At the same time, Tianjin.

For Zhang Yicheng, tutoring is nothing more than a sentence; As for Zhou Yunyan, giving Zhang Yicheng tutoring is nothing more than a bigger punishment. Zhou Yunran's tutoring ideas are nothing more than traditional tutoring methods such as "if you don't have any questions, just ask me, I'll tell you" and so on, and Zhang Yicheng opened the outline of the exercises and was stunned for a long time, but he didn't ask a single question.

"Do you know how to do these questions?" Seeing Zhang Yicheng frowning and not speaking, Zhou Yunran was also stunned, could it be that he would know all these questions? Is it pretended to study badly?

"I won't ......," Zhang Yicheng shook his head.

"Why don't you ask me......" Zhou Yunran was quite stern.

"I don't know where I won't ......" Zhang Yicheng's eyes were extremely innocent.

"You did it on purpose, right? Will it be then? ”

"It's not that I can't ask the question, it's that I don't know how to ask...... You tell me how to pronounce this symbol first......" Zhang Yicheng pointed to the "∑1" in an algebra problem.

"Oh my God......" Zhou Yunran slapped her head with a look of despair, "How did you graduate from junior high school?" ”

"Could it be that this thing has been around since junior high school?" Zhang Yicheng flipped the textbook over and over again to change the angle, "It's not like ah, I don't seem to have seen such a thing in junior high school......"

"Faint to death......" Zhou Yunran was also helpless, "Forget it, let's make up chemistry first today......"

"Okay, chemistry is my forte......"

"You start with the first chapter of the comprehensive exercise syllabus, and ask me if you have any questions......" Zhou Yunran said tremblingly, "I don't know how to ask this, right?" ”

"No, no, this will definitely ask......" Zhang Yicheng was quite confident, "Come on." You see this problem: Fe, Cu, Fe2+, Fe3+ and Cu2+ are fully reacted in the same container, if Fe is left, then there can only be ...... in the container Alas, do you think these grandchildren are full of food? What if you mix so many things together and blow them up? Also what 'if there is a surplus of iron'. How did he know that there was a surplus of iron? ”

"This ...... Is that your problem? "Zhou Yunran is dying.

"No, no, no, I just think these questions are too mentally retarded...... Zhang Yicheng smiled, "Look at you, there is also this question" According to media reports: There have been lawbreakers in the society who used brass (copper, zinc alloy) to counterfeit gold to carry out fraudulent activities. Please design an experiment to identify brass and gold'. Look at the answer later: put brass and gold into dilute nitric acid respectively, dissolve brass, and non-reactive is gold, don't you say this is looking for pumping? In order to prevent fraud, I also have to carry a bottle of nitric acid with me, and if I really have a bottle of nitric acid, I will identify a fart. Is it okay to splash directly on the face? ”

"Hahaha......" Zhou Yunran smiled happily, "Can you be serious......"

Before I knew it, it was late at night, and instead of improving, Zhang Yicheng's level was pulled down, but Zhou Yunran's level was pulled down......

Saying goodbye to Zhou Yunran and returning home in a hurry, the first thing Zhang Yicheng did was to turn on the computer to play games, and it was delayed for several days, but he didn't even have a boss, is this okay?

However. Just when he first entered the game screen, a burst of low blood sugar dizziness made Zhang Yicheng almost hit his head on the screen, and then these two eyes were like rubbing sand. The upper and lower eyelids fought vigorously, at first, this Zhang Yicheng thought that he had used his brain too much to tutor with Zhou Yunran just now, and he deliberately went outside to wash his face with cold water, but he didn't expect that he couldn't stay up again as soon as he returned to the house, so he had no choice but to turn off the computer and sleep. As for why he was suddenly so sleepy, Zhang Yicheng himself wondered. For three years, I gave up the game because of physical exhaustion. This is the first time, is it really the excessive use of the brain that causes premature aging?

……

"Zhang Yicheng, where's your father?" In the haze, Zhang Yicheng seemed to hear someone talking in his ear, the voice was very familiar, but he couldn't remember who it was for a while.

"My dad?" Zhang Yicheng opened his eyes in a daze, only to feel that he couldn't see his five fingers, and he touched it outside, feeling that there seemed to be a stone wall around him, damp, and he didn't know where it was.

"Zhang Yicheng, where's your father?" At this moment, Zhang Yicheng heard the voice just now again.

"yes, where's my dad?" After hearing this voice, Zhang Yicheng also began to wonder inexplicably, in his memory, the last contact with Zhang Guozhong seemed to be a long time ago, if it weren't for this voice reminder, he would have almost forgotten that he still had a father.

"Am I dreaming?" Standing up, Zhang Yicheng touched his body, there was a real touch, it seemed that he was wearing a dress that he had never worn before, and he was carrying a large canvas bag for his magic device behind his back.

"Dad!" Holding the stone wall beside him, Zhang Yicheng walked forward and shouted with one foot deep, shouting and shouting, only to feel that the stone walls on both sides suddenly disappeared, and the space outside suddenly became clear, and there was a waterway seven or eight meters away from him, leading directly to a cave not far away, and there seemed to be a person lying next to the waterway.

"Dad... Is that you!? Zhang Yicheng wanted to go over to look for it, but he felt that his legs were like being filled with lead, and he wanted to move forward but couldn't take a step anyway.

"Find your dad!" The sound in my ears seems to be getting farther and farther away......

"Dad!!" Suddenly, Zhang Yicheng sat up, only to see that the sky outside the window was bright, it was definitely a rare good weather, and he looked up at the wall clock on the wall, it was almost nine o'clock, and it seemed to be a dream just now.

"Damn, it's really a dream......" Just when Zhang Yicheng was napping, he suddenly heard a strange voice in his ears that seemed to be in a dream, "Go find your father!" ”

"I'll rely on ......" Zhang Yicheng's head buzzed, and he immediately woke up, isn't this voice the voice of the "immortal" who led him to subdue Zhou Sen and rescue Zhou Yunran not long ago? "Go find your father...... What do you mean? In confusion, Zhang Yicheng picked up his mobile phone and dialed Zhang Guozhong's number, prompting that the phone had been turned off, and then dialed Lao Liu Tou's mobile phone, but it was still turned off.

"This group of old and unscrupulous people, why don't they turn on any of them......" After hesitating, Zhang Yicheng directly dialed the phone to the Baqianli Road Inn, and only after inquiring did he know that the three of them had set off into the mountain early in the morning.

"Mom!!" hung up the phone, Zhang Yicheng was full of energy.

"What's the matter?" Li Erya, who was drying clothes in the courtyard, seemed to hear Zhang Yicheng's voice, and trotted into the house.

"I need to go to my dad!" Zhang Yicheng turned over and got out of bed, "Hurry up and get me some money!" ”

"What are you looking for him? What demon moth do you think of again? Li Erya crossed her hands and frowned.

"It's not a demon moth...... It's God's will......" Zhang Yicheng said casually, "Today the gods gave me a dream, let me go to my father!" ”

"The will of the gods?" Li Erya almost died of anger, "I think you're quite godly!" Your dad said, let me stare at you and study! Don't go anywhere but school! The exam is still ten days away, so you can't stop and stop? ”

"Mom, you know about the bad guys I caught two days ago, right?" Zhang Yicheng looked indifferent, and didn't pay attention to the stubble of the exam at all, "The outer ring road, such a corner community, do you know how I found it?" Zhang Yicheng squinted and said, "Didn't my dad tell you that I have an immortal attached to me?" ”

"Huh?" Li Erya was also stunned, as if she had heard the old man say that her son had a big immortal two days ago, and it seemed to be quite powerful, because his father had been tossed by gods and ghosts for many years, and when it came to gods, ghosts and ghosts, Li Erya even believed more than Zhang Guozhong, "He seems to have really mentioned a mouthful......"

"You see that's right...... Zhang Yicheng said calmly, "At the beginning, it was the immortal on my body who guided me to find the place, and now the immortal is pointing me to find my father!" Do you think I'm going to go? ”

"Huh?" Hearing Zhang Yicheng say this, Li Erya immediately panicked, "Then your father won't be in any danger, right?" ”

"Don't think about it!" Zhang Yicheng pursed his lips, "The gods just said to let me find it, but I didn't say anything else!" Who knows what's going on? Maybe it's picking up a lottery ticket in your wallet? The gods asked us to do this, let's just do it, don't ask anything else, it's all a heavenly opportunity, and you can't disclose ......! ”

"Then you ...... exam" Li Erya was still not at ease.

"What test? In case you buy a lottery ticket halfway and win 1.8 million, which one else will you try......" Zhang Yicheng seemed a little impatient, "Okay, okay, you get me some money, I'll go to my dad ......" While saying, Zhang Yicheng dialed Zhou Yunran's phone, he just dropped out of school after making up a class, and he had to say hello to the girl anyway, right?
