In the next few days, Chen Chen stayed by Rosalind and his son. While taking care of them with peace of mind, he could also accompany his family more because he knew that such a peaceful day would not last too long.

As time goes by, the energy contained in Kadalin's Heart has been further absorbed, and the combat value has exceeded 9 million, which is only one step away from the tens of millions.

But this step is not so easy to achieve.

The battle value is increased, the more difficult it becomes. At the beginning, it is more than tens or hundreds of points, and it feels like it is a lot. After that, every level is increased, the required values ​​are tens of thousands, which are completely inconsistent with the previous one.

Being able to reach this point is to rely on short-term release authority to go to different planes to obtain extremely powerful sources of power. In addition to obtaining the Heart of Kadalin, you can quickly improve to this level. If you have absorbed the Heart of Kadalin, if you cannot obtain more sources of power, then the subsequent improvement will not be so easy.

At present, although Kadalin's heart has not been fully absorbed and the remaining energy is enough to increase his combat value by millions, it will be a long-lasting process that cannot be achieved in ten days and half a month.

Judging from all the signs, the battle value of the Nether King is probably beyond the tens of millions of levels. The strength comparison is the increase and decrease of one another. If he cannot improve quickly, he will be left behind.

Thinking of this, Chen Chen couldn't rest.

It seems that we have to find other ways to improve.

But now I have used all the ways I can use them, and I have visited several powerful planes. After thinking about it carefully, I found that there was nothing that could improve my strength.

In the end, I could only return to the Kadalin Crystal.

This crystal contains powerful quantum power. By absorbing quantum power, one can continuously enhance one's mental power and willpower to increase its combat value. It was previously achieved by relying on this method.

Now, although Kadalin's Heart has been absorbed, Uranus still has rich Kadalin crystals. If absorbed, the combat value can also be increased rapidly. This is the best way to think of at present.

In addition, over the past so long, Renard and Kellygan should have made progress. The Uranus Fortress system should have been almost designed and needs to be improved on the spot.

If the two purposes are combined, you must go to Uranus.

After making up his mind, Chen Chen told Rosalind and his parents about his ideas.

Everyone did not stop this.

They understood the responsibilities that Chen Chen shouldered. Now the rise and fall of human beings on the earth are all about him. After all, he is no longer an ordinary person, not only a father, a husband, and a son, but also the hope of mankind.

Although he was reluctant to leave, he couldn't hold him back.

In such a complicated mood, full of affection and advice, the family waved goodbye and watched Chen Chen board the cockpit of the titanium fighter jet and flew towards the distant starry sky.

With the help of hyperspace jumping sailing, Chen Chen soon arrived at the surface of Uranus.

At this time, Uranus had initially had the prototype of a fortress system. The orbital periphery was surrounded by secret observers to monitor the entire airspace in the dark, and there were spherical intelligent aircraft cruises in stealth.

On the surface of Uranus, a thousand violent and a thousand deep cold are scattered in various bases, and hundreds of automatic mining equipment are working hard to bring together the collected Kadalin crystals.

Under the remote sensing of the witch, a basic system has been formed. Once the patrol observer and the spherical smart phone find an abnormality, they will immediately come forward to detect it. At the same time, all the rage and deep cold will be activated to face all possible invading enemies.

However, this is just to form an outer base, and to truly become a fortress, there is still a lot to prepare.

After landing, Chen Chen immediately entered the plane prison and went to the heavy factory to find Renard and Kellygan.

At this time, the two were assembling a large instrument.

There is a prototype base at the bottom of this instrument, and above it is a cylindrical object like a tower, which is smooth and smooth, looking like a giant cannon, but Chen Chen knew that this was definitely not a giant cannon.

With the cleverness of Renard and Kellygan, he would not make such a live target weapon, which must be another important device.

Chen Chen has noticed that there are more than one such device, and four of them have been prepared on the spot.

"This is a large observation device, installed on Uranus, and the starry sky at the edge of the solar system can be observed." Renard explained in time, dispelling Chen Chen's doubts: "The four units are distributed in four different locations and operate with Uranus, which can ensure no blind spots around the clock, which constitutes the first step in early warning!"

"At the same time, the most important point." After pausing, Renard added: "Humans have not been in the universe for a long time, and even the solar system's star navigation map has not been completely mapped. This device will follow the revolution of Uranus and map the star navigation map on different axes. According to the revolution time of Uranus, it will take 82 years to map the complete solar system's star navigation map!"

"It's been a long time..." Hearing this time, Chen Chen couldn't help but sigh.

"The universe is very vast, and the exploration of the waterway is not something that can happen overnight." Kellygan said with a smile: "You must know that there are so many civilizations in the Milky Way, but it has not been successfully mapped for thousands of years. Otherwise, how could the Earth have the opportunity to develop safely for thousands of years in this unknown corner?"

"Okay, these are the future things." Chen Chen calmed down and then asked his most concerned question: "How is the entire defense system?"

"We need to continue the topic above." Renard reached out and pulled out a floating window to show the general composition of the solar system: "Because the surveying and mapping of the Star Aerial Map cannot be accomplished overnight. In fact, there is only this one known channel at present!"

As he said that, Renard marked a red line on the map: "That is, the route that ancient humans left and then returned, and they took, and that is the route you have been using. This is the only channel that all civilizations in the Milky Way have mastered to enter the solar system!"

"Except for this channel, the rest of the range belongs to unknown areas." Renard spread his hands and smiled: "So, before further exploration, no one dares to go through these areas. In a short period of time, there is only one gateway to the solar system, one road!"

"According to Uranus' revolution time, Uranus will not deviate too far from the axis of this channel within two years." Kellygan took the conversation aside: "Therefore, the Uranus Fortress you proposed was actually established in a short period of time. In the past one or two years, Uranus can serve as a gate to defend this route. As for one or two years, Uranus will deviate from the axis of this channel as it revolves, that's another matter."

"Actually, the most important thing is the past or two years." Chen Chen naturally understood the truth and nodded at the moment: "The main threat at present is the Babylonian Empire and the Star Alliance. Within a year, I should have eliminated this hidden danger."

"Okay, after talking about the above, let's talk about the fortress system." Renard reached out and dragged the display floating window, and replaced it with Uranus' topographic map: "A general fortress is to renovate the entire planet, or even install super weapons, but Uranus keeps moving and will soon leave the channel axis. In addition, it is too large and it consumes too much resources to build the fortress, so we can't afford it, and there is no need."

"To block this channel, a fixed fortress system must be built manually. According to our design, large thrusters are adopted to directly move a giant meteorite or even an asteroid to the channel axis and build it into a base, equipped with various weapons on the outside, and the internal ones are warship ports and command centers to form a defense system."

"The fortress that is still moving is indeed the only passage that the permanent surname blocks." Chen Chen pondered for a moment and asked again: "But what if another channel is discovered in the future?"

"Within eighty-two years, humans on Earth can obtain a complete solar system star navigation map, and then all the existing waterways will be discovered." Renard replied without hesitation: "After that, on all the waterways, such fortresses will be built, with several waterways, and all of them will be blocked!"

"Eighty-two years are already very short!" Renard sneered, and his eyes flashed: "I don't believe that any civilization can discover other channels in such a short time."

"Okay, that's a long-term thing." After thinking about this, Chen Chen immediately calmed down: "Let go of the future first, I'll leave the fortress plan to humans. Let's talk about it in front of me, where is Uranus Fortress?"

"Then let's talk about Uranus!" Renard dragged the floating window again to enlarge the Uranus topographic map: "Twenty-seven satellites form the first defense, and build an observer and smart phone launch base on it. The vast star field around Uranus is patrolled by observers and smart phones, forming the outermost cordon."

"Then, there are a large number of ice cracks on the surface of Uranus, which directly lead to the internal rock formation!" Renard enlarged one of the ice cracks and showed the internal situation: "The Atlantis have built many facilities in these ice cracks, and they have been transformed into deep cold bases. Countless deep cold will rely on these bases to eliminate all invading enemies."

"If the enemy was really powerful and withstood the cold attack, they could not bypass Uranus, because this thorn was firmly nailed to their throats. They had to capture Uranus. At this time, they could only choose to land." A sneer appeared on the corner of Renard's mouth: "And once landed, the violent will be waiting for them on the ground."
