However, before Fang Shi and others returned to the west, Xu Liquan reported another bad news.

"Master Fang, the American ships are heading towards your location. If we meet with you, it will be easily discovered."

Fang Shi was stunned. He didn't go to trouble him and rushed over. He simply destroyed the two ships after he started to fire. However, in this way, the Americans must take the opportunity to do a lot of activities here. Although it was Ouyang Houtian and the government who did this, Fang Shi turned his eyes and gave up this somewhat attractive choice.

As for the American ships coming to this side, they must have not discovered the submarine or even themselves. Now there is heavy fog on the sea that interferes with electronic equipment. Under the sea, the barrier formed by the array has become a forbidden area for sonar. Both themselves and the submarine are moving near the barrier. No matter how advanced the equipment of the American people is, they are unlikely to discover it. They should have planned to circle the fog area and just chose this direction.

"You guys go around with them and ignore us. We are just about to enter the formation."

"But Master Fang, if we leave a little distance, we will lose contact with you, and... your oxygen is only enough for an hour, otherwise we will withdraw first."

Oxygen? Fang Shi only remembered that he seemed to have ignored the problem of oxygen. In less than an hour, can he enter Yingzhou Cave Heaven smoothly? If not, can he only float to the sea? I guess the most sophisticated satellite in the United States is staring here at this time.

This question is indeed a bit of scratching my head. Fang Shi looked at the oxygen cylinder behind Ouyang Houtian. It would be great if he could transfer the air into the oxygen cylinder. I don’t know if the Five Ghosts can do it. But it’s very efficient to do this. If it’s only one of you, it’s better to let it go for three people.

Seeing Fang Shi looking at him, Ouyang Houtian thought Fang Shi was asking for his opinion. Of course, he opposed returning to the submarine now. Such a good opportunity was missed. It is estimated that he might not be able to find a way to open the Yingzhou Cave Heaven in his life, so he shook his head firmly and expressed his disagreement to return to the submarine.

Fang Shi thought for a while and replied, "As I said, we don't have enough oxygen, we go to the sea to ventilate. The meeting place is made with the reservation meeting point on the west side. In order to prevent the Americans from discovering the equipment we are left underwater, we must also go in and turn off all the equipment."

The submarine was silent for a long time before Xia Yuyao's voice came: "Then... be careful."

Fang Shi knew that this short sentence contained the concerns and support of Xia Yuyao and even Xia Yuxin for him, and felt warm in his heart and quickly replied: "Don't worry, I won't take risks blindly, have the images been sent back?"

"It's been sent back, we are comparing. It should be a change in the Xuanwu Formation, but we can't determine whether it is the Xuanwu Said Formation."

"It doesn't matter. You can see it when the next change appears."

"Well...if it doesn't work, it doesn't matter if the Americans know."

Xia Yuyao said something as a pretext for public service. Fang Shi understood Xia Yuyao's hint, meaning that he would be the first choice when he had no choice but to save himself as his first choice. As for what would happen, he didn't have to consider.

"I understand, don't worry, you guys leave first, we will turn off the communication equipment temporarily."

"Okay, we'll wait for you."

Xia Yuyao no longer dragged on the mud, so she simply left a pun to turn off the communication equipment. Fang Shi pointed to the communication terminal on his arm, and Ouyang Houtianhe and He Yuanqing both thoughtfully closed the communication terminal. As a result, they had completely lost contact with the submarine.

The communicator suddenly became quiet, as if the whole world had become quiet. The three of them looked at each other, and they even felt a bit strange that they were abandoned by the world.

Fang Shi took the lead to swim towards the barrier. This time they were very close to the barrier and finally felt the velocity of the water flow nearby changed slightly, but this change was not very obvious. Because the distance was closer to a few meters, Ouyang Houtian and He Yuanqing finally saw clearly what was like the mirror. They were so surprised that they almost vomited the respirator in their mouths.

This situation was so strange that even Fang Shi was shocked at that time, let alone these two people who could not intuitively observe the yin and yang breath. After a while, they woke up from the shock and began to find a theoretical basis for the fact in front of them.

Soon, several people heard a noise from the machine from the sea water. It was estimated that the two American ships drove over. Just so happened that the barrier formed by the formation also began to change. The originally uniform blue color of the barrier began to differentiate, and some places became deeper and lighter. This change lasted for about ten minutes, and the barrier became a complex group of lines. These lines were formed by rapid flowing water flow, with a diameter of about one or two meters thick, with white colors, and interlaced flow without interference. It was a wonder.

From a distance, the barrier is still a barrier, but you can see it at close range. There are many gaps in the large net woven by these lines that can be passed through.

However, these gaps of only a few meters in size were constantly moving. Ouyang Houtian and He Yuanqing couldn't help but feel a little nervous when they thought of going through these gaps in a while. Although these gaps did not move quickly, they were still very nervous for no reason out of awe of the strange water flows.

Seeing that the large net formed by the formation stabilized, Fang Shi waved his hand and swam forward. Time is very tight now, so he should hurry up.

Fang Shi calculated the time and speed, and just got into a mesh accurately. After passing through the barrier, Fang Shi felt it. It seemed that the yin and yang aura was stronger here, and there was nothing wrong with that. So he waved to the other two people. Ouyang Houtian and He Yuanqing came in one after another with fear. He Yuanqing's calculation was somewhat deviation when he came in, and he was almost swept by the water flow, which made him so scared that he sweated coldly.

After passing through the barrier, Ouyang Houtian felt much more relaxed and looked around excitedly, but the range of lights was very limited and he could not see anything special. As for the changes in the yin and yang breath, he could only roughly feel that the breath became thicker.

Ouyang Houtian looked at Fang Shi, who waved his hand and signaled them to follow him.

Through two days of observation and the deduction when the formation changed just now, the most important thing is the starlight exposed in the middle of the formation. In fact, it is not a luminous body, but a natural phenomenon caused by the mutual induction of the formation and the stars. Although the first satellite picture is not very clear, Fangshi can still roughly tell that it is the Xuanwu Star Game.

After confirming the big formation, Fang Shi only needs to deduce based on the observed situation and the data collected by the Disha Gate before. These data may be nothing in the eyes of others, but in Fang Shi's eyes, they can be sorted into the eight-point formation data in the general environment.

No matter how smart the formation is, you cannot get rid of the foundation of the eight gate formation. As long as you master this, what is left is to investigate the possibility of changes and find out the rules to derive the conclusion. What's more, after confirming that it is the Xuanwu Star Bureau, the scope of thinking has been reduced a lot.

After the evolution of the formation just now, Fang Shi can confirm that this is the Xuanwu Shadow Front. The Xuanwu Shadow Front is a change in the Xuanwu Star Bureau. The Xuanwu Star Bureau belongs to water. It is of course used here to double the effectiveness. The Tibetan Front Bureau is a kind of reversed situation. The so-called star bureau reversed situation is the reverse direction of the way the formation bureau operates.

The normal Xuanwu Star Bureau collects the surrounding aura to form a pattern of converging qi and gathering wind, and then uses these collected auras for your own use according to the arrangement of the nodes of the array.

The reverse direction has a divergent nature and is generally used as a biochemical bureau, but the Tibetan front bureau is an alternative. The Tibetan wind bureau uses the collected aura as a shielding layer, similar to the isolation array, but it is not as strongly repulsive as the isolation array, but it has a strong physical damage effect, so it is called the Tibetan front bureau, which means hidden sharpness.

However, the pattern of the Tibetan Wind Traffic in front of me is too large. Although the barrier formed is huge, the gaps in it are large enough to make people easily get in. Fang Shi was very clear that this shows that the Tibetan Wind Traffic itself is not for defensive purposes, but has other functions, and the Tibetan Wind Traffic usually does not start at all.

Fang Shi found a transponder fixed on the reef, pressed it a few times, and soon all the transponders and sensing equipment stopped operating. Although the launch distance of these devices was very short, it was more comfortable to shut down in case of precautions. Then Fang Shi came to the place where he discovered the undersea pits and waited quietly.

There was no communication underwater, and the communicator was turned off again. Although Ouyang Houtian was full of questions, he could not ask. He had to wait in his heart and wait for the answer to appear.

Fang Shi looked very calm, but in fact he felt a little anxious. He saw that the oxygen in the oxygen tank was about to be exhausted, but the time node had not arrived for a long time. He subconsciously and frequently looked at the timer on his wrist. There were still a few minutes before midnight, and time passed so slowly.

Finally, the hour hand jumped gently into the middle, as if a switch was turned on, and suddenly the dark bottom of the sea lit up. Ouyang Houtian and He Yuanqing were shocked and subconsciously wanted to retreat, but Fang Shi did not move. The two of them straightened their bodies again with shame and looked at the glowing place.

What shines is a place on the reef plate. Fang Shi had explored this reef plate before and confirmed that there was nothing strange inside the reef plate. But now the facts tell Fang Shi that he was confused and there was a group of magic weapons hidden in the place he had explored.

Fang Shi was also surprised that before these magic weapons were activated, they had no yin and yang aura, and they did not even react to the penetration of the yin and yang aura. They had never seen such magic weapons. The Yingzhou Cave Heaven was indeed extraordinary. Before they entered the door, they had learned a lot of things. Even if they couldn't get in, it would not be a waste of time.

Ouyang Houtian quickly understood after seeing it. There were magic weapons here. He widened his eyes in surprise. The magic weapon node appeared. Then opening the gate of Yingzhou Cave Heaven may no longer be an out of reach. (To be continued, please search Piaotianwen, the novel is better and faster!
