Chu Chen and Fei Fei came out of the system, took the mini version of the super battleship, and left the Tianyun base directly.

Although Chu Chen didn't know where there were metal veins near the Tianyun base, with Fei Fei's super little brain, he probed at will, and found that there was a small abandoned iron ore area in a mountain range dozens of miles away from the Tianyun base.

The mini version of the Super Battleship Ball Ball came out of the system space for the first time, and as soon as it appeared, he was very curious about everything, especially the metal, with a look of eagerness, if Fei Fei stopped him, that look of extreme eagerness, Chu Chen did not doubt at all in his heart that this little dot that looked only the size of a palm would eat all the metal in the entire Tianyun Base.

Chu Chen took the stealthy Fei Fei, a small miniature super battleship, and after leaving the Tianyun base, Ling Bo ran all the way, the speed was much faster than that of ordinary cars, and after more than an hour, he arrived in the mountain range where the iron ore area was located.

Under Fei Fei's constant guidance, Chu Chen soon arrived at the edge of a dilapidated mine that had collapsed half of its side.

Chu Chen stopped to check the surrounding situation, then picked up a gray stone from it, weighed it in his hand, and found that this stone was much heavier than ordinary stones, and it might be iron ore.

Now that he had arrived at the place, Chu Chen was about to ask Fei Fei how the mini super battleship ball could eat the unmined and refined iron ore of this entire mountain.

Suddenly, the mini super battleship, seeing the iron ore in Chu Chen's hand, like a pervert seeing a beautiful woman who had stripped naked, flew over impatiently and snatched the stone from Chu Chen's hand.

Then the whole black body continued to squirm, as if melting into liquid, slowly seeping into the inside of the gray stone, and then came out of the gray stone, and changed back to its original form, and the original gray ore seemed to have been bleached, turning white, and the iron component in it completely disappeared, falling to the ground and snapping into a pile of powder.

Then Chu Chen found that the miniature super battleship had suddenly grown a little, and then the mini super battleship ignored Chu Chen and Fei Fei, and flew excitedly in the direction of the mine.

Chu Chen and Fei Fei glanced at each other, and then Fei Fei suddenly understood the question in Chu Chen's heart, and said: "Host, Qiuqiu is very sensitive to metal, his body can change at will, as long as the metal he touches will be devoured by him and become a part of his body. ”

"Hmm."

Chu Chen nodded knowingly when he heard this, and said, "How much iron ore is in the veins here, and how big can it grow after the ball is devoured?" ”

"It's just a small vein here, and most of it has been mined, and there are about seventy or eighty tons of pure iron in it, but after the ball is swallowed, it can probably grow to about seventy or eighty meters, and evolve to the first stage!"

"Doesn't that mean that as long as the ball is devoured by infinite metal, he can grow infinitely bigger? It will soon be able to become a real interstellar super battleship! ”

"Of course not, what you think is too simple, there is a certain law for the growth of any life, as long as the ball swallows metal, it is right that it can continue to evolve and become bigger, but iron is only the lowest metal in the universe, and when the ball evolves to the first stage, the role of iron in his evolution will begin to decrease, and more advanced metals must be provided to enter the second stage of evolution, and every time it evolves, the corresponding amount of metal required will also increase, but it is not as easy as you think!"

Fei Fei explained.

"That is to say, after the ball evolves to the first stage, in order for him to enter the second stage of evolution, he must provide a higher grade metal, and iron ore and metals of the same grade are useless to the ball, does that mean?"

"That's right, iron is only a first-class metal, and gold, silver, and some other precious metals are second-class metals, so if you want to let the ball enter the second stage of evolution, it will cost a lot of money, at least the ten tons of gold that exist in the system space of the host must be far from enough!" Fei Fei nodded.

"Ten tons of gold is not enough, how much gold is needed for the second stage of the evolution of the ball?"

"Huh? At least 100 tons! ”

Fei Fei thought for a moment and said a number that almost didn't stop Chu Chen's heart.

"A hundred tons?! You're going to sell me anyway, where can I find it?! ”

Chu Chen almost didn't shout when he heard this, he emptied the entire warehouse of the Tianyun Base and only collected ten tons of gold, a hundred tons of gold can be converted into fifty million exchange value, and it can be sold for hundreds of billions of dollars on the earth, and so much money can only allow Qiuqiu to complete the second stage of evolution!

Suddenly, Chu Chen felt remorse in his heart, feeling that Qiuqiu was a bottomless pit that burned money, no wonder Fei Fei said before that even if he let Qiuqiu devour the metal of an entire planet, he might not be able to evolve into a real interstellar super battleship, he thought that Fei Fei was joking, but now he is very wrong!

blamed himself for being too greedy after hearing the power of the interstellar super battleship, and he was confused, completely ignoring Fei Fei's warning, and Chu Chen felt extremely regretful in his heart at this moment.

"Hehe, Lord Fei Fei has warned you a long time ago, but it is your own choice to exchange balls, but although the evolution of the ball is very costly, it is not without returns, after the evolution of the ball, it has a certain combat effectiveness, although it is not as good as the real interstellar super battleship, but the ball combat power that evolves to the first stage is equivalent to an aircraft carrier, and the ball combat power that evolves to the second stage is equivalent to the sum of all the aircraft carriers of country M on the earth!"

"And the most important thing is that Qiuqiu is a living metal, unless it is completely broken or the core Yuan Zhu is destroyed, otherwise, Qiuqiu is equivalent to an immortal body, a completely immortal Xiaoqiang!"

"Immortal, this ......"

When Chu Chen heard Fei Fei finish talking about the power of the ball after evolution, the remorse in his heart suddenly disappeared, the power of the first stage is equivalent to an aircraft carrier on the Azure Planet, and the power of the second stage is equivalent to the sum of all the aircraft carriers of country M, so what about the power of the third stage and the fourth stage?

For this problem, Chu Chen couldn't imagine it, but as long as Qiuqiu evolved to the second stage, it would be enough.

The reason why country M can run rampant on the earth is nothing more than relying on two points, the first is money, and the second is advanced weapons and equipment, especially the aircraft carrier fleet, which has 12 ships, which is the most on the earth.

But as long as Chu Chen evolved the ball to the second order, it would be enough to sweep away the aircraft carrier fleet that country M was proud of, and he would be able to kill half of the combat power of country M in one fell swoop.

"A hundred tons of gold in exchange for such an invincible battleship, although the price is a little higher, but it is still worth the money, besides, there is a lot of gold on the Azure Star, if you want to evolve the ball to the second order, although it is troublesome, it is not impossible!"

Thinking about it like this, Chu Chen felt much more comfortable in his heart, and he didn't bother anymore.

"Fei Fei, how long will it take for the ball to devour this mine, I don't think it's too early, although there are no humanoid zombies here, but I have seen a lot of beast zombies along the way, I think it's better to let the ball be devoured quickly, leave early!"

"It won't take long, with the devouring speed of the ball, an hour will be almost the same!"

Fei Fei's words had just been finished.

"Roar!"

Suddenly, there was a strange roar, accompanied by a gust of scarlet wind that made people want to vomit, a terrifying zombie giant snake more than ten meters long came out of nowhere, and at an extremely fast speed, it suddenly bit Chu Chen's body from behind.

"Host, be careful!"

The zombie giant snake that suddenly appeared didn't know what level of zombie it was, and the speed was so fast that even Fei Fei didn't have time to remind Chu Chen.

But when this zombie giant snake scurried behind Chu Chen, Chu Chen instinctively felt the danger, and carried Ling Bo with a slight step under his feet, which was able to avoid the swallowing of the giant snake.

Although he escaped the bite of the zombie giant snake, the terrifying feeling between life and death suddenly made Chu Chen's forehead continue to break out in cold sweat, panting slightly, and staring at the zombie giant snake behind him.

"What level is Fei Fei, this zombie giant snake, when did it appear, and why didn't I find out with my strength?"

"Host, this zombie giant snake is a sixth-order zombie lord, with a combat power of 12,150 points, and snakes are good at hiding their breath and carrying out sneak attacks, not only you, but even my Lord Feifei almost didn't find out!" Fei Fei also looked at the zombie giant snake with a solemn face.

This zombie giant snake that suddenly appeared and sneaked up on him, the length was about twelve or thirteen meters, thicker than the bucket, the pure black snake body was covered with scale armor like iron sheets, under the reflection of brilliance, it exuded a cold light, stretched out a letter from time to time, and a pair of gray eyes each erected a bright green pupil, staring at Chu Chen, exuding a dangerous aura.

"Zombie Lord, the combat power is 12,000!"

Chu Chen was shocked when he heard this, no wonder even he didn't find out how this zombie giant snake appeared, and his strength was much stronger than him.

"Host, beware, the zombie serpent is here again!"

Seeing that his sneak attack did not kill the human in front of him, the zombie giant snake suddenly flashed with a trace of doubt in his eyes, but soon he attacked Chu Chen again.

The thick snake tail of the zombie giant snake, after a pause, once again carried a huge force, a strong wind howled, and swept towards Chu Chen, this giant snake was originally much stronger than the human being, and after evolving into a zombie lord, it became more and more terrifying.

When Chu Chen saw it, he immediately knew that he was invincible, and wisely jumped high to avoid the attack of the zombie giant snake and giant tail.

When the zombie giant snake saw Chu Chen jump into the sky, his pupils suddenly showed a cunning look of successful conspiracy, and the hideous snake head flicked on the ground, like a huge siege crossbow arrow, flying towards Chu Chen like lightning.

At the same time, he opened his terrifying huge mouth, wanting to swallow Chu Chen directly.

"Damn, this zombie giant snake is so cunning, it actually dug a trap for me to jump!"

Seeing this, Chu Chen immediately understood, he fell into the trap designed by the zombie giant snake, and while scolding in his heart, he was also secretly shocked by the wisdom of the zombie giant snake, which was not worse than that of humans.

First, the giant tail swept, forcing Chu Chen to jump up and dodge, and then took advantage of Chu Chen's leap in the air and had nowhere to dodge, he suddenly attacked, although this trap looked simple, but it was extremely perfect and effective, if Chu Chen's means only stopped there, it would really be difficult to escape the mouth of the zombie giant snake.

But of course Chu Chen's means will not be so simple, he still has a system, and there are mecha in the system space!

Although he was about to die in the snake kiss, Chu Chen's eyes did not have the slightest panic, panic, but a trace of ruthlessness flashed, since Chu Chen got the system, he had experienced a lot of various battles, and he had already sharpened his mind as calm as a rock, knowing that the more critical the moment, the more he needed to calm down, once he panicked, not only was it useless, but he might die faster.

The zombie giant snake saw that the human in front of it was about to be swallowed by itself in the next moment, and suddenly its eyes flashed with pride, since the moment Chu Chen entered this mountain range, it had been staring at this human being, and its evolved eyes could completely feel the huge energy contained in the human body in front of him.

This kind of energy is an incomparable temptation for him, devouring the human in front of him and digesting the energy in it, maybe he will be able to evolve into a stronger zombie king giant snake, so in order to sneak attack this human being, it does not hesitate to quietly follow behind this human being, until the time is ripe just now to suddenly attack, but unfortunately it still let the human in front of him realize and escape.

But soon it set a trap to lure the human in front of it into the air, although the human in front of it is not weak, but when it reaches the air, there is nowhere to escape if there is nowhere to borrow strength, as long as it is swallowed into its stomach, with the stomach acid in its body that can melt gold and iron, it only takes a minute or two to digest the human in front of it.

When this zombie giant snake was thinking about it, the corners of Chu Chen's mouth hooked up a sneer!

"If you want to swallow me, it depends on whether you have a good pair of teeth!"

Seeing that he was about to fall into the mouth of the zombie giant snake, Chu Chen directly summoned a brand-new mecha from the system in the air, before returning to the Azure Planet from the earth, Chu Chen exchanged a total of ten mecha from the system, plus the original repaired one was eleven, sold to Bai Baiyun two, destroyed one during the battle against the zombie general, and eight brand new mechas.

Therefore, the moment Chu Chen summoned the mecha, the zombie giant snake immediately cupped, and the two twenty or thirty centimeter-long giant teeth on the palate of the giant snake immediately fell on the mecha's body.

"Click!"

"Click!"

Then there were two extremely crisp sounds, the zombie giant snake that was dreaming beautifully, suddenly felt a sharp pain in his mouth, and then the two extremely sharp giant teeth that had accompanied him for decades were instantly broken by the hard body of the mecha!

"Quack, if you want to swallow me, your teeth will be broken, you deserve it!"

Chu Chen let out an evil laugh at the zombie giant snake, and at the same time, at this time, he opened the protective shield, quickly drilled into the mecha's body, and drove the mecha to the ground steadily.

The zombie giant snake didn't expect that Chu Chen would have this trick at all, and he immediately suffered a big loss, and the severe pain made it let out a weird roar.

"Call! Call you sister! You want to eat me, I haven't settled accounts with you yet, don't think it's great to grow up, and the master will beat you to death! ”

Chu Chen was attacked by this zombie giant snake, and fell into its trap again, almost didn't hang up, and was holding back the evil fire in his belly, the strange roar of the zombie giant snake suddenly made Chu Chen even more unhappy, driving the mecha, waving two steel-armored giant arms and smashing at the zombie giant snake's head.

The dull sound of "bang......" kept sounding.

The zombie giant snake didn't react at first, but then it was smashed a few times by the strange force of the mecha, and it became more and more dizzy and overwhelmed.

However, Chu Chen didn't care whether the zombie giant snake was faint or not, driving the mecha to the zombie giant snake was a violent beating, and he vented the anger in his heart fiercely.

However, Chu Chen was very happy because of the violent beating of the zombie giant snake, and at the same time, he was surprised by the defense of the zombie giant snake, so far he had really never seen such a monster resistant, and the power of the mecha weighed at least nearly a ton per punch, and even a half-meter-thick cement wall could be blasted.

But after bombarding this zombie giant snake for a long time, except for occasionally being able to hit the scale armor on its body, it did not cause too much damage on the zombie giant snake, and the defense of this zombie giant snake was not known to be many times stronger than the zombie general that Chu Chen encountered in the city last time.

After a long beating, the zombie giant snake lord finally woke up from the pain coming from all over his body, and infinite anger flashed in the gray-white pain!

Unexpectedly, it calculated Chu Chen like this, but instead of eating Chu Chen, it was broken with its giant teeth, and was even beaten by the huge steel monster driven by Chu Chen.

Ever since it evolved into a sixth-order zombie lord and became the overlord of this mountain forest, when had it ever suffered such a grievance and this kind of shame?!

Furious, it decided to kill the human in front of it, and with a shame, its huge body flipped over, and its huge tail flicked fiercely, smashing towards the mecha.

Seeing this, Chu Chen refused to show weakness, although his physical strength was not as strong as the zombie giant snake, but the strength of the mecha was not necessarily worse than the zombie giant snake, for the huge tail that roared, Chu Chen drove the mecha to stretch out the two claw-like palms of the mecha, and grabbed it hard, and clamped the tail of the zombie giant snake tightly.

"Hey, hey!"

Seeing the mecha grabbing the tail of the zombie giant snake, Chu Chen suddenly let out two more evil laughs, and then drove the mecha, like a chain ball, grabbed the tail of the zombie giant snake, and spun and shook wildly.

Suddenly, with the mecha as the center, within a radius of ten meters, suddenly a violent wind howled, like a tornado, and a cloud of dust flew up.

After a while, suddenly from the center of the tornado, the zombie giant snake was thrown out by the mecha, flew dozens of meters high, and then landed on the mountain hundreds of meters away, crushing a large area of trees.

But even so, the zombie giant snake still didn't suffer much damage, and quickly got up again and coiled into a ball, just like the immortal Xiao Qiang, two erected straight pupils, emitting a cold light staring at the mecha and Chu Chen in the mecha.

And Chu Chen was stared at by the zombie giant snake and suddenly had another bad feeling, and sure enough, at the moment when Chu Chen had doubts in his heart, the zombie giant snake coiled into a ball, like a spring, flicked on the ground, and actually flew up, towards the mecha and Chu Chen.

"Damn, I can still fly!"

Chu Chen grew his mouth and shouted in surprise, although he knew in his heart that the zombie giant snake was not really able to fly, but only relied on its powerful strength to bounce itself up, but even this was enough to make Chu Chen feel shocked.

After the zombie giant snake catapulted into the air, it swooped straight at the mecha with incomparable precision, and then the huge body directly wrapped around the mecha's body, tightly strangling.

"Suffered!"

The mecha was strangled by the giant snake, Chu Chen suddenly shouted that it was not good, once it was tightened by the zombie giant snake, with the strange power of the zombie giant snake to evolve to the sixth order, I am afraid that the mecha would not last long.

Chu Chen reacted instantly, wanting to throw the zombie giant snake off the mecha's body, but the zombie giant snake was not stupid, and did not give Chu Chen a chance at all, his huge body directly wrapped around the mecha several times, and opened his giant kiss, squirting out a stream of black liquid.

As the black liquid came into contact with the mecha's body, black smoke suddenly rose from the steel body of the "Woo Ya" mecha, and it was melted by the black liquid.

"What kind of liquid is this, it's so powerful, the metal shell of the mecha can melt!" Chu Chen asked in surprise.

"This is the stomach acid of the zombie giant snake, the acidity is thousands of times that of ordinary acid, it can dissolve iron and gold, host, be careful!"

Fei Fei quickly answered Chu Chen's doubts and reminded at the same time.

"Thousands of times more than ordinary acid, don't you want to be so exaggerated, the mecha can't stand it, let me have an electric light cannon, and see if I can hit it into two sections!"

At this time, not only was the steel body of the mecha constantly melted by the stomach acid of the zombie snake, but at the same time, the zombie giant snake continued to retract its body, and the hard body of the mecha seemed to be unable to withstand it, making a 'coo' compression sound.

At the same time, the values of the mecha's body, energy, and defense displayed on the display screen in the mecha are constantly dropping, dropping by twenty or thirty percent all of a sudden, and these data are still falling wildly.

Therefore, Chu Chen was a little anxious in his heart and wanted to turn on the electric light cannon, wanting to blast away the zombie giant snake wrapped around the mecha, but Chu Chen just wanted to press the button of the electric light cannon, but the zombie giant snake spit out more gastric juice, and the various data of the mecha suddenly fell below the 15% cordon.

The energy of the mecha electric light cannon is 100% is 15 percent, and even the electric light cannon can't be turned on this time.

"Host, hurry up and get out of the mecha, this lord-level zombie giant snake is too powerful, and the mecha is not an opponent!"

Fei Fei saw that Chu Chen's situation was not good, and hurriedly suggested to Chu Chen.

Chu Chen also nodded when he heard this, the mecha had been destroyed by the zombie giant snake, and if he didn't leave the mecha, maybe even he in the mecha would be entangled and strangled to death by the zombie giant snake!

Quickly opening the protective shield of the mecha, Chu Chen jumped out of the mecha.

As soon as he came out, the two arms of the mecha were the first to be unable to withstand it, and they were broken by the zombie giant snake, and then the entire body of the mecha was wrapped around the zombie giant snake, and it shrank in a circle, turning into a large piece of scrap metal.

"It's the first time I've seen such a terrifying monster, how can I fight and fight to death, the high defense is terrifying, I think only the electric light cannon of the mecha can kill it!"

Chu Chen looked at the zombie giant snake crawling down from the completely destroyed mecha with a solemn expression, and was about to summon another mecha, when suddenly, the Great Emperor near the entire iron mine began to shake violently.

"Fei Fei, what's going on? Is there an earthquake?! ”

Chu Chen was shaken by this sudden shock, and his body shook for a while, and he almost didn't stand firm.

"It's not an earthquake, it's the host, it's Qiuqiu, Qiuqiu is coming out!" Fei Fei's eyes were fixed on the direction of the mine, and she said happily to Chu Chen.

"Ball Ball?!"

When Chu Chen heard this, his eyes also flashed with joy and expectation, looking at the direction of the mine, he had been entangled with the zombie giant snake for more than half an hour, and the mini super battleship had finally devoured the entire iron ore and was about to come out!
