The mighty troops drove towards the research institute at high speed.

Such a big action was quickly discovered by the helicopter and was soon reported to Zhao Er and Fan Bufan.

Fan Bufan immediately asked Heisenberg and Dr. Hahn: "Doctor, how long will it take to finish collecting the materials and ores?" ”

Heisenberg and Hahn said: "With the current situation, it will take about 2 hours, and if you add the equipment, it will take 5 hours. ”

After hearing this, he immediately said: "Abandon all the equipment, just bring the data and ore." Everything goes through here, transported through. ”

After speaking, Fan Bufan opened the door of time and space, and Heisenberg and Hahn were shocked: "Artificial wormholes, there are people who can artificially create wormholes, my God, is this God's masterpiece, please allow us to study it carefully, is it okay?" ”

Well, the brain circuits of scientists are really different, and they are still thinking about this at this time.

Fan Bufan said: "You hurry up and pack your things, the enemy is about to arrive, and when you go back, I will let you study it well." ”

Leaving the gate of time and space, Fan Bufan informed Zhao Er that he could retreat if he insisted for three hours. An extra hour, just in case.

After Zhao Er received the order, he ordered the helicopter to start harassing the US troops, giving priority to attacking the opponent's armored vehicles.

The helicopter began harassment tactics through night vision devices, circled the armored units, and started a guerrilla attack.

This time, the U.S. military is not like the previous U.S. troops who were sleepy, and they were always vigilant against the enemy's situation.

Soon the roar of the helicopter reached their ears.

The helicopters did not wait for the approach to start the strike, and the armored forces were stunned, they never expected that there would be air units at night that could hit them so accurately.

However, their commander quickly reacted and immediately organized anti-aircraft fire, erected anti-aircraft nets, and struck the enemy with numbers.

Well, such a counterattack was in place, the helicopter could only stretch the height and began to counterattack with anti-tank missiles.

Each helicopter can carry 4 anti-tank missiles, 16 helicopters, which theoretically can destroy the troops of two tank battalions.

However, after Zhao Er ordered them to keep two anti-tank missiles for each helicopter, the helicopter counterattacked, and the US troops who were instantly destroyed a tank battalion were desperate.

No matter how this battle was fought, he had already suffered heavy losses without seeing the enemy.

However, the high-ranking officers, who knew the inside story, still ordered to move on, and the helicopters saw that the enemy was not scared away, so they could only continue to harass them from a distance.

The commander breathed a sigh of relief when he saw that the other party had reduced the intensity of his attack.

The order continued to increase anti-aircraft fire to prevent the enemy from attacking.

After Zhao Er heard the report of the helicopter unit, he ordered all the tanks and armored vehicles to move up and advance towards the enemy.

The passive defense will only become more and more passive, so Zhao Er decided to take the initiative.

The T72 had an infrared periscope and a long range, and they opened fire on the American armored forces first.

Well, the armored forces of the US army were once again stunned, and the concentrated fire of a tank battalion struck them, which caused them heavy losses.

And now they can't see anything, with the front lights of the tank, they have a limited distance. So, none of them knew what the enemy was.

The American commander had no choice but to call for support, but he understood that even so, it was useless not to find the enemy.

However, at this time, his adjutant made a note: let the mortar guns of the infantry units fire flares.

The commander agreed, and immediately ordered all mortars to fire flares.

When the first flares were fired, the T72 was supposed to be blinded briefly by a sudden bright light.

And at this time, the U.S. military also discovered their enemy, a tank unit that did not belong to this era.

Seeing the enemy, all the American tanks, began a counterattack.

Several times the enemy did not see it, many comrades-in-arms were killed, which made them hold back the fire in their stomachs for a long time.

So they became angry. There was a loud bang, and the American tank fired a shell.

Unfortunately, what made them desperate was that the poor artillery fire of the M4 Sherman could not penetrate the 200mm armor in the front of the T72 at all.

Only a few tanks were broken tracks and could only be used as stationary batteries for the time being.

Several T72s were also hit in the fuel tank due to angle problems, causing the soldiers inside to be burned alive.

Zhao Er was very angry when he saw someone killed or wounded, but he knew that he was on the battlefield and there would inevitably be casualties.

So Zhao Er ordered the tanks to continue the counterattack, and at the same time ordered the helicopters to strike at the opponent's mortar gun positions.

The recovered tank troops were very angry when they saw their comrades burned to death, and immediately began to counterattack when they heard Zhao Er's order.

The helicopter received the order and began to operate to strike at mortar positions.

Seeing this, the commander of the US army immediately ordered all the mortar groups to disperse and move immediately after firing a round of flares.

Seeing this, the helicopter could only run for its life and hit them like rats.

After Zhao Er saw that his helicopter was dragged by the machine gun team, he immediately decided to abandon them. Concentrate forces against the U.S. tank units, and order the tank units to rush into the U.S. units and mix with the U.S. forces.

At the same time, the armored vehicles were ordered to lay down the soldiers and strike at the opposing infantry units to cover the tanks. At the same time, armored vehicles also cover infantry and tanks.

This was done to prevent the enemy's artillery fire, mixing together, and unless the commander of the opposing side was ruthless enough to destroy it with his own troops, he would have to give up artillery support.

When the U.S. commander saw the troops fighting together, he regretfully gave up the walkie-talkie in his hand.

As Zhao Er expected, he was indeed ready to let the artillery fire directly cover the blow and destroy the enemy.

Now that the two sides are fighting together, they can only rely on their strength, and Zhao Er and they are better equipped than others. The U.S. military, on the other hand, won numerically, and the two sides were evenly matched.

And the helicopter was now useless in this melee, so Zhao Er ordered them to intercept the troops behind.

Although the soldiers on Zhao Er's side were well-equipped, they were all new recruits, and they were on the battlefield for the first time, so it was inevitable that there would be mistakes, so there were serious casualties at the beginning.

However, with good training and well-armed weapons, the soldiers, who quickly stabilized, began to counterattack.

Once upon a time, the U.S. military relied on such tactics to defeat one enemy after another.

Now, they have tried the bitter fruit of this tactic as well.

On one side, it relied on the number of people, and on the other hand, it relied on equipment, so the two sides fought a stalemate.

The armored vehicles relied on their mobility and firepower to beat the American infantry crying and crying for their mothers. But from time to time, they used bazooka bazooka to sneak attack, and the armored vehicle units began to suffer casualties.

Now the troops on both sides are all stuck together, and they can't retreat if they want to.

Zhao Er was very anxious when he saw this situation, because if this continued, they would be killed by the other party sooner or later, and the other party's support could arrive at any time, and they would be in danger at that time.

Seeing that there was still an hour and a half to retreat, Zhao Er gritted his teeth and continued to persevere.

In the research institute, seeing the flames on the battlefield, Fan Bufan was very worried about Zhao Er and them.

Their first enemy was so strong, even if they were well-armed, but after all, they were recruits, and Fan Bufan was still very worried.

As a result, Fan Bufan could only ask them to speed up the transfer of materials.

He also flew, ready to see how the battle fared now.

When I came to the sky above the battlefield, I saw the troops of both sides glued together. Seeing the countless casualties on his side, Fan Bufan was still very distressed, after all, he had cultivated it with great difficulty.

So, Fan Bufan decided to find a way to help his soldiers.

However, it is useless to go to the battlefield even if he alone is on his own, so he can only find another way. The thief captures the king first, so Fan Bufan decided to deal with the other party's commander.

So, he took the night vision device and started looking for it.

Soon Fan Bufan found a tank that was independent and outside the battlefield, and Fan Bufan thought that it should be the one.

Fan Bufan aimed at the tank and used his telekinesis to impact him.

With a bang, the tank shook. Seeing this, Fan Bufan continued to impact until the tank was knocked on its side.

Seeing that no one came out, Fan Bufan estimated that the people inside should have fainted.

So Fan Bufan looked at the battlefield again, but unfortunately there was no change.

Come to think of it, it's almost a hand-to-hand battle now, and it's actually the same with or without a commander.

Fan Bufan is also sitting on wax now, and he has no choice but to return to the research institute again, urging Heisenberg and them to move the materials quickly.

When Heisenberg heard this, he said: "Sir, we are already speeding up, many unimportant materials have been discarded, and other materials have been almost moved. The remaining ore is still being transported due to high radiation. ”

Fan Bufan thought for a while and said, "Give up the ore immediately, everyone immediately withdraws, and we leave here." ”

When Heisenberg and Hahn heard this, they agreed. Then everyone entered the portal with the loaded supplies.

Fan Bufan looked at the research institute and sighed. closed the door of time and space, then took out the walkie-talkie and said, "Zhao Er, immediately prepare to withdraw from the battlefield, let's withdraw." ”

Zhao Er breathed a sigh of relief when he heard this, and then began to issue orders.

He first ordered the helicopter to return to defense, and when the helicopter returned, let the tank armored vehicle cover the infantry and the crew of the wounded tank armored car that could not walk on board.

Then let the helicopter start to divide the battlefield, and lock on all the remaining anti-tank missiles to the target and launch.

Because of the sudden strong firepower, the US army was stunned, and taking this opportunity, Zhao Er asked the armored vehicles to withdraw from the battlefield first.

Before the armored car came to the open space of the research institute, Fan Bufan was already waiting for them here to open the door of time and space.

Fan Bufan let the armored car group enter the gate of time and space first, and then continued to wait there.

When Zhao Er saw the armored vehicle leaving, he let the tank retreat and attack, fighting as he went.

Relying on strong power, even if it reverses, it can drive fast, and the T72 quickly distanced itself from the Sherman of the US military.

Zhao Er took this opportunity to let the helicopter pour all its firepower and slow down the speed of the American armored pursuit force.

When the pursuit of the U.S. troops slowed down, Zhao Er once again ordered all tanks to fire smoke grenades to cover them.

Taking advantage of the smoke, the tanks turned around one after another, then withdrew at full speed, and soon arrived in front of the research institute, and then rushed into the space-time portal without slowing down.

In the end, the Mi-24 fleet also relied on good mobility and flew back.

At this point, all of Fan Bufan's troops were successfully evacuated, and Fan Bufan looked at the American troops in the distance who were deep in the fog, and then walked into the gate of time and space without looking back.

When the U.S. troops arrived, they saw a mess and an empty research institute.
