Gao Wu: My martial arts technique has entries.

Chapter 70 Precipitation
After leaving school and returning home, Chu Kuang immediately took out the Marrow Cleansing Classic and the Tendon Changing Classic and began to study them.
He soon discovered the power of these two special cultivation techniques. Although they were not considered peerless techniques, they were much more difficult to cultivate than advanced techniques, as they were used to improve one's physical constitution.

Without exceptional comprehension, it is virtually impossible to successfully cultivate these two volumes of techniques, and the effects of these two volumes are also quite remarkable.

According to the descriptions in the Yi Jin Jing and Xi Sui Jing, as long as one cultivates either of these two manuals to the point of minor success, one can raise one's physical constitution to the fifth grade; to the point of major success, one can raise it to the sixth grade; and to the point of perfection, one can raise it to the seventh grade.

If one were to further break through the limits of martial arts, one could cultivate a ninth-grade root bone; if both were to break through, one could cultivate a supreme-grade root bone.

"Only by breaking through the limits of two major martial arts can one cultivate a top-grade physical bone. No wonder top-grade physical bones are valued by the school."

Chu Kuang murmured slowly, then shook his head slightly.

Of course, he also knew that the current top-grade root bones were different from the top-grade root bones of ancient times.

When human civilization first embarked on the path of cultivation 100,000 years ago, the innate qualities of ordinary people were defined as Grade One, and then the quality of innate qualities was continuously classified in this way.

At that time, those with fourth-grade physical talent were one in a hundred, and those with seventh-grade physical talent were one in ten thousand, and were known as the best physical talent.

However, as time went on, the number of martial artists in human civilization increased, and the average martial arts talent of new humans also increased.

In this day and age, first and second grade root bones are extremely rare. Normal human root bone aptitude starts at third grade, and seventh grade root bones can only be considered as one in a hundred elites, no longer qualified to be called geniuses.

Therefore, later human civilization redefined the levels of innate talent, not only removing the "top-grade" title of seventh-grade innate talent, but also adding eighth and ninth-grade innate talent, and then adding a "top-grade" innate talent above them.

Later on, even top-grade root bones weren't enough, so they added earth-grade and heaven-grade root bone aptitudes.

There's no way around it; some newborn humans have cellular activity levels that are almost inhuman, and the term "top-tier innate talent" is no longer sufficient to describe them.

Perhaps one day, as the talents of new martial artists in human civilization grow stronger, a divine or saintly talent might be added above the Heavenly Rank.

"The Yi Jin Jing and Xi Sui Jing are just martial arts. The fact that they can elevate a person's talent to the highest level is already astonishing in Earth's era."

Chu Kuang whispered that he had read a brief history of the martial arts era on Earth. At that time, the innate talent of the entire human civilization was estimated to be no more than ten people who could reach the current top-grade innate talent standard.

In this context, the Yi Jin Jing and Xi Sui Jing, which could grant people exceptional physical attributes, even if they were only the unoptimized versions, would certainly have been considered unparalleled martial arts at that time.

With this in mind, Chu Kuang put aside his distracting thoughts and began to diligently study the Yi Jin Jing.

The Yi Jin Jing is extremely difficult to cultivate, but with the boost of ten times the speed of external martial arts cultivation, Chu Kuang did not feel too much difficulty in comprehending it.

After about half a day, he finally grasped the basics of the Yi Jin Jing and then completed his practice with the help of the Nine-Bend Lingzhi.

The same applies to the Marrow Cleansing Classic. Chu Kuang spent about half a day comprehending it, and after refining the thousand-year-old Xuan Shen, he finally mastered its cultivation.

Yi Jin Jing: An ancient Buddhist secret external martial art that can cultivate Yi Jin strength, possessing the wonder of changing tendons and bones, and can improve a martial artist's physical aptitude. Later, after being deduced by the intelligent brain Tai Chu, its effects far surpassed its original state. Attached entry: [Yi Jin]

The Marrow Cleansing Classic: An ancient Buddhist secret internal energy cultivation technique that can cultivate marrow-cleansing internal strength. It possesses the wonder of cleansing tendons and marrow, enhancing a martial artist's innate talent and physical attributes. After ten thousand years of refinement, its effects far surpass its original state. (Attached entry: [Marrow Cleansing])

Yi Jin Jing [White]: Changing tendons and bones, cleansing hair and washing marrow. The aptitude improvement brought by Yi Jin Jing is increased by an additional 10%, and external martial arts talent is increased by an additional 10%.

Marrow Cleansing [White]: Cleanses the tendons and marrow, transforms the body and bones. The aptitude improvement brought by the Marrow Cleansing Scripture is increased by an additional 10%, and the internal strength talent is increased by an additional 10%.

"While improving aptitude, it can also enhance internal and external martial arts talent?"

Chu Kuang murmured, a thoughtful expression creeping onto his face.

Compared to physical attributes, which can be directly measured, talent is something that is much more mysterious and elusive.

For example, combat talent is an absolute consciousness and instinct, which is difficult to detect intuitively through various means, but talent is absolutely real.

With the same physical constitution and practicing the same external martial arts manual, some people make rapid progress while others struggle. This is the difference in talent for external martial arts.

"My talent in both internal and external martial arts should only be at an above-average level."

"With continuous improvement of these two volumes of cultivation techniques, this should be able to make up for this shortcoming," Chu Kuang murmured, then slowly calmed his mind and began to continue his cultivation journey.

For the rest of the time, Chu Kuang no longer needed to go to school every day.

At his level, there's not much that high schools can teach him anymore. Even if you find a martial artist who has mastered the Copper Armor Technique to perfection, the effect will most likely not be as good as the teaching videos of Venerable Tianhuang.

So, instead of going to school, Chu Kuang spent three hours a day attending classes in the martial arts space, five hours fighting in the training ground, and eight hours practicing martial arts in the martial arts room.

With the remaining eight hours, besides sleeping for seven hours, he also spent an hour teaching Chu Yu and Lin Shuya. Even nine-year-old Li Nier remembered these moves.

Although he can't practice them yet, memorizing these moves will greatly speed up his martial arts learning in the future.

As time went by, a month passed in the blink of an eye, and it was time for the first-year high school students' final exams.

"call--"

That morning, Chu Kuang completed another training session.

Chu Kuang finished his cultivation, took a slow, deep breath, and then sensed the panel in his mind.

Name: Chu Kuang

Race: Terran

Hit Level: 8.3

Physical constitution: Medium [Rank 6]

Comprehension: Superior [Rank 7]

Constitution: Ordinary

Realm: Unity of Inner and Outer Self [Mysterious Iron Body] [Majestic Realm]

功法：铜甲功【大成97%】、铜钟罩【大成91%】、易筋经【小成4%】、洗髓经【小成3%】、不死七印【第一印（大成99%）】。

Martial Arts: Mountain-Suppressing Fist [Perfect], Mountain-Suppressing Fist [Mastery 52%], Heavenly Flame Spear [Mastery 85%]

Movement Techniques: Bloodbath in All Directions [Second Level (Mastery 66%)], Thousand-Pound Formation Breaking [Second Level (Mastery 60%)].

"The improvement this month has been tremendous."

Chu Kuang murmured, a slight smile appearing on his face.

Over the past month, he has perfected the Zhenshan Fist, the first level of the Qianjun Pozhen, and the Tongjia Gong and Tongzhong You are also close to perfection.

The other martial arts, which are slightly weaker, are also nearing perfection, such as the Heavenly Flame Spear, the Mountain Suppressing Fist, Blood Battle in All Directions, and the second level of the Thousand-Pound Breaking Formation. They have all progressed far into the Great Completion stage.

Most importantly, after completing the Yi Jin Jing and Xi Sui Jing to a minor degree, Chu Kuang's physical constitution improved to the sixth grade, and his cultivation speed increased by about 50%.

"With my current strength, if I were to encounter the Viper again, I could completely suppress him head-on."

Chu Kuang whispered, "As intermediate-level techniques, once mastered, these martial arts can be completely comparable to beginner-level techniques at the perfect level."

This greatly improved Chu Kuang's overall strength, allowing him to directly confront a level 9 martial artist.

"Among the first-year students at No. 3 High School, apart from Ye Qingfeng, there should be no one else who can rival me."

Chu Kuang spoke calmly, took out a halberd, stood up, and strolled out of the villa: "After more than a month of reflection, it's time for me to show my true colors in this final exam."
