The first floor of the ancient building is covered by the building.

The doors of the Spell Lab are locked tightly.

"Bang~"

A slight explosion.

Countless dazzling white sword energy flew around, and the speed was so fast that it could not be seen clearly. It hit the walls around the laboratory and made a series of dull sounds.

Ripples spread out on the walls, blocking them with difficulty.

This laboratory is prepared for students, and the design requirement should be to be able to block spell attacks at level 5. However, the spell progress has been very fast over the years, and Chen Shu's comprehensive spiritual sea abilities are much stronger than those at level rank. It is estimated that when he reaches level 5, this experimental shooting range will be a bit terrible.

Chen Shu stood there, thinking quietly.

As a simulated spell sword energy, its power is already comparable to that of ordinary sword cultivators and martial arts cultivators, and the number is very large. In terms of spell power alone, he can already feel satisfied...

After several days of modification and modification, as well as the guidance of Teacher Shi Qian, its performance should be no less than the master spell of the sword light bullet in his hand.

But the spells used by humans are obviously different from the master spells of shells and grenades.

The environment of the Linghai Sea and the shooting environment are different.

Grenades are thrown out and exploded, and shells are shot out and exploded. They all use themselves as the center of the circle to release sword energy to the surroundings without distinction. There is also a mechanism to allow the sword energy they release to avoid the ground below and target personnel.

If they are to be changed into magic that practitioners learn, they must be modified.

Practitioners must have more refined control over it.

The first thing is to avoid yourself.

Secondly, you must be able to control the direction of the sword energy, and at least choose one direction and not hurt your own people by chance.

Finally, it needs to be transformed from a range attack spell with its own base point to a tracer like a tracer, with a certain range, and can condense the spiritual power and then stimulate the long-range attack of the sword energy.

Then, Chen Shu was a little dissatisfied with its dazzling light.

Looking at the spell runes, we learned that the white light is brought by a rune that constitutes the sword light, rather than given by other runes. Unlike tracer techniques, the light emitted by various tracer techniques is different, but other runes conceal these lights, and new runes determine whether to let it shine. Usually, according to the needs of their own combat environment, the practitioner can choose to make it shine red or not.

This rune in this sword light technique is very important and cannot be replaced. At least Chen Shu does not have the ability to replace it.

Then we can only learn from the rune structure group related to tracer technique and use other runes to hide its light.

Invisible weapons are more powerful.

Perhaps we will continue to optimize it in the future to enhance its performance, such as adding stronger "penetration" capabilities to it, but that should be done after the research on penetrating runes has results.

Chen Shu continued to get busy.

Three hours passed.

The alarm rings.

Chen Shu didn't stop and insisted on completing the first stage

Rune relocation project from tracer to sword light.

Experiment again.

"Bang~"

The invisible sword energy was stimulated again, hitting the surrounding walls, and the dull sounds were almost connected.

Let's go again.

"Bang~"

This time it was bright white sword energy again.

very good.

Can be freely controlled.

Chen Shu breathed a sigh of relief.

He put away the sword light bullet whose spiritual power was basically exhausted, and put on his schoolbag, and opened the door to the laboratory.

"Senior Brother Chen!"

A voice shocked Chen Shu.

The senior brother leaned against the door and rubbed his eyes. It seemed that he had finally waited for him and quickly handed him a cup of milk tea: "Thank you, Senior Brother Chen, drink water and water! Are you finished? Are you still busy? If you are not busy, can you help me see the last set of core runes of my spell?"

“…”

"Senior Brother Chen!!"

"Then let's take a look..."

"Thank you, senior brother!"

When the senior brother saw Chen Shu taking the milk tea, he was so excited that his whole body trembled.

He just wants to trick out a useful impact technique to deal with the upcoming martial arts experience. Those people in the Martial Arts Academy are good at close combat. Knowing one impact technique can keep themselves safe, at least don’t be caught in seconds as soon as they come on the court.

real.

At first he just thought it was OK to use it.

Unexpectedly, I met Senior Brother Chen. After being given guidance from Senior Brother Chen, hey, the power seems to be pretty good.

Later, I spent time in the laboratory and met Senior Brother Chen twice in a row. I changed some core rune groups. This spell has become more and more excellent. It is also more and more in line with my spiritual power level and usage habits.

It's a bit like looking at the computer configuration...

But don't pay!

The senior brother followed Chen Shu upstairs and said as he walked, "There is only this last problem. After the modification, I will not change this spell. If I cooperate with the other small methods I know, I should not lose too badly."

"I wish you a smooth..."

"Haha, thank you, senior brother, you didn't want to get a ranking." Senior brother smiled honestly, "Oh, senior brother! Do you have any experience in applying for martial arts?"

"Reported."

"Come on, senior brother!"

"Thank you... This water is good, where did you buy it?"

"Outside the north gate, the stall selling apricot peel water is next to the fried chicken shop."

"I know."

Chen Shu took another sip, and it was sour, like sour plum soup, but it wasn't. It tasted much different, and it had a faint fragrance of osmanthus, Qingqing must like it.

After helping this senior brother read the magic runes, he spent ten minutes and then walked out of the Gu Xiulou.

It started raining outside.

The spring rain is as thin as silk.

The rain blows and the wind blows, and the peach blossoms outside the building are all red.

The temperature that rose a few days ago also dropped a little. I could have worn short-sleeved shirts in the hottest days, but now I have to wear a coat again.

Today seems to be Qingming Festival.

It's either today or tomorrow, anyway, I've had a vacation.

Chen Shu could use resistance to reject raindrops, but he did not. Instead, he opened an umbrella and walked slowly towards the dormitory area. Sometimes a gust of wind would blow tiny raindrops on his arm, which would make it cool if he missed the fun of walking in the spring rain because of his practice, what a pity.

When I walked downstairs of the dormitory, I saw a little familiar.

Not Huang Batian.

It's Brother Meng.

Brother Meng also held an umbrella, a retro oil-paper umbrella, wearing traditional clothes, fluttering clothes, standing by the peach tree, looking down at the peach blossoms.

Bah! Bah! Bad!

Chen Shu quickly put away his umbrella and walked towards Meng Chunqiu: "Meng Chunqiu, what are you doing here again?"

"Brother Chen?"

Meng Chunqiu turned around and found it was him. He quickly turned his eyes back and pointed to the peach tree and said to Chen Shu: "Brother Chen, look, when this spring rain comes, the peach blossoms on campus fall all over the ground. It's such a pity."

"Are you thinking about poetry again?"

"well……"

"Do you want to post on Moments again?"

"Brother Chen understands me..."

"Flying red is not a heartless thing, it turns into spring mud to protect flowers." Chen Shu said and pulled the corners of his mouth, "Take it and use it as a copywriting."

"This poem is so suitable..."

Meng Chunqiu, who was worried about falling flowers, was shocked in his heart, so beautiful that he couldn't speak.

Meng Chunqiu stretched out his finger, sucked in his breath, and then turned around with a graceful look. Just as he was about to comment with Brother Chen, he saw Brother Chen turning around with an automatic umbrella, so he held it back.

"well……"
To be continued...
