The artificial sand pile covering an area of ​​one square kilometer is not only the material entrance and exit of the institute, but also a permanent fortification.

At the top of the sand pile is a command room with a very good view and can overlook the overall situation outside.

Li Qingyu and Mark stood side by side in front of a lookout, watching a large transport plane flying towards them in the sky.

"If there were no ordinary passengers in the plane, I could get all the enemies with just one nuclear warhead! Now, in order to save the lives of those ordinary people, my hundreds of soldiers have to risk their death to fight with each other. Sometimes, I don't know if this choice is wrong or not? Is it too stupid! The life of the warrior is also life!" Mark said with a little desolate look at the plane flying towards them.

They actually have a lot of helplessness.

"I don't know if your choice is correct, but I know that your choice is absolutely not stupid. If I encounter such a thing, I will definitely make the same choice as you." Li Qingyu said in a relaxed tone.

Before the war, you should relax.

While the two were talking, the transport plane reached the sky above the big sand pile. The rear cabin door of the plane opened, and a figure jumped down from the sky. It seemed that a human-shaped rain was falling!

"Fire! Stop them and shoot them, don't let them enter our inner circle of defense!"

Once these people enter the inner circle of defense, they will definitely not be able to defend the entrance of the fortifications!

With Mark's order, the gunner who had been on standby immediately fired the fire, and shot straight into the sky with one shell, flying towards the enemy that was landing rapidly in the air!

These shells are made of cold crystals. The shells are not bullets. Even if a small-success warrior in the Xuan Realm is hit, they will be frozen instantly and temporarily lose their ability to move!

You should know that these enemies are brave and brave. When they jumped from the plane with their own realm, they did not use a parachute at all, but jumped down like this!

When they can freely exert their strength, there will naturally be no problem, but if they are hit by a cold crystal shell, they become an ice sculpture, lose their subjective initiative, and fall to the ground, they may be finished immediately!

If the Qisha Hall’s Transformation Master is hit, there is no possibility of survival!

Therefore, after a group of guys still in the air realized the danger, they immediately did not dare to jump from directly above the institute, but adjusted their figures and landed from a distance.

For ordinary people, it is natural to be difficult to adjust their landing direction if they have nowhere to leverage their power in the air. However, for experts above the realm of transformation, this is just a pediatrician.

Their figures are as clever as butterflies in the air. They can not only adjust the direction of descending freely, but also change the speed of landing by constantly shooting strong winds!

But what makes them depressed is that although they can avoid shells, they cannot avoid the local instantaneous cooling caused by the explosion of the cold crystal!

A large number of cold crystal shells exploded around them, causing the temperature around them to drop rapidly, almost instantly to minus one hundred degrees Celsius! Even though they are all masters, such a low temperature makes them feel uncomfortable, as if the blood in their bodies is about to solidify.

In this way, they were even more afraid to land directly above the institute, and just wanted to land a little further.

As long as they land on the ground, they don’t have to be afraid of each other’s cold crystal shells!

The people of the Galaxy Fleet dared to lower the temperature in the air to below 100 degrees Celsius, but did not dare to lower the ground temperature to this level. Otherwise, the combat effectiveness of the Galaxy Fleet would be greatly affected!

When Mark saw the other party flying obliquely into the distance in the air, he immediately ordered loudly: "Search and shoot! Before they land, shoot all the cold crystal shells for me! How much their realm can be suppressed by us depends on our round of artillery bombs! But, fight me and hit me hard! It is best to knock them all out of the air! Who can defeat an enemy, I will give him a first-class merit!"

Under heavy rewards, there must be a brave man!

Those ordinary members of the Galaxy Fleet were originally unable to participate in the subsequent hand-to-hand combat because of their poor strength, so they vented all their ruthlessness on the guns and cannons in their hands. Not only were they bullets like meteors, continuous, but everyone also performed their best shooting level!

The people from the Hidden Family are not bad, but they can avoid shells with high realm and strong strength. However, the group of people from Qisha Hall were a little distressed. The warriors who were peeping the gate in the realm became slow due to the influence of temperature. They were a little embarrassed at this moment. Some people who could not dodge were hit and instantly frozen into ice, falling to the ground, and falling into pieces!

"Okay, you're good at it! Fight me! Keep hitting hard!" Mark seemed to be drinking too much, his face flushed and he ordered loudly in excitement.

Li Qingyu was also shocked when he looked at the corpse that kept falling from the air.

Although the cold crystal is not as useful as the spiritual crystal, and after being made into ammunition, it is not as powerful as the spiritual crystal bullet, but the earth produces cold crystals!

Although mining is difficult and the output is low, it is produced after all!

The US Galaxy Fleet can use cold crystals to make shells, can the Chinese Galaxy Fleet use spiritual crystals to make shells?

No! You can't even let it go!

"Grandma, when you have the opportunity, you must go to the Hanjing Mine controlled by the United States to see. It would be a big loss for China to not interfere with this thing!" Li Qingyu couldn't help but think in his heart.

Just as Li Qingyu was thinking, the sound of gunfire in his ears became sparse, their ammunition was exhausted, and at this time the enemies had almost all landed on the ground.

When the enemy landed on the ground, it did not fall to the same place, but surrounded the entire research center.

The enemy originally had 300 people, but after the reduction of the number of troops just now, there are only more than 240 people left.

A sand pile covering an area of ​​one square kilometer was surrounded by more than 240 people, with only more than 60 people in each direction. The encirclement must be very sparse, but this did not affect the other party's confidence in taking the institute!

More than 240 people seemed to be shooting at the large pile of sand in the middle!

A master of the hidden family was galloping forward quickly, and a long sword suddenly pierced from the desert under his feet and rushed straight to his lower abdomen!

The long sword appeared very suddenly without warning!

However, the masters of the Hidden Family were not panicked at all. They just waved it out and a golden shield appeared in their hands. Not only did they block the sudden knife, but the strong wind was also storming, blowing up the sand layer in front of them, revealing an immortal warrior hiding under the sand layer.

The shield suddenly slashed down, and the immortal warrior who was two meters and four meters tall, had a steel and iron bones, his head was blooming, and red and white things splashed everywhere!

The brief collision between the two people kicked off the battle, and all the undead soldiers who were originally hidden in the sand launched a raid on the enemy!
Chapter completed!
