The two men reminisced about their ten years in the military until the sun began to set and the sky began to darken. It was time to act. They stood up carefully and checked their equipment to make sure everything was ready.

At that time, our equipment was not very advanced, and there was a big difference in configuration with the American army. In addition, due to the long journey, the weight of ammunition that the two of them could carry was limited, so Suihe and Li Yichen's rescue operation could only be done by wits, not by force.

Under the cover of darkness, the two men headed towards their target location, weaving through the woods, trying to avoid possible enemy patrols.

After several hours of arduous journey, they finally reached their destination. It was a heavily guarded manor where the kidnapped mathematician was being held. The mathematician had previously conducted research at an institution in the United States, but now he wanted to return home, but the Americans were holding him captive and preventing him from returning.

The mathematician's wife went to the embassy to explain the situation, hoping that the embassy could help her.

After learning of the situation, the embassy immediately contacted China and dispatched two elite personnel to rescue the mathematician. National leaders also attached great importance to this rescue operation. Although our country's equipment and personnel were significantly inferior to those of the American military, they understood that this operation was not only about the safety of the mathematician, but also about safeguarding national dignity and the rights of its citizens.

Suihe and Li Yichen stopped at a secluded location outside the manor and began to formulate a plan of action. A frontal assault was impossible, so they had to rely on strategy and skill. Suihe used his climbing skills to infiltrate the manor and locate the mathematician's imprisonment. Li Yichen, on the other hand, was responsible for observation and cover outside the manor, ready to respond at any time.

In the darkness of the night, Suihe, like an agile leopard, silently climbed the manor wall. Carefully avoiding the patrols' sight, he sneaked into the manor. After a long search, he finally found the room where the mathematician was imprisoned.

Inside the room, the mathematician was tied to a chair, his eyes closed, clearly exhausted. Suihe quickly untied the mathematician and briefly explained the situation. Hearing that someone was coming to rescue him, the mathematician suddenly felt a desire to survive.

Just then, a burst of hurried footsteps were heard. Suihe and the mathematician quickly hid in the dark corner of the room and held their breath.

The patrol stopped at the door and began searching the room. Suihe's heart was in his throat, knowing that if he were discovered, the consequences would be disastrous. Fortunately, the patrol didn't find them and quickly left the room.

Suihe seized the opportunity to escape the room with the mathematician and headed for the manor's exit. Li Yichen was already waiting outside, ready to meet them. After a thrilling escape, they finally managed to escape the manor. Suihe and Li Yichen set out overnight, carrying the mathematician on their backs, evading potential pursuers and skillfully traversing the mountains and forests, bypassing enemy checkpoints.

The mathematician holds important scientific research results and must be sent back to China as soon as possible.

During the arduous journey, Suihe and Li Yichen demonstrated tenacious perseverance and superb fighting skills, escaping danger many times.

Ultimately, they successfully transported the mathematicians safely back to China, where they were commended and praised by their superiors. The rescued mathematicians have made significant contributions to China's development.

This action not only demonstrated our country's strength and determination, but also made an important contribution to the country's scientific and technological development.
