Chapter 430: Collar

Sean stayed in the underground metal city of Eska for half a year.

The main reason was that there were too many experiments, not only about the mermaid Eliza, the constructor Yuli, but also about Sean's own experimental arrangements, which were also a lot.

After half a year of experiments and improvements, Sean's values ​​in all aspects changed again.

Mental power: 1

Magic power: 3

Physical fitness: 4

The mental power value grew faster, which came from the fact that Sean had almost never stopped growing and improving his knowledge in the past six months.

The growth rate of magic power can only be said to be average.

What made Sean a little dissatisfied was that his physical growth had fallen into a bottleneck period in the past six months.

You know, in the past six months, Sean did not fall behind his Jade Fire Tempering Experiment.

The reason why the physical growth rate slowed down was not because its overall growth rate was slower, but it was slower than the growth rate six months ago.

As a first-level magician who also embarked on the path of jade fire tempering, Sean's growth rate definitely surpassed other first-level magicians of the jade burning fire sect.

But despite this, Sean was not satisfied.

"It was during the time when the tourmaline was here that my physical fitness grew faster."

"That special life magnetic field..."

"No, I must find a way to bring it to the Jade Origin Holy Tower to live permanently!"

In the laboratory, Sean walked down from the experimental table, holding the crystal ball in one hand, looking at the values ​​recorded in it, and couldn't help but sigh.

It has only been more than half a year since they parted, and Sean missed tourmaline a little.

Sean's own plan is to break 200 in both mental power and magic power before arriving at the Western Islands, and to increase physical fitness to more than 140 points.

This plan is still a bit too difficult for Sean to achieve with his own efforts.

To achieve it, he cannot do without the help of tourmaline.

After walking out of the body refining laboratory, Sean drank a nutrient potion to replenish his physical strength, and then entered the alchemy laboratory next door.

In the past six months, Sean has also gained new insights into the research of manned space equipment.

Not long ago, he just completed a new product and used it on Yuli as soon as possible. The metal hatch of the alchemy laboratory opened under Sean's magic mark.

As Sean walked to the center of the laboratory, a translucent cover opened from the middle, revealing a dark metal ring inside.

The functions of this metal ring are basically normal, and the only thing left is the testing phase.

Unlike the beautiful azure crystal necklace worn on the neck of the mermaid Eliza, Sean's black metal ring is much worse in terms of appearance.

There is no way, this is also Sean's first time making it.

Being able to make it successfully already indicates that Sean has great potential and foundation in the field of alchemy.

If you pursue external beauty, it will be a bit difficult.

At least Sean can't do it at this stage, and he needs to hone it for a while.

As Sean entered the alchemy laboratory, the constructor Yuli soon followed him in.

As time goes by, Yuli behaves more and more naturally in front of Sean.

This is mainly related to Sean's personality. He usually does not have any strict master-servant requirements for Yuli.

Because Yuli often helps Sean with some experiments, Sean also gives her great autonomy and access to the laboratory.

At this time, Yuli just came from the metal warehouse next door. She heard the movement of Sean finishing the body refining experiment, so she rushed over as soon as possible.

It may be the effect of Mirachi Soul Treasure Book, or it may be caused by Yuli's own thoughts. Sean's female slave is more attached to him.

During the period when Sean entered the alchemy laboratory, Yuli was tinkering with her constructed puppets in the metal warehouse next door.

Don't look at Yuli's delicate appearance in front of Sean at this time.

Sean has not forgotten that two months ago, when he went to find Yuli, she swung a sledgehammer and hit the arm of the Flame Construct Golem...

This can only mean that Sean's body refining and transformation experiment on Yuli was more successful than expected.

Yuli's physical fitness growth rate is very obvious. Although it has not reached the level of breaking 100 points like Sean, it is rapidly approaching to about 40 points, and the subsequent improvement speed is still very obvious.

Sometimes, even without Sean mentioning it, Yuli will take the initiative to come to Sean and look at Sean with a pair of eyes full of special meaning.

Whenever Yuli behaves like this, Sean will conduct body refining experiments on her, and the intensity will be greater each time.

"Although there is still the last step of identification and inspection, all the data are basically consistent."

"What do you think of your carrier ring?" Sean said to Yuli.

As time spent together increased, Sean gradually developed a sense of equality towards Yuli, at least sometimes he would ask for Yuli's opinion.

"I'm quite satisfied. Thank you, Master." Yuli whispered obediently.

Nodding, Sean continued to focus on the black ring in the translucent hatch in front of him.

In order to make this black ring, Sean spent a lot of money.

In addition to the rare materials and magic coins, in order to increase Yuli's soul resonance, Sean also melted the soul metal he got from the sea lizard tribe.

The final result is gratifying, and all aspects of the data have reached the standard.

And perhaps because of the addition of soul metal, the black ring made by Sean has another function compared to the mermaid Eliza's habitat necklace - warming the soul.

"Then let's try it next. If we can really put you into the space-type equipment, our next goal in the black domain will be more."

"At the same time, safety will be greatly improved." Sean said.

Yuli nodded and respectfully followed Sean to an open place for experiment.

Originally, the black ring that Sean made for Yuli was intended for bracelets and armbands.

But after arriving at the experimental site, Yuli took the initiative to ask to wear it around her neck.

Yuli's neck is relatively slender and her figure is also very perfect.

However, such a ring that should have been worn on the wrist was actively asked to be worn on the neck by her, which undoubtedly made her feel obvious tightness and breathing depression.

What surprised Sean was that the tightness and breath suppression did not make Yuli feel uncomfortable, but gradually excited her, including the various values ​​​​feeding back from her body.

This situation made Sean stunned.

After being stunned, Sean lowered his head and thought, is this also the effect of the Mirachi Soul Book?

"If you want to use it as a collar, I think you can modify it a little bit." Sean said, touching his chin.
