The size of the tank is not too large, but it is extremely heavy, roughly estimated to be 200 kg.

Yunlang tried several times, but he only moved slightly, and he couldn't hold it at all.

He scratched his ears and cheeks around the energy storage tank, at a loss.

"Master, do you need Vivien to serve you?" Vivien's strength had already recovered somewhat, and when she saw that her master was in trouble, she hurriedly broke free from the maid's support and walked forward to ask.

"This thing is too heavy...... Wait a minute, let's find more people to carry them away!" Yun Lang replied casually.

Vivian smiled faintly, bent down and grabbed one end of the energy storage tank, and clamped it up with a little force with one arm.

"The weight is acceptable...... Master, how do you place it?" she quickly changed the subject in order to avoid embarrassing her master.

"Ah...... Ah......h

Suddenly, he was also a little embarrassed: "You are really amazing...... If you're not too tired, take it with you and follow me for a while, and you won't be delayed for too long!"

This amount of energy storage tanks is at a normal level for Vivian. It is probably equivalent to a normal person carrying twenty or thirty pounds of things, which is not light, and it is not too heavy.

If she is not in a state of weakness after the madness, or she runs ten kilometers with an energy storage tank, it is not impossible to do it. But even if you are a little weak now, you can still run a kilometer or two with an energy storage tank.

Therefore, she did not hesitate to respond. Then, let the maid who supported her go back to her own business.

"Don't worry, Vivien still has some strength and will never let her master down. She put the energy storage tank on her shoulder, got ready, and asked, "Master, what is the purpose of this magical creation you summoned?"

Yun Lang didn't think about how to explain for a while, so he didn't answer in time.

Vivian saw that her master seemed to be a little embarrassed, and she misunderstood, so she blamed herself: "Master, Vivian shouldn't have asked for your secret, please punish you!"

"Hehe, don't look like you've done something wrong at every turn, and I won't punish you for no reason!" He has gradually adapted to this new identity, and has gradually figured out a more appropriate way to deal with it, and now when talking, he is much calmer than at the beginning.

After a pause, he continued to encourage a few more words: "You are my battle maid, the most important and intimate helper, I should have shared my secret with you. It's just that in Corrant City, things are a bit complicated, and I have to be a little more cautious. ”

"Master, Vivien is lucky to be your battle maid, and she will be proud of it!"

Ever since she became a battle maid, she has always felt that there is an invisible gap between her and her master, and she has always wanted to pass through it, but she can't do anything about it. Something like this is not something that can be easily achieved with the efforts of just one party.

But fortunately, her long-term efforts have not been in vain, and she has finally gained more trust from her master.

The butterfly dance in her hand is a good proof of this......

Yun Lang smiled faintly, and after sorting out the wording, he added to answer her question: "The thing you are carrying is a very important thing, with it, it will continuously produce butterfly dances and kinetic energy bullets...... Well, it's a rodless arrow that you can understand. ”

Out of caution, he still didn't mention the matter of collecting soul energy, so as not to be misunderstood by her.

"Really....... Really?" Vivien couldn't close her mouth in surprise.

According to her understanding, if the thing she was carrying was the key to making butterfly dances and rodless arrows, then it should be something like a "magic transformer".

If so, the magic fluctuations it produced should be extremely noticeable, but why couldn't she feel it?

Yun Lang nodded, and said mysteriously: "After the death of the purple skin goblin, there will be some extremely special things left, which is another key to making butterfly dances and rodless arrows, so I took the risk to come and collect them!"

Vivien understood it completely.

"Master, can't you let Vivien do something like this?" she kept her master in any accidents.

"For the time being....... Not yet!" He didn't say no, and continued: "You can't detect their existence yet, let alone collect and transfer them yet!"

"Oh!" Vivien replied, with some regret.

She thought about it, as long as she kept him every step of the way, there should be no accidents, so she was relieved.

She was also secretly a little happy, that is, she did not have to worry about the day when the rodless arrows would be used up, but she was also a little uneasy, that is, why the master's magic was so different, what he had been collecting for a long time, it would not be dark magic...... Even dark magic should have mana fluctuations.

In the end, she still chose to trust her master and did not dig into it......

Once Vivien understood what her master was going to do, she was able to follow this direction and start to provide more help.

She has a lot of combat experience, and she can pour out a lot of things from the traces left after the battle, plus her eyesight is also relatively good, so she quickly found out the location of the rest of the purple goblin corpses, and took the initiative to guide Yun Lang to it.

After Yun Lang collected two more soul energies, he found the corpse of the last purple-skinned goblin at the edge of the battlefield.

When the two of them arrived, the purple-skinned goblin was not dead, and although it couldn't move, it still stared at them with a pair of triangular eyes, staring at them in horror and resentment, and cooing incessantly.

"Commander, forcibly stripping a living being of its soul energy would violate the Benchmark Code. The Smoke and Rain reminded in time, but it was not forcibly stopped.

Even if the smoke and rain didn't remind him, he couldn't do anything. Because the goblin didn't die, the soul energy wouldn't leave the body, and he couldn't collect it in the first place.

Since the purple goblin hasn't breathed yet, let's help it, okay?

Yun Lang looked around, picked up a lost spear, and gritted his teeth, stabbing at the goblin's broken body.

In the past, he had never even killed fish and chickens, but he was used to it.

Now, in such an environment, he is bound to make some changes, otherwise it will be difficult to survive in this world.

Now is a good opportunity, and of course he wants to give it a try.....

With a "slap", the spear pierced the purple skin, and it bounced off and slipped off.

He didn't give up and tried again...... But it's still the same.

Vivien was a little overwhelmed, and after putting away the butterfly dance, she took the initiative to ask: "Master, the skin of the goblin warrior is very hard, and it is generally difficult to pierce without fighting spirit or magic!

Yunlang was ashamed, and tried again silently.

This time, he deliberately stabbed through the wound of the purple goblin, and he was so angry that he couldn't get into it because he didn't believe it.

With a "poof", he successfully stabbed three or four inches, but it seemed to be on the bone again, and it was difficult to advance an inch.

He wanted to take back his spear and start over. But it seems that something is stuck again, and I can't pull it out at all......

Yun Lang was so angry, he hugged the spear and shook it......

The purple goblin was in great pain, cooing and cooing, as if he was either insulting or begging for mercy.

Yunlang was unmoved, and tried to kill it.

The purple-skinned goblin couldn't stand it anymore, and the cooing stopped abruptly, and turned to a hoarse and low human voice: "No..... No...... So tormented Liz and killed...... Leeds!"

Yun Lang was shocked when he heard this, and subconsciously left the position of the spear and retreated to Vivien's side.

Vivien was slightly stunned, then immediately stood in front of her master and grabbed the spear.

"Don't kill it yet...... Yun Lang hurriedly stopped.
