One month later.

In his residence, Luo Yan was buried in his desk, writing furiously.

Next to him, half of the room was filled with test data from this period, as well as more possible conjectures and verification plans.

The more he wrote, the more painful his expression became. In the end, his eyes turned red with anxiety, like a party who had revised his plan hundreds of times but still hadn't received a pass. He wanted to overturn the entire table.

Why are these array formulas always wrong no matter how I modify them? Luo Yan was so annoyed that he almost wanted to tear his scalp off.

"I told you a long time ago that the previous step shouldn't be calculated that way..." Kunlun Jing muttered beside him.

"Ajing is useless. Even if you change the formula, it's still wrong. The initial assumption is wrong..." Qingping Sword began to argue with Kunlun Mirror.

At first, Luo Yan was in the mood to tell the two voices in his mind to shut up, but now he is left with indifference and ignorance.

Another area in the room, near the door, was turned into a kitchen by Shi Liuli.

As Luo Yan became more and more addicted to doing homework, Miss Shi, who loved food, had to support herself and began to study cooking seriously.

Although I never cooked before, after cooking more, the food I make is no longer inedible.

In addition, Luo Yan's complexion had been visibly getting worse recently, and Miss Shi was worried, so she planned to make some delicious food to take care of him - of course, satisfying her own appetite was only secondary, the main purpose was to reward her hard-working junior brother.

Chop the ginseng and polygonatum into pieces, dice the spatholobi, blanch the beef and put them into the pot together, then add some bay leaves and peppercorns... Shi Liuli closed the pot, admired his work, and clapped his hands with satisfaction.

In the side hall of Guixu Palace, in addition to a large number of books on formations, there are also many miscellaneous books. For example, this magical recipe book that uses various immortal herbs to cook dishes is like a treasure to Shi Liuli.

It would take at least an hour and a half to dissolve the ginseng and polygonatum into the soup and stew the beef until it was well-cooked, so Shi Liuli carefully adjusted the fire-controlling magic weapon and then turned around to play with Luo Yan.

"Junior brother!" She sat down next to Luo Yan, pulled his arm and asked, "Guess what I did today?"

"Dish." Luo Yan didn't even raise his head.

"What dish?" Shi Liuli playfully kept the question in suspense.

Luo Yan ignored her, paused his pen for a moment, and then started writing quickly again.

Regarding the formation model of the Guixu Formation, he suddenly had a brilliant guess, which needed to be quickly calculated and confirmed.

Seeing that his junior fellow apprentice ignored him again, Shi Liuli felt a little annoyed, but managed to hold it back.

Okay, he wants to study the Guixu Formation now, I don’t mind.

Don’t eat a single bite of the beef stew I’m going to have later!

Shi Liuli returned to the kitchen and continued to tinker with her new dish.

Add vegetable oil and butter to a pan and stir-fry until melted. Pour in flour and mix well to increase viscosity.

Then add the soul of this dish - the sauce made from hundred-year-old red fruits. It must be more than a hundred years old, otherwise the taste will be too sour.

Then stir constantly with a spoon and simmer over low heat until the water in the pot is completely dry. Then add water in batches and continue stirring, allowing it to slowly melt, and finally become a pot of delicious, spiritual nourishing soup.

Shi Liuli rolled up his sleeves and swung the large spoon for a long time. He felt his arms were so sore that he simply threw the spoon away, took out his flying sword to wash it, then made a sword gesture with his left hand and let the flying sword circle around in the pot and stir it.

The soup finally turned into a bright orange color. Shi Liuli then raised his sword finger and moved the poor flying sword, which was already in a mess, to fly out of the pot, shake off the soup, and then fall into the bucket next to it.

"Add salt to the soup..." She continued to follow the recipe, "Add wine, and then add scallop powder to enhance the flavor. Um, a small amount of maltose."

"Next, take out the previously stewed beef, polygonatum and ginseng and pour them into the jar."

“Mix the mushrooms and pitted red dates, mix well, and finally pour the soup over them.”

“Keep simmering.”

This time, Shi Liuli decided not to cover the lid, letting the aroma of the stewed beef fill the entire room, waiting for his salivating junior fellow apprentice to come and ask for food.

The rich aroma of the beef and the unique fragrance of various magical herbs began to emanate from the pot.

She washed the rice and cooked it, then folded her arms triumphantly and waited for Luo Yan for a long time, but he didn't even raise his head and was still calculating the formula.

The formation formula is still wrong. The so-called wonderful inspiration has now been proven to be an illusion... Luo Yan was so angry that he wanted to kill indiscriminately.

No matter what they kill, just kill them randomly.

Shi Liuli looked at his back, her expression changed from smug to hesitant, then to confused and bewildered, and finally to furious.

No way, he didn’t even raise his head?

Is it because the beef I stewed is not fragrant? I think it is still quite fragrant...

Hiss!

After swallowing a big mouthful of saliva, Miss Shi decided to confirm whether there was something wrong with her food.

I drank a little of the soup first. Hmm, it was fresh, fragrant and delicious, and also nourishing. It was a delicacy worth trying for those who practice Taoism.

Eat another piece of stewed beef, hmm, it is soft, smooth, tender, and full of soup. It has the aroma of both meat and medicine. The sense of layering can be said to be extremely clear.

So why is my junior brother not interested?

Shi Liuli was thinking while tasting, and before he knew it, he had eaten most of the whole jar of beef.

When she came to her senses, only a thin layer of soup and three or four pieces of beef were left.

She shuddered suddenly and subconsciously looked at Luo Yan guiltily.

After confirming that the junior brother was still absorbed in doing his homework and hadn't noticed them at all, Miss Shi quickly took a small bowl, scooped out the remaining soup and beef, then quickly cleaned the large jar and destroyed all traces of the corpse.

Just after washing it, I heard Luo Yan suddenly throw the pen down.

I really can’t figure it out, I’m not going to do it anymore!

After finally suppressing his frustration, Luo Yan slowly came back to his senses.

There is definitely no answer to this question.

My ability to "understand a thousand things after hearing one thing" has theoretically given me the best understanding in the world.

A problem that even I can't solve must have no answer - that's the only explanation.

Let's eat something. Sigh, I wasted so much time...

Luo Yan stood up to serve the rice, and tasted the soup and beef that Miss Shi had left for him. He immediately praised it highly:

"Senior Sister, your beef is absolutely amazing! The soup and rice are even better. The overall evaluation is like refining a magical medicine into a magical pill. It is almost a qualitative leap..."

"As long as you like it." Shi Liuli said guiltily.

Luo Yan didn't know what she was thinking, or rather, he had guessed it but pretended not to know, and just continued to brush the synchronization value, smiling:

"I see. I understand. You cook beef and spiritual medicine together, right? I didn't expect that such ordinary and plain ingredients could become so delicious after being soaked in the medicinal juice..."

As he spoke, his face suddenly darkened.

Wait, boil the elixir into juice and then soak the beef in it?

Could the so-called Guixu Formation also be... some kind of "juice"?

Seeing his face suddenly darken, Shi Liuli quickly explained:

"The reason why there is only so little left is because I was too hungry just now, and you didn't seem to want to come over for dinner for a long time..."

Luo Yan stood up suddenly, hugged Shi Liuli tightly, kissed her on the cheek, and then rushed out of the room.

Shi Liuli was stunned for a moment, then covered her cheeks tightly.

The body is burning.
