Siheyuan: I, He Yuzhu, beat up all the beasts!

Just as the two were about to leave the market and continue their environmental protection journey, a hurried figure stopped them.

It was a courier in uniform, holding a package in his hand, and he said breathlessly: "Mr. He... Mr. He, this is your package. It's an urgent document. Please sign for it in person."

He Yuzhu took the package doubtfully, opened it and saw that it was an invitation letter from an international environmental protection organization, inviting him and the teenager to attend the upcoming Global Environmental Protection Conference and speak as representatives of young environmental pioneers.

"Uncle He, is this true? We are going to share our stories and ideas on the international stage!" The boy was so excited that he almost jumped up. The sudden honor made him nervous and excited.

"It seems that our efforts have been recognized by the world." He Yuzhu's eyes sparkled with pride. "This is not only an opportunity, but also a test for us. We must be ready to bring our voice, China's voice, to every corner of the world."

The two smiled at each other, their hearts filled with an unprecedented sense of mission. They knew that the road ahead was still long, but as long as there was light in their hearts, there would be a way under their feet.

"Well, let's get ready to go, young man. This time, we want to show the world that every small action can be combined into a force to change the world." He Yuzhu's words were firm and powerful, as if declaring their determination to the whole world.

"Yes, Uncle He, let us work together and go all out for this planet and our future!" The young man clenched his fists, the flame of dreams burning in his eyes.

As the date of the Global Environmental Conference approaches, He Yuzhu and the teenagers begin intensive preparations. They study materials and write speeches day and night, striving to present their understanding and vision of environmental protection to the world in the most sincere and moving way.

"Uncle He, I think this section on ecological balance can be further developed by adding some real-life examples, such as how the town we helped, which was almost deserted due to pollution, regained its vitality with everyone's efforts." The boy pointed to a section of the speech and made a serious suggestion.

"It's a good idea. This will not only show the seriousness of the problem, but also show the solution and give people hope." He Yuzhu nodded in agreement, and then the two of them immersed themselves in the revision, carefully considering every word and sentence, striving for perfection.

On the day of the conference, the venue was packed with environmentalists, government representatives, scholars and media from all over the world. He Yuzhu and the teenager stood backstage, nervous and excited. At this time, a staff member came over and reminded them that they were about to go on stage.

"Mr. He, young people, are you ready? The whole world is waiting for your voice." The staff's voice was encouraging.

"We are ready." He Yuzhu took a deep breath, patted the boy on the back, and the two walked towards the center of the stage side by side.

The lights were focused and the applause was thunderous. He Yuzhu spoke first. His voice was steady and infectious. He talked about how they started with a small idea and gradually gathered the strength of all sectors of society to promote the development of environmental protection. Then, the teenager took the microphone and shared the challenges they encountered, the touching moments they gained, and their infinite vision for the future of environmental protection in his passionate and hopeful tone.

“We believe that environmental protection is not a burden but an opportunity, and it is a change that everyone can participate in. It concerns you and me, future generations, and every life on this planet.” As the boy finished speaking, warm applause broke out in the venue. Many people had tears in their eyes, touched by this youthful enthusiasm.

After the speech, the two were interviewed by global media. A foreign reporter raised his hand and asked, "Mr. He, young man, your success has inspired many people, but facing such a huge environmental problem, have you ever felt powerless or desperate?"

He Yuzhu smiled and replied: "Of course, we will also have difficulties and setbacks, but every time at this time, we will think of those people who have regained their smiles because of our efforts, and those rivers that have become clearer because of our persistence. It is these small but real changes that give us unlimited strength and hope."

The boy went on to say, "Moreover, we are never alone. Look at everyone here today, everyone who cares about environmental protection. We are a strong collective. As long as we work together, there will be no difficulties that we cannot overcome."

After the interview, the two walked out of the venue and were surrounded by a group of enthusiastic participants. A middle-aged lady held He Yuzhu's hand tightly with tears in her eyes: "Thank you for giving me hope. I decided to join the local environmental protection organization after I return and contribute to the best of my ability."

"Your support is the greatest encouragement to us," He Yuzhu responded warmly, "Every heart willing to change is a beacon that illuminates the future."

At this time, a young volunteer squeezed through the crowd and excitedly said to the teenager: "I have been following your project and I am really inspired! I am developing an app that I hope will help people record their environmentally friendly behaviors in daily life, accumulate (green points'), and redeem environmentally friendly products. What do you think?".

"Great!" The boy's eyes lit up. "Such an idea can make environmental protection more interesting and more practical. We are happy to cooperate with you to promote it together."

The communication and sharing among the crowd continued to heat up, and He Yuzhu and the teenager became a bridge connecting the seeds of environmental protection in everyone's heart. Their stories, like the wind, have spread to every corner of the world, inspiring more people to take action.

Just as they were about to bid farewell to the enthusiastic crowd and continue on a new journey, a mysterious old man slowly approached them. His eyes were deep, as if he could see into people's hearts.

“Young people, you have done a great job.” The old man’s voice was gentle but powerful. “But the real challenges are still ahead. The future of the earth requires more innovation and courage.”

He Yuzhu and the young man looked at each other, their hearts filled with curiosity.

“Excuse me, who are you…?” the boy asked cautiously.

The old man smiled and did not answer directly. Instead, he took out an antique diary from his arms and gently placed it in He Yuzhu's hand.

“It contains some ancient wisdom and unsolved mysteries, which may provide different inspiration for your environmental protection journey. Remember, protecting the earth is not just a matter of technology and policy. There are deeper natural laws waiting for you to explore.”
