Xiao Mubai stayed in Nanjing for a few days, and made a few phone calls home when he was free, Xiao Ning and his classmates went to play, and the house in Shanghai was empty.

Mom's school is also about to close, waiting for Dad's vacation time to arrive, and then preparing to travel to Europe with the whole family.

The opportunity is rare, my mother forced the task, Xiao Ning also postponed the schedule, and Xiao Mubai didn't dare to make excuses.

Therefore, Xiao Mubai's training is coming to an end. Next week, you have to go on a tour.

However, Xiao Mubai did not expect that a few days after touching the real gun, the long-lost system prompt sounded.

"Congratulations to the commander, you can contact military firearms in reality, and fire 1,000 bullets in a row, trigger the completion of reality hidden mission A, and activate the development of the exchange skill brain domain."

Brain domain development, the most basic primary brain domain development, the points required for redemption are 20 points.

However, after the last mission, Xiao Mubai only had two points left.

This ultimate skill is no longer redeemable.

The development of the primary brain domain has been developed to 30% of the human brain, and the memory has been greatly improved, and the memory speed has become much faster.

In fact, the capacity of the human brain is so large that it is unimaginably large. However, because of memory, we always can't use it well, and many things will be forgotten.

And this kind of brain domain development is to improve people's thinking activity, this kind of improvement, can enhance people's memory, enhance and improve the breadth and depth of people's thinking.

When this skill is put into practice, Xiao Mubai can not only memorize a lot of things, but also learn very quickly, and people will also become smarter.

It's a pity that at present, due to points, Xiao Mubai can't redeem it.

However, the next mission is coming soon, and Xiao Mubai can kill more enemies in this mission, get more points, and then come back.

While Xiao Mubai was waiting, the fifth mission came.

It was Sunday morning, November 14, 1965. The location is the base of the Vietnamese U.S. Army in Polemen, and Xiao Mubai descended and descended to this time and space.

Xiao Mubai's identity is an American GI, named Jack Edward, who is an ordinary sergeant squad leader in the first battalion of the 7th Cavalry Regiment of the 1st Cavalry Division of the US Army and an ordinary sergeant squad leader in the 3rd squad of the second platoon of B Company.

The background is the Vietnam War, the Battle of Poleme, the Battle of the Derang Valley.

The Vietnam War was a decade-long war between South Vietnam, the United States and North Vietnam. Among them, the Democratic Republic of Vietnam, referred to as North Vietnam, is supported by China and the Soviet Union. The Republic of Vietnam, or South Vietnam for short, is supported by the United States, which is dominated by the NATO bloc.

What began as a confrontation between North and South Vietnam as a proxy war between NATO and the Warsaw Pact turned into a direct war between North Vietnam and the United States.

The United States mobilized 500,000 people to directly participate in the war.

The Vietnam War was a war in which the United States suffered the greatest losses, exhibited the largest scale, and suffered the largest number of casualties since World War II.

The Battle of the Delang Valley, a battle fought during the Battle of Poremen.

The valley of the Derang, thirty kilometres south of the town of Poleme, is about to break out in a fierce battle that will last for three days.

The U.S. troops involved in the battle were the 1st Battalion of the 7th Cavalry Regiment of the 1st Cavalry Division, commanded by Lieutenant Colonel Moore, with a total of 395 men.

The North Vietnamese Army was the 33rd, 66th, and 320th Regiments of the Vietnamese People's Liberation Army under the command of Lieutenant Colonel Nguyen Huu An, and the H-15 Battalion of the Viet Cong guerrillas.

After three days of fierce fighting, the Vietnam People's Army lost 1,037 casualties and the US Defense Forces lost 234 casualties, ending in a draw.

Xiao Mubai, as Sergeant Jack, will fight here for three days until the end.

The task of the system is to lead the whole class of soldiers to continue to fight until the end of the battle, and the combat attrition cannot exceed one-third.

Of course, Xiao Mubai himself has to live and spend these three days.

Xiao Mubai has an understanding of this situation, Baidu Encyclopedia and WikiLeaks have read it, and other detailed information cannot be found on the Internet, and there is a book written by an American "The Loyal Soul of the Vietnam War", this book Xiao Mubai has only read a little.

The mistake of the early intelligence and reconnaissance work, the failure to find out the situation of the surrounding North Vietnamese Army, and the erroneous estimation of the strength of the North Vietnamese Army, led to the North Vietnamese Army being encircled as soon as it landed, and the strength of the North Vietnamese Army was several times weaker, and the North Vietnamese Army was repeatedly blocked. After the American soldiers landed, they did not find out the enemy's situation, and the soldiers fired indiscriminately everywhere, not only wasting ammunition, but also attracting the enemy's attention.

In addition, the second platoon found a soldier of the North Vietnamese Army, pursued him without asking for instructions, got into the trap set by the North Vietnamese Army, and was ambushed by the North Vietnamese Army, suffering heavy casualties, for which Lieutenant Colonel Moore had to send someone to rescue.

In addition, the suicide attack of the Black Widow in Vietnam also caused heavy losses to the US military. When the Vietnamese woman with her breasts and breasts did not cover her body, she walked over and quietly opened the safety of the grenade hidden in her waist, and in an instant, the flesh and blood flew everywhere, causing the American soldiers who relaxed their vigilance to suffer heavy losses and pay the price for their frivolity.

There is also the U.S. Air Force that accidentally bombed its teammates, and the B-52 bomber carrying napalm* bombs, after covering the North Vietnamese position, mistakenly dropped the bomb on the U.S. position, and the burning man struggling in the sky was fixed in everyone's sight.

On 14 July, the 320th Infantry Regiment of the North Vietnamese Army, which was responsible for the ambush mission, had set off first, and the 66th and 33rd Infantry Regiments were completing their assembly and preparing to start moving.

The commander of the North Vietnamese Army at the scene was Lieutenant Colonel Nguyen Huu An, deputy commander of the B-3 Military Region, who was ambitious to encircle and annihilate the American army.

"You are heading towards a valley of death, where you will only see the backs of those around you, and he will look at you as well. You don't care what color he is or what his name is. We will face some fierce and stubborn enemies. I can't promise to bring you home alive. But I swear that when the war starts, I will be the first to reach the battlefield. ”

Before leaving, Lieutenant Colonel Moore said to the soldiers of the first battalion.

Lieutenant Colonel Harold G. Moore is commander of the 1st Battalion, 7th Cavalry Regiment, 1st Cavalry Division, United States Defense Forces.

It was also this three-day battle, the Supreme Commander of the US Army.

These, in addition to Xiao Mubai's own knowing, are also provided by the system.

In fact, the information that the system told Xiao Mubai was limited, and it was impossible to tell Xiao Mubai all the information. Moreover, Xiao Mubai is skeptical about this information, and all this information needs to be confirmed one by one.

If the intelligence goes wrong and a small accident occurs, it will become a fatal mistake in a tense battle, and the mistake will inevitably cause losses, and someone needs to pay for it.

Xiao Mubai doesn't want the person to pay the bill to be himself.

You can't pin all your hopes on others, you can only rely on yourself.
