Zuo Si swam with all his might, and the oxygen consumed in this case was very much, and the air pressure of the diving air tank could not support it for long.

He came to the vicinity of the box, and instead of opening the box directly, he first found another diving gas tank, so that the time under the water could be extended.

Returning to the side of the box, I wanted to pull it out of the mud directly, but I wasted a lot of strength for a long time without success.

I don't know what the box is made of, and it hasn't rotted after soaking in water for so long, and the contents should be worth a lot of money.

Zuo Si dug all the nearby mud aside, and when he dug about ten centimeters, an iron lock appeared in front of the box.

The lock was rusty, long and flattened, and with a slight tug of Zuo Si, it broke on the spot.

Before the box was completely dug out, Zuo Si couldn't wait to open the box.

The first thing you see is a layer of oiled paper, which is used to repel water and keep out the air.

The underneath is full of neat things.

With a stir, he peeled off all the oiled paper.

Eye! My eyes!

A pair of titanium alloy dog eyes were almost blinded.

The box was full of gold bars!

Zuo Si picked up a piece in disbelief and looked at it, it was indeed a gold bar.

He didn't get excited for long, the most important thing now was not the gold, but what the female ghost's sojourn was.

There are so many gold bars here, who knows which one is the sojourn of the female ghost, and even if you know which one it is, the gold is so hard, it can't be destroyed.

"Could it be this box?"

Zuo Si looked at the box, this box looked like mahogany, but he couldn't be sure, it didn't rot for so many years, and it should be worth a lot.

Zuo thought about it, instead of carrying a box of gold, it would be better to only take this empty box, regardless of whether the female ghost's sojourn was gold or a box.

An empty box would be a distraction.

As long as she can't devote herself to the fight, then she will definitely lose.

Zuo Si threw aside all the gold in the box, and estimated that it would be at least more than twenty catties.

Then he took the box and began to swim back.

At this time, Zuo Si found that the oxygen in the diving gas tank was exhausted, so he immediately changed to another one, and looked at the water pressure, which could still support it for about ten minutes.

"I have done everything I can, and if I still fail, then I can only blame my life."

Swimming back to the battle area, Zuo Si raised the wooden box in his hand and waved it, quickly attracting the attention of the female ghost.

The female ghost became extremely irritable when she landed, and the soul body of the fight was injured and rushed to Zuo Si.

Zuo Si was not in a hurry, he already held the scalpel in his hand, and thought: "The female ghost didn't know that I could hurt her, when I attacked her at the beginning, the reason why she dodged should be an instinctive reaction, I have to seize this opportunity and seriously injure her with one blow." ”

It doesn't matter if Ling Yun can hear it or not.

Zuo Si spit out his breath and bit his mouth, shouting, "Restrain her!" ”

Then he threw the wooden box in his hand upward, and the wooden box quickly floated upwards with the inertia and the buoyancy of the water.

The female ghost was about to chase after her, but she was entangled by the drowning boy who followed closely.

Ling Yun and Ye Yingjie followed, hugging the two arms of the female ghost respectively, and did not let go no matter how the female ghost struggled.

At this time, Zuo Si also drifted upstream, regardless of whether it was elegant or not, and whether it was indecent or not.

Hold the scalpel directly and run it through from the bottom to the top.

Yin Qi slanted out.

"Ah!!h The female ghost's terrible roar almost exhausted all the yin power, shook away all the ghosts around her, and desperately wanted to pull Zuosi to hell.

Even if the female ghost has become the end of the strong crossbow, her speed is not comparable to Zuo Si.

There is no way to avoid it, there is no way to hide, so you can only choose to hold on to the scalpel and fight hard.

At this moment, a white figure appeared in front of Zuo Si.

She is pure and immaculate, like a hibiscus out of water, without a trace of dust.

It was Gu Yiyi, at this time, she was closing her eyes tightly, trembling with fright, but she was still standing in front of Zuo Si and did not retreat for half a minute.

The female ghost's attacks all fell on her soul.

Gu Yiyi's soul body immediately weakened a little.

Fortunately, the drowning boy rushed over in time, pulled the female ghost's hair with one hand, and cut off the female ghost's head with a knife with the other hand.

In a few clicks, the female ghost was torn to shreds.

The drowning boy gave him a blank look and then disappeared.

"Hey!" Zuo Siwei stopped him, but as soon as he opened his mouth, he was filled with water and hurriedly spit it out.

Hurriedly bit his mouth again and stuffed it into his mouth.

"Hey! I'm still going to ask him for help with the next mission, why is he leaving......"

Zuo Si sighed secretly and swam towards the shore, Ling Yun and Ye Yingjie consciously returned to their backpacks.

Returning to the high platform in the center of the lake, Zuo Si inflated the diving tank and said, "Gu Yiyi! You come out for me! ”

Gu Yiyi did not respond.

Seeing that she didn't come out, Zuo Si's tone became a little heavier: "I told you to come out!" Did you hear that!! ”

A white shadow flashed, and Gu Yiyi appeared aggrievedly in front of Zuo Si, looking like she was about to cry.

Seeing her like this, Zuo Si couldn't help but feel distressed, and originally wanted to reprimand two sentences, but he couldn't be tough, so he could only say kindly: "Yiyi, didn't I tell you not to come out casually, why are you disobedient." ”

Gu Yiyi said aggrievedly: "I, I'm not afraid that you will be in danger, big brother." ”

Zuo Si was distressed again, naturally knowing that Gu Yiyi wanted to protect herself, but why didn't Zuo Si want to protect her.

"Yiyi, you don't want to be like this in the future, if something happens to you, I will blame myself for the rest of my life, you don't know how to fight, it's useless to come out."

"I knew that I was useless, I couldn't help my big brother......" Gu Yiyi's appearance of being both aggrieved and self-reproachful was too pitiful.

Zuo Si hurriedly comforted: "Who said that Yiyi is useless, Yiyi has helped me the most!" ”

"Big brother...... You don't have to comfort me. ”

Zuo Si took two steps forward, symbolically touched Gu Yiyi's little head, and said: "Apart from you, who can purify the Evil Yin Ghost Gu, you are the most unique existence in this world, if it weren't for you, I don't know how many times I would have died." ”

"Really?" Gu Yiyi's big watery eyes looked at Zuo Si in a blink.

"Of course, you must protect yourself, because your existence is far more important than mine."

"Don't." Gu Yiyi immediately shook her head: "Anyway, I don't want my big brother to have an accident." ”

Hearing this, Zuo Si was very moved in his heart, but for Gu Yiyi's safety, he still said sternly: "I know what I do, and you are not allowed to interfere casually in the future, do you hear it!" Otherwise...... Otherwise, I'll expel you and never take you with me again. ”

"Don't, don't!" Gu Yiyi lowered her head and said aggrievedly: "Won't I be obedient in the future......"

Zuo Si touched her head again and said, "This is my good sister." ”
