"Integral of unary functions, ordinary differential equations, analytic geometry of space, differential calculus of binary functions, you should be able to read these in the evening. ”

"Double integrals, infinite series, you can slow down a little ......"

Xu Feng opened the pages of advanced mathematics and continued to study.

The plan is to read the whole book and then start doing the question bank.

However, often the plan can't catch up with the changes, and Xu Feng feels a little troublesome after reading the chapter on ordinary differential equations.

The specific situation is that he memorizes the content of the book, but as soon as the topic changes too much, Xu Feng will feel very tricky, and it will even take a long time to solve.

It's like the problem that Mengyun Annihilation solved for him during the day.

"This feeling is so familiar!"

A memory of the predecessor's learning the formation surfaced.

Xu Feng seemed to have come to the Yanghe Star Zixia Sect thousands of years ago, studying one basic formation after another.

At that time, there seemed to be a difficult problem involving the blending of shadows in the stacked arrays, and the calculation of the interaction between them.

In this regard, the predecessor is very tangled in calculation, time-consuming, labor-intensive, and mental, and even after becoming the Supreme, it can only rely on strong spiritual power to calculate.

Xu Feng looked at the formula in the book and smiled faintly.

With these, you don't have to worry about confusion or explosion when you lay out the formation in the future.

When Yang Hexing's predecessor arranged the twelve overlapping formations, it was a shadow calculation error, which caused him to fall into the formation and be trapped in the formation for fifty years.

almost became a formation master who was killed by his own formation.

This is as ridiculous as the alchemist being killed by his own Dan furnace.

"Don't worry about it in the future, it can be regarded as smoothing out your past obsession. ”

Xu Feng smiled faintly, and there was a shock in the depths of the sea, and the Purple Lake expanded by three thousand miles in an instant.

At the same time, Xu Feng could clearly perceive the enhancement of his divine soul.

Surprise!

Xu Feng entered the bathroom and took a shower.

Change into crisp clothes.

With a wave of his hand.

Dispel residual odors in the living room.

This is a small spell obtained after cultivating the Purple Qi Void Spirit Technique.

Although it will consume a little mana, it will be dispelled directly in order not to cause accidents.

With the continuous improvement of cultivation and qualification, the filth of each breakthrough is less and less, and it tends to be the legendary flawless Dao body.

In the Dharma Transmission Hall of the Zixia Sect, there is a book of the "Ten Thousand Bodies Codex" that records all the qualifications of the immortal cultivation world.

It is recorded in the book that the Flawless Dao Body is a Dao body born in the land of the end of the law, and it requires monks to continuously improve their qualifications in the land of the end of the law to achieve it.

When the predecessor saw this paragraph, he purely thought that this book was nonsense, but as his cultivation became more and more profound, and he saw more and more physiques, he paid attention to this "Code of Ten Thousand Bodies".

Even the predecessor once had the idea of creating a new Dao body with his own blood.

The Immaculate Dao Body is under consideration.

It's a pity that there is no existence in the end world in the cosmic direction where Yanghe Star is located, so the experiment can only be shelved.

Now, by mistake, the soul of the predecessor of Yanghe Star and the predecessor of the earth were unexpectedly fused, and the newborn Xu Feng was not far from becoming a true flawless Dao body in his unconscious cultivation.

Zhuge Xun, Di Yuanshuo, and Mi Gang carried them into the living room in large bags.

"Xu Feng, these are yours!"

The three of them sent the largest bag to Xu Feng.

"This is a few of the brothers' carefully selected snacks for you, don't dislike it. ”

"Thank you. ”

Xu Feng accepted it and took out a bag of peanuts, fragrant, sweet, and spicy, this is a mutated variety of Martian peanuts, which is deeply loved by foodies.

"It tastes good. Xu Feng nodded.

"Advanced Mathematics...... Have you started previewing so soon?" Zhuge Xun took a step back.

"There are so many advanced math exercise books...... Di Yuanshuo took a deep breath.

"Awesome!" Mi Gang only had two words.

"But you're studying here, and our passion for playing games won't affect you, right?"

"It's okay, you guys are free. ”

Xu Feng ate peanuts, which tasted very good.

College life has officially begun!

Xu Feng, who got the new book, was immersed in learning and forgot everything.

On weekends, Xu Feng would leave the university and return to the beach house to continue his cultivation.

Unconsciously, a month has passed, and Xu Feng clearly perceives the bottleneck.

After the breakthrough, it is the sevenfold pulse.

After the sevenfold pulse is reached, the human veins, earth veins, and heavenly veins in the body will be opened one by one, and finally the one hundred and eight veins of the whole body will be opened, reaching the ninth level of the Chong Pulse Realm.

Begin!

Xu Feng ate the purple-patterned three-grade vermilion fruit and settled in the spirit beads arranged by the lower-grade spirit stones.

The Purple Qi Imperial Void Spirit Technique was running rapidly, and the spiritual energy of the Spiritual Qi and Zhu Guo was injected into the dantian, rushing into the Purple Mansion and swimming around.

The six vigorous human veins appeared in the divine consciousness, and the deep and heavy six earth veins appeared, and the six heavenly veins of the mysterious and mysterious revealed their traces.

The purple qi accumulated in the dantian vibrated again, turning into Tai Chi Yin and Yang, and rushed into the first human connection in a silent way, followed by the second and third......

"I see. ”

Xu Feng's heart was unwavering, and he understood many things that he hadn't figured out in his predecessor.

Just when Xu Feng was impacting the realm, an uninvited guest came to the beach villa.

"Boss, what you said is true, no one lives here?"

"Yes, the boy who lived here before has already moved away, otherwise I will bring you here?"

"Isn't that nothing?"

"Idiot! I mean the people are gone, but the things are still there, let's move some back casually, and we don't have to worry about money for the rest of our lives!

"We listen to the boss!"

The man at the head was the first to climb over the spiky wall.

A gust of wind blew, and the flowers in the villa moved.

The man frowned, urging the remaining six to hurry up.

"Boss, the grass over there seems to have moved. ”

"Don't care, it must be some kind of hare, I haven't seen a dog in this villa. ”

"Boss, you have a pair of eyes. ”

The timid fat man pointed to the steps not far away.

The black cat sat gracefully on the steps, staring at them with an unkind gaze.

"Boss, there is something wrong with this cat, the old family said that the place where there is such a cat is unknown. ”

"It's just a wild cat, afraid of a bird?!"

The man rushed forward.

"Hah!"

The black cat on the steps is gone.

"Look, just scare away, I guess where the wild cat came from. ”

"Boss ......"

"Fuss......

The man wiped his face, slimy blood......

The black cat struck its claws, like an elf in the night, and quickly attacked the rest of the people.

"Kill this wildcat!"

The man was furious, and seven people began to round up the black cat.

But their speed is too slow compared to the black cat, too slow.

In less than three rounds, you will be deserted and escaped!

"Ahh

"Run!"

The black cat returned to the steps, sat down for a moment, and then gracefully turned and entered the darkness.

......

This time the breakthrough went very well.

Xu Feng woke up in the early morning of the third day, successfully opened up the human body's leyline, and was promoted to the eighth level of the Chong Pulse Realm.

"If you fly against the wind, how beautiful is it to look down on the world......"

The phone rings.

The number is unfamiliar.

Who is it?

"Hey, Xu Feng, Xu Feng, please come to the Fourth Hospital, his condition has suddenly deteriorated!"

"Okay, I'll come right over. ”
