Less than an hour after Zhang Xu left the Quidditch pitch, a series of flares rose in the sky like beacon beacons.

As previously agreed, a green flare was fired when Harry Potter was discovered, a red flare was fired if Harry Potter was in danger, and a yellow flare was fired if it was not found.

And now, in the sky, there is a green flare and two red flares.

Soon, Snape and Lupin brought the unconscious Harry and Zhang Xu back to Hogwarts and sent them to the school infirmary.

Harry Potter woke up the next morning after being traumatized and suffering from multiple frostbites.

And Zhang Xu, who found Harry Potter, was in a coma for three days before waking up.

When Zhang Xu woke up, he felt that his head was as messy as if he had just been put in the washing machine and dried, and his body was extremely tired, and it was very difficult to move his fingers.

Zhang Xu finally understood at this moment why Dumbledore didn't use the time turner to press Voldemort to the ground and rub it.

The issues involved in time travel are so profound that even the inventors and makers of time converters know only a few of them.

After using the time converter, Zhang Xu realized that it was not only the magic on the user's body that affected the use of the time converter, but also the soul of the user.

The first time he used the time converter, he didn't know any of this. He had turned the hour hand four times, and when he came back to his senses he was lying in a thatched hut with a black bear skin underneath him. At that time, his condition was the same as now, his head was a mess, and he didn't have any strength in his body.

After a full recovery of more than ten days, due to the language barrier, he used the Dementor Mind he had just mastered on the little girl who had been taking care of him all this time.

After learning that the little girl who rescued herself from the wild unconscious, their tribe was ready to go to war with the other two big tribes, and the boss of their tribe was called Chi You, Zhang Xu did not hesitate to take the little girl to jump back.

On the way to jump back, Zhang Xu used spells to make more than ten longbow belts, indicating that he was not here to find his ancestor to eat rice.

The Yellow Emperor, who got eighteen horizontal longbows of the Han Dynasty, was very happy, and asked his eldest son to recognize this white and tender young man as his godson on the spot, and gave the young man who called himself "Xu" the surname "Zhang", and then gave him eighteen sisters.

When his fifth brother, Zhang Hui, the ancestor of the surname Zhang, came to him to make a bow with him, Zhang Xu, whose feet were still a little soft, was still in a state of confusion.

In this way, Zhang Xu lived a life of making bows in the white sky and studying time turners and human structures in the late Neolithic period at night.

After participating in the Battle of Zhuolu, Zhang Xu finally figured out the reason why he ran back to the Neolithic Age.

A time turner is like a map of time, and the user sets a point on the map when he or she reaches that time.

And the user's magic is a scale on the time map. The greater the user's magic, the greater the scale.

A large scale means a low zero, assuming that Hermione is at the city map level when she uses the Time Converter, and Dumbledore is at the world map level when she uses it. If there is an error of one millimeter on two maps at the same time, the error on the map of the city is the same as the distance across the road, and on the map of the world, an error of one millimeter is enough for a person to fall into a ravine.

The time converter is also used with the influence of the soul, and the difference in the influence of the soul of people in this world is so small that it can almost be calculated as a constant. And Zhang Xu's soul comes from another world, so the impact is huge, not only time, but also space.

And time travel has an impact on the magic and soul of the traveler, and the greater the strength of the two, the greater the backlash caused, so Zhang Xu and Zhang Xu were tragic when they first used it.

After figuring out the situation, Zhang Xu adjusted the time converter and changed it to a mode suitable for his own use.

On a sunny day, Zhang Xu used transfiguration to conjure an open-air round platform according to the mound altar in the Temple of Heaven Park in the open space, and after bidding farewell to the ancestors, he activated the time turner on it, and left with a large number of photos and cultural relics.

When the second time travel arrived at his destination, Zhang Xu fell into the water with a puff.

The backlash that Zhang Xu encountered this time was not serious, but he was a little dizzy.

Soon, Zhang Xu was fished up by a gorgeous boat passing by, and the people sitting on the antique boat were all people with Shaanxi accents, all of whom were surrounding Zhang Xu to see the strangeness.

After recovering for a while, Zhang Xugang wanted to ask what era it was and where it was, when a storm suddenly rose on the water.

Just as the big ship was about to be overturned, the fat man on the boat, who looked like a leader, asked someone to throw Zhang Xu back into the water and pray for the gods to calm their anger.

So Zhang Xu, who had just come back to his senses, was thrown back into the water by a group of Kansai big men.

Zhang Xu, who entered the water for the second time, just floated his head, and his head was hit by a stone thrown from the boat.

The depressed Zhang Xu scooped up the stone that hit him and put it into the treasure bag, then opened the time turner and ran away.

In the third time travel, Zhang Xu was not counterattacked.

This time, Zhang Xu went to the top of a wooden building, and found that a man in a dragon robe was holding a box and setting fire to the building.

Meeting is fate, the old man surnamed Li who was determined to die refused Zhang Xu's suggestion to take him away, but handed over the box in his hand to Zhang Xu, and asked him to hand it over to the Ming Lord in the future.

Just as Zhang Xu completed his fourth time travel, the backlash came again, this time lying on all fours in what looked like a ship's cabin, and the sound of cannons and explosions on the ship came and went.

After Zhang Xu recovered, he put on a bunch of protective spells and opened stealth, and then ran to the bridge in chaos.

At this time, Zhang Xu knew where he was - on the afternoon of September 17, 1894, the Yellow Sea, the Zhiyuan.

At this time, the Zhiyuan had already begun to accelerate towards the Yoshino, and at the same time was under siege by the Japanese naval fleet.

In the face of the steel war machine, the strength of the individual is small, even Voldemort and Dumbledore, the shell of a naval cannon is only a lunch.

Zhang Xu immediately took out the life-saving hole cards at the bottom of the pressure box, and placed pieces of jade with powerful mana on the floor.

Regardless of whether he would be discovered by the people on the bridge, Zhang Xu mobilized his mana and cast a levitation spell on the Zhiyuan.

In an instant, the weight of more than 2,000 tons of the Zhiyuan was reduced by more than half, and the Zhiyuan, which had been slowed down due to injury, immediately flew out a lot, and the speed was much faster than when it was intact.

For a time, all the shells fired from the Japanese ships were left behind by the Zhiyuan.

The people on the bridge sensed something strange behind them and looked behind them.

Zhang Xu, who was maintaining the operation of the spell, felt everyone's gaze and shouted loudly: "Aiming at the Yoshino, there is only one chance!" ”

When Deng Shichang heard that it was a friendly army, he didn't bother to ask more, and turned around and continued to command.

Seeing that he was about to collide with the Yoshino, Zhang Xu adjusted the flow of mana and replaced the floating spell on the Zhiyuan with an ironclad spell concentrated on the bow of the ship.

Only a "boom" was heard, and the Zhiyuan crashed headlong into the starboard side of the Yoshino.
