After making an appointment with Optimus Prime for a transaction, Sun Cheng didn't stay long with the forerunner and left quickly.

He didn't know if the predators had been awakened now, so it was dangerous to stay longer.

King Pu, who is extremely hostile to the Decepticons, has the combat power that even Megatron is afraid of.

During the Cybertron Civil War, he had suppressed the Decepticons for a long time by personal force, and was called the strongest existence under the Thirteen Ancestors by the Autobots, which was obviously not something that the current Sun Cheng could deal with.

As for how much Optimus Prime believed, he didn't care.

Sun Cheng didn't expect Optimus Prime to fully believe in himself, on one side he was his former teacher, and on the other side he was a Decepticon traitor.

However, as long as he began to have doubts in his heart, it was enough, so as not to cause trouble in the future, and Optimus Prime did not react at all.

Instead of returning directly to Trindaddy Island, Sun Cheng separated from the Precursors over the South Atlantic.

The Forerunners, who already possess the combat power of elite warriors, will continue to be stationed on Trindaddy Island.

He already had plenty of experience before, so Sun Cheng believed that the pioneers would be able to rebuild Trindaddy Island or manage and protect the black market in the future.

As for himself, he returned directly to Base 2.

Before the black market was invaded, Sun Cheng had already realized that the earth was no longer safe, and Base 2 might have been exposed.

After the invasion of Trindaddy Island by the Red Spider's legion of replica warriors, this idea was undoubtedly strengthened.

The sense of crisis that hit the door made Sun Cheng decide to increase the Mars base.

He was going to Mars again, this time not only to transport a large number of supplies, but also to use the spherical space to transport a group of Decepticon engineers, technicians, and sappers after they were all dormant.

After this idea came up, Sun Cheng had already informed the second base in advance and asked them to start screening people who volunteered to go to Mars.

The environment and conditions over there are undoubtedly much worse than the No. 2 base that has now taken shape.

The status of the sappers and technical officers is relatively low, and Sun Cheng will not care too much about their attitude, basically the list is arranged by the base, and this batch he is ready to send two hundred sappers, technical officers, and fifty Decepticon warriors to Mars at once.

However, on the side of the Decepticon engineer and senior engineer, he still has to give a little face to these subordinates who have followed him for several years.

At first, Sun Cheng would let them recommend themselves or each other to the list of people who went to Mars according to their wishes.

He gave a list of ten things, and only when his Decepticon engineers and senior engineers were dissatisfied with their self-recommendation, they would personally select and fill in the list.

I had already informed in advance that when Sun Cheng returned to Base No. 2, everything was ready.

"Master, everything has been selected according to your requirements, from personnel to supplies. The Hope has also completed its testing and its energy has been replenished. ”

Nodding, Sun Cheng ordered directly, "Let them start gathering and start hibernating!" ”

He connected to the central master control brain of Base 2, and instantly found that on the list provided by 'Phantom', there was not a single Decepticon senior engineer who was sent to the Mars base this time, and only two of the ordinary engineers were old people who had followed him for more than a year, and the rest were all newly promoted Decepticon engineers who had just been promoted in batches not long ago.

For this list, Sun Cheng could not say that he was disappointed.

Decepticons, like humans, have all kinds of desires and greed.

At present, the situation on Mars is full of unknowns, because the relationship between the new base has just been established, and all kinds of materials and conditions are worse than those on Earth.

Although the Decepticons can survive in the universe for a long time and stay in various harsh environments, it does not mean that they like to stay on Mars, where the atmosphere is thin and various harsh environments are frequent.

"I hope you don't regret it in the future!"

The knowledge of the new Decepticon engineers is not much worse than that of some of the old Decepticons, mainly in terms of experience and private research skills.

Therefore, Sun Cheng did not show dissatisfaction with the willingness of only two Decepticons with relatively old qualifications to go to Mars.

But in the future, the main person in charge of the Mars base will definitely give priority to selecting from the Decepticons sent to the Mars base in the previous batches.

And once the earth is really in chaos, the safety of the future No. 2 base will not be comparable to that of Mars.

Sun Cheng also knew that in the future he would have self-righteous Decepticon engineers under him, who would be annoyed by today's choice.

The agreed trading time with Optimus Prime is a month later.

It takes time to prepare materials and equipment, and it also takes time for the Autobots to extract energy from the [Leadership Module].

Therefore, Sun Cheng decided to take advantage of this time to go to Mars.

With his order, the second base immediately became busy.

Voluntarily, as well as Decepticon engineers, engineers, and technical officers selected by the base, as well as dozens of Decepticon warriors, all fell into dormancy with the help of the doctors.

Spherical space is Sun Cheng's biggest secret, he has done experiments in private before, and he can fit live animals and living miniature Decepticons into it.

This discovery made him both happy and worried, but since then, Sun Cheng has also been more careful.

Even if he had to put Skyfire and other Decepticons into the ball-shaped space, he would need to make sure that the opponent was dormant before he could temporarily put them in the ball-shaped space.

In the huge warehouse, rows of containers ranging in height from three to five meters and with completely different specifications are neatly stacked in the warehouse.

Sun Cheng quickly loaded these containers into spherical space one by one, and this time he will stay alone in the spacecraft on his trip to Mars.

After returning from the last experimental fire exploration trip, the Decepticon engineers under his command once again underwent a series of maintenance and modifications on the spacecraft based on the various data collected during the trip.

Now the Hope is a little faster than before, and various stability and performance have been improved.

Entering the cockpit and sitting down, Sun Cheng immediately communicated with the pseudo-intellectual brain on the spaceship.

"Hope, activate the optical stealth device...... Target: Mars...... The exact coordinates have been entered, ready to go......"

"The command has been accepted and the power system is turned on...... Optical stealth device opens ......"

After the optical stealth device was activated, the Hope test spacecraft seemed to be shrouded in a cloud of water.

Although the four cooling tails emitted by the engine cannot be completely obscured, the optical stealth device is still able to obscure most of the observation equipment on Earth.

Soon, the spacecraft took off from a launch site in Base 2 along a calculated flight trajectory, escaped the Earth's gravity at a very fast speed, and began to fly in the direction of Mars.

Sun Cheng also began his second trip to Mars.
