It turned out that the monster was vulnerable to the giant ships and cannons.

Under the bombardment of the space battleships, the monsters that were showing off their might in the city were instantly wiped out and turned into a pile of useless garbage in the sea of ​​fire.

"Is this... all over?"

Looking at the scene in front of him, Takarada Rika spoke blankly, while Fang Zheng shook his head.

"No, not quite."

As soon as he finished speaking, he flashed and disappeared in front of the two girls.

The land swept by the beam was now charred black, with the broken arms and limbs of the monsters scattered all over the ground. Then, among the charred debris, a figure staggered out - it was none other than the black-clad weirdo from before.

However, at this moment, the strange man in black no longer had his original calmness and majesty. The robe he was wearing was blown to pieces, and only the flame behind his head was still burning.

"What is that?"

The strange man in black raised his head and looked at the metal warship floating in the sky, with a bit of doubt in his eyes.

"Forget it, no matter what it is, at least it seems that my mission has failed, but it doesn't matter, there is another world..."

“Puff.”

However, before the black-clothed weirdo could finish his words, the pitch-black giant sword swung down and split him in half. However, the black-clothed weirdo who was split in half did not fall down. Instead, he flashed and returned to his original state not far away.

"It's you..."

The strange man in black raised his head and stared at Fang Zheng who was holding Frostmourne in his hand.

"It seems that you are also one of the guests from outside. This is really beyond my expectation... Well, I lose this time. I will leave this world..."

"No, you're not going anywhere."

Fang Zheng swung his sword, interrupting the black-clad weirdo's words.

"You want to run away after you've messed up everything here? There's no such thing as a good thing."

"Do you still want to destroy me?"

Hearing Fang Zheng's words, the strange man in black smiled coldly.

"What a pity, this is impossible. I have infinite life and no one can kill me..."

"Oh, do you really think immortality is a buff?"

Facing the words of the strange man in black, Fang Zheng narrowed his eyes, and a cold light flashed in them.

"I'll soon let you know that immortality is not a Buff, it's a DeBuff!!"

As soon as he finished speaking, Fang Zheng jumped up with a big sword in his hand, and swung it straight at the strange man in black.

"it's useless!!"

The black-clothed weirdo also took out a red sword and blocked Fang Zheng's attack. Then he clenched his fist and punched Fang Zheng. Fang Zheng rolled on the ground and avoided the black-clothed weirdo's counterattack. Seeing this, the black-clothed weirdo sneered, clenched his sword again, and chopped Fang Zheng hard.

At the same time, Fang Zheng pulled out a gun from his arms with his left hand, aimed at the strange man in black and pulled the trigger.

"Bang!!!"

As the gunshots rang out, the black-clad weirdo's body trembled, and he immediately fell to his knees. As he fell to his knees, Fang Zheng stood up, grasped Frostmourne tightly, and stabbed the black-clad weirdo's body again. This time, the huge sword blade directly pierced through the black-clad weirdo's chest, nailing him to the ground. Then, a bone-chilling cold air burst out, turning the black-clad weirdo's body into hard ice crystals.

"Haha, it's useless..."

Although he was frozen, the strange man in black still had no intention of surrendering.

"Even if you freeze me, you can't kill me..."

"I don't want to kill you. After all, I still need to get some information from you."

"intelligence?"

Hearing Fang Zheng's words, the black-clothed weirdo looked at him in confusion. Facing the black-clothed weirdo's puzzled look, Fang Zheng smiled slightly.

"You should know the coordinates of the Imaginary Number Tree."

"you--!!"

Although he was wearing a helmet, the black-clad weirdo's expression could not be seen, but the panic and surprise in his tone could not be concealed. This alone was enough for Fang Zheng to believe that he had found the right person.

“Come in!!”

Without waiting for the strange man in black to say anything, Fang Zheng shouted angrily and suddenly pulled the big sword out of the strange man in black's body. At the same time he pulled out the big sword, several invisible chains sprang out from Frostmourne, tightly wrapped around the strange man in black, binding him up, and then quickly retracted, and saw a spirit burning with flames being torn out of the strange man in black's body, and then swallowed into the blade of Frostmourne.

After losing its soul, the flame behind the black-clothed monster's head also disappeared, and then its body suddenly fell to the ground like a broken toy without support, and then disappeared into the air without a trace.

"Hehe, you can't die, right?"

Fang Zheng raised Frostmourne and squinted his eyes to admire the human figure that was trapped in the blade and howling in pain.

It would be better if he couldn't die. An immortal soul is like a perpetual motion machine. He even hopes to encounter more immortal bosses.

Although according to Fang Zheng's experience, there are actually not many so-called truly immortal beings... Many immortal bosses simply think that they have lived too long and therefore believe that they cannot die.

But a lifespan of just a few hundred or thousand years is not worth mentioning at all when compared to the context of billions of years.

As the strange man in black was dealt with by Fang Zheng, the crisis facing the world came to an end.

Of course, there are problems. In the past, when Akane Shinjo restored the world, she relied on the monster sculptures that released smoke in the city. They were responsible for repairing the entire city after the battle. But this time, the black-clothed monster materialized a large number of monsters, and all the repair monsters in the city were destroyed. Naturally, there was no way for everyone to turn a blind eye and live their lives as if nothing had happened as before.

But...it still has to happen.

Of course, there is also good news. Previously, this world only had this city, because Xin Tiao Qian just stayed here and didn't plan to go out. So the rest of the world was shrouded in fog. Now that Xin Tiao Qian plans to leave this world, she has given up the blockade of this world. As the clouds and reflections covering the surface of the entire world dissipated, the entire world returned to its original appearance.

For the people in this city, they can be said to have suffered an unexpected disaster. In fact, most people still don’t know what happened. They only know that a large number of monsters suddenly came to attack the city inexplicably, and then some people came out to resist the monsters, and then a huge metal battleship appeared and destroyed the monsters... But because the amount of information is too much, they still haven’t figured out what happened.

In other words, except for a very small number of people, others may never be able to figure it out in their lifetime.

But this was not a problem that Fang Zheng needed to deal with. After solving the problem with the monster, Fang Zheng returned to the battleship.

Only this time, there were two more people around him.

"This is Akane Shinjo, this is Rikka Takarada... Well, they will follow us and continue to the Imaginary Number Tree."

Fang Zheng also introduced the two girls to Tesla and the others. Needless to say, Akane Shinjo was supposed to come. On the contrary, the appearance of Takarada Rikka was unexpected. Fang Zheng had not planned to bring her here. However, after learning the cause and effect of the incident and knowing that the monster attack that ravaged their world was done by the Four Heavenly Kings behind the scenes, Takarada Rikka could not sit still and took the initiative to ask to go to the Tree of Imaginary Numbers with Akane Shinjo.

Of course, she herself did not admit that she was a gift, but she said that as a friend of Xin Tiao Qian, she could not leave Xin Tiao Qian here alone. As for that world, it was currently handed over to the boy who could turn into a giant to guard it, and the rest would be dealt with after they solved the problem and everything was settled.

"Hello..."

Looking at the people in front of her, Akane Shinjo smiled and waved to everyone, but Rikka Takanawa bowed respectfully.

"Um... hello, I'm Takarada Rikka, thank you for your guidance."

"Okay, I know your names too."

Tesla was obviously not interested in this boring self-introduction. Instead, she stared at Fang Zheng.

"What's the next coordinate? Have you found it?"

"Found it. This guy is just as I expected..."

Fang Zheng said as he flicked the Frostmourne in his hand. After obtaining the soul of the black-clothed weirdo, Fang Zheng was defenseless against the black-clothed weirdo's experience. So he also learned about the other party's life experience. As expected, from the black-clothed weirdo's experience, he was originally a world consciousness guide in another world similar to the protagonist, but over the long years, he was eroded by the collapse of the imaginary tree and finally became its lackey.

But none of this matters. The most important thing is... the coordinates of the next connection to the imaginary number tree have been found.

Next, it’s time to set off again.

But speaking of coordinates, before that...

"Mei."

Fang Zheng turned his head and looked at Raiden Mei.

"Go give Kiana extra lessons and tell her that if she doesn't score 90 points in math, physics and chemistry in the next exam, just wait and see!"

A Ruler of the Void who can't even grasp the spatial coordinates, isn't this embarrassing? This is absolutely not acceptable. This paramecium must be made to understand what the power of knowledge is!

Thinking of this, Fang Zheng glared at Kiana who was hiding behind Raiden Mei again.

This is not over yet, just wait and see. If you fail the exam, it will be interesting, and I will not show you mercy at that time.
