"The last step."

Chen Yuan poured the fusion solution of eighteen kinds of medicinal materials into a test cup specially designed for heating.

After shaking it for a while to confirm that it was even, I came to a machine with a flame logo on it, opened the hatch, put the fusion liquid into the machine, set the time, turned on the switch, and waited for the heating to complete.

"Based on the concentration and properties of the mixed solution, it takes about four minutes to heat it to the boiling point. The best time to take it out should be about 3 minutes and 55 seconds."

"I have to put it in the 'cooler' within 10 seconds, which means I only have a few seconds left."

Chen Yuan held his breath and concentrated, his eyes fixed on the stopwatch on the light screen in the sky, not daring to relax for a moment.

Time passes minute by minute.

"3 minutes and 53 seconds...3 minutes and 54 seconds...3 minutes and 55 seconds...!"

Chen Yuan picked the right time, immediately opened the hatch, grabbed the test cup, stepped in front of the "cooler" in three steps, put the test cup in, and closed the door with a "bang". The whole process was just

It took just 3 seconds.

"call……"

Only then did Chen Yuan feel the burning sensation coming from his palms. He couldn't help but twitching at the corner of his eye, "Mmp, isn't it a virtual device? How come the feeling of hot hands can be simulated so realistically?"

Fortunately, he put the test cup into the cooling equipment as soon as possible.

"The whole process takes 15 minutes."

Not long after, Chen Yuan heard the sound of "beep, beep, beep" coming from the cooler, and he couldn't help but be filled with anticipation: "I have practiced countless times in the past three years for this moment. No matter what, I must succeed...!"

"

15 minutes passed in the blink of an eye.

Chen Yuan slowly opened the door of the cooler, took out the "test cup", looked down, and his eyes suddenly lit up.

"That's great. The quality of this 'original solution of power' is higher than any experiment I've done before!"

He suppressed his excitement, took a deep breath, and placed the "test cup" on a "scoring instrument" on the table. After a while, he saw the green light on the "scoring instrument" light up and a clear voice sounded.

Complete the entire laboratory:

"Candidate: Chen Yuan

Test sample: Original liquid of force

Operating time: 36 minutes

Sample purity: 95%

Score for this item: 14 points.

"Haha, the purity actually reached 95%, which is much better than I expected!"

Seeing his achievements, Chen Yuan was overjoyed.

In the school laboratory before, he could only refine the "Original Liquid of Power" with a purity of 90% at most. Unexpectedly, during the college entrance examination, he performed exceptionally well.

I haven't been happy for a few seconds. Suddenly, I heard a soft "beep" in the laboratory, and a voice boomed in my ears: "This is the end of the first simulated medicine refining test of the College Entrance Examination Liberal Arts Practical Examination, and the system is being created."

Simulated weapon refining scene, please wait..."

"Is it seamless...?"

Chen Yuan was stunned for a moment, then a smile appeared on his face, "Okay, next level - weapon refining, here I come."

In an instant, the huge laboratory scene began to distort slightly.

Medicinal ingredients, raw materials, tables, and rows of machines began to blur and then disappeared.

With a "ding" sound, Chen Yuan's eyes suddenly lit up.

A very metallic "refining laboratory" appeared in front of you.

Looking around, you can see equipment "components" and smelting equipment that are shining with metallic luster and floating in the void. They are much higher than the refining room in Linjiang No. 3 Middle School.

Before Chen Yuan had time to appreciate these modern refining equipment, a new exam goal appeared in front of him:

"Within one hour, assemble the 'equipment components' in the laboratory into a complete embryo of 'psionic equipment' and complete the refining through the smelting furnace. Full score: 15 points."

"Assembling it happens to be my strong point." Chen Yuan smiled confidently.

Compared with "refining medicine", his "weapon refining" technique is even better. Although it is not perfect, he is ranked second in Linjiang No. 3 Middle School, and absolutely no one dares to be ranked first.

He came to the center of the laboratory and looked at the "equipment components" floating around. Instead of rushing to start assembling, he held his chin with one hand and patiently analyzed: "These components in front of me are obviously disassembled from several different pieces of equipment.

If you want to assemble a complete psychic equipment embryo, you must first classify the existing components, and then select the components of the same piece of equipment for assembly."

"According to the scoring standards of the college entrance examination, the more complex the component structure of psychic equipment, the higher the score. If you want to get a high score, you must choose a piece of psychic equipment with the most complex component structure for refining."

Thinking of this, he stopped delaying.

Concentrate immediately and perform simple calculations and classifications on the components floating in the air.

Fifteen minutes passed, all the components had been classified, and the idea gradually became clear.

"Judging from the existing components, the simplest structure is the 'Level 1 4-star' psychic spear embryo, which requires a total of 68 components. The most complex is the 'Level 1 8-star' psychic armor embryo, which requires 162

block components, the difference between the two is more than double.”

"According to my current level, it shouldn't be a problem to refine a level 1 8-star 'psionic armor' embryo."

After saying that, without thinking, I walked directly to the pile of classified "equipment components" and started assembling them.

The "simulated weapon refining" of the college entrance examination is different from the real "weapon refining".

The real process of refining requires polishing the "equipment components" one by one, then splicing the polished components together, and finally using modern scientific methods to mold them into shape, and then go through multiple high-end processes before casting them.

A complete piece of psychic equipment.

The "simulated weapon refining" of the college entrance examination is a simplification of the weapon refining process, omitting many processes and directly assessing the candidates' "assembly" and "refining" abilities.

Thanks to three years of continuous accumulation and practice in high school, Chen Yuan's assembly process went smoothly.

First divide the 162 components that make up the "Psychic Armor" into four different parts A, B, C, and D, then splice each part one by one, and finally assemble the spliced ​​parts together.

Twenty minutes passed, and a complete "Psychic Armor Embryo" had been assembled.

As soon as Chen Yuan looked at the time, he immediately put the assembled "equipment embryo" into the "smelter" next to it.

He slowly turned the knob to adjust the time accurately, and then stood aside, waiting for the sample to be refined and formed.

"10 seconds...9 seconds...3 seconds...2 seconds...1 second, it's done!"

Ten minutes later, a "beep" sounded, and the "Level 1 8-star psychic armor embryo" was completed.

Chen Yuan couldn't wait to open the smelting device, took it out, checked it up and down, and placed it on the "scoring instrument" in the center of the laboratory.

In an instant, the green light turned on again, and a loud voice came:

"Candidate: Chen Yuan

Test sample: Level 1 8-star psychic armor (embryo)

Operating time: 52 minutes

Sample completion: 98%

Score for this item: 15 points (max)”

"Haha, I actually got full marks." Chen Yuan was overjoyed, "Now let's look at the last item, 'Spirit Refining'."

Among the three major items of the "Practical Examination" of the College Entrance Examination, "Refining Spirits" is recognized as the key and difficult point.

In today's world, most of the "spiritual equipment" equipped by "new warriors" have undergone multiple "spiritual refining".

That is, through modern technology, the aura of heaven and earth is infused into psychic equipment to enhance the various attributes of the equipment.

The more times the spiritual equipment has been "refined", the higher its power and intensity will be. Once the "refining" fails, not only will the previous refining effect be completely lost, but the original equipment will also be damaged.

Different from real "spiritual refining", the assessment method of the college entrance examination is to infuse the spiritual energy of heaven and earth into virtual psychic equipment through the traction of "manpower", and the final score of the candidates is determined by the number of successful "spirit refining".

Compared with "technological spirit refining", "manpower refining spirit" is more difficult.

It not only tests the candidate's ability to draw and absorb spiritual energy, but also tests the candidate's ability to control and use the spiritual energy in the body.

"It's the last level, so you must go all out and do your best to get a high score."

Chen Yuan had a determined look and clenched his fists.

In the blink of an eye, the "equipment embryos", "equipment components", "smelters" and other objects in the "Item Refining Laboratory" all disappeared.

Instead, there is a broader virtual space.

The background color of the space is pure white, which makes it appear elegant at first glance.

Looking forward, a "Psychic Long Sword" was suspended in mid-air, emitting a faint blue light.

A voice sounded again: "Within one hour, 'refining' the level 1 psychic long sword provided by the system 4 times. 5 points will be added for each success and 2 points will be deducted for each failure. The full score is 20 points."

"The full score of 20 means that you must refine the spirit +4. If you fail once, you will regress to the spirit refinement +0. If you want to get full marks, you have to succeed four times in a row." Chen Yuan looked at the psychic sword in mid-air.

, thoughtfully.

The probability of "spiritual refining" is explained in detail in high school textbooks.

Taking level 1 psychic equipment as an example, the success rate of spiritual refining +1 is about 90%.

At Refining +2, the probability drops to 60%.

And with Spirit Refining +3, the probability of success suddenly drops to 30%.

By analogy, the probability of soul refining +4 is only a pitiful 15% or less.

An excellent "Spirit Refiner" can use modern technological means and high-quality auxiliary materials to greatly increase the success rate of soul refining and at the same time prevent damage to equipment when the soul refining fails.

But in the college entrance examination examination room, there is only one requirement for candidates, which is the ability to control spiritual energy.

Replace technological equipment with the body, and infuse spiritual energy through the body into the psychic equipment.

In the past, Chen Yuan relied on equipment to "refining spirits" in the school's laboratory. This was the first time he relied on "pure human power" to "refining spirits", and he was full of expectations.

Controlling "himself", he walked step by step towards the "Psychic Sword" in the void. He gently raised one hand, and with a "boom", a virtual vortex of spiritual energy immediately appeared on his palm.
