At Beiyan Checkpoint in the Qin Kingdom.

The magnificent Great Wall was as dormant as a huge dragon. From a closer look, the Great Wall looked even majestic and new. Obviously, it had just been built.

The sand filled the land, and the scorching sun made every civilian sweat.

The armored soldiers were on patrol.

"D*mn it, I'm just a weak martial artist. Otherwise, I'll definitely kill you all!" A man said. 

Looking at the skinny civilians who died from exhaustion under the Great Wall, Ye Hua clenched the long spears in his hands.

He had time-traveled three years back and became a soldier guarding the Great Wall. Even though he knew all the advanced technology, he could do nothing at the moment.

Just the day before, a small team of the Xiong people attacked the Great Wall at night and killed hundreds of civilians. By the time the army guards of the Great Wall realized what was going on, they had already left. The army guards could do nothing about it.

Ye Hua was standing on the Great Wall with the blazing sun above his head. Looking at the yellow sand in front of him, he couldn't help sighing in a low voice.

"The most terrible thing is that there are martial arts in this world, but I'm already 18 years old, and my bones have been fully developed..." Ye Hua mumbled. 

"Ding, the host has successfully activated the new daily sign-in system. Do you want to start binding hit?" The system said. 

"System? Binding?" Ye Hua was curious. 

His eyes narrowed and his face showed excitement.

In his previous life, he was a person who liked reading novels and stayed at home for most days. How could he not know what it was?

After waiting for so long, it finally appeared!

"Let's bind it!"

Ye Hua murmured in his heart.

"The binding of the system is successful. The host will be given a reward if signing-in at any place," the system announced. 

"A gentle reminder, the more special the location of signing-in is, the more generous the reward will be," the system notified. 

"Is this a sign-in system? It's similar to the game I played in my previous life," Ye Hua thought. 

He suppressed the excitement in his heart and said, "I want to sign-in at the Great Wall!"

"Sign-in location, Great Wall. If you succeed, you will be rewarded with an Inborn Body of Martial Artist!" The system said. 

"Inborn Body of Martial Artist?" Ye Hua was even more curious now.

"The Inborn Body of Martial Artist will greatly speed up the process of the host's practice of martial arts and make you a once-in-a-hundred-year martial art genius in the world," the system said.

"In this way, I can protect myself in this fortress!" Ye Hua thought. 

Ye Hua stood where he was and began to regulate his breathing.

.......

The martial art breathing method he used was the most popular one in the army, and it was also the most suitable breathing method for most people.

He didn't know much about the realm of martial arts in this world.

He guessed that there were roughly divided into innate and acquired.

Then, it was further divided from level 1 to level 9. 

The division of each level was extremely strict. In the Qin army, an acquired level 3 man could easily tear up tigers facing hundreds of enemy alone. 

"I'm just a mortal now. I'm not even a level 1 public officer. Although I've got the system, the battlefield changes rapidly. I'd better keep my strength and take things slow," Ye Hua thought in his heart. 

His thoughts turned into a burst of perseverance.

With the use of the breathing method, streams of faint genuine Qi began to gather in his body.

Not long after, the stream of genuine Qi of the size of an egg took shape inside his body.

Ye Hua opened his eyes, and his eyes were shining. 

He had entered the first realm of martial arts, and acquired level 1.

Martial arts were not as difficult as he had imagined!

Of course, Ye Hua knew very well that this was the effect of the system reward of the Inborn Body of Martial Artist. Otherwise, he would not have entered level 1 in a short period of time.

"Ye Hua, the food is coming right away," a soldier yelled. 

The soldier who was standing guard beside him came over and looking at Ye Hua in surprise.

"Have you broken through?" The soldier asked. 

This burly man was Ye Hua's corporal, Zhang Kui.

As he was a few years older than Ye Hua and the others, he took good care of his brothers.

"Mr. Zhang Kui, when I was standing guard, I practiced my breathing method, but I didn't expect that I would suddenly break through it," Ye Hua said. 

He smiled shyly.

Zhang Kui laughed with great excitement. He gave a heavy pat on Ye Hua's shoulder.

"That's good! From today on, you have a chance to kill the enemy and make achievements. You will become a corporal and become a public officer in no time!" Zhang Kui said.

Public officer is the rank 1 title among the 20 ranks in the Qin Kingdom.

Although it was only rank 1, the soldier would be given a house, a hundred acres of fertile land, and someone to help you to manage the fields.

It could be said that a rank 1 soldier was no longer a commoner and no longer lived in vain.

When the clock struck midnight, after the team of soldiers handed over their task to another, Ye Hua and his companions' duties for the day were completed.

In the small military tent, a group of people were eating around the fire.

Zhang Kui suddenly stood up and said to the other four, "Today is a good day. I have an important news to announce."

"Mr. Zhang Kui, what's the matter?" A soldier asked.

It was Li San who asked, the new recruit who had just joined the team.

"Would it be that we are having an extra meal for tomorrow? Would there be mutton?" Li San said hopingly.

"No," Zhang Kui said. 

Then, he looked at Ye Hua with a smile.

"Today, one of us brothers has broken through to the level 1 of martial arts. Congratulations!" Zhang Kui said.

"It's a pity that we can't drink in the military camp. Otherwise, we would have had a good time drinking with Ye Hua!" Zhang Kui said.

In Ye Hua's group, except for Zhang Kui and himself, the other four soldiers were added as new recruits.

In this way, Ye Hua had a deeper brotherhood relationship with Zhang Kui. It was not an exaggeration to say that they were blood brothers on the battlefield. They could trust each other with their lives. 

When the other four recruits heard that Ye Hua had become a martial artist, they all looked envious.
