When David rode his war horse to the castle, Baron Dubois's subordinate knights had already opened the door for him.

The knights were very familiar with David, and soon a knight came in to report, and of course they would not let David wait at the door.

David got off the horse and walked into the castle gate. The horse was picked up by the knights, and he had a dedicated person to take care of the horse.

"David, you're here!" Before David could walk out of the hall, he saw Knight Miller running over happily.

"What's wrong with you?" David couldn't help asking when he saw the appearance of Miller's Knight.

Miller's Knight looked a little miserable. His left hand was fixed, and his posture was a little awkward. It can be seen that his injuries were not healed.

You should know that the healing potion in the Great World of God is very good. It can make Knight Miller look like this. You can imagine how severe the injuries he suffered before.

"Don't mention it, I almost died after being hit by a level 4 Zerg!" Miller Knight said with lingering fear.

David didn't know whether Miller Knight was lucky or unlucky, so he said that he was lucky enough to survive if he met the Level 4 Zerg, which was of course extremely lucky.

If David himself hadn't had so many talented abilities, he would have probably become one of the many soldiers who died in battle.

It is said that Miller Knight is unlucky, he can always encounter the Level 4 Zerg.

"Didn't you follow Uncle Dubois? How could you encounter the Level 4 Zerg?" David asked curiously.

"This..." Miller Knight obviously didn't want to explain, so he changed the subject and said, "Uncle is waiting for you, hurry up!"

David didn't ask much when he saw the appearance of Miller's Knight.

In fact, it was his own responsibility to get injured by Knight Miller. Baron Dubois fought a Level 4 Zerg, seriously injured the Level 4 Zerg, and the Level 4 Zerg turned around and fled.

At this time, the Miller Knight actually felt a hot mind and rushed forward to stop the level 4 Zerg.

The result is of course conceivable, and it was knocked away by a level 4 Zerg.

Fortunately, the Level 4 Zerg thought of escaping at that time and did not attack with all their might, otherwise the Miller Knight would not be able to jump around like this now.

David and Knight Miller came to the hall and saw the butler standing respectfully.

"Butler, I brought some dishes here, and today's lunch will be made with the dishes I brought!" David stopped and said to the Butler.

"Yes, Master David!" the butler bowed and responded.

"What, you brought the dishes? Did you make them yourself?" Miller asked with his eyes shiny.

He still remembers the dishes he ate during the mission, those cooked by David under the conditions of simplicity. Now how delicious are the dishes that David has officially made? Just think about it and you will saliva.

"Master Miller, pay attention to your etiquette!" the butler reminded.

David was a little surprised by the butler's attitude, but the Miller Cavalier immediately restrained his arrogant attitude.

"David, give me the dishes and I'll send them to the kitchen. Otherwise, the taste will change after being exposed for a long time!" Miller said with a serious expression, but his eyes were constantly turning, which made David feel like he wanted to laugh.

"Okay, I'll leave it to you!" David then transferred the dishes to Miller Knight's space ring.

"Uncle is in the study, you go directly to the kitchen first!" Miller Knight swept the dishes in the space ring with his spirit, and couldn't wait to walk towards the kitchen while talking.

The housekeeper bowed to David and hurriedly chased him. He didn't want the dishes to go wrong and lost his dignity in front of David.

David walked into the hall and came to the study with a familiarity.

Baron Dubois was looking at something, looking up at David, smiling and pointing to the chair beside him.

David walked into the study and sat down on the chair, waiting for Baron Dubois to finish the matter.

After waiting for a while, Baron Dubois put down the paper in his hand and walked to David to sit down.

"David, Knight Cade has praised you very much for me. You have played an important role in this battle!" Baron Dubois said to David with a smile.

"It was Cade Knight who saved me. The target of the 'Titan Black Beetle' is me. If it weren't for Cade Knight's move, it would be difficult for me to be safe!" David also expressed his gratitude to Cade Knight.

"It seems that the 'Half-Body Spider Queen' is still very revengeful. You should pay attention to the War Star in the future!" Baron Du Bois also knew about this, and he reminded him.

"Thank you for Uncle Du Bois for your concern, I will!" David nodded, and of course you should be careful when he was targeted by the fifth-level Zerg's "half-body spider queen". Then he said: "I encountered a mantis Zerg on the battlefield with a height of only 1.5 meters. The level is about level 4. Do you know what Zerg it is?"

If David wants to make the "Assassin Mantis" into a puppet, he certainly needs to know the information about the "Assassin Mantis".

This is also one of the main reasons why he came to find Baron Dubois. Only by getting the answer from Baron Dubois. If Baron Dubois didn't know about it, he probably wouldn't be able to understand it elsewhere.

"A mantis level 4 Zerg of 1.5 meters, 'assin mantis'! The 'assin mantis' you encountered?" Baron Dubois whispered softly, then said in shock.

As Baron Dubois, who knows the background of the "Assassin Mantis", after learning that David encountered the "Assassin Mantis", his first thought was that David was still alive now, and he was even more lucky than the Knight Miller.

"Do you know the message of that mantis?" David asked again with joy.

"'Assassin Mantis' is a special level 4 Zerg. Its defense is very weak, but its instantaneous attack power is extremely strong. Some of the top-level "Assassin Mantis" can even threaten the level 5 Zerg. The "Assassin Mantis" are killers trained by the level 5 Zerg, not the Zerg that grew naturally. This is the "Half-body Spider Queen" who wants to kill you!" Baron Du Bois explained in a deep voice.

David was not surprised at all that the "Assassin Mantis" was sent by the "Half-Body Spider Queen".

But I didn't expect that the "Assassin Mantis" did not grow naturally, but a killer specially trained by the fifth-level Zerg.

David immediately thought of his situation. If the "Half-Body Spider Queen" sends such a killer, he will be in great trouble.

If he was not holding the third-level shield with the aura of "half-body spider-back" on the battlefield, he would not have noticed the special nature of the "Assassin Mantis".

As long as the "Assassin Mantis" approaches David and attacks David at the speed of the "Assassin Mantis", David cannot dodge at all.

In fact, David is very similar to the "Assassin Mantis". Both have the ability to hit a fatal blow and also have the ability to hide their breath. However, although the defense of the "Assassin Mantis" is weak, it is the weakest among the level 4 Zergs. It is not like David's defense is still level 3.

"David, you are careful recently and try not to go out alone. If possible, you can leave the War Star for a while. Although the 'Half-body Spider' is revenge, as long as it can't find you for a while, it will not continue to cause trouble for you!" Baron Dubois continued.

"Uncle Dubois, I am a soldier. Everything must be followed by the military's arrangements, but I will be careful!" David said solemnly.

"Actually, I have extra worries. Since you can escape safely from the 'Assassin Mantis', you must be able to escape next time you meet the 'Assassin Mantis'!" Baron Du Bois said with a smile.

"I have another thing to ask Uncle Dubois. I heard that there is a golden krypton crystal. Is that true?" David asked again.

"Where did you hear it?" Baron Dubois looked at David curiously and asked.

"I just heard it accidentally, but I have never seen it before, and I have never mentioned the Chaofan I met, so I was a little curious!" David said embarrassedly.

He didn't want to deceive Baron Dubois, but the core secrets involved in this were so he could only find an excuse.

"This matter is a secret of the top leaders. It doesn't matter if you have your strength to tell you!" Baron Du Bois thought for a while and said, he paused for a moment and continued: "The name of the golden krypton crystal is the perfect krypton crystal. Only the best krypton crystal ore will be produced in a small amount. The energy in the perfect krypton crystal is very important to the strongest and the fifth-level Zerg. Even the most powerful weapon in your federation, its core also needs the perfect krypton crystal to provide energy!"

"I have also discovered Krypton Crystal Ore. The Krypton Crystal Ore has produced a lot of top Krypton Crystal Stones. No perfect Krypton Crystal Stones were found at that time..." David suddenly stopped halfway through his speech.

He thought of the powerful and terrifying "Stone-Skinned Worm" king. He could never imagine that such a Zerg with special abilities and extremely powerful appeared on the ruling planet.

You should know that at that time, fourteen extraordinary people were dispatched but could not do anything to the King of "Stone-Skinned Worm". Many people were killed and injured by the King of "Stone-Skinned Worm".

Now that I heard that there is still a "perfect-level krypton crystal", I can't help but suspect that the "stone-skinned worm" king absorbs the energy from the "perfect-level krypton crystal" and then mutations.

"What happens if the low-level Zerg absorbs the energy from the 'Perfect Krypton crystal'?" David continued to ask.

"This kind of thing rarely happens. The 'perfect krypton crystal' is very precious and is a very important resource for the fifth-level Zerg. If the energy in the 'perfect krypton crystal' is absorbed by the low-level Zerg, it will be broken by the energy almost immediately. There is only an extremely low probability that it will mutate and become a powerful Zerg with special abilities!" Baron Du Bois replied with a smile.

This kind of knowledge is actually very important. This knowledge has been studied by countless people over the past ten thousand years. If he had not been very close to David, he would not have spoken it.

You should know that the research on "perfect-level krypton crystal" is a very high-level research in the Interstellar Federation or the Great World of God. Not to mention ordinary people, even most extraordinary people don't know.

With extraordinary levels, the energy in the "Perfect Krypton Crystal" is too high, and the extraordinary people cannot absorb it at all. The only consequence of forced absorption is death.

Therefore, the Interstellar Federation did not disclose the information of "perfect Krypton crystal" to Chaofan, but regarded "perfect Krypton crystal" as a strategic resource.

"When I was guarding the planet, I encountered a 'Stone-Skinned Worm' king. It is extremely powerful, has the ability to drill the ground, and has strong defense and terrible recovery ability. More than a dozen extraordinary people cannot defeat it. I doubt whether it has absorbed the 'Perfect Krypton crystal'!" David also briefly explained the situation of the 'Stone-Skinned Worm' king.

"It is unlikely that only the war stars can give birth to 'perfect-level krypton crystals'. Unless there is 'pregnancy crystals' in the Krypton crystals in other areas, 'perfect-level krypton crystals' will not appear!" Baron Du Bois shook his head and said.

For the ruling star, the probability of "pregnant crystal" appears is not as good as saying that the ruling star has "perfect level krypton crystal".

So Baron Dubois judged that the "stone-skinned worm" king was an ordinary mutant Zerg, but it was a bit special.

But David believed that the king of the "Stone-Skin Worm" was lucky to absorb the energy of the "Perfect Krypton Crystal", not only survived but also mutated.

Because David obtained the "pregnancy crystal" from the nest of the "Stone-Skin Worm", of course he did not find much, but later the "Stone-Skin Worm" king searched for David almost regardless of life or death for the "Pregnancy crystal".

Even later, the military learned about the appearance of the "pregnant crystal" on the ruling planet, and almost searched the entire ruling planet and dispatched countless warships to search.

Now that I think about it, the real function of "pregnant crystal" is probably not just to accelerate the production speed of Krypton crystal ore, so that Krypton crystal ore will not dry up. The bigger reason is that Krypton crystal ore that produces top Krypton crystal can produce "perfect grade Krypton crystal".

"Uncle Dubois, where can I get the 'perfect krypton crystal'? Is there any krypton crystal in the Zerg occupied area?" David continued.

"David, the 'perfect krypton crystal' has no effect on you. You'd better not try to absorb the energy in it, as it will cause you to explode and die directly. Even the Zerg with strong constitutions cannot bear it, let alone humans.

However, it is not difficult to know where to have the 'perfect Krypton crystal'. Here is a map marked with some krypton crystal mines that produce 'perfect Krypton crystal'. However, there are very dangerous places, with level 4 Zerg defense." Baron Dubois first persuaded David, but he also knew that David was a very independent person and could rely on his own abilities to achieve his current achievements, so he decided to help David.

As for what David wants to do with the 'perfect Krypton crystal', Baron Dubois doesn't want to ask.

The Krypton crystal mine that produces the "perfect grade krypton crystal" was only part of the Zerg occupied area. He naturally would not take it out from the Great World of God and the Interstellar Federation. Not to mention that this is the highest secret, I would just say that it would be possible to steal it if David could not.

The map is made of a special animal skin, which is very tough, with nine krypton crystal mines marked on it, all in an area of ​​500 to 1,000 kilometers inside the Zerg-occupied area.

Baron Dubois chose Krypton crystals in these areas for David's safety. If David enters the Krypton crystal mine, it will be almost impossible for David to come back alive if he enters it.
