Walking to the door of Runde Building, Chu Zihang flashed the logo on the box to the security guard at the door, and smiled at them, "Hello, courier company, flower delivery service." Li Su also showed his flower basket, and the calmness of the two made the security guard not suspicious, and smoothly entered the building and walked towards the destination.

After inserting the electronic key into the card slot, Norma quickly cracked the electronic lock, and the two walked into the elevator. The elevator goes straight to the top floor, and the numbers jump at high speed.

Li Su handed something to Chu Zihang, and he fixed his eyes on it, it was a headset. It's not a mission-issued version, it's much larger than that, it can't be tucked into the ear canal, and the headset has half a plastic ring on it, as if to be fixed around the back of the ear.

Chu Zihang looked up at Li Su and found that the other party had a hippie smile as usual, and his face sank like water. "It'll be used." He said with his lips.

Chu Zihang didn't answer, just looked at Li Su, the other party, and stared straight back, the two looked at each other silently, the only movement in the elevator was the number that was beating rapidly.

In the end, Chu Zihang looked away, took the headset and put it on the other ear, he just put it on, the door opened, and it was pouring rain outside.

The rain was huge, but the two of them walked in without care, standing at both ends of the huge electric motors on the suspension bridge, silently looking at the rainy city, waiting for the order of the headquarters far away eleven time zones.

"Let's take the next step." Schneider's voice came through the headphones.

Needless to say, the two already knew, although they couldn't hear the situation on the first floor in the heavy rain, and they didn't know if the school workers were moving, but the motor between the two had been activated, and the rumbling sound meant that the suspension bridge was gradually being lifted off the ground, and eventually it would stop on the twenty-first floor and become a strong backing for the attacking group.

The two of them hung up their rappelling locks and let their bodies tilt and fall from the rooftop, the wind roaring in their ears.

Li Su looked up at the sky and could only see the gray-black iron curtain, as if the end was coming.

In a trance, Li Su felt that he had fallen like this when and where, when his wooden wings were shattered, and all he could see in his eyes was the iron-gray sky and the barren earth, and the fall was so long, so long...... It's lonely.

"Li Su! Report the situation! Professor Schneider's burst of shouting came from the headphones, waking Li Su up.

He didn't slow down as planned, and he didn't move anything after falling into a hallucination. After waking up, Li Su hurriedly slowed down but it was too late, and he fell heavily on the suspension bridge, and the steel cable of the suspension bridge let out a wail that was on the verge of breaking.

"This is Li Su, there is a problem with the lock, I am now on the suspension bridge, and there is no problem with my body."

Schneider breathed a sigh of relief, the point of light representing Chu Zihang on the big screen of the headquarters had slowed down to the twenty-first floor, but Li Su did not slow down at all, and the point of light stopped on the suspension bridge with a slight slowdown in his roar, and Li Su did not know whether he was alive or dead.

"Chu Zihang broke through first, Li Su, you and the suspension bridge went up to meet him."

Fortunately, the impact was not very big, and the original plan was that after Chu Zihang broke in, Li Su was ready to meet him at the entrance of the cave and wait for the suspension bridge to rise, after all, his words and spirit were not aggressive, and the physical measurement data was not otherworldly to the point of Chu Zihang, so his task was to use the "dustless land" to ensure the safety of the retreat route and provide support in case of emergency.

After answering Schneider's words, Li Su sat on the suspension bridge and gasped for air. How does this feel? Originally, Li Su was a person who didn't even dare to play with the jumping machine, and the day he fell into the Three Gorges Dam was a sunny day, and it was impossible to have an iron-gray sky, not to mention what was going on with that wooden wing? I'm not one of those world-changing technology nerds on the Internet, how can I make wings out of wood and fly?

Unable to think of the result, Li Su also knew that now was not the time to be in a daze, so he hurriedly took out the thermal imager from the box, shook it but found that it had been broken, after all, the survival rate of this kind of high-altitude falling precision electronic equipment is indeed low. Li Su shook his head and put it on the suspension bridge, looking up at the big hole on the twenty-first floor, the "masterpiece" made by Chu Zi's aviation electroshock device. He had already risen to the eighteenth floor, and not far away, he could already faintly hear the sound of fighting inside.

In the end, the suspension bridge rose to the twenty-first floor, and before Li Su could go in, he saw a figure jumping out suddenly, it was actually Chu Zihang, he didn't expect those security guards to force him out.

Chu Zihang jumped towards the suspension bridge accurately, and in the air, he glanced at the outside world, and suddenly his breath stagnated, and the change was steep!

There was a shock, and the suspension cable of the suspension bridge was detached from the gears and stuck between the bearings and twisted, and the entire suspension bridge fell sharply.

When he heard the "creaking" sound of the steel cable, Li Su knew that it was not good, and he jumped towards the Runde Building at the same time as the suspension bridge fell. Staggered with Chu Zihang in mid-air, and with a flip of his wrist, there were two more pure black iron rulers on his left hand.

This is his weapon.

Students at the Kassel Academy will be able to choose their own equipment by the second semester of their second year, and those with low blood concentrations will choose firearms to bridge the physical gap when fighting their targets, while the elite will prefer cold weapons, which are more lethal than guns at close range.

Because Li Su had a lot of credits in the first semester, he was also able to choose his own equipment, and finally selected a pair of iron rulers, which were made of special materials to give it strong hardness and toughness, and the black matting treatment allowed it to blend into the watery night at night and turn into a life-seeking grim reaper.

In fact, Li Su's position is not very good, and the piece of glass that Chu Zi avionics broke is some distance away from him horizontally, but it is not a big problem. With his left hand, he pierced the glass curtain wall and fixed himself on it, and at the same time, his right hand threw out a thin rope, and the counterweight on the rope flew towards Chu Zihang. At the same time he shouted: "Don't be in a daze! Our van crashed into the building! ”

Li Su threw it very accurately, Chu Zihang caught it as soon as he stretched out his hand, and then swung towards the glass curtain wall under the pull of the rope. He slammed it on the curtain wall but it didn't seem to have any effect, and after a slight adjustment of his movements, he stepped on the glass and flew up, as if he were walking on the ground.

When he reached the twentieth floor, he kicked sharply, flew sideways to the hole he had made, and rushed in.

After standing firmly, he pulled the rope with all his strength, Li Su did not resist after feeling this pull, kicked the wall and pulled out the iron ruler and hung it on the rope, Chu Zihang brought him into the Runde Building with a sudden lift.

"Awesome." Li Su said this sentence after seeing the situation clearly, which was almost his mantra.

"It is the servant of the spirit of the word," Chu Zihang said, "to strengthen the physical strength of the living body in the realm." In primeval times, the dragons used this spirit to inspire humans and even beasts loyal to them, strengthening them into armies. He also looked at the group of men around him whose skin was oozing blood.

"I'm not talking about them." Li Su said. "I mean you."
