"Be careful, Qiuqiu! And Xiaoxi, remember to protect yourself first. "Xiao Xi and Qiuqiu now have greater autonomy, but they are no longer invincible as before, Mu Feng can't let them get hurt, so I reminded them first.

"Got it, Dad!" Of course, Xiaoxi knew how sad Mu Feng and her sisters would be if she was hurt, so she would definitely protect herself. Of course, the premise is that he will conscientiously complete his mission, add blood to Mu Feng, and use the divine protection to protect Mu Feng's safety at the critical moment.

"Alarm, alarm, the refinery area has been destroyed, go into defense mode, remove all the intruders!" The alarm on the wall flashed red, and the cacophony made people's ears hurt.

Mu Feng shook his head and summoned two powerful weapons, and at the same time, he did not spare his demon value, and directly opened the demon value explosion skill, so many legendary bosses still have some pressure, and they must do their best!

At the same time, Xiao Xi was also performing his duties well, sprinkling gorgeous green light on Mu Feng's body, and continued to restore vitality for Mu Feng. In reality, this skill blessed by nature seems to have the function of rejuvenating vitality in addition to restoring life.

Mu Feng was very confident, and he directly faced the legendary alchemy puppet at the front. Now he is in the strongest state, and it would be too much to say if he coaxed him.

"Boom! ~"If anyone sees this scene, they will be shocked. Obviously, Mu Feng is so small compared to the legendary boss in front of him. This is a huge alchemy puppet made of special metal, and when he competed with Mu Feng for strength, he actually lost!

The huge body of the alchemy puppet was attacked by Mu Feng's huge force and fell backwards, which also caused the legendary bosses around him to be unlucky. Suddenly, a little people turned on their backs.

Taking advantage of this mess, the smart ball had already flown up and began to use its own firepower to open the way for Mu Feng.

It's a pity that all the legendary bosses it encounters now are powerful, and the attack power of the ball is obviously not enough. The missile (bomb) explosion could not even leave obvious scars on the metal bodies of these alchemy puppets.

Mu Feng had to sigh, it was indeed a relic of the original powerful civilization of the Skyrim Continent, and it was still much ahead of the engineering developed by just inheriting the fur. If Qiuqiu can be improved by alchemy technology, I believe it will definitely become more powerful, right?

"Come on!" Qiuqiu is at most a support, and Mu Feng still has to solve it himself, Mu Feng waved the two artifacts in his hand, launched an attack again, and rushed into the alchemy puppet group.

Only the artifact in Mu Feng's hand can cause such damage, and every time the sword is cut down, it can cut huge scars. But even if it is in and out, Mu Feng relies on speed, and it will take dozens of seconds to make a legendary-level alchemy puppet incapacitated. It's enough to see how powerful these alchemy puppets really are.

Mu Feng tried his best to make them incapacitated with less damage, so that they could be brought back and see if they could be repaired. It can definitely improve the strength of the coalition forces. It would be nice if we could do it thoroughly.

Maybe CC will like these, you must know that her biological mechanism qì human body is already perfect, but it is the crystallization of the earth's science and technology, if you can join the alchemy technology, maybe you can be more like a real person, and the strength will be much stronger. In terms of combat, any one of these alchemy puppets can fight dozens of CCs.

The final victor was still Mu Feng, who successfully packed these legendary-level alchemy puppets into the space package. Then, as usual, the workbenches were removed.

Last time, I only brought back one or two, after all, time is limited. This time it's much easier, don't leave one, I believe that with these, the alchemy puppet manufacturing speed of the coalition army can be more than doubled, right?

After hitting the third floor, Mu Feng didn't stop and continued to walk up, but he directly saw something that was missed. It turns out that the last time I fought here against Professor Goo, the machine and man combination that Professor Goo Gu piloted is still here.

Once everyone and Professor Goo Gu fought here, and this strange machine piloted by the other party caused them a lot of trouble. But now...... This machine was directly taken away by Mu Feng.

The Demon Legion really gave up this place completely after evacuating, and this time there was no second Professor Gugu waiting for Mu Feng, and some dust had already fallen on the empty control platform.

"How do you get this...... "Although Mu Feng is a master of engineering, it's just a number in the game, and he can't handle these things in the real world.

However, Qiuqiu stood up at this time, only to see that its hands, which had become the muzzle of the cannon, had become normal manipulators again, and then operated on the control platform. After a while, a light lit up on the control platform, and all the monitor-like devices lit up, which could actually monitor the situation of the entire mobile fortress!

"You can, Qiuqiu." I didn't expect Qiuqiu to have such a ability, Mu Feng had to praise Qiuqiu. Even Xiao Xi flew to Qiuqiu's head and gently touched its metal head with her little hand as if in praise of it.

"Master, it seems that I can drive this mobile fortress away." Unexpectedly, Qiuqiu's words almost scared Mu Feng. You can even drive this mobile castle away!

"Really?" Having said that, this mobile castle seems to have been a mobile fortress in the first place, and it can fly freely.

"Yes, master. But it's locked underneath, and the chains have to be severed. Qiuqiu said to Mu Feng. Mu Feng then remembered that before he came in, he did see a lot of metal chains wrapped around this huge moving castle, just so that it wouldn't float around by itself.

"Okay." Mu Feng nodded, and immediately turned into a streamer and flew out. After about a minute, he flew back, and all those chains had been cut off by Mu Feng. I'm afraid that except for Mu Feng, only Crimson has such a speed.

Sure enough, after Mu Feng came back, the ball was manipulated, and the moving castle obviously began to move after shaking for a while.

"It's really nice to come out empty-handed, and to be able to drive such a big guy back. Modify this place, and then it'll be our mobile headquarters. When the war is over, we must find a way to get it to the earth......" This flying fortress made Mu Feng very satisfied, and he had already designed how to use it in his mind.

The speed of the Flying Fortress is neither fast nor slow, but it is also close to catching up with the average flying mount.

Anyway, he didn't need Mu Feng to control it, he simply didn't care, he found a place to sit down, teased Xiaoxi, and quietly waited for the flying fortress to fly to the end. During this period, Qiuqiu asked for help several times, because a passing flying demon launched an attack on the flying fortress, and Qiuqiu couldn't fight because he wanted to control the movement of the flying fortress, so he needed Mu Feng to settle down.

In this way, it took several days to finally drive this huge guy to the vicinity of the coalition barracks. Such a big guy was naturally discovered by reconnaissance planes and satellites a long time ago, and the coalition forces almost thought it was some offensive of the demon legion and wanted to launch a missile to intercept it.

Mu Feng also remembered that he had to notify the other side, and used the communication tool he carried with him to contact the other side, so that he didn't really eat the guide (bullet). Otherwise, the flying fortress that Zhou Zhang finally spent so much to get back would have disappeared directly, and at that time, Mu Feng really cried and had no place to reason, and the people were obviously loyal to their duties and shot down unknown objects.

When they knew that Mu Feng was back, the girls immediately came out to greet them and took the lead in logging in to this mobile flying fortress.

"Isn't this the fortress we did before?" Before they even reached the fort, the strange flying structure was recognized by the girls.

"Great, now it's ours. We have a command that can fly and move! "Mu Feng and Qin Shuang were in contact before, so she knew what this flying fortress Mu Feng would be used for.

"A command that can fly?" The girls were all excited, the situation of the coalition army was difficult before, even if everyone was a high-ranking member of the coalition army, the accommodation conditions were not particularly good. Now it's different, now that you have this flying fortress, you can spend more effort to tidy it up, and then each of the girls can have their own room in this fortress!

In this way, wherever the battle goes, this flying fortress will fly everywhere, and you can always have a good environment to rest. This is what the girls wanted, and they didn't have to live in a marching tent every time they moved.

For the transformation of the mobile castle, of course, it was handed over to the girls. And Mu Feng has more important things to do, of course, to share this harvest with his allies.

The research data of the alchemy puppet was very comprehensive this time, and the entire flying castle was moved. Except for the castle itself, Mu Feng didn't want anything else, so he let all the researchers of the coalition army move away. In this way, the empty castle is also better transformed.
