It's a pity that he doesn't know where Ruan Bing's destination is, so he can't chase it out, and can only wait for Ruan Bing to return.

"Brother Lu Jun, do you want me to go out and see for you?" Xiaowan could feel Lu Jun's anxiety.

"No, you go to finish what I said, I'll wait for her to come back here." Lu Jun shook his head.

"Okay, I'm leaving, Brother Lu Jun." Xiaowan nodded obediently, and opened the third form and left the area.

As a result, the road army was left alone, and he did not choose to wait, turning on the dragon form and flying to the southeast side of the West Wind Fortress.

Because there is a place to expand the dragon's nest, after more than a day of accelerated construction, dozens of dragon nests in his system have been completed, and now is the time to place it.

A few minutes later, the road army arrived at the densest area of ​​the dragon's nest, with thousands of dinosaurs resting or moving below.

From a distance, it is very spectacular, like a giant dinosaur paradise.

Looking at this scene, the Lu Jun took a deep breath, thinking to himself that in a week, there would definitely be dozens of times more dinosaurs here.

Immediately after, he let the dinosaurs outside make room for the prepared dragon nest.

Since the model of each dragon's nest is very large, this area looks a little insufficient, and the road army can only continue to place the dragon's nest around the West Wind Fortress.

It wasn't until nearly half of the West Wind Fortress was surrounded and nearly twenty dragon nests were consumed that the Lu Army stopped.

Now he can no longer continue to place the Dragon Nest in the Westerly Fortress, because the Westerly Fortress requires a lot of strategic buildings and space.

He plans to place the remaining dragon nests in other gathering places, such as Tianhai City or Oli City. Those places must also be garrisoned by dinosaurs.

After finishing the Dragon Nest, the Lu Army spent nearly two hours putting the dragon eggs in the armed module.

He didn't let the dragon eggs hatch randomly, but selected them to determine the proportions so that the dinosaurs could cooperate.

For example, how many pachycephalosaurus needs to be matched with a thousand ankylosaurus to achieve the best effect, these are all particular and not careless.

The last thing the Lu Army fiddled with was the genetic modification device. After spending a lot of dragon coins, the Lu Army installed a genetic modification device on each dragon nest and upgraded some dragon nests and devices.

The upgraded Dragon Nest can not only transform D-tier dinosaurs, but also C-tier dinosaurs.

For example, after ankylosaurus was transformed, it became a heavy ice dragon and heavy fire dragon.

From the attribute point of view, their defense power has increased more than twice, with ice or fire elements attached to the carapace.

The characteristic of ice armor is high defensive power, can slow down the enemy's attack and even freeze the enemy, suitable for fixed-point defense.

The characteristic of fire armor is strong attack power, scorching surrounding targets, suitable for charging or destroying target buildings.

From these points alone, we can feel that the genetic modification has greatly improved the ankylosaurus, and they now have the strength of S-tier creatures.

As for why Ankylosaurus had two genetic modification models, Lu Jun was not very clear.

In other words, he is still in the groping stage of genetic modification devices at this time, and he still doesn't understand many functions inside.

Another type of modified is Triceratops, this dragon species was also obtained by the Lu Army some time ago, and it works well with Pachycephalosaurus.

The genetically modified name is Thunderhorn. In addition to maintaining its original size and characteristics, it also has an additional ability to use lightning elements to attack.

It is the three sharp corners of its head that can unite to emit lightning, with an attack range of 30 meters.

Although the effect is not known yet, it is virtually equivalent to increasing the long-range attack capability of the Route Army.

If he had known that the triceratops would have a long-range attack after being advanced, the Lu Jun might not buy those expensive Dilophosaurus eggs, and he still feels distressed about it now.

However, now that he has bought it, the Lu Army will not regret it. A few million Dragon Coins are acceptable to him, and it is estimated that he will be able to earn back a few waves of large-scale battles.

With the addition of two genetically modified dinosaurs, the power in the hands of the Lu Army has definitely become stronger.

As long as he completes the transformation of the Triceratops and Ankylosaurus that he possesses, it is equivalent to adding a group of creatures with rank S strength, and the help to him in the future is immeasurable.

But soon he encountered a new problem, that is, it takes a lot of dragon coins to transform every dinosaur.

Especially the modified C-tier dinosaur is nearly twice as expensive as the D-tier dinosaur, which is very scary.

Lu Jun calculated a little, if all the C-tier and D-tier dinosaurs were to be transformed, it would not work without 10 million dragon coins.

If he wants to continue to transform Tier B dinosaurs, then he has to upgrade the Dragon Nest and genetic modification modules, which will cost tens of millions of Dragon Coins.

It is no exaggeration to say that from the end of the world to the present, the Lu Army has not obtained 10 million Dragon Coins.

In the short term in the future, he actually needs 20 million Dragon Coins to support consumption, which makes him feel very headache.

At the same time, Lu Jun is also thinking about ways to quickly earn Dragon Coins in his brain. It seems that he is going to use any means to get Dragon Coins recently.

However, this is not a simple matter. The current Dragon Coin is equivalent to the currency before the end of the world. It is not something you can get. It is too difficult to get rich overnight, you still have to accumulate slowly.

In desperation, the Lu Army could only choose to transform some of the dinosaurs first, and let the other part of the dinosaurs continue to maintain their normal form.

As for upgrading the Dragon Nest and the genetic modification device again, he can't even think about it now. After all, even if he upgrades, he can't maintain the huge modification fee...

After the dragon’s nest and genetic modification module had been fiddled with, the Lu Army took out the spar of various steps along the road and placed it on the ground. There was a pile almost 50 meters away.

This is for the newly hatched dinosaurs to advance, currently only spar can make them complete the advancement.

Although it is not safe to put so many precious spars on the ground, it is easy to be stolen by people or other creatures.

But here is the Westerly Fortress, the core area of ​​the Lu Army forces. Nearly 100,000 troops are stationed. The surrounding area is in a safe zone, and there is no human or biological energy close.

Moreover, there are a large number of dinosaurs and members of the Resistance Army patrolling around, so the Lu Army is not worried at all.

As for why not take out the spar after fusion, it is because the Lu Army really does not have so much time now.

There are six or seven million spars in the weapon module, and even if he fully integrates, it will take several days.

He is almost busy with himself now, it is impossible to spare so much time anyway, he can only let the dinosaurs eat the unfused spar...
