To be honest, Mu Yun felt very sorry when he saw so many energy crystal clusters.

If all these energy crystal clusters are used, it will be enough to elevate countless apprentices who make constructs to the level of masters, not to mention that energy crystal clusters have many other uses.

But it is precisely because of the many that there is a possibility of detonating and breaking this area.

Mu Yun kept walking underground and recording. The range of the entire energy crystal cluster was very wide, at least much wider than the width of the fortress. There were even some crystal cluster caves that had not been mined by demons. Mu Yun might not have been able to enter if he had not been through his estrangement.

When Mu Yun walked through the soil and saw a void scene appearing in front of him, he realized that he had arrived at the edge of this continent.

Outside is a shiny void, with space cracks flashing from time to time. Looking closely, you can see the existence of this boundary film belonging to this layer of demon abyss. As long as you leave here, you can go back to the outside.

However, whether in the real plane or in the spiritual plane, there are many flickering cracks floating. Mu Yun knew that if he fell into it, he might be teleported to some other place, but more of it might be cut off in half.

With Mu Yun's current strength, he can't tear open such a space and leave, so the scenery in front of him is just a look.

After investigations from both sides, the situation under the entire fortress was finally imprinted in Mu Yun's mind.

The number of crystal clusters can be said to be almost countless, including those that have formed mines and those that are still buried in the soil and have not been excavated. The total number is as many as hundreds.

Apart from those undiscovered crystal clusters, there are more than 30 excavated places left, and the total number of demon excavators in all mines is tens of thousands!

This is a very huge number. Even with so many demons and gray dwarves, the number they can dig is less than one-third of the total. You can imagine how huge the crystal cluster is.

Perhaps because there was no enemy attack for a long time, the supervisors in the mine were not very alert, but this did not relieve Mu Yun because there were too many.

It’s okay to say that those crystal clusters that have not been discovered are just enough to transport the self-destructive insects. And it’s not a problem to put the number of them, and they can have sufficient power to detonate.

Logically speaking, detonating these crystal clusters that add up to more than two-thirds of the total amount is also very likely to detonate this area, but Mu Yun dare not be so careless, because there is only one opportunity, and if you miss it, you will be gone.

So how to put self-destructive insects into these crystal clusters is a difficult problem.

The first way Mu Yun thought of was to let the Zerg Heart develop and improve the claws and teeth of the self-destructing insects to adapt to the nearby soil. Then Mu Yun took them into the soil outside the crystal cluster and ordered them to break in and detonate together.

But this takes time, which will give the mining demons and gray dwarves time to react. If they detonate or destroy the self-destruction insects in advance, it will definitely bring variables to Mu Yun's plan.

The second way to think of was to let these Zergs disguise themselves as stones or soil, and then Mu Yun used his hidden characteristics to put these bombs into it.

This will indeed detonate all self-destructive insects quietly, but no one can guarantee that they will not be discovered during the process of quietly placing the self-destructive insects. Moreover, the time for doing this will be extended for a very long time, which greatly increases the risk!

These are all issues that I had discussed with Ying before, but Ying didn't have time to investigate the situation, so there was no unified opinion at that time. But after watching it, Mu Yun knew that the difficulty was much more difficult than I thought.

Another most important problem is that the number of self-destructing insects can reach the level of self-destructing insects that can detonate the energy crystal clusters cannot be lower than the fifth level. Moreover, in hundreds of places, even if twenty are prepared in each place, all of them will be more than two thousand.

Twenty is not enough for some large mines, so a rough estimate is that at least 5,000 self-explosion insects can meet the requirements!

This number is much larger, and it can only be relied on Mu Yun to transport it. Judging from his soul power, it is completely insufficient. At least it will take several days to do it.

Even if Ying was present, it would be difficult to help him, because at that time, there would be a strong man in the Devil Cube to restrain Ying, and it would be difficult for her to get rid of her body.

The ideal idea is to break through the fortress and occupy all the main roads of the fortress. So at that time, how can you send self-destructive insects in?

But after seeing the number of energy crystal clusters, Mu Yun knew that this idea was difficult to realize. The Devil's Cube would definitely fight to defend the main roads of the mine, and after knowing the coalition's ideas, he would definitely fight to stop it.

Mu Yun even thought maliciously that if the other city lords and generals of the coalition forces knew about it, they might all want to stop Mu Yun and Ying's actions. After all, it is a very good choice for them to bring a batch of energy crystal clusters while being able to go out.

These things can sell a lot of resources on the mainland, and may attract more major forces or families to come here to dig. How could Mu Yun and the others explode in this case? And after the blowdown, they would lose their connection with the exile land. As long as they are not fools, they would never choose to do such things.

Humans are greedy and are not worse than other races at this point, so what Mu Yun can rely on is Ying and himself.

Fortunately, there are still time. Each method has its loopholes and flaws, and has its own advantages. Mu Yun thought about it and felt that it would be a good choice if he could improve it from the self-destruction worm itself.

There will be no shortage of raw materials. The existence of so many demons in the Demon Fortress wall means that there is a continuous stream of raw materials. The only thing he needs to do now is how to improve the self-explosion insects.

There are many choices, which increase offensiveness, increase the power of self-destruction, increase agility, and increase hiding. No matter which point, it is worth Mu Yun's research and combination.

Mu Yun carefully observed the situation inside the mine. The combat power of the demons and gray dwarves there was not very high. If the self-destruction insect was of level 5, then strengthening some attack power could pose a threat to those enemies.

However, the energy of the self-destructing worm is limited. If these things are added, either the body size will increase or the energy in the self-destructing worm will be reduced.

Energy is conserved, one rises and the other falls, and what is tested is Mu Yun's combined ability.

This is a difficult choice, and it may take a lot of time to deduce. If Mu Yun hadn't been from the soul system, just doing this would have a head that would have exploded.

At this moment, a sudden light of inspiration flashed in Mu Yun's mind, and a bold idea emerged.
