Siheyuan: Sap is the last word

At the end of the street, a huge pedestrian tank drove slowly. This tank is different from traditional military tanks. Its appearance is more like a moving castle, decorated with ancient ornaments and mysterious symbols. The surface of the tank is covered with exotic plants, exuding a refreshing scent.

The red-haired guy frowned and said, "What kind of manned tank is this? It seems to be a fusion of ancient civilization and modern technology."

He Yudong also felt a little curious. He said to the team: "We want to find out. Maybe this is a form of transportation in the city, or a combination of ancient civilization and modern technology."

The expedition team approached the pedestrian tank, and the door on the vehicle body slowly opened, revealing a human in ancient clothing. There was a veil of mystery on their faces, and curiosity about the expedition was revealed in their eyes.

"Welcome to our city," the leader-like human said, his tone full of courtesy and enthusiasm, "I am the guardian of the city. We saw your exploration of the city, so we came here to greet you."

When the expedition team heard this title, they all exchanged glances. Guardians of the city, this title made them think about more mysteries of the city.

"Mr. Guardian, we are very curious about this city," He Yudong expressed their purpose, "Can you share some history and culture about this city?"

The guardian smiled, invited the expedition team to enter the pedestrian tank, and started an in-depth communication about the city. Inside the pedestrian tank, the expedition team discovered a mobile library containing precious documents about the city's history, culture and technology.

During this exchange, they gradually learned that this city has a long history of civilization. It is a combination of ancient wise men and modern technology. It is a city based on the concepts of harmony, exploration and integration. The pedestrian tanks took them to every corner of the city, revealing the strangeness of the city that was unknown to the outside world.

In the human tank, the members of the expedition team had an in-depth conversation with the city's guardians. The Guardians introduced them to the city's unique technologies, including manned tanks, moving buildings in the city, and a civilization that could live in harmony with nature.

“Our city is constantly innovating,” the Guardian said proudly. “We are integrated with nature while using advanced technology. This is the key to our ability to maintain peace and prosperity.”

The red-haired guy looked at the flowing scenery outside the window. He couldn't help but sigh: "This is really an amazing city. I have never seen a civilization that combines tradition and modernity so skillfully."

He Yudong was also deeply attracted. He asked: "The realization of all this is inseparable from the efforts of urban residents, right?"

The guardian nodded with a proud smile on his face: "It is precisely because of the efforts of every resident that we can maintain the harmony of this city. Everyone performs their duties and strives to create a better future."

The members of the expedition team were filled with emotion. They began to realize that the reason why this city is so unique and progressive is not only because of the development of science and technology, but also because of people's hard work and creativity.

Guided by pedestrian tanks, the expedition entered the industrial area of ​​the city. There are busy workshops here, with machines humming in operation. The guardian pointed to the workshop and said to the expedition team: "This is our innovation center, where all kinds of new technologies are born."

In the huge laboratory, the expedition team discovered a variety of amazing inventions, including energy devices, intelligent robots, etc. The application of these technologies makes cities more convenient and improves residents' living standards.

“We don’t like to be idle,” the guardian said with a smile. “Innovation and progress are the cornerstones of our civilization. Every resident is involved and working hard for the future of the city.”

In every corner of the city, the expedition team felt a vibrant atmosphere. The city seems to be an ever-evolving laboratory, with the Guardians leading the way.

"We still have many places we want to show you," the guardian invited the expedition team, "Don't be idle, let us go and see more miracles together."

While exploring the city, the expedition is led to a massive structure that stands in the heart of the city. This building is different from others, towering into the sky and unique in shape. It seems to be a scientific research center with huge annexes.

"This is our giant annex research center," the Guardian proudly introduced, "where the most advanced technology and innovation in our city gathers."

The door to the huge annex research center slowly opened, and the expedition team was led into a spacious and modern hall. It is fully equipped with various complex instruments and screens, which is breathtaking.

“Our research team has been committed to exploring a broader scientific field,” the guardian said. “This is the core area where we pursue knowledge and expand the boundaries of science and technology.”

Members of the expedition walked the halls, observing various experiments and research. The presence of the giant annex shocked them, and the city not only focused on harmonious symbiosis, but also continued to expand the possibilities of technology.

He Yudong looked at a giant experimental device, and his curiosity about science surged in his heart. He told the Guardian: "It's all incredible. How does this city achieve such high-tech and harmonious symbiosis?"

The guardian responded with a smile: "Our civilization has always maintained an open mind and absorbed a variety of ideas and innovations. Through continuous research and practice, we have been able to achieve today's achievements."

In a corner of the hall, the expedition team discovered a door leading to an underground laboratory. The guardian motioned for them to follow, and they walked through the passage to a mysterious underground space. This is the heart of a vast annex, a research field filled with unknown powers.

"This is our deepest exploration," the guardian said mysteriously. "The experiments here will help us better understand the mysteries of the universe."

The expedition team found themselves in this mysterious underground laboratory and faced a variety of unusual technological equipment. He Yudong's heart was filled with a thirst for knowledge, and he was eager to have a deeper understanding of the city's technological mysteries.

"Everyone, be careful!" He Yudong shouted loudly. He frowned slightly, his resolute eyes revealing a firmness.

Fighting broke out, weapons and the roar of the infected mingling. He Yudong's skills are flexible, and every swing carries firm power. The team members cooperated tacitly. Some used long-range shooting with long guns, while others fought hard at close range. The battle is a relentless dance, every movement a pursuit of survival.

Gradually, the roar of the infected became fainter and eventually disappeared into the dust. He Yudong gasped and glanced at the body of the defeated enemy. This is just a small step in an endless escape, but for them, every victory is an affirmation of the future.

As time passed, He Yudong's team discovered an abandoned laboratory forgotten by time. Deep in the laboratory, they found some strange experimental records, mentioning a mysterious plan called "projectgenesis".

“What the hell is this?” A team member pointed at the record with his eyes widened in curiosity.

He Yudong frowned, thinking about the ins and outs of all this. He began to feel that there might be a more unfathomable secret hidden behind this apocalypse. The world seems to be a huge puzzle, and they are just an insignificant part of it.

Walking through the deserted city, He Yudong and his team gradually felt tired. The long flight made everyone tired. They came to a corner of the city abandoned by time and saw an old building. The building had apparently once been a medical center, and the glass on the door was broken, but a spooky light shone through.

He Yudong stopped and looked around. "Maybe we could take a break here," he suggested, and the others nodded in agreement. So, the team walked into this strange and dark space together.

Entering the medical center, they smelled a pungent smell of medicine. Under the dim light, it looked even weirder. He Yudong directed everyone to look for supplies and possible hiding places. In front of the cluttered medicine cabinet, he found a box of old-fashioned first aid kits.

"There are some medical supplies here that may help us treat some wounds." He Yudong said, he bent down and picked up the medicine box.

Just then, a low groan came. Everyone suddenly raised their heads and saw a group of infected people with weak limbs, as if they were troubled by something and unable to stand. They moved slowly towards He Yudong and the team, with eager expressions on their faces.

"What's wrong with these guys?" one team member asked confused.

He Yudong frowned and looked at the infected person whose limbs were weak. Their eyes revealed a deep helplessness and pain, as if they were under some strange influence. This made He Yudong feel a little uneasy, and at the same time stimulated his desire for the truth behind this doomsday.

"We have to be careful, maybe it's not as safe as we thought." He Yudong said, handing the medicine box to a team member. "We need to get out of here as soon as possible."

He Yudong and his team walked through the ruins of the city, left the medical center, and continued their escape. Their goals have become vague and difficult, and they can only look for hope in areas that have not been affected by the doomsday. Gradually, they came to a vast salt-alkali land. The ground is completely white, and the sunlight shines directly on the saline-alkali land, reflecting a dazzling white light. He Yudong felt thirsty. This saline-alkali land seemed to be another test on their way to escape.
