Zhiwu is the main helicopter equipped by the People's Liberation Army, imitating the Su-style Mi4 helicopter, using a piston engine with backward technology, with a simple shape and looks like a distant country cousin of a Mi24 female deer, but for the ground infantry, it is still an invincible existence like a dragon.

Three helicopters flew in the shape of a font. One hovered at a high altitude to reconnaissance, the other flew eastward, and the third landed on the open space of the river beach. Before it could even settle, armed soldiers jumped out of the side door of the cabin. Yishui's M65 jacket, brown beret, holding an M16A1 automatic rifle, and high-tube military boots under his feet. This is a standard US military outfit, but these people have yellow faces.

"All-American-equipped aircraft landing scouts." Party Patriotic put down his telescope and whispered, "There is no record of such troops in history books."

The six people in the crossing group were hidden in the woods and dared not speak. They walked in a hurry and only brought two Type 56 submachine guns, with limited magazines. The enemy had helicopter air support. If three Zhiwu were loaded with infantry, there would be thirty people, with a 5-to-one advantage, and this battle would not be able to be fought.

The group of brown berets looked around the burning remains of Yunwu. A man with an officer-like appearance issued instructions to the other two helicopters using a step-by-step talk aircraft. He knew without guessing that he would be able to catch up and block the crossing team.

"Thunder and fiercely open the way, Yu Hanchao cut off the rear and withdraw." The Party gave the order.

Yunwu crashed on the south bank of the Yangtze River, with a rolling river standing in front of you, with interceptions in front of you and pursuers behind you. The team was desperate and could only go to a steep mountain in front of you. According to the surrounding geography, this place should be the famous Xisai Mountain. Since ancient times, countless wars have occurred here.

Xisai Mountain is steep, with an altitude of 176 meters and a circumference of 18 kilometers. Although it is not as good as the majestic and continuous mountains like Mufu Mountain and Dabie Mountain, it is still more than enough to hide a few people. Lei Meng is tall and strong, and he waves a dagger to open the way in front. After Yu Hanchao's gun hall, the rest of the people march in the middle. Professor Xing is old and has difficulty walking, and he is so breathless after walking a few steps.

"I'll carry you." Liu Yanzhi bent down, but Zhuzi snatched the lead. Professor Xing hesitated for a moment and chose to lean on Zhuzi's back.

The six people quickly marched towards the top of the mountain. Xisai Mountain was full of trees and helicopters were hovering above their heads, but they could not see the people in the forest. However, this was not a problem for experienced pursuers. They could calculate the general range of the target based on time and the speed of the individual soldiers' advancement, and they could not escape from the range of three kilometers.

The brown berets chased each other very tightly. Liu Yan directly replaced Yu Hanchao's guard duty and lay on the hillside to block the enemy. He used a captured AKM automatic rifle with a precision better than the domestic 56 rushing. He pointed and hit him wherever he pointed at a distance of 400 meters. When he used his sight guard to draw an enemy, he found a familiar face, and there was John Lynch in the pursuit.

Lao Lin's dress is different from others. He is wearing sunglasses, chewing gum, holding the Liberation Cap on his head with his hands, and carrying an AK series automatic rifle with a folded short barrel. He is full of shouting and shouting, "Why did Lao Lin appear, why are the pursuers American equipment, and they are mobilized by US fighter jets?" Then there is only one possibility. The CIA knows that the time travel team took away the scientific research results of the Ninth Machinery Department, which means that someone in the team leaked the secrets.

The Party and the U.S. leader is the team leader, and it is impossible to take the initiative to leak the secrets. All the remaining three people are possible, but in terms of motivation, Professor Xing is the most suspicious because he is the only one who has experienced this special historical stage.

In a blink of an eye, John Lynch's figure disappeared. The pursuers were very careful and tried not to expose their bodies to the enemy's sight. Their team was even equipped with snipers. Liu Yanzhi could feel the cold light of the scope. He stood up and retreated, paying attention to the treetops and the ground. Sure enough, every distance, there were broken branches, buttons, cloth and other markers on the ground.

After a rushing march, Dang Aiguo stopped, wiped the sweat from his head, and looked back and saw that everyone in the team was there, but Liu Yanzhi was not seen. He asked Yu Hanchao, who shook his head blankly: "I saw him just now."

As soon as he finished speaking, the branches and leaves in front of him were shaking. Liu Yanzhi fell from the tree, his movements were as light as a monkey.

"Lao Lin and his people were led to the opposite direction by him." Liu Yan said straight, his eyes swept over Professor Xing.

Dang Aiguo is a person with high IQ. His eyes also fell on Professor Xing and asked calmly: "Old Xing, why do you want to betray us?"

"I didn't, it was wrong." Professor Xing subconsciously refuted, but soon he realized that this was futile, because the rags in Liu Yanzhi's hand could match the ripped holes in his clothes.

"You said you had a stomachache, but you actually called Lao Lin." Lei Meng also noticed something was wrong and glared at Professor Xing fiercely, "Old thing, we are not sorry for you!"

"Yes, I did make a deal with Lynch, but I didn't betray you. If you can't escape, hand over the pillars and they will let you live." Professor Xing finally told the truth, with a calm expression, as if he was not a traitor, but a righteous revolutionary.

"Can you tell me why? It's hard for me to understand that you became a traitor for 50,000 US dollars." Party Patriotic was very calm and pried open the hammer of the pistol.

"Not for money, but for myself." Professor Xing smiled bitterly and said frankly, "For my young self, I have lived a frustration in my life. I was originally from a scholarly family, and my parents were both international students. I should have a great future, but because of the damn politics, I was suppressed by those poor and lower-middle peasants all my life and could not stand out. My life is over, but in 1970, I still have a lot of opportunities. If I go to the United States, I will go to a prestigious university, become a professor, marry an overseas Chinese wife, have a big house, two children and one dog, and travel around the world after retirement."

Suddenly he changed his mind and widened his eyes: "Instead of being an associate professor at the age of 70 square meters, living in a dormitory building with no children, rolling his eyes, and following you to risk your life to travel through time and space. But it's okay, you gave me the opportunity to change my destiny. It doesn't matter if I die, the young Xing Jianzhong can live well for him."

Lei Meng took a step forward, and the dagger was placed on Professor Xing's neck. He turned his head and said to Dang Aiguo: "The shooting is too loud, I'll send him away."

Dang Aiguo nodded, and Lei Meng was about to use the knife, but Professor Xing suddenly pulled out a grenade from Lei Meng's waist with a quick move that was not consistent with his age, and quickly pulled out the insurance pin. At the critical moment, Liu Yanzhi kicked Professor Xing and the grenade down the hillside.

Xisai Mountain is dangerous and the hillside is steep. Professor Xing disappeared in an instant. A roar came from the foot of the mountain and the grenade exploded.

The explosion exposed their traces, and the helicopters flew in. First, a machine gun fired, fire reconnaissance, and then hovered in the air. The soldiers landed along the ropes one by one, surrounding them from three directions. The remaining side was the cliff facing the Yangtze River.

The loudspeaker on the helicopter heard a voice of persuading the surrender: "Don't resist unnecessary things anymore. You can't escape. Surrender. I can give you the best conditions."

A figure appeared on the cliff, holding his hands high, and the helicopter landed, hovering in the air parallel to the cliff. The side door of the cabin opened, and the Chinese paramilitary personnel from the CIA held the M16 rifle and aimed at the man, identifying his identity.

"Stand there and don't move, someone will pick you up immediately..." The shouting on the helicopter was not over yet, and the man suddenly burst out, accelerated his sprint, rushed to the cliff at a speed that ordinary people could not imagine, jumped up, and landed in the cabin like lightning. The personnel in the cabin were caught off guard and were knocked out by a punch from the flying man. Zhiwu's cockpit was one floor higher than the crew cabin. The two pilots noticed that something was wrong and quickly pulled it up, but it was too late. Liu Yanzhi appeared behind them, holding a black pistol in his hand.

The situation reversed dramatically. The helicopter pilot hovered above the cliff under Liu Yanzhi's coercion. A nylon rope was thrown out from the cabin. Dang Aiguo and others quickly climbed up, and they all breathed a sigh of relief. Lei Meng was used to it, but Yu Hanchao and Zhuzi both looked at Liu Yanzhi with extremely respectful eyes. This skill was something they could never learn in their lives, and it had exceeded the limit of the ability that the human body could reach.

The pilot was expelled and replaced by Liu Yanzhi and Dang Aiguo flying the helicopter. The other two helicopters did not notice anything that happened here, which gave them the opportunity to attack. The wings captured were equipped with a rocket nest under the wings, and the firepower was extremely powerful.

John Lynch and his subordinates found Professor Xing, who was covered in bruises on the hillside. He had thorny wounds, shrapnel scars, bloody head and bloody face, and he was already dying and out of help.

"Lao Lin, do our transactions still count?" Professor Xing asked in a weak voice.

"Accounting." Lynch said, then added, "If you didn't lie to me."

"I'm going to die, I won't lie to you. I have a secret to sell it to you." Professor Xing's voice became weaker and weaker, "Actually, we are from 2017..."

"What did you say? Be louder." John Lynch put his head to Professor Xing's mouth, but only heard the seemingly nonsense stuttering. He raised his head and looked again. Professor Xing's eyes were open, and his breath was gone.

A violent explosion came from the air, and a helicopter was blown up by a volley. Another Z-5 was knocked out. The third responded quickly. Two helicopters launched fierce air combat in the air. The artillery and rockets flew together, and the tracer bombs pulled out red arcs in dusk.

In the end, they won the team through the team. They flew to the east in a helicopter, with bloody sun behind them, and thick smoke rolling on Xisai Mountain.
