In the center of a gorge with beautiful mountains and rivers, there is a large gray-white rocky ground. Circle after lap of stone walls that are less than ankle high, enclosing large and small pools of water. The water is crystal clear, greenish in color, and sometimes rippling in the microwave.

There are about 300 pools. Some pools are topped by huge balls suspended from the sky. The balls rotate slowly, and the colors are single and varied.

Du Shen led Bai Su'er and the four of them to walk in the middle of the pool.

This is the center of control for the Orb of the Force and the Sea of the Force. Du Shen is teaching the four of them how to control and what to pay attention to.

Du Shen pointed to the huge ball of light above a certain pool and said, "The Force is actually the origin of the world. If you extract too much, you will definitely cause damage to the world and make it die out early. Therefore, you need to collect the Force Orbs regularly and re-send them to the new world. ”

Du Shen went on to explain the principle and function of the photosphere.

Du Shen's lectures were intermittent and lasted for more than ten days. He often set aside time for Bai Su'er and the four of them to think about and digest.

After all, the Sea of the Force is inherently a very complex system. Not to mention that the total number of Force Orbs is close to three hundred, and the fragments are scattered in tens of thousands of small worlds. The affairs that Bai Su'er and the four of them need to undertake are myriad.

The canyon here is a small world of its own. Du Shen simulates the changes of the celestial phenomena of the rising sun and the setting of the moon.

In the evening, the sun set, and the sea of stars in the dome shone early. Du Shen summoned Bai Su'er and the four of them at the side of the house in front of the waterfall.

Du Shen sat cross-legged with his back to the silver-white waterfall. The waterfall roared, and Du Shen used a spell to hide the sound, so as not to affect ordinary conversation.

Du Shen glanced at the four people: "What should be explained, I have already explained it clearly." Do you have any doubts?"

Bai Su'er and the four of them looked at each other, but they didn't speak for a long time.

Du Shen stood up: "Since you have no doubts, then I will go back to the past." ”

"Wait a minute," Bai Su'er raised her hand to stay, "You don't have to be in such a hurry, right?

"I'm well prepared," Du Shen slowly walked towards the three hundred pools down the hillside, "Actually, not long after the rebirth of the avatar you are familiar with, I started to prepare. More than 100 years of preparation should not be further delayed. After I'm gone, you do what you can. ”

"Wait a minute," Bai Su'er stepped across, blocking Du Shen, "I don't think you can leave yet." ”

"I think so," Lin Caiying also stepped over and made a gesture to stop Du Shen, "You travel through time and space, and you actually want to take most of the Sea of Force with you." The remaining Sea of Force simply can't stop the spread of the Mixed Hole. In case your operation fails. What do you call us and thousands of worlds to do?"

"I didn't explain it very clearly," Du Shen said calmly, "I need the Sea of Force to block the erosion caused by time rewinding. In order to preserve the sanity, in order to have the most basic power to change history. I must take the Sea of the Force with me. ”

"You can't wait any longer?" Lin Caiying frowned, "Accumulate some more Force power." Until you have enough Force to suppress the spread of the hole!"

Du Shen shook his head: "I hope you can understand." My action this time is the hope of completely eliminating the confusion. You and the remaining Sea of the Force will only delay the destruction of the Cavity. so that you may find new opportunities for redress in the future. If I fail. ”

Du Shen lightly drilled and rushed between Bai Su'er and Lin Caiying. As he walked down the mountain, he continued, "Time flows at different speeds in different worlds. If you want to return to the source of time, you must use the power of the Force Sea. However, because I took with me most of the Sea of the Force that had accumulated over tens of thousands of years. The remaining Sea of Force must be used to ward off the erosion of the Cavern. You don't have the conditions to travel through time and space, so you have to find another way to eliminate the chaos!"

Du Shen's reminder made Bai Su'er and the four of them worried. They turned around and strode and chased Du Shen's figure one after another.

Du Shen walked to a smaller pool. This pool is located in the corner, and the water in the pool is the shallowest and does not look as green as the other pools.

This pool, which corresponds to the universe to which the earth belongs, is also the starting point of Du Shen's shuttle through time and space.

On Du Shen's shoulder, a transparent orb floated. In the beads, there are colorful streamers. The beads are Du Shen's special Nai He beads, and the streamer inside is most of the Force Sea that Du Shen has divided.

However, the colored light in the pearl was active and spread out, making Du Shen's body surface seem to be surrounded by a layer of colorful clouds.

Du Shen turned his head and smiled: "Next, don't come near me." The survival of countless worlds may depend on you!"

After saying that, Du Shen looked at the pool in front of him. He jumped lightly and slowly landed towards the center of the pool. The clear water in the pool suddenly swirled, faster and more intense, so that a small splash splashed out of the pool.

Du Shen's feet had not yet touched the pool water. Bai Su'er suddenly soared. She wanted to teleport and arrive at Du Shen's side immediately. But she found that the space around her was temporarily confined. Bai Su'er struggled to lean and hurriedly reached out to grab Du Shen.

Du Shen was engrossed in controlling the opening of the space-time channel. He couldn't detect the movement behind him. When his feet were all submerged in the water, Bai Su'er's right hand just touched Du Shen's back.

Du Shen was startled and did not react. The passage had been opened, and he didn't have the strength to send Bai Su'er back. He must take full control of the Space-Time Passage and the Force Orb. Otherwise, the shuttle will fail as soon as it begins. Du Shen couldn't even predict the terrible consequences that would follow.

Bai Su'er lightly bumped into Du Shen's back. She half-hugged Du Shen from behind. She didn't dare to move, for fear of disturbing Du Shen.

After a few moments, the condition of the channel stabilized. Du Shen used the colorful force to isolate the long river of time and swim upstream. He sighed softly, "Let go." ”

Du Shen turned around and looked, stunned for a moment: "Why are you all here?"

In the narrow space, Du Shen saw Lin Caiying squeezed behind Bai Su'er. Lim Chae-young's shoulders were on Teresa. Next to Teresa stood Martina.

The four women were all trapped in the time and space tunnel.

"I want to change the past with you. Bai Su'er's explanation was weak-hearted.

Lin Caiying was a little angry: "I want to save Bai Su'er!"

Teresa said seriously: "I'm going to do Lin Caiying a favor." ”

"Me too. Martina echoed, her gaze a little evasive.

"Why are you so reckless? Wasn't I working in vain before?Who will run the rest of the Force Sea?" Du Shen complained, but looked very calm.

Lin Caiying lowered her head in shame for a moment, and then raised her head in an instant: "Didn't you say that going back to the past is the only chance to eliminate the confusion? As long as we can change history, even if the remaining Sea of Force is not running, we will not be afraid!"

"However," Du Shen calmly stated, "in order to maintain the integrity of the individual and consciousness, it is necessary to use the Force to isolate the erosion of time. Originally, I thought I was the only one. So, the Force I carry is only one person's amount. Now, there are five of us!"

Bai Su'er's face turned pale, and she secretly blamed herself.

Lin Caiying wanted to complain: "Why didn't you explain it earlier?" but she couldn't. Because Du Shen didn't need to explain them in detail.

"What if the Force isn't enough," Teressa asked, still calmly, "what if?"

Du Shen always looked calm: "We will turn into basic energy particles and return to heaven and earth." ”

Although Bai Su'er was sad, she approached Du Shen very resolutely: "Then you can kill me! ”

"You can also kill me," Lin Caiying followed up, "In order to eliminate the chaos, you must successfully go back to the past, and you must succeed in changing history." ”

"And me," Teresa squeezed forward earnestly, "but I did it myself. ”

"I'm not afraid of death," Martina said softly, "Actually, I just jumped with everyone when I saw everyone jumping in." ”
