Although the nuclear explosion mayfly sounds very powerful, but this is only a high level, there is still a level of room to improve, since you still have an abundant metal crystal, then simply be willful once, and directly promote the death sandworm and the mechanical kun beast to the ultimate. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After the two hundred metal crystals were consumed, the mechanical kun beast and the death sandworm were successfully promoted to the ultimate, and the prompt sound sounded in my mind again.

"Due to the upgrade of the mechanical Kunbeast to the ultimate, the body length has increased to 1,000 meters, and the nuclear explosion mayfly has been upgraded to a polyexplosive mayfly, and the number has increased by 100 million, opening the ultimate ability to infinitely gather and explode."

"As the mechanical death sandworm has been upgraded to the ultimate, its body length has increased to 1,000 meters, and the death devouring ability has evolved to the ultimate, opening the ultimate ability devouring differentiation."

Hearing these two prompts, especially the ultimate ability in the back, Yang Ming snapped his fingers excitedly, this is what he wants, these two names are very awesome when they hear them.

However, Yang Ming was a little curious about what this Gathering Explosion Mayfly was, it was even more powerful than the Nuclear Explosion Mayfly, appearing on the body of the Ultimate Mechanical Kun Beast, and the ultimate ability seemed to have something to do with this Gathering Explosion Mayfly.

Yang Ming focused on the Gathering Explosion Mayfly but did not get more detailed hints, if he wanted to know what was going on with this Gathering Explosion Mayfly, he could only wait until the Zack Clan came to test it on them.

There is also the devouring differentiation of the dead sandworm, which seems to be the ability of the splitting class, which can only be tested at that time.

In less than a minute, 222 metal crystals were gone, Yang Ming felt a little cold sweat at the moment, damn it, I always felt that it was not enough when I had hundreds of metal ability values before, and then I still felt that it was not enough to have millions of metal ability values, and now I have tens of billions, and it is still not enough.

Yang Ming rubbed his somewhat swollen head, now that the mechanical Kun Beast and the Death Sand Worm have been promoted to the ultimate, it is this 24-hour production time that is really uncomfortable to wait, I don't know if there is an option that can reduce the manufacturing time.

This base status bar is a bit more complicated than that of the metal heart, Yang Ming looked for it, and found the option of rapid manufacturing in the sub-menu mechanical life of the technology column.

Rapid Forge (Mechanical Life): Increasing the level of Rapid Fabrication can speed up the construction time of Mechanical Life, currently level 0, each level is reduced by 10% on the basis of the first 24 hours, and Level 10 Rapid Forge can instantly create any mechanical life, and each level increase requires the consumption of 50 Metal Crystals.

After reading it, Yang Ming calculated that it would take 500 metal crystals to quickly upgrade this mechanical life to level ten, and he could afford it now, so it was better to directly upgrade it to level ten once and for all.

Thinking of this, Yang Ming raised the rapid manufacturing option of mechanical life by one level, and a prompt sound came out of his mind.

"Rapid Fabrication (Mechanical Life) is currently Level 1, and the current mechanical life build time is 21.6 hours."

In this way, each upgrade can shorten the manufacturing time by 2.4 hours, and don't underestimate these two hours, every additional mechanical Kun Beast or Death Sandworm built will likely be a key factor in turning the tide of battle.

Yang Ming did not hesitate to upgrade the rapid manufacturing to the second level, and the construction time was shortened to 19.2 hours, which saved more than 4 hours, and the effect was still obvious.

Yang Ming then upgraded and upgraded it to level three, shortening the construction time to 16.8 hours, but when Yang Ming wanted to upgrade to level four, a prompt suddenly sounded in his mind.

"Can't be upgraded, needs an intermediate base."

Hearing this prompt, Yang Ming's face showed such a look, he knew that he would definitely not let himself upgrade safely, and another intermediate base appeared.

How should this primary base be upgraded to an intermediate base, there doesn't seem to be an explanation in the metal heart status column, Yang Ming thought for a while and tried to shout: "Upgrade the base to intermediate." ”

"The number of primary bases is less than a thousand, and it cannot be upgraded."

Yang Ming was a little confused when he heard this, a thousand primary bases can be upgraded to the intermediate level, which means that he has to build bases on at least a thousand planets.

Thinking about it, Yang Ming's head is big, and this is just the upgrade of the primary base to the intermediate base, the ghost knows how many planets it is necessary to build a base to upgrade the advanced and ultimate base, isn't this mandatory to let himself invade other planets on a large scale.

Yang Ming was a little skeptical that after he reached the conditions for upgrading the base, he would become the public enemy of the entire galaxy, just like the Zack Zerg?

Yang Ming's body shuddered when he thought of this, but even if he became the public enemy of the whole people, Yang Ming had to do it, because Yang Ming had already seen that the development of this base in the later stage was the key.

Since there is no way to upgrade Yang Ming, he has to give up, after having a level 3 rapid manufacturing (mechanical life), the time consumed to build a giant mechanical life has been reduced by 7.2 hours, which has saved Yang Ming a lot of time.

Since this mechanical life can be manufactured quickly, I don't know if the mechanical power mecha can be made, Yang Ming found the mechanical power mecha column of the technology option in the base, and sure enough, he also found an option for rapid manufacturing (mechanical power mecha) in it, which is also level ten, but it may be because the mechanical power mecha is much smaller than the mechanical life, and only ten metal crystals are needed for each level of promotion.

After Yang Ming upgraded the rapid manufacturing (mechanical power mecha) to level 3, the original manufacturing time of 12 hours was shortened to 8.4 hours, so that a base could build almost 3 planes per day, and produce one more aircraft per day than before.

Now he has a total of four bases, which are the main base of the earth, the three sub-bases of the moon, Venus and Mercury, and the four bases can make 13 of each of the three mecha for Yang Ming every day.

Although the manufacturing time was accelerated, Yang Ming still felt that it was too little, and a dozen mechanical power mecha a day could not solve the problem at all.

The main reason is that the number of your own bases is too small, if you have a hundred bases, then the mechanical power mecha that can be built in a day is close to a thousand, if you have a thousand bases, then the mechanical power mecha built in a day is 10,000, and the more bases you have, then it also means that the faster you can send troops, which is somewhat similar to those development games.

It seems that after the Canglong returns, it is still necessary for him to visit the other planets in the solar system before the Zac clan comes. (To be continued.) )
