The book "The Origin of Witchcraft" given by the wizard Seg is not like the skill books or scrolls obtained before. You only need to recite it silently to use or study it. The knowledge in the book will turn into a stream of information and be imprinted in your mind.

This book, The Origin of Witchcraft, was just like the apprentice textbook that Sage had given him before. Xu Feng needed to spend a lot of time to learn, understand, and master it word by word...

As the days passed, tens of thousands of apostles from the secret realm came to climb the tower on Tongtian Island every day. This was much safer than exploring the secret realm. As long as they climbed to one level of the tower, they would receive corresponding rewards. Even if they were defeated, they would not really die. Death in the Tower of Babel would only affect their spirits at most, and they would recover after resting for three to five days. However, the rewards obtained from the Tower of Babel were real.

Now in Tongtian Island, there are more than 300 chambers of commerce like the Dawn Chamber of Commerce that buy and sell goods. Business is booming every day. The entire Tongtian Tower is like a real world.

As time went by, Xu Feng spent most of his time studying "The Origin of Witchcraft". Occasionally, he would enter the Tower of Babel to defeat domain-level masters and complete the task of upgrading his golden body.

A few months later, Xu Feng finally mastered "The Origin of Witchcraft".

A new skill tree also appears in the interface of the second profession. The name of this new skill tree is called the Origin of Witchcraft.

The moment the witchcraft origin skill tree appeared, Xu Feng's second career also changed from a wizard apprentice to a first-level wizard.

When Xu Feng became a real wizard, Seg left Tongtian Island, broke through the void, returned to his own wizard tower, and continued to wander and explore various world planes.

…

"Witchcraft, flame plasticity!"

Xu Feng's mind moved, and a ball of fire appeared in his palm, burning fiercely.

Under the guidance of Xu Feng's thoughts, the flames kept changing their forms. Sometimes they transformed into a gracefully flying bird, dancing gracefully; sometimes they transformed into a majestic fire dragon, roaring and releasing fiery energy. They were lifelike, as if they were part of Xu Feng's body, changing flexibly with his thoughts, as nimble and unpredictable as the fingertips on his arms.

Ding-ling-ling~ The phone rang, and Xu Feng was distracted for a moment. The flame in his hand that had just transformed into a bird exploded with a "bang", and sparks flew everywhere.

Xu Feng frowned slightly, shook his numb right hand, and took out his phone.

"Xu Feng, your father is seriously injured..." A familiar voice came from the phone.

Crack~ Xu Feng's expression froze, and the phone suddenly broke into pieces. The next moment, a pair of black wings appeared behind Xu Feng, and his figure soared into the sky like a flash of lightning.

…

It took Xu Feng only a dozen minutes to travel hundreds of kilometers to reach the Yanjing City Defense Office;

Upon noticing Xu Feng's arrival, a group of secret realm apostles immediately rushed out of the City Defense Office's office building. Each of them had a vigilant look on their face, as if they were ready to fight at any time.

"Xiao Feng!" Zuo Zhidao, deputy director general of the City Defense Bureau, showed a look of surprise on his face.

Xu Feng's whereabouts were no secret to the City Defense Office. Ever since Xu Feng's name was ranked first on the Heavenly Ranking, the City Defense Office paid much more attention to him than before. The previous phone call was made by Zuo Zhidao himself to Xu Feng.

Tongtian Island is more than 600 kilometers away from Yanjing. Even if you take the nearest flight, it will take several hours. Unexpectedly, only more than ten minutes later, Xu Feng flew back to Yanjing from Tongtian Island.

"First aid is being given..." Zuo Zhidao also knew the seriousness of the situation. Without further ado, he took Xu Feng to the City Defense Office's own hospital at its headquarters.

Xu Feng stood in front of the bed, looking at Xu Nantian, who was extremely skinny, as if all the blood in his body had been sucked out and whose breath was extremely weak. A hint of anger suddenly appeared on his face.

"No recovery potions, pills or skills can cure Nantian's condition. Now he can only maintain it with difficulty..." Zuo Zhidao stood next to Xu Feng and felt like he was standing on the crater of a volcano that could erupt at any time.

Xu Feng's mind moved, and a healing talisman with gold characters on a black background appeared in front of everyone. As the healing talisman slowly merged into Xu Nantian's body, Xu Nantian's originally pale cheeks slowly showed a hint of redness, and his breath became more stable.

Xu Feng couldn't help but frown when he looked at his father's condition at this moment. His healing talisman could only temporarily stabilize Xu Nantian's condition and prevent it from getting worse. He still had a long way to go before he could fully recover.

Xu Feng took a deep breath, stretched out a finger and pointed it at Xu Nantian's forehead. A trace of magic power condensed at Xu Feng's fingertips. The moment his fingertips touched Xu Nantian's forehead, a faint light like a spider web emerged from Xu Nantian's forehead.

Detecting the source of the disease!

This is a first-level witchcraft that only formal wizards can master. It can detect the causes of some diseases that cannot be detected by ordinary methods.

Soon, Xu Feng saw that there were countless tiny bloodworms like dust in Xu Nantian's internal organs and blood vessel walls. They were constantly devouring the blood and nutrients in Xu Nantian's body, inhibiting Xu Nantian's recovery.

Xu Feng took a deep breath and asked in a low voice: "What on earth happened? Why did my father become like this!"

There is no wrong version in the 1619 book forum!

…

Xu Nantian has always been a reserved person, rarely showing his deep love for Xu Feng. When Xu Feng's mother passed away, the father and son always depended on each other.

In Xu Feng's heart, Xu Nantian has always been an admirable figure, who seems to be able to hold up the entire sky, firm and upright. As the director of Songtao City Defense Bureau, no matter how hard or busy the work is, he never complains and silently bears everything.

However, Xu Nantian, who was lying on the hospital bed at the moment, was hunched over and as thin as a withered bone. He was only forty years old, but he looked like a candle extinguished by the wind, and looked old and frail.

"It was the blood clan, a blood clan grand duke took action!" Zuo Zhidao whispered, "None of us thought that he would dare to violate international treaties and sneak in secretly. He was like a killer, one strike and then leave. We didn't keep him!"

"Grand Duke of the Vampire Clan!" Xu Feng frowned slightly. When he heard the word "vampire", the first person he thought of was Baron Hawke, who had a grudge against him.

Xu Feng not only killed Baron Hawke, but also killed his only offspring. The entire Hawke family might have to be removed from the blood clan. How could a small blood clan baron family possibly alarm a blood clan grand duke? Moreover, this incident has been several years in the past. Even if they really wanted to avenge Baron Hawke, how could they delay it until now? "What's the name of that blood clan grand duke? I need all his information!" Xu Feng said coldly.

"The blood clan grand duke is called Mendir. We are collecting information about him and his family. In ten minutes, all the information will be handed over to you!" Zuo Zhidao said seriously.

"Grand Duke Mendel of the Blood Clan..." In Xu Feng's pupils, black calamity power flashed continuously like lightning, and surging murderous intent continued to spread from his body, and a layer of light black ice slowly floated over the entire room.
