Flying snow, taking pictures, cold light flashing on the armor.

Under the command of Liu Yun, the 600,000 troops of the Great Sui attacked the last gateway of Dayu in three ways at the same time, Gukun Pass.

Although there is desperate resistance from the Dayu army and people, the Great Sui army is too strong.

In just five days, they broke through the three villages of Gukun Pass.

The general Xiahou Shang shot Wen Yuan, the main general of Chongma Village, with one arrow, killed the six-rank martial artist with one knife, and killed more than 100 people by himself.

The Wenjia army of Chongmazhai fought to the death and did not retreat, and finally all of them died in battle.

The sound of fighting pierced the sky.

Only the youngest son Wenwu was spared, and he fled into Dingguan Village with his horse and passed the news of the enemy.

Three days later, 30,000 Great Sui Iron Cavalry broke through Dingguan Village.

The youngest son, Wenwu, died in battle.

No one in Dingguan Village surrendered, and all of them died in battle

On the fifth day, in the face of the death battle of the Dayu soldiers, the Great Sui broke the three villages.

When the news broke, the whole country was shocked.........

"Old Niu, this alchemy is really an esoteric knowledge."

Li Ping'an said with emotion.

"Moo~"

The old cow nodded.

It's too hard, it's just too hard~

Feng Yangzi left, leaving all the books on alchemy in this room to Li Ping'an.

Li Ping'an and Lao Niu studied it without sleep or food.

Basically, the door is not out, and the second door is not stepped.

I don't know anything about the situation in the outside world.

At this moment, Li Ping'an was holding an ancient scroll, and there was an alchemy furnace in front of him.

There is also an incense burner on the side, and incense is burning in the stove.

Light smoke curls, shape, fragrance, color, taste intertwined, has a unique charm.

Li Ping'an held this ancient scroll in one hand and a bowl of soy milk in the other.

Break the freshly fried fritters into several pieces and put them in the soy milk.

Eat and watch.

From time to time, I also found a few soybeans as a snack.

"Old cow, old cow!"

Li Ping'an walked out and saw that the old cow was teasing the neighbor's heifer.

Hey~

A backflip, and suddenly the neighbor's heifer looked at the old cow differently.

"Moo!!"

The old cow wagged his tail triumphantly.

"Old Niu, stop playing, come back and get down to business."

"Moo."

The old cow quickly ran back and handed Li Ping'an a bottle of fresh milk shyly.

"Moo~"

It's just squeezed, but it's delicious.

Li Ping'an: .............

"In the future, we won't do this kind of thing to take advantage of other people's heifers."

“.... Well, but the milk is delicious. ”

The old cow smiled proudly.

Back in the alchemy room, Li Ping'an gave an order, "The old cow is on fire." ”

"Moo!"

Li Ping'an opened the first page of the small book.

The first knowledge point, the most important purpose, the most important function and the most important significance of alchemy, is to purify and retain the ingredients of its medicinal substances.

And make it combine with the newly infused aura as much as possible to form as much of the high-value "medicinal aura" as possible. ”

As for the "harmless and useless substance components", whether they should be eliminated completely, partially, or not at all.

These are all knowledge points, and they should be decided according to the specific situation.

It's like a math problem, you can't just apply a formula, but you have to analyze it on a case-by-case basis.

The old cow made a fire.

The core of the alchemy furnace is "Danhuo", and Danhuo is not simply "fire".

It is produced in "earth and stone" and has the attribute of "gold", so it can overcome "wood" and liquefy elixir.

"Huhuhu~"

One person and one cow are busy.

Lao Niu is responsible for controlling the fire spirit fan, inputting spiritual energy, fanning the fan, and regulating the intensity of the Danhuo.

Li Ping'an opened his eyes.

【Breath Lock】

The divine consciousness is injected into the Dan furnace, and you can "see" the situation of the elixir in the Dan furnace.

Use the divine sense to detect and classify the components of the liquid medicine, and discharge the inactive ingredients.

Or transfer the active ingredient of the liquid medicine to the isolation chamber.

For different levels of alchemists, the strength of his divine sense must be different, and the stronger his divine sense.

The more accurate the grasp of the liquid medicine, the more accurate the judgment of when the step of "infusion and transformation" is completed, the higher the grade of the elixir.

The sun goes down and rises again.

Li Ping'an and Lao Niu seemed to be frozen by time, and they didn't dare to be careless.

Three days later.

Baked!!

The old cow stared.

When the elixir was baked, Li Ping'an and Lao Niu checked it with apprehension.

Well, not bad, not bad.

The corners of Li Ping'an's mouth were slightly hooked, and the books of these days were really not read in vain.

Although there are still many impurities in the pill, this is already a great improvement for Li Ping'an.

Time will leave the rest.

"Bang bang!!"

At this time, there was a knock on the door outside.

The person who came was a slender young man.

"Excuse me, is this Mr. Feng Yangzi's residence?"

"Yes." Li Ping'an nodded.

The young man arched his hand, "I am here to apprentice to Mr. Feng Yangzi, this is the name of the next place." ”

"Apprentice? Mr. Feng Yangzi has gone to the battlefield. Li Ping'an said.

"Huh?" The young man was stunned for a moment, ".... Then Mr. Feng Yangzi can say when he will return? ”

"No, you tell me an address, and I'll let you know when he comes back."

"Thank you very much."

Li Ping'an closed the door, took the young man's name card, and couldn't help but smile.

The world is chaotic.

Dayu's capital is also not peaceful, and sometimes there are people who take the opportunity to make trouble.

There are also some spies who have long been planted in the capital of the Great Sui, taking the opportunity to make trouble.

At night in the capital, you can always hear the noise.

Even some of the officials who patrol the streets are often attacked.

Not to mention the ordinary people who are powerless.

The late-night wind brought a shrill shouting in the distance, mixed with the sound of the wind and the screams that came out of nowhere.

Darkness covers sin.

A flock of pitch-black crows suddenly emerged from the darkness and hovered overhead.

Bang la la la la~

In the dim moonlight, the cold wine that had just been taken out flowed out and poured into a bowl.

Li Ping'an and Lao Niu sat on the steps, smashing the wine unhurriedly while eating barbecue.

"Old Niu, do you think Da Sui can win?"

"Moo~"
