more technology than imagined, so even if Rocky has mastered the first-level magic runes, he can't just apply the runes to the warframe.

Because if he wants to use runes to strengthen the Sky Demon Warframe, he must first figure out the magic energy drive system of the Warframe, and then connect this drive system to the runes, so that the Warframe can use the magic energy provided by the runes.

The technology and technology involved in this are so complex and high-end that no one can figure it out unless they are professionals who make battle armor, and Rocky is even more impossible.

But even with all the difficulty, he decided to give it a try.

It's not that he doesn't think about himself, it's because he thinks differently.

Rocky didn't want to drastically transform the Sky Demon Warframe, he knew very well that he didn't have this ability, let alone him, even the most senior Warframe Maker couldn't do it, after all, the Magic Rune is a new technology, and without research and experimentation, no one has the ability to directly replace the Philosopher's Stone on the Sky Demon Warframe with runes, which involves too much technology and is too complicated.

So his real idea was to treat the Sky Demon Warframe as ordinary equipment, and then make it into rune equipment!

To put it simply, it is to draw runes on the air demon armor, and under the condition of ensuring that the original combat power of the armor remains unchanged, it will increase the power of a layer of rune equipment, and use this method to strengthen the relative armor!

This is a new idea that only Rocky can think of, no, it should be said that only he can think of it!

Because before the appearance of the magic rune, both the empty magic armor and the magic equipment relied on the magic stone to provide magic energy, which made it impossible for a piece of equipment to be both an empty magic armor and a magic energy equipment, and the two could not coexist.

But now the magic rune has appeared, as a substitute for the Philosopher's Stone, the rune can not only replace the Philosopher's Stone, but also coexist with the Philosopher's Stone!

So Rocky thought of such a way to strengthen his Air Demon Warframe, he wanted to make his Sky Demon Warframe maintain its original power while being able to become a set of rune equipment!

This idea perfectly bypasses the high-end technology involved in the Sky Demon Warframe, and only needs to treat the Warframe as ordinary equipment, and then make it into rune equipment.

It's not easy to craft rune gear, but don't forget that Rocky still has a research notebook in his hand.

Wensel's original intention in developing the Magic Rune was to replace the Philosopher's Stone, and then make the Magic Equipment become Rune Equipment, which greatly increased its power, so he left a note detailing how to use Runes to craft equipment.

With this notebook, Rocky can make rune gear at all!

And if he can succeed, then the strengthened Sky Demon Battle Armor will definitely be upgraded to a higher level in terms of combat effectiveness!

"Let's get started......"

After carefully observing the cuirass in the Sky Demon Warframe suit for a long time, Rocky was ready to do it.

I saw him pick up the magic pen, and then drew a rune in the inner lining of the breastplate.

In order not to let people find the clues, he made full use of the convenience of the runes and drew them directly in the inner lining of the battle armor, so that it would not affect the effect of the runes, nor would people find out how different their battle armor was.

With his stroke, a rune was drawn and lit up with a faint light.

This shows that the rune has been successfully drawn, and the rune already contains magic energy, but this is not the end, the magic energy contained in the first-level rune is very, very small, and even the miniature magic stone is not as good, if you want to make it exert its real power, you must rely on the number to do it.

According to Rocky's estimates, he had to draw at least a hundred first-level runes on the cuirass in order to really increase the defensive power of the cuirass, which was a big project.

So after successfully drawing one rune, he followed up with a second rune, then a third......

Most of the day passed like this, until the evening when Lota left the research room, and by the time he left, his magic had been completely depleted.

Early the next morning, Jassy came to see Lodge, as if to finalize the deal as soon as possible.

This was a bit unexpected for him, he originally wanted to delay it, but he didn't expect Jassy to be so proactive, so he had to send someone to call Erin.

When Erin arrived at the City Lord's Hall, a new round of negotiations began.

A morning has passed in a blink of an eye, and as for the result of this negotiation, it is still the same as yesterday, almost no result has been reached, and Jassy is still not giving an inch, insisting that the price increase of 30% will not be relaxed at all.

On the contrary, Erin's performance today seems to be a little inaccurate, yesterday she was still able to have a relationship with Jassie, but today she is obviously a little absent-minded, which is also an important reason why the two sides have not negotiated anything.

In desperation, Rocky had to find another excuse to forcibly suspend the negotiations, intending to give Erin some more time to figure out a way, but Jasy did not give Rocky this chance.

"Lord of the Castle!"

"Yesterday, there was an urgent notice from the Chamber of Commerce, and the headquarters had something important to call me back, so I can only stay here for one day at most, and I hope that the city lord can give an accurate answer tomorrow and finalize this matter as soon as possible." ”

After saying this, Jassy turned to leave......

The meaning of his words is obvious, that is, he doesn't plan to delay it any longer, he is forcing Rocky to make a decision as soon as possible!

"My lord, I'll go first...... too"

When Jassy left, Rocky originally wanted to discuss with Erin what to do, after all, the people were already leaving, and they couldn't delay it any longer, but they didn't expect Erin to leave without saying anything.

"Rocky, Erin is a little strange today. ”

When Erin leaves, Lilia tells Rocky that even she can see that something is wrong with Erin today.

"Something is wrong...... Rocky was also puzzled, wondering what was wrong with Erin.

"I'll ask. ”

After saying this, Lilia didn't wait for Rocky to agree, and chased directly out of the city lord's hall.
