Next, Dave and Yang Zhou discussed what life-saving plants there were.

Dave came up with a lot, such as cosmic plants that can break away from the earth and fly long distances, where he can escape, and plants with excellent defense that can go thousands of meters underground, in which he can hide.

There are even plants that have a slower growth cycle, but you can find plants that have kept him asleep for hundreds or thousands of years.

Combined with the Underground Fortress, Dave can sleep in the outside world or in mysterious spaces.

A lot of novel ideas also opened Yang Zhou's eyes, it seems that in order to survive, Dave's imagination has also increased a lot, these are good research and development directions, Yang Zhou feels that there must be these plant types in advanced plants.

Yang Zhou can't help Dave for the time being.

Although Levi is a level 8 host, there are few things he sells that can avoid a crisis of the level of the Great Filter.

It's also a level 3 strengthening tree, and I feel that it will be of some use.

Yang Zhou didn't mention this plant to Dav, since there is a level 3 strengthening tree, there must be a more advanced strengthening plant.

In the future, a more advanced strengthening tree will be considered for purchase.

If it is strengthened to the late stage, and humans can also enter the universe physically, then this plant will be very powerful.

Dave could only wait patiently for Yang Zhou to put new plants on the shelves.

Yang Zhou didn't do nothing, he quickly asked Li Wei if there were any plants among the high-level plants that improved their self-preservation ability and even defended the entire planet.

In the end, the answer was also obtained, this plant naturally exists.

Even if it is the World Tree, it has a very strong defense, a planet has the existence of the World Tree, there is no need to worry about the sun's ultraviolet rays at all, the canopy is equivalent to a magnetic field, which can isolate all kinds of death rays in the universe.

No matter how powerful the plants are, they even have energy covers, but the plants involved in the use of energy are no longer plants of level seven or eight, but plants of at least level 9.

As for Yang Zhou's desire to defend against plants, Levi suggested: "You can build a spaceship, I have already purchased a vine in the sky, and I found that the material of this plant is very special!" It is even more powerful than the materials of some level 8 and 9 plants, and it is completely possible to use this material to improve physical technology. ”

"Also, the big filter doesn't have to be a meteorite, maybe it's a flood crisis? So you can also buy some plants that raise the coastline, or floating plants that float above the sea, which I've seen, are seaweeds that are able to reproduce wildly, and when they die, they form floating islands that almost never sink. ”

"If you want, I can't provide it to you for the time being, but the next time I meet that friend, I will ask him to pay attention to your products and take the initiative to contact you."

Next, Levi also said a lot, all of which were very pertinent suggestions, and even said some of his own speculations.

As Yang Zhou expected, almost all of the people who obtained the system were terminally ill, and their lifespan was only between a few months and half a year.

Of course, Tie Dan is an exception, he is not a normal person.

The system is using the lifespan crisis to make the early host strive to upgrade, and in the later stage, it will also encounter various invisible crises, so that the host will always improve its strength.

Levi even speculated that the system they obtained might be a biological experiment conducted by some high-level being who overrode the multi-universe plane.

Naturally, there is no evidence for these speculations, anyway, what can be determined is that even if Li Wei knows a host of a level 9 Zerg civilization, he also said that the system is not malicious, and everything is the host's own choice.

We must face which path we want to take and how we solve the crisis we are facing.

After communicating with Li Wei, Yang Zhou also determined one thing, that is, the output of space spring water is indeed linked to the grade, at present, Yang Zhou's space spring water only has 128 springs, but at level 7, it is 256 springs, and at level 8, it is 512 springs.

The more springs there are, the more spatial springs will be produced, so that biological civilization can develop faster.

Otherwise, the growth cycle of plants is often decades, hundreds of years, and it is not realistic to rely on natural growth.

After ending the conversation with Levi, Yang Zhou made a decision, which was equivalent to replanning his goals.

Originally, I planned to slowly farm and develop, compete with beautiful countries, and steadily develop biotechnology.

Since we know that there are still aliens in the universe, and the aliens are also likely to kill the earth after discovering the earth because of their soul energy.

Then you can't sit back and wait any longer.

It is necessary to develop into the interstellar age as soon as possible, so that there is more room for maneuver in the universe.

Even if it really comes to the last moment, there is still a way to enter the universe and wander.

Of course, what Yang Zhou wants is to develop all 8 planets in the solar system first, and then see what the big filter crisis is, and be ready to run away at any time.

It's not that Yang Zhou is selfish, but if he really encounters an existence that can destroy mankind, Yang Zhou has almost no other way to go except to escape with his relatives and friends.

After escaping, you can slowly come back to seek revenge from an unknown civilization, and if you sit still, it will be gone.

On the plan, Yang Zhou solemnly wrote a lot of words.

Many of them are planned around spaceships, as Levi reminded that no matter what the crisis encounters, it is absolutely the right choice to get a spaceship first.

At this stage, it is impossible to build a spaceship from plants, so we can only rely on the progress of material science and technology brought by plants, and use physical means to build a spaceship that can escape at any time.

This is followed by the establishment of bases on the Moon, Mars, and so on.

In the middle, the internal circulation system of the spaceship is involved, and if you sail in the universe for decades, what plants can absorb the energy of the universe to produce water, oxygen, and so on.

And Yang Zhou feels that there is no need to be so conservative, for example, the power generation tree should also be taken out as soon as possible.

Plants that can generate electricity, in fact, the earth also has it, there is a kind of tree that generates electricity in the Indu forest, if you accidentally touch its branches, you will immediately feel as uncomfortable as electric shock, so it is called an electric tree, this kind of tree will only produce electricity in the morning and afternoon when there is sunlight, and at night when there is no sunlight, it will not produce electricity.

Scientists have found that the reason why this tree can be charged is because there is an element of "silicon" in the tree, which forms the form of solar silicon cells in its body, so when exposed to sunlight, it will generate electricity like a solar cell.

Yang Zhou could have used the excuse to study the electric tree, and finally changed the gene to study the power tree.

At the same time, it also releases the skyward vines and metal vines.

Scientists have already come up with the answer to the problem of gene locks, because YZ bacteria themselves have gene locks, and there is a high probability that modified plants will also have their own gene locks.

This has been verified in the cancer plants, weight loss plants, fitness plants, AIDS plants, and tranquilizer trees that Yang Zhou took out.

Counting it carefully, there are really a lot of black technology plants flowing out of Yang Zhou's hand.

It's just that many of them have not yet been commercialized, after all, the special effects of plants, large-scale use, must be planted for a long time, and only small-scale verification can use space spring water.

Yang Zhou decided to stare at the various plants that he took out for the next period of time, and then take out some of the profits and invest some of them in aerospace technology, preferably using supermelt materials to build a super shelter, plus a spaceship.

After leaving a way out, you will be able to go all out to develop biotechnology, and no matter what you will face in the future, you will be able to deal with it with a little calm.

And with Dave in front, at least you can know what Dave will face, which has a certain reference significance.

After the rough planning, Yang Zhou casually threw the plan paper into the space, his space is the biggest secret, Yang Zhou still didn't understand that the system host can hide in the mysterious space even if it encounters danger?

It's completely self-sufficient here, and it stands to reason that it won't die.

It seems that if you want to verify this, you will have to wait for Dave to know the situation when there is a crisis in the future.

In the end, whether Dave can be saved depends on whether there are suitable plants, if there is, Yang Zhou will definitely save it, Dave has 30 billion experience points! It's all heartwarming to hear.

If Yang Zhou uses supermelt materials to build a shelter and a spaceship, Yang Zhou will also fool Dave into buying it, if Dave buys Yang Zhou's own plants and does not occupy a stall, then it is really a good person!

Before promoting his Chaotian Grapevine, Yang Zhou was ready to upgrade Chaotian Grapevine again, and it would be worth at least 1 billion or 2 billion experience points to meet Dave's worth.

Besides, with the space elevator plant, it is easier for Dave to go to the sky.

Yang Zhou is all for Dave's sake!

After planning the future, Yang Zhou's mood returned to stability, and when he returned to reality, it was still his own room, Tang Yue naturally couldn't sleep with him, and his father-in-law and mother-in-law were still there.

Now there are temporary hotels in Red Beach, and they all live in hotels.

This time, Yang Zhou was not going to return to the capital so soon, in addition to taking out a few new plants in the Red Beach Laboratory, Yang Zhou was also going to go to the Jiuquan Aerospace Base to have a look.

I don't know if they use supermelt materials in aero engines or rockets.

In recent years, aerospace has developed rapidly, not only taking lunar soil, but also sending probes to Mars, and even the space station has its own.

There are now three astronauts on the space station.

Yang Zhou hopes that his participation will speed up again, at least relying on supermelt materials to build a space shuttle.

In the past, there was this thing in a beautiful country, but later because a space shuttle had 2.5 million parts, it was very difficult to maintain, and once an accident occurred, there was no chance of survival, and it was finally eliminated.

But now Huaguo has supermelt materials, and is not afraid of general high temperatures at all, and the probability of accidents is greatly reduced.

Aviation aircraft can also be developed.

Of course, if the space elevator plant succeeds in the future, it will be easier and more convenient for humans to go to space.

You can even build a space city in space.

Yang Zhou was a little looking forward to it, when Huaguo has a space elevator and is still using rockets to transport abroad, what will be the expressions of those foreigners who feel superior to others at that time.

In many cases, we can completely ignore what others think, just bury our heads in development, and after leading in all aspects, it is others who kneel and lick us.

Of course, the necessary means of defense at the strategic level must also be available, and when the space base is completed, it seems that it is not very difficult to develop a space-based weapon?
