Under Delhi\'s unfeeling description, Zhang Cheng gradually figured out the context of the matter, especially the origin and builder of the towering tower, which bothered him, and finally had a definite answer.

At the same time, he also realized that the world of the song of ice and fire was not as low magic as he initially imagined, but the place where the story happened was just in the environment where magic was relatively scarce.

In the more distant east, such as Yasha next to the shadow land, magic is definitely not a rare thing. On the contrary, magic can be seen everywhere, and there are many kinds of caster organizations.

If you can go there in person, it will be of great benefit to the construction of magic theory, which is still under exploration, or to absorb new knowledge and views.

However, unfortunately, he did not have enough time to complete such a dangerous long-distance trip. He had to suppress his impetuous curiosity, turn around and say to the terrified soul in a meaningful tone: "Dear Delhi, could you please tell me how to use this interesting little thing? Since you came all the way from Asia, you must know how to make it work, right?"

"No! I don\'t know!" Delhi trembled subconsciously and shook his head desperately.

"Oh? Are you sure? You know, lying is not a good thing, especially in front of me." Zhang Cheng gently stroked the sharp sword of the soul arrest messenger and threatened.

He would not believe that someone would risk his life to cross the whole known world and come to this dusty tower for thousands of years without knowing how to use the so-called "tears of the queen of the deep sea".

"Damn it! Don\'t push me! I can\'t say it! I really can\'t say it!" Delhi began to roar wildly.

Looking at the suffering eyes of the other party, Zhang Cheng suddenly smiled and comforted: "Relax, don\'t be so nervous. I didn\'t force you. I just wanted to put forward a suggestion that is good for both sides. Just tell me how to use it, and I\'ll release your soul. Don\'t worry, no third party will know about it except you and me. What\'s more, after solving the fool outside, I\'ll disappear for a long time behind you The organization will never know that you have revealed some secrets you shouldn\'t have revealed. "

"Really?" Delhi grew up incredulously.

As an unlucky guy who has lost all his cards and even his soul is held in the palm of others, he can\'t easily give up this life-saving straw, even if it may break at any time.

"Of course! You\'ve been with me for so long. When have you seen me break my promise? Not once! So you should believe me." Zhang Cheng nodded sincerely.

Even he didn\'t realize it. With half a year\'s experience in the world of ice and fire, his state of mind has unconsciously completed a change, from being cautious to being able to calmly analyze the opponent\'s psychology under any circumstances, and then react quickly to make the situation develop in a direction beneficial to himself.

In fact, he now grasped Delhi\'s eagerness to get rid of being controlled by others and wanted to get the use of "tears of the queen of the deep sea" from his mouth.

As for keeping his promise, he didn\'t think about it from the beginning.

Because in his subconscious mind, there is always a yardstick to measure the value of things. When the value of fulfilling the promise is lower than the psychological criterion, he will choose to generously fulfill the promise he has made, no matter whether it will cause damage to his own interests.

But when the value of fulfilling the promise is higher than the psychological criterion, he will not hesitate to show another side, that is, tear up the agreement, or even kill the guy who reached an agreement with himself.

Whether it is to abide by the promise or tear up the promise, it is not absolute for him. It can be changed anytime and anywhere. The current situation undoubtedly belongs to the latter

Delhi obviously didn\'t know that half of his foot had fallen into the abyss of death. He was still thinking about what Zhang Cheng had done during their time together.

As a result, he was surprised to find that the young people in front of him didn\'t seem to have broken any promises. At most, he added some verbal loopholes in the promises in advance.

After thinking this clearly, he immediately proposed: "give me a promise! Promise that as long as I say how to use it, you will release my soul immediately."

"I promise that as long as you tell me how to use it, I will release your soul immediately." Zhang Cheng repeated the other party\'s request without thinking.

The expression on his face was so sincere that no one would believe that the guy with this face would soon tear off his disguise and show his ferocious fangs.

"Good! Very good!" after getting the guarantee he wanted, Delhi breathed a sigh of relief and began to explain in a somewhat vague tone: "As you can see, the tears of the queen of the deep sea is a magical substance composed of pure energy. We don\'t know how it is formed, but one thing is certain that only women can resonate with it."

"You mean... I\'ll never use it unless I change my gender?" Zhang Cheng raised his eyebrows in surprise.

Gender restrictions!

Is there anything more incredible in the world?

According to Dalaran\'s basic theory, the mutual exclusion of all magic energy is mostly due to the opposition of the two energy properties, such as holy light and shadow, nature and evil energy, etc., while the arcane skill used by mages is a relatively neutral energy, which can not only simulate elemental energy such as frost and flame, but also simulate shadow, nature Death and other forms of energy.

He doesn\'t understand why such a wonderful situation of gender restriction occurs in an energy material with water element energy as the main body, which is completely unreasonable.

"Yes! According to the records in the organization and my personal research, it really only resonates with women, and the purer the age and heart, the better. In addition, I suggest you\'d better find a master for it quickly, otherwise it will have an uncertain impact on you if you wear it for too long. That\'s all I know. You can fulfill your promise and release it now "My soul," he said, and Delhi\'s soul floated slowly, indicating that he wanted to leave immediately.

There was a strange light in Zhang Cheng\'s eyes. At the same time, the corners of his mouth tilted slightly. He replied with a smile: "sorry, I\'m afraid I\'m going to break my promise. Eat him and arrest the soul messenger!"

"I\'ve been waiting for your orders for a long time! You don\'t know how delicious his soul is. It\'s like a delicious meal in front of him. It\'s an unbearable temptation."

The licensed magic sword was very rare. He joked and then released a black fog to wrap Delhi.

Although he struggled, yelled and cursed desperately, he was finally pulled into the sword bit by bit, leaving only a relief of pain and despair at the end of the hilt
