The four Rilun vine trees were planted by Li Feng, and they seemed to be activated, and they grew in the wind.

A few minutes later, four vine-covered vines were standing in the highest center of the slope.

However, Li Feng's action was obviously not finished, and after planting the four Rilun vine trees, he took out their ancestors, the Rilun Tree Vines.

This big tree was planted by Li Feng, and it grew to a height of tens of meters, and the diameter of the tree was hundreds of meters, covering a shade of a hundred meters in a radius of 100 meters.

Of course, the hundreds of old vines of the Rilun Tree Vine are not to be seen, these five guys, that is Li Feng's last line of defense, they guard the square inch of the blood crystal plant, to ensure that the blood crystal teleportation will not be attacked.

Li Feng only left a small Rilun vine tree seed on his body for emergencies.

The subordinates saw that the boss was moving frequently, and every time something new appeared, their eyes were bulging.

But this is nothing, because the more exaggerated thing is behind, I saw a burst of red light in the blood crystal space, and a terrifying behemoth as thick as a house and with a red flesh color suddenly came out of the space.

Its appearance frightened everyone, what kind of monster is this? It's scary!

"At the foot of the high slope, go." With a wave of Li Feng's hand, the behemoth moved its huge and thick body, climbed down the high slope, reached the plain below, and then burrowed into the ground.

Only a large hole with a diameter of nine meters remained.

It was so terrifying that many members of the external control armed forces woke up to the fact that this behemoth had been summoned by their boss.

This terrifying monster is not a foreign object, it is the mother worm of the prehistoric giant earthworm.

Of course, it was only one-eighth the size of the prehistoric giant earthworm, and the blood crystal space was only nineteen meters in diameter. Theoretically, it cannot accommodate this 70-meter-long giant earthworm.

However, the giant earthworm has soft body characteristics, so it is tired and shrunk, but it is still teleported.

It can be seen that in order to stabilize this camp, Li Feng can be said to have spared no expense and took out some trump cards.

A prehistoric earthworm is clearly not enough. It didn't take long for him to start teleporting the second and third again......

A quarter of an hour later, there were a total of eight split prehistoric giant earthworms, of which seven were teleported by Li Feng, leaving only one to stay in the shelter to guard.

As long as she doesn't die, even if the seven prehistoric giant earthworms teleported over are dead, the mother worm can still go to Tongguò to eat. Regrow her body of more than 300 meters.

Of course, this process requires a lot of food resources, but Li Feng has a heaven-level purple fungus life stock, and he can afford it.

As soon as the matter was completed, after Li Feng sent a large number of forces and fortification personnel over, the entire small loess high slope entered the defense project in a race against time.

A large amount of cement was brought over. With everyone working together, the slope of the high slope is being buried. Only by plugging the cement will it not be easy to be attacked by the monster hordes that are good at digging.

In addition to this, the construction of the city walls on the high slopes began.

A large number of machine guns, artillery battlements, and towers have all been planned and designed, and the slope work will be completed immediately.

With sufficient manpower and resource supply, these projects can be regarded as major projects. However, the estimated time given by the chief engineer will take one month to complete, which is due to Li Feng's investment of a lot of human resources.

During this period, Li Feng did not stop at all. A week later, he had received the second shipment of arms and ammunition from the polar bears.

And the steamroller and the scorpion also contacted the black market arms dealers over there, and smashed them with money, buying a lot of powerful explosives and artillery.

One of the most powerful artillery pieces is the self-propelled rocket artillery vehicle.

This kind of rocket car, with a total of 16 rockets loaded at a time, can be regarded as the most powerful weapon like a semi-missile.

Li Feng spent a lot of money to get two cars, and then directly passed them over and arranged them.

In addition, a large number of howitzers, mortars, cannons, anti-aircraft guns, coastal artillery were also transported.

Among them, the coastal artillery is the heavyweight of many artillery, which is usually erected in the sea-based and directly hits the ship's conventional heavy artillery weapons, and the representative of land-based weapons, Li Feng got a total of four from the polar bear.

The Nighthawk helicopter was also brought over, all armed, and even installed with aviation cannons.

Suddenly, this loess plateau, which was not too large, was armed by Li Feng into a fortress of war.

As for the insect soldiers, Li Feng also teleported here, the seventh-order demon ant soldiers, the fifth-order Amazon giant bird-eating spider, and the fifth-order Galapagos giant centipede, these three types of troops were each teleported to three thousand numbers.

Except for the Demon Ant Soldiers, who have combat instincts, the latter two are large-sized Battle Bug Soldiers.

The Amazon giant bird-eating spider is capable of forming cobwebs and is good at holding on, and the Galapagos giant centipede is capable of spewing poison from a distance.

At the same time, 10,000 Titan Crypt Ants were turned around by Li Feng the next day, and any of them was to dig up this loess high slope mountain.

Li Feng not only wanted to occupy the ground area of the high slope, but also to create a huge space within the slope, in order to serve as a strategic base.

The space that was about to be dug up, under the deliberation of a group of core elders, it was decided to build a large ammunition processing factory inside.

The main thing is to process and produce rifles, machine guns, machine guns, and other ammunition that requires a lot of consumption.

At the same time, some small shells of rocket artillery, mortars, and howitzers will also be produced and processed in the mountains.

Of course, this is a relatively long-term preparation plan, before that, Li Feng has to get these ammunition production lines and technicians in hand, and he also needs to develop nearby resource mines and develop resources.

I have to say that the resources of this world are too rich, and its richness is far more than the number of biological species, but also mineral resources.

Maybe it has never been explored by humans, or maybe the world itself is older than the earth, so there are too many minerals hidden in its ground, which have been explored by explorers.

In just a few miles around the camp, they discovered iron ore one after another. Lv ore, tin ore and other common resources.

Time passed with the haste to build the fortifications, and by the twenty-seventh day the fortifications of the camp, though not yet complete, showed their fierce defensive force.

The dam has been completely blocked with cement, and the slope is slightly smoother. Under the deliberate artificiality of the engineering team, all of them were made steep.

The protective wall was also completed earlier than expected.

From a distance, the view is that a solid castle rises on a slope of about 100 meters.

The walls were 15 meters high and 25 meters wide.

The wide walls can not only house a large number of defense troops, but also tanks, coastal guns and many other artillery pieces can be erected on them.

And due to the absolute high momentum, these guns had a longer firing range. A large number of machine-gun buttresses, as well as tall reconnaissance towers, alert towers, fire towers, and anti-aircraft towers, were all built in various positions on the high slopes, and there were basically no dead ends.

Besides.

The hillside is also divided into two areas, the first is the outer control area, and the innermost is the core area.

The core area is the second line of defense. The second line of defense was erected with a large number of strong iron mesh, and the wire was thick and tough. It's definitely not the kind of ordinary material barbed wire that you usually see.

And all of them are electrified, forming a second line of defense for the grid.

All of them showed good signs.

As for the past twenty days, it is not that there have been no monster groups attacking Gao Po, but because of Gao Po at this time, they have long been armed to the teeth.

A large number of artillery and machine guns directly repelled them.

There are two kinds of monsters that are coming. One of them, already quite familiar, is precisely the Cunning Beast race.

This group of monsters was obviously here for revenge, and it was unknown where they had brought in a larger group of Cunning Beast monsters, gathering a group of thousands of kindred. then launched an assault on the camp.

However, it is a pity that Li Feng has cemented all the slopes because he has witnessed these monsters who are good at digging, so it is difficult for them to realize their idea of digging holes and sneaking up to attack.

Without this kind of surprise attack, a thousand cunning beasts, under the fierce firepower arranged by humans, would only deliver food to the insect soldiers.

And the second kind of attacking monster made Li Feng and the others more concerned, this should be a group of monsters nearby, they have long pointed beaks, hold spears, human-like bodies, and are covered with black scales.

The speed of action is very fast and the number is large, this is a race of monsters between the second and fifth orders.

The weakest ones are only two orders of strength, and the strongest one is the fifth order, who has just stepped into the warrior level, and the information that Li Feng obtained from them is called the Black Scale Man.

Yes, the name is the Black Scale Man.

It turned out to be called a human, and it is estimated that it is a humanoid creature, and its specialty is explosive strengthening.

This explosive enhancement ability is a bit quite ferocious, that is, in an instant, this kind of black-scaled person can stimulate potential.

The speed of his bloodline talent exploded to three times, and the speed was extremely fast, if Li Feng's city walls were not built, it was estimated that even if they could be killed, the external control members would probably have a lot of casualties.

The territory of these black-scaled people is just more than ten miles away from the north, and they can be regarded as neighbors, and there are quite a few of them.

More than 3,000 black-scaled people were dispatched when the attack came.

After these days of investigation and reconnaissance, Li Feng has also figured out the geographical location and actual situation of the loess high slope.

The location of the high slope is very wonderful, and it is precisely the border vacuum between the one-legged bull monster and the black-scaled people.

Therefore, Li Feng has made such a big move in Gaopo these days, but there are still very few monster races to attack, which is precisely why.

Although there are a large number of these black-scaled people, they can't bring much of a threat, Li Feng just paid attention, but he didn't pay too much attention to it, as long as they guarded the camp, these black-scaled people were not afraid to break through the camp fortress that was now more and more fully defended.

Therefore, near the end of his fortifications, he already had the intention of returning.

At the same time, he finally had a hint of ambition, and Li Feng once again set his eyes on the neighboring one-legged bull monsters, and what he looked at was the thick skin on their bodies. (To be continued......)
