Looking at the pure and impurity free eyes of the son of the forest, Zhang Cheng couldn't help laughing and shaking his head: "Sorry, little guy, I'm afraid I can't agree to your request. Because you are so precious. Whether it's the knowledge in your mind or the magical ability you master, it's of great research value to me. In short, from now on, you are my prisoner and the object of research and learning."

"Greed, desire, ambition... Human beings, I feel the naked malice from you. No matter what you want from me, I promise you won't get it." withered wood raised his head and responded in a non emotional tone.

Obviously, he did not understand the true meaning of the so-called "learning" and "research".

"Ha ha! Don't be so sure. Please believe me, you have no right to refuse in this matter. Well, that's all for today's conversation. Now you need to have a good sleep in order to cope with the next experiment full of pain and despair." After saying that, Zhang Cheng took out a bottle of potion glittering with purplish red light from his pocket, forcibly squeezed the other party's mouth and poured it in.

Although the son of the forest tried his best to resist, with the liquid flowing down his throat into the digestive system, he fell into a trance in just a minute or two. Finally, he completely closed his eyes and fell to the ground with a plop, making a slight snore.

Geoffrey kicked the little man in the head and asked with interest, "what did you give him to drink?"

"Nothing. It's an insignificant hypnotic. Anyone can completely forget his troubles and enter the sweetest dream as long as he drinks a little. Moreover, in the dream, the user will quickly recover his strength and energy. When he wakes up again, he will even have a feeling of rebirth." Zhang Cheng explained while releasing the dead wood from the iron shackles.

Because he could clearly perceive that, for some unknown reason, iron products were constantly weakening the magic ability and vitality of the son of the forest.

No wonder the ancestors were able to fight the son of the forest with simple weapons and armor. It turned out that the son of the forest had a fatal weakness, that is, the fear of iron products.

If you are only bound by iron shackles, you will lose your ability. What if you are pierced by a sharp sword?

The answer is obvious. The chances of survival are slim.

In addition, the reproduction of the sons of the forest is not like human beings. As long as there is no large-scale war and plague, the number will double.

In essence, compared with animals, they are closer to intelligent life evolved from plants such as tree man. Therefore, neither fertility nor growth rate can be comparable with human beings. Finally, they gradually become the loser in this cruel competition and are forced to withdraw from the stage of history.

Sometimes it is difficult for Zhang Cheng to understand why nature creates a race so close to harmony and perfection, but it gives them a fatal weakness. On the contrary, seemingly mediocre humans can often use all kinds of harsh environments at a very fast speed. Even if there is a devastating disaster outside, they can survive and rebuild civilization with the survival ability of a "small strong".

Just when he felt a little sorry that the son of the forest was going to perish, Geoffrey, who could not bear the loneliness, stroked his beloved ring and couldn't wait to urge: "Mason, it's yours. You can take it back and study it slowly later. Now it's time to tell me what I should do next to make the flame released by myself more powerful?"

"Don't worry, your majesty, you should understand that the most important thing to learn magic is to be patient. Between your understanding of flame magic, I think the next thing to do is not to blindly improve the power, but to find out the source of your own strength." Zhang Cheng stood up calmly and replied with a smile.

He knew very well in his heart that the more magic knowledge he taught, the closer the king was to death.

The reason is very simple. The reason why the tiller family proposed marriage is to influence and even control the young king through their best means, so as to expand their power and influence.

According to the original plot, olena redwin just learned that Geoffrey was grumpy and cruel, so she decided to poison her marriage partner.

At present, Geoffrey is not only grumpy and cruel, but also has mastered the powerful flame magic. It's a great threat to the queen of thorns. She won't be willing to waste her hard trained Marguerite on such a guy.

However, Zhang Cheng does not intend to interfere in the secret actions of the tiller family. He just intends to use Geoffrey to tell everyone that he has enough knowledge and ability to make an ordinary person extraordinary, and has enough power to change someone's fate.

When the fragile balance is broken, everything he shows will become rich political capital and the object of all parties.

"The source of power?" Geoffrey obviously didn't know that half of his foot had stepped into the coffin, frowned and began to think hard.

"Yes! The source of power. Think about it, why did dragons and magic flourish for a period of time and then slowly disappear until they suddenly sprung up in recent months? Is it just a coincidence?" Zhang Cheng didn't give a direct answer, but put forward a series of rhetorical questions.

"You mean... There's a magical force behind all these incredible things?" Geoffrey seemed to realize something, and his eyes glowed with excitement.

Zhang Cheng nodded slightly: "yes! Do you remember the red comet in the sky not long ago?

According to my research and observation, all the magic in the whole world and the mysterious energy on which dragons live all come from this.

In other words, when a comet passes through the world we live in, it will bring a lot of abundant magic energy, so when it appears, it will lead to the prosperity of magic and dragons.

But with the passage of time, there is less and less energy in the air, and magic will slowly fade out of people's sight and become a story that only exists in legends.

Many people think that the appearance of the dragon is a sign of the revival of magic, but in fact, the red comet is the root of all magic power.

Your majesty, you are lucky to be in time to learn magic.

Please close your eyes, feel the energy in the air with your heart, try to absorb and control them, and then you will understand what the source of your strength is.

When you understand the essence of magic, you will naturally know how to improve the power of fire spell... "
