After counting these finances over and over again, Lin Anxin smiled.

Playing with those few second-order crystal nuclei of excellent quality in his hand, he thought that he would have to exchange these things for other materials later.

The demeanor of this guy touching these "treasures" became more and more obscene, like the appearance of the landlord Lao Cai who had accumulated the gold and silver he had accumulated in the middle of the night and slept in the bed.

No way, high-end magic crystal is equivalent to high-end hardware in the DIY market.

The "mining machine" piled up with a large number of low-level magic crystals, although it is not much worse than this high-end goods in terms of performance, but it is not as convenient as high-end goods to use after all.

But if you want to build a huge energy matrix like a sentinel core, and if you want to use a whole piece of pure color magic crystal, it is almost impossible for a fourth-order demonic beast to produce it.

Even if it was a magic crystal that was fully used for second-order demonic beasts, the cost of it was beyond Lin An's current capacity.

Unless...... Unless he doesn't get the Sentinel Armor, but develops a new set of battlefield support equipment that belongs exclusively to Little Tanhime.

A flash of light flashed through his mind, and he suddenly thought of the pair of saucer-shaped amplifiers that the Venerable Archbishop was carrying behind his back, like a shuttle battleship.

This is a device used to amplify the psionic power of the astral spirits, and the mechanical Templars are not afraid of the damage caused to their bodies by excessive psionic energy, so they basically have one each.

Even the little tanji is no exception.

But this thing was originally put on the machine by the star spirits according to the endurance of their own biological form.

With a subordinate unit such as a Sentinel, there is no need to upgrade the device.

But this gave Lin An a completely new idea.

That is to imitate the psionic amplifier behind the archbishop, and make it look like a sentinel armor.

This will somewhat weaken the Sentinel Armor and have a problem with energy supply.

But the all-round robot that could assist a team of people and horses now only needs to serve the combat unit of Xiao Tanji.

Even if he added himself, he wouldn't go beyond the energy cycle provided by this specialized version of the Sentinel Armor.

It can also make the sentry who moves slowly sprint and move with the little tanji's pace.

The advantage of speed and agility on the battlefield is simply not too much!

The most important thing was that in this case, there would be no need for him to take out these second-order magic crystals in excellent condition in his hand to exchange them for money.

Lin An's idea is very similar to that of DIY users who are switching to other cheap accessories for graphics cards and CPUs.

However, there is also a fatal problem that stands in front of him.

That is, if he wants to adopt this solution, he will have to face the risk of failure to upgrade!

Because no matter how similar the principles of the two are, there are no ready-made drawings for him to practice for a complex device of this level.

Upgrading parts for a machine soul is more troublesome than changing a prosthetic limb.

After all, the soul steel can be directly connected to the consciousness of the machine soul, and if the function and model do not fit, it is like a huge sarcoma suddenly growing on the human hand.

It's not just that the upgrade fails, but the material cost of repairing the machine soul beast is also a big expense.

Of course, these forged parts can still be recast, but even if you don't talk about labor costs, the fire consumption alone is enough to make people feel distressed.

Previously, Lin An was based on the ready-made drawings stored in Xiao Tanji's knowledge base, and he made them in a variety of ways, so there were no rejection reactions.

He's not a great mechanical genius, let him transform the crystallization of the wisdom of thousands of star spirit technicians, maybe something will really go wrong.

"Sure enough...... Do you still want to abandon this plan? ”

Imagining the price of failure, Lin An sighed.

Before, like a fool, he sat in the living room and had a long time of silly fun.

Now that he has been knocked down by the ruthless reality, this is somewhat depressing.

Xiao Tanji, who has been busy in the kitchen for a long time, has always felt the inexplicable joy that Lin An passed back.

But when it brought the sumptuous dishes out of the kitchen, it felt Lin An's mood drop rapidly.

In order to find out why his dear master has such a "neurotic" mood that fluctuates in a short period of time.

Xiao Tanji, who had been caring for him, directly popped up a void panel, drawing his own questions with spiritual energy, and asking if Lin An was wrong.

Being completely open to one's own summoner is something that happens to every summoner.

Lin An is no exception, after telling everything in his heart.

Xiao Tanji was on the light screen, and he was very sure that he could optimize the drawings of the fusion sentinel amplifier, but it would take a little time.

Lin An watched in surprise as the little tanji broke away from the guard's armor and returned to the appearance of a little goldfish, floating onto his lap obediently, begging for his touch as if asking for merit.

With deep emotion, he stroked the little Tanji in his arms, like kissing a pet, and nodded on her forehead.

Looking at the delicious food in front of him, as well as the well-organized residence, he breathed a sigh of emotion, and said to the little tanji with relief and helplessness.

"Without you, I'm like a waste~"

Although it was a joke of self-deprecation, Xiao Tanji looked at him with some anger, obviously not allowing his master to have the slightest self-contempt.

Just when the emotions of one person and one machine were infinitely warm, the bell at his door rang.

With the rhythmless triple beats and the violent kicking of the door, Lin An could probably guess that it was Senior Sister Dong who came to visit.

After all, he had just unceremoniously knocked her to the ground in front of everyone.

A little worried about whether his twelve-centimeter-thick armored door could resist Lin An, who was killed by this violent princess, felt that it was better to open the door for her obediently.

With a click, the crunch of the metal lock unlocking came out.

A blonde woman in a short white robe appeared in front of him.

Dong Chan'er's face was still cold, but it was much better than when she was knocked to the ground in the arena.

Lin An didn't know why this woman was in such a hurry to find herself.

The slightly wrinkled tactical robe on her body showed that the woman hadn't changed her clothes since she came out of the arena.

Before he could say yes, the blonde princess broke into his home.

The little tanji, who was still coquettish before, has now returned to the combat state of the battle armor dress.

Even if Dong Chan'er wanted to summon her terrifying dragon blood recklessness here to take revenge, Xiao Tanji was sure to take the first step to let her head fall to the ground.

However, although this Senior Sister Dong is menacing, she is not here to find fault.

After staring at Xiao Tanji, who was slightly hostile to her in the room, after staring at the rich food on the table out of the corner of her eyes, Dong Chan'er turned around and directly stated the purpose of her trip.

"My uncle is pleased with your performance, and he has agreed to my suggestion to put you on the list of expeditions to the sea.

In August and September, after the Phantom Cup, you will go on an expedition with me to join the Ninth Academy's expeditionary force! ”

When Dong Chan'er said the word satisfaction again, her silver teeth were about to be crushed.

Obviously, she still has a grudge against Lin An for throwing her to the ground in the morning.

But this is nothing compared to what she said, Lin An never thought that he could still have anything to do with the Ninth Academy Expeditionary Force on campus.
