Because of Chen Tianhe and Su Yanrong's orders, although Yan Qingyu was slightly dissatisfied with the young Si Chen's command of them, she didn't say much? Instead, let Si Chen say, what kind of sealed place is under this black pool? Is there anything special about it?

Si Chen nodded and said, "According to my understanding, under this black pool, there should be a water system source crystal. According to some historical records, this water system source crystal is a kind of treasure spirit source crystal, which is placed in this black water pool, which is used to provide the source of power of the sealing formation. Therefore, under this black pool, it can only be suitable for some flexible monster planters to enter, and they need to carry the power of heavy water, and at the same time, I don't know if there are other fierce beasts in this black pool? Of course, there are peak spirit-level fierce beasts of this nine-headed giant snake, and it is estimated that there will be no fierce beasts near the Black Water Pool, but it is not excluded that the children and grandchildren of the nine-headed giant snake will be descended. When you enter the Black Water Pool Forest, you will see some black snakes appearing on the dead branches and leaves, so you should not be careless. ”

Seeing that everyone nodded, Si Chen specifically discussed the number of people entering the Black Water Pool, Yan Qingyu was a giant whale beast, and it was the first choice to enter, and Mu Qing's ice and snow giant beast was also selected into it, Yu Ying frowned slightly, I don't know what Si Chen was thinking? Although Mu Qing is an ice and snow beast, he is not as good as the snow butterfly of the sea breeze and snow, but unfortunately, Si Chen, as their commander, seems to have more results in mind.

Therefore, the people who entered the Black Water Pool, in addition to Si Chen, included Yan Qingyu and Mu Qing, as well as Yu Ying. He didn't understand, but Si Chen said that his devouring mystery was of great help at a critical moment, making everyone frown slightly, Yu Ying was uncomfortable, why did Si Chen say it clearly? Isn't this the rhythm that pushes him to the cusp and gives him a ride?

Sure enough, Yu Ying saw Qing Jue's face change slightly, and stared at him directly. Shen Zhou still had a sleek appearance with a smile on his face, and he didn't seem to care about the potential that Yu Ying said. And the leaf wolf and the sea breeze and snow were also slightly dissatisfied, but they were not as obvious as the youth.

As if he didn't see it, Si Chen asked the others to guard on the trees around the water surface of the Black Water Pool, and the four of them had already breathed well because of the time when Yu Ying devoured the essence blood of the nine-headed giant snake, and they were not seriously injured, and although Si Chen had consumed too many demon elements, he had also recovered fifty percent, and he did not delay time at all, and his body was abruptly covered with a layer of white battle armor, but it was more delicate and soft than the Tianyu battle armor of Yu Ying and others, like a higher-level spirit and demon battle armor.

This spirit and demon battle armor is a combat spirit planter that takes into account the sea, land and air, and can cover the whole body, so Si Chen took the lead and plunged into the black water pool with a radius of 100 meters.

And Yu Ying also used the Tianyu battle armor to fully cover his body, only revealing a pair of eyes, looked at Mu Qing next to him, nodded slightly, and plunged into follow, so did Mu Qing. And Yan Qingyu was at the back of the hall.

Entering the pool water, Yu Ying immediately saw a light turned on above Si Chen's head, illuminating the water, and immediately followed behind Si Chen, and found that the water was clear and there were no impurities, probably because of the heavy water, but there were fallen leaves floating on the water surface, which should be the place where the source crystal of the water system would show the characteristics of heavy water.

Yu Ying was worried about Mu Qing, and when he saw her following behind him, he wanted to go over, pull her, and swim down with Si Chen, but when he saw Mu Qing stubbornly shaking his head, he was slightly stunned, and he was not stubborn.

The depth of this black pool seems to be not small, and the four of them are estimated to have swam down for more than ten minutes, but they have not yet reached the end, but they already have some characteristics of heavy water on them, so they are pressed on them, and on the contrary, they swim faster downward.

Yu Ying secretly screamed that it was not good, I don't know the depth of this black pool, if you let the power of heavy water be blessed on your body, if it is too big to compete with at that time, won't you be pressed into the bottom? Although this has been discussed before, everyone doesn't seem to pay much attention to it? Now that I really feel it, my heart trembles, and my scalp is slightly numb.

Yu Ying hurriedly used the communicator to tell Si Chen about the situation.

Si Chen told them that although this water system source crystal is a heavy water source crystal, the characteristics of heavy water are not too strong, and with the spirit and demon battle armor and his own cultivation, he should be able to withstand the power of heavy water, not to mention, with him, a space demon planter, next to him, even if something is wrong, he can use the power of space to escape from this ghost place?

Although Yu Ying still felt uneasy, what Si Chen said was not unreasonable, and this mission, which was recorded at the theater level, was not an ordinary mission, and there was no room for bargaining at all, so he had to continue to follow Si Chen.

As the heavy water intensified, Si Chen suddenly stopped under the water and shouted through the communicator: "Everyone be careful, there seems to be a fierce snake around?" Quickly turn on the realgar odorant. ”

Before the words fell, a black snake appeared on Si Chen's left, with a thigh thick, more than three meters long, the light was on above Si Chen's head, and the three-meter black snake pounced directly, but was pierced by Si Chen's sword and fell to the bottom of the pool.

Yu Ying was frightened, and hurriedly turned on the snake repellent function of the battle armor, and immediately saw that some large and small black snakes appeared in the water, although they did not have multiple heads, but these black snakes seemed to live in the range of heavy water. His gaze was in this black water, even with the help of the soft light emanating from Si Chen's body, he could only see a range of more than ten meters, and he was worried that those black snakes would suddenly attack. His psionic spear had been exchanged for an ice-type psionic spear, and he was busy holding it in his hand, sensing his surroundings. And Mu Qing also held the wind system spiritual energy battle spear, and almost followed Si Chen down with Yu Ying.

Fortunately, although these black snakes swam over, they had a snake repellent smell on their bodies, which had a huge effect, allowing them to pass through this black snake area without danger and continue to go deeper.

In the end, they roughly measured the depth of the depth, and they dived at least more than 200 meters deep into the black water pool before they almost reached the point. When they fell to the bottom of the pool, they saw a large patch of silt, almost submerging the whole person, but Si Chen seemed to know some of the conditions at the bottom of the black water pool, so he wandered forward for dozens of meters, and the silt at the bottom of the pool was much less, but there were many more ruined stones or some stone pillars, which seemed to be the site of a certain building.

The power of heavy water has been blessed to a great extent, everyone feels that they are carrying more than two hundred catties of heavy objects on their bodies, fortunately, they are all powerful demon planters, this gravity does not affect their speed, they are at the bottom of the pool, climbing these ruined stones, looking forward, but unfortunately, the surroundings are pitch black, and there is no trace of the water system source crystal.

Si Chen summoned the three of them over, and told them through the communicator that the power of the heavy water of the ruins in the ruins had reached its strongest, so he asked the four of them to divide into three teams and look for them at the bottom of the pool in the ruins.
