Great Qin Chang’an Jun

The war was temporarily in a stalemate, part of the Qin army was stationed in Tunliu City, and some was outside the city, fighting each other, and the Zhao army’s individual combat ability was not comparable to the Qin army, and the number was not superior, and it was inappropriate to take the initiative to attack the Qin army.

In the city, Cheng spent most of his time on calculations.

I saw that in front of Cheng Yu were wooden boards, bamboo simples, as well as parchment rolls, paper, cloth silk, etc.

In this world of Qin Shi Ming Yue, there is paper, but it is very rare, so it is expensive, and ordinary people simply cannot afford to use it, not only paper, but even corn, stockings, etc.

Today, Cheng is fiddling with a humble calculation.

Without a computer, Cheng Yu can only make his own abacus, calipers, compasses and other tools.

I’ve been working hard for three days in a row.

“Whew, it finally worked.” Cheng Yu took a long breath, and the whole person was extremely relaxed.

Using the mathematical knowledge he learned in his previous life, it took Cheng Yu three days to finally crack the mechanism of Oniyako’s copper box.

~

On the small stone arch bridge, Oniyako still sits with her eyes closed, holding a rusty bronze box in her hands.

As soon as Cheng Yu came, Oniyako opened his eyes.

“Senior, I have cracked the mechanism of this copper box.” Cheng Yu said.

Upon hearing that Cheng Yu had cracked the mechanism of this copper box, Ghost Guzi was a little suspicious, but he was looking forward to it even more, opening this copper box was the pursuit of the Ghost Valley Sect for generations.

“If I can open this copper box in my lifetime, I will die without regrets.” Oniyako thought to herself.

While thinking, Oniyako handed the copper box in his hand to Cheng Yu.

Taking the copper box, Cheng Yu fiddled with it for a while, a soft ‘click’, the mechanism operated, and the copper box slowly opened.

Seeing that Cheng Yu really opened the copper box, Ghost Guzi’s old face was also excited.

As the copper box was fully opened, Cheng Yu and Oniyako’s eyes looked inside the box together.

Inside this copper box is a turtle shell.

The ancient turtle shell has dense writing on it, which is the Qiwen script.

Cheng Yu couldn’t read the text, but Oniyako could understand it.

“Senior, the words on this tortoise shell are~” Cheng Yu looked at Oniyako.

Oniyako took out the turtle shell, looked at the texts on it, and thought seriously.

After a while, Ghost Guzi sighed: “It is worthy of being the first technique of the royal family of the Shang Dynasty, it is indeed mysterious, but unfortunately, the old man can’t cultivate.” ”

Seeing that Cheng Yu was still looking at himself, Ghost Guzi said: “The technique recorded on this tortoise shell is called purple electric thunder, which is an extremely profound mental method, but this mental method is extremely domineering, and the thunder and lightning true qi cultivated is extremely violent, and the damage to the body is great, so to cultivate this mental method, you must first have an extraordinary physique.” ”

“Purple Electric Thunder?” Cheng Yu’s heart was ecstatic.

Cheng Yu has the innate true qi of the thunder and lightning attribute, and he lacks an internal strength heart method of the thunder and lightning attribute, this purple electric thunder is very suitable, as for Ghost Guzi said to have an extraordinary physique, Cheng Yu is not worried, firstly, his body has a metamorphosis when it is split by heavenly thunder, and secondly, he already has the innate true qi of the thunder and lightning attribute.

Cheng Yu could be sure that he could definitely cultivate this purple electric thunder.

“How? You want to cultivate this purple electric thunder? Oniyako frowned.

“Yes.” Cheng Yu nodded.

“To cultivate this mental method, you must first abolish your own strength, and you must also endure great pain, and if you do not have an extraordinary physique, you are looking for death.” Oniyako said in a deep voice.

“Do you want to abolish the power?” Cheng Yu was stupid.

“Of course, if you are a thunder and lightning attribute true qi, you don’t need to abolish it, but you still need an extraordinary physique.”

The constitution is also divided into acquired, innate, transcendent, and sanctified.

The innate physique can be invincible, like Qin Shi Mingyue in the ceremony, Mei Sanniang and the like, they are all congenital physiques.

Hard work, that is, innate physique, a copper skin and iron bone, if you have an extraordinary physique, it can almost be said that you are not bad to see God.

“I want to give it a try, and I hope that my seniors will be successful.” Cheng Yu’s right hand was unfolded, and the palm of his hand emitted a faint electric light.

“The innate true qi of the thunder attribute?” Looking at the electric light emitted by Cheng Yu’s right palm, Oniyako exclaimed.

Those who have the innate true qi of the thunder and lightning attribute, except for Cheng Yu, Ghost Guzi has never seen the second person, nor has he heard of the second person.

“I can’t imagine that you will have the innate true qi of the thunder and lightning attribute, so, you can try to cultivate this purple electric thunder.” Oniyako said.

Cheng Yu opened this copper box for Oniyako, completing the pursuit of the Oniya faction for generations, and Oniyako decided to fulfill him.

At that moment, Oniyako first translated the text on the tortoise shell.

~

In a small courtyard, no one disturbed, and Cheng Yu could also cultivate with confidence.

I saw that Cheng Yu was sitting cross-kneeled on the ground, closing his eyes and concentrating, his thoughts were concentrated, his mind was too empty, and he hugged Yuan Shouyi.

Oniyako stood behind Cheng Yu.

At this moment, Cheng Yu had begun to carefully cultivate the purple electric thunder.

The innate true qi of the thunder attribute came out of Cheng Yu’s sea of qi and traveled through his meridians.

With the special meridians, combined with the special breathing, coupled with spiritual meditation, the innate true qi in Cheng Yu’s body also underwent subtle changes, and at the same time, he felt a tearing pain all over his body.

At this time, Ghost Guzi emitted a thick vertical and horizontal qi, which enveloped Cheng Yu.

With the help of Oniyako’s vertical and horizontal qi, Cheng Yu’s pain was alleviated at once.

With the conditions of Cheng Yu, cultivating purple electric thunder is still relatively reluctant, but fortunately there is Ghost Guzi to help.

“A good Chang’an Jun of the Qin State has become a tou, won Fan Yuji, defeated Li Mu, has courage and insight, uses troops wisely, and transcends the boundary between life and death, and can also crack the organ copper box that my Ghost Valley Sect cannot crack for generations, and now, with my help, he can cultivate martial arts such as purple electric thunder, he is really a genius of heaven, but unfortunately he didn’t meet it earlier, otherwise, he will definitely be included in the disciple, if there is such an apprentice, there is no regret in death.” Oniyako thought to himself.

At this time, a faint purple electric light came out from the palms of Cheng Yu’s hands.

The purple light gradually shines, the electric light gradually flourishes, and there is a faint tendency to condense into thunder and lightning.

It was nearly half an hour before Cheng Yu stopped cultivating.

When Cheng Yu opened his eyes, a purple essence light flowed in his eyes.

“Purple Electric Thunder has been successfully cultivated, although the innate true qi in my body is still a thunder and lightning attribute, it is different, more refined, and more powerful.” Cheng Yu thought to himself.

Without the help of Ghost Guzi, it would be difficult for Cheng Yu to cultivate into Purple Electric Thunder, so he quickly thanked Ghost Guzi.

“The situation in the Qin Kingdom will definitely change because of Cheng Yu, and the general trend of the world will also change because of him.” Oniyako secretly said.

Most people are changed by the situation, and only a very few can change the situation.
