When Du Fei was struggling with tactics and strategic strength, Yan Dingtian seemed to have guessed Du Fei's mind and took the initiative to come to the door.

"I've added a weapon system to the Sky Eye system, mainly a nuclear strike capability, and you should like it." Yan Dingtian's hologram said expressionlessly.

"Oh?"

"Space-based mobile nuclear bomb depots." Yan Dingtian said.

Yan Dingtian said and demonstrated the operation of the space-based mobile nuclear bomb depot, in fact, to put it bluntly, it was an airship flying at an altitude of 20,000 meters, carrying a nuclear bomb.

This is different from dropping a nuclear bomb on an airplane, because the plane cannot stay in the air for a long time, and it has to take off every time it is used, and then how to get to the target location, which is slower than launching a nuclear missile directly.

The space-based mobile nuclear bomb depot is permanently suspended at an altitude of 20,000 meters, and is equipped with the latest stealth technology, which is difficult to be detected by the evolutionary body in a non-combat hiding state.

The time required to launch a nuclear bomb from a mobile nuclear bomb depot from launch to detonation is no more than 1 minute, which can greatly improve combat efficiency.

Du Fei's aggressive combat method now is to use the power of the nuclear bomb to inflict a devastating blow on the Corrupt Giant Tree, and ensuring that the nuclear bomb can explode in the most appropriate place is the key to dealing with the Corrupt Giant Tree.

Yan Dingqin obviously upgraded the Tianyan system after analyzing Du Fei's combat methods.

Du Fei obtained the control authority of the space-based nuclear bomb depot, and when he was controlling the nuclear bomb depot airship, he suddenly thought of a guess and said: "I guess, you are hiding in such an airship." ”

Du Fei has never given up searching for Yan Dingtian's hiding place, but the Blood Clan agents have been searching for the imperial capital for several months, and they have not gained anything.

"Yes." Yan Dingtian didn't shy away at all, and replied directly, "If you are interested, you can use the Tianyan system to find me, this game is very interesting." ”

"Looks like you're not just hiding from me."

Du Fei said uncertainly.

"I had already left the imperial capital before we first met. It's really not specifically to hide from you, it's just to not be controlled by some people whose selfish desires are greater than everything else. If I want to do what I want to do, I have to disobey some people's orders. Yan Dingtian replied.

"You're a simple person, but it's hard to understand." Du Fei was moved.

"That's because you're too complicated."

In the space-based mobile nuclear bomb arsenal, there are not only three yield hydrogen bombs, but also three nuclear storm bombs.

That's right, Nukastorm is a crystalline ignition weapon, which can also be called a superwave destruction device.

At present, the research on crystallization ignition technology is still in progress, but Yan Dingtian himself can make a nuclear storm bomb.

It's just that the nuclear storm bomb that one person can make is limited, and if you want to mass produce it, you need to popularize technology, and Yan Dingtian can make it, but other laboratories and thermal weapons manufacturing plants can't make it.

At the end of the conversation, Du Fei made a decision, putting the Entering Dirt level first, and strengthening himself at present is the biggest improvement in combat power.

So he had the luxury of classifying the old unit Pandora Crystal into the evolution consumption, preparing to break through the level 5 barrier at the fastest speed.

At home, Yaya scooped up a rice ball from the big bowl with a spoon and put it into Eliya's bowl, and said, "Sister is a ......" and then put another one in her own bowl and said, "Yaya is a ......"

"A sister, a girl...... It's time to start. After the little devil divided it, he scooped one up and put it in his mouth with great interest, puffed out his cheeks and chewed it a few times before swallowing it, and then said, "It's delicious, sister, eat it quickly." ”

Du Fei returned home at this time, lay down in front of the table, and was immediately attacked by the fierce gaze of the little demon king.

"I'm going to eat it too." Du Fei said with a child's heart. …,

Illya immediately scooped one with a porcelain spoon and handed it to Du Fei, Du Fei opened his mouth to eat, but the girl jumped up angrily and shouted, "Don't eat!" ”

Du Fei quickly ate the rice balls, licked his lips, and looked at the little demon king with a smile.

"Bad guys, bad guys, bad guys......" The little devil jumped wildly.

"You little villain, you don't have a small temper, but your evolution is too slow. Didn't you say you were going to protect your sister? That's not going to work. Du Fei subdued the little demon king with one hand.

Du Fei just wanted to tease her when he said this, but the result was a little speechless.

There are many ways and means for the apocalyptic awakened to evolve, and there are also many cases of inexplicable evolution.

Du Fei originally didn't insist that these two little girls must evolve strongly, but now it's very good, and when used as an auxiliary ability, the effect is good.

However, the next morning, when the little devil was very resentful of Du Fei, he sneezed, and then a vision occurred in the surrounding environment.

The positions of various furniture bottles and cans have been chaotic and displaced, and the furnishings in the house are instantly messy.

Well, one sneeze evolves.

Du Fei looked at the messy room and the little demon king who was yawning while rubbing his eyes, and there was nothing left but black lines on his head.

It should be said that the evolution of the little demon king is a good thing.

However, the little devil will be very happy, and he will go crazy and make his head big.

Du Fei also wanted to sneeze and enter the U-level, but obviously not everyone's opportunity is so legendary. Compared with the secret level of level 5 spatial movement ability, the gap is very large, and now the little devil can get the villa away, which means that if she is not stopped, she will take the house to the wild camping for two days, and then move back.

Fortunately, Ilia is in charge, otherwise the buildings in the base city will be demolished by her.

After the little demon king evolved to level 5, Du Fei took out the spatial barrier generator he had obtained from the Freemasons.

This set of spatial barrier generators was originally prepared by the Freemasons to deal with Du Fei, but the Freemasons' operation was unsuccessful, and this set of spatial barrier generators was in Du Fei's hands.

Du Fei handed the space barrier generator to Yaya and tried to let her activate it to see if she could use it.

The result was a pleasant surprise, with the help of Illya, the little devil was able to start the machine.

The two little girls can use this set of space barrier generators hand in hand to create a cube-shaped space barrier.

This barrier can trap even a level 5 self, and its effect feels strong.

The limitation is that it needs to be used by a Level 5 Spatial Awakener, which leads to a greatly reduced value of this set of Spatial Barrier Generators.

However, the Dark Twins are indeed talented, and the two little girls can actually activate this set of machines with the tacit cooperation of the source ability.

With this set of spatial barrier generators, there is one more means when dealing with some powerful individuals, and the role it can play in team battles is undoubted.

Du Fei handed over this machine to the little devil, but this little girl didn't like this machine because it didn't explode, it wasn't violent enough, and it wasn't exciting at all.)
