If I kill ghosts, I will become stronger: Invincibility starts with breathing

Chapter 375 The effect of dense fog and gray gas on the brain

At seven o'clock in the morning on September 9th, Lu Yao returned to the dormitory after eating breakfast.

At this time, there are only two days left before the assessment time.

After returning to the dormitory, Lu Yao took out an advanced blood coagulation pill and swallowed it.

Then he closed his eyes, sat cross-legged on the ground, and started the impact of the meridians.

What he is attacking now is the second meridian.

After persisting for about 51 minutes, Lu Yao felt nauseous. He knew that his body had reached its limit, so Lu Yao opened his eyes and stood up.

"The bottleneck period of the second meridian has loosened almost to [-]%." Lu Yao thought to himself.

"There is still the last gray air current in the state of thick fog left in my dantian."

"Even if the power of qi and blood absorbs this gray air current in a dense fog state, it will still be impossible to complete the breakthrough of the second meridian."

"I simply let my brain absorb this gray air current to improve my memory, comprehension, and comprehension."

"When I get to the refining training ground, I will absorb this gray air current."

Then he practiced the water source combat skill again, and then left the dormitory to go to the refining training ground.

When he arrived at the training ground, it was only 8:25 in the morning, and he did not immediately start building weapons.

He sank his consciousness into the dantian, and began to control the last gray airflow in the dantian, allowing the gray airflow to slowly approach the brain.

When the gray air is about to approach the brain, the brain instantly absorbs the gray air.

Lu Yao instantly felt that his memory ability, comprehension ability, and comprehension ability had been greatly improved, and then countless scenes began to flash in his mind. He felt that he seemed to be able to control his thinking and understanding. Power, comprehension.

It seems that the subconscious mind already knows his current appeal.

The scene that appeared in his mind was exactly the scene where he built human-level weapons before.

He felt as if his brain had turned into a high-speed computer, and he began to constantly calculate the steps that he did not do well in the process of building weapons, and even the steps that needed to be optimized in the process of forging weapons in the future .

"It turns out that the strength of the tempering is not uniform enough. I need to control the strength more evenly. The degree of calcination is not enough, and the temperature control needs to be higher." Lu Yao looked at the casting scene in his mind, and found a lot of things to do at once. Not good enough.

He has a new understanding of the entire casting process.

These scenes only flashed for a few minutes, but Lu Yao felt that his casting level seemed to have increased significantly.

Lu Yao opened his eyes, and now he has a better understanding of the gray air current in the dense fog state.

"It turns out that the gray air current in the dense fog allows me to comprehend and optimize a certain kind of skill in a fixed way. It can be refining medicine, refining equipment, or even combat skills." Lu Yao thought in his heart.

"And the degree of this kind of comprehension is dozens of times stronger than the gray gas in the mist state."

"I'm more confident in casting human-level weapons now!"

Originally, he only wanted to build a stepless high-grade casting furnace, which he would use when he returned home.

Although he is now able to forge low-level human-level weapons, the difficulty of forging furnaces is much greater than that of weapons of the same level.

He was built without confidence.

And now after absorbing this gray air current, he has strong confidence in himself.

He put the two mineral materials into the casting furnace at the same time, and then began to output his blood power.

The ground fire in the casting furnace was ignited, and the temperature began to rise.

Because he has more confidence in his casting level, he used to put two kinds of mineral materials into the casting furnace in batches, but now he puts two kinds of materials at the same time.

This time he is going to build a human-level quality casting furnace.

Under the control of high temperature, the two materials are rapidly softened by calcination.

When the calcination reached a certain level, Lu Yao took out two kinds of mineral materials, and then raised the casting hammer in his hand.

The power of his qi and blood instantly merged into the casting hammer, and a layer of blood-colored air was wrapped around the periphery of the casting hammer.

With the blessing of Qi and blood, the casting hammer can exert a stronger striking power.

It may be because another gray airflow was consumed, and unlike the gray airflow in the mist state that was consumed before, the gray airflow in the thick fog state this time seems to be able to optimize the knowledge content of a certain memory scene .

This made his entire process of casting human-level weapons optimized.

And now the consumption of mental power has become smaller, and the ability to control qi and blood has become better.

When casting weapons in the past, there were still some doubts about how to output the power of energy and blood during the casting process, and how high the temperature needed to be controlled in each time period.

Now he seemed to have confidence in his heart.

"Boom boom boom!"

"Dong dong!"

Lu Yao kept beating the two mineral materials. During the beating process, the impurities in the two mineral materials were quickly removed, and they were also slowly fused.

After the temperature of the materials cooled down, Lu Yao would also put the two materials into the casting furnace to continue calcination.

Then continue to beat.

The process of calcination and hammering is repeated several times until the weapon takes its shape.

When building a human-level weapon before, although I already had a design plan in my mind, I already knew what the weapon should look like.

But it may be because the casting material is harder and tougher, it is more difficult to make the weapon into the ideal shape.

Therefore, the shape of the weapon that is often created is still somewhat different from the shape of one's own imagination.

But now the shape of the weapon that Lu Yao created is exactly the same as the shape of the weapon in his mind.

But at least from the original 5% similarity, it has increased to the current 7% similarity.

After the cast weapon was calcined again, Lu Yao picked up the rune pen on the table and began to engrave the rune combination on the weapon.

The first was the engraving of the first rune combination. He felt that the resistance was getting smaller and smaller, and a burst of white light began to flash, which represented that the first rune combination had been engraved successfully.

He didn't stop, and then began to inscribe the second junior combination.

Another white light appeared.

The second rune combination was also engraved successfully.

"The power of blood and blood is consumed even less, and there is still a lot of power of blood and blood left, so we can complete the engraving of the third rune combination!" Lu Yao thought in his heart.

He didn't stop, and immediately began to engrave the third rune combination.

The resistance of the pen tip was even greater, and Lu Yao increased the output of energy and blood.

Although the inscription with the rune pen was very difficult, it was finally inscribed successfully, and another white light began to appear.

All three rune combinations have been engraved successfully, the most difficult steps have been completed, and the remaining steps have become easier.

Lu Yao put the weapon engraved with the combination of runes into the casting furnace, and continued to calcine it. After the calcination was successful, he took out the weapon, and then output his energy and blood to warm it up.

The steps of calcination and warming need to be carried out more than three times before a weapon is truly formed.

"Successful, I will take this human-level casting furnace home and use it." Lu Yao thought to himself.

Foundry furnaces are divided into portable and built-in.

The built-in casting furnace of the same level is more capable of casting high-quality weapons.

Now the weapons that Lu Yao forged have steadily entered the quality of the primary human level.

"Now I can forge weapons faster. When I first finished casting human-level weapons, it took me more than 3 hours to create a human-level primary weapon. Now I only use 2 It will be completed in 36 hour and [-] minutes." Lu Yao thought to himself.

"If I follow my own progress, I'm afraid it will take more than two months to control the time for building weapons to about two and a half hours."

"And this time, a gray airflow in a dense fog was consumed, which saved me nearly two months of practice."

"It's a pity that the gray gas in my dantian has been exhausted now. I will do more tasks during this holiday and try to collect more gray gas."

"The gray gas in this dense fog state is really easy to use."

"Whether it's improving my refining skills, or the professional level of refining tools, or using it to break through my meridians and improve my energy and blood, they all have very obvious effects."

After the weapon was successfully forged, Lu Yao bid farewell to the teacher and left the training ground.

He didn't go back to the dormitory, it was almost time to eat, so he went directly to the cafeteria of the college to have lunch.

After returning to the dormitory, Lu Yao closed his eyes, sat cross-legged on the ground, and started a meridian shock.

Without the help of pills and gray airflow, he would be able to last about 30 minutes of time impact.

Once more than 30 minutes, he felt nauseous and dizzy.

It's time for the final assessment soon, and Du Tong and Zhan Yu have now entered the bottleneck period of qi and blood before 100 strength.

And Lei Ming and Zhao Dieyi also broke through to the 90 force blood bottleneck period.

Now Lu Yao's level of refining medicine has improved a lot compared to last semester.

The quality of the refined pills is also higher, which makes their energy and blood grow faster.

Now Lu Yao has refined the Ningpo Pill, which is also very effective in breaking through the acquired realm.

This can shorten the time for them to break through the acquired realm.

Lu Yao practiced the water source combat skills for a while, and at 1:25 pm, he left the dormitory and went to the rune classroom.

He was the first to come to the classroom.

He very consciously started the engraving of the primary rune array.

Before, it took him more than an hour to engrave a primary rune array.

But now the effect of the gray air current is still in his mind, improving his memory, comprehension, and comprehension.

Although most of the gray gas effects are used to optimize the steps of casting weapons.

But the rest is enough for him to engrave the rune array map, making it easier.

There is less resistance to the nib and the lines are a little smoother.

It took only 53 minutes and 11 seconds for Lu Yao to successfully engrave a primary rune array.

Then he took out a blood energy pill to replenish the energy and blood power he had consumed.

Then immediately started the engraving of the second primary rune array.

The second time took even less time, that is, only 52 minutes and 50 seconds, and he successfully engraved a primary rune array.

After the two inscriptions were finished, it was already after 3:[-] in the afternoon.

Lu Yao left the rune classroom and returned to his dormitory.

He took out the refining cauldron from the room, ready to start refining the pills.

This time the pill he refined was still Ningpo Pill.

Lu Yao opened the medicine refining cauldron, and then put 6 different medicinal materials into the medicine refining cauldron. After covering the medicine refining cauldron, he began to send the power of Qi and blood into the medicine refining cauldron.

The immobilized rune array was lit up, and the temperature began to rise.

Lu Yao's Qi and blood power was split into six strands, and the output of each strand of Qi and blood power was different.

The six qi and blood forces control six different medicinal materials, and the six medicinal materials are constantly approaching, and the steps of refining and merging are also going on at the same time.

When a cloud of dark green liquid appeared in the alchemy cauldron, it meant that all the medicinal materials had been fused successfully.

Lu Yao once again increased the output of energy and blood, and the temperature inside the cauldron was also higher.

Impurities in the medicinal liquid are being quickly removed, and the medicinal liquid is also rapidly concentrating.

It didn't take long for the liquid medicine to condense into a brown-black solid substance.

Lu Yao's energy and blood split into nine strands, and the nine strands of energy and blood divided the brown-black solid matter in the cauldron into nine equal parts.

Jiufen's solid matter was continuously tumbling in the cauldron, and was finally refined into the shape of a pill.

Lu Yao increased the output of energy and blood again, and the temperature inside the alchemy cauldron reached the highest point. The volume of the pills was slowly shrinking, but the efficacy of the medicine was increasing rapidly.

The sound of explosions could be heard continuously, it was the pills exploding in the cauldron.

Lu Yao still didn't change his expression, he was used to this kind of process.

He also knew that the more critical the moment was, the more he had to keep his peace of mind.

When there is a strong smell of medicine, it means that this time the pill refining has been successful.

Lu Yao stopped the output of energy and blood, and after the temperature inside the cauldron cooled down, Lu Yao opened the alchemy cauldron.

There is a brown-black pill in the tripod, which is the primary Ningpo pill that has been successfully refined.

"This time, it took me 87 minutes and 11 seconds to complete the refining of Ningpo Pill, which is a little faster." Lu Yao thought to himself.

"Ningpo Pills don't need to be refined too much, about 50 or so should be enough for them all to break through to the Houtian realm."

"On the other hand, the two pills, Ningyuan Pill and Ningxue Pill, need to be refined more."

It was already five o'clock, Lu Yao and several partners left the dormitory and went to the cafeteria to have dinner.

After returning to the dormitory, Lu Yao began to attack the meridians again, and then took out the medicine refining cauldron from the room, and continued to refine Ningpowan.

At ten o'clock in the evening, Lu Yao stopped refining the pills.

In more than ten hours at night, he had already finished refining the pills three times.

And the time for refining the Ningpo pill has been controlled at 85 minutes and 21 seconds.
