After everything was completed, Ye Fan made a pre-war general mobilization for all the members of the Dragon Group, and handed over the temporary command to the leopard.

The leopard has already become the new leader of the dragon group, and the command is handed back to the leopard, which is normal on the surface.

"Head, this operation, without you personally in command, I ......," the leopard said with a frown.

Ye Fan waved his hand and said, "How to attack and how to retreat, I have already arranged it." Don't you even have the ability and courage to carry it out?"

"No, I ......," the leopard said hurriedly.

Ye Fan interrupted the leopard again: "This battle is very important and very arduous. Not only do you have to fight for your life, but I am no exception. I have to step out of the circle and no longer act with everyone to open up another battlefield and grab a glimmer of hope for our dragons. ”

"Head, you mean ......" the leopard was taken aback.

Ye Fan interrupted the leopard's speculation again and said, "I can't tell you for the time being." ”

"Yes, head. The leopard took a deep breath and his gaze became more respectful.

Ye Fan and the Bulong Group acted together, and the leopard would not suspect that Ye Fan had escaped at all. In the past few years, as the leader of the Dragon Group, Ye Fan has not taken the lead? He has absolute trust in Ye Fan.

After handing over the command to the leopard, Ye Fan quietly left the dragon group and infiltrated the Kumogo grassland.

Taking advantage of the night, Ye Fan opened the large package he had taken with him, took out a set of combat clothes from it and changed it on, put on a helmet, and then held a gun.

After Ye Fan dressed up like a soldier in the Kumogo Underground Biochemical Research Base, he held a machine gun weighing more than ten catties in his right hand and a 50-kilogram handbag in his left hand, and then sneaked near the entrance of the Kumogo Underground Biochemical Research Base unknowingly.

Kumogo's underground biochemical research base is heavily guarded, and there are no dead ends at the entrance, under normal circumstances, no matter how high Ye Fan's skills are, he can't sneak in.

However, Ye Fan's current goal is not to sneak in for the time being, but to infiltrate the force alert range at the entrance of Kumogo's underground biochemical research base, and then hide and wait for the opportunity.

Two days later, with a burst of cannons, the dragon group finally launched an attack on the Kumogo underground biochemical research base.

Kumogo's underground biochemical research base also seemed to vaguely sense that someone was about to attack, so almost at the same time, countless soldiers poured out from inside, and ten thousand cannons were launched to fight back against the dragon group.

At the same time, the two helicopter gunships quickly rose into the air, ready to reconnoiter and strike from the air.

However, the dragon group had been prepared for a long time, and in less than a minute, the two helicopter gunships were shot down by anti-aircraft guns.

The dragon group attacked fiercely, and almost carpet-bombarded the surface of the Kumogo underground biochemical research base from all directions with artillery, and for a time the Kumogo underground biochemical research base suffered heavy casualties.

In the face of such a fierce attack by the dragon group, Kumogo's underground biochemical research base did not fight hard, and immediately contracted its forces.

Kumogo's underground biochemical research base is extremely fortified, and as long as the turtle is cowered near the entrance, it is almost impossible to attack. Moreover, they do have foreign aid. As long as you hold on to reinforcements, it is equivalent to victory.

When the troops sent out retreated towards the entrance in a panic, Ye Fan, who was lurking nearby, also took the opportunity to move, mixed into it, and kept running towards the entrance of the underground foundation.

In the temporary command post, the leopard followed the steps of Ye Fan before leaving, and constantly urged the members of the dragon group to use all their ammunition to attack the Kumogo underground biochemical research base.

"Oh no! Three bomber planes are flying at the same time in the direction of 34 degrees south-east toward our troops! Two bombers are also flying toward our troops in the direction of 21 degrees north-west! Fifteen minutes later, they will arrive over our troops!"

Suddenly, an alarm sounded on the intercom.

The leopard's whole body suddenly tightened, and he hurriedly connected to the contact information of the two air defense missiles that had been signed in advance, and shouted loudly: "Quickly stop Lao Tzu, be sure to intercept it!"

Without waiting for the other party to respond, the leopard immediately switched to another contact signal, took two deep breaths, and then said in a serious and calm tone: "Attention units, in fifteen minutes, enemy bombers will arrive over our troops. After thirteen minutes, if there is no notice, immediately organize the unit to enter the state of air defense!"

At the same time, the faces of everyone in the temporary command post changed drastically.

Even though they have been through a hundred battles and have been on the edge of life and death for many years, no one can calm down at this moment.

The enemy's reinforcements came too quickly, expecting almost two hours, but they arrived in half an hour. Moreover, the enemy actually sent five bombers at the same time.

Once it really gets caught in the front and back, the dragon group will not escape the fate of the entire army.

Six or seven minutes later, information came from the radar monitoring channel that an enemy bomber had broken through the air defense and was flying over quickly.

"Units, please note that one of the enemy's bombers broke through our missile air defense and is flying towards us, and in five minutes, it will enter the state of air defense!" the leopard ordered heavily.

There are not many people in the dragon group, and a single bomber can cause heavy casualties in the dragon group. Fortunately, the dragon group is also equipped with professional weapons to fight bombers.

As soon as the leopard gave the order, the radar monitoring channel again sent information that two more groups of bombers flew from the two directions just now, and the number was as high as seven.

Hearing this, the leopard was stupid.

M|D, is there a U.S. president hiding in Kumogo's underground biochemical research base? Twelve bombers rushed to support.

In the temporary command post, Mo Shu was the first to come back to his senses and said to the leopard: "Brother Leopard, retreat." With our strength, we will never be able to defeat the underground biochemical research base of Kumogo. ”

The leopard came back to his senses and immediately issued an order: "Attention to all units, immediately retreat, all heavy equipment will be abandoned! Attention all units, immediately retreat, all heavy equipment will be abandoned!"

How to retreat, have a plan in advance of departure.

At this moment, suddenly the mountain shook like an earthquake, and a rolling sound came from afar, shaking people's eardrums.

The leopard and the others held on to the table in time to avoid falling.

"Are the enemy bombers already here?" thought to the leopard, "No, bomber bombing alone won't have such power!"

The leopard hurriedly picked up the binoculars and looked in the direction from which the sound came, and was immediately frightened.

I saw that the surface of the underground biochemical research base of Kumogo that they were going to attack had all collapsed, covering an area of more than 3,000 meters, stirring up dust and flying rocks that covered the sky and the sun.

"This ......," exclaimed the leopard subconsciously, "it was the head!"

Everyone in the temporary command post turned their heads to look at the leopard, and the leopard suddenly remembered the specific task issued by his superiors: to seize all the information of the Kumogo underground biochemical research base and bring it back to China, and then to destroy the Kumogo underground biochemical research base.

His eyelids jumped, and he hurriedly denied it: "I'm just guessing, there is no such link in the battle plan! Besides, how could the first person bring so many explosives into it and blow up the entire underground foundation?!"

Mo Shu and the others nodded silently.
