After changing the oxygen, Gu Yao did not leave in a hurry, but motioned to Zhou Qingyu to take off the oxygen from the frogs. Zhou Qingyu immediately understood that for such a long time, Gu Yao did not wait for rescue, relying on the oxygen on the enemy's body to continue his life!

He was not polite, and immediately made a move, carrying two bottles of oxygen with Gu Yao each, and then swam with him towards the depths of the warehouse.

The darkness of the seabed, no one can imagine, and the lighting equipment on the two of them is fully turned on, which can only illuminate a little place around them.

Fortunately, the warehouse is a warehouse after all, and the space is limited, so the two of them quickly turned around, and among the boxes of materials, the two of them found out what was most likely to be the energy of the space-time machine. It was a black box, written in English and Huaxia, with four big characters written on it. After repeated confirmation, the two decided that this was what they were looking for!

The energy must be transported away in time, Zhou Qingyu and Gu Yao had the same idea, and worked together to lift the box. At this time, the two of them found that the box was so heavy that if it wasn't in the water, it would not be possible to lift it with manpower alone!

Together, the two lifted the box out of the warehouse and swam outside. Zhou Qingyu quickly found the rope left behind, and in order to prevent the box from falling into the trench, he untied the rope and tied it to the top of the box. The attention of the two of them was all on the energy of time and space, and they didn't pay attention at all, and a few people slowly emerged from behind the seaweed, and they were quietly approaching the two.

The people who tried to intercept Zhou Qingyu and Gu Yao were four frogmen who had been lurking for a long time, and judging from the details of the diving suits, they were not the same group as the people in the warehouse.

The cold light in these people's hands was shining, and they all took out daggers, trying to kill people and seize treasures.

Obviously, Gu Yao and Zhou Qingyu didn't turn around, and the two tacitly lifted the box and smashed it behind them. A frogman couldn't dodge and was crushed underneath the box. The other knocked off the weapon in his hand, was grabbed by Gu Yao's head, and slammed it the box, and a thick thing floated upwards with the mist.

The two accomplices were killed at once, and the numerical advantage of the frogs was broken, so they could only continue to attack, and soon died under Gu Yao and Zhou Qingyu.

Gu Yao unveiled the mask of a frogman, and judging from his appearance, the other party should be from R country.

Unable to speak under the water, the two men were silent, carrying the box like coolies, and now nothing was more important than this large, dark box.

Along the rope, they met the people who answered them one after another, and the big guys worked together, and finally worked together to carry the box to the water.

When bathed in the sun again, Gu Yao could barely open his eyes, he looked up at the late autumn sun, and suddenly laughed, he was fine, he left the abyss alive, and he could go back with space-time energy.

This time, from Gu Yao's entry into the water to his return with energy, it took eight hours, not to mention the physical exertion during this period, and the pressure in the deep sea area alone is not something that ordinary people can bear.

Therefore, when Gu Yao returned to the deck of the Penguin, he was greeted by all the soldiers and seamen. In everyone's eyes, General Gu is worthy of being the blade of the country, at this moment he took off his diving mask, and his resolute face was bathed in the sun, just like the legendary god of war!

Gu Yao turned around, bent down, and stretched out his hand towards the suspension ladder, and behind him, he followed Zhou Qingyu closely.

And Zhou Qingyu was stunned for a moment, and then accepted Gu Yao's kindness, he took Gu Yao's hand and took advantage of his strength to go to the deck.
